                                  STOCK FUNDS

 ING LARGE CAP GROWTH FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and will invest at least 65% of its total
assets in a portfolio of equity securities of large companies (that is,
companies with market capitalizations of more than $1 billion at the time of
acquisition), which in the Sub-Adviser's opinion possess growth potential. As a
general matter, the Fund expects these investments to be in common stocks.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, four-step investment process that seeks to identify unrecognized
growth and value in large capitalization stocks. The four steps are:

     - First, the universe of companies is screened using models developed by
       the Sub-Adviser to create a list of possible investments;

     - Second, the Sub-Adviser researches the companies identified by the
       screening models. This research includes a review of company management
       and other factors that are more subjective and require the extensive
       practical experience of the portfolio managers;

     - Third, the Sub-Adviser evaluates the return, valuation and risk of the
       remaining potential investments against a defined peer group; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities. The Fund invests primarily in equity
       securities of larger companies, which generally have more stable prices
       than smaller companies.

     - Market Trends.  From time to time, the stock market may not favor the
       large company, growth-oriented securities in which the Fund invests.
       Rather, the market could favor value stocks or small company stocks, or
       may not favor equities at all.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an

 ING GROWTH & INCOME FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities. As a general matter, the Fund expects these
investments to earn income and to be in common stocks of large companies whose
market capitalizations are generally in excess of $10 billion.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, three-step investment process that seeks to identify growth at a
reasonable price. The three steps are:

     - First, the universe of companies is screened using models developed by
       the Sub-Adviser to rank possible investments;

     - Second, the Sub-Adviser researches the companies identified by the
       screening models. This research includes a review of earnings, sales and
       growth, as well as the impact of broad economic trends found within the
       economy upon possible investments;

     - Third, in order to help manage the risk of the portfolio, the
       characteristics of the portfolio are evaluated against certain market
       benchmarks.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Changes in Interest Rates.  The Fund invests in securities that produce
       income and therefore the value of its investments may rise or fall in
       response to fluctuations in interest rates. Generally, when interest
       rates increase, the value of income producing securities may decrease,
       and when interest rates decrease, the value of income producing
       securities may increase.

     - Market Trends.  From time to time, the stock market may not favor the
       income producing securities in which the Fund invests. Rather, the market
       could favor non-income producing large capitalization growth stocks,
       value stocks or small company stocks, or may not favor equities at all.

 ING MID CAP GROWTH FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of companies with market capitalizations
falling within the Russell Mid Cap Growth Index at the time of acquisition
which, in the Sub-Adviser's opinion, possess growth potential. The average
market capitalization and median market capitalization of this index as of its
latest reconstitution was $4.13 billion and $3.15 billion, respectively. As a
general matter, the Fund expects these investments to be in common stocks.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined investment process combining technical analysis and fundamental
research that seeks to identify companies with superior growth characteristics.
The Sub-Adviser also follows certain self-imposed criteria in an attempt to
manage risk.

     QUANTITATIVE ANALYSIS evaluates stocks based on:

     - Market capitalizations (their size based on price and shares outstanding)

     - Minimum stock price

     - Trading history

     - Trading volume

     - Earnings growth

     - Relative financial strength

     FUNDAMENTAL RESEARCH of individual companies emphasizes:

     - Sustainable earnings growth potential

     - Strong balance sheets

     - Cash flow characteristics

     - Reasonable valuations

     - Quality management

     RISK MANAGEMENT discipline stresses:

     - Remaining fully invested at all times

     - Broad diversification among securities and industries

     - Strict adherence to established buy and sell criteria

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       mid-capitalization company, growth-oriented securities in which the Fund
       invests. Rather, the market could favor value stocks or stocks

       of larger or smaller companies, or may not favor equities at all.

 ING SMALL CAP GROWTH FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of smaller companies (that is, companies
with market capitalizations falling within the Russell 2500 Growth Index at the
time of acquisition), which in the Sub-Adviser's opinion possess growth
potential. The average market capitalization and median market capitalization of
this index as of its latest reconstitution was $870 million and $580 million,
respectively. As a general matter, the Fund expects these investments to be in
common stocks.

     In choosing investments for the Fund, the Sub-Adviser employs a disciplined
investment process that combines economic analysis and extensive company
research to identify companies with superior long-term growth potential. The
investment strategy of the Sub-Adviser is as follows:

     - The Sub-Adviser reviews economic and industry trends to develop themes to
       use in the development of the overall portfolio, which in turn helps
       identify specific companies to consider.

     - With regard to companies under consideration, the Sub-Adviser next
       reviews their respective business models and management, and meets with
       senior executives. The Sub-Adviser also analyzes the company's
       price-to-earnings ratios, earnings forecasts and cash flow.

     - Companies that do not meet the expectations of the Sub-Adviser, either
       due to earnings disappointments or other fundamental criteria may be
       sold.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

       condition of the issuer. Equities generally have higher volatility than
       debt securities.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       small company, growth-oriented securities in which the Fund invests.
       Rather, the market could favor value stocks or large company stocks, or
       may not favor equities at all.

 ING GLOBAL BRAND NAMES FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of companies which in the
Sub-Adviser's opinion, have a well recognized franchise, a global presence and
derive most of their revenues from sales of consumer goods. The companies in
which the Fund invests either have leading market positions, or in the
Sub-Adviser's opinion, have the potential to achieve leading market positions in
the foreseeable future. This portion of the portfolio will have investments
located in at least three different countries including the United States. As a
general matter, the Fund expects these investments to be in common stocks of
large companies whose market capitalizations are generally in excess of $10
billion.

     In choosing investments for the Fund, the Sub-Adviser believes that
well-established companies with strong brand names offer the following
investment advantages:

     - First, demand for brand name products should rise as global consumer
       tastes become more uniform;

     - Second, large companies that can leverage doing business on a larger
       scale have enhanced profit potential;

     - Third, perceived product quality and reliability facilitates sales;

     - Fourth, greater recognition leads to brand loyalty; and

     - Finally, brand extensions, or the ability to leverage a company's
       established brand, provide opportunities for growth.

- --------------------------------------------------------------------------------

     The Sub-Adviser employs a two-tiered approach to structuring the Fund's
portfolio with securities that offer growth at a reasonable price. The first
tier, which will comprise about 75% of the portfolio, is composed of core stocks
with stable earnings development, low cyclicality, large market capitalizations
and longer-term investment horizons. The second tier, which will comprise about
25% of the portfolio, is composed of companies possessing higher cyclicality,
smaller market capitalizations and shorter-term investment horizons. This second
tier is expected to provide the Fund with shorter-term performance benefits.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. Rather, the market could favor
       value stocks or small company stocks, or may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

 ING INTERNATIONAL EQUITY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of issuers organized or having a majority of
their assets in or deriving a majority of their operating income in any country
throughout the world, not including the United States. This portion of the
portfolio will have investments in at least seven different countries. The Fund
may purchase securities in any foreign country, developed or underdeveloped, or
emerging market countries. The Fund will not invest more than 15% of its total
assets in emerging market countries.

     As a general matter, the Fund expects these investments to be in common
stocks of large companies whose market capitalizations are generally in excess
of $10 billion. The Fund may also use options and futures contracts involving
foreign currencies.

     In choosing investments for the Fund, the Sub-Advisers employ a highly
disciplined, four-step investment process combining top-down country allocations
with bottom-up fundamental research that seeks to identify companies which will
provide superior relative returns. The four steps are:

     - First, the Sub-Advisers perform a comprehensive analysis of the relative
       value of geographic regions to determine the degree of representation of
       such geographic regions in the Fund's portfolio;

     - Second, such determinations are reviewed by an independent committee
       within the Sub-Advisers;

     - Third, the Sub-Advisers select investments within the selected
       geographical regions based on comprehensive fundamental analysis; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       stocks in markets to which the Fund is not exposed, or may not favor
       equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Emerging Market Risk.  To the extent the Fund invests in emerging markets
       countries, the risks may be greater, partly because emerging market
       countries may be less politically and economically stable than other
       countries. It may also be more difficult to buy and sell securities in
       emerging market countries.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

 ING EUROPEAN EQUITY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of European issuers. The Sub-Adviser
considers European issuers to be companies whose securities are principally
traded in the European capital markets, that derive at least 50% of their total
revenues or earnings from either goods produced or services rendered in
countries located in Europe, regardless of where the securities of such
companies are principally traded, or that are organized under the laws of and
have a principal office in a European country. As a general matter, the Fund
expects these investments to be in common stocks of large companies whose market
capitalizations are generally in excess of $10 billion.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, five-step investment process that seeks to identify underpriced
earnings growth in European companies. The five steps are:

     - First, the Sub-Adviser ranks possible investments according to trading
       volume and liquidity relative to their peers.

     - Second, the Sub-Adviser performs additional screens to determine which
       companies should be further researched;

     - Third, the Sub-Adviser performs fundamental analysis of cyclical and
       non-cyclical market sectors and companies to identify underpriced
       earnings or cash flow growth.

     - Fourth, the Sub-Adviser determines portfolio weightings within each
       sector.

     - Finally, the Sub-Adviser continuously monitors the portfolio to maintain
       favorable risk-reward relationships.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

- --------------------------------------------------------------------------------

       investments decrease. Equity securities face market, issuer and other
       risks, and their values may go down, sometimes rapidly and unpredictably.
       Market risk is the risk that securities may decline in value due to
       factors affecting securities markets generally or particular industries.
       Issuer risk is the risk that the value of a security may decline for
       reasons relating to the issuer, such as changes in the financial
       condition of the issuer. Equities generally have higher volatility than
       debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in markets to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

 ING TAX EFFICIENT EQUITY FUND

     Investment Objective.  The Fund seeks to provide taxable investors with a
high total return on an after-tax basis.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 80% of its total assets
in a portfolio of equity securities whose returns depend upon stock market
prices. The Sub-Adviser will manage the Fund's portfolio in a manner that will
attempt to reduce net realized capital gains each year. An emphasis will be
placed on common stocks of companies which the Sub-Adviser believes to have
superior appreciation potential. As a general matter, the Fund expects these
investments to be in common stocks of large, mid-sized, and small companies.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined investment process, combining macroeconomic analysis and fundamental
company research that seeks to identify growth at a reasonable price:

     - The Sub-Adviser first determines the outlook for market sectors and
       industries based on business cycle characteristics.

     - The Sub-Adviser next searches for companies with improving fundamentals
       and accelerating growth.

     - Finally, the Sub-Adviser assesses company stock prices relative to their
       expected earnings growth rates and to the overall equity markets.

     The Sub-Adviser attempts to minimize tax consequences to investors by
focusing on non-dividend paying or low-dividend paying stocks and by reducing
annual portfolio turnover.

       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or may not favor equities at all.

     - Tax Efficient Management.  The Fund is managed to provide high after-tax
       returns. Therefore, it may not provide as high a return before tax as
       other funds, and as a result may not be suitable for investors who are
       not subject to current income tax (for example, those investing through a
       tax-deferred retirement account, such as an IRA or a 401(k) Plan).

in the marketplace and whose returns depend upon stock market prices. Such
companies generally will have one or more of the following attributes: (i)
valuable fixed assets; (ii) valuable consumer or commercial franchises; (iii)
selling at low market valuations of assets relative to the securities market in
general, or companies that may currently be earning a very low return on assets
but which have the potential to earn higher returns if conditions in the
industry improve; (iv) are undervalued in relation to their potential for growth
in earnings, dividends, and book value; or (v) have recently changed management
or control and have the potential for a "turnaround" in earnings. The Sub-
Advisers will manage the Fund's portfolio in a manner that will attempt to
reduce net realized capital gains each year. As a general matter, the Fund
expects these investments to be in common stocks of large, mid-sized, and small
companies.

     A more detailed discussion of the Principal Investment Strategies is

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of

     - Tax Efficient Management.  The Fund is managed to provide high after-tax
       returns. Therefore, it may not provide as high a return before tax as
       other funds, and as a result may not be suitable for investors who are
       not subject to current income tax (for example, those investing through a
       tax-deferred retirement account, such as an IRA or a 401(k) Plan).

which have had a full calendar year of operations. Since the ING Tax Efficient
Equity Value Fund has not yet commenced operations, there is no performance

 ING FOCUS FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest in a portfolio of 20 to 40
equity securities. As a general matter, the Fund expects these investments to be
in common stocks of large, mid-sized, and small companies.

     The Sub-Adviser seeks to invest the Fund in growth companies that are
positioned to benefit from capitalizing on significant industry, regulatory,
technological, and ownership changes. To find such companies, the Sub-Adviser
looks for management teams with entrepreneurial spirit and a proven talent for
creating value, with a focus on industries expected to drive change in other
industries (for example, technology

and financial services). The Sub-Adviser's investment strategy incorporates the
following elements to identify companies that offer growth at a reasonable
price:

     - The Sub-Adviser performs fundamental economic and business research to
       identify investment themes expected to improve returns on capital and
       drive earnings growth within industries.

     - The Sub-Adviser next analyzes individual companies to identify favorable:

     A more detailed discussion of the Principal Investment Strategies is

and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       growth-oriented securities in which the Fund invests. Rather, the market
       could favor value stocks or may not favor equities at all.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

annual returns and long-term performance. The Fund's past performance is not an

 ING GLOBAL INFORMATION TECHNOLOGY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of information technology companies. The
Fund defines information technology companies as those companies that derive at
least 50% of their total revenues or earnings from information technology,
hardware or software, or related consulting and services industries. This
portion of the portfolio will have investments located in at least three
different countries, including the United States. As a general matter, the Fund
expects these investments to be in common stocks of large, mid-sized, and small
companies.

     The Sub-Adviser believes that because of rapid advances in information
technology, investment in companies within this sector should offer substantial
opportunities for long-term capital appreciation. The information technology
area has exhibited and continues to demonstrate rapid growth, both through
increasing demand for existing products and services and the broadening of the
technology market. Generally, the Sub-Adviser's overall stock selection for the
Fund will be based on an assessment of the company's fundamental prospects. The
Sub-Adviser anticipates, however, that a portion of the Fund's holdings will be
invested in newly issued securities being sold in the primary or secondary
market.

     The Sub-Adviser combines broad industry analysis and bottom-up company
analysis to identify the stocks of companies it believes will become tomorrow's
information technology leaders. In choosing investments for the Fund, the
Sub-Adviser first identifies themes that address industry and technological
changes. Using intensive fundamental research, the Sub-Adviser then analyzes
individual companies worldwide to find those firms most likely to benefit from
the selected investment themes.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in industries to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets
<PAGE>   20

- --------------------------------------------------------------------------------

       operate, less secure foreign banks or securities depositories than those
       in the U.S., and foreign controls on investment.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to a particular industry, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives.

     - Information Technology Risk.  Information technology companies are
       generally subject to the rate of change in technology, which is higher
       than other industries. In addition, products and services of companies
       engaged in the information technology industry are subject to relatively
       high risks of rapid obsolescence caused by scientific and technological
       advances. Swings in investor psychology or significant trading by large
       institutional investors can result in significant price fluctuations and
       stock price declines.

annual returns and long-term performance. The Fund's past performance is not an

 ING GLOBAL COMMUNICATIONS FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of communications companies. This portion of
the portfolio will have investments located in at least three different
countries, including the United States. As a general matter, the Fund expects
these investments to be in common stocks of large, mid-sized, and small
companies.

     The Fund considers communications companies to be those that derive at
least 50% of their total revenues or earnings from designing, developing,
operating, financing, manufacturing or providing the following activities,
products and services: communications equipment and service (including equipment
and services for both data and voice transmission); electronic components and
equipment; broadcast (including television and radio, satellite, microwave and
cable television); computer equipment, mobile telecommunications and cellular
radio and paging; electronic mail; local and wide area networking and linkage of
work and data processing systems (collectively, "communications activities").

     The Sub-Adviser believes that because of rapid advances in communications,
investment in companies within this sector should offer substantial
opportunities for long-term capital appreciation. The communications area has
exhibited and continues to demonstrate rapid growth, both through increasing
demand for existing products and services and the broadening of the technology
market. Generally, the Sub-Adviser's overall stock selection for the Fund will
be based on an assessment of the company's fundamental prospects. The

       industries. In addition, products and services of companies engaged in
       the communications industry are subject to relatively high risks of rapid
       obsolescence caused by scientific and technological advances. Swings in
       investor psychology or significant trading by large institutional
       investors can result in significant price fluctuations and stock price
       declines.

     - Governmental Regulation.  Certain communications industries, such as the
       telecommunications industry, may be subject to greater governmental
       regulation than many other industries. Accordingly, such industries may
       be subject to changes in governmental policies and the need for
       regulatory approvals may have a material effect on the products and
       services offered. Telephone operating companies in the United States, for
       example, are subject to both federal and state regulation affecting
       permitted rates of return and the kinds of services that may be offered.

which have had a full calendar year of operations. Since the ING Global
Communications Fund has not yet commenced operations, there is no performance

companies. The Fund defines internet technology companies as those companies
with internet businesses or internet related consulting or services businesses,
or that derive at least 50% of their total revenues or earnings from business
operations in internet related hardware, software or infrastructure industries.
As a general matter, the Fund expects these investments to be in common stocks
of large, mid-sized, and small companies.

     The Sub-Adviser believes that the internet is in the early stages of a
period of promising growth. The internet has enabled companies to tap into new
markets, use new distribution channels and do business with end users of their
products all over the world without having to go through wholesalers and
distributors. The Sub-Adviser believes that investment in companies related to
the internet should offer substantial opportunities for long-term capital
appreciation. Generally, the Sub-Adviser's overall stock selection for the Fund
will be based on an assessment of a company's fundamental prospects. The
Sub-Adviser anticipates, however, that a portion of the Fund's holdings will be
invested in newly issued securities being sold in the primary or secondary
market.

     In choosing investments for the Fund, the Sub-Adviser first identifies
themes which it believes will drive the internet in the future. Then, by
conducting extensive fundamental research, the Sub-Adviser analyzes individual
companies worldwide to identify those firms that are most likely to benefit from
the selected investment themes.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in industries to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to a particular industry, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives.

     - Internet Technology Risk.  Internet and internet-related companies are
       generally subject to the rate of change in technology, which is higher
       than other industries. In addition, products and services of companies
       engaged in internet and internet-related activities are subject to
       relatively high risks of rapid obsolescence caused by scientific and
       technological advances. Swings in investor psychology or significant
       trading by large institutional investors can

 ING INTERNET FUND II

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of U.S. and non-U.S. internet
technology companies. The Fund defines internet technology companies as those
companies with internet businesses or internet related consulting or services
businesses, or that derive at least 50% of their total revenues or earnings from
business operations in internet related hardware, software or infrastructure
industries. As a general matter, the Fund expects these investments to be in
common stocks of large, mid-sized, and small companies.

     The Sub-Adviser believes that the internet is in the early stages of a
period of promising growth. The internet has enabled companies to tap into new
markets, use new distribution channels and do business with end users of their
products all over the world without having to go through wholesalers and
distributors. The Sub-Adviser believes that investment in companies related to
the internet should offer substantial opportunities for long-term capital
appreciation. Generally, the Sub-Adviser's overall stock selection for the Fund
will be based on an assessment of a company's fundamental prospects. The
Sub-Adviser anticipates, however, that a portion of the Fund's holdings will be
invested in newly issued securities being sold in the primary or secondary
market.

     In choosing investments for the Fund, the Sub-Adviser first identifies
themes which it believes will drive the internet in the future. Then, by
conducting extensive fundamental research, the Sub-Adviser analyzes individual
companies worldwide to identify those firms that are most likely to benefit from
the selected investment themes.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in industries to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of
<PAGE>   24
ING FUNDS TRUST                                                               21
- --------------------------------------------------------------------------------

       issuers may cause the Fund's share price to fluctuate more than that of a
       diversified investment company.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to a particular industry, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives.

     - Internet Technology Risk.  Internet and internet-related companies are
       generally subject to the rate of change in technology, which is higher
       than other industries. In addition, products and services of companies
       engaged in internet and internet-related activities are subject to
       relatively high risks of rapid obsolescence caused by scientific and
       technological advances. Swings in investor psychology or significant
       trading by large institutional investors can result in significant price
       fluctuations and stock price declines.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Internet Fund
II has not yet commenced operations, there is no performance information
included in this Prospectus.

 ING BALANCED FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  The Fund primarily invests in a
combination of mid- and large-capitalization equity securities, intermediate
maturity fixed income securities and money market instruments. Equity
securities, which include common and preferred stocks, warrants and convertible
securities, are acquired for capital appreciation or a combination of capital
appreciation and income. Fixed income securities, which include investment grade
corporate debt obligations (for example, rated at least BBB by Standard & Poor's
Rating Group or Baa by Moody's Investor Services) and U.S. Government
securities, are acquired for income and secondarily for capital appreciation.
Money market instruments mature in 13 months or less from the date of purchase
which include U.S. Government securities and corporate debt securities
(including those subject to repurchase agreements), certificates of deposit,
bankers acceptances and commercial paper. The Fund may also invest in
mortgage-backed securities and asset-backed debt securities and use options and
futures contracts involving securities, securities indices and interest rates.
The Fund will operate as a diversified fund.

     The percentage of assets invested in equities, fixed income securities and
money market instruments will vary from time to time depending upon the
Sub-Adviser's judgment of general market and economic conditions, trends in
yields and interest rates and changes in fiscal or monetary policies. Depending
upon the Sub-Adviser's determination of market and economic conditions,
investment emphasis may be placed on equities or fixed income securities. The
allocation between equities and fixed income securities creates an opportunity
for investors to receive competitive returns of capital growth and income while
maintaining diversification. Under normal market conditions, the Fund will
invest at least 25% of its total assets in fixed income securities. The average
maturity of the fixed income securities held by the Fund will normally
approximate five years, although this will vary with changing market conditions
and opportunities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Equity Investments.  Equity securities face market, issuer and
       other risks, and their values may go down, sometimes rapidly and
       unpredictably. Market risk is the risk that securities may decline in
       value due to factors affecting securities markets generally or particular
       industries. Issuer risk is the risk that the value of a security may
       decline for reasons relating to the issuer, such as changes in the
       financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

       Interest Rate Risk -- In general, when interest rates go up, prices of
       fixed income securities go down.

       Default Risk -- An issuer of a security may default on its obligation to
       pay principal and/or interest.
<PAGE>   25
 22                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk -- An issuer of a security may prepay principal
       earlier than scheduled, which could force the Fund to reinvest in lower
       yielding securities.

       Extension Risk -- Slower than expected principal payments on a
       mortgage-backed or asset-backed security may extend such security's life,
       thereby locking in a below-market interest rate, increasing the
       security's duration and reducing the value of the security.

     - Allocation Risk.  The Sub-Adviser's judgment about the attractiveness and
       risk adjusted return potential of particular asset classes may prove to
       be wrong. By utilizing the balanced approach described herein, the Fund's
       net asset value may not rise as rapidly or as much as the stock market
       during cycles of rising stock prices.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Balanced Fund
has not yet commenced operations, there is no performance information included
in this Prospectus.

 ING EMERGING MARKETS EQUITY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of emerging market issuers. The Fund will
typically maintain investments in at least seven emerging market countries and
will not invest more than 25% of its total assets in any one emerging market
country. The Fund defines an emerging market country as any country the economy
and market of which the World Bank or the United Nations considers to be
emerging or developing or any country determined by the Sub-Advisers to have
emerging economies or developing markets. The Fund considers emerging market
issuers to be companies the securities of which are principally traded in the
capital markets of emerging market countries; that derive at least 50% of their
total revenue or earnings from either goods produced or services rendered in
emerging market countries, regardless of where the securities of such companies
are principally traded; or that are organized under the laws of and have a
principal office in an emerging market country.

     As a general matter, the Fund expects these investments to be in common
stocks of large, mid-sized, and small companies. The Fund may also use options
and futures contracts involving foreign currencies.

     In choosing investments for the Fund, the Sub-Advisers employ a highly
disciplined, four-step investment process that seeks to identify unrecognized
growth potential in stocks of emerging market issuers. The four steps are:

     - First, the Sub-Advisers perform a comprehensive analysis of the relative
       value of geographic regions to determine the degree of representation of
       such geographic regions in the Fund's portfolio;

     - Second, such determinations are reviewed by an independent committee
       within the Sub-Advisers;

     - Third, the Sub-Advisers select investments within the selected
       geographical regions based on comprehensive fundamental analysis; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources,
<PAGE>   26
ING FUNDS TRUST                                                               23
- --------------------------------------------------------------------------------

       narrower product lines and less depth of management. The securities of
       mid-sized companies may be subject to more volatile market movements than
       securities of larger, more established growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks of companies located in more developed countries,
       or may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Emerging Market Risk.  Because the Fund invests primarily in emerging
       market countries, the risks may be greater, partly because emerging
       market countries may be less politically and economically stable than
       other countries. It may also be more difficult to buy and sell securities
       in emerging market countries.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Emerging
Markets Equity Fund has not yet commenced operations, there is no performance
information included in this Prospectus.

 ING GLOBAL REAL ESTATE FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of companies that are principally
engaged in the real estate industry. In selecting investments for the Fund, the
Sub-Advisers will select companies that derive at least 50% of their total
revenues or earnings from owning, operating, developing and/or managing real
estate. This portion of the portfolio will have investments located in at least
three different countries including the United States. As a general matter, the
Fund expects these investments to be in common stocks and real estate investment
trusts of large, mid-sized, and small companies.

     The Sub-Advisers use a disciplined two-step process for constructing the
Fund's portfolio.

     - First, the Sub-Advisers select sectors and geographic regions in which to
       invest, and determine the degree of representation of such sectors and
       regions, through a systematic evaluation of public and private property
       market trends and conditions.

     - Second, the Sub-Advisers use an in-house valuation process to identify
       investments with superior current income and growth potential relative to
       their peers. This in-house valuation process examines several factors
       including: (i) value and property; (ii) capital structure; and (iii)
       management and strategy.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities. In addition, when interest rates
       increase, the value of income producing equity securities may decrease,
       and when interest rates decrease, the value of income producing equity
       securities may increase.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources,
<PAGE>   27
 24                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

       narrower product lines and less depth of management. The securities of
       mid-sized companies may be subject to more volatile market movements than
       securities of larger, more established growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. Rather, the market could favor
       stocks in industries to which the Fund is not exposed, or may not favor
       equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to a particular industry, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives.

     - Real Estate Risk.  Investments in issuers that are principally engaged in
       real estate, including real estate investment trusts ("REITs"), may
       subject the Fund to risks similar to those associated with the direct
       ownership of real estate (in addition to securities market risks). These
       companies are sensitive to factors such as changes in real estate values
       and property taxes, interest rates, cash flow of underlying real estate
       assets, supply and demand, and the management skill and creditworthiness
       of the issuer. REITs may also be affected by tax and regulatory
       requirements.

 ING QUALITY OF LIFE FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of U.S. and non-U.S. quality of life
companies. The Fund defines quality of life companies as those companies that
derive at least 50% of their total revenues or earnings from offering products
and services helping persons live longer, healthier and happier lives. Such
companies may include, but will not be limited to, companies engaged in the
research, development, production or distribution of products or services
related to health care (for example, pharmaceutical and consumer goods
companies, biotechnology companies, and health maintenance organization
companies); companies engaged in providing entertainment services or equipment
related to leisure time activities (for example, travel and leisure companies
and sports equipment companies); and companies providing other services or
products desired by the aging baby boomer population (for example, retirement
community development companies). As a general matter, the Fund expects these
investments to be in common stocks of large companies whose market
capitalizations are generally in excess of $10 billion.

     The Sub-Adviser believes that quality of life companies will benefit from
the aging baby boomer generation. The global consumption pattern is steadily
changing as a result of an increase in wealth and a resulting increase in life
expectancy. Especially in the developed countries, the population is rapidly
aging. In the opinion of the Sub-Adviser this development will lend to a
structural increase in healthcare spending. At the same time the growing group
of aging people will have an increasing need for various services and more and
new possibilities of leisure activities. People will be increasingly willing to
invest in their quality of life aiming at longer, healthier and happier lives.

     In choosing investments for the Fund, the Sub-Adviser first identifies
themes which it believes will drive the healthcare, leisure and other industries
benefiting from the aging baby boomer generation. Then, by conducting extensive
fundamental research, the Sub-Adviser analyzes individual companies worldwide to
identify those firms that

- --------------------------------------------------------------------------------

are most likely to benefit from the selected investment themes.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in industries to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.

       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to particular industries, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives. Swings in
       investor psychology or significant trading by large institutional
       investors can result in significant price fluctuations and stock price
       declines.

                              PRICING ALTERNATIVES

     The Funds offer a choice of five share classes, each with its own sales
load and expense structure, allowing you to invest in the way that best suits
your needs. Class A, Class B and Class C shares are offered in this Prospectus.
Class X and Class I shares are offered under separate prospectuses. The Class X
shares has different sales charges and other expenses, which may affect
performance, and may be purchased only by certain qualified investors
(including, but not limited to, IRAs, Roth IRAs, SEP IRAs, Simple IRAs and
403(b)(7) plans). The Class I shares are sold without an initial sales charge
and also are not subject to any Rule 12b-1 fees, shareholder servicing fees or
account servicing fees. The Class I shares may be purchased only by (i)
retirement plans affiliated with ING Group, and (ii) ING Group and its
affiliates for purposes of corporate cash management. Each share class
represents an ownership interest in the same investment portfolio. When you
choose your class of shares you should consider the size of your investment and
how long you plan to hold your shares.

     For example, if you select Class A shares, you generally pay a sales load
at the time of purchase. If you buy Class A shares, you will also be subject to
a distribution fee of 0.50% and a shareholder servicing fee of 0.25%. You may be
eligible for a sales load reduction or waiver.

     If you select Class B or C shares, you will invest the full amount of your
purchase price, but you will be subject to a distribution fee of 0.75% and a
shareholder servicing fee of 0.25%. Because these fees are paid out of the
Fund's assets on an ongoing basis, over time these fees increase the cost of
your investment and may cost you more than purchasing the Class A shares and
paying an initial sales load. In addition, you may be subject to a deferred
sales load when you sell Class B or Class C shares.

     The Funds' shares are distributed by ING Funds Distributor, Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Funds' shares may be
sold by retail broker-dealers that are under common control with the Funds. As
of the date of this Prospectus, such broker-dealers are Compulife Investor
Services, Inc., IFG Network Securities, Inc., Locust Street Securities, Inc.,
Multi-Financial Securities Corporation, VESTAX Securities Corporation, ING
Barings Furman Selz LLC and ING Barings LLC.

     No initial sales load is applied to Class A shares of any Fund that you
purchase through the reinvestment of dividends or distributions.

     A reduced or waived sales load on a purchase of Class A shares may apply
for purchases under a "Right of Accumulation" or "Letter of Intent." The Right
of Accumulation permits you to pay the sales load that would apply to the cost
or value (whichever is higher) of all shares you own in the ING Funds at the
time of your current purchase. A Letter of Intent permits you to pay the sales
load that would be applicable if you add up all shares of the ING Funds that you
agree to buy within a 13-month period. Of the Letter of Intent amount, 5% will
be held in escrow to cover additional sales charges which may be due if your
total investments over the 13 month period are not sufficient to qualify for a
sales charge reduction. Certain restrictions

apply. In order for the sales charge reductions to be effective under either of
these programs, the Transfer Agent must be notified of the reduction request
when the purchase order is placed. Additional information concerning these
programs can be obtained from the Funds by calling 1-877-INFO-ING.

     With regard to Funds that charge an initial sales load, the initial sales
load on Class A shares is waived with respect to the following types of
investments:

     - Purchases by the Investment Manager, ING Group or any affiliated company,
       including employee benefit plans established by any such entity.

     - Purchases by officers, directors, trustees and employees of the Funds,
       the Investment Manager and their affiliates, including members of the
       immediate families of such individuals.

     - Purchases by broker-dealers who have a sales agreement with the
       Distributor and their registered personnel and employees, including
       members of the immediate families of such registered personnel and
       employees.

     - Purchases by clients of broker-dealers, investment advisers, third-party
       administrators or consultants that have entered into an agreement with
       the Distributor providing for the use of Fund shares in investment
       products or services made available to their clients.

     - Purchases by employees of firms providing the Funds or their affiliates
       with legal, administrative, marketing or other services, including
       members of the immediate families of such individuals.

     - Purchases paid for with the proceeds of shares redeemed in the prior 180
       days from another mutual fund on which an initial sales load or CDSL was
       paid.

     - Purchases by 401(k) plans and other defined contribution plans with at
       least 25 eligible employees; 403(b)(7) or 457 plans under ERISA; and
       non-qualified deferred compensation plans.

     - Purchases constituting loan repayments by a retirement plan participant.

     - Purchases by former participants in a qualified retirement plan, where a
       portion of the plan was invested in the Funds.

     - Purchases under arrangements between the Distributor and organizations
       which make recommendations to or permit group solicitations of its
       employees, members or participants.

     If you redeem Class A shares and within 90 days buy new shares of the same
class, you will not pay a sales load on the new purchase amount and you will
receive a credit for any CDSL paid. If such reinstated shares are then redeemed
within one year of the initial purchase, the CDSL will be imposed upon the
redemption. The amount eligible for this "Reinstatement Privilege" may not
exceed the amount of your redemption proceeds. To exercise the privilege,
contact the Funds at 1-877-INFO-ING.

 CLASS B SHARES -- DEFERRED SALES LOAD ALTERNATIVE

     If you select Class B shares, you do not pay an initial sales load at the
time of purchase. However, if you redeem your Class B shares within 6 years
after purchase, you may be required to pay a deferred sales load. You will also
pay distribution fees of 0.75% and shareholder servicing fees of 0.25% each
year. Because these fees are paid out of a Fund's assets on an ongoing basis,
over time these fees increase the cost of your investment and may cost you more
than purchasing the Class A shares and paying an initial sales load. The
Distributor uses the money that it receives from the deferred sales loads and
the distribution fees to cover the costs of marketing, advertising and
compensating the securities dealer who assists you in purchasing Fund shares.
Although Class B shares are sold without an initial sales load, the Distributor
normally pays a sales commission of 4.00% of the purchase price of Class B
shares to the dealer from its own resources at the time of sale.

     If you redeem Class B shares within 6 years after purchase, you may be
charged a deferred sales load. The amount of the load gradually decreases as you
hold your shares over time, according to the following schedule:

<TABLE>
<CAPTION>
REDEMPTION DURING                          SALES LOAD*

<S>                                        <C>

5th year after purchase..................       2%
6th year after purchase..................       1%
Thereafter...............................     NONE
</TABLE>

- ------------------------------

*   The sales load will apply to the lesser of the original cost of the shares
    being redeemed or the proceeds of your redemption. Shares acquired through
    reinvestment of dividends or distributions are not subject to a deferred
    sales load.

     The deferred sales load relating to Class B shares will be waived in
certain circumstances, such as:

     - Mandated minimum post-retirement withdrawals from an IRA or other
       retirement plan if you are over 59 1/2 years old.

     - Redemptions resulting from shareholder death or disability as long as the
       waiver request is made within one year of death or disability or, if
       later, reasonably promptly following completion of probate.

- --------------------------------------------------------------------------------

     - Redemptions through the Systematic Withdrawal Plan of up to 10% per year
       of the initial account balance, which must be at least equal to $20,000.

     - Redemptions resulting from closure by the Fund of the account in which
       shares are held.

     To determine whether the Class B CDSL applies to a redemption, the Fund
redeems shares in the following order: (i) shares acquired by reinvestment of
dividends and capital gains distributions; (ii) shares held for over six years;
and (iii) shares in the order they were purchased (such that shares held the
longest are redeemed first). In the table above, a "year" is a 12 month period.
All purchases are considered to have been made on the business day of the month
in which the purchase was made.

     Your Class B shares convert automatically into Class A shares eight years
after purchase. Any Class B shares received through reinvestment of dividends or
distributions paid on converting shares will also convert at that time. Class A
shares are subject to lower annual expenses than Class B shares. The conversion
of Class B shares to Class A shares is not a taxable event for federal income
tax purposes.

     If you redeem Class B shares and within 90 days buy new shares of the same
class, you will receive a credit for any CDSL paid. If such reinstated shares
are then redeemed within six years of the initial purchase, the CDSL will be
imposed upon the redemption. The amount eligible for this "Reinstatement
Privilege" may not exceed the amount of your redemption proceeds. To exercise
the privilege, contact the Funds at 1-877-INFO-ING.

 CLASS C SHARES -- LEVEL SALES LOAD ALTERNATIVE

     If you select Class C shares, you do not pay an initial sales load at the
time of purchase. However, if you redeem your Class C shares within one year
after purchase, you may be required to pay a deferred sales load. You will also
pay distribution fees of 0.75% and shareholder servicing fees of 0.25% each
year. Because these fees are paid out of a Fund's assets on an ongoing basis,
over time these fees increase the cost of your investment and may cost you more
than purchasing the Class A shares and paying an initial sales load. The
Distributor uses the money that it receives from the deferred sales loads and
the distribution fees to cover the costs of marketing, advertising and
compensating the securities dealer who assists you in purchasing Fund shares.
Although Class C shares are sold without an initial sales load, the Distributor
normally pays a sales commission of 1.00% of the purchase price of Class C
shares to the dealer from its own resources at the time of sale.

     If you redeem Class C shares within one year after purchase, you may be
charged a deferred sales load of 1.00%. The charge will apply to the lesser of
the original cost of the shares being redeemed or the proceeds of your
redemption. You will not be charged a deferred sales load when you redeem shares
that you acquire through reinvestment of Fund dividends or distributions. The
deferred sales load relating to Class C shares will be reduced or waived in the
same circumstances as described for Class B shares above.

     Class C shares do not offer a conversion privilege.

     If you redeem Class C shares and within 90 days buy new shares of the same
class, you will receive a credit for any CDSL paid. If such reinstated shares
are then redeemed within one year of the initial purchase, the CDSL will be
imposed upon the redemption. The amount eligible for this "Reinstatement
Privilege" may not exceed the amount of your redemption proceeds. To exercise
the privilege, contact the Funds at 1-877-INFO-ING.

                             HOW TO PURCHASE SHARES

     Orders for the purchase of shares of the Funds will be executed at the net
asset value per share plus any applicable sales load ("the public offering
price") next determined after an order has been received. The public offering
price of each Fund is determined as of the close of regular trading on the New
York Stock Exchange (normally 4 p.m. Eastern time) on each day the Exchange is
open for business.

     The minimum initial investment in a Fund is $2,000 ($1,000 for an IRA
investment or any qualified plan). Any subsequent investments must be at least
$50, including an IRA or qualified plan investment. The Distributor may waive
these minimums from time to time. All initial investments should be accompanied
by a completed Account Application. An Account Application accompanies this
Prospectus. A separate application is required for an IRA or qualified plan
investor. All funds received are invested in full and fractional shares of the
appropriate Fund. Certificates for shares are not issued. Shares of the Funds
may be purchased by investors for retirement and non-retirement accounts.

     When you purchase shares of a Fund, please specify the class of shares
that you wish to purchase. If you do not choose a class of shares, then your
investment will be made in Class A shares. The Funds reserve the right to
reject any purchase order. The Funds will accept third party checks from
qualified financial institutions, such as broker-dealers and investment
advisers that are registered with the Securities and Exchange Commission, as
well as insurance companies,

     IRA investments made through the ING Auto-Asset Accumulation Plan or Direct
Deposit Plans will be treated as current year contributions only. Prior year
contributions through the ING Auto-Asset Accumulation Plan or Direct Deposit
Plans are prohibited. IRA investments cannot exceed Internal Revenue Service
stated maximums for investing in a calendar year. It is the account holder's
responsibility to ensure that their account(s) are within these maximum
investment guidelines.

                              HOW TO REDEEM SHARES

     You may redeem your shares, in whole or in part, on each day a Fund is
valued. Shares will be redeemed without charge (except for any applicable CDSL)
at the net asset value next determined after a redemption request in good order
has been received by the Funds. In the instance where you own more than one
class of shares and the class of shares being redeemed are not subject to the
CDSL, those shares with the highest Rule 12b-1 fee will be redeemed in full
prior to any redemption of shares with a lower Rule 12b-1 fee.

     When purchases are made by check in any Fund, redemption proceeds will be
made available immediately upon clearance of the purchase check, which may take
up to 15 calendar days. You may avoid this delay by investing through wire
transfers of federal funds.

     Once your shares are redeemed, the Funds will ordinarily send the proceeds
by check to you at the address of record on the next business day. To ensure
acceptance of your redemption request, it is important to follow the procedures
described below. If you purchased your shares through an Authorized Broker or
Investment Adviser, please contact them to inquire which redemption methods are
available to you. Under certain circumstances described below, a signature
guarantee may be required. You may redeem your shares using any of the following
methods:

  Optional Insurance Benefit      Insurance companies, including certain companies
                                  affiliated with the Manager, may make certain life
                                  insurance coverage available to persons on whose behalf
                                  shares of the Funds are purchased. The benefits of this
                                  coverage payable at death will be related to the amounts
                                  paid to purchase shares and to the value of the shares
                                  held for the benefit of the insured persons. If you
                                  purchase such life insurance coverage, you will be
                                  required to authorize periodic redemptions of Fund shares
                                  to pay the premiums for such coverage. These redemptions
                                  will not be subject to CDSLs, but will have the same tax
                                  consequences as any other Fund redemptions. Certain
                                  restrictions apply. Call 1-877-INFO-ING for more
                                  information and application forms for this program.

     The Funds reserve the right to redeem in kind. That is, the Funds may honor
redemption requests with readily marketable portfolio securities instead of cash
if during any 90-day period redemptions exceed the lesser of $250,000 or 1% of
the net assets of the redeeming Fund at the beginning of such period. You may
incur transaction costs associated with converting these securities to cash.

     Due to the high costs of maintaining small accounts, the Funds may ask that
you increase your account balance if (1) the value of your account falls below
$500 for three consecutive months as a result of redemptions or exchanges, and
(2) your account has been in existence for at least one year and you have not
made any additional purchases in the account within the preceding six calendar
months. If the account balance remains below the minimum requirement for 60 days
after you are notified, the Funds may close your account and send you the
redemption proceeds.

     Signature Guarantees.  A signature guarantee is designed to protect the
investor, the Funds and their agents by verifying the signature of certain
investors seeking to redeem, transfer, or exchange shares of the Funds.
Signature guarantees are required for:

     - redemptions by mail in excess of $50,000;

     - redemptions by mail if the proceeds are to be paid to someone other than
       the name(s) in which the account is registered;

     - redemptions requesting proceeds to be sent by wire to other than the bank
       of record for the account;

     - redemptions requesting proceeds to be sent to a new address or an address
       that has been changed within the past 15 days;

     - requests to transfer the registration of shares to another owner;

     - telephone exchange and telephone redemption authorization forms;

     - changes in previously designated wiring instructions; or

     - redemptions or exchanges of shares previously reported as lost/abandoned
       property, whether or not the redemption amount is under $50,000 or the
       proceeds are to be sent to the address of record.

     The foregoing requirements may be waived or modified upon notice to
shareholders.

     Acceptable guarantors include banks, broker-dealers, credit unions,
national securities exchanges, savings associations and any other organization,
provided that such institution or organization qualifies as an "eligible
guarantor institution" as that term is defined in rules adopted by the
Securities and Exchange Commission. For information regarding whether a
particular institution or organization qualifies as an "eligible guarantor
institution," contact the Funds at 1-877-INFO-ING.

                               EXCHANGE PRIVILEGE

     Except as described below, Class A shares of any Fund may be exchanged for
Class A shares of any other Fund. Any sales load previously paid on the shares
being exchanged will be credited toward the sales load payable on the shares
being acquired.

     Except as described below, Class B shares and Class C shares of a Fund, as
well as Class A shares subject to a contingent deferred sales load, may be
exchanged, based on the per share net asset values, for the same class of shares
of any other Fund. You will receive credit for the period of time you held the
shares being exchanged when determining whether the acquired shares, when
redeemed, will be subject to a contingent deferred sales load.

     Your exchange will be processed at the next determined net asset value (or
offering price, if there is a sales load) after the Funds receive your request.
A new account opened by exchange must be established with the same name(s),
address and social security number as the existing account.

- --------------------------------------------------------------------------------

                               PRICING OF SHARES

     Each of the Funds prices its shares based on its net asset value. The Funds
value portfolio securities for which market quotations are readily available at
market price. These Funds value 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 Funds may value the security at its fair value as determined
in good faith by or under the supervision of the Board of Trustees. The effect
of using fair value pricing is that a Fund's net asset value will be subject to
the judgment of the Board of Trustees or its designee instead of being
determined by the market. Because some of the Funds may invest in securities
that are primarily listed on foreign exchanges, the value of those Funds' shares
may change on days when you will not be able to purchase or redeem shares.

     Each Fund determines the net asset value of its shares as of the close of
the NYSE (normally 4:00 p.m., Eastern time) on each day the NYSE is open for
business. The price at which a purchase or redemption is effected is based on
the next calculation of a Fund's net asset value after the order is placed.

                          DIVIDENDS AND DISTRIBUTIONS

     Each Fund intends to distribute to its shareholders substantially all of
its investment company taxable income (which includes dividends and interest and
the excess, if any, of net short-term capital gains over net long-term capital
losses). Each of the Funds will declare and pay these dividends annually, except
for the ING Growth & Income Fund, ING Global Real Estate Fund and the ING
Balanced Fund, which will declare and pay dividends quarterly. In addition, each
Fund intends to distribute, at least annually, substantially all of its net
capital gains (the excess of net long-term capital gains over net short-term
capital losses). In determining amounts of capital gains to be distributed, any
capital loss carryovers from prior years will be applied against capital gains.

     Dividends and distributions will be reinvested in additional shares of a
Fund at net asset value unless you elect to receive such dividends and
distributions in cash. If you redeem all or a portion of Fund shares prior to a
dividend payment date, you will be entitled on the next dividend payment date to
all dividends declared but unpaid on those shares at the time of their
redemption.

     If you elect to receive distributions in cash and the post office cannot
deliver your checks or if you do not cash your checks within six months, your
dividends may be reinvested in your account at the then-current net asset value
and your account will be converted to the reinvestment option. You will not
receive interest on the amount of your uncashed checks.

     You may also elect to automatically invest dividends and distributions paid
by a Fund in shares of any other ING Fund of which you are a shareholder. Shares
of the other Fund will be purchased at that Fund's then-current net asset value.

     You may also elect to transfer electronically dividends and distributions
paid by a Fund to your designated bank account if your financial institution is
an Automated Clearing House member. Banks may charge a fee for the service.

     The elections described above may be made either on the Account Application
or by calling the Fund at 1-877-INFO-ING.

                                     TAXES

     Each Fund is treated as a separate entity for federal income tax purposes.
Each Fund intends to qualify as a regulated investment company by satisfying the
requirements under Subchapter M of the Internal Revenue Code of 1986 (the
"Code"), including requirements with respect to diversification of assets,
distribution of income and sources of income. By so qualifying, each Fund
generally will not be subject to federal income tax to the extent that it
distributes investment company taxable income and net realized capital gains in
the manner required under the Code.

     Distributions by a Fund of its taxable net investment income and the
excess, if any, of its net short-term capital gain over its net long-term
capital loss are taxable to shareholders as ordinary income. Such distributions
are treated as dividends for federal income tax purposes but may qualify for the
70% dividends-received deduction for corporate shareholders. Distributions by a
Fund of the excess, if any, of its net long-term capital gain over its net
short-term capital loss are designated as capital gain dividends and are taxable
as long-term capital gains, regardless of the length of time you have held your
shares.

     Distributions will be treated in the same manner for federal income tax
purposes whether you receive them in cash or reinvest them in additional shares
of the Fund. In

- --------------------------------------------------------------------------------

general, distributions by a Fund are taxable to you in the year in which the
distributions are made. However, certain distributions made during January will
be treated as having been paid by a Fund and received by you on December 31 of
the preceding year.

     Investment income received by a Fund from sources within foreign countries
may be subject to foreign income taxes withheld at the source. To the extent any
Fund is liable for foreign income taxes withheld at the source, each Fund
intends, if possible, to operate so as to meet the requirements of the Code to
"pass through" to the Fund's shareholders credits for foreign income taxes paid,
but there can be no assurance that any Fund will be able to do so.

     A redemption or an exchange of shares is a taxable transaction on which you
may realize a gain or loss. Any gain or loss realized upon the sale or other
disposition of shares of a Fund generally will be a capital gain or loss which
will be long-term or short-term depending on how long you have held the shares.
Any loss realized upon a sale or disposition of shares within six months from
the date of their purchase will be treated as a long-term capital loss to the
extent of any capital gain distributions received on such shares.

     Under the backup withholding rules of the Code, you may be subject to 31%
withholding of federal income tax on ordinary income dividends paid by a Fund.
In order to avoid this backup withholding, you must provide the Funds with a
correct taxpayer identification number or certify that you are otherwise exempt
from or not subject to backup withholding.

     You will be notified annually as to the federal tax status of distributions
made by the Funds in which you invest. Depending on your residence for tax
purposes, distributions also may be subject to state and local taxes. You should

                  MORE INFORMATION ABOUT STRATEGIES AND RISKS

     A Fund's risk profile is largely a factor of the principal securities in
which it invests and investment techniques that it uses. The following pages
discuss the risks associated with certain of the types of securities in which
the Funds may invest and certain of the investment practices that the Funds may
use. For more information about these and other types of securities and
investment techniques used by the Funds, see the Statement of Additional
Information. Unless indicated otherwise, the following descriptions apply to all
Funds.

     Many of the investment techniques and strategies discussed in this
Prospectus and in the Statement of Additional Information are discretionary,
which means that the Investment Manager or Sub-Adviser can decide whether to use
them or not. The Investment Manager or Sub-Adviser may also use investment
techniques or make investments in securities that are not a part of the Fund's
principal investment strategy.

     Temporary Defensive Strategies (All Funds).  When the Investment Manager or
Sub-Adviser to a Fund anticipates unusual market or other conditions, the Fund
may temporarily depart from its principal investment strategies. Under such
circumstances, up to 100% of the Fund's assets may be invested in investment
grade fixed income securities (for example, rated at least BBB by Standard &
Poor's Rating Group or Baa by Moody's Investor Services), money market
securities, certificates of deposit, bankers' acceptances, commercial paper or
in any other securities which in either the Investment Manager's or
Sub-Adviser's opinion are more conservative than the types of securities in
which the Fund typically invests. To the extent a Fund is engaged in temporary
defensive investments, it will not be pursuing its investment objective.

     Investments in Foreign Securities (All Funds).  There are certain risks in
owning foreign securities, including those resulting from: fluctuations in
currency exchange rates; devaluation of currencies; political or economic
developments and the possible imposition of currency exchange blockages or other
foreign governmental laws or restrictions; reduced availability of public
information concerning issuers; accounting, auditing and financial reporting
standards or other regulatory practices and requirements that are not uniform
when compared to those applicable to domestic companies; settlement and
clearance procedures in some countries that may not be reliable and can result
in delays in settlement; higher transaction and custody expenses than for
domestic securities; and limitations on foreign ownership of equity securities.
Also, securities of many foreign companies may be less liquid and the prices
more volatile than those of domestic companies. With certain foreign countries,
there is the possibility of expropriation, nationalization, confiscatory
taxation and limitations on the use or removal of funds or other assets of the
Funds, including the withholding of dividends.

     Each Fund that invests in foreign securities may enter into foreign
currency transactions either on a spot or cash basis at prevailing rates or
through forward foreign currency exchange contracts in order to have the
necessary currencies to settle transactions or to help protect the Fund against
adverse changes in foreign currency exchange rates. Such efforts could limit
potential gains that might result from a relative increase in the value of such
currencies, and might, in certain cases, result in losses to the Fund.

- --------------------------------------------------------------------------------

     Emerging Market Investments (ING International Equity Fund and ING Emerging
Markets Equity Fund).  Because of less developed markets and economies and, in
some countries, less mature governments and governmental institutions, the risks
of investing in foreign securities can be intensified in the case of investments
in issuers domiciled or doing substantial business in emerging market countries.
These risks include: high concentration of market capitalization and trading
volume in a small number of issuers representing a limited number of industries,
as well as a high concentration of investors and financial intermediaries;
political and social uncertainties; over-dependence on exports, especially with
respect to primary commodities, making these economies vulnerable to changes in
commodity prices; overburdened infrastructure and obsolete financial systems;
environmental problems; less well developed legal systems; and less reliable
custodial services and settlement practices.

     Corporate and Municipal Debt Securities (All Funds). Corporate debt
securities are subject to the risk of the issuer's inability to meet principal
and interest payments on the obligation and may also be subject to price
volatility due to such factors as interest rate sensitivity, market perception
of the credit-worthiness of the issuer and general market liquidity. When
interest rates decline, the value of the debt securities can be expected to
rise, and when interest rates rise, the value of those securities can be
expected to decline. Debt securities with longer maturities tend to be more
sensitive to interest rate movements than those with shorter maturities.

     Initial Public Offerings (All Funds).  A significant portion of a Fund's
return may be attributable to its investment in initial public offerings. When a
Fund's asset base is small, the impact of such investments on a Fund's return
will be magnified. As the Fund's assets grow, it is probable that the effect of
the Fund's investment in initial public offerings on the Fund's total return
will decline.

     U.S. Government Securities (All Funds).  Some U.S. Government agency
securities may be subject to varying degrees of credit risk, and all U.S.
Government securities may be subject to price declines in the securities due to
changing interest rates.

     Convertible Securities (All Funds).  The price of a convertible security
will normally fluctuate in some proportion to changes in the price of the
underlying equity security, and as such is subject to risks relating to the
activities of the issuer and general market and economic conditions. The income
component of convertible securities causes fluctuations based upon changes in
interest rates and the credit quality of the issuer. Convertible securities are
often lower rated securities. A Fund may be required to redeem or convert a
convertible security before the holder would otherwise choose.

     Other Investment Companies (All Funds).  Each Fund may invest up to 10% of
its assets in other unaffiliated investment companies. There is no limit with
regard to investments in affiliated investment companies. When a Fund invests in
other investment companies, you indirectly pay a proportionate share of the
expenses of that other investment company (including management fees,
administration fees, and custodial fees) in addition to the expenses of the
Fund.

     Restricted and Illiquid Securities (All Funds).  Each Fund may invest up to
15% of its net assets in restricted and illiquid securities. If a security is
illiquid, the Fund might be unable to sell the security at a time when the
sub-adviser might wish to sell, and the security could have the effect of
decreasing the overall level of the Fund's liquidity. Further, the lack of an
established secondary market may make it more difficult to value illiquid
securities, which could vary from the amount the Fund could realize upon
disposition. Restricted securities, i.e., securities subject to legal or
contractual restrictions on resale, may be illiquid. However, some restricted
securities may be treated as liquid, although they may be less liquid than
registered securities traded on established secondary markets.

     Mortgage-Related Securities (All Funds).  Although mortgage loans
underlying a mortgage-backed security may have maturities of up to 30 years, the
actual average life of a mortgage-backed security typically will be
substantially less because the mortgages will be subject to normal principal
amortization, and may be prepaid prior to maturity. Like other fixed income
securities, when interest rates rise, the value of a mortgage-backed security
generally will decline; however, when interest rates are declining, the value of
mortgage-backed securities with prepayment features may not increase as much as
other fixed income securities. The rate of prepayments on underlying mortgages
will affect the price and volatility of a mortgage-related security, and may
have the effect of shortening or extending the effective maturity of the
security beyond what was anticipated at the time of the purchase. Unanticipated
rates of prepayment on underlying mortgages can be expected to increase the
volatility of such securities. In addition, the value of these securities may
fluctuate in response to the market's perception of the creditworthiness of the
issuers of mortgage-related securities owned by a Fund. Additionally, although
mortgages and mortgage-related securities are generally supported by some form
of government or private guarantee and/or insurance, there is no assurance that
private guarantors or insurers will be able to meet their obligations.

     Asset-Backed Securities (All Funds).  Asset-backed securities involve
certain risks that are not posed by mortgage-related securities, resulting
mainly from the fact that asset-backed securities often do not contain the
benefit of a complete security interest in the related collateral. The risks
associated with asset-backed securities may be reduced
<PAGE>   52
ING FUNDS TRUST                                                               49
- --------------------------------------------------------------------------------

by the addition of credit enhancements such as a bank letter of credit or a
third-party guarantee.

     Derivatives (All Funds).  Generally, derivatives can be characterized as
financial instruments whose performance is derived, at least in part, from the
performance of an underlying asset or assets. Some derivatives are sophisticated
instruments that typically involve a small investment of cash relative to the
magnitude of risks assumed. These may include swap agreements, options, forwards
and futures. Derivative securities are subject to market risk, which could be
significant for those that have a leveraging effect. Many of the Funds do not
invest in these types of derivatives, so please check the description of the
Fund's policies found in the Statement of Additional Information. Derivatives
are also subject to credit risks related to the counterparty's ability to
perform, and any deterioration in the counterparty's creditworthiness could
adversely affect the instrument. A risk of using derivatives is that the adviser
might imperfectly judge the market's direction. For instance, if a derivative is
used as a hedge to offset investment risk in another security, the hedge might
not correlate to the market's movements and may have unexpected or undesired
results, such as a loss or a reduction in gains.

     Dollar Roll Transactions (All Funds).  The Funds may enter into dollar roll
transactions wherein the Fund sells fixed income securities, typically
mortgage-backed securities, and makes a commitment to purchase similar, but not
identical, securities at a later date from the same party. Like a forward
commitment, during the roll period no payment is made for the securities
purchased and no interest or principal payments on the security accrue to the
purchaser, but a Fund assumes the risk of ownership. A Fund is compensated for
entering into dollar roll transactions by the difference between the current
sales price and the forward price for the future purchase, as well as by the
interest earned on the cash proceeds of the initial sale. Like other when-issued
securities or firm commitment agreements, dollar roll transactions involve the
risk that the market value of the securities sold by the Funds may decline below
the price at which a Fund is committed to purchase similar securities. In the
event the buyer of securities under a dollar roll transaction becomes insolvent,
the Funds' use of the proceeds of the transaction may be restricted pending a
determination by the other party, or its trustee or receiver, whether to enforce
the Funds' obligation to repurchase the securities.

     Repurchase Agreements (All Funds).  Each Fund may enter into repurchase
agreements, which involve the purchase by a Fund of a security that the seller
has agreed to buy back. If the seller defaults and the collateral value
declines, the Fund might incur a loss. If the seller declares bankruptcy, the
Fund may not be able to sell the collateral at the desired time.

     Lending Portfolio Securities (All Funds).  In order to generate additional
income, each Fund may lend portfolio securities in an amount up to 33 1/3% of
its total assets to broker-dealers, major banks, or other recognized domestic
institutional borrowers of securities. As with other extensions of credit, there
are risks of delay in recovery or even loss of rights in the collateral should
the borrower default or fail financially.

     Borrowing (All Funds).  Each Fund may borrow for certain types of temporary
or emergency purposes subject to certain limits. Borrowing may exaggerate the
effect of any increase or decrease in the value of portfolio securities or the
net asset value of a Fund, and money borrowed will be subject to interest costs.
Interest costs on borrowings may fluctuate with changing market rates of
interest and may partially offset or exceed the return earned on borrowed funds.
Under adverse market conditions, a Fund might have to sell portfolio securities
to meet interest or principal payments at a time when fundamental investment
considerations would not favor such sales.

     Reverse Repurchase Agreements (All Funds).  A reverse repurchase agreement
involves the sale of a security, with an agreement to repurchase the same
securities at an agreed upon price and date. Whether such a transaction produces
a gain for a Fund depends upon the costs of the agreements and the income and
gains of the securities purchased with the proceeds received from the sale of
the security. If the income and gains on the securities purchased fail to exceed
the costs, net asset value will decline faster than otherwise would be the case.
Reverse repurchase agreements, as leveraging techniques, may increase a Fund's
yield; however, such transactions may result in a shareholder's loss of
principal.

     Short Sales (ING International Equity Fund and ING Emerging Markets Equity
Fund).  A "short sale" is the sale by a Fund of a security which has been
borrowed from a third party on the expectation that the market price will drop.
If the price of the security rises, the Fund may have to cover its short
position at a higher price than the short sale price, resulting in a loss.

     Investments in Small- and Mid-Capitalization Companies (All Funds).  The
Funds may invest in small and mid capitalization companies. Investments in mid-
and small-capitalization companies involve greater risk than is customarily
associated with larger, more established companies due to the greater business
risks of small size, limited markets and financial resources, narrow product
lines and the frequent lack of depth of management. The securities of smaller
companies are often traded over-the-counter and may not be traded in volumes
typical on a national securities exchange. Consequently, the securities of
smaller companies may have limited market stability and may be subject to more
abrupt or erratic market movements

- --------------------------------------------------------------------------------

than securities of larger, more established growth companies or the market
averages in general.

     Non-diversified Investment Companies (ING Global Brand Names Funds, ING
Focus Fund, ING Global Real Estate Fund, ING Internet Fund, ING Internet Fund II
and ING Quality of Life Fund).  Certain Funds are classified as non-diversified
investment companies under the 1940 Act, which means that each Fund is not
limited by the 1940 Act in the proportion of its assets that it may invest in
the obligations of a single issuer. The investment of a large percentage of a
Fund's assets in the securities of a small number of issuers may cause that
Fund's share price to fluctuate more than that of a diversified investment
company.

     Concentration (ING Global Information Technology Fund, ING Global
Communications Fund, ING Internet Fund, ING Internet Fund II, ING Global Real
Estate Fund and ING Quality of Life Fund).  Certain Funds "concentrate" (for
purposes of the 1940 Act) their assets in securities related to a particular
sector or industry, which means that at least 25% of its assets will be invested
in these assets at all times. As a result, each Fund may be subject to greater
market fluctuation than a fund which has securities representing a broader range
of investment alternatives.

     Fundamental and Non-Fundamental Policies (All Funds).  Unless otherwise
stated, all investment objectives and policies are non-fundamental and may be
amended without shareholder approval.

     Percentage Investment Limitations (All Funds).  Unless otherwise stated,
percentage limitations in this prospectus apply at the time of investment.

     Portfolio Turnover (All Funds).  Each Fund may engage in frequent and
active trading of portfolio securities to achieve its investment objective. A
high portfolio turnover rate involves greater expenses to a Fund, including
brokerage commissions and other transaction costs, and is likely to generate
more taxable short-term gains for shareholders, which may have an adverse effect
on the performance of the Fund.

                               FUNDS AT A GLANCE

 ING INTERMEDIATE BOND FUND

     Investment Objective.  A high level of current income consistent with the
preservation of capital and liquidity.

     Main Investments.  A diversified portfolio of debt securities, with a
minimum average portfolio quality being investment grade, as discussed herein,
and a dollar-weighted average maturity generally ranging between three and ten
years.

     Main Risks.  You could lose money. Other risks include price volatility and
risks, as discussed herein, related to investments in fixed income securities,
including sensitivity to interest rate fluctuations. Investor demand, changes in
the financial condition of issuers of securities, and general economic
conditions, among other factors, may affect the market value and yield of the
Fund's securities.

 ING HIGH YIELD BOND FUND

     Investment Objective.  A high level of current income and total return.

     Main Investments.  A diversified portfolio of high yield (high risk) debt
securities that are unrated or rated below investment grade, as discussed
herein.

     Main Risks.  You could lose money. Other risks include price volatility and
risks, as discussed herein, related to investments in fixed income securities,
including sensitivity to interest rate fluctuations. Lower-rated securities may
be subject to wider fluctuations in yield and market value than higher-rated
securities. The market for high yield securities may be less liquid than the
markets for higher-rated securities, which may have an adverse effect on the
market value of certain securities.

 ING INTERNATIONAL BOND FUND

     Investment Objective.  High total return.

     Main Investments.  A non-diversified portfolio of investment grade debt
securities of issuers located throughout the world, not including the United
States.

     Main Risks.  You could lose money. Other risks include price volatility and
risks, as discussed herein, related to investments in fixed income securities,
including sensitivity to interest rate fluctuations, and maintaining a
non-diversified portfolio. The Fund also will experience risks related to
investments in foreign securities (for example, currency exchange rate
fluctuations).

 ING MORTGAGE INCOME FUND

     Investment Objective.  Long-term income consistent with the preservation of
capital.

     Main Investments.  A diversified portfolio of mortgage-backed securities
rated at least "A" or the equivalent.

     Main Risks.  You could lose money. Other risks include price volatility and
risks, as discussed herein, related to investments in fixed income securities,
including sensitivity to interest rate fluctuations. The Fund's mortgage-backed
securities also will be subject to prepayment risk, which is the risk that the
principal on the underlying mortgage loans may be prepaid at any time, and
extension risk, which is the risk that an unexpected rise in interest rates will
extend the life of a mortgage-backed security beyond the expected prepayment
time.

 ING NATIONAL TAX-EXEMPT BOND FUND

     Investment Objective.  A high level of current income that is exempt from
federal income taxes, consistent with the preservation of capital.

     Main Investments.  A diversified portfolio of investment grade debt
securities of municipal issuers, the interest from which is exempt from federal
income taxes.

     Main Risks.  You could lose money. Other risks include price volatility and
risks, as discussed herein, related to investments in fixed income securities,
including sensitivity to interest rate fluctuations. Investor demand, changes in
the financial condition of issuers of securities, and general economic
conditions, among other factors, may affect the market value and yield of the
Fund's securities.

 ING STABLE VALUE FUND

     Investment Objective.  A higher level of current income than that of a
money market fund, while seeking to preserve capital and maintain a stable net
asset value per share.

     Main Investments.  A diversified portfolio of debt securities, with a
minimum average portfolio quality of at least "A" and a dollar-weighted average
duration generally ranging between two and one-half years and four and one-half
years.

     Main Risks.  You could lose money. Other risks include price volatility and
risks, as discussed herein, related to investments in fixed income securities,
including sensitivity to interest rate fluctuations. Although the Fund will
enter into wrapper agreements with highly rated financial institutions, such as
banks or insurance companies, which are utilized to stabilize the net asset
value of the Fund, there is no assurance that the Fund will be able to maintain
a perfectly stable net asset value.

                                   BOND FUNDS

 ING INTERMEDIATE BOND FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income consistent with the preservation of capital and
liquidity.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of debt securities which, at the time of investment, are rated
investment grade (for example, rated at least BBB by Standard & Poor's Rating
Group or Baa by Moody's Investor Services) or have an equivalent rating by a
nationally recognized statistical rating organization, or of comparable quality
if unrated. Although the Fund may invest a portion of its assets in high yield
(high risk) debt securities rated below investment grade, the Fund will seek to
maintain a minimum average portfolio quality rating of at least investment
grade. The dollar-weighted average maturity of the Fund will generally range
between three and ten years.

     The Fund may invest the remainder of its assets in: convertible securities
and preferred stocks; U.S. Government securities, securities of foreign
governments and supranational organizations, and high-quality money market
instruments that the Sub-Adviser believes are appropriate in light of the Fund's
investment objective; municipal bonds, notes and commercial paper; and debt
securities of foreign issuers. The Fund may purchase structured debt obligations
and may engage in dollar roll transactions and swap agreements. The Fund may
also sell securities short and may use options and futures contracts involving
securities, securities indices and interest rates. A portion of the Fund's
assets may be invested in mortgage-backed securities and asset-backed debt
securities.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, five step investment process which uses fundamental economic and
market research to identify bond market sectors and individual securities
expected to provide above-average returns. The five steps are:

     - First, the Sub-Adviser examines the sensitivity to interest rate
       movements of the portfolio and of the specific holdings of the portfolio
       to position the Fund in a way that attempts to maximize return while
       minimizing volatility.

     - Second, the Sub-Adviser reviews yields relative to maturity and risk of
       bonds to determine the risk/reward characteristics of bonds of different
       maturity classes.

     - Third, the Sub-Adviser identifies sectors that offer attractive value
       relative to other sectors.

     - Fourth, the Sub-Adviser selects securities within identified sectors that
       offer attractive value relative to other securities within their sectors.

     - Finally, the Sub-Adviser seeks trading opportunities to take advantage of
       market inefficiencies to purchase bonds at prices below their calculated
       value.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

       Interest Rate Risk -- In general, when interest rates go up, prices of
       fixed income securities go down. Securities with longer maturities are
       subject to greater fluctuations in value than securities with shorter
       maturities.

       Spread Risk -- The price of a fixed income security is generally
       determined by adding an interest rate spread to a benchmark interest
       rate, such as the U.S. Treasury rate. As the spread on a security widens
       (or increases), the price (or value) of the security falls.

       Default Risk -- An issuer of a security may default on its obligation to
       pay principal and/or interest.

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk. -- An issuer of a security may prepay principal
       earlier than scheduled, which could force the Fund to reinvest in lower
       yielding securities.

       Extension Risk -- Slower than expected principal payments on a
       mortgage-backed or asset-backed security may extend such security's life,
       thereby

ING FUNDS TRUST                                                                3
- --------------------------------------------------------------------------------

       locking in a below-market interest rate, increasing the security's
       duration and reducing the value of the security.

     - Risk of High Yield Bonds.  High yield bonds carry particular market risks
       and may experience greater volatility in market value than investment
       grade bonds. Changes in interest rates, the market's perception of the
       issuers and the creditworthiness of the issuers may significantly affect
       the value of these bonds. Some of these securities may have a structure
       that makes their reaction to interest rates and other factors difficult
       to predict, causing their value to be highly volatile. Certain high yield
       bonds, such as zero coupon, deferred interest and payment-in-kind bonds,
       are issued at deep discounts and may experience greater volatility in
       market value. The secondary market for high yield bonds may be less
       liquid than the markets for higher quality securities and this may have
       an adverse effect on the market values of certain securities.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security, as well as credit risk with
       respect to the counterparty to the derivative instrument. The use of
       derivatives may reduce returns.

 ING HIGH YIELD BOND FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income and total return.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of high yield (high risk) bonds. High yield bonds are debt
securities that are not rated by a nationally recognized statistical rating
organization or are rated below investment grade (for example, rated below BBB
by Standard & Poor's Rating Group or Baa by Moody's Investor Services) or have
an equivalent rating by a nationally recognized statistical rating organization.
The Fund defines high yield bonds to include bank loans, payment-in-kind
securities, fixed, variable, floating rate and deferred interest debt
obligations, zero coupon bonds, mortgage-backed and asset-backed debt
obligations, structured debt obligations and convertible bonds, provided they
are unrated or rated below investment grade. In evaluating the quality of a
particular high yield bond for investment by the Fund, the Sub-Adviser does not
rely exclusively on ratings assigned by the nationally recognized statistical
rating organizations. The Sub-Adviser will utilize a security's credit rating as
simply one indication of an issuer's creditworthiness and will principally rely
upon its own analysis of any security. However, the Sub-Adviser does not have
restrictions on the rating level of the securities in the Fund's portfolio and
may purchase and hold securities in default. There are no restrictions on the
average maturity of the Fund or the maturity of any single investment.
Maturities may very widely depending on the Sub-Adviser's assessment of interest
rate trends and other economic or market factors.

     Any remaining assets may be invested in investment grade debt securities;
common and preferred stocks; U.S.
<PAGE>   66

- --------------------------------------------------------------------------------

Government securities and money market instruments that the Sub-Adviser believes
are appropriate in light of the Fund's investment objectives; and debt
securities of foreign issuers. The Fund may purchase structured debt obligations
and may engage in dollar roll transactions and swap agreements. The Fund may
also use options and futures contracts involving securities, securities indices
and interest rates.

     The Fund will not purchase any common stocks if, after such purchase, more
than 20% of the value of its total assets would be invested in common stocks.
The Fund will invest in common stocks in order to attempt to achieve either a
combination of its primary and secondary objectives, in which case the common
stocks will be dividend-paying, or to achieve its secondary objective, in which
case the common stocks may not pay dividends.

     In choosing investments for the Fund, the Sub-Adviser combines extensive
company and industry research with relative value analysis to identify high
yield bonds expected to provide above-average returns. Relative value analysis
is intended to enhance returns by moving from overvalued to undervalued sectors
of the bond market. The Sub-Adviser's team approach to decision making includes
contributions from individual managers responsible for specific industry
sectors.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security, as well as credit risk with
       respect to the counterparty to the derivative instrument. The use of
       derivatives may reduce returns.

     - Risks of Equity Investments.  Equity securities face market, issuer and
       other risks, and their values may go down, sometimes rapidly and
       unpredictably. Market risk is the risk that securities may decline in
       value due to factors affecting securities markets generally or particular
       industries. Issuer risk is the risk that the value of a security may
       decline for reasons relating to the issuer, such as changes in the
       financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

 ING INTERNATIONAL BOND FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of fixed income securities of international issuers which,
at the time of investment, are rated investment grade (for example, rated at
least BBB by Standard & Poor's Rating Group or Baa by Moody's Investor Services)
or have an equivalent rating by a nationally recognized statistical rating
organization, or of comparable quality if unrated. This portion of the portfolio
will have investments in at least three different countries outside of the
United States. There are no restrictions on the average maturity of the Fund or
the maturity of any single investment. Maturities may vary widely depending on
the Sub-Advisers' assessment of interest rate trends and other economic or
market factors. Fixed income securities eligible for purchase by the Fund
consist of:

     - securities issued or guaranteed by foreign governments, their political
       subdivisions, agencies or instrumentalities;

     - corporate bonds and debentures rated investment grade (for example, rated
       at least BBB by Standard & Poor's Rating Group or Baa by Moody's Investor
       Services);

     - obligations of supranational entities;

     - repurchase agreements involving the foregoing securities;

     - loan participations;

     - short-term commercial paper of U.S. or foreign issuers rated in the
       highest two rating categories by a nationally recognized statistical
       rating organization; and

     - swap agreements.

     Any remaining assets of the Fund may be invested in securities denominated
in U.S. dollars or foreign currencies which are rated below investment grade
(for example, rated below BBB by Standard & Poor's Rating Group or Baa by
Moody's Investor Services) or have an equivalent rating by a nationally
recognized statistical rating organization, or of comparable quality if unrated;
U.S. Government securities; obligations of commercial banks, savings and loan
institutions, and U.S. and foreign branches of foreign banks that have total
assets of $500 million or more as shown on the last published financial
statements at the time of investment; mortgage-backed and asset-backed
securities rated within the three highest rating categories by a nationally
recognized statistical rating organization; receipts; and guaranteed investment
contracts. The Fund may also use options and futures contracts involving
securities, securities indices, interest rates and foreign currencies.

     In choosing investments for the Fund, the Sub-Advisers employ a highly
disciplined, four step investment process that seeks to identify bond market
sectors expected to

- --------------------------------------------------------------------------------

provide high and sustainable real rates of return. The four steps are:

     - First, the Sub-Adviser performs a comprehensive analysis of the relative
       value of bond issuances between countries and of currencies to determine
       the degree of representation of such countries and currencies in the
       Fund's portfolio;

     - Second, country allocations, as well as currency and maturity weightings,
       are reviewed by an independent committee within the Sub-Adviser;

     - Third, the Sub-Adviser selects investments within the selected countries
       and currencies based on comprehensive fundamental analysis; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities and currencies.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

       Interest Rate Risk -- In general, when interest rates go up, prices of
       fixed income securities go down. Securities with longer maturities are
       subject to greater fluctuations in value than securities with shorter
       maturities.

       Spread Risk -- The price of a fixed income security is generally
       determined by adding an interest rate spread to a benchmark interest
       rate, such as the U.S. Treasury rate. As the spread on a security widens
       (or increases), the price (or value) of the security falls.

       Default Risk -- An issuer of a security may default on its obligation to
       pay principal and/or interest.

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk -- An issuer of a security may prepay principal
       earlier than scheduled, which could force the Fund to reinvest in lower
       yielding securities.

       Extension Risk -- Slower than expected principal payments on a
       mortgage-backed or asset-backed security may extend such security's life,
       thereby locking in a below-market interest rate, increasing the
       security's duration and reducing the value of the security.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

annual returns and long-term performance. The Fund's past performance is not an

 ING MORTGAGE INCOME FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
income consistent with the preservation of capital.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in mortgage-backed securities. Mortgage-backed securities are securities that
directly or indirectly represent a participation in, or are secured by and
payable from, mortgage loans secured by real property. There are currently three
basic types of mortgage-backed securities: (i) those issued or guaranteed by the
U.S. Government or one of its agencies or instrumentalities, such as Government
National Mortgage Association ("GNMA"), Federal National Mortgage Association
("FNMA") and Federal Home Loan Mortgage Corporation ("FHLMC"); (ii) those issued
by private issuers that represent an interest in or are collateralized by
mortgage-backed securities issued or guaranteed by the U.S. Government or one of
its agencies or instrumentalities; and (iii) those issued by private issuers
that represent an interest in or are collateralized by whole mortgage loans or
mortgage-backed securities without a government guarantee but usually having
some form of private credit enhancement. The Fund may invest in adjustable rate
and fixed rate mortgage securities. The Fund's investments will be rated, at the
time of investment, "A" or better by a nationally recognized statistical rating
organization, or of comparable quality if unrated.

     Any remaining assets of the Fund may be invested in other types of fixed
income securities, including, but not limited to, U.S. Government securities,
corporate bonds, notes and debentures, asset-backed securities and money market
instruments that the Sub-Adviser believes are appropriate in light of the Fund's
investment objective. The Fund may also use options and futures contracts
involving securities, securities indices and interest rates.

     There are no restrictions on the average maturity of the Fund or on the
maturity of any single instrument. Accordingly, the Fund may vary the proportion
of its holdings in long- and short-term debt securities in order to reflect its
assessment of prospective changes in interest rates even if such action may
adversely affect current income. For example, if in the opinion of the
Sub-Adviser, interest rates generally are expected to decline, the Fund may sell
its shorter term securities and purchase longer term securities in order to
benefit from greater expected relative price appreciation; however, the
securities sold may have a higher current yield than those being purchased. The
success of this strategy will depend on the Sub-Adviser's ability to forecast
changes in interest rates. Moreover, the Fund intends to manage its portfolio
actively by taking advantage of trading opportunities such as sales of portfolio
securities and purchases of higher yielding securities of similar quality due to
distortions in normal yield differentials.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.
<PAGE>   70

- --------------------------------------------------------------------------------

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

       Interest Rate Risk -- In general, when interest rates go up, prices of
       fixed income securities go down. Securities with longer maturities are
       subject to greater fluctuations in value than securities with shorter
       maturities.

       Spread Risk -- The price of a fixed income security is generally
       determined by adding an interest rate spread to a benchmark interest
       rate, such as the U.S. Treasury rate. As the spread on a security widens
       (or increases), the price (or value) of the security falls.

       Default Risk -- An issuer of a security may default on its obligation to
       pay principal and/or interest.

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk -- An issuer of a security may prepay principal
       earlier than scheduled, which could force the Fund to reinvest in lower
       yielding securities.

       Extension Risk -- Slower than expected principal payments on a
       mortgage-backed or asset-backed security may extend such security's life,
       thereby locking in a below-market interest rate, increasing the
       security's duration and reducing the value of the security.

     - Derivative Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security, as well as credit risk with
       respect to the counterparty to the derivative instrument. The use of
       derivatives may reduce returns.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Mortgage Income
Fund has not yet commenced operations, there is no performance information
included in this Prospectus.

 ING NATIONAL TAX-EXEMPT BOND FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income that is exempt from federal income taxes, consistent
with preservation of capital.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and, as a matter of fundamental policy,
invest at least 80% of its total assets in a portfolio of municipal obligations.
Municipal obligations are debt obligations issued by states, territories and
possessions of the United States and the District of Columbia and their
political subdivisions, agencies and instrumentalities, or multi-state agencies
or authorities the interest from which is, in the opinion of bond counsel of the
issuer, exempt from federal income tax. Under normal market conditions, the Fund
will invest at least 80% of its total assets in securities the interest on which
is not a preference item for purposes of the federal alternative minimum tax. Up
to 20% of the Fund's total assets may be invested in taxable debt securities
when sufficient tax-exempt municipal obligations are not available for purchase.
The taxable securities in which the Fund may invest include U.S. Government
securities, instruments of U.S. commercial banks or savings and loan
institutions which have total assets of $1 billion or more as shown on the last
published financial statements at the time of investment, and repurchase
agreements involving any of such securities.

     There are no restrictions on the average maturity of the Fund or, on the
maturity of any single investment. Maturities may vary widely depending on the
Sub-Advisers assessment of interest rate trends and other economic or market
factors. The Fund may purchase the following types of municipal obligations, but
only if such securities, at the time of purchase, either have the requisite
rating, or are of comparable quality if unrated: (i) municipal bonds rated
investment grade (for example, rated at least BBB by Standard & Poor's Rating
Group or Baa by Moody's Investor Services) or have an equivalent rating by a
nationally recognized statistical rating organization, or of comparable quality
if unrated; (ii) municipal notes receiving the highest rating by such a rating
agency; and (iii) tax-exempt commercial paper receiving the highest rating by
such a rating agency.

     The Fund may invest in variable and floating rate obligations, may purchase
securities on a "when-issued" basis, and reserves the right to engage in
transactions involving standby commitments. The Fund may also purchase other
types of tax-exempt instruments as long as they are of a quality equivalent to
the long-term bond or commercial paper ratings stated above. The Fund will not
invest more than 15% of its net assets in illiquid securities. The Fund may
engage in swap agreements.

     Not more than 25% of the Fund's total assets will be invested in either (i)
municipal obligations whose issuers are located in the same state or (ii)
municipal obligations the interest on which is derived from revenues of similar
type projects. The second restriction does not apply to municipal obligations in
any of the following categories: public housing authorities; general obligations
of states and localities; state and local housing finance authorities; or
municipal utilities systems.

     In choosing instruments for the Fund, the Sub-Adviser identifies interest
rate trends and then sets a target duration
<PAGE>   71
ING FUNDS TRUST                                                                9
- --------------------------------------------------------------------------------

and creates the portfolio around such target. The Sub-Adviser analyzes sectors
of the municipal bond market to determine the appropriate weighting of such
sectors. Individual issues that meet duration and sector criteria are selected
on the basis of yield, quality and marketability.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

       Interest Rate Risk -- In general, when interest rates go up, prices of
       fixed income securities go down. Securities with longer maturities are
       subject to greater fluctuations in value than securities with shorter
       maturities.

       Spread Risk -- The price of a fixed income security is generally
       determined by adding an interest rate spread to a benchmark interest
       rate, such as the U.S. Treasury rate. As the spread on a security widens
       (or increases), the price (or value) of the security falls.

       Default Risk -- An issuer of a security may default on its obligation to
       pay principal and/or interest.

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk -- An issuer of a security may prepay principal
       earlier than scheduled, which could force the Fund to reinvest in lower
       yielding securities.

     - Risk of Municipal Obligations.  There could be economic, business or
       political developments which might affect all municipal obligations of a
       similar type. To the extent that a significant portion of the Fund's
       assets are invested in municipal obligations payable from revenue on
       similar projects, the Fund will be subject to the peculiar risks
       presented by such projects to a greater extent than it would be if the
       Fund's assets were not so invested.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING National
Tax-Exempt Bond Fund commenced operations on November 8, 1999, there is no
performance information included in this Prospectus.

 ING STABLE VALUE FUND

     Investment Objective.  The Fund seeks to provide investors with a higher
level of current income than that of a money market fund, while seeking to
preserve capital and maintain a stable net asset value per share.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of fixed income securities of varying short to intermediate-term
maturities which at the time of purchase are rated BBB- or better by an
nationally recognized statistical rating organization or, if not rated, are
determined to be of comparable quality by the Fund's Sub-Adviser at the time of
purchase. The Fund will seek to maintain a minimum average portfolio quality
rating of "A." The dollar-weighted average duration of the Fund will generally
range between two and one-half years and four and one-half years. Duration is a
measure of a debt security's average life that reflects the present value of the
security's cash flow and, accordingly, is a measure of price sensitivity to
interest rate changes. Generally, the longer the duration, the more volatility
an investor should expect. Because earlier payments on a debt security have a
higher present value, the duration of a security (other than a zero-coupon
security) will be less than the security's stated maturity.

     Any remaining assets may be invested in short term investments, including
money market fund shares, bankers' acceptances, commercial paper, time deposits,
certificates of deposit, and other instruments of foreign and domestic banks and
thrift institutions that the Sub-Adviser believes are appropriate in light of
the Fund's objective. Money market instruments must be rated within the two
highest short-term rating categories by a nationally recognized statistical
rating organization or, if not rated, determined to be of comparable quality by
the Fund's Sub-Adviser at the time of purchase.

     The Fund will also enter into wrapper agreements with highly rated
financial institutions, such as banks or insurance companies ("Wrap Providers"),
which are utilized to stabilize the net asset value of the Fund (the "Wrapper
Agreements"). As a result of the Wrapper Agreements, the Fund's net asset value
should be substantially more stable than short to intermediate-term bond funds,
though not fixed at $1.00 per share as is the case with money market funds. The
reason for this is that the Wrapper Agreements require the Wrap Provider to make
payments to the Fund which protect the Fund against declines in the value of its
<PAGE>   72
 10                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

securities, whether such declines arise from interest rate changes, certain
credit events affecting the securities issuers or, if applicable, credit
enhancers of such securities or otherwise. In addition, by investing in a
portfolio of securities with a longer duration, the Fund intends to achieve
returns higher than that of money market funds over a similar period of time.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. There
is no guarantee that the Fund will maintain a stable value. The Fund may be
affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

       Interest Rate Risk -- In general, when interest rates go up, prices of
       fixed income securities go down. Securities with longer maturities are
       subject to greater fluctuations in value than securities with shorter
       maturities.

       Spread Risk -- The price of a fixed income security is generally
       determined by adding an interest rate spread to a benchmark interest
       rate, such as the U.S. Treasury rate. As the spread on a security widens
       (or increases), the price (or value) of the security falls.

       Default Risk -- An issuer of a security may default on its obligation to
       pay principal and/or interest.

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk -- An issuer of a security may prepay principal
       earlier than scheduled, which would force the Fund to reinvest in lower
       yielding securities.

       Extension Risk -- Slower than expected principal payments on a
       mortgage-backed or asset-backed security may extend such security's life,
       thereby locking in a below-market interest rate, increasing the
       security's duration and reducing the value of the security.

     - Wrapper Risk.  The risks of Wrapper Agreements include the possible
       default by a Wrap Provider, the inability to obtain one or more
       replacement Wrapper Agreements, the failure of the Wrapper Agreements to
       cover all securities held by the Fund, the difficulty in valuing Wrapper
       Agreements due to their illiquid nature and the dependence on a limited
       number of available Wrap Providers.

the Funds with the cost of investing in other mutual funds. Each Example assumes
that:

     - you invest $10,000 in the Fund for the time period indicated;

     - your investment has a 5% return each year;

     - the Fund's operating expenses remain the same, except for the expiration
       of the contractual expense limitations on October 31, 2000;

     - you redeem all of your shares at the end of the time period indicated;
       and

     - with regard to the ING Stable Value Fund, the shares redeemed are not
       subject to the redemption fee.

     Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

                              PRICING ALTERNATIVES

     The Funds, except the ING National Tax-Exempt Bond Fund and ING Stable
Value Fund, offer a choice of five share classes, each with its own sales load
and expense structure, allowing you to invest in the way that best suits your
needs. The ING Stable Value Fund offers only Class A and Class B shares. The ING
National Tax-Exempt Bond Fund offers only Class A, Class B and Class C shares.
Class A, Class B and Class C shares are offered in this Prospectus. Class X and
Class I shares are offered under separate prospectuses. The Class X shares has
different sales charges and other expenses, which may affect performance, and
may be purchased only by certain qualified investors (including, but not limited
to, IRAs, Roth IRAs, SEP IRAs, Simple IRAs and 403(b)(7) plans). The Class I
shares are sold without an initial sales charge and also are not subject to any
Rule 12b-1 fees, shareholder servicing fees or account servicing fees. The Class
I shares may be purchased only by (i) retirement plans affiliated with ING
Group, and (ii) ING Group and its affiliates for purposes of corporate cash
management. Each share class represents an ownership interest in the same
investment portfolio. When you choose your class of shares you should consider
the size of your investment and how long you plan to hold your shares.

     For example, if you select Class A shares, you generally pay a sales load
at the time of purchase. If you buy Class A shares, you will also be subject to
a distribution fee of 0.50% and a shareholder servicing fee of 0.25%. You may be
eligible for a sales load reduction or waiver.

     If you select Class B or C shares, you will invest the full amount of your
purchase price, but you will be subject to a distribution fee of 0.75% and a
shareholder servicing fee of 0.25%. Because these fees are paid out of the
Fund's assets on an ongoing basis, over time these fees increase the cost of
your investment and may cost you more than purchasing the Class A shares and
paying an initial sales load. In addition, you may be subject to a deferred
sales load when you sell Class B or Class C shares.

     The Funds' shares are distributed by ING Funds Distributor, Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Funds' shares may be
sold by retail broker-dealers that are under common control with the Funds. As
of the date of this Prospectus, such broker-dealers are Compulife Investor
Services, Inc., IFG Network Securities, Inc., Locust Street Securities, Inc.,
Multi-Financial Securities Corporation, VESTAX Securities Corporation, ING
Barings Furman Selz LLC and ING Barings LLC.

- ------------------------------

*   If you invest $1,000,000 or more in Class A shares, the Distributor normally
    pays the dealer compensation of 0.5% of the purchase price of the shares to
    the dealer from its own resources at the time of the investment. Although
    you will not pay an initial sales load, if you redeem your shares within one
    year after purchase, you may be charged a deferred sales load of 0.5% of the
    lesser of the original cost of the shares being redeemed or your redemption
    investment proceeds. This footnote does not apply to the ING Stable Value
    Fund.

     The deferred sales load relating to Class A shares will be reduced or
waived in the same circumstances as described for Class B shares below.

     No initial sales load is applied to Class A shares of the ING Stable Value
Fund, or to Class A shares of any Fund that you purchase through the
reinvestment of dividends or distributions.

     A reduced or waived sales load on a purchase of Class A shares may apply
for purchases under a "Right of Accumulation" or "Letter of Intent". The Right
of Accumulation permits you to pay the sales load that would apply to the cost
or value (whichever is higher) of all shares you own in the ING Funds at the
time of your current purchase. A Letter of Intent permits you to pay the sales
load that would be applicable if you add up all shares of the ING Funds that you
agree to buy within a 13-month period. Of the Letter of Intent amount, 5% will
be held in escrow to
<PAGE>   79
ING FUNDS TRUST                                                               17
- --------------------------------------------------------------------------------

cover additional sales charges which may be due if your total investments over
the 13 month period are not sufficient to qualify for a sales charge reduction.
Certain restrictions apply. In order for the sales charge reductions to be
effective under either of these programs, the Transfer Agent must be notified of
the reduction request when the purchase order is placed. Additional information
concerning these programs can be obtained from the Funds by calling
1-877-INFO-ING.

     With regard to Funds that charge an initial sales load, the initial sales
load on Class A shares is waived with respect to the following types of
investments:

     - Purchases by the Investment Manager, ING Group or any affiliated company,
       including employee benefit plans established by any such entity.

     - Purchases by officers, directors, trustees and employees of the Funds,
       the Investment Manager and their affiliates, including members of the
       immediate families of such individuals.

     - Purchases by broker-dealers who have a sales agreement with the
       Distributor and their registered personnel and employees, including
       members of the immediate families of such registered personnel and
       employees.

     - Purchases by clients of broker-dealers, investment advisers, third-party
       administrators or consultants that have entered into an agreement with
       the Distributor providing for the use of Fund shares in investment
       products or services made available to their clients.

     - Purchases by employees of firms providing the Funds or their affiliates
       with legal, administrative, marketing or other services, including
       members of the immediate families of such individuals.

     - Purchases paid for with the proceeds of shares redeemed in the prior 180
       days from another mutual fund on which an initial sales load or CDSL was
       paid.

     - Purchases by 401(k) plans and other defined contribution plans with at
       least 25 eligible employees; 403(b)(7) or 457 plans under ERISA; and
       non-qualified deferred compensation plans.

     - Purchases constituting loan repayments by a retirement plan participant.

     - Purchases by former participants in a qualified retirement plan, where a
       portion of the plan was invested in the Funds.

     - Purchases under arrangements between the Distributor and organizations
       which make recommendations to or permit group solicitations of its
       employees, members or participants.

     If you redeem Class A shares and within 90 days buy new shares of the same
class, you will not pay a sales load on the new purchase amount and you will
receive a credit for any CDSL paid. If such reinstated shares are then redeemed
within one year of the initial purchase, the CDSL will be imposed upon the
redemption. The amount eligible for this "Reinstatement Privilege" may not
exceed the amount of your redemption proceeds. To exercise the privilege,
contact the Funds at 1-877-INFO-ING.

 CLASS B SHARES - DEFERRED SALES LOAD ALTERNATIVE

     If you select Class B shares, you do not pay an initial sales load at the
time of purchase. However, if you redeem your Class B shares within 6 years
after purchase, you may be required to pay a deferred sales load (except for the
ING Stable Value Fund). You will also pay distribution fees of 0.75% and
shareholder servicing fees of 0.25% each year. Because these fees are paid out
of a Fund's assets on an ongoing basis, over time these fees increase the cost
of your investment and may cost you more than purchasing the Class A shares and
paying an initial sales load. The Distributor uses the money that it receives
from the deferred sales loads and the distribution fees to cover the costs of
marketing, advertising and compensating the securities dealer who assists you in
purchasing Fund shares. Although Class B shares are sold without an initial
sales load, the Distributor normally pays a sales commission of 4.00% of the
purchase price of Class B shares to the dealer from its own resources at the
time of sale.

     If you redeem Class B shares within 6 years after purchase, you may be
charged a deferred sales load. The amount of the load gradually decreases as you
hold your shares over time, according to the following schedule:

<TABLE>
<CAPTION>
REDEMPTION DURING                          SALES LOAD*

</TABLE>

- ------------------------------

*   The sales load will apply to the lesser of the original cost of the shares
    being redeemed or the proceeds of your redemption. Shares acquired through
    reinvestment of dividends or distributions are not subject to a deferred
    sales load.

     The deferred sales load relating to Class B shares will be waived in
certain circumstances, such as:

     - Mandated minimum post-retirement withdrawals from an IRA or other
       retirement plan if you are over 59 1/2 years old.

     - Redemptions resulting from shareholder death or disability as long as the
       waiver request is made
<PAGE>   80
 18                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

       within one year of death or disability or, if later, reasonably promptly
       following completion of probate.

     - Redemptions through the Systematic Withdrawal Plan of up to 10% per year
       of the initial account balance, which must be at least equal to $20,000.

     - Redemptions resulting from closure by the Fund of the account in which
       shares are held.

     To determine whether the Class B CDSL applies to a redemption, the Fund
redeems shares in the following order: (i) shares acquired by reinvestment of
dividends and capital gains distributions; (ii) shares held for over six years;
and (iii) shares in the order they were purchased (such that shares held the
longest are redeemed first). In the table above, a "year" is a 12 month period.
All purchases are considered to have been made on the business day of the month
in which the purchase was made.

     Your Class B shares convert automatically into Class A shares eight years
after purchase (except for the ING Stable Value Fund). Any Class B shares
received through reinvestment of dividends or distributions paid on converting
shares will also convert at that time. Class A shares are subject to lower
annual expenses than Class B shares. The conversion of Class B shares to Class A
shares is not a taxable event for federal income tax purposes.

     If you redeem Class B shares and within 90 days buy new shares of the same
class, you will receive a credit for any CDSL paid. If such reinstated shares
are then redeemed within six years of the initial purchase, the CDSL will be
imposed upon the redemption. The amount eligible for this "Reinstatement
Privilege" may not exceed the amount of your redemption proceeds. To exercise
the privilege, contact the Funds at 1-877-INFO-ING.

 CLASS C SHARES - LEVEL SALES LOAD ALTERNATIVE

     If you select Class C shares, you do not pay an initial sales load at the
time of purchase. However, if you redeem your Class C shares within one year
after purchase, you may be required to pay a deferred sales load. You will also
pay distribution fees of 0.75% and shareholder servicing fees of 0.25% each
year. Because these fees are paid out of a Fund's assets on an ongoing basis,
over time these fees increase the cost of your investment and may cost you more
than purchasing the Class A shares and paying an initial sales load. The
Distributor uses the money that it receives from the deferred sales loads and
the distribution fees to cover the costs of marketing, advertising and
compensating the securities dealer who assists you in purchasing Fund shares.
Although Class C shares are sold without an initial sales load, the Distributor
normally pays a sales commission of 1.00% of the purchase price of Class C
shares to the dealer from its own resources at the time of sale.

     If you redeem Class C shares within one year after purchase, you may be
charged a deferred sales load of 1.00%. The charge will apply to the lesser of
the original cost of the shares being redeemed or the proceeds of your
redemption. You will not be charged a deferred sales load when you redeem shares
that you acquire through reinvestment of Fund dividends or distributions. The
deferred sales load relating to Class C shares will be reduced or waived in the
same circumstances as described for Class B shares above.

     Class C shares do not offer a conversion privilege.

     If you redeem Class C shares and within 90 days buy new shares of the same
class, you will receive a credit for any CDSL paid. If such reinstated shares
are then redeemed within one year of the initial purchase, the CDSL will be
imposed upon the redemption. The amount eligible for this "Reinstatement
Privilege" may not exceed the amount of your redemption proceeds. To exercise
the privilege, contact the Funds at 1-877-INFO-ING.

                             HOW TO PURCHASE SHARES

     Orders for the purchase of shares of the Funds will be executed at the net
asset value per share plus any applicable sales load ("the public offering
price") next determined after an order has been received. The public offering
price of each Fund is determined as of the close of regular trading on the New
York Stock Exchange (normally 4 p.m. Eastern time) on each day the Exchange is
open for business.

     The minimum initial investment in a Fund is $2,000 ($1,000 for an IRA
investment or any qualified plan). Any subsequent investments must be at least
$50, including an IRA or qualified plan investment. The Distributor may waive
these minimums from time to time. All initial investments should be accompanied
by a completed Account Application. An Account Application accompanies this
Prospectus. A separate application is required for an IRA or qualified plan
investor. All funds received are invested in full and fractional shares of the
appropriate Fund. Certificates for shares are not issued.

     Shares of the Funds, except the ING Stable Value Fund, may be purchased by
investors for retirement and non-retirement accounts. The Class A shares of the

investors for traditional IRAs, Roth IRAs, simplified employee pension IRAs
("SEP-IRAs"), IRAs that are part of a savings incentive match plan for employees
("SIMPLE IRAs"), Keogh plans and educational IRAs.

     When you purchase shares of a Fund, please specify the class of shares that
you wish to purchase. If you do not choose a class of shares, then your
investment will be made in Class A shares. The Funds reserve the right to reject

     IRA investments made through the ING Auto-Asset Accumulation Plan or Direct
Deposit Plans will be treated as current year contributions only. Prior year
contributions through the ING Auto-Asset Accumulation Plan or Direct Deposit
Plans are prohibited. IRA investments cannot exceed Internal Revenue Service
stated maximums for investing in a calendar year. It is the account holder's
responsibility to ensure that their account(s) are within these maximum
investment guidelines.

                              HOW TO REDEEM SHARES

     You may redeem your shares, in whole or in part, on each day a Fund is
valued. Shares will be redeemed without charge (except for any applicable CDSL
and, with respect to the ING Stable Value Fund, any applicable redemption fee as
described below) at the net asset value next determined after a redemption
request in good order has been received by the Funds. In the instance where you
own more than one class of shares and the class of shares being redeemed are not
subject to the CDSL, those shares with the highest Rule 12b-1 fee will be
redeemed in full prior to any redemption of shares with a lower Rule 12b-1 fee.

     The ING Stable Value Fund will deduct a 2.00% redemption fee for Class A
shares, except for (i) redemptions made upon at least 12 months' prior written
notice to the Fund, (ii) the participant's death, retirement, termination or
disability (as disability is defined in applicable provisions of Section 72 of
the Code), (iii) to fund participant loans and other "in service" withdrawals
made pursuant to Plan terms, and (iv) transfers to other Plan investment options
that are not Competing Funds. A Competing Fund, being either affiliated or
unaffiliated with the Funds, is defined as a fixed income investment option with
a targeted average duration of 3 years or less, or any investment option that
seeks to maintain a stable value per share, including money market funds. Unlike
the CDSL, which is paid to the Distributor, the redemption fee is paid back to
the Fund.

     The ING Stable Value Fund will deduct a 2.00% redemption fee for Class B
shares, except for (i) redemptions made upon at least 12 months prior written

- --------------------------------------------------------------------------------

notice to the Fund, and (ii) redemptions made by an IRA owner after such owner
reaches age 59 1/2 years of age, provided that owner has held those shares for
at least 12 consecutive months immediately prior to the redemption.

     When purchases are made by check in any Fund, redemption proceeds will be
made available immediately upon clearance of the purchase check, which may take
up to 15 calendar days. You may avoid this delay by investing through wire
transfers of federal funds.

     Once your shares are redeemed, the Funds will ordinarily send the proceeds
by check to you at the address of record on the next business day. To ensure
acceptance of your redemption request, it is important to follow the procedures
described below. If you purchased your shares through an Authorized Broker or
Investment Adviser, please contact them to inquire which redemption methods are
available to you. Under certain circumstances described below, a signature
guarantee may be required. You may redeem your shares using any of the following
methods:

  Optional Insurance Benefit      Insurance companies, including certain companies

                                  insurance coverage available to persons on whose behalf
                                  shares of the Funds are purchased. The benefits of this

     The Funds reserve the right to redeem in kind. That is, the Funds may honor
redemption requests with readily marketable portfolio securities instead of cash
if during any 90-day period redemptions exceed the lesser of $250,000 or 1% of
the net assets of the redeeming Fund at the beginning of such period. You may
incur transaction costs associated with converting these securities to cash.

     Due to the high costs of maintaining small accounts, the Funds may ask that
you increase your account balance if (1) the value of your account falls below
$500 for three consecutive months as a result of redemptions or exchanges, and
(2) your account has been in existence for at least one year and you have not
made any additional purchases in the account within the preceding six calendar
months. If the account balance remains below the minimum requirement for 60 days
after you are notified, the Funds may close your account and send you the
redemption proceeds.

redeem, transfer, or exchange shares of the Funds. Signature guarantees are
required for:

     - redemptions by mail in excess of $50,000;

     - redemptions by mail if the proceeds are to be paid to someone other than
       the name(s) in which the account is registered;

     - redemptions requesting proceeds to be sent by wire to other than the bank
       of record for the account;

     - redemptions requesting proceeds to be sent to a new address or an address
       that has been changed within the past 15 days;

     - requests to transfer the registration of shares to another owner;

     - telephone exchange and telephone redemption authorization forms;

     - changes in previously designated wiring instructions; or

     - redemptions or exchanges of shares previously reported as lost/abandoned
       property, whether or not the redemption amount is under $50,000 or the
       proceeds are to be sent to the address of record.

     The foregoing requirements may be waived or modified upon notice to
shareholders.

     Acceptable guarantors include banks, broker-dealers, credit unions,
national securities exchanges, savings associations and any other organization,
provided that such institution or organization qualifies as an "eligible
guarantor institution" as that term is defined in rules adopted by the
Securities and Exchange Commission. For information regarding whether a
particular institution or organization qualifies as an "eligible guarantor
institution," contact the Funds at 1-877-INFO-ING.

                               EXCHANGE PRIVILEGE

     Except as described below, Class A shares of any Fund may be exchanged for
Class A shares of any other Fund. Any sales load previously paid on the shares
being exchanged will be credited toward the sales load payable on the shares
being acquired.

     Except as described below, Class B shares and Class C shares of a Fund, as
well as Class A shares subject to a contingent deferred sales load, may be
exchanged, based on the per share net asset values, for the same class of shares
of any other Fund. You will receive credit for the period of time you held the
shares being exchanged when determining whether the acquired shares, when
redeemed, will be subject to a contingent deferred sales load.

     Shares of the ING Stable Value Fund may not be exchanged for shares of any
Fund that would be classified as a Competing Fund. Exchanges may be made to a
non-Competing Fund and, after at least a three-month period in such
non-Competing Fund, an exchange to a Competing Fund may be made without
restriction.

     Your exchange will be processed at the next determined net asset value (or
offering price, if there is a sales load) after the Funds receive your request.
A new account opened by exchange must be established with the same name(s),
address and social security number as the existing account.

     You may only exchange shares into a Fund which is authorized for sale in
your state of residence. The Funds may limit each account to eight exchanges per
calendar year. The Funds may change or discontinue the exchange privilege after
giving you 60 days' prior notice. An exchange of shares is a taxable event on
which you may realize a gain or loss. You may exchange shares using any of the
following methods:

                               PRICING OF SHARES

     Each of the Funds prices its shares based on its net asset value. The Funds
value portfolio securities for which market quotations are readily available at
market price. These Funds value 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 Funds may value the security at its fair value as determined
in good faith by or under the supervision of the Board of Trustees. The effect
of using fair value pricing is that a Fund's net asset value will be subject to
the judgment of the Board of Trustees or its designee instead of being
determined by the market. Because some of the Funds may invest in securities
that are primarily listed on foreign exchanges, the value of those Funds' shares
may change on days when you will not be able to purchase or redeem shares.

     Pursuant to procedures adopted by the Board of Trustees, the fair value of
a Wrapper Agreement ("Wrapper Value") entered into by the ING Stable Value Fund
generally will be equal to the difference between the "Book Value" and the
market value (plus accrued interest on the underlying securities) of the portion
of the Fund's assets
<PAGE>   87
ING FUNDS TRUST                                                               25
- --------------------------------------------------------------------------------

covered by the Agreement ("Covered Assets"). Generally, the Book Value of the
Covered Assets is their purchase price plus interest on the Covered Assets
accreted at a rate specified in the Wrapper Agreement ("Crediting Rate"). The
Crediting Rate used in computing Book Value is calculated by a formula specified
in the Wrapper Agreement and is adjusted periodically. If the market value (plus
accrued interest on the underlying securities) of the Covered Assets is greater
than their Book Value, the Wrapper Value will be reflected as a liability of the
Fund in the amount of the difference, i.e., a negative value, reflecting the
potential liability of the Fund to the Wrapper Provider. If the market value
(plus accrued interest on the underlying securities) of the Covered Assets is
less than their Book Value, the Wrapper Value will be reflected as an asset of
the Fund in the amount of the difference, i.e., a positive value, reflecting the
potential liability of the Wrapper Provider to the Fund. In performing its fair
value determination, the Board expects to consider the creditworthiness and
ability of a Wrapper Provider to pay amounts due under the Wrapper Agreement. If
the Board determines that a Wrapper Provider is unable to make such payments,
that Board may assign a fair value to the Wrapper Agreement that is less than
the difference between the Book Value and the market value (plus accrued
interest on the underlying securities) of the applicable Covered Assets and the
Fund might be unable to maintain net asset value stability.

     Each Fund determines the net asset value of its shares as of the close of
the NYSE (normally 4:00 p.m., Eastern time) on each day the NYSE is open for
business. The price at which a purchase or redemption is effected is based on
the next calculation of a Fund's net asset value after the order is placed.

                          DIVIDENDS AND DISTRIBUTIONS

     Each Fund intends to distribute to its shareholders substantially all of
its investment company taxable income (which includes dividends and interest and
the excess, if any, of net short-term capital gains over net long-term capital
losses). Each of the Funds will declare dividends daily and pay dividends
monthly. In addition, each Fund intends to distribute, at least annually,
substantially all of its net capital gains (the excess of net long-term capital
gains over net short-term capital losses). In determining amounts of capital
gains to be distributed, any capital loss carryovers from prior years will be
applied against capital gains.

     Dividends and distributions will be reinvested in additional shares of a
Fund at net asset value unless you elect to receive such dividends and
distributions in cash. If you redeem all or a portion of Fund shares prior to a
dividend payment date, you will be entitled on the next dividend payment date to
all dividends declared but unpaid on those shares at the time of their
redemption.

     If you elect to receive distributions in cash and the post office cannot
deliver your checks or if you do not cash your checks within six months, your
dividends may be reinvested in your account at the then-current net asset value
and your account will be converted to the reinvestment option. You will not
receive interest on the amount of your uncashed checks.

     You may also elect to automatically invest dividends and distributions paid
by a Fund in shares of any other ING Fund of which you are a shareholder. Shares
of the other Fund will be purchased at that Fund's then-current net asset value.

     You may also elect to transfer electronically dividends and distributions
paid by a Fund to your designated bank account if your financial institution is
an Automated Clearing House member. Banks may charge a fee for the service.

     The elections described above may be made either on the Account Application
or by calling the Fund at 1-877-INFO-ING.

     ING Stable Value Fund.  The Fund may declare and pay dividends in amounts
which are not equal to the amount of the net investment income it actually
earned. Consequently, in any year the amount actually distributed may differ
from the income earned. If, for any year, those distributions exceed the income
earned, the excess may be considered a return of capital. On the other hand, if
the income earned exceeds the amount of the dividends distributed, the Fund may
make an additional distribution of that excess (an "Additional Distribution").
To enable the Fund to maintain a stable NAV per share in the event of an
Additional Distribution, the Trust Board may declare, effective on the
ex-distribution date of an Additional Distribution, a reverse split of the
shares in an amount that will cause the total number of shares held by each
shareholder, including shares acquired on reinvestment of that distribution, to
remain the same as before that distribution was paid.

     For example, if the Fund declares an Additional Distribution of $0.10 per
share at a time when the net asset value per share is $10.00, a shareholder
holding one share would receive 0.01 additional shares on reinvestment of that
distribution. If there were no reverse split, the per share NAV of the 1.01
shares held by the shareholder would be approximately $9.90, and the aggregate
value thereof would be $10.00. If a 1.01-for-1 reverse share split were
declared, however, the shareholder's holdings would be consolidated back into
one share having an NAV of $10.00. Thus, a reverse share split will not affect
the value of the total holdings of a shareholder.

- --------------------------------------------------------------------------------

                                     TAXES

     All Funds.  Each Fund is treated as a separate entity for federal income
tax purposes. Each Fund intends to qualify as a regulated investment company by
satisfying the requirements under Subchapter M of the Internal Revenue Code of
1986 (the "Code"), including requirements with respect to diversification of
assets, distribution of income and sources of income. By so qualifying, each
Fund generally will not be subject to federal income tax to the extent that it
distributes investment company taxable income and net realized capital gains in
the manner required under the Code.

     Distributions by a Fund of its taxable net investment income and the
excess, if any, of its net short-term capital gain over its net long-term
capital loss are taxable to shareholders as ordinary income. Distributions by a
Fund of the excess, if any, of its net long-term capital gain over its net
short-term capital loss are designated as capital gain dividends and are taxable
as long-term capital gains, regardless of the length of time you have held your
shares.

     Distributions will be treated in the same manner for federal income tax
purposes whether you receive them in cash or reinvest them in additional shares
of the Fund. In general, distributions by a Fund are taxable to you in the year
in which the distributions are made. However, certain distributions made during
January will be treated as having been paid by a Fund and received by you on
December 31 of the preceding year.

     Investment income received by a Fund from sources within foreign countries
may be subject to foreign income taxes withheld at the source. To the extent any
Fund is liable for foreign income taxes withheld at the source, each Fund
intends, if possible, to operate so as to meet the requirements of the Code to
"pass through" to the Fund's shareholders credits for foreign income taxes paid,
but there can be no assurance that any Fund will be able to do so.

     A redemption or an exchange of shares is a taxable transaction on which you
may realize a gain or loss. Any gain or loss realized upon the sale or other
disposition of shares of a Fund generally will be a capital gain or loss which
will be long-term or short-term depending on how long you have held the shares.
Any loss realized upon a sale or disposition of shares within six months from
the date of their purchase will be treated as a long-term capital loss to the
extent of any capital gain distributions received on such shares.

     Under the backup withholding rules of the Code, you may be subject to 31%
withholding of federal income tax on ordinary income dividends paid by a Fund.
In order to avoid this backup withholding, you must provide the Funds with a
correct taxpayer identification number or certify that you are otherwise exempt
from or not subject to backup withholding.

     You will be notified annually as to the federal tax status of distributions
made by the Funds in which you invest. Depending on your residence for tax
purposes, distributions also may be subject to state and local taxes. You should
consult your own tax advisor as to the federal, state and local tax consequences
of investing in shares of the Funds in your particular circumstances.

     ING National Tax-Exempt Bond Fund.  If the ING National Tax-Exempt Bond
Fund complies with applicable requirements of the Code, then dividends derived
from interest on qualified state and local bonds ("tax-exempt bonds") will
constitute exempt-interest dividends and will not be subject to federal income
tax. Some portion of the exempt-interest dividends paid by the Fund could be
treated as an item of "tax preference" for purposes of the alternative minimum
tax. Under the Code, interest on certain types of tax-exempt bonds is designated
as an item of tax preference for purposes of the alternative minimum tax on
individuals and corporations. Therefore, if the Fund were to invest in such
types of bonds, you would be required to treat as an item of tax preference that
part of the distributions by the Fund that is derived from interest income on
such bonds.

     Entities or persons who are "substantial users" (or persons related
thereto), as defined in the Code, of facilities financed by tax-exempt bonds
issued for certain private activities should consult their tax advisor before
purchasing shares of the Fund.

     You are required to report the amount of tax-exempt interest received each
year, including exempt-interest dividends paid by the Fund, on your federal
income tax return. Exempt-interest dividends and other distributions paid by the
Fund are included in the tax base for determining the taxability of social
security or railroad retirement benefits. Interest on debt incurred to purchase
or carry shares of the Fund may not be deductible for federal income tax
purposes.

                  MORE INFORMATION ABOUT STRATEGIES AND RISKS

     A Fund's risk profile is largely a factor of the principal securities in
which it invests and investment techniques that it uses. The following pages
discuss the risks associated with certain of the types of securities in which
the Funds may invest and certain of the investment practices that the Funds may
use. For more information about these and other types of securities and
investment techniques used by the Funds, see the Statement of Additional
Information. Unless indicated otherwise, the following descriptions apply to all
Funds.

     Many of the investment techniques and strategies discussed in this
Prospectus and in the Statement of
<PAGE>   89
ING FUNDS TRUST                                                               27
- --------------------------------------------------------------------------------

Additional Information are discretionary, which means that the Investment
Manager or Sub-Adviser can decide whether to use them or not. The Investment
Manager or Sub-Adviser may also use investment techniques or make investments in
securities that are not a part of the Fund's principal investment strategy.

     Temporary Defensive Strategies (All Funds).  When the Investment Manager or
Sub-Adviser to a Fund anticipates unusual market or other conditions, the Fund
may temporarily depart from its principal investment strategies. Under such
circumstances, up to 100% of the Fund's assets may be invested in investment
grade fixed income securities (for example, rated at least BBB by Standard &
Poor's Rating Group or Baa by Moody's Investor Services), money market
securities, certificates of deposit, bankers' acceptances, commercial paper or
in any other securities which in either the Investment Manager's or
Sub-Adviser's opinion are more conservative than the types of securities in
which the Fund typically invests. To the extent a Fund is engaged in temporary
defensive investments, it will not be pursuing its investment objective.

     Investments in Foreign Securities (All Funds except ING Mortgage Income
Fund and ING National Tax-Exempt Bond Fund).  There are certain risks in owning
foreign securities, including those resulting from: fluctuations in currency
exchange rates; devaluation of currencies; political or economic developments
and the possible imposition of currency exchange blockages or other foreign
governmental laws or restrictions; reduced availability of public information
concerning issuers; accounting, auditing and financial reporting standards or
other regulatory practices and requirements that are not uniform when compared
to those applicable to domestic companies; settlement and clearance procedures
in some countries that may not be reliable and can result in delays in
settlement; higher transaction and custody expenses than for domestic
securities; and limitations on foreign ownership of equity securities. Also,
securities of many foreign companies may be less liquid and the prices more
volatile than those of domestic companies. With certain foreign countries, there
is the possibility of expropriation, nationalization, confiscatory taxation and
limitations on the use or removal of funds or other assets of the Funds,
including the withholding of dividends.

     Each Fund that invests in foreign securities may enter into foreign
currency transactions either on a spot or cash basis at prevailing rates or
through forward foreign currency exchange contracts in order to have the
necessary currencies to settle transactions or to help protect the Fund against
adverse changes in foreign currency exchange rates. Such efforts could limit
potential gains that might result from a relative increase in the value of such
currencies, and might, in certain cases, result in losses to the Fund.

     Emerging Market Investments (ING High Yield Bond Fund, ING Intermediate
Bond Fund and ING International Bond Fund).  Because of less developed markets
and economies and, in some countries, less mature governments and governmental
institutions, the risks of investing in foreign securities can be intensified in
the case of investments in issuers domiciled or doing substantial business in
emerging market countries. These risks include: high concentration of market
capitalization and trading volume in a small number of issuers representing a
limited number of industries, as well as a high concentration of investors and
financial intermediaries; political and social uncertainties; over-dependence on
exports, especially with respect to primary commodities, making these economies
vulnerable to changes in commodity prices; overburdened infrastructure and
obsolete financial systems; environmental problems; less well developed legal
systems; and less reliable custodial services and settlement practices.

     High Yield Securities (ING High Yield Bond Fund, ING Intermediate Bond Fund
and ING International Bond Fund). Investments in high yield securities generally
provide greater income and increased opportunity for capital appreciation than
investments in higher quality debt securities, but they also typically entail
greater potential price volatility and principal and income risk. High yield
securities are not considered investment grade, and are regarded as
predominantly speculative with respect to the issuing company's continuing
ability to meet principal and interest payments. The prices of high yield
securities have been found to be less sensitive to interest rate changes than
higher-rated investments, but more sensitive to adverse economic downturns or
individual corporate developments. High yield securities structured as
zero-coupon or payment-in-kind securities tend to be more volatile. The
secondary market in which high yield securities are traded is generally less
liquid than the market for higher-grade bonds. At times of less liquidity, it
may be more difficult to value high yield securities.

     Corporate and Municipal Debt Securities (All Funds). Corporate debt
securities are subject to the risk of the issuer's inability to meet principal
and interest payments on the obligation and may also be subject to price
volatility due to such factors as interest rate sensitivity, market perception
of the credit-worthiness of the issuer and general market liquidity. When
interest rates decline, the value of the debt securities can be expected to
rise, and when interest rates rise, the value of those securities can be
expected to decline. Debt securities with longer maturities tend to be more
sensitive to interest rate movements than those with shorter maturities.

     Initial Public Offerings (All Funds).  A significant portion of a Fund's
return may be attributable to its investment in initial public offerings. When a
Fund's asset base is small, the impact of such investments on a Fund's return
will be magnified. As the Fund's assets grow, it is
<PAGE>   90
 28                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

probable that the effect of the Fund's investment in initial public offerings on
the Fund's total return will decline.

     U.S. Government Securities (All Funds).  Some U.S. Government agency
securities may be subject to varying degrees of credit risk, and all U.S.
Government securities may be subject to price declines in the securities due to
changing interest rates.

     Convertible Securities (All Funds except ING National Tax-Exempt Bond
Fund).  The price of a convertible security will normally fluctuate in some
proportion to changes in the price of the underlying equity security, and as
such is subject to risks relating to the activities of the issuer and general
market and economic conditions. The income component of convertible securities
causes fluctuations based upon changes in interest rates and the credit quality
of the issuer. Convertible securities are often lower rated securities. A Fund
may be required to redeem or convert a convertible security before the holder
would otherwise choose.

     Other Investment Companies (All Funds).  Each Fund may invest up to 10% of
its assets in other unaffiliated investment companies. There is no limit with
regard to investments in affiliated investment companies. When a Fund invests in
other investment companies, you indirectly pay a proportionate share of the
expenses of that other investment company (including management fees,
administration fees, and custodial fees) in addition to the expenses of the
Fund.

     Restricted and Illiquid Securities (All Funds).  Each Fund may invest up to
15% of its net assets in restricted and illiquid securities. If a security is
illiquid, the Fund might be unable to sell the security at a time when the
sub-adviser might wish to sell, and the security could have the effect of
decreasing the overall level of the Fund's liquidity. Further, the lack of an
established secondary market may make it more difficult to value illiquid
securities, which could vary from the amount the Fund could realize upon
disposition. Restricted securities, i.e., securities subject to legal or
contractual restrictions on resale, may be illiquid. However, some restricted
securities may be treated as liquid, although they may be less liquid than
registered securities traded on established secondary markets.

     Mortgage-Related Securities (All Funds except ING National Tax-Exempt Bond
Fund).  Although mortgage loans underlying a mortgage-backed security may have
maturities of up to 30 years, the actual average life of a mortgage-backed
security typically will be substantially less because the mortgages will be
subject to normal principal amortization, and may be prepaid prior to maturity.
Like other fixed income securities, when interest rates rise, the value of a
mortgage-backed security generally will decline; however, when interest rates
are declining, the value of mortgage-backed securities with prepayment features
may not increase as much as other fixed income securities. The rate of
prepayments on underlying mortgages will affect the price and volatility of a
mortgage-related security, and may have the effect of shortening or extending
the effective maturity of the security beyond what was anticipated at the time
of the purchase. Unanticipated rates of prepayment on underlying mortgages can
be expected to increase the volatility of such securities. In addition, the
value of these securities may fluctuate in response to the market's perception
of the creditworthiness of the issuers of mortgage-related securities owned by a
Fund. Additionally, although mortgages and mortgage-related securities are
generally supported by some form of government or private guarantee and/or
insurance, there is no assurance that private guarantors or insurers will be
able to meet their obligations.

     Asset-Backed Securities (All Funds except ING National Tax-Exempt Bond
Fund).  Asset-backed securities involve certain risks that are not posed by
mortgage-related securities, resulting mainly from the fact that asset-backed
securities often do not contain the benefit of a complete security interest in
the related collateral. The risks associated with asset-backed securities may be
reduced by the addition of credit enhancements such as a bank letter of credit
or a third-party guarantee.

     Derivatives (All Funds).  Generally, derivatives can be characterized as
financial instruments whose performance is derived, at least in part, from the
performance of an underlying asset or assets. Some derivatives are sophisticated
instruments that typically involve a small investment of cash relative to the
magnitude of risks assumed. These may include swap agreements, options, forwards
and futures. Derivative securities are subject to market risk, which could be
significant for those that have a leveraging effect. Many of the Funds do not
invest in these types of derivatives, so please check the description of the
Fund's policies found in the Statement of Additional Information. Derivatives
are also subject to credit risks related to the counterparty's ability to
perform, and any deterioration in the counterparty's creditworthiness could
adversely affect the instrument. A risk of using derivatives is that the adviser
might imperfectly judge the market's direction. For instance, if a derivative is
used as a hedge to offset investment risk in another security, the hedge might
not correlate to the market's movements and may have unexpected or undesired
results, such as a loss or a reduction in gains.

     Dollar Roll Transactions (All Funds except ING National Tax-Exempt Bond
Fund).  The Funds may enter into dollar roll transactions wherein the Fund sells
fixed income securities, typically mortgage-backed securities, and makes a
commitment to purchase similar, but not identical, securities at a later date
from the same party. Like a forward commitment, during the roll period no
payment is made for the securities purchased and no interest or principal
payments on the security accrue to the purchaser, but a Fund assumes the risk of
ownership. A Fund is compensated for entering into dollar roll transactions by
the difference
<PAGE>   91
ING FUNDS TRUST                                                               29
- --------------------------------------------------------------------------------

between the current sales price and the forward price for the future purchase,
as well as by the interest earned on the cash proceeds of the initial sale. Like
other when-issued securities or firm commitment agreements, dollar roll
transactions involve the risk that the market value of the securities sold by
the Funds may decline below the price at which a Fund is committed to purchase
similar securities. In the event the buyer of securities under a dollar roll
transaction becomes insolvent, the Funds' use of the proceeds of the transaction
may be restricted pending a determination by the other party, or its trustee or
receiver, whether to enforce the Funds' obligation to repurchase the securities.

     Repurchase Agreements (All Funds).  Each Fund may enter into repurchase
agreements, which involve the purchase by a Fund of a security that the seller
has agreed to buy back. If the seller defaults and the collateral value
declines, the Fund might incur a loss. If the seller declares bankruptcy, the
Fund may not be able to sell the collateral at the desired time.

     Lending Portfolio Securities (All Funds).  In order to generate additional
income, each Fund may lend portfolio securities in an amount up to 33 1/3% of
its total assets to broker-dealers, major banks, or other recognized domestic
institutional borrowers of securities. As with other extensions of credit, there
are risks of delay in recovery or even loss of rights in the collateral should
the borrower default or fail financially.

     Borrowing (All Funds).  Each Fund may borrow for certain types of temporary
or emergency purposes subject to certain limits. Borrowing may exaggerate the
effect of any increase or decrease in the value of portfolio securities or the
net asset value of a Fund, and money borrowed will be subject to interest costs.
Interest costs on borrowings may fluctuate with changing market rates of
interest and may partially offset or exceed the return earned on borrowed funds.
Under adverse market conditions, a Fund might have to sell portfolio securities
to meet interest or principal payments at a time when fundamental investment
considerations would not favor such sales.

     Reverse Repurchase Agreements (All Funds).  A reverse repurchase agreement
involves the sale of a security, with an agreement to repurchase the same
securities at an agreed upon price and date. Whether such a transaction produces
a gain for a Fund depends upon the costs of the agreements and the income and
gains of the securities purchased with the proceeds received from the sale of
the security. If the income and gains on the securities purchased fail to exceed
the costs, net asset value will decline faster than otherwise would be the case.
Reverse repurchase agreements, as leveraging techniques, may increase a Fund's
yield; however, such transactions may result in a shareholder's loss of
principal.

     Short Sales (ING Intermediate Bond Fund and ING High Yield Bond Fund).  A
"short sale" is the sale by a Fund of a security which has been borrowed from a
third party on the expectation that the market price will drop. If the price of
the security rises, the Fund may have to cover its short position at a higher
price than the short sale price, resulting in a loss.

     Investments in Small- and Mid-Capitalization Companies (ING High Yield Bond
Fund and ING Intermediate Bond Fund).  Certain Funds may invest in small and mid
capitalization companies. Investments in mid-and small-capitalization companies
involve greater risk than is customarily associated with larger, more
established companies due to the greater business risks of small size, limited
markets and financial resources, narrow product lines and the frequent lack of
depth of management. The securities of smaller companies are often traded
over-the-counter and may not be traded in volumes typical on a national
securities exchange. Consequently, the securities of smaller companies may have
limited market stability and may be subject to more abrupt or erratic market
movements than securities of larger, more established growth companies or the
market averages in general.

     Non-diversified Investment Companies (ING International Bond
Fund).  Certain Funds are classified as non-diversified investment companies
under the 1940 Act, which means that each Fund is not limited by the 1940 Act in
the proportion of its assets that it may invest in the obligations of a single
issuer. The investment of a large percentage of a Fund's assets in the
securities of a small number of issuers may cause that Fund's share price to
fluctuate more than that of a diversified investment company.

     Fundamental and Non-Fundamental Policies (All Funds).  Unless otherwise
stated, all investment objectives and policies are non-fundamental and may be
amended without shareholder approval.

     Percentage Investment Limitations (All Funds).  Unless otherwise stated,
percentage limitations in this prospectus apply at the time of investment.

     Portfolio Turnover (All Funds).  Each Fund may engage in frequent and
active trading of portfolio securities to achieve its investment objective. A
high portfolio turnover rate involves greater expenses to a Fund, including
brokerage commissions and other transaction costs, and is likely to generate
more taxable short-term gains for shareholders, which may have an adverse effect
on the performance of the Fund.

                              FINANCIAL HIGHLIGHTS

     The financial highlights table is intended to help you understand the
Funds' financial performance for the fiscal period ended October 31, 1999.
Certain information reflects financial results for a single Fund share. The
total returns in the table represent the rate than an investor would have earned
or lost on an investment in the Funds (assuming reinvestment of all dividends
and distributions). Past performance does not guarantee future results. This
information has been audited by Ernst & Young LLP, independent auditors, whose
report, along with the Funds' financial statements, is included in the Statement
of Additional Information, which is available upon request. Because the
following Funds had not commenced operations prior to October 31, 1999,
financial highlights are not presented for ING Mortgage Income Fund, ING
National Tax-Exempt Bond Fund and ING Stable Value Fund.

                               MONEY MARKET FUNDS

 ING MONEY MARKET FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income as is consistent with the preservation of capital and
liquidity and the maintenance of a stable $1.00 net asset value per share.

     Principal Investment Strategies.  The Fund will operate as a diversified
fund and invest in a portfolio of high-quality, U.S. dollar denominated
short-term debt obligations which are determined by the Sub-Adviser to present
minimal credit risks.

     Portfolio investments of the Fund are valued based on the amortized cost
valuation method pursuant to Rule 2a-7 under the Investment Company Act of 1940.
Obligations in which the Fund invests generally have remaining maturities of 397
days or less, although upon satisfying certain conditions of Rule 2a-7, the Fund
may, to the extent otherwise permissible, invest in instruments subject to
repurchase agreements and certain variable and floating rate obligations that
bear longer final maturities. The dollar-weighted average portfolio maturity of
the Fund will not exceed 90 days.

     The Fund will invest in obligations permitted to be purchased under Rule
2a-7 including, but not limited to, (i) U.S. Government securities and
obligations of its agencies or instrumentalities; (ii) commercial paper,
mortgage-backed and asset-backed securities, guaranteed investment contracts,
loan participation interests, medium-term notes, and other promissory notes,
including floating and variable rate obligations; and (iii) the following
domestic, Yankeedollar and Eurodollar obligations: certificates of deposit, time
deposits, bankers acceptances, commercial paper, and other promissory notes,
including floating and variable rate obligations issued by U.S. or foreign bank
holding companies and their bank subsidiaries, branches and agencies. The Fund
may invest more than 25% of its total assets in instruments issued by domestic
banks.

     The Fund may purchase securities on a "when-issued" basis and purchase or
sell them on a "forward commitment" basis. The Fund may also invest in variable
rate master demand obligations, which are unsecured demand notes that permit the
underlying indebtedness to vary, and provide for periodic adjustments in the
interest rate. The Fund may enter into repurchase agreements.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, four step investment process designed to ensure preservation of
capital and liquidity, as well as adherence to regulatory requirements. The four
steps are:

     - First, a formal list of high-quality issuers is actively maintained;

     - Second, securities of issuers on the approved list which meet maturity
       guidelines and are rated "first tier" (that is, they are given the
       highest short-term rating by at least two nationally recognized
       statistical rating organizations, or by a single rating organization if a
       security is rated only by that organization, or are determined to be of
       comparable quality by the Sub-Adviser pursuant to guidelines approved by
       the Fund's Board of Trustees) are selected for investment;

     - Third, diversification is continuously monitored to ensure that
       regulatory limits are not exceeded; and

     - Finally, portfolio maturity decisions are made based upon expected cash
       flows, income opportunities available in the market and expectations of
       future interest rates.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  An investment in the Fund is not a bank deposit and is
not insured or guaranteed by the Federal Deposit Insurance Corporation or any
other government agency. Although the Fund seeks to preserve the value of your
investment at $1.00 per share, it is possible to lose money by investing in the
Fund. The Fund's yield will vary and the Fund may not achieve as high a level of
current income as other funds that do not limit their investments to the
high-quality securities in which the Fund invests.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an

 ING U.S. TREASURY MONEY MARKET FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income as is consistent with liquidity, maximum safety of
principal and the maintenance of a stable $1.00 net asset value per share.

     Principal Investment Strategies.  The Fund will operate as a diversified
fund and invest in direct short-term obligations of the United States Treasury,
which are backed by the full faith and credit of the United States Government.
The Fund may also invest in repurchase agreements which are fully collateralized
by U.S. Treasury securities. The Fund may purchase U.S. Treasury securities on a
"when-issued" basis and purchase or sell them on a "forward commitment" basis.

     Portfolio investments of the Fund are valued based on the amortized cost
valuation method pursuant to Rule 2a-7 under the Investment Company Act of 1940.
Obligations in which the Fund invests generally have remaining maturities of 397
days or less, although upon satisfying certain conditions of Rule 2a-7, the Fund
may, to the extent otherwise permissible, invest in instruments subject to
repurchase agreements and certain variable and floating rate obligations that
bear longer final maturities. The dollar-weighted average portfolio maturity of
the Fund will not exceed 90 days.

     Maturity decisions are made by the Sub-Adviser based upon liquidity
requirements, yield curve analysis and market expectations of future interest
rates.

 ING NATIONAL TAX-EXEMPT MONEY MARKET FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income that is exempt from federal income tax as is consistent
with the preservation of capital and liquidity and the maintenance of a stable
$1.00 net asset value per share.

     Principal Investment Strategies.  The Fund will operate as a diversified
fund and invest at least 80% of its net assets in a portfolio of high-quality,
short-term municipal obligations, which are determined by the Sub-Adviser to
present minimal credit risks. Municipal obligations are debt obligations issued
by states, territories and possessions of the United States and the District of
Columbia and their political subdivisions, agencies and instrumentalities, or
multi-state agencies or authorities the interest from which is, in the opinion
of bond counsel of the issuer, exempt from federal income tax. The Fund will not
purchase private activity bonds, the interest from which would be a preference
item subject to the federal alternative minimum tax. Although the Sub-Adviser
has no intention of doing so, the Fund may temporarily invest from time to time
up to 20% of its net assets in money market instruments that are subject to
federal income tax. For temporary defensive purposes, the Fund may invest up to
100% of its net assets in money market instruments that are subject to federal
income tax.

     The Fund may purchase securities on a "when-issued" basis and purchase or
sell them on a "forward commitment" basis. The Fund may also invest in
obligations that have floating and variable rates of interest. The Fund may
enter into repurchase agreements.

     Portfolio investments of the Fund are valued based on the amortized cost
valuation method pursuant to Rule 2a-7 under the Investment Company Act of 1940.
Obligations in which the Fund invests generally have remaining maturities of 397
days or less, although upon satisfying certain conditions of Rule 2a-7, the Fund
may, to the extent otherwise permissible, invest in instruments subject to
repurchase agreements and certain variable and floating rate obligations that
bear longer final maturities. The dollar-weighted average portfolio maturity of
the Fund will not exceed 90 days.

     In selecting debt securities for the Fund, the Sub-Adviser seeks to select
those instruments that appear to have the potential to achieve the Fund's
investment objective within the credit and risk tolerances established for the
Fund. In accordance with those policies, the Fund will invest only in
instruments that at the time of investment are rated "first tier" (that is, they
are given the highest short-term rating by at least two nationally recognized
statistical rating organizations, or by a single rating organization if a
security is rated only by that organization, or are determined to be of
comparable quality by the Sub-Adviser pursuant to guidelines approved by the
Fund's Board of Trustees). The Sub-Adviser continually monitors diversification
of the Fund's assets to ensure that regulatory limits are not exceeded.

     In managing the Fund, the Sub-Adviser employs a number of professional
money management techniques, including varying the composition of investments
and the average maturity of the portfolio based upon the Sub-Adviser's
assessment of the relative values of the various money market securities and
future interest rate patterns. These assessments will change in response to
changing economic and money market conditions and to shifts in fiscal and
monetary policy. The Sub-Adviser also seeks to improve yield by taking advantage
of yield disparities that regularly occur in the money markets. For example,
market conditions frequently result in similar securities trading at different
prices. Also, there are frequently differences in the yield between the various
types of money market securities. The Fund seeks to enhance yield by purchasing
and selling securities based upon these yield disparities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  An investment in the Fund is not a bank deposit and is
not insured or guaranteed by the Federal Deposit Insurance Corporation or any

(1) Other expenses are based on estimated amounts for the current fiscal year.

(2) The Investment Manager has entered into expense limitation contracts with
    each of the Funds, under which it will limit expenses of each Fund,
    excluding interest, taxes, brokerage and extraordinary expenses through
    October 31, 2000. The expense limit for each such Fund is shown as "Net
    Expenses". Fee waiver and/or reimbursements by the Investment Manager may

EXAMPLES

     These Examples are intended to help you compare the cost of investing in
the Funds with the cost of investing in other mutual funds. Each Example assumes
that:

     - you invest $10,000 in the Fund for the time period indicated;

     - your investment has a 5% return each year;

     - the Fund's operating expenses remain the same, except for the expiration
       of the contractual expense limitations on October 31, 2000; and

     - you redeem all of your shares at the end of the time period indicated.

     Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

                              PRICING ALTERNATIVES

     The Funds, except ING National Tax-Exempt Money Market Fund, offer a choice
of five share classes, each with its own sales load and expense structure,
allowing you to invest in the way that best suits your needs. The ING National
Tax-Exempt Money Market Fund offers only Class A, Class B and Class C shares.
Class A, Class B and Class C shares are offered in this Prospectus. Class X and
Class I shares are offered under separate prospectuses. The Class X shares has
different sales charges and other expenses, which may affect performance, and
may be purchased only by certain qualified investors (including, but not limited
to, IRAs, Roth IRAs, SEP IRAs, Simple IRAs and 403(b)(7) plans). The Class I
shares are sold without an initial sales charge and also are not subject to any
Rule 12b-1 fees, shareholder servicing fees or account servicing fees. The Class
I shares may be purchased only by (i) retirement plans affiliated with ING
Group, and (ii) ING Group and its affiliates for purposes of corporate cash
management. Each share class represents an ownership interest in the same
investment portfolio. When you choose your class of shares you should consider
the size of your investment and how long you plan to hold your shares.

     For example, if you buy Class A shares, you will be subject to a
distribution fee of 0.50% and a shareholder servicing fee of 0.25%.

     If you select Class B or C shares, you will be subject to a distribution
fee of 0.75% and a shareholder servicing fee of 0.25%. Because these fees are
paid out of the Fund's assets on an ongoing basis, over time these fees increase
the cost of your investment and may cost you more than purchasing the Class A
shares. In addition, you may be subject to a deferred sales load when you sell
Class B or Class C shares.

     The Funds' shares are distributed by ING Funds Distributor, Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Funds' shares may be
sold by retail broker-dealers that are under common control with the

 CLASS A SHARES

     No initial sales load is applied to Class A shares of any Fund in this
Prospectus.

 CLASS B SHARES - DEFERRED SALES LOAD ALTERNATIVE

     If you select Class B shares, you do not pay an initial sales load at the
time of purchase. However, if you redeem your Class B shares within 6 years
after purchase, you may be required to pay a deferred sales load. You will also
pay distribution fees of 0.75% and shareholder servicing fees of 0.25% each
year. Because these fees are paid out of a Fund's assets on an ongoing basis,
over time these fees increase the cost of your investment and may cost you more
than purchasing Class A shares. The Distributor uses the money that it receives
from the deferred sales loads and the distribution fees to cover the costs of
marketing, advertising and compensating the securities dealer who assists you in
purchasing Fund shares. Although Class B shares are sold without an initial
sales load, the Distributor normally pays a sales commission of 4.00% of the
purchase price of Class B shares to the dealer from its own resources at the
time of sale.

     If you redeem Class B shares within 6 years after purchase, you may be
charged a deferred sales load. The amount of the load gradually decreases as you
hold your shares over time, according to the following schedule:

<TABLE>
<CAPTION>
REDEMPTION DURING                          SALES LOAD*

</TABLE>

- ------------------------------

*   The sales load will apply to the lesser of the original cost of the shares
    being redeemed or the proceeds of your redemption. Shares acquired through
    reinvestment of dividends or distributions are not subject to a deferred
    sales load.

     The deferred sales load relating to Class B shares will be waived in
certain circumstances, such as:

     - Mandated minimum post-retirement withdrawals from an IRA or other
       retirement plan if you are over 59 1/2 years old.

     - Redemptions resulting from shareholder death or disability as long as the
       waiver request is made within one year of death or disability or, if
       later, reasonably promptly following completion of probate.
<PAGE>   105
ING FUNDS TRUST                                                                9
- --------------------------------------------------------------------------------

     - Redemptions through the Systematic Withdrawal Plan of up to 10% per year
       of the initial account balance, which must be at least equal to $20,000.

     - Redemptions resulting from closure by the Fund of the account in which
       shares are held.

     To determine whether the Class B CDSL applies to a redemption, the Fund
redeems shares in the following order: (i) shares acquired by reinvestment of
dividends and capital gains distributions; (ii) shares held for over six years;
and (iii) shares in the order they were purchased (such that shares held the
longest are redeemed first). In the table above, a "year" is a 12 month period.
All purchases are considered to have been made on the business day of the month
in which the purchase was made.

     Your Class B shares convert automatically into Class A shares eight years
after purchase. Any Class B shares received through reinvestment of dividends or
distributions paid on converting shares will also convert at that time. Class A
shares are subject to lower annual expenses than Class B shares. The conversion
of Class B shares to Class A shares is not a taxable event for federal income
tax purposes.

     If you redeem Class B shares and within 90 days buy new shares of the same
class, you will receive a credit for any CDSL paid. If such reinstated shares
are then redeemed within six years of the initial purchase, the CDSL will be
imposed upon the redemption. The amount eligible for this "Reinstatement
Privilege" may not exceed the amount of your redemption proceeds. To exercise
the privilege, contact the Funds at 1-877-INFO-ING.

 CLASS C SHARES -- LEVEL SALES LOAD ALTERNATIVE

     If you select Class C shares, you do not pay an initial sales load at the
time of purchase. However, if you redeem your Class C shares within one year
after purchase, you may be required to pay a deferred sales load. You will also
pay distribution fees of 0.75% and shareholder servicing fees of 0.25% each
year. Because these fees are paid out of a Fund's assets on an ongoing basis,
over time these fees increase the cost of your investment and may cost you more
than purchasing the Class A shares. The Distributor uses the money that it
receives from the deferred sales loads and the distribution fees to cover the
costs of marketing, advertising and compensating the securities dealer who
assists you in purchasing Fund shares. Although Class C shares are sold without
an initial sales load, the Distributor normally pays a sales commission of 1.00%
of the purchase price of Class C shares to the dealer from its own resources at
the time of sale.

     If you redeem Class C shares within one year after purchase, you may be
charged a deferred sales load of 1.00%. The charge will apply to the lesser of
the original cost of the shares being redeemed or the proceeds of your
redemption. You will not be charged a deferred sales load when you redeem shares
that you acquire through reinvestment of Fund dividends or distributions. The
deferred sales load relating to Class C shares will be reduced or waived in the
same circumstances as described for Class B shares above.

     Class C shares do not offer a conversion privilege.

     If you redeem Class C shares and within 90 days buy new shares of the same
class, you will receive a credit for any CDSL paid. If such reinstated shares
are then redeemed within one year of the initial purchase, the CDSL will be
imposed upon the redemption. The amount eligible for this "Reinstatement
Privilege" may not exceed the amount of your redemption proceeds. To exercise
the privilege, contact the Funds at 1-877-INFO-ING.

                             HOW TO PURCHASE SHARES

     Orders for the purchase of shares of the Funds will be executed at the net
asset value per share (the "public offering price") next determined after an
order has been received. The public offering price of each Fund is determined as
of the close of regular trading on the New York Stock Exchange (normally 4 p.m.
Eastern time) on each day the Exchange and the Federal Reserve Bank are open for
business.

     Notwithstanding the foregoing, a purchase order for shares of a Fund within
this Prospectus must generally be received by a specified "cut-off" time to be
executed on the same day at the price per share next determined, provided that
the Funds' custodian receives federal funds or other immediately available funds
by 4 p.m. Eastern time. The cut-off time applicable to the ING Money Market Fund
is 3:00 p.m. Eastern time and the cut-off time applicable to the ING U.S.
Treasury Money Market Fund and the ING National Tax-Exempt Money Market Fund is
12 noon Eastern time.

     The minimum initial investment in a Fund is $2,000 ($1,000 for an IRA
investment or any qualified plan). Any subsequent investments must be at least
$50, including an IRA or qualified plan investment. The Distributor may waive
these minimums from time to time. All initial investments should be accompanied
by a completed Account Application. An Account Application accompanies this
Prospectus. A separate application is required for an IRA or qualified plan
investor. All funds received are invested in full and fractional shares of the
appropriate Fund. Certificates for shares are not issued.

     When you purchase shares of a Fund, please specify the class of shares that
you wish to purchase. If you do not choose a class of shares, then your
investment will be made in Class A shares. The Funds reserve the right to reject
any purchase order. The Funds will accept third party checks from qualified
financial institutions, such as broker-dealers and investment advisers that are
registered with the Securities and Exchange Commission, as well as insurance
companies, banks, credit unions and thrift companies. Personal third party
checks and non-U.S. checks will not be accepted. All initial investments may be
made using any of the following methods:

     IRA investments made through the ING Auto-Asset Accumulation Plan or Direct
Deposit Plans will be treated as current year contributions only. Prior year
contributions through the ING Auto-Asset Accumulation Plan or Direct Deposit
Plans are prohibited. IRA investments cannot exceed Internal Revenue Service
stated maximums for investing in a calendar year. It is the account holder's
responsibility to ensure that their account(s) are within these maximum
investment guidelines.

                              HOW TO REDEEM SHARES

     You may redeem your shares, in whole or in part, on each day a Fund is
valued. Shares will be redeemed without charge (except for any applicable CDSL)
at the net asset value next determined after a redemption request in good order
has been received by the Funds. In the instance where you own more than one
class of shares and the class of shares being redeemed are not subject to the
CDSL, those shares with the highest Rule 12b-1 fee will be redeemed in full
prior to any redemption of shares with a lower Rule 12b-1 fee.

     When purchases are made by check in any Fund, redemption proceeds will be
made available immediately upon clearance of the purchase check, which may take
up to 15 calendar days. You may avoid this delay by investing through wire
transfers of federal funds.

     Once your shares are redeemed, the Funds will ordinarily send the proceeds
by check to you at the address of record on the next business day. To ensure
acceptance of your redemption request, it is important to follow the procedures
described below. If you purchased your shares through an Authorized Broker or
Investment Adviser, please contact them to inquire which redemption methods are
available to you. Under certain circumstances described below, a signature
guarantee may be required. You may redeem your shares using any of the following
methods:

  Optional Insurance Benefit     Insurance companies, including certain companies
                                 affiliated with the Manager, may make certain life
                                 insurance coverage available to persons on whose behalf
                                 shares of the Funds are purchased. The benefits of this
                                 coverage payable at death will be related to the amounts
                                 paid to purchase shares and to the value of the shares
                                 held for the benefit of the insured persons. If you
                                 purchase such life insurance coverage, you will be
                                 required to authorize periodic redemptions of Fund shares
                                 to pay the premiums for such coverage. These redemptions
                                 will not be subject to CDSLs, but will have the same tax
                                 consequences as any other Fund redemptions. Certain
                                 restrictions apply. Call 1-877-INFO-ING for more

     The Funds reserve the right to redeem in kind. That is, the Funds may honor
redemption requests with readily marketable portfolio securities instead of cash
if during any 90-day period redemptions exceed the lesser of $250,000 or 1% of
the net assets of the redeeming Fund at the beginning of such period. You may
incur transaction costs associated with converting these securities to cash.

     Due to the high costs of maintaining small accounts, the Funds may ask that
you increase your account balance if (1) the value of your account falls below
$500 for three consecutive months as a result of redemptions or exchanges, and
(2) your account has been in existence for at least one year and you have not
made any additional purchases in the account within the preceding six calendar
months. If the account balance remains below the minimum requirement for 60 days
after you are notified, the Funds may close your account and send you the
redemption proceeds.

     Signature Guarantees.  A signature guarantee is designed to protect the
investor, the Funds and their agents by verifying the signature of certain
investors seeking to redeem, transfer, or exchange shares of the Funds.
Signature guarantees are required for:

     - redemptions by mail in excess of $50,000;

     - redemptions by mail if the proceeds are to be paid to someone other than
       the name(s) in which the account is registered;

     - redemptions requesting proceeds to be sent by wire to other than the bank
       of record for the account;

any other class of the other Funds. Any sales load previously paid on the shares
being exchanged will be credited toward the sales load payable on the shares
being acquired. If a sales load has not been previously paid, then non-money
market shares being acquired may charge a sales load.

     Except as described below, Class B shares and Class C shares of a Fund may
be exchanged, based on the per share net asset values, for the same class of
shares of any other Fund. You will receive credit for the period of time you
held the shares being exchanged when determining whether the acquired shares,
when redeemed, will be subject to a contingent deferred sales load.
     Your exchange will be processed at the next determined net asset value (or
offering price, if there is a sales load) after the Funds receive your request.
A new account opened by exchange must be established with the same name(s),
address and social security number as the existing account.

     You may only exchange shares into a Fund which is authorized for sale in
your state of residence. The Funds may limit each account to eight exchanges per
calendar year. The Funds may change or discontinue the exchange privilege after
giving you 60 days' prior notice. An exchange of shares is a taxable event on
which you may realize a gain or loss. You may exchange shares using any of the
following methods:

</TABLE>

                               PRICING OF SHARES

     Each of the Funds prices its shares based on its net asset value. The Funds
use the amortized cost method to value its portfolio securities and seek to
maintain a constant net asset value of $1.00 per share, although there may be
circumstances under which this goal cannot be achieved. The amortized cost
method involves valuing a security at its cost and amortizing any discount or
premium over the period until maturity, regardless of the impact of fluctuating
interest rates on the market value of the security. Although the Board of
Trustees has established procedures designed to stabilize, to the extent
reasonably possible, the share price of the Funds, there can be no assurance
that each Fund's net asset value can be maintained at $1.00 per share.

     Each Fund determines the net asset value of its shares as of the close of
the NYSE (normally 4:00 p.m., Eastern time) on each day the NYSE and the Federal
Reserve Bank are open for business. The price at which a purchase or redemption
is effected is based on the next calculation of a Fund's net asset value after
the order is placed.

                          DIVIDENDS AND DISTRIBUTIONS

     Each Fund intends to distribute to its shareholders substantially all of
its investment company taxable income (which includes dividends and interest and
the excess, if any, of net short-term capital gains over net long-term capital
losses). Each of the Funds will declare dividends daily and pay dividends
monthly. In addition, each Fund intends to distribute, at least annually,
substantially all of its net capital gains (the excess of net long-term capital
gains over net short-term capital losses). In determining amounts of capital
gains to be distributed, any capital loss carryovers from prior years will be
applied against capital gains.

     Dividends and distributions will be reinvested in additional shares of a
Fund at net asset value unless you elect to receive such dividends and
distributions in cash. If you redeem all or a portion of Fund shares prior to a
dividend payment date, you will be entitled on the next dividend payment date to
all dividends declared but unpaid on those shares at the time of their
redemption.

     If you elect to receive distributions in cash and the post office cannot
deliver your checks or if you do not cash your checks within six months, your
dividends may be reinvested in your account at the then-current net asset value
and your account will be converted to the reinvestment option. You will not
receive interest on the amount of your uncashed checks.

     You may also elect to automatically invest dividends and distributions paid
by a Fund in shares of any other ING Fund of which you are a shareholder. Shares
of the other Fund will be purchased at that Fund's then-current net asset value.

     You may also elect to transfer electronically dividends and distributions
paid by a Fund to your designated bank account if your financial institution is
an Automated Clearing House member. Banks may charge a fee for the service.

     The elections described above may be made either on the Account Application
or by calling the Fund at 1-877-INFO-ING.

                                     TAXES

     All Funds.  Each Fund is treated as a separate entity for federal income
tax purposes. Each Fund intends to qualify as a regulated investment company by
satisfying the requirements under Subchapter M of the Internal Revenue
<PAGE>   112
 16                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

Code of 1986 (the "Code"), including requirements with respect to
diversification of assets, distribution of income and sources of income. By so
qualifying, each Fund generally will not be subject to federal income tax to the
extent that it distributes investment company taxable income and net realized
capital gains in the manner required under the Code.

     Distributions by a Fund of its taxable net investment income and the
excess, if any, of its net short-term capital gain over its net long-term
capital loss are taxable to shareholders as ordinary income. Distributions by a
Fund of the excess, if any, of its net long-term capital gain over its net
short-term capital loss are designated as capital gain dividends and are taxable
as long-term capital gains, regardless of the length of time you have held your
shares.

     Distributions will be treated in the same manner for federal income tax
purposes whether you receive them in cash or reinvest them in additional shares
of the Fund. In general, distributions by a Fund are taxable to you in the year
in which the distributions are made. However, certain distributions made during
January will be treated as having been paid by a Fund and received by you on
December 31 of the preceding year.

     A redemption or an exchange of shares is a taxable transaction on which you
may realize a gain or loss. Any gain or loss realized upon the sale or other
disposition of shares of a Fund generally will be a capital gain or loss which
will be long-term or short-term depending on how long you have held the shares.

     Any loss realized upon a sale or disposition of shares within six months
from the date of their purchase will be treated as a long-term capital loss to
the extent of any capital gain distributions received on such shares.

     Under the backup withholding rules of the Code, you may be subject to 31%
withholding of federal income tax on ordinary income dividends paid by a Fund.
In order to avoid this backup withholding, you must provide the Funds with a
correct taxpayer identification number or certify that you are otherwise exempt
from or not subject to backup withholding.

     You will be notified annually as to the federal tax status of distributions
made by the Funds in which you invest. Depending on your residence for tax
purposes, distributions also may be subject to state and local taxes. You should
consult your own tax advisor as to the federal, state and local tax consequences
of investing in shares of the Funds in your particular circumstances.

     ING National Tax-Exempt Money Market Fund.  If the ING National Tax-Exempt
Money Market Fund complies with applicable requirements of the Code, then
dividends derived from interest on qualified state and local bonds ("tax-exempt
bonds") will constitute exempt-interest dividends and will not be subject to
federal income tax. Some portion of the exempt-interest dividends paid by the
Fund could be treated as an item of "tax preference" for purposes of the
alternative minimum tax. Under the Code, interest on certain types of tax-exempt
bonds is designated as an item of tax preference for purposes of the alternative
minimum tax on individuals and corporations. Therefore, if the Fund were to
invest in such types of bonds, you would be required to treat as an item of tax
preference that part of the distributions by the Fund that is derived from
interest income on such bonds.

     Entities or persons who are "substantial users" (or persons related
thereto), as defined in the Code, of facilities financed by tax-exempt bonds
issued for certain private activities should consult their tax advisor before
purchasing shares of the Fund.

     You are required to report the amount of tax-exempt interest received each
year, including exempt-interest dividends paid by the Fund, on your federal
income tax return. Exempt-interest dividends and other distributions paid by the
Fund are included in the tax base for determining the taxability of social
security or railroad retirement benefits. Interest on debt incurred to purchase
or carry shares of the Fund may not be deductible for federal income tax
purposes.

                  MORE INFORMATION ABOUT STRATEGIES AND RISKS

     A Fund's risk profile is largely a factor of the principal securities in
which it invests and investment techniques that it uses. The following pages
discuss the risks associated with certain of the types of securities in which
the Funds may invest and certain of the investment practices that the Funds may
use. For more information about these and other types of securities and
investment techniques used by the Funds, see the Statement of Additional
Information. Unless indicated otherwise, the following descriptions apply to all
Funds.

     Many of the investment techniques and strategies discussed in this
Prospectus and in the Statement of Additional Information are discretionary,
which means that the Investment Manager or Sub-Adviser can decide whether to use
them or not. The Investment Manager or Sub-Adviser may also use investment
techniques or make investments in securities that are not a part of the Fund's
principal investment strategy.
<PAGE>   113
ING FUNDS TRUST                                                               17

     Corporate and Municipal Debt Securities (ING Money Market Fund and ING
National Tax-Exempt Money Market Fund, respectively).  Debt securities are
subject to the risk of the issuer's inability to meet principal and interest
payments on the obligation and may also be subject to price volatility due to
such factors as interest rate sensitivity, market perception of the
credit-worthiness of the issuer and general market liquidity. When interest
rates decline, the value of the debt securities can be expected to rise, and
when interest rates rise, the value of those securities can be expected to
decline. Debt securities with longer maturities tend to be more sensitive to
interest rate movements than those with shorter maturities.

     U.S. Government Agency Securities (ING Money Market Fund Only).  Some U.S.
Government agency securities may be subject to varying degrees of credit risk,
and all U.S. Government securities may be subject to price declines in the
securities due to changing interest rates.

     Other Investment Companies (All Funds).  Each Fund may invest up to 10% of
its assets in other unaffiliated investment companies. There is no limit with
regard to investments in affiliated investment companies. When a Fund invests in
other investment companies, you indirectly pay a proportionate share of the
expenses of that other investment company (including management fees,
administration fees, and custodial fees) in addition to the expenses of the
Fund.

     Restricted and Illiquid Securities (All Funds, except ING U.S. Treasury
Money Market Fund).  Each Fund may invest up to 10% of its net assets in
restricted and illiquid securities. If a security is illiquid, the Fund might be
unable to sell the security at a time when the sub-adviser might wish to sell,
and the security could have the effect of decreasing the overall level of the
Fund's liquidity. Further, the lack of an established secondary market may make
it more difficult to value illiquid securities, which could vary from the amount
the Fund could realize upon disposition. Restricted securities, i.e., securities
subject to legal or contractual restrictions on resale, may be illiquid.
However, some restricted securities may be treated as liquid, although they may
be less liquid than registered securities traded on established secondary
markets.

     Mortgage-Related Securities (ING Money Market Fund Only).  Like other fixed
income securities, when interest rates rise, the value of a mortgage-backed
security generally will decline; however, when interest rates are declining, the
value of mortgage-backed securities with prepayment features may not increase as
much as other fixed income securities. The rate of prepayments on underlying
mortgages will affect the price and volatility of a mortgage-related security,
and may have the effect of shortening or extending the effective maturity of the
security beyond what was anticipated at the time of the purchase. Unanticipated
rates of prepayment on underlying mortgages can be expected to increase the
volatility of such securities. In addition, the value of these securities may
fluctuate in response to the market's perception of the creditworthiness of the
issuers of mortgage-related securities owned by a Fund. Additionally, although
mortgages and mortgage-related securities are generally supported by some form
of government or private guarantee and/or insurance, there is no assurance that
private guarantors or insurers will be able to meet their obligations.

     Asset-Backed Securities (ING Money Market Fund Only).  Asset-backed
securities involve certain risks that are not posed by mortgage-related
securities, resulting mainly from the fact that asset-backed securities often do
not contain the benefit of a complete security interest in the related
collateral. The risks associated with asset-backed securities may be reduced by
the addition of credit enhancements such as a bank letter of credit or a
third-party guarantee.

     Repurchase Agreements (All Funds).  Each Fund may enter into repurchase
agreements, which involve the purchase by a Fund of a security that the seller
has agreed to buy back. If the seller defaults and the collateral value
declines, the Fund might incur a loss. If the seller declares bankruptcy, the
Fund may not be able to sell the collateral at the desired time.

     Lending Portfolio Securities (All Funds).  In order to generate additional
income, each Fund may lend portfolio securities in an amount up to 33 1/3% of
its total assets to broker-dealers, major banks, or other recognized domestic
institutional borrowers of securities. As with other extensions of credit, there
are risks of delay in recovery or even loss of rights in the collateral should
the borrower default or fail financially.

     Borrowing (All Funds).  Each Fund may borrow for certain types of temporary
or emergency purposes subject to certain limits. Borrowing may exaggerate the
effect of any increase or decrease in the value of portfolio securities or the
net asset value of a Fund, and money borrowed will be subject to interest costs.
Interest costs on borrowings may fluctuate with changing market rates of
interest and may partially offset or exceed the return earned on borrowed funds.
Under adverse market conditions, a Fund might have to sell portfolio securities
to meet interest or principal payments at a time when fundamental investment
considerations would not favor such sales.

     Fundamental and Non-Fundamental Policies (All Funds).  Unless otherwise
stated, all investment objectives and policies are non-fundamental and may be
amended without shareholder approval.

     Percentage Investment Limitations (All Funds).  Unless otherwise stated,
percentage limitations in this prospectus apply at the time of investment.

                              FINANCIAL HIGHLIGHTS

     The financial highlights table is intended to help you understand the ING
Money Market Fund's financial performance for the fiscal period ended October
31, 1999. Certain information reflects financial results for a single Fund
share. The total returns in the table represent the rate than an investor would
have earned or lost on an investment in the Fund (assuming reinvestment of all
dividends and distributions). Past performance does not guarantee future
results. This information has been audited by Ernst & Young LLP, independent
auditors, whose report, along with the Fund's financial statements, is included
in the Statement of Additional Information, which is available upon request.
Because the following Funds had not commenced operations prior to October 31,
1999, financial highlights are not presented for ING U.S. Treasury Money Market
Fund and National Tax-Exempt Money Market Fund.

- --------------------------------------------------------------------------------

                                  STOCK FUNDS

 ING LARGE CAP GROWTH FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and will invest at least 65% of its total
assets in a portfolio of equity securities of large companies (that is,
companies with market capitalizations of more than $1 billion at the time of
acquisition), which in the Sub-Adviser's opinion possess growth potential. As a
general matter, the Fund expects these investments to be in common stocks.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, four-step investment process that seeks to identify unrecognized
growth and value in large capitalization stocks. The four steps are:

     - First, the universe of companies is screened using models developed by
       the Sub-Adviser to create a list of possible investments;

     - Second, the Sub-Adviser researches the companies identified by the
       screening models. This research includes a review of company management
       and other factors that are more subjective and require the extensive
       practical experience of the portfolio managers;

     - Third, the Sub-Adviser evaluates the return, valuation and risk of the
       remaining potential investments against a defined peer group; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities. The Fund invests primarily in equity
       securities of larger companies, which generally have more stable prices
       than smaller companies.

     - Market Trends.  From time to time, the stock market may not favor the
       large company, growth-oriented securities in which the Fund invests.
       Rather, the market could favor value stocks or small company stocks, or
       may not favor equities at all.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class X shares would have
substantially similar annual returns because the Class X shares are invested in
the same portfolio of securities and the annual returns would differ only to the
extent that Class X shares and Class A shares do not have the same expenses. For
purposes of the Average Annual Returns table, Class A shares' return reflects a
deduction of an initial sales load.

ANNUAL TOTAL RETURNS

     The following bar chart depicts changes in the performance of the Fund's
Class A shares for the year ended December 31, 1999. The bar chart does not
reflect sales loads. If it did, the annual total returns shown would be lower.

 ING GROWTH & INCOME FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities. As a general matter, the Fund expects these
investments to earn income and to be in common stocks of large companies whose
market capitalizations are generally in excess of $10 billion.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, three-step investment process that seeks to identify growth at a
reasonable price. The three steps are:

     - First, the universe of companies is screened using models developed by
       the Sub-Adviser to rank possible investments;

     - Second, the Sub-Adviser researches the companies identified by the
       screening models. This research includes a review of earnings, sales and
       growth, as well as the impact of broad economic trends found within the
       economy upon possible investments;

     - Third, in order to help manage the risk of the portfolio, the
       characteristics of the portfolio are evaluated against certain market
       benchmarks.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Changes in Interest Rates.  The Fund invests in securities that produce
       income and therefore the value of its investments may rise or fall in
       response to fluctuations in interest rates. Generally, when interest
       rates increase, the value of income producing securities may decrease,
       and when interest rates decrease, the value of income producing
       securities may increase.

     - Market Trends.  From time to time, the stock market may not favor the
       income producing securities in which the Fund invests. Rather, the market
       could favor non-income producing large capitalization growth stocks,
       value stocks or small company stocks, or may not favor equities at all.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class X shares would have
substantially similar annual returns because the Class X shares are invested in
the same portfolio of securities and the annual returns would differ only to the
extent that Class X shares and Class A shares do not have the same expenses. For
purposes of the Average Annual Returns table, Class A shares' return reflects a
deduction of an initial sales load.

 ING MID CAP GROWTH FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of companies with market capitalizations
falling within the Russell Mid Cap Growth Index at the time of acquisition
which, in the Sub-Adviser's opinion, possess growth potential. The average
market capitalization and median market capitalization of this index as of its
latest reconstitution was $4.13 billion and $3.15 billion, respectively. As a
general matter, the Fund expects these investments to be in common stocks.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined investment process combining technical analysis and fundamental
research that seeks to identify companies with superior growth characteristics.
The Sub-Adviser also follows certain self-imposed criteria in an attempt to
manage risk.

     QUANTITATIVE ANALYSIS evaluates stocks based on:

     - Market capitalizations (their size based on price and shares outstanding)

     - Minimum stock price

     - Trading history

     - Trading volume

     - Earnings growth

     - Relative financial strength

     FUNDAMENTAL RESEARCH of individual companies emphasizes:

     - Sustainable earnings growth potential

     - Strong balance sheets

     - Cash flow characteristics

     - Reasonable valuations

     - Quality management

     RISK MANAGEMENT discipline stresses:

     - Remaining fully invested at all times

     - Broad diversification among securities and industries

     - Strict adherence to established buy and sell criteria

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
<PAGE>   124
ING FUNDS TRUST                                                                7
- --------------------------------------------------------------------------------

       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       mid-capitalization company, growth-oriented securities in which the Fund
       invests. Rather, the market could favor value stocks or stocks of larger
       or smaller companies, or may not favor equities at all.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class X shares would have
substantially similar annual returns because the Class X shares are invested in
the same portfolio of securities and the annual returns would differ only to the

 ING SMALL CAP GROWTH FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of smaller companies (that is, companies
with market capitalizations falling within the Russell 2500 Growth Index at the
time of acquisition), which in the Sub-Adviser's opinion possess growth
potential. The average market capitalization and median market capitalization of
this index as of its latest reconstitution was $870 million and $580 million,
respectively. As a general matter, the Fund expects these investments to be in
common stocks.

     In choosing investments for the Fund, the Sub-Adviser employs a disciplined
investment process that combines economic analysis and extensive company
research to identify companies with superior long-term growth potential. The
investment strategy of the Sub-Adviser is as follows:

     - The Sub-Adviser reviews economic and industry trends to develop themes to
       use in the development of the overall portfolio, which in turn helps
       identify specific companies to consider.

     - With regard to companies under consideration, the Sub-Adviser next
       reviews their respective business models and management, and meets with
       senior executives. The Sub-Adviser also analyzes the

- --------------------------------------------------------------------------------

       company's price-to-earnings ratios, earnings forecasts and cash flow.

     - Companies that do not meet the expectations of the Sub-Adviser, either
       due to earnings disappointments or other fundamental criteria may be
       sold.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       small company, growth-oriented securities in which the Fund invests.
       Rather, the market could favor value stocks or large company stocks, or
       may not favor equities at all.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class X shares would have

 ING GLOBAL BRAND NAMES FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of companies which in the
Sub-Adviser's opinion, have a well recognized franchise, a global presence and
derive most of their revenues from sales of consumer
<PAGE>   126
ING FUNDS TRUST                                                                9
- --------------------------------------------------------------------------------

goods. The companies in which the Fund invests either have leading market
positions, or in the Sub-Adviser's opinion, have the potential to achieve
leading market positions in the foreseeable future. This portion of the
portfolio will have investments located in at least three different countries
including the United States. As a general matter, the Fund expects these
investments to be in common stocks of large companies whose market
capitalizations are generally in excess of $10 billion.

     In choosing investments for the Fund, the Sub-Adviser believes that
well-established companies with strong brand names offer the following
investment advantages:

     - First, demand for brand name products should rise as global consumer
       tastes become more uniform;

     - Second, large companies that can leverage doing business on a larger
       scale have enhanced profit potential;

     - Third, perceived product quality and reliability facilitates sales;

     - Fourth, greater recognition leads to brand loyalty; and

     - Finally, brand extensions, or the ability to leverage a company's
       established brand, provide opportunities for growth.

     The Sub-Adviser employs a two-tiered approach to structuring the Fund's
portfolio with securities that offer growth at a reasonable price. The first
tier, which will comprise about 75% of the portfolio, is composed of core stocks
with stable earnings development, low cyclicality, large market capitalizations
and longer-term investment horizons. The second tier, which will comprise about
25% of the portfolio, is composed of companies possessing higher cyclicality,
smaller market capitalizations and shorter-term investment horizons. This second
tier is expected to provide the Fund with shorter-term performance benefits.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. Rather, the market could favor
       value stocks or small company stocks, or may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

annual returns and long-term performance. The Fund's past performance is not an

 ING INTERNATIONAL EQUITY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of issuers organized or having a majority of
their assets in or deriving a majority of their operating income in any country
throughout the world, not including the United States. This portion of the
portfolio will have investments in at least seven different countries. The Fund
may purchase securities in any foreign country, developed or underdeveloped, or
emerging market countries. The Fund will not invest more than 15% of its total
assets in emerging market countries.

     As a general matter, the Fund expects these investments to be in common
stocks of large companies whose market capitalizations are generally in excess
of $10 billion. The Fund may also use options and futures contracts involving
foreign currencies.

     In choosing investments for the Fund, the Sub-Advisers employ a highly
disciplined, four-step investment process combining top-down country allocations
with bottom-up fundamental research that seeks to identify companies which will
provide superior relative returns. The four steps are:

     - First, the Sub-Advisers perform a comprehensive analysis of the relative
       value of geographic regions to determine the degree of representation of
       such geographic regions in the Fund's portfolio;

     - Second, such determinations are reviewed by an independent committee
       within the Sub-Advisers;

     - Third, the Sub-Advisers select investments within the selected
       geographical regions based on comprehensive fundamental analysis; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       stocks in markets to which the Fund is not exposed, or may not favor
       equities at all.

- --------------------------------------------------------------------------------

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Emerging Market Risk.  To the extent the Fund invests in emerging markets
       countries, the risks may be greater, partly because emerging market
       countries may be less politically and economically stable than other
       countries. It may also be more difficult to buy and sell securities in
       emerging market countries.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class X shares would have
substantially similar annual returns because the Class X shares are invested in
the same portfolio of securities and the annual returns would differ only to the
extent that Class X shares and Class A shares do not have the same expenses. For
purposes of the Average Annual Returns table, Class A shares' return reflects a
deduction of an initial sales load.

 ING EUROPEAN EQUITY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of European issuers. The Sub-Adviser
considers European issuers to be companies whose securities are principally
traded in the European capital markets, that derive at least 50% of their total
revenues or earnings from either goods produced or services rendered in
countries located in Europe, regardless of where the securities of such
companies are principally traded, or that are organized under the laws of and
have a principal office in a European country. As a general matter, the Fund
expects these investments to be in common stocks of large companies whose market
capitalizations are generally in excess of $10 billion.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, five-step investment process that seeks to identify underpriced
earnings growth in European companies. The five steps are:

     - First, the Sub-Adviser ranks possible investments according to trading
       volume and liquidity relative to their peers.

     - Second, the Sub-Adviser performs additional screens to determine which
       companies should be further researched;
<PAGE>   129

- --------------------------------------------------------------------------------

     - Third, the Sub-Adviser performs fundamental analysis of cyclical and
       non-cyclical market sectors and companies to identify underpriced
       earnings or cash flow growth.

     - Fourth, the Sub-Adviser determines portfolio weightings within each
       sector.

     - Finally, the Sub-Adviser continuously monitors the portfolio to maintain
       favorable risk-reward relationships.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in markets to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the

 ING TAX EFFICIENT EQUITY FUND

     Investment Objective.  The Fund seeks to provide taxable investors with a
high total return on an after-tax basis.
<PAGE>   130
ING FUNDS TRUST                                                               13
- --------------------------------------------------------------------------------

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 80% of its total assets
in a portfolio of equity securities whose returns depend upon stock market
prices. The Sub-Adviser will manage the Fund's portfolio in a manner that will
attempt to reduce net realized capital gains each year. An emphasis will be
placed on common stocks of companies which the Sub-Adviser believes to have
superior appreciation potential. As a general matter, the Fund expects these
investments to be in common stocks of large, mid-sized, and small companies.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined investment process, combining macroeconomic analysis and fundamental
company research that seeks to identify growth at a reasonable price:

     - The Sub-Adviser first determines the outlook for market sectors and
       industries based on business cycle characteristics.

     - The Sub-Adviser next searches for companies with improving fundamentals
       and accelerating growth.

     - Finally, the Sub-Adviser assesses company stock prices relative to their
       expected earnings growth rates and to the overall equity markets.

     The Sub-Adviser attempts to minimize tax consequences to investors by
focusing on non-dividend paying or low-dividend paying stocks and by reducing
annual portfolio turnover.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An

       the Fund's underlying investments decrease. Equity securities face

       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or small company stocks, or may not favor equities at all.

     - Tax Efficient Management.  The Fund is managed to provide high after-tax
       returns. Therefore, it may not provide as high a return before tax as
       other funds, and as a result may not be suitable for investors who are
       not subject to current income tax (for example, those investing through a
       tax-deferred retirement account, such as an IRA or a 401(k) Plan).

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an

 ING TAX EFFICIENT EQUITY VALUE FUND

     Investment Objective.  The Fund seeks to provide taxable investors with a
high total return on an after-tax basis.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 80% of its total assets
in a portfolio of equity securities determined by the Sub-Advisers to be
undervalued in the marketplace and whose returns depend upon stock market
prices. Such companies generally will have one or more of the following
attributes: (i) valuable fixed assets; (ii) valuable consumer or commercial
franchises; (iii) selling at low market valuations of assets relative to the
securities market in general, or companies that may currently be earning a very
low return on assets but which have the potential to earn higher returns if
conditions in the industry improve; (iv) are undervalued in relation to their
potential for growth in earnings, dividends, and book value; or (v) have
recently changed management or control and have the potential for a "turnaround"
in earnings. The Sub-Advisers will manage the Fund's portfolio in a manner that
will attempt to reduce net realized capital gains each year. As a general
matter, the Fund expects these investments to be in common stocks of large,
mid-sized, and small companies.

     In choosing investments for the Fund, the Sub-Advisers employ a highly
disciplined investment process, combining macroeconomic analysis and fundamental
company research that seeks to identify undervalued companies:

     - The Sub-Advisers first determines the outlook for market sectors and
       industries based on business cycle characteristics.

       associated with larger, more established companies due to the greater
       business risks of smaller size, more limited markets and financial

 ING FOCUS FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest in a portfolio of 20 to 40
equity securities. As a general matter, the Fund expects these investments to be
in common stocks of large, mid-sized, and small companies.

     The Sub-Adviser seeks to invest the Fund in growth companies that are
positioned to benefit from capitalizing on significant industry, regulatory,
technological, and ownership changes. To find such companies, the Sub-Adviser
looks for management teams with entrepreneurial spirit and a proven talent for
creating value, with a focus on industries expected to drive change in other
industries (for example, technology and financial services). The Sub-Adviser's
investment strategy incorporates the following elements to identify companies
that offer growth at a reasonable price:

     - The Sub-Adviser performs fundamental economic and business research to
       identify investment themes expected to improve returns on capital and
       drive earnings growth within industries.

     - The Sub-Adviser next analyzes individual companies to identify favorable:

       -- Business characteristics, including industry structure and trends

       -- Financial performance, both historical and projected

       -- Valuations in both absolute and relative terms

     - The Sub-Adviser continues to monitor previously identified companies to
       track changes in critical variables as well as price fluctuations.

     - The Sub-Adviser sets specific limits on individual holdings and sector
       concentrations.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets
<PAGE>   133

- --------------------------------------------------------------------------------

       and financial resources, narrow product lines and the frequent lack of
       depth of management. The securities of smaller companies may be subject
       to more abrupt or erratic market movements than securities of larger,
       more established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       growth-oriented securities in which the Fund invests. Rather, the market
       could favor value stocks or small company stocks, or may not favor
       equities at all.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class X shares would have
substantially similar annual returns because the Class X shares are invested in
the same portfolio of securities and the annual returns would differ only to the
extent that Class X shares and Class A shares do not have the same expenses. For
purposes of the Average Annual Returns table, Class A shares' return reflects a
deduction of an initial sales load.

ANNUAL TOTAL RETURNS

     The following bar chart depicts changes in the performance of the Fund's
Class A shares for the year ended December 31, 1999. The bar chart does not
reflect sales loads. If it did, the annual total returns shown would be lower.

 ING GLOBAL INFORMATION TECHNOLOGY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of information technology companies. The
Fund defines information technology companies as those companies that derive at
least 50% of their total revenues or earnings from information technology,
hardware or software, or related consulting and services industries. This
portion of the portfolio will have investments located in at least three
different countries, including the United States. As a general matter, the Fund
expects these investments to be in common stocks of large, mid-sized, and small
companies.

     The Sub-Adviser believes that because of rapid advances in information
technology, investment in companies within this sector should offer substantial
opportunities for long-term capital appreciation. The information technology
area has exhibited and continues to demonstrate rapid growth, both through
increasing demand for existing products and services and the broadening of the
technology market. Generally, the Sub-Adviser's overall stock selection for the
Fund will be based on an assessment of the company's fundamental prospects. The
Sub-Adviser anticipates, however, that a portion of the Fund's holdings will be
invested in newly issued securities being sold in the primary or secondary
market.

- --------------------------------------------------------------------------------

     The Sub-Adviser combines broad industry analysis and bottom-up company
analysis to identify the stocks of companies it believes will become tomorrow's
information technology leaders. In choosing investments for the Fund, the
Sub-Adviser first identifies themes that address industry and technological
changes. Using intensive fundamental research, the Sub-Adviser then analyzes
individual companies worldwide to find those firms most likely to benefit from
the selected investment themes.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in industries to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to a particular industry, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives.

     - Information Technology Risk.  Information technology companies are
       generally subject to the rate of change in technology, which is higher
       than other industries. In addition, products and services of companies
       engaged in the information technology industry are subject to relatively
       high risks of rapid obsolescence caused by scientific and technological
       advances. Swings in investor psychology or significant trading by large
       institutional investors can result in significant price fluctuations and
       stock price declines.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class X shares would have

 ING GLOBAL COMMUNICATIONS FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of communications companies. This portion of
the portfolio will have investments located in at least three different
countries, including the United States. As a general matter, the Fund expects
these investments to be in common stocks of large, mid-sized, and small
companies.

     The Fund considers communications companies to be those that derive at
least 50% of their total revenues or earnings from designing, developing,
operating, financing, manufacturing or providing the following activities,
products and services: communications equipment and service (including equipment
and services for both data and voice transmission); electronic components and
equipment; broadcast (including television and radio, satellite, microwave and
cable television); computer equipment, mobile telecommunications and cellular
radio and paging; electronic mail; local and wide area networking and linkage of
work and data processing systems (collectively, "communications activities").

     The Sub-Adviser believes that because of rapid advances in communications,
investment in companies within this sector should offer substantial
opportunities for long-term capital appreciation. The communications area has
exhibited and continues to demonstrate rapid growth, both through increasing
demand for existing products and services and the broadening of the technology
market. Generally, the Sub-Adviser's overall stock selection for the Fund will
be based on an assessment of the company's fundamental prospects. The
Sub-Adviser anticipates, however, that a portion of the Fund's holdings will be
invested in newly issued securities being sold in the primary or secondary

     The Sub-Adviser combines broad industry analysis and bottom-up company
analysis to identify the stocks of companies it believes will become tomorrow's
communications leaders. In choosing investments for the Fund, the Sub-Adviser

       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of

       volatile market movements than securities of larger, more established

     - Small Companies.  Investments in small companies involve greater risk

       the communications industry are subject to relatively high risks of rapid
       obsolescence caused by scientific and technological advances. Swings in
       investor psychology or significant trading by large institutional
       investors can result in significant price fluctuations and stock price
       declines.

     - Governmental Regulation.  Certain communications industries, such as the
       telecommunications industry, may be subject to greater governmental
       regulation than many other industries. Accordingly, such industries may
       be subject to changes in governmental policies and the need for
       regulatory approvals may have a material effect on the products and
       services offered. Telephone operating companies in the United States, for
       example, are subject to both federal and state regulation affecting
       permitted rates of return and the kinds of services that may be offered.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Global
Communications Fund has not yet commenced operations, there is no performance
information included in this Prospectus.

 ING INTERNET FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of U.S. and non-U.S. internet
technology companies. The Fund defines internet technology companies as those
companies with internet businesses or internet related consulting or services
businesses, or that derive at least 50% of their total revenues or earnings from
business operations in internet related hardware, software or infrastructure
industries. As a general matter, the Fund expects these investments to be in
common stocks of large, mid-sized, and small companies.

     The Sub-Adviser believes that the internet is in the early stages of a
period of promising growth. The internet has enabled companies to tap into new
markets, use new distribution channels and do business with end users of their
products all over the world without having to go through wholesalers and
distributors. The Sub-Adviser believes that investment in companies related to
the internet should offer substantial opportunities for long-term capital
appreciation. Generally, the Sub-Adviser's overall stock selection for the Fund
will be based on an assessment of a company's fundamental prospects. The
Sub-Adviser anticipates, however, that a portion of the Fund's holdings will be
invested in newly issued securities being sold in the primary or secondary
market.

     In choosing investments for the Fund, the Sub-Adviser first identifies
themes which it believes will drive the internet in the future. Then, by
conducting extensive fundamental research, the Sub-Adviser analyzes individual

       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to a particular industry, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives.

     - Internet Technology Risk.  Internet and internet-related companies are
       generally subject to the rate of change in technology, which is higher
       than other industries. In addition, products and services of companies
       engaged in internet and internet-related activities are subject to
       relatively high risks of rapid obsolescence caused by scientific and
       technological advances. Swings in investor psychology or significant
       trading by large institutional investors can result in significant price
       fluctuations and stock price declines.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Internet Fund
commenced operations on July 1, 1999, there is no performance information
included in this Prospectus.

 ING INTERNET FUND II

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of U.S. and non-U.S. internet
technology companies. The Fund defines internet technology companies as those
companies with internet businesses or internet related consulting or services
businesses, or that derive at least 50% of their total revenues and earnings
from business operations in internet related hardware, software or
infrastructure industries. As a general matter, the Fund expects these
investments to be in common stocks of large, mid-sized, and small companies.

     The Sub-Adviser believes that the internet is in the early stages of a
period of promising growth. The internet has enabled companies to tap into new
markets, use new

ING FUNDS TRUST                                                               21
- --------------------------------------------------------------------------------

distribution channels and do business with end users of their products all over
the world without having to go through wholesalers and distributors. The
Sub-Adviser believes that investment in companies related to the internet should
offer substantial opportunities for long-term capital appreciation. Generally,
the Sub-Adviser's overall stock selection for the Fund will be based on an
assessment of a company's fundamental prospects. The Sub-Adviser anticipates,
however, that a portion of the Fund's holdings will be invested in newly issued
securities being sold in the primary or secondary market.

     In choosing investments for the Fund, the Sub-Adviser first identifies
themes which it believes will drive the internet in the future. Then, by
conducting extensive fundamental research, the Sub-Adviser analyzes individual
companies worldwide to identify those firms that are most likely to benefit from
the selected investment themes.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in industries to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to a particular industry, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives.

     - Internet Technology Risk.  Internet and internet-related companies are
       generally subject to the rate of change in technology, which is higher
       than other industries. In addition, products and services of companies
       engaged in internet and internet-related activities are subject to
       relatively high risks of rapid obsolescence caused by scientific and
       technological advances. Swings in investor psychology or significant
       trading by large institutional investors can result in significant price
       fluctuations and stock price declines.

 ING BALANCED FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  The Fund primarily invests in a
combination of mid- and large-capitalization equity securities, intermediate
maturity fixed income securities and money market instruments. Equity
securities, which include common and preferred stocks, warrants and convertible
securities, are acquired for capital appreciation or a combination of capital
appreciation and income. Fixed income securities, which include investment grade
corporate debt obligations (for example, rated at least BBB by Standard & Poor's
Rating Group or Baa by Moody's Investor Services) and U.S. Government
securities, are acquired for income and secondarily for capital appreciation.
Money market instruments mature in 13 months or less from the date of purchase
and include U.S. Government securities and corporate debt securities (including
those subject to repurchase agreements), certificates of deposit, bankers
acceptances and commercial paper. The Fund may also invest in mortgage-backed
securities and asset-backed debt securities and use options and futures
contracts involving securities, securities indices, and interest rates. The Fund
will operate as a diversified fund.

     The percentage of assets invested in equities, fixed income securities and
money market instruments will vary from time to time depending upon the
Sub-Adviser's judgment of general market and economic conditions, trends in
yields and interest rates and changes in fiscal or monetary policies. Depending
upon the Sub-Adviser's determination of market and economic conditions,
investment emphasis may be placed on equities or fixed income securities. The
allocation between equities and fixed income securities creates an opportunity
for investors to receive competitive returns of capital growth and income while
maintaining diversification. Under normal market conditions, the Fund will
invest at least 25% of its total assets in fixed income securities. The average
maturity of the fixed income securities held by the Fund will normally
approximate five years, although this will vary with changing market conditions
and opportunities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Equity Investments.  Equity securities face market, issuer and
       other risks, and their values may go down, sometimes rapidly and
       unpredictably. Market risk is the risk that securities may decline in
       value due to factors affecting securities markets generally or particular
       industries. Issuer risk is the risk that the value of a security may
       decline for reasons relating to the issuer, such as changes in the
       financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

      Interest Rate Risk -- In general, when interest rates go up, prices of
      fixed income securities go down.

      Default Risk -- An issuer of a security may default on its obligation to
      pay principal and/or interest.

      Credit Risk -- An issuer of a security may have its credit rating
      downgraded, which would negatively impact the price of such security.
      Securities with lower credit ratings are generally subject to greater
      fluctuations in value than higher rated securities.

      Call or Prepayment Risk -- An issuer of a security may prepay principal
      earlier than scheduled, which could force the Fund to reinvest in lower
      yielding securities.

      Extension Risk -- Slower than expected principal payments on a
      mortgage-backed or asset-backed security may extend such security's life,
      thereby locking in a below-market interest rate, increasing the security's
      duration and reducing the value of the security.

     - Allocation Risk.  The Sub-Adviser's judgment about the attractiveness and
       risk adjusted return potential of particular asset classes may prove to
       be wrong. By utilizing the balanced approach described herein, the
<PAGE>   140
ING FUNDS TRUST                                                               23
- --------------------------------------------------------------------------------

       Fund's net asset value may not rise as rapidly or as much as the stock
       market during cycles of rising stock prices.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Balanced Fund
has not yet commenced operations, there is no performance information included
in this Prospectus.

 ING EMERGING MARKETS EQUITY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of emerging market issuers. The Fund will
typically maintain investments in at least seven emerging market countries and
will not invest more than 25% of its total assets in any one emerging market
country. The Fund defines an emerging market country as any country the economy
and market of which the World Bank or the United Nations considers to be
emerging or developing or any country determined by the Sub-Advisers to have
emerging economies or developing markets. The Fund considers emerging market
issuers to be companies the securities of which are principally traded in the
capital markets of emerging market countries; that derive at least 50% of their
total revenue or earnings from either goods produced or services rendered in
emerging market countries, regardless of where the securities of such companies
are principally traded; or that are organized under the laws of and have a
principal office in an emerging market country.

     As a general matter, the Fund expects these investments to be in common
stocks of large, mid-sized, and small companies. The Fund may also use options
and futures contracts involving foreign currencies.

     In choosing investments for the Fund, the Sub-Advisers employ a highly
disciplined, four-step investment process that seeks to identify unrecognized
growth potential in stocks of emerging market issuers. The four steps are:

     - First, the Sub-Advisers perform a comprehensive analysis of the relative
       value of geographic regions to determine the degree of representation of
       such geographic regions in the Fund's portfolio;

     - Second, such determinations are reviewed by an independent committee
       within the Sub-Advisers;

     - Third, the Sub-Advisers select investments within the selected
       geographical regions based on comprehensive fundamental analysis; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks of companies located in more developed countries,
       or may not favor equities at all.

- --------------------------------------------------------------------------------

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Emerging Market Risk.  Because the Fund invests primarily in emerging
       markets countries, the risks may be greater, partly because emerging
       market countries may be less politically and economically stable than
       other countries. It may also be more difficult to buy and sell securities
       in emerging market countries.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Emerging
Markets Equity Fund has not yet commenced operations, there is no performance
information included in this Prospectus.

 ING GLOBAL REAL ESTATE FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of companies that are principally
engaged in the real estate industry. In selecting investments for the Fund, the
Sub-Advisers will select companies that derive at least 50% of their total
revenues or earnings from owning, operating, developing and/or managing real
estate. This portion of the portfolio will have investments located in at least
three different countries including the United States. As a general matter, the
Fund expects these investments to be in common stocks and real estate investment
trusts of large, mid-sized, and small companies.

     The Sub-Advisers use a disciplined two-step process for constructing the
Fund's portfolio:

     - First, the Sub-Advisers select sectors and geographic regions in which to
       invest, and determine the degree of representation of such sectors and
       regions, through a systematic evaluation of public and private property
       market trends and conditions.

     - Second, the Sub-Advisers use an in-house valuation process to identify
       investments with superior current income and growth potential relative to
       their peers. This in-house valuation process examines several factors
       including: (i) value and property; (ii) capital structure; and (iii)
       management and strategy.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities. In addition, when interest rates
       increase, the value of income producing equity securities may decrease,
       and when interest rates decrease, the value of income producing equity
       securities may increase.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. Rather, the market could favor
       stocks in
<PAGE>   142
ING FUNDS TRUST                                                               25
- --------------------------------------------------------------------------------

       industries to which the Fund is not exposed, or may not favor equities at
       all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to a particular industry, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives.

     - Real Estate Risk.  Investments in issuers that are principally engaged in
       real estate, including real estate investment trusts ("REITs"), may
       subject the Fund to risks similar to those associated with the direct
       ownership of real estate (in addition to securities market risks). These
       companies are sensitive to factors such as changes in real estate values
       and property taxes, interest rates, cash flow of underlying real estate
       assets, supply and demand, and the management skill and creditworthiness
       of the issuer. REITs may also be affected by tax and regulatory
       requirements.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Global Real
Estate Fund has not yet commenced operations, there is no performance
information included in this Prospectus.

 ING QUALITY OF LIFE FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of U.S. and non-U.S. quality of life
companies. The Fund defines quality of life companies as those companies that
derive at least 50% of their total revenues or earnings from offering products
and services helping persons live longer, healthier and happier lives. Such
companies may include, but will not be limited to, companies engaged in the
research, development, production or distribution of products or services
related to health care (for example, pharmaceutical and consumer goods
companies, biotechnology companies, and health maintenance organization
companies); companies engaged in providing entertainment services or equipment
related to leisure time activities (for example, travel and leisure companies
and sports equipment companies); and companies providing other services or
products desired by the aging baby boomer population (for example, retirement
community development companies). As a general matter, the Fund expects these
investments to be in common stocks of large companies whose market
capitalizations are generally in excess of $10 billion.

     The Sub-Adviser believes that quality of life companies will benefit from
the aging baby boomer generation. The global consumption pattern is steadily
changing as a result of an increase in wealth and a resulting increase in life
expectancy. Especially in the developed countries, the population is rapidly
aging. In the opinion of the Sub-Adviser this development will lend to a
structural increase in healthcare spending. At the same time the growing group
of aging people will have an increasing need for various services and more and
new possibilities of leisure activities. People will be increasingly willing to
invest in their quality of life aiming at longer, healthier and happier lives.

     In choosing investments for the Fund, the Sub-Adviser first identifies
themes which it believes will drive the healthcare, leisure and other industries
benefiting from the aging baby boomer generation. Then, by conducting extensive
fundamental research, the Sub-Adviser analyzes individual companies worldwide to
identify those firms that are most likely to benefit from the selected
investment themes.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An

       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes

- --------------------------------------------------------------------------------

       value of a security may decline for reasons relating to the issuer, such
       as changes in the financial condition of the issuer. Equities generally
       have higher volatility than debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in industries to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to particular industries, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives. Swings in
       investor psychology or significant trading by large institutional
       investors can result in significant price fluctuations and stock price
       declines.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Quality of Life
Fund has not yet commenced operations, there is no performance information
included in this Prospectus.

EXAMPLES

     These Examples are intended to help you compare the cost of investing in
the Funds with the cost of investing in other mutual funds. Each Example assumes
that:

     - you invest $10,000 in Class X shares of each Fund for the time period
       indicated;

     - your investment has a 5% return each year;

     - the Fund's operating expenses remain the same, except for the expiration
       of the contractual expense limitation on October 31, 2000; and

     - you redeem all of your shares at the end of the time period indicated.

     The Examples also reflect your receipt of additional Bonus Shares (see "How
to Purchase Shares" for a discussion of Bonus Shares). Although your actual
costs may be higher or lower, based on these assumptions your costs would be:

     equity team of IIMA and its affiliates. Mr. Kleeven has been employed by
     IIMA and its affiliates since 1997 and has seven years of investment
     experience. Before joining IIMA and its affiliates, Mr. Kleeven was a
     portfolio manager for Robeco Group, Rotterdam, The Netherlands.

                             HOW TO PURCHASE SHARES

     The Funds offer a choice of five share classes, each with its own sales
load and expense structure, allowing you to invest in the way that best suits
your needs. Class X shares are offered in this Prospectus and may be purchased
only by certain qualified investors (including, but not limited to, IRAs, Roth
IRAs, Education IRAs, SEP IRAs, Simple IRAs and 403(b)(7) plans). The Class A,
Class B and Class C shares have different sales charges and other expenses,
which may affect performance. The Class I shares are sold without an initial
sales charge and also are not subject to any Rule 12b-1 fees, shareholder
servicing fees or account servicing fees. The Class I shares may be purchased
only by (i) retirement plans affiliated with ING Group, and (ii) ING Group and
its affiliates for purposes of corporate cash management. Each share class
represents an ownership interest in the same investment portfolio. Any request
for purchases of Class X shares by a non-qualified investor of less than
$1,000,000 will be considered as a purchase request for Class B shares. Any
requests for purchases of Class X shares by a non-qualified investor of
$1,000,000 or more will be considered as a purchase request for Class A shares,
because it is more advantageous for an investor to purchase Class A shares for
such amounts.

     The Funds' shares are distributed by ING Funds Distributor, Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Funds' shares may be
sold by retail broker-dealers that are under common control with the Funds. As
of the date of this Prospectus, such broker-dealers are Compulife Investor
Services, Inc., IFG Network Securities, Inc., Locust Street Securities, Inc.,
Multi-Financial Securities Corporation, VESTAX Securities Corporation, ING
Barings Furman Selz LLC and ING Barings LLC.

     Orders for the purchase of Class X shares of the Funds will be executed at
the net asset value per share next determined after an order has been received.
The public offering price of each Fund is determined as of the close of regular
trading on the New York Stock Exchange (normally 4 p.m. Eastern time) on each
day the Exchange is open for business.

     The public offering price of Class X shares is the net asset value for the
applicable Fund's shares. In addition, you will receive, as a bonus, additional
Class X shares ("Bonus Shares") having a value equal to 2.00% of the amount
invested. The Distributor has undertaken to pay for the Bonus Shares as part of
its services to the Funds. Shares purchased through the reinvestment of
dividends or distributions are not eligible for Bonus Shares.

     If you select Class X shares, you do not pay an initial sales load at the
time of purchase. However, if you redeem your Class X shares within 6 years
after purchase, you may be required to pay a deferred sales load. You will also
pay distribution fees of 0.75% under a distribution plan that the Funds have
adopted under Rule 12b-1 and shareholder servicing fees of 0.25% each year.
Because these fees are paid out of a Fund's assets on an ongoing basis, over
time these fees increase the cost of your investment and may cost you more than
purchasing the Class A shares and paying an initial sales load. The Distributor
uses the money that it receives from the deferred sales loads and the
distribution fees to cover the costs of marketing, advertising, the purchase of
Bonus Shares and compensating the securities dealer who assists you in
purchasing Fund shares. Although Class X shares are sold without an initial
sales load, the Distributor normally pays a sales commission of 2.50% of the
purchase price of Class X shares to the dealer from its own resources at the
time of sale.

     If you redeem Class X shares within 6 years after purchase, you may be
charged a deferred sales load. The

amount of the load gradually decreases as you hold your shares over time,
according to the following schedule:

<TABLE>
<CAPTION>

- -----------------                          -----------

5th year after purchase..................       2%
6th year after purchase..................       1%
Thereafter...............................     NONE
</TABLE>

- ------------------------------

*   The sales load will apply to the lesser of the original cost of the shares
    being redeemed or the proceeds of your redemption. Bonus Shares or shares
    acquired through reinvestment of dividends or distributions are not subject
    to a deferred sales load.

     The deferred sales load relating to Class X shares will be waived in
certain circumstances, such as:

     - Mandated minimum post-retirement withdrawals from an IRA or other
       retirement plan if you are over 59 1/2 years old.

     - Redemptions resulting from shareholder death or disability as long as the
       waiver request is made within one year of death or disability or, if
       later, reasonably promptly following completion of probate.

     - Redemptions resulting from closure by the Fund of the account in which
       shares are held.

     To determine whether the Class X CDSL applies to a redemption, the Fund
redeems shares in the following order: (i) shares acquired by reinvestment of
dividends and capital gains distributions; (ii) shares (including Bonus Shares)
held for over six years; (iii) shares (not including Bonus Shares) in the order
they were purchased (such that shares held the longest are redeemed first); and
(iv) Bonus Shares in the order they were acquired (such that Bonus Shares held
the longest are redeemed first). In the table above, a "year" is a 12 month
period. All purchases are considered to have been made on the business day of
the month in which the purchase was made.

     If you redeem Class X shares and within 90 days buy new shares of the same
class, you will receive a credit for any CDSL paid. If such reinstated shares
are then redeemed within six years of the initial purchase, the CDSL will be
imposed upon the redemption. The amount eligible for this "Reinstatement
Privilege" may not exceed the amount of your redemption proceeds. To exercise
the privilege, contact the Funds at 1-877-INFO-ING

     Your Class X shares convert automatically into Class A shares eight years
after purchase. Any Class X shares received through reinvestment of dividends or
distributions paid on converting shares will also convert at that time. Class A
shares are subject to lower annual expenses than Class X shares. The conversion
of Class X shares to Class A shares is not a taxable event for federal income
tax purposes.

     The minimum initial investment in a Fund is $1,000. Any subsequent
investments must be at least $50. The Distributor may waive these minimums from
time to time. All initial investments should be accompanied by a completed
Account Application. An Account Application accompanies this Prospectus. All
funds received are invested in full and fractional shares of the appropriate
Fund. Certificates for shares are not issued. Contributions to IRAs and
qualified retirement plans are subject to prevailing limits set by the Internal
Revenue Service. Your account will be charged an annual maintenance fee, but you
will not be charged more than one such fee with respect to multiple accounts of
the same plan type established under the same taxpayer identification number.
The Funds reserve the right to reject any purchase order. The Funds will accept
third party checks from qualified financial institutions, such as broker-dealers
and investment advisers that are registered with the Securities and Exchange
Commission, as well as insurance companies, banks, credit unions and thrift
companies. Personal third party checks and non-U.S. checks will not be accepted.
All initial investments may be made using any of the following methods:

                              HOW TO REDEEM SHARES

     You may redeem your shares, in whole or in part, on each day a Fund is
valued. Shares will be redeemed without charge (except any applicable CDSL) at
the net asset value next determined after a redemption request in good order has
been received by the Funds. In the instance where you own more than one class of
shares and the class of shares being redeemed are not subject to the CDSL, those
shares with the highest Rule 12b-1 fee will be redeemed in full prior to any
redemption of shares with a lower Rule 12b-1 fee.

     When purchases are made by check in any Fund, redemption proceeds will be
made available immediately upon clearance of the purchase check, which may take
up to 15 calendar days. You may avoid this delay by investing through wire
transfers of federal funds.

     Once your shares are redeemed, the Funds will ordinarily send the proceeds
by check to you at the address of record on the next business day. To ensure
acceptance of your redemption request, it is important to follow the procedures
described below. If you purchased your shares through an Authorized Broker or
Investment Adviser, please contact them to inquire which redemption methods are
available to you. Under certain circumstances described below, a signature
guarantee may be required. You may redeem your shares using any of the following
methods:

                                  behalf. These organizations may impose certain
                                  restrictions on redemptions and may charge you a fee for
                                  the transaction.

     The Funds reserve the right to redeem in kind. That is, the Funds may honor
redemption requests with readily marketable portfolio securities instead of cash
if during any 90-day period redemptions exceed the lesser of $250,000 or 1% of
the net assets of the redeeming Fund at the beginning of such period. You may
incur transaction costs associated with converting these securities to cash.

     Due to the high costs of maintaining small accounts, the Funds may ask that
you increase your account balance if (1) the value of your account falls below
$500 for three consecutive months as a result of redemptions or exchanges, and
(2) your account has been in existence for at least one year and you have not
made any additional purchases in the account within the preceding six calendar
months. If the account balance remains below the minimum requirement for 60 days
after you are notified, the Funds may close your account and send you the
redemption proceeds.

     Signature Guarantees.  A signature guarantee is designed to protect the
investor, the Funds and their agents by verifying the signature of certain
investors seeking to redeem, transfer, or exchange shares of the Funds.
Signature guarantees are required for:

     - redemptions by mail in excess of $50,000;

     - redemptions by mail if the proceeds are to be paid to someone other than
       the name(s) in which the account is registered;

     - redemptions requesting proceeds to be sent to a new address or an address
       that has been changed within the past 15 days;

     - requests to transfer the registration of shares to another owner; or

     - redemptions or exchanges of shares previously reported as lost/abandoned
       property, whether or not the redemption amount is under $50,000 or the
       proceeds are to be sent to the address of record.

     The foregoing requirements may be waived or modified upon notice to
shareholders.

     Acceptable guarantors include banks, broker-dealers, credit unions,
national securities exchanges, savings associations and any other organization,
provided that such institution or organization qualifies as an "eligible
guarantor institution" as that term is defined in rules adopted by the
Securities and Exchange Commission. For information regarding whether a
particular institution or organization qualifies as an "eligible guarantor
institution," contact the Funds at 1-877-INFO-ING.

                               EXCHANGE PRIVILEGE

     Class X shares of a Fund may be exchanged, based on the per share net asset
values, for Class X shares of any other Fund. You will receive credit for the
period of time you held the shares being exchanged when determining whether the
acquired shares, when redeemed, will be subject to a contingent deferred sales
load.

     Your exchange will be processed at the next determined net asset value
after the Funds receive your request. A new account opened by exchange must be
established with the same name(s), address and social security number as the
existing account.

     You may only exchange shares into a Fund which is authorized for sale in
your state of residence. The Funds may limit each account to eight exchanges per
calendar year. The Funds may change or discontinue the exchange privilege after

                               PRICING OF SHARES

     Each of the Funds prices its shares based on its net asset value. The Funds
value portfolio securities for which market quotations are readily available at
market price. These Funds value 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 Funds may value the security at its fair value as determined
in good faith by or under the supervision of the Board of Trustees. The effect
of using fair value pricing is that a Fund's net asset value will be subject to
the judgment of the Board of Trustees or its designee instead of being
determined by the market. Because some of the Funds may invest in securities
that are primarily listed on foreign exchanges, the value of those Funds' shares
may change on days when you will not be able to purchase or redeem shares.

     Each Fund determines the net asset value of its shares as of the close of
the NYSE (normally 4:00 p.m., Eastern time) on each day the NYSE is open for
business. The price at which a purchase or redemption is effected is based on
the next calculation of a Fund's net asset value after the order is placed.

                          DIVIDENDS AND DISTRIBUTIONS

     Each Fund intends to distribute to its shareholders substantially all of
its investment company taxable income (which includes dividends and interest and
the excess, if any, of net short-term capital gains over net long-term capital
losses). Each of the Funds will declare and pay these dividends annually, except
for the ING Growth & Income Fund, ING Global Real Estate Fund, and the ING
Balanced Fund, which will declare and pay dividends quarterly. In addition, each
Fund intends to distribute, at least annually, substantially all of its net
capital gains (the excess of net long-term capital gains over net short-term
capital losses). In determining amounts of capital gains to be distributed, any

- --------------------------------------------------------------------------------

capital loss carryovers from prior years will be applied against capital gains.

     Dividends and distributions will be reinvested in additional shares of a
Fund at net asset value unless you elect to receive such dividends and
distributions in cash. If you redeem all or a portion of Fund shares prior to a
dividend payment date, you will be entitled on the next dividend payment date to
all dividends declared but unpaid on those shares at the time of their
redemption.

     If you elect to receive distributions in cash and the post office cannot
deliver your checks or if you do not cash your checks within six months, your
dividends may be reinvested in your account at the then-current net asset value
and your account will be converted to the reinvestment option. You will not
receive interest on the amount of your uncashed checks.

     The elections described above may be made either on the Account Application

     Each Fund is treated as a separate entity for federal income tax purposes.
Each Fund intends to qualify as a regulated investment company by satisfying the
requirements under Subchapter M of the Internal Revenue Code of 1986 (the
"Code"), including requirements with respect to diversification of assets,
distribution of income and sources of income. By so qualifying, each Fund
generally will not be subject to federal income tax to the extent that it
distributes investment company taxable income and net realized capital gains in
the manner required under the Code.

     Investment income received by a Fund from sources within foreign countries
may be subject to foreign income taxes withheld at the source. Such withholding
taxes may be reduced or eliminated under the terms of applicable United States
income tax treaties, and the Funds intend to undertake any procedural steps
required to claim the benefits of such treaties.

     Special tax treatment, including a penalty on certain pre-retirement
distributions, is accorded to accounts maintained as qualified retirement plans.
The foregoing discussion is intended for shareholders that are exempt from
federal income taxes. You should consult your own tax advisor as to the federal,
state and local tax consequences of ownership of shares of the Funds in your
particular circumstances.

                  MORE INFORMATION ABOUT STRATEGIES AND RISKS

     A Fund's risk profile is largely a factor of the principal securities in
which it invests and investment techniques that it uses. The following pages
discuss the risks associated with certain of the types of securities in which
the Funds may invest and certain of the investment practices that the Funds may
use. For more information about these and other types of securities and
investment techniques used by the Funds, see the Statement of Additional
Information. Unless indicated otherwise, the following descriptions apply to all
Funds.

     Many of the investment techniques and strategies discussed in this
Prospectus and in the Statement of Additional Information are discretionary,
which means that the Investment Manager or Sub-Adviser can decide whether to use
them or not. The Investment Manager or Sub-Adviser may also use investment
techniques or make investments in securities that are not a part of the Fund's
principal investment strategy.

     Temporary Defensive Strategies (All Funds).  When the Investment Manager or
Sub-Adviser to a Fund anticipates unusual market or other conditions, the Fund
may temporarily depart from its principal investment strategies. Under such
circumstances, up to 100% of the Fund's assets may be invested in investment
grade fixed income securities (for example, rated at least BBB by Standard &
Poor's Rating Group or Baa by Moody's Investor Services), money market
securities, certificates of deposit, bankers' acceptances, commercial paper or
in any other securities which in either the Investment Manager's or
Sub-Adviser's opinion are more conservative than the types of securities in
which the Fund typically invests. To the extent a Fund is engaged in temporary
defensive investments, it will not be pursuing its investment objective.

     Investments in Foreign Securities (All Funds).  There are certain risks in
owning foreign securities, including those resulting from: fluctuations in
currency exchange rates; devaluation of currencies; political or economic
developments and the possible imposition of currency exchange blockages or other
foreign governmental laws or restrictions; reduced availability of public
information concerning issuers; accounting, auditing and financial reporting
standards or other regulatory practices and requirements that are not uniform
when compared to those applicable to domestic companies; settlement and
clearance procedures in some countries that may not be reliable and can result
in delays in settlement; higher transaction and custody expenses than for
domestic securities; and limitations on foreign ownership of equity securities.
Also, securities of many foreign companies may be less liquid and the prices
more volatile than those of domestic companies. With certain foreign countries,
there is the possibility of expropriation, nationalization, confiscatory
taxation and limitations on the use or removal of funds or other assets of the
Funds, including the withholding of dividends.

     Each Fund that invests in foreign securities may enter into foreign
currency transactions either on a spot or cash basis at prevailing rates or
through forward foreign currency exchange contracts in order to have the
necessary currencies to settle transactions or to help protect the Fund against
<PAGE>   156
ING FUNDS TRUST                                                               39
- --------------------------------------------------------------------------------

adverse changes in foreign currency exchange rates. Such efforts could limit
potential gains that might result from a relative increase in the value of such
currencies, and might, in certain cases, result in losses to the Fund.

     Emerging Market Investments (ING International Equity Fund and ING Emerging
Markets Equity Fund).  Because of less developed markets and economies and, in
some countries, less mature governments and governmental institutions, the risks
of investing in foreign securities can be intensified in the case of investments
in issuers domiciled or doing substantial business in emerging market countries.
These risks include: high concentration of market capitalization and trading
volume in a small number of issuers representing a limited number of industries,
as well as a high concentration of investors and financial intermediaries;
political and social uncertainties; over-dependence on exports, especially with
respect to primary commodities, making these economies vulnerable to changes in
commodity prices; overburdened infrastructure and obsolete financial systems;
environmental problems; less well developed legal systems; and less reliable
custodial services and settlement practices.

     Corporate and Municipal Debt Securities (All Funds). Corporate debt
securities are subject to the risk of the issuer's inability to meet principal
and interest payments on the obligation and may also be subject to price
volatility due to such factors as interest rate sensitivity, market perception
of the credit-worthiness of the issuer and general market liquidity. When
interest rates decline, the value of the debt securities can be expected to
rise, and when interest rates rise, the value of those securities can be
expected to decline. Debt securities with longer maturities tend to be more
sensitive to interest rate movements than those with shorter maturities.

     Initial Public Offerings (All Funds).  A significant portion of a Fund's
return may be attributable to its investment in initial public offerings. When a
Fund's asset base is small, the impact of such investments on a Fund's return
will be magnified. As the Fund's assets grow, it is probable that the effect of
the Fund's investment in initial public offerings on the Fund's total return
will decline.

     U.S. Government Securities (All Funds).  Some U.S. Government agency
securities may be subject to varying degrees of credit risk, and all U.S.
Government securities may be subject to price declines in the securities due to
changing interest rates.

     Convertible Securities (All Funds).  The price of a convertible security
will normally fluctuate in some proportion to changes in the price of the
underlying equity security, and as such is subject to risks relating to the
activities of the issuer and general market and economic conditions. The income
component of convertible securities causes fluctuations based upon changes in
interest rates and the credit quality of the issuer. Convertible securities are
often lower rated securities. A Fund may be required to redeem or convert a
convertible security before the holder would otherwise choose.

     Other Investment Companies (All Funds).  Each Fund may invest up to 10% of
its assets in other unaffiliated investment companies. There is no limit with
regard to investments in affiliated investment companies. When a Fund invests in
other investment companies, you indirectly pay a proportionate share of the
expenses of that other investment company (including management fees,
administration fees, and custodial fees) in addition to the expenses of the
Fund.

     Restricted and Illiquid Securities (All Funds).  Each Fund may invest up to
15% of its net assets in restricted and illiquid securities. If a security is
illiquid, the Fund might be unable to sell the security at a time when the
sub-adviser might wish to sell, and the security could have the effect of
decreasing the overall level of the Fund's liquidity. Further, the lack of an
established secondary market may make it more difficult to value illiquid
securities, which could vary from the amount the Fund could realize upon
disposition. Restricted securities, i.e., securities subject to legal or
contractual restrictions on resale, may be illiquid. However, some restricted
securities may be treated as liquid, although they may be less liquid than
registered securities traded on established secondary markets.

     Mortgage-Related Securities (All Funds).  Although mortgage loans
underlying a mortgage-backed security may have maturities of up to 30 years, the
actual average life of a mortgage-backed security typically will be
substantially less because the mortgages will be subject to normal principal
amortization, and may be prepaid prior to maturity. Like other fixed income
securities, when interest rates rise, the value of a mortgage-backed security
generally will decline; however, when interest rates are declining, the value of
mortgage-backed securities with prepayment features may not increase as much as
other fixed income securities. The rate of prepayments on underlying mortgages
will affect the price and volatility of a mortgage-related security, and may
have the effect of shortening or extending the effective maturity of the
security beyond what was anticipated at the time of the purchase. Unanticipated
rates of prepayment on underlying mortgages can be expected to increase the
volatility of such securities. In addition, the value of these securities may
fluctuate in response to the market's perception of the creditworthiness of the
issuers of mortgage-related securities owned by a Fund. Additionally, although
mortgages and mortgage-related securities are generally supported by some form
of government or private guarantee and/or insurance, there is no assurance that
private guarantors or insurers will be able to meet their obligations.

     Asset-Backed Securities (All Funds).  Asset-backed securities involve
certain risks that are not posed by mortgage-related securities, resulting
mainly from the fact that asset-backed securities often do not contain the
benefit of a complete security interest in the related collateral. The
<PAGE>   157
 40                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

risks associated with asset-backed securities may be reduced by the addition of
credit enhancements such as a bank letter of credit or a third-party guarantee.

     Derivatives (All Funds).  Generally, derivatives can be characterized as
financial instruments whose performance is derived, at least in part, from the
performance of an underlying asset or assets. Some derivatives are sophisticated
instruments that typically involve a small investment of cash relative to the
magnitude of risks assumed. These may include swap agreements, options, forwards
and futures. Derivative securities are subject to market risk, which could be
significant for those that have a leveraging effect. Many of the Funds do not
invest in these types of derivatives, so please check the description of the
Fund's policies found in the Statement of Additional Information. Derivatives
are also subject to credit risks related to the counterparty's ability to
perform, and any deterioration in the counterparty's creditworthiness could
adversely affect the instrument. A risk of using derivatives is that the adviser
might imperfectly judge the market's direction. For instance, if a derivative is
used as a hedge to offset investment risk in another security, the hedge might
not correlate to the market's movements and may have unexpected or undesired
results, such as a loss or a reduction in gains.

     Dollar Roll Transactions (All Funds).  The Funds may enter into dollar roll
transactions wherein the Fund sells fixed income securities, typically
mortgage-backed securities, and makes a commitment to purchase similar, but not
identical, securities at a later date from the same party. Like a forward
commitment, during the roll period no payment is made for the securities
purchased and no interest or principal payments on the security accrue to the
purchaser, but a Fund assumes the risk of ownership. A Fund is compensated for
entering into dollar roll transactions by the difference between the current
sales price and the forward price for the future purchase, as well as by the
interest earned on the cash proceeds of the initial sale. Like other when-issued
securities or firm commitment agreements, dollar roll transactions involve the
risk that the market value of the securities sold by the Funds may decline below
the price at which a Fund is committed to purchase similar securities. In the
event the buyer of securities under a dollar roll transaction becomes insolvent,
the Funds' use of the proceeds of the transaction may be restricted pending a
determination by the other party, or its trustee or receiver, whether to enforce
the Funds' obligation to repurchase the securities.

     Repurchase Agreements (All Funds).  Each Fund may enter into repurchase
agreements, which involve the purchase by a Fund of a security that the seller
has agreed to buy back. If the seller defaults and the collateral value
declines, the Fund might incur a loss. If the seller declares bankruptcy, the
Fund may not be able to sell the collateral at the desired time.

     Lending Portfolio Securities (All Funds).  In order to generate additional
income, each Fund may lend portfolio securities in an amount up to 33 1/3% of
its total assets to broker-dealers, major banks, or other recognized domestic
institutional borrowers of securities. As with other extensions of credit, there
are risks of delay in recovery or even loss of rights in the collateral should
the borrower default or fail financially.

     Borrowing (All Funds).  Each Fund may borrow for certain types of temporary
or emergency purposes subject to certain limits. Borrowing may exaggerate the
effect of any increase or decrease in the value of portfolio securities or the
net asset value of a Fund, and money borrowed will be subject to interest costs.
Interest costs on borrowings may fluctuate with changing market rates of
interest and may partially offset or exceed the return earned on borrowed funds.
Under adverse market conditions, a Fund might have to sell portfolio securities
to meet interest or principal payments at a time when fundamental investment
considerations would not favor such sales.

     Reverse Repurchase Agreements (All Funds).  A reverse repurchase agreement
involves the sale of a security, with an agreement to repurchase the same
securities at an agreed upon price and date. Whether such a transaction produces
a gain for a Fund depends upon the costs of the agreements and the income and
gains of the securities purchased with the proceeds received from the sale of
the security. If the income and gains on the securities purchased fail to exceed
the costs, net asset value will decline faster than otherwise would be the case.
Reverse repurchase agreements, as leveraging techniques, may increase a Fund's
yield; however, such transactions may result in a shareholder's loss of
principal.

     Short Sales (ING International Equity Fund and ING Emerging Markets Equity
Fund).  A "short sale" is the sale by a Fund of a security which has been
borrowed from a third party on the expectation that the market price will drop.
If the price of the security rises, the Fund may have to cover its short
position at a higher price than the short sale price, resulting in a loss.

     Investments in Small- and Mid-Capitalization Companies (All Funds).  The
Funds may invest in small and mid capitalization companies. Investments in mid-
and small-capitalization companies involve greater risk than is customarily
associated with larger, more established companies due to the greater business
risks of small size, limited markets and financial resources, narrow product
lines and the frequent lack of depth of management. The securities of smaller
companies are often traded over-the-counter and may not be traded in volumes
typical on a national securities exchange. Consequently, the securities of
smaller companies may have limited market stability and may be subject to more
abrupt or erratic market movements than securities of larger, more established
growth companies or the market averages in general.

- --------------------------------------------------------------------------------

     Non-diversified Investment Companies (ING Global Brand Names Funds, ING
Focus Fund, ING Global Real Estate Fund, ING Internet Fund, ING Internet Fund II
and ING Quality of Life Fund).  Certain Funds are classified as non-diversified
investment companies under the 1940 Act, which means that each Fund is not
limited by the 1940 Act in the proportion of its assets that it may invest in
the obligations of a single issuer. The investment of a large percentage of a
Fund's assets in the securities of a small number of issuers may cause that
Fund's share price to fluctuate more than that of a diversified investment
company.

     Concentration (ING Global Information Technology Fund, ING Global
Communications Fund, ING Internet Fund, ING Internet Fund II, ING Global Real
Estate Fund and ING Quality of Life Fund).  Certain Funds "concentrate" (for
purposes of the 1940 Act) their assets in securities related to a particular
sector or industry, which means that at least 25% of its assets will be invested
in these assets at all times. As a result, each Fund may be subject to greater
market fluctuation than a fund which has securities representing a broader range
of investment alternatives.

     Fundamental and Non-Fundamental Policies (All Funds).  Unless otherwise
stated, all investment objectives and policies are non-fundamental and may be
amended without shareholder approval.

     Percentage Investment Limitations (All Funds).  Unless otherwise stated,
percentage limitations in this prospectus apply at the time of investment.

     Portfolio Turnover (All Funds).  Each Fund may engage in frequent and
active trading of portfolio securities to achieve its investment objective. A
high portfolio turnover rate involves greater expenses to a Fund, including
brokerage commissions and other transaction costs, and is likely to generate
more taxable short-term gains for shareholders, which may have an adverse effect
on the performance of the Fund.

                              FINANCIAL HIGHLIGHTS

     The financial highlights table is intended to help you understand the
financial performance of the Funds' Class X Shares for the fiscal period ended
October 31, 1999. Certain information reflects financial results for a single
Fund share. The total returns in the table represent the rate than an investor
would have earned or lost on an investment in the Funds (assuming reinvestment
of all dividends and distributions). Past performance does not guarantee future
results. This information has been audited by Ernst & Young LLP, independent
auditors, whose report, along with the Funds' financial statements, is included
in the Statement of Additional Information, which is available upon request.
Because the following Funds had not commenced operations prior to October 31,
1999, financial highlights are not presented for ING Tax Efficient Equity Value
Fund, ING Global Communications Fund, ING Internet Fund II, ING Balanced Fund,
ING Emerging Markets Equity Fund, ING Global Real Estate Fund and ING Quality of
Life Fund.

                               FUNDS AT A GLANCE

 ING INTERMEDIATE BOND FUND

     Investment Objective.  A high level of current income consistent with the
preservation of capital and liquidity.

     Main Investments.  A diversified portfolio of debt securities, with a
minimum average portfolio quality being investment grade, as discussed herein,
and a dollar-weighted average maturity generally ranging between three and ten
years.

     Main Risks.  You could lose money. Other risks include price volatility and
risks, as discussed herein, related to investments in fixed income securities,
including sensitivity to interest rate fluctuations. Investor demand, changes in
the financial condition of issuers of securities, and general economic
conditions, among other factors, may affect the market value and yield of the
Fund's securities.

 ING HIGH YIELD BOND FUND

     Investment Objective.  A high level of current income and total return.

     Main Investments.  A diversified portfolio of high yield (high risk) debt
securities that are unrated or rated below investment grade, as discussed
herein.

     Main Risks.  You could lose money. Other risks include price volatility and
risks, as discussed herein, related to investments in fixed income securities,
including sensitivity to interest rate fluctuations. Lower-rated securities may
be subject to wider fluctuations in yield and market value than higher-rated
securities. The market for high yield securities may be less liquid than the
markets for higher-rated securities, which may have an adverse effect on the
market value of certain securities.

 ING INTERNATIONAL BOND FUND

     Investment Objective.  High total return.

     Main Investments.  A non-diversified portfolio of investment grade debt
securities of issuers located throughout the world, not including the United
States.

     Main Risks.  You could lose money. Other risks include price volatility and
risks, as discussed herein, related to investments in fixed income securities,
including sensitivity to interest rate fluctuations, and maintaining a
non-diversified portfolio. The Fund also will experience risks related to
investments in foreign securities (for example, currency exchange rate
fluctuations).

 ING MORTGAGE INCOME FUND

     Investment Objective.  Long-term income consistent with the preservation of
capital.

     Main Investments.  A diversified portfolio of mortgage-backed securities
rated at least "A" or the equivalent.

     Main Risks.  You could lose money. Other risks include price volatility and
risks, as discussed herein, related to investments in fixed income securities,
including sensitivity to interest rate fluctuations. The Fund's mortgage-backed
securities also will be subject to prepayment risk, which is the risk that the
principal on the underlying mortgage loans may be prepaid at any time, and
extension risk, which is the risk that an unexpected rise in interest rates will
extend the life of a mortgage-backed security beyond the expected prepayment
time.

- --------------------------------------------------------------------------------

                                   BOND FUNDS

 ING INTERMEDIATE BOND FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income consistent with the preservation of capital and
liquidity.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of debt securities which, at the time of investment, are rated
investment grade (for example, rated at least BBB by Standard & Poor's Rating
Group or Baa by Moody's Investor Services) or have an equivalent rating by a
nationally recognized statistical rating organization, or of comparable quality
if unrated. Although the Fund may invest a portion of its assets in high yield
(high risk) debt securities rated below investment grade, the Fund will seek to
maintain a minimum average portfolio quality rating of at least investment
grade. The dollar-weighted average maturity of the Fund will generally range
between three and ten years.

     The Fund may invest the remainder of its assets in: convertible securities
and preferred stocks; U.S. Government securities, securities of foreign
governments and supranational organizations, and high-quality money market
instruments that the Sub-Adviser believes are appropriate in light of the Fund's
investment objective; municipal bonds, notes and commercial paper; and debt
securities of foreign issuers. The Fund may purchase structured debt obligations
and may engage in dollar roll transactions and swap agreements. The Fund may
also sell securities short and may use options and futures contracts involving
securities, securities indices and interest rates. A portion of the Fund's
assets may be invested in mortgage-backed securities and asset-backed debt
securities.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, five step investment process which uses fundamental economic and
market research to identify bond market sectors and individual securities
expected to provide above-average returns. The five steps are:

     - First, the Sub-Adviser examines the sensitivity to interest rate
       movements of the portfolio and of the specific holdings of the portfolio
       to position the Fund in a way that attempts to maximize return while
       minimizing volatility.

     - Second, the Sub-Adviser reviews yields relative to maturity and risk of
       bonds to determine the risk/reward characteristics of bonds of different
       maturity classes.

     - Third, the Sub-Adviser identifies sectors that offer attractive value
       relative to other sectors.

     - Fourth, the Sub-Adviser selects securities within identified sectors that
       offer attractive value relative to other securities within their sectors.

     - Finally, the Sub-Adviser seeks trading opportunities to take advantage of
       market inefficiencies to purchase bonds at prices below their calculated
       value.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

      Interest Rate Risk -- In general, when interest rates go up, prices of
      fixed income securities go down. Securities with longer maturities are
      subject to greater fluctuations in value than securities with shorter
      maturities.

      Spread Risk -- The price of a fixed income security is generally
      determined by adding an interest rate spread to a benchmark interest rate,
      such as the U.S. Treasury rate. As the spread on a security widens (or
      increases), the price (or value) of the security falls.

      Default Risk -- An issuer of a security may default on its obligation to
      pay principal and/or interest.

      Credit Risk -- An issuer of a security may have its credit rating
      downgraded, which would negatively impact the price of such security.
      Securities with lower credit ratings are generally subject to greater
      fluctuations in value than higher rated securities.

      Call or Prepayment Risk -- An issuer of a security may prepay principal
      earlier than scheduled, which could force the Fund to reinvest in lower
      yielding securities.

      Extension Risk -- Slower than expected principal payments on a
      mortgage-backed or asset-backed security may extend such security's life,
      thereby

ING FUNDS TRUST                                                                3
- --------------------------------------------------------------------------------

       locking in a below-market interest rate, increasing the security's
       duration and reducing the value of the security.

     - Risk of High Yield Bonds.  High yield bonds carry particular market risks
       and may experience greater volatility in market value than investment
       grade bonds. Changes in interest rates, the market's perception of the
       issuers and the creditworthiness of the issuers may significantly affect
       the value of these bonds. Some of these securities may have a structure
       that makes their reaction to interest rates and other factors difficult
       to predict, causing their value to be highly volatile. Certain high yield
       bonds, such as zero coupon, deferred interest and payment-in-kind bonds,
       are issued at deep discounts and may experience greater volatility in
       market value. The secondary market for high yield bonds may be less
       liquid than the markets for higher quality securities and this may have
       an adverse effect on the market values of certain securities.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security, as well as credit risk with
       respect to the counterparty to the derivative instrument. The use of
       derivatives may reduce returns.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class X shares would have
substantially similar annual returns because the Class X shares are invested in
the same portfolio of securities and the annual returns would differ only to the
extent that Class X shares and Class A shares do not have the same expenses. For
purposes of the Average Annual Returns table, Class A shares' return reflects a
deduction of an initial sales load.

ANNUAL TOTAL RETURNS

     The following bar chart depicts changes in the performance of the Fund's
Class A shares for the year ended December 31, 1999. The bar chart does not
reflect sales loads. If it did, the annual total returns shown would be lower.

 ING HIGH YIELD BOND FUND

     Investment Objective.  The Fund seeks to provide investors with a high

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of high yield (high risk) bonds. High yield bonds are debt
securities that are not rated by a nationally recognized statistical rating
organization or are rated below investment grade (for example, rated below BBB
by Standard & Poor's Rating Group or Baa by Moody's Investor Services) or have
an equivalent rating by a nationally recognized statistical rating organization.
The Fund defines high yield bonds to include bank loans, payment-in-kind
securities, fixed, variable, floating rate and deferred interest debt
obligations, zero coupon bonds, mortgage-backed and asset-backed debt
obligations, structured debt obligations and convertible bonds, provided they
are unrated or rated below investment grade. In evaluating the quality of a
particular high yield bond for investment by the Fund, the Sub-Adviser does not
rely exclusively on ratings assigned by the nationally recognized statistical
rating organizations. The Sub-Adviser will utilize a security's credit rating as
simply one indication of an issuer's creditworthiness and will principally rely
upon its own analysis of any security. However, the Sub-Adviser does not have
restrictions on the rating level of the securities in the Fund's portfolio and
may purchase and hold securities in default. There are no restrictions on the
average maturity of the Fund or the maturity of any single investment.
Maturities may very widely depending on the Sub-Adviser's assessment of interest
rate trends and other economic or market factors.

     Any remaining assets may be invested in investment grade debt securities;
common and preferred stocks; U.S. Government securities and money market
instruments that the Sub-Adviser believes are appropriate in light of the Fund's
investment objectives; and debt securities of foreign issuers. The Fund may
purchase structured debt obligations and may engage in dollar roll transactions
and swap agreements. The Fund may also use options and futures contracts
involving securities, securities indices and interest rates.

     The Fund will not purchase any common stocks if, after such purchase, more
than 20% of the value of its total assets would be invested in common stocks.
The Fund will invest in common stocks in order to attempt to achieve either a
combination of its primary and secondary objectives, in which case the common
stocks will be dividend-paying, or to achieve its secondary objective, in which
case the common stocks may not pay dividends.

     In choosing investments for the Fund, the Sub-Adviser combines extensive
company and industry research with relative value analysis to identify high
yield bonds expected to provide above-average returns. Relative value analysis
is intended to enhance returns by moving from overvalued to undervalued sectors
of the bond market. The Sub-Adviser's team approach to decision making includes
contributions from individual managers responsible for specific industry
sectors.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

       Interest Rate Risk -- In general, when interest rates go up, prices of
       fixed income securities go down. Securities with longer maturities are
       subject to greater fluctuations in value than securities with shorter
       maturities.

       Spread Risk -- The price of a fixed income security is generally
       determined by adding an interest rate spread to a benchmark interest
       rate, such as the U.S. Treasury rate. As the spread on a security widens
       (or increases), the price (or value) of the security falls.

       Default Risk -- An issuer of a security may default on its obligation to
       pay principal and/or interest.

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk -- An issuer of a security may prepay principal
       earlier than scheduled, which could force the Fund to reinvest in lower
       yielding securities.

       Extension Risk -- Slower than expected principal payments on a
       mortgage-backed or asset-backed security may extend such security's life,
       thereby locking in a below-market interest rate, increasing the
       security's duration and reducing the value of the security.

     - Risk of High Yield Bonds.  High yield bonds carry particular market risks
       and may experience greater
<PAGE>   168
ING FUNDS TRUST                                                                5
- --------------------------------------------------------------------------------

       volatility in market value than investment grade bonds. Changes in
       interest rates, the market's perception of the issuers and the
       creditworthiness of the issuers may significantly affect the value of
       these bonds. Some of these securities may have a structure that makes
       their reaction to interest rates and other factors difficult to predict,
       causing their value to be highly volatile. Certain high yield bonds, such
       as zero coupon, deferred interest and payment-in-kind bonds, may be
       issued at deep discounts and may experience greater volatility in market
       value. The secondary market for high yield bonds may be less liquid than
       the markets for higher quality securities and this may have an adverse
       effect on the market values of certain securities.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security, as well as credit risk with
       respect to the counterparty to the derivative instrument. The use of
       derivatives may reduce returns.

     - Risks of Equity Investments.  Equity securities face market, issuer and
       other risks, and their values may go down, sometimes rapidly and
       unpredictably. Market risk is the risk that securities may decline in
       value due to factors affecting securities markets generally or particular
       industries. Issuer risk is the risk that the value of a security may
       decline for reasons relating to the issuer, such as changes in the
       financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class X shares would have
substantially similar annual returns because the Class X shares are invested in
the same portfolio of securities and the annual returns would differ only to the
extent that Class X shares and Class A shares do not have the same expenses. For
purposes of the Average Annual Returns table, Class A shares' return reflects a
deduction of an initial sales load.

 ING INTERNATIONAL BOND FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of fixed income securities of international issuers which,
at the time of investment, are rated investment grade (for example, rated at
least BBB by Standard & Poor's Rating Group or Baa by Moody's Investor Services)
or have an equivalent rating by a nationally recognized statistical rating
organization, or of comparable quality if unrated. This portion of the portfolio
will have investments in at least three different countries outside of the
United States. There are no restrictions on the average maturity of the Fund or
the maturity of any single investment. Maturities may vary widely depending on
the Sub-Advisers' assessment of interest rate trends and other economic or
market factors. Fixed income securities eligible for purchase by the Fund
consist of:

     - securities issued or guaranteed by foreign governments, their political
       subdivisions, agencies or instrumentalities;

     - corporate bonds and debentures rated investment grade (for example, rated
       at least BBB by Standard & Poor's Rating Group or Baa by Moody's Investor
       Services);

     - obligations of supranational entities;

     - repurchase agreements involving the foregoing securities;

     - loan participations;

     - short-term commercial paper of U.S. or foreign issuers rated in the
       highest two rating categories by a nationally recognized statistical
       rating organization; and

     - swap agreements.

     Any remaining assets of the Fund may be invested in securities denominated
in U.S. dollars or foreign currencies which are rated below investment grade
(for example, rated below BBB by Standard & Poor's Rating Group or Baa by
Moody's Investor Services) or have an equivalent rating by a nationally
recognized statistical rating organization, or of comparable quality if unrated;
U.S. Government securities; obligations of commercial banks, savings and loan
institutions, and U.S. and foreign branches of foreign banks that have total
assets of $500 million or more as shown on the last published financial
statements at the time of investment; mortgage-backed and asset-backed
securities rated within the three highest rating categories by a nationally
recognized statistical rating organization; receipts; and guaranteed investment
contracts. The Fund may also use options and futures contracts involving
securities, securities indices, interest rates and foreign currencies.

     In choosing investments for the Fund, the Sub-Advisers employ a highly
disciplined, four step investment process that seeks to identify bond market
sectors expected to provide high and sustainable real rates of return. The four
steps are:

     - First, the Sub-Adviser performs a comprehensive analysis of the relative
       value of bond issuances between countries and of currencies to determine
       the degree of representation of such countries and currencies in the
       Fund's portfolio;

     - Second, country allocations, as well as currency and maturity weightings,
       are reviewed by an independent committee within the Sub-Adviser;

     - Third, the Sub-Adviser selects investments within the selected countries
       and currencies based on comprehensive fundamental analysis; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities and currencies.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

      Interest Rate Risk -- In general, when interest rates go up, prices of
      fixed income securities go down. Securities with longer maturities are
      subject to greater fluctuations in value than securities with shorter
      maturities.

      Spread Risk -- The price of a fixed income security is generally
      determined by adding an interest rate spread to a benchmark interest rate,
      such as the U.S. Treasury rate. As the spread on a security widens (or
      increases), the price (or value) of the security falls.

      Default Risk -- An issuer of a security may default on its obligation to
      pay principal and/or interest.
<PAGE>   170
ING FUNDS TRUST                                                                7
- --------------------------------------------------------------------------------

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk -- An issuer of a security may prepay principal
       earlier than scheduled, which could force the Fund to reinvest in lower
       yielding securities.

       Extension Risk -- Slower than expected principal payments on a
       mortgage-backed or asset-backed security may extend such security's life,
       thereby locking in a below-market interest rate, increasing the
       security's duration and reducing the value of the security.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class X shares would have
substantially similar annual returns because the Class X shares are invested in
the same portfolio of securities and the annual returns would differ only to the
extent that Class X shares and Class A shares do not have the same expenses. For
purposes of the Average Annual Returns table, Class A shares' return reflects a
deduction of an initial sales load.

 ING MORTGAGE INCOME FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
income consistent with the preservation of capital.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in mortgage-backed securities. Mortgage-backed securities are securities that
directly or indirectly represent a participation in, or are secured by and
payable from, mortgage loans secured by real property. There are currently three
basic types of mortgage-backed securities: (i) those issued or guaranteed by the
U.S. Government or one of its agencies or instrumentalities, such as Government
National Mortgage Association ("GNMA"), Federal National Mortgage Association
("FNMA") and Federal Home Loan Mortgage Corporation ("FHLMC"); (ii) those issued
by private issuers that represent an interest in or are collateralized by
mortgage-backed securities issued or guaranteed by the U.S. Government or one of
its agencies or instrumentalities; and (iii) those issued by private issuers
that represent an interest in or are collateralized by whole mortgage loans or
mortgage-backed securities without a government guarantee but usually having
some form of private credit enhancement. The Fund may invest in adjustable rate
and fixed rate mortgage securities. The Fund's investments will be rated, at the
time of investment, "A" or better by a nationally recognized statistical rating
organization, or of comparable quality if unrated.

     Any remaining assets of the Fund may be invested in other types of fixed
income securities, including, but not limited to, U.S. Government securities,
corporate bonds, notes and debentures, asset-backed securities and money market
instruments that the Sub-Adviser believes are appropriate in light of the Fund's
investment objective. The Fund may also use options and futures contracts
involving securities, securities indices and interest rates.

     There are no restrictions on the average maturity of the Fund or on the
maturity of any single instrument. Accordingly, the Fund may vary the proportion
of its holdings in long- and short-term debt securities in order to reflect its
assessment of prospective changes in interest rates even if such action may
adversely affect current income. For example, if in the opinion of the
Sub-Adviser, interest rates generally are expected to decline, the Fund may sell
its shorter term securities and purchase longer term securities in order to
benefit from greater expected relative price appreciation; however, the
securities sold may have a higher current yield than those being purchased. The
success of this strategy will depend on the Sub-Adviser's ability to forecast
changes in interest rates. Moreover, the Fund intends to manage its portfolio
actively by taking advantage of trading opportunities such as sales of portfolio
securities and purchases of higher yielding securities of similar quality due to
distortions in normal yield differentials.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

       respect to the counterparty to the derivative instrument. The use of
       derivatives may reduce returns.

(1) Other expenses are based on estimated amounts for the current fiscal year.
(2) The Investment Manager has entered into expense limitation contracts with
    each of the Funds, under which it will limit expenses of each Fund,
    excluding interest, taxes, brokerage and extraordinary expenses through
    October 31, 2000. The expense limit for each such Fund is shown as "Net
    Expenses". Fee waiver and/or reimbursements by the Investment Manager may
    vary in order to achieve such contractually obligated "Net Expenses".

EXAMPLES

     These Examples are intended to help you compare the cost of investing in
the Funds with the cost of investing in other mutual funds. Each Example assumes
that:

     - you invest $10,000 in Class X shares of each Fund for the time period
       indicated;

     - your investment has a 5% return each year;

     - the Fund's operating expenses remain the same, except for the expiration
       of the contractual expense limitations on October 31, 2000; and

     - you redeem all of your shares at the end of the time period indicated.

     The Examples also reflect your receipt of additional Bonus Shares (see "How
to Purchase Shares" for a discussion of Bonus Shares). Although your actual
costs may be higher or lower, based on these assumptions your costs would be:

                             HOW TO PURCHASE SHARES

     The Funds offer a choice of five share classes, each with its own sales
load and expense structure, allowing you to invest in the way that best suits
your needs. Class X shares are offered in this Prospectus and may be purchased
only by certain qualified investors (including, but not limited to, IRAs, Roth
IRAs, Education IRAs, SEP IRAs, Simple IRAs and 403(b)(7) plans). The Class A,
Class B and Class C shares have different sales charges and other expenses,
which may affect performance. The Class I shares are sold without an initial
sales charge and also are not subject to any Rule 12b-1 fees, shareholder
servicing fees or account servicing fees. The Class I shares may be purchased
only by (i) retirement plans affiliated with ING Group, and (ii) ING Group and
its affiliates for purposes of corporate cash management. Each share class
represents an ownership interest in the same investment portfolio. Any request
for purchases of Class X shares by a non-qualified investor of less than
$1,000,000 will be considered as a purchase request for Class B shares. Any
requests for purchases of Class X shares by a non-qualified investor of
$1,000,000 or more will be considered as a purchase request for Class A shares,
because it is more advantageous for an investor to purchase Class A shares for
such amounts.

     The Funds' shares are distributed by ING Funds Distributor, Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Funds' shares may be
sold by retail broker-dealers that are under common control with the Funds. As
of the date of this Prospectus, such broker-dealers are Compulife Investor
Services, Inc., IFG Network Securities, Inc., Locust Street Securities, Inc.,
Multi-Financial Securities Corporation, VESTAX Securities Corporation, ING
Barings Furman Selz LLC and ING Barings LLC.

     Orders for the purchase of Class X shares of the Funds will be executed at
the net asset value per share next determined after an order has been received.
The public offering price of each Fund is determined as of the close of regular
trading on the New York Stock Exchange (normally 4 p.m. Eastern time) on each
day the Exchange is open for business.

     The public offering price of Class X shares is the net asset value for the
applicable Fund's shares. In addition, you will receive, as a bonus, additional
Class X shares ("Bonus Shares") having a value equal to 2.00% of the amount
invested. The Distributor has undertaken to pay for the Bonus Shares as part of
its services to the Funds. Shares purchased through the reinvestment of
dividends or distributions are not eligible for Bonus Shares.

     If you select Class X shares, you do not pay an initial sales load at the
time of purchase. However, if you redeem your Class X shares within 6 years
after purchase, you may be required to pay a deferred sales load. You will also
pay distribution fees of 0.75% under a distribution plan that the Funds have
adopted under Rule 12b-1 and shareholder servicing fees of 0.25% each year.
Because these fees are paid out of a Fund's assets on an ongoing basis, over
time these fees increase the cost of your investment and may cost you more than
purchasing the Class A shares and paying an initial sales load. The Distributor
uses the money that it receives from the deferred sales loads and the
distribution fees to cover the costs of marketing, advertising, the purchase of
Bonus Shares and compensating the securities dealer who assists you in
purchasing Fund shares. Although Class X shares are sold without an initial
sales load, the Distributor normally pays a sales commission of 2.50% of the
purchase price of Class X shares to the dealer from its own resources at the
time of sale.

     If you redeem Class X shares within 6 years after purchase, you may be
charged a deferred sales load. The amount of the load gradually decreases as you
hold your shares over time, according to the following schedule:

<TABLE>
<CAPTION>
REDEMPTION DURING                          SALES LOAD*
- -----------------                          -----------
<S>                                        <C>

5th year after purchase..................       2%
6th year after purchase..................       1%
Thereafter...............................     NONE
</TABLE>

- ------------------------------

*   The sales load will apply to the lesser of the original cost of the shares
    being redeemed or the proceeds of your redemption. Bonus Shares or shares
    acquired through reinvestment of dividends or distributions are not subject
    to a deferred sales load.

     The deferred sales load relating to Class X shares will be waived in
certain circumstances, such as:

     - Mandated minimum post-retirement withdrawals from an IRA or other
       retirement plan if you are over 59 1/2 years old.

     - Redemptions resulting from shareholder death or disability as long as the
       waiver request is made within one year of death or disability or, if
       later, reasonably promptly following completion of probate.

     - Redemptions resulting from closure by the Fund of the account in which
       shares are held.
<PAGE>   175
 12                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

     To determine whether the Class X CDSL applies to a redemption, the Fund
redeems shares in the following order: (i) shares acquired by reinvestment of
dividends and capital gains distributions; (ii) shares (including Bonus Shares)
held for over six years; (iii) shares (not including Bonus Shares) in the order
they were purchased (such that shares held the longest are redeemed first); and
(iv) Bonus Shares in the order they were acquired (such that Bonus Shares held
the longest are redeemed first). In the table above, a "year" is a 12 month
period. All purchases are considered to have been made on the business day of
the month in which the purchase was made.

     If you redeem Class X shares and within 90 days buy new shares of the same
class, you will receive a credit for any CDSL paid. If such reinstated shares
are then redeemed within six years of the initial purchase, the CDSL will be
imposed upon the redemption. The amount eligible for this "Reinstatement
Privilege" may not exceed the amount of your redemption proceeds. To exercise
the privilege, contact the Funds at 1-877-INFO-ING.

     Your Class X shares convert automatically into Class A shares eight years
after purchase. Any Class X shares received through reinvestment of dividends or
distributions paid on converting shares will also convert at that time. Class A
shares are subject to lower annual expenses than Class X shares. The conversion
of Class X shares to Class A shares is not a taxable event for federal income
tax purposes.

     The minimum initial investment in a Fund is $1,000. Any subsequent
investments must be at least $50. The Distributor may waive these minimums from
time to time. All initial investments should be accompanied by a completed
Account Application. An Account Application accompanies this Prospectus. All
funds received are invested in full and fractional shares of the appropriate
Fund. Certificates for shares are not issued. Contributions to IRAs and
qualified retirement plans are subject to prevailing limits set by the Internal
Revenue Service. Your account will be charged an annual maintenance fee, but you
will not be charged more than one such fee with respect to multiple accounts of
the same plan type established under the same taxpayer identification number.
The Funds reserve the right to reject any purchase order. The Funds will accept
third party checks from qualified financial institutions, such as broker-dealers
and investment advisers that are registered with the Securities and Exchange
Commission, as well as insurance companies, banks, credit unions and thrift
companies. Personal third party checks and non-U.S. checks will not be accepted.
All initial investments may be made using any of the following methods:

                              HOW TO REDEEM SHARES

     You may redeem your shares, in whole or in part, on each day a Fund is
valued. Shares will be redeemed without charge (except any applicable CDSL) at
the net asset value next determined after a redemption request in good order has
been received by the Funds. In the instance where you own more than one class of
shares and the class of shares being redeemed are not subject to the CDSL, those
shares with the highest Rule 12b-1 fee will be redeemed in full prior to any
redemption of shares with a lower Rule 12b-1 fee.

     When purchases are made by check in any Fund, redemption proceeds will be
made available immediately upon clearance of the purchase check, which may take
up to 15 calendar days. You may avoid this delay by investing through wire
transfers of federal funds.

     Once your shares are redeemed, the Funds will ordinarily send the proceeds
by check to you at the address of record on the next business day. To ensure
acceptance of your redemption request, it is important to follow the procedures
described below. If you purchased your shares through an Authorized Broker or
Investment Adviser, please contact them to inquire which redemption methods are
available to you. Under certain circumstances described below, a signature
guarantee may be required. You may redeem your shares using any of the following
methods:

  Through an Authorized Broker    You may redeem your shares by contacting your authorized
  or Investment Adviser           broker or investment advisor and instructing him or her
                                  to redeem your shares. Your representative will then
                                  contact the Funds and place a redemption trade on your
                                  behalf. These organizations may impose certain
                                  restrictions on redemptions and may charge you a fee for
                                  the transaction.
</TABLE>

     The Funds reserve the right to redeem in kind. That is, the Funds may honor
redemption requests with readily marketable portfolio securities instead of cash
if during any 90-day period redemptions exceed the lesser of $250,000 or 1% of
the net assets of the redeeming Fund at the beginning of such period. You may
incur transaction costs associated with converting these securities to cash.

     Due to the high costs of maintaining small accounts, the Funds may ask that
you increase your account balance if (1) the value of your account falls below
$500 for three consecutive months as a result of redemptions or exchanges, and
(2) your account has been in existence for at least one year and you have not
made any additional purchases in the account within the preceding six calendar
months. If the account balance remains below the minimum requirement for 60 days
after you are notified, the Funds may close your account and send you the
redemption proceeds.

     Signature Guarantees.  A signature guarantee is designed to protect the
investor, the Funds and their agents by verifying the signature of certain
investors seeking to

- --------------------------------------------------------------------------------

redeem, transfer, or exchange shares of the Funds. Signature guarantees are
required for:

     - redemptions by mail in excess of $50,000;

     - redemptions by mail if the proceeds are to be paid to someone other than
       the name(s) in which the account is registered;

     - redemptions requesting proceeds to be sent to a new address or an address
       that has been changed within the past 15 days;

     - requests to transfer the registration of shares to another owner; or

     - redemptions or exchanges of shares previously reported as lost/abandoned
       property, whether or not the redemption amount is under $50,000 or the
       proceeds are to be sent to the address of record.

     The foregoing requirements may be waived or modified upon notice to
shareholders.

     Acceptable guarantors include banks, broker-dealers, credit unions,
national securities exchanges, savings associations and any other organization,
provided that such institution or organization qualifies as an "eligible
guarantor institution" as that term is defined in rules adopted by the
Securities and Exchange Commission. For information regarding whether a
particular institution or organization qualifies as an "eligible guarantor
institution," contact the Funds at 1-877-INFO-ING.

                               EXCHANGE PRIVILEGE

     Class X shares of a Fund may be exchanged, based on the per share net asset
values, for Class X shares of any other Fund. You will receive credit for the
period of time you held the shares being exchanged when determining whether the
acquired shares, when redeemed, will be subject to a contingent deferred sales
load.

     Your exchange will be processed at the next determined net asset value
after the Funds receive your request. A new account opened by exchange must be
established with the same name(s), address and social security number as the
existing account.

     You may only exchange shares into a Fund which is authorized for sale in
your state of residence. The Funds may limit each account to eight exchanges per
calendar year. The Funds may change or discontinue the exchange privilege after
giving you 60 days' prior notice. An exchange of shares is a taxable event on
which you may realize a gain or loss. You may exchange shares using any of the
following methods:

</TABLE>

                               PRICING OF SHARES

     Each of the Funds prices its shares based on its net asset value. The Funds
value portfolio securities for which market quotations are readily available at
market price. These Funds value 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 Funds may value the security at its fair value as determined
in good faith by or under the supervision of the Board of Trustees. The effect
of using fair value pricing is that a Fund's net asset value will be subject to
the judgment of the Board of Trustees or its designee instead of being
determined by the market. Because some of the Funds may invest in securities
that are primarily listed on foreign exchanges, the value of those Funds' shares
may change on days when you will not be able to purchase or redeem shares.

     Each Fund determines the net asset value of its shares as of the close of
the NYSE (normally 4:00 p.m., Eastern time) on each day the NYSE is open for
business. The price at which a purchase or redemption is effected is based on
the next calculation of a Fund's net asset value after the order is placed.

                          DIVIDENDS AND DISTRIBUTIONS

     Each Fund intends to distribute to its shareholders substantially all of
its investment company taxable income (which includes dividends and interest and
the excess, if any, of net short-term capital gains over net long-term capital
losses). Each of the Funds will declare dividends daily and pay dividends
monthly. In addition, each Fund intends to distribute, at least annually,
substantially all of its net capital gains (the excess of net long-term capital
gains over net short-term capital losses). In determining amounts of capital
gains to be distributed, any capital loss carryovers from prior years will be
applied against capital gains.

     Dividends and distributions will be reinvested in additional shares of a
Fund at net asset value unless you elect to receive such dividends and
distributions in cash. If you redeem all or a portion of Fund shares prior to a
dividend payment date, you will be entitled on the next dividend payment date to
all dividends declared but unpaid on those shares at the time of their
redemption.

     If you elect to receive distributions in cash and the post office cannot
deliver your checks or if you do not cash your checks within six months, your
dividends may be reinvested in your account at the then-current net asset value
and your account will be converted to the reinvestment option. You will not
receive interest on the amount of your uncashed checks.

     The elections described above may be made either on the Account Application
or by calling the Fund at 1-877-INFO-ING.

                                     TAXES

     Each Fund is treated as a separate entity for federal income tax purposes.
Each Fund intends to qualify as a regulated investment company by satisfying the
requirements under Subchapter M of the Internal Revenue Code of 1986 (the
"Code"), including requirements with respect to diversification of assets,
distribution of income and sources of income. By so qualifying, each Fund
generally will not be subject to federal income tax to the extent that it
distributes investment company taxable income and net realized capital gains in
the manner required under the Code.

     Investment income received by a Fund from sources within foreign countries
may be subject to foreign income taxes withheld at the source. Such withholding
taxes may be reduced or eliminated under the terms of applicable United
<PAGE>   179

- --------------------------------------------------------------------------------

States income tax treaties, and the Funds intend to undertake any procedural
steps required to claim the benefits of such treaties.

     Special tax treatment, including a penalty on certain pre-retirement
distributions, is accorded to accounts maintained as qualified retirement plans.
The foregoing discussion is intended for shareholders that are exempt from
federal income taxes. You should consult your own tax advisor as to the federal,
state and local tax consequences of ownership of shares of the Funds in your
particular circumstances.

                  MORE INFORMATION ABOUT STRATEGIES AND RISKS

     A Fund's risk profile is largely a factor of the principal securities in
which it invests and investment techniques that it uses. The following pages
discuss the risks associated with certain of the types of securities in which
the Funds may invest and certain of the investment practices that the Funds may
use. For more information about these and other types of securities and
investment techniques used by the Funds, see the Statement of Additional
Information. Unless indicated otherwise, the following descriptions apply to all
Funds.

     Many of the investment techniques and strategies discussed in this
Prospectus and in the Statement of Additional Information are discretionary,
which means that the Investment Manager or Sub-Adviser can decide whether to use
them or not. The Investment Manager or Sub-Adviser may also use investment
techniques or make investments in securities that are not a part of the Fund's
principal investment strategy.

     Temporary Defensive Strategies (All Funds).  When the Investment Manager
or Sub-Adviser to a Fund anticipates unusual market or other conditions, the
Fund may temporarily depart from its principal investment strategies. Under
such circumstances, up to 100% of the Fund's assets may be invested in
investment grade fixed income securities (for example, rated at least BBB by
Standard & Poor's Rating Group or Baa by Moody's Investor Services), money
market securities, certificates of deposit, bankers' acceptances, commercial
paper or in any other securities which in either the Investment Manager's or
Sub-Adviser's opinion are more conservative than the types of securities in
which the Fund typically invests. To the extent a Fund is engaged in temporary
defensive investments, it will not be pursuing its investment objective.

     Investments in Foreign Securities (All Funds except ING Mortgage Income
Fund).  There are certain risks in owning foreign securities, including those
resulting from: fluctuations in currency exchange rates; devaluation of
currencies; political or economic developments and the possible imposition of
currency exchange blockages or other foreign governmental laws or restrictions;
reduced availability of public information concerning issuers; accounting,
auditing and financial reporting standards or other regulatory practices and
requirements that are not uniform when compared to those applicable to domestic
companies; settlement and clearance procedures in some countries that may not be
reliable and can result in delays in settlement; higher transaction and custody
expenses than for domestic securities; and limitations on foreign ownership of
equity securities. Also, securities of many foreign companies may be less liquid
and the prices more volatile than those of domestic companies. With certain
foreign countries, there is the possibility of expropriation, nationalization,
confiscatory taxation and limitations on the use or removal of funds or other
assets of the Funds, including the withholding of dividends.

     Each Fund that invests in foreign securities may enter into foreign
currency transactions either on a spot or cash basis at prevailing rates or
through forward foreign currency exchange contracts in order to have the
necessary currencies to settle transactions or to help protect the Fund against
adverse changes in foreign currency exchange rates. Such efforts could limit
potential gains that might result from a relative increase in the value of such
currencies, and might, in certain cases, result in losses to the Fund.

     Emerging Market Investments (ING High Yield Bond Fund, ING Intermediate
Bond Fund and ING International Bond Fund).  Because of less developed markets
and economies and, in some countries, less mature governments and governmental
institutions, the risks of investing in foreign securities can be intensified in
the case of investments in issuers domiciled or doing substantial business in
emerging market countries. These risks include: high concentration of market
capitalization and trading volume in a small number of issuers representing a
limited number of industries, as well as a high concentration of investors and
financial intermediaries; political and social uncertainties; over-dependence on
exports, especially with respect to primary commodities, making these economies
vulnerable to changes in commodity prices; overburdened infrastructure and
obsolete financial systems; environmental problems; less well developed legal
systems; and less reliable custodial services and settlement practices.

     High Yield Securities (ING High Yield Bond Fund, ING Intermediate Bond Fund
and ING International Bond Fund). Investments in high yield securities generally
provide greater income and increased opportunity for capital appreciation than
investments in higher quality debt securities, but they
<PAGE>   180
ING FUNDS TRUST                                                               17
- --------------------------------------------------------------------------------

also typically entail greater potential price volatility and principal and
income risk. High yield securities are not considered investment grade, and are
regarded as predominantly speculative with respect to the issuing company's
continuing ability to meet principal and interest payments. The prices of high
yield securities have been found to be less sensitive to interest rate changes
than higher-rated investments, but more sensitive to adverse economic downturns
or individual corporate developments. High yield securities structured as
zero-coupon or payment-in-kind securities tend to be more volatile. The
secondary market in which high yield securities are traded is generally less
liquid than the market for higher-grade bonds. At times of less liquidity, it
may be more difficult to value high yield securities.

     Corporate and Municipal Debt Securities (All Funds). Corporate debt
securities are subject to the risk of the issuer's inability to meet principal
and interest payments on the obligation and may also be subject to price
volatility due to such factors as interest rate sensitivity, market perception
of the credit-worthiness of the issuer and general market liquidity. When
interest rates decline, the value of the debt securities can be expected to
rise, and when interest rates rise, the value of those securities can be
expected to decline. Debt securities with longer maturities tend to be more
sensitive to interest rate movements than those with shorter maturities.

     Initial Public Offerings (All Funds).  A significant portion of a Fund's
return may be attributable to its investment in initial public offerings. When a
Fund's asset base is small, the impact of such investments on a Fund's return
will be magnified. As the Fund's assets grow, it is probable that the effect of
the Fund's investment in initial public offerings on the Fund's total return
will decline.

     U.S. Government Securities (All Funds).  Some U.S. Government agency
securities may be subject to varying degrees of credit risk, and all U.S.
Government securities may be subject to price declines in the securities due to
changing interest rates.

     Convertible Securities (All Funds).  The price of a convertible security
will normally fluctuate in some proportion to changes in the price of the
underlying equity security, and as such is subject to risks relating to the
activities of the issuer and general market and economic conditions. The income
component of convertible securities causes fluctuations based upon changes in
interest rates and the credit quality of the issuer. Convertible securities are
often lower rated securities. A Fund may be required to redeem or convert a
convertible security before the holder would otherwise choose.

     Other Investment Companies (All Funds).  Each Fund may invest up to 10% of
its assets in other unaffiliated investment companies. There is no limit with
regard to investments in affiliated investment companies. When a Fund invests in
other investment companies, you indirectly pay a proportionate share of the
expenses of that other investment company (including management fees,
administration fees, and custodial fees) in addition to the expenses of the
Fund.

     Restricted and Illiquid Securities (All Funds).  Each Fund may invest up to
15% of its net assets in restricted and illiquid securities. If a security is
illiquid, the Fund might be unable to sell the security at a time when the
sub-adviser might wish to sell, and the security could have the effect of
decreasing the overall level of the Fund's liquidity. Further, the lack of an
established secondary market may make it more difficult to value illiquid
securities, which could vary from the amount the Fund could realize upon
disposition. Restricted securities, i.e., securities subject to legal or
contractual restrictions on resale, may be illiquid. However, some restricted
securities may be treated as liquid, although they may be less liquid than
registered securities traded on established secondary markets.

     Mortgage-Related Securities (All Funds).  Although mortgage loans
underlying a mortgage-backed security may have maturities of up to 30 years, the
actual average life of a mortgage-backed security typically will be
substantially less because the mortgages will be subject to normal principal
amortization, and may be prepaid prior to maturity. Like other fixed income
securities, when interest rates rise, the value of a mortgage-backed security
generally will decline; however, when interest rates are declining, the value of
mortgage-backed securities with prepayment features may not increase as much as
other fixed income securities. The rate of prepayments on underlying mortgages
will affect the price and volatility of a mortgage-related security, and may
have the effect of shortening or extending the effective maturity of the
security beyond what was anticipated at the time of the purchase. Unanticipated
rates of prepayment on underlying mortgages can be expected to increase the
volatility of such securities. In addition, the value of these securities may
fluctuate in response to the market's perception of the creditworthiness of the
issuers of mortgage-related securities owned by a Fund. Additionally, although
mortgages and mortgage-related securities are generally supported by some form
of government or private guarantee and/or insurance, there is no assurance that
private guarantors or insurers will be able to meet their obligations.

     Asset-Backed Securities (All Funds).  Asset-backed securities involve
certain risks that are not posed by mortgage-related securities, resulting
mainly from the fact that asset-backed securities often do not contain the
benefit of a complete security interest in the related collateral. The risks
associated with asset-backed securities may be reduced by the addition of credit
enhancements such as a bank letter of credit or a third-party guarantee.

     Derivatives (All Funds).  Generally, derivatives can be characterized as
financial instruments whose performance is
<PAGE>   181
 18                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

derived, at least in part, from the performance of an underlying asset or
assets. Some derivatives are sophisticated instruments that typically involve a
small investment of cash relative to the magnitude of risks assumed. These may
include swap agreements, options, forwards and futures. Derivative securities
are subject to market risk, which could be significant for those that have a
leveraging effect. Many of the Funds do not invest in these types of
derivatives, so please check the description of the Fund's policies found in the
Statement of Additional Information. Derivatives are also subject to credit
risks related to the counterparty's ability to perform, and any deterioration in
the counterparty's creditworthiness could adversely affect the instrument. A
risk of using derivatives is that the adviser might imperfectly judge the
market's direction. For instance, if a derivative is used as a hedge to offset
investment risk in another security, the hedge might not correlate to the
market's movements and may have unexpected or undesired results, such as a loss
or a reduction in gains.

     Dollar Roll Transactions (All Funds).  The Funds may enter into dollar roll
transactions wherein the Fund sells fixed income securities, typically
mortgage-backed securities, and makes a commitment to purchase similar, but not
identical, securities at a later date from the same party. Like a forward
commitment, during the roll period no payment is made for the securities
purchased and no interest or principal payments on the security accrue to the
purchaser, but a Fund assumes the risk of ownership. A Fund is compensated for
entering into dollar roll transactions by the difference between the current
sales price and the forward price for the future purchase, as well as by the
interest earned on the cash proceeds of the initial sale. Like other when-issued
securities or firm commitment agreements, dollar roll transactions involve the
risk that the market value of the securities sold by the Funds may decline below
the price at which a Fund is committed to purchase similar securities. In the
event the buyer of securities under a dollar roll transaction becomes insolvent,
the Funds' use of the proceeds of the transaction may be restricted pending a
determination by the other party, or its trustee or receiver, whether to enforce
the Funds' obligation to repurchase the securities.

     Repurchase Agreements (All Funds).  Each Fund may enter into repurchase
agreements, which involve the purchase by a Fund of a security that the seller
has agreed to buy back. If the seller defaults and the collateral value
declines, the Fund might incur a loss. If the seller declares bankruptcy, the
Fund may not be able to sell the collateral at the desired time.

     Lending Portfolio Securities (All Funds).  In order to generate additional
income, each Fund may lend portfolio securities in an amount up to 33 1/3% of
its total assets to broker-dealers, major banks, or other recognized domestic
institutional borrowers of securities. As with other extensions of credit, there
are risks of delay in recovery or even loss of rights in the collateral should
the borrower default or fail financially.

     Borrowing (All Funds).  Each Fund may borrow for certain types of temporary
or emergency purposes subject to certain limits. Borrowing may exaggerate the
effect of any increase or decrease in the value of portfolio securities or the
net asset value of a Fund, and money borrowed will be subject to interest costs.
Interest costs on borrowings may fluctuate with changing market rates of
interest and may partially offset or exceed the return earned on borrowed funds.
Under adverse market conditions, a Fund might have to sell portfolio securities
to meet interest or principal payments at a time when fundamental investment
considerations would not favor such sales.

     Reverse Repurchase Agreements (All Funds).  A reverse repurchase agreement
involves the sale of a security, with an agreement to repurchase the same
securities at an agreed upon price and date. Whether such a transaction produces
a gain for a Fund depends upon the costs of the agreements and the income and
gains of the securities purchased with the proceeds received from the sale of
the security. If the income and gains on the securities purchased fail to exceed
the costs, net asset value will decline faster than otherwise would be the case.
Reverse repurchase agreements, as leveraging techniques, may increase a Fund's
yield; however, such transactions may result in a shareholder's loss of
principal.

     Short Sales (ING Intermediate Bond Fund and ING High Yield Bond Fund).  A
"short sale" is the sale by a Fund of a security which has been borrowed from a
third party on the expectation that the market price will drop. If the price of
the security rises, the Fund may have to cover its short position at a higher
price than the short sale price, resulting in a loss.

     Investments in Small- and Mid-Capitalization Companies (ING High Yield Bond
Fund and ING Intermediate Bond Fund).  Certain Funds may invest in small and mid
capitalization companies. Investments in mid-and small-capitalization companies
involve greater risk than is customarily associated with larger, more
established companies due to the greater business risks of small size, limited
markets and financial resources, narrow product lines and the frequent lack of
depth of management. The securities of smaller companies are often traded
over-the-counter and may not be traded in volumes typical on a national
securities exchange. Consequently, the securities of smaller companies may have
limited market stability and may be subject to more abrupt or erratic market
movements than securities of larger, more established growth companies or the
market averages in general.

     Non-diversified Investment Companies (ING International Bond
Fund).  Certain Funds are classified as non-diversified investment companies
under the 1940 Act, which means that each Fund is not limited by the 1940 Act

- --------------------------------------------------------------------------------

in the proportion of its assets that it may invest in the obligations of a
single issuer. The investment of a large percentage of a Fund's assets in the
securities of a small number of issuers may cause that Fund's share price to
fluctuate more than that of a diversified investment company.

     Fundamental and Non-Fundamental Policies (All Funds).  Unless otherwise
stated, all investment objectives and policies are non-fundamental and may be
amended without shareholder approval.

     Percentage Investment Limitations (All Funds).  Unless otherwise stated,
percentage limitations in this prospectus apply at the time of investment.

     Portfolio Turnover (All Funds).  Each Fund may engage in frequent and
active trading of portfolio securities to achieve its investment objective. A
high portfolio turnover rate involves greater expenses to a Fund, including
brokerage commissions and other transaction costs, and is likely to generate
more taxable short-term gains for shareholders, which may have an adverse effect
on the performance of the Fund.

                              FINANCIAL HIGHLIGHTS

     The financial highlights table is intended to help you understand the
financial performance of the Funds' Class X Shares for the fiscal period ended
October 31, 1999. Certain information reflects financial results for a single
Fund share. The total returns in the table represent the rate than an investor
would have earned or lost on an investment in the Funds (assuming reinvestment
of all dividends and distributions). Past performance does not guarantee future
results. This information has been audited by Ernst & Young LLP, independent
auditors, whose report, along with the Funds' financial statements, is included
in the Statement of Additional Information, which is available upon request.
Because the following Fund had not commenced operations prior to October 31,
1999, financial highlights are not presented for ING Mortgage Income Fund.

- --------------------------------------------------------------------------------

                               MONEY MARKET FUNDS

 ING MONEY MARKET FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income as is consistent with the preservation of capital and
liquidity and the maintenance of a stable $1.00 net asset value per share.

     Principal Investment Strategies.  The Fund will operate as a diversified
fund and invest in a portfolio of high-quality, U.S. dollar denominated
short-term debt obligations which are determined by the Sub-Adviser to present
minimal credit risks.

     Portfolio investments of the Fund are valued based on the amortized cost
valuation method pursuant to Rule 2a-7 under the Investment Company Act of 1940.
Obligations in which the Fund invests generally have remaining maturities of 397
days or less, although upon satisfying certain conditions of Rule 2a-7, the Fund
may, to the extent otherwise permissible, invest in instruments subject to
repurchase agreements and certain variable and floating rate obligations that
bear longer final maturities. The dollar-weighted average portfolio maturity of
the Fund will not exceed 90 days.

     The Fund will invest in obligations permitted to be purchased under Rule
2a-7 including, but not limited to, (i) U.S. Government securities and
obligations of its agencies or instrumentalities; (ii) commercial paper,
mortgage-backed and asset-backed securities, guaranteed investment contracts,
loan participation interests, medium-term notes, and other promissory notes,
including floating and variable rate obligations; and (iii) the following
domestic, Yankeedollar and Eurodollar obligations: certificates of deposit, time
deposits, bankers acceptances, commercial paper, and other promissory notes,
including floating and variable rate obligations issued by U.S. or foreign bank
holding companies and their bank subsidiaries, branches and agencies. The Fund
may invest more than 25% of its total assets in instruments issued by domestic
banks.

     The Fund may purchase securities on a "when-issued" basis and purchase or
sell them on a "forward commitment" basis. The Fund may also invest in variable
rate master demand obligations, which are unsecured demand notes that permit the
underlying indebtedness to vary, and provide for periodic adjustments in the
interest rate. The Fund may enter into repurchase agreements.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, four step investment process designed to ensure preservation of
capital and liquidity, as well as adherence to regulatory requirements. The four
steps are:

     - First, a formal list of high-quality issuers is actively maintained;

     - Second, securities of issuers on the approved list which meet maturity
       guidelines and are rated "first tier" (that is, they are given the
       highest short-term rating by at least two nationally recognized
       statistical rating organizations, or by a single rating organization if a
       security is rated only by that organization, or are determined to be of
       comparable quality by the Sub-Adviser pursuant to guidelines approved by
       the Fund's Board of Trustees) are selected for investment;

     - Third, diversification is continuously monitored to ensure that
       regulatory limits are not exceeded; and

     - Finally, portfolio maturity decisions are made based upon expected cash
       flows, income opportunities available in the market and expectations of
       future interest rates.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  An investment in the Fund is not a bank deposit and is
not insured or guaranteed by the Federal Deposit Insurance Corporation or any
other government agency. Although the Fund seeks to preserve the value of your
investment at $1.00 per share, it is possible to lose money by investing in the
Fund. The Fund's yield will vary and the Fund may not achieve as high a level of
current income as other funds that do not limit their investments to the
high-quality securities in which the Fund invests.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class X shares would have
substantially similar annual returns because the Class X shares are invested in
the same portfolio of securities and the annual returns would differ only to the
extent that Class X shares and Class A shares do not have the same expenses.

     The Fund's seven-day yield as of December 31, 1999 for the Class X shares
was 4.42%. The "seven-day yield" is an annualized figure -- the amount you would
earn if you kept your investment in the Fund and the Fund continued to earn the
same net interest income throughout the year.

     The Fund's seven-day effective yield as of December 31, 1999 for the Class
X shares was 4.51%. The "seven-day effective yield" (also an annualized figure)
assumes that dividends are reinvested and compounded.

 ING U.S. TREASURY MONEY MARKET FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income as is consistent with liquidity, maximum safety of
principal and the maintenance of a stable $1.00 net asset value per share.

     Principal Investment Strategies.  The Fund will operate as a diversified
fund and invest in direct short-term obligations of the United States Treasury,
which are backed by the full faith and credit of the United States Government.
The Fund may also invest in repurchase agreements which are fully collateralized
by U.S. Treasury securities. The Fund may purchase U.S. Treasury securities on a
"when-issued" basis and purchase or sell them on a "forward commitment" basis.

     Portfolio investments of the Fund are valued based on the amortized cost
valuation method pursuant to Rule 2a-7 under the Investment Company Act of 1940.
Obligations in which the Fund invests generally have remaining maturities of 397
days or less, although upon satisfying certain conditions of Rule 2a-7, the Fund
may, to the extent otherwise permissible, invest in instruments subject to
repurchase agreements and certain variable and floating rate obligations that
bear longer final maturities. The dollar-weighted average portfolio maturity of
the Fund will not exceed 90 days.

     Maturity decisions are made by the Sub-Adviser based upon liquidity
requirements, yield curve analysis and market expectations of future interest
rates.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  An investment in the Fund is not a bank deposit and is
not insured or guaranteed by the Federal Deposit Insurance Corporation or any
other government agency. Although the Fund seeks to preserve the value of your
investment at $1.00 per share, it is possible to lose money by investing in the
Fund. The Fund's yield will vary and the Fund may not achieve as high a level of
current income as other funds that do not limit their investments to the
high-quality securities in which the Fund invests.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING U.S. Treasury
Money Market Fund has not yet commenced operations, there is no performance
information included in this Prospectus.

(1) Other expenses for the ING U.S. Treasury Money Market Fund are based on
    estimated amounts for the current fiscal year.

(2) The Investment Manager has entered into expense limitation contracts with
    each of the Funds, under which it will limit expenses of each Fund,
    excluding interest, taxes, brokerage and extraordinary expenses through
    October 31, 2000. The expense limit for each such Fund is shown as "Net
    Expenses". Fee waiver and/or reimbursements by the Investment Manager may
    vary in order to achieve such contractually obligated "Net Expenses".

EXAMPLES

     These Examples are intended to help you compare the cost of investing in
the Funds with the cost of investing in other mutual funds. Each Example assumes
that:

     - you invest $10,000 in Class X shares of each Fund for the time period
       indicated;

     - your investment has a 5% return each year;

     - the Fund's operating expenses remain the same, except for the expiration
       of its contractual expense limitations on October 31, 2000; and

     - you redeem all of your shares at the end of the time period indicated.

     The Examples also reflect your receipt of additional Bonus Shares (see "How
to Purchase Shares" for a discussion of Bonus Shares). Although your actual
costs may be higher or lower, based on these assumptions your costs would be:

                            MANAGEMENT OF THE FUNDS

     The Investment Manager.  ING Mutual Funds Management Co. LLC (the
"Investment Manager") serves as each Fund's investment manager. The Investment
Manager is a wholly owned indirect subsidiary of ING Groep N.V. ("ING Group")
and is registered with the Securities and Exchange Commission. The Investment
Manager is located at 1475 Dunwoody Drive, West Chester, PA 19380. As of
December 31, 1999, the Investment Manager managed over $1.23 billion in assets.

     The Investment Manager supervises all aspects of each Fund's operations and
provides investment advisory services to the Funds. This includes engaging
sub-advisers, as well as monitoring and evaluating the management of the assets
of each such Fund by its sub-adviser. The Investment Manager has acted as an
investment adviser to mutual funds since 1998. Today, the Investment Manager
advises or manages 30 investment portfolios, including the Funds, encompassing a
broad range of investment objectives.

     Investment Manager Compensation.  The following table shows the aggregate

also advises other registered investment companies.

     ING Money Market Fund.  Ms. Jennifer J. Thompson, CFA leads a team of three
     investment professionals in managing the Fund. Ms. Thompson has been
     employed by IIM as an investment professional since 1998 and has seven

                             HOW TO PURCHASE SHARES

     The Funds offer a choice of five share classes, each with its own sales
load and expense structure, allowing you to invest in the way that best suits
your needs. Class X shares are offered in this Prospectus and may be purchased
only by certain qualified investors (including, but not limited to, IRAs, Roth
IRAs, Education IRAs, SEP IRAs, Simple IRAs and 403(b)(7) plans). The Class A,
Class B and Class C shares have different sales charges and other expenses,
which may affect performance. The Class I shares are sold without an initial
sales charge and also are not subject to any Rule 12b-1 fees, shareholder
servicing fees or account servicing fees. The Class I shares may be purchased
only by (i) retirement plans affiliated with ING Group, and (ii) ING Group and
its affiliates for purposes of corporate cash management. Each share class
represents an ownership interest in the same investment portfolio. Any request
for purchases of Class X shares by a non-qualified investor of less than
$1,000,000 will be considered as a purchase request for Class B shares. Any
requests for purchases of Class X shares by a non-qualified investor of
$1,000,000 or more will be considered as a purchase request for Class A shares,
because it is more advantageous for an investor to purchase Class A shares for
such amounts.

- --------------------------------------------------------------------------------

     The Funds' shares are distributed by ING Funds Distributor, Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Funds' shares may be
sold by retail broker-dealers that are under common control with the Funds. As
of the date of this Prospectus, such broker-dealers are Compulife Investor
Services, Inc., IFG Network Securities, Inc., Locust Street Securities, Inc.,
Multi-Financial Securities Corporation, VESTAX Securities Corporation, ING
Barings Furman Selz LLC and ING Barings LLC.

     Orders for the purchase of Class X shares of the Funds will be executed at
the net asset value per share next determined after an order has been received.
The public offering price of each Fund is determined as of the close of regular
trading on the New York Stock Exchange (normally 4 p.m. Eastern time) on each
day the Exchange and the Federal Reserve Bank are open for business.

     Notwithstanding the foregoing, a purchase order for shares of a Fund within
this Prospectus must generally be received by a specified "cut-off" time to be
executed on the same day at the price per share next determined, provided that
the Funds' custodian receives federal funds or other immediately available funds
by 4 p.m. Eastern time. The cut-off time applicable to the ING Money Market Fund
is 3:00 p.m. Eastern time and the cut-off time applicable to the ING U.S.
Treasury Money Market Fund is 12 noon Eastern time.

     The public offering price of Class X shares is the net asset value for the
applicable Fund's shares. In addition, you will receive, as a bonus, additional
Class X shares ("Bonus Shares") having a value equal to 2.00% of the amount
invested. The Distributor has undertaken to pay for the Bonus Shares as part of
its services to the Funds. Shares purchased through the reinvestment of
dividends or distributions are not eligible for Bonus Shares.

     If you select Class X shares, you do not pay an initial sales load at the
time of purchase. However, if you redeem your Class X shares within 6 years
after purchase, you may be required to pay a deferred sales load. You will also
pay distribution fees of 0.75% under a distribution plan that the Funds have
adopted under Rule 12b-1 and shareholder servicing fees of 0.25% each year.
Because these fees are paid out of a Fund's assets on an ongoing basis, over
time these fees increase the cost of your investment and may cost you more than
purchasing Class A shares. The Distributor uses the money that it receives from
the deferred sales loads and the distribution fees to cover the costs of
marketing, advertising, the purchase of Bonus Shares and compensating the
securities dealer who assists you in purchasing Fund shares. Although Class X
shares are sold without an initial sales load, the Distributor normally pays a
sales commission of 2.50% of the purchase price of Class X shares to the dealer
from its own resources at the time of sale.

     If you redeem Class X shares within 6 years after purchase, you may be
charged a deferred sales load. The amount of the load gradually decreases as you
hold your shares over time, according to the following schedule:

<TABLE>
<CAPTION>
REDEMPTION DURING                          SALES LOAD*
- -----------------                          -----------
<S>                                        <C>
1st year after purchase..................       5%
2nd year after purchase..................       4%
3rd year after purchase..................       4%
4th year after purchase..................       3%
5th year after purchase..................       2%
6th year after purchase..................       1%
Thereafter...............................     NONE
</TABLE>

- ------------------------------

*   The sales load will apply to the lesser of the original cost of the shares
    being redeemed or the proceeds of your redemption. Bonus Shares or shares
    acquired through reinvestment of dividends or distributions are not subject
    to a deferred sales load.

     The deferred sales load relating to Class X shares will be waived in
certain circumstances, such as:

     - Mandated minimum post-retirement withdrawals from an IRA or other
       retirement plan if you are over 59 1/2 years old.

     - Redemptions resulting from shareholder death or disability as long as the
       waiver request is made within one year of death or disability or, if
       later, reasonably promptly following completion of probate.

     - Redemptions resulting from closure by the Fund of the account in which
       shares are held.

     To determine whether the Class X CDSL applies to a redemption, the Fund
redeems shares in the following order: (i) shares acquired by reinvestment of
dividends and capital gains distributions; (ii) shares (including Bonus Shares)
held for over six years; (iii) shares (not including Bonus Shares) in the order
they were purchased (such that shares held the longest are redeemed first); and
(iv) Bonus Shares in the order they were acquired (such that Bonus Shares held
the longest are redeemed first). In the table above, a "year" is a 12 month
period. All purchases are considered to have been made on the business day of
the month in which the purchase was made.

     If you redeem Class X shares and within 90 days buy new shares of the same
class, you will receive a credit for any CDSL paid. If such reinstated shares
are then redeemed within six years of the initial purchase, the CDSL will be
imposed upon the redemption. The amount eligible for this "Reinstatement
Privilege" may not exceed the amount of your redemption proceeds. To exercise
the privilege, contact the Funds at 1-877-INFO-ING.

     Your Class X shares convert automatically into Class A shares eight years
after purchase. Any Class X shares received through reinvestment of dividends or
distributions paid on converting shares will also convert at that time. Class A
shares are subject to lower annual expenses than Class X shares. The conversion
of Class X shares to Class A shares is not a taxable event for federal income
tax purposes.

     The minimum initial investment in a Fund is $1,000. Any subsequent
investments must be at least $50. The Distributor may waive these minimums from
time to time. All initial investments should be accompanied by a completed
Account Application. An Account Application accompanies this Prospectus. All
funds received are invested in full and fractional shares of the appropriate
Fund. Certificates for shares are not issued. Contributions to IRAs and
qualified retirement plans are subject to prevailing limits set by the Internal
Revenue Service. Your account will be charged an annual maintenance fee, but you
will not be charged more than one such fee with respect to multiple accounts of
the same plan type established under the same taxpayer identification number.
The Funds reserve the right to reject any purchase order. The Funds will accept
third party checks from qualified financial institutions, such as broker-dealers
and investment advisers that are registered with the Securities and Exchange
Commission, as well as insurance companies, banks, credit unions and thrift
companies. Personal third party checks and non-U.S. checks will not be accepted.
All initial investments may be made using any of the following methods:

                              HOW TO REDEEM SHARES

     You may redeem your shares, in whole or in part, on each day a Fund is
valued. Shares will be redeemed without charge (except any applicable CDSL) at
the net asset value next determined after a redemption request in good order has
been received by the Funds. In the instance where you own more than one class of
shares and the class of shares being redeemed are not subject to the CDSL, those
shares with the highest Rule 12b-1 fee will be redeemed in full prior to any
redemption of shares with a lower Rule 12b-1 fee.

     When purchases are made by check in any Fund, redemption proceeds will be
made available immediately upon clearance of the purchase check, which may take
up to 15 calendar days. You may avoid this delay by investing through wire
transfers of federal funds.

                                   Funds at 1-877-INFO-ING for instructions.
 Through an Authorized Broker    You may redeem your shares by contacting your authorized
 or Investment Adviser           broker or investment advisor and instructing him or her
                                 to redeem your shares. Your representative will then
                                 contact the Funds and place a redemption trade on your
                                 behalf. These organizations may impose certain
                                 restrictions on redemptions and may charge you a fee for
                                 the transaction.
</TABLE>

     The Funds reserve the right to redeem in kind. That is, the Funds may honor
redemption requests with readily marketable portfolio securities instead of cash
if during any 90-day period redemptions exceed the lesser of $250,000 or 1% of
the net assets of the redeeming Fund at the beginning of such period. You may
incur transaction costs associated with converting these securities to cash.

     Due to the high costs of maintaining small accounts, the Funds may ask that
you increase your account balance if (1) the value of your account falls below
$500 for three consecutive months as a result of redemptions or exchanges, and
(2) your account has been in existence for at least one year and you have not
made any additional purchases in the account within the preceding six calendar
months. If the account balance remains below the minimum requirement for 60 days
after you are notified, the Funds may close your account and send you the
redemption proceeds.

     Signature Guarantees.  A signature guarantee is designed to protect the
investor, the Funds and their agents by verifying the signature of certain
investors seeking to redeem, transfer, or exchange shares of the Funds.
Signature guarantees are required for:

     - redemptions by mail in excess of $50,000;

     - redemptions by mail if the proceeds are to be paid to someone other than
       the name(s) in which the account is registered;

     - redemptions requesting proceeds to be sent to a new address or an address
       that has been changed within the past 15 days;

     - requests to transfer the registration of shares to another owner; or

     - redemptions or exchanges of shares previously reported as lost/abandoned
       property, whether or not the redemption amount is under $50,000 or the
       proceeds are to be sent to the address of record.

     The foregoing requirements may be waived or modified upon notice to
shareholders.

     Acceptable guarantors include banks, broker-dealers, credit unions,
national securities exchanges, savings associations and any other organization,
provided that such institution or organization qualifies as an "eligible

                               EXCHANGE PRIVILEGE

     Class X shares of a Fund may be exchanged, based on the per share net asset
values, for Class X shares of any other Fund. You will receive credit for the
period of time you held the shares being exchanged when determining whether the
acquired shares, when redeemed, will be subject to a contingent deferred sales
load.
     Your exchange will be processed at the next determined net asset value
after the Funds receive your request. A new account opened by exchange must be
established with the same name(s), address and social security number as the
existing account.

     You may only exchange shares into a Fund which is authorized for sale in
your state of residence. The Funds may limit each account to eight exchanges per
calendar year. The Funds may change or discontinue the exchange privilege after
giving you 60 days' prior notice. An exchange of shares is a taxable event on
which you may realize a gain or loss. You may exchange shares using any of the
following methods:

</TABLE>

                               PRICING OF SHARES

     Each of the Funds prices its shares based on its net asset value. The Funds
use the amortized cost method to value its portfolio securities and seek to
maintain a constant net asset value of $1.00 per share, although there may be
circumstances under which this goal cannot be achieved.

The amortized cost method involves valuing a security at its cost and amortizing
any discount or premium over the period until maturity, regardless of the impact
of fluctuating interest rates on the market value of the security. Although the
Board of Trustees has established procedures designed to
<PAGE>   196
 10                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

stabilize, to the extent reasonably possible, the share price of the Funds,
there can be no assurance that each Fund's net asset value can be maintained at
$1.00 per share.

     Each Fund determines the net asset value of its shares as of the close of
the NYSE (normally 4:00 p.m., Eastern time) on each day the NYSE and the Federal
Reserve Bank are open for business. The price at which a purchase or redemption
is effected is based on the next calculation of a Fund's net asset value after
the order is placed.

                          DIVIDENDS AND DISTRIBUTIONS

     Each Fund intends to distribute to its shareholders substantially all of
its investment company taxable income (which includes dividends and interest and
the excess, if any, of net short-term capital gains over net long-term capital
losses). Each of the Funds will declare dividends daily and pay dividends
monthly. In addition, each Fund intends to distribute, at least annually,
substantially all of its net capital gains (the excess of net long-term capital
gains over net short-term capital losses). In determining amounts of capital
gains to be distributed, any capital loss carryovers from prior years will be
applied against capital gains.

     Dividends and distributions will be reinvested in additional shares of a
Fund at net asset value unless you elect to receive such dividends and
distributions in cash. If you redeem all or a portion of Fund shares prior to a
dividend payment date, you will be entitled on the next dividend payment date to
all dividends declared but unpaid on those shares at the time of their
redemption.

     If you elect to receive distributions in cash and the post office cannot
deliver your checks or if you do not cash your checks within six months, your
dividends may be reinvested in your account at the then-current net asset value
and your account will be converted to the reinvestment option. You will not
receive interest on the amount of your uncashed checks.

     The elections described above may be made either on the Account Application
or by calling the Fund at 1-877-INFO-ING.

                                     TAXES

     Each Fund is treated as a separate entity for federal income tax purposes.
Each Fund intends to qualify as a regulated investment company by satisfying the
requirements under Subchapter M of the Internal Revenue Code of 1986 (the
"Code"), including requirements with respect to diversification of assets,
distribution of income and sources of income. By so qualifying, each Fund
generally will not be subject to federal income tax to the extent that it
distributes investment company taxable income and net realized capital gains in
the manner required under the Code.

     Special tax treatment, including a penalty on certain pre-retirement
distributions, is accorded to accounts maintained as qualified retirement plans.
The foregoing discussion is intended for shareholders that are exempt from
federal income taxes. You should consult your own tax advisor as to the federal,
state and local tax consequences of ownership of shares of the Funds in your
particular circumstances.

                  MORE INFORMATION ABOUT STRATEGIES AND RISKS

     A Fund's risk profile is largely a factor of the principal securities in
which it invests and investment techniques that it uses. The following pages
discuss the risks associated with certain of the types of securities in which
the Funds may invest and certain of the investment practices that the Funds may
use. For more information about these and other types of securities and
investment techniques used by the Funds, see the Statement of Additional
Information. Unless indicated otherwise, the following descriptions apply to all
Funds.

     Many of the investment techniques and strategies discussed in this
Prospectus and in the Statement of Additional Information are discretionary,
which means that the Investment Manager or Sub-Adviser can decide whether to use
them or not. The Investment Manager or Sub-Adviser may also use investment
techniques or make investments in securities that are not a part of the Fund's
principal investment strategy.

     Corporate Debt Securities (ING Money Market Fund Only).  Debt securities
are subject to the risk of the issuer's inability to meet principal and interest
payments on the obligation and may also be subject to price volatility due to
such factors as interest rate sensitivity, market perception of the
credit-worthiness of the issuer and general market liquidity. When interest
rates decline, the value of the debt securities can be expected to rise, and
when interest rates rise, the value of those securities can be expected to
decline. Debt securities with longer maturities tend to be more

ING FUNDS TRUST                                                               11
- --------------------------------------------------------------------------------

sensitive to interest rate movements than those with shorter maturities.

     U.S. Government Agency Securities (ING Money Market Fund Only).  Some U.S.
Government agency securities may be subject to varying degrees of credit risk,
and all U.S. Government securities may be subject to price declines in the
securities due to changing interest rates.

     Other Investment Companies (All Funds).  Each Fund may invest up to 10% of
its assets in other unaffiliated investment companies. There is no limit with
regard to investments in affiliated investment companies. When a Fund invests in
other investment companies, you indirectly pay a proportionate share of the
expenses of that other investment company (including management fees,
administration fees, and custodial fees) in addition to the expenses of the
Fund.

     Restricted and Illiquid Securities (ING Money Market Fund Only).  Each Fund
may invest up to 10% of its net assets in restricted and illiquid securities. If
a security is illiquid, the Fund might be unable to sell the security at a time
when the sub-adviser might wish to sell, and the security could have the effect
of decreasing the overall level of the Fund's liquidity. Further, the lack of an
established secondary market may make it more difficult to value illiquid
securities, which could vary from the amount the Fund could realize upon
disposition. Restricted securities, i.e., securities subject to legal or
contractual restrictions on resale, may be illiquid. However, some restricted
securities may be treated as liquid, although they may be less liquid than
registered securities traded on established secondary markets.

     Mortgage-Related Securities (ING Money Market Fund Only).  Like other fixed
income securities, when interest rates rise, the value of a mortgage-backed
security generally will decline; however, when interest rates are declining, the
value of mortgage-backed securities with prepayment features may not increase as
much as other fixed income securities. The rate of prepayments on underlying
mortgages will affect the price and volatility of a mortgage-related security,
and may have the effect of shortening or extending the effective maturity of the
security beyond what was anticipated at the time of the purchase. Unanticipated
rates of prepayment on underlying mortgages can be expected to increase the
volatility of such securities. In addition, the value of these securities may
fluctuate in response to the market's perception of the creditworthiness of the
issuers of mortgage-related securities owned by a Fund. Additionally, although
mortgages and mortgage-related securities are generally supported by some form
of government or private guarantee and/or insurance, there is no assurance that
private guarantors or insurers will be able to meet their obligations.

     Asset-Backed Securities (ING Money Market Fund ). Asset-backed securities
involve certain risks that are not posed by mortgage-related securities,
resulting mainly from the fact that asset-backed securities often do not contain
the benefit of a complete security interest in the related collateral. The risks
associated with asset-backed securities may be reduced by the addition of credit
enhancements such as a bank letter of credit or a third-party guarantee.

     Repurchase Agreements (All Funds).  Each Fund may enter into repurchase
agreements, which involve the purchase by a Fund of a security that the seller
has agreed to buy back. If the seller defaults and the collateral value
declines, the Fund might incur a loss. If the seller declares bankruptcy, the
Fund may not be able to sell the collateral at the desired time.

     Lending Portfolio Securities (All Funds).  In order to generate additional
income, each Fund may lend portfolio securities in an amount up to 33 1/3% of
its total assets to broker-dealers, major banks, or other recognized domestic
institutional borrowers of securities. As with other extensions of credit, there
are risks of delay in recovery or even loss of rights in the collateral should
the borrower default or fail financially.

     Borrowing (All Funds).  Each Fund may borrow for certain types of temporary
or emergency purposes subject to certain limits. Borrowing may exaggerate the
effect of any increase or decrease in the value of portfolio securities or the
net asset value of a Fund, and money borrowed will be subject to interest costs.
Interest costs on borrowings may fluctuate with changing market rates of
interest and may partially offset or exceed the return earned on borrowed funds.
Under adverse market conditions, a Fund might have to sell portfolio securities
to meet interest or principal payments at a time when fundamental investment
considerations would not favor such sales.

     Fundamental and Non-Fundamental Policies (All Funds).  Unless otherwise
stated, all investment objectives and policies are non-fundamental and may be
amended without shareholder approval.

     Percentage Investment Limitations (All Funds).  Unless otherwise stated,
percentage limitations in this prospectus apply at the time of investment.

     The financial highlights table is intended to help you understand the
financial performance of the ING Money Market Fund's Class X Shares for the
fiscal period ended October 31, 1999. Certain information reflects financial
results for a single Fund share. The total returns in the table represent the
rate than an investor would have earned or lost on an investment in the Fund
(assuming reinvestment of all dividends and distributions). Past performance
does not guarantee future results. This information has been audited by Ernst &
Young LLP, independent auditors, whose report, along with the Fund's financial
statements, is included in the Statement of Additional Information, which is

(1) Class X shares commenced offering on January 20, 1999.

(2) Per share amount is based on average number of shares outstanding during the
    period.

    distributions, if any, and does not reflect the deduction of the applicable
    contingent deferred sales loads with respect to Class X shares. Total return
    for Class X shares does not include the 2.00% bonus shares paid by the

- --------------------------------------------------------------------------------

                                  STOCK FUNDS

 ING LARGE CAP GROWTH FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and will invest at least 65% of its total
assets in a portfolio of equity securities of large companies (that is,
companies with market capitalizations of more than $1 billion at the time of
acquisition), which in the Sub-Adviser's opinion possess growth potential. As a
general matter, the Fund expects these investments to be in common stocks.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, four-step investment process that seeks to identify unrecognized
growth and value in large capitalization stocks. The four steps are:

     - First, the universe of companies is screened using models developed by
       the Sub-Adviser to create a list of possible investments;

     - Second, the Sub-Adviser researches the companies identified by the
       screening models. This research includes a review of company management
       and other factors that are more subjective and require the extensive
       practical experience of the portfolio managers;

     - Third, the Sub-Adviser evaluates the return, valuation and risk of the
       remaining potential investments against a defined peer group; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.
     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities. The Fund invests primarily in equity
       securities of larger companies, which generally have more stable prices
       than smaller companies.

     - Market Trends.  From time to time, the stock market may not favor the
       large company, growth-oriented securities in which the Fund invests.
       Rather, the market could favor value stocks or small company stocks, or
       may not favor equities at all.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class I shares would have
substantially similar annual returns because the Class I shares are invested in
the same portfolio of securities and the annual returns would differ only to the
extent that Class I shares and Class A shares do not have the same expenses. For
purposes of the Average Annual Returns table, Class A shares' return reflects a
deduction of an initial sales load.

ANNUAL TOTAL RETURNS

     The following bar chart depicts changes in the performance of the Fund's
Class A shares for the year ended December 31, 1999. The bar chart does not
reflect sales loads. If it did, the annual total return shown would be lower.

 ING GROWTH & INCOME FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities. As a general matter, the Fund expects these
investments to earn income and to be in common stocks of large companies whose
market capitalizations are generally in excess of $10 billion.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, three-step investment process that seeks to identify growth at a
reasonable price. The three steps are:

     - First, the universe of companies is screened using models developed by
       the Sub-Adviser to rank possible investments;

     - Second, the Sub-Adviser researches the companies identified by the
       screening models. This research includes a review of earnings, sales and
       growth, as well as the impact of broad economic trends found within the
       economy upon possible investments;

     - Third, in order to help manage the risk of the portfolio, the
       characteristics of the portfolio are evaluated against certain market
       benchmarks.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Changes in Interest Rates.  The Fund invests in securities that produce
       income and therefore the value of its investments may rise or fall in
       response to fluctuations in interest rates. Generally, when interest
       rates increase, the value of income producing securities may decrease,
       and when interest rates decrease, the value of income producing
       securities may increase.

     - Market Trends.  From time to time, the stock market may not favor the
       income producing securities in which the Fund invests. Rather, the market
       could favor non-income producing large capitalization growth stocks,
       value stocks or small company stocks, or may not favor equities at all.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the Class I shares of
the ING Growth & Income Fund currently are not operational, there is no
performance information included in this Prospectus.

 ING MID CAP GROWTH FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of companies with market capitalizations
falling within the Russell Mid Cap Growth Index at the time of acquisition
which, in the Sub-Adviser's opinion, possess growth potential. The average
market capitalization and median market capitalization of this index as of its
latest reconstitution was $4.13 billion and $3.15 billion, respectively. As a
general matter, the Fund expects these investments to be in common stocks.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined investment process combining technical analysis and fundamental
research that seeks to identify companies with superior growth characteristics.

Sub-Adviser also follows certain self-imposed criteria in an attempt to manage
risk.

     QUANTITATIVE ANALYSIS evaluates stocks based on:

     - Market capitalizations (their size based on price and shares outstanding)

     - Minimum stock price

     - Trading history

     - Trading volume

     - Earnings growth

     - Relative financial strength

     FUNDAMENTAL RESEARCH of individual companies emphasizes:

     - Sustainable earnings growth potential

     - Strong balance sheets

     - Cash flow characteristics

     - Reasonable valuations

     - Quality management

     RISK MANAGEMENT discipline stresses:

     - Remaining fully invested at all times

     - Broad diversification among securities and industries

     - Strict adherence to established buy and sell criteria

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       mid-capitalization company, growth-oriented securities in which the Fund
       invests. Rather, the market could favor value stocks or stocks of larger
       or smaller companies, or may not favor equities at all.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the Class I shares of
the ING Mid Cap Growth Fund currently are not operational, there is no
performance information included in this Prospectus.

 ING SMALL CAP GROWTH FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of smaller companies (that is, companies
with market capitalizations falling within the Russell 2500 Growth Index at the
time of acquisition), which in the Sub-Adviser's opinion possess growth
potential. The average market capitalization and median market capitalization of
this index as of its latest reconstitution was $870 million and $580 million,
respectively. As a general matter, the Fund expects these investments to be in
common stocks.

     In choosing investments for the Fund, the Sub-Adviser employs a disciplined
investment process that combines economic analysis and extensive company
research to identify companies with superior long-term growth potential. The
investment strategy of the Sub-Adviser is as follows:

     - The Sub-Adviser reviews economic and industry trends to develop themes to
       use in the development of the overall portfolio, which in turn helps
       identify specific companies to consider.

     - With regard to companies under consideration, the Sub-Adviser next
       reviews their respective business models and management, and meets with
       senior executives. The Sub-Adviser also analyzes the company's
       price-to-earnings ratios, earnings forecasts and cash flow.

     - Companies that do not meet the expectations of the Sub-Adviser, either
       due to earnings disappointments or other fundamental criteria may be

     A more detailed discussion of the Principal Investment Strategies is
available in the SAI under "Investment Policies and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       small company, growth-oriented securities in which the Fund invests.
       Rather, the market could favor value stocks or large company stocks, or
       may not favor equities at all.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the Class I shares of
the ING Small Cap Growth Fund currently are not operational, there is no
performance information included in this Prospectus.

 ING GLOBAL BRAND NAMES FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of companies which in the
Sub-Adviser's opinion, have a well recognized franchise, a global presence and
derive most of their revenues from sales of consumer goods. The companies in
which the Fund invests either have leading market positions, or in the
Sub-Adviser's opinion, have the potential to achieve leading market positions in
the foreseeable future. This portion of the portfolio will have investments
located in at least three different countries including the United States. As a
general matter, the Fund expects these investments to be in common stocks of
large companies whose market capitalizations are generally in excess of $10
billion.

     In choosing investments for the Fund, the Sub-Adviser believes that
well-established companies with strong brand names offer the following
investment advantages:

     - First, demand for brand name products should rise as global consumer
       tastes become more uniform;

     - Second, large companies that can leverage doing business on a larger
       scale have enhanced profit potential;

     - Third, perceived product quality and reliability facilitates sales;

     - Fourth, greater recognition leads to brand loyalty; and

     - Finally, brand extensions, or the ability to leverage a company's
       established brand, provide opportunities for growth.

     The Sub-Adviser employs a two-tiered approach to structuring the Fund's
portfolio with securities that offer growth at a reasonable price. The first
tier, which will comprise about 75% of the portfolio, is composed of core stocks
with stable earnings development, low cyclicality, large market capitalizations
and longer-term investment horizons. The second tier, which will comprise about
25% of the portfolio, is composed of companies possessing higher cyclicality,
smaller market capitalizations and shorter-term investment horizons. This second
tier is expected to provide the Fund with shorter-term performance benefits.

available in the Statement of Additional Information under "Investment Policies
and Risks" section.

       decline in value due to factors affecting securities markets generally or

       security may decline for reasons relating

- --------------------------------------------------------------------------------

       to the issuer, such as changes in the financial condition of the issuer.
       Equities generally have higher volatility than debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. Rather, the market could favor
       value stocks or small company stocks, or may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the Class I shares of
the ING Global Brand Names Fund currently are not operational, there is no
performance information included in this Prospectus.

 ING INTERNATIONAL EQUITY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of issuers organized or having a majority of
their assets in or deriving a majority of their operating income in any country
throughout the world, not including the United States. This portion of the
portfolio will have investments in at least seven different countries. The Fund
may purchase securities in any foreign country, developed or underdeveloped, or
emerging market countries. The Fund will not invest more than 15% of its total
assets in emerging market countries.

     As a general matter, the Fund expects these investments to be in common
stocks of large companies whose market capitalizations are generally in excess
of $10 billion. The Fund may also use options and futures contracts involving
foreign currencies.

     In choosing investments for the Fund, the Sub-Advisers employ a highly
disciplined, four-step investment process combining top-down country allocations
with bottom-up fundamental research that seeks to identify companies which will
provide superior relative returns. The four steps are:

     - First, the Sub-Advisers perform a comprehensive analysis of the relative
       value of geographic regions to determine the degree of representation of
       such geographic regions in the Fund's portfolio;

     - Second, such determinations are reviewed by an independent committee
       within the Sub-Advisers;

     - Third, the Sub-Advisers select investments within the selected
       geographical regions based on comprehensive fundamental analysis; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities.

available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

       the Fund's underlying investments decrease. Equity securities face

       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       stocks in markets to which the Fund is not exposed, or may not favor
       equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

- --------------------------------------------------------------------------------

     - Emerging Market Risk.  To the extent the Fund invests in emerging markets
       countries, the risks may be greater, partly because emerging market
       countries may be less politically and economically stable than other
       countries. It may also be more difficult to buy and sell securities in
       emerging market countries.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

     Performance Summary.  The bar chart and tables below depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class I shares would have
substantially similar annual returns because the Class I shares are invested in
the same portfolio of securities and the annual returns would differ only to the
extent that Class I shares and Class A shares do not have the same expenses. For
purposes of the Average Annual Returns table, Class A shares' return reflects a
deduction of an initial sales load.

ANNUAL TOTAL RETURNS

     The following bar chart depicts changes in the performance of the Fund's
Class A shares for the year ended December 31, 1999. The bar chart does not
reflect sales loads. If it did, the annual total return shown would be lower.

 ING EUROPEAN EQUITY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of European issuers. The Sub-Adviser
considers European issuers to be companies whose securities are principally
traded in the European capital markets, that derive at least 50% of their total
revenues or earnings from either goods produced or services rendered in
countries located in Europe, regardless of where the securities of such
companies are principally traded, or that are organized under the laws of and
have a principal office in a European country. As a general matter, the Fund
expects these investments to be in common stocks of large companies whose market
capitalizations are generally in excess of $10 billion.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, five-step investment process that seeks to identify underpriced
earnings growth in European companies. The five steps are:

     - First, the Sub-Adviser ranks possible investments according to trading
       volume and liquidity relative to their peers.

     - Second, the Sub-Adviser performs additional screens to determine which
       companies should be further researched;

     - Third, the Sub-Adviser performs fundamental analysis of cyclical and
       non-cyclical market sectors and companies to identify underpriced
       earnings or cash flow growth.

     - Fourth, the Sub-Adviser determines portfolio weightings within each
       sector.

- --------------------------------------------------------------------------------

     - Finally, the Sub-Adviser continuously monitors the portfolio to maintain
       favorable risk-reward relationships.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in markets to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the Class I shares of
the ING European Equity Fund currently are not operational, there is no
performance information included in this Prospectus.

 ING TAX EFFICIENT EQUITY FUND

     Investment Objective.  The Fund seeks to provide taxable investors with a
high total return on an after-tax basis.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 80% of its total assets
in a portfolio of equity securities whose returns depend upon stock market
prices. The Sub-Adviser will manage the Fund's portfolio in a manner that will
attempt to reduce net realized capital gains each year. An emphasis will be
placed on common stocks of companies which the Sub-Adviser believes to have
superior appreciation potential. As a general matter, the Fund expects these
investments to be in common stocks of large, mid-sized, and small companies.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined investment process, combining macroeconomic analysis and fundamental
company research that seeks to identify growth at a reasonable price:

     - The Sub-Adviser first determines the outlook for market sectors and
       industries based on business cycle characteristics.

     The Sub-Adviser next searches for companies with improving fundamentals and
accelerating growth.

     Finally, the Sub-Adviser assesses company stock prices relative to their
expected earnings growth rates and to the overall equity markets.

     The Sub-Adviser attempts to minimize tax consequences to investors by
focusing on non-dividend paying or low-dividend paying stocks and by reducing
annual portfolio turnover.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements

       than securities of larger, more established growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more

       securities in which the Fund invests. For example, the market could favor
       value stocks or may not favor equities at all.

     - Tax Efficient Management.  The Fund is managed to provide high after-tax
       returns. Therefore, it may not provide as high a return before tax as
       other funds, and as a result may not be suitable for investors who are
       not subject to current income tax (for example, those investing through a
       tax-deferred retirement account, such as an IRA or a 401(k) Plan).

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the Class I shares of
the ING Tax Efficient Equity Fund currently are not operational, there is no
performance information included in this Prospectus.

 ING TAX EFFICIENT EQUITY VALUE FUND

     Investment Objective.  The Fund seeks to provide taxable investors with a
high total return on an after-tax basis.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 80% of its total assets
in a portfolio of equity securities determined by the Sub-Advisers to be
undervalued in the marketplace and whose returns depend upon stock market
prices. Such companies generally will have one or more of the following
attributes: (i) valuable fixed assets; (ii) valuable consumer or commercial
franchises; (iii) selling at low market valuations of assets relative to the
securities market in general, or companies that may currently be earning a very
low return on assets but which have the potential to earn higher returns if
conditions in the industry improve; (iv) are undervalued in relation to their
potential for growth in earnings, dividends, and book value; or (v) have
recently changed management or control and have the potential for a "turnaround"
in earnings. The Sub-Advisers will manage the Fund's portfolio in a manner that
will attempt to reduce net realized capital gains each year. As a general
matter, the Fund expects these investments to be in common of large, mid-sized,
and small companies.

     In choosing investments for the Fund, the Sub-Advisers employ a highly
disciplined investment process, combining macroeconomic analysis and fundamental
company research that seeks to identify undervalued companies:

     - The Sub-Advisers first determine the outlook for market sectors and

Equity Value Fund has not yet commenced operations, there is no performance
information included in this Prospectus.

 ING FOCUS FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest in a portfolio of 20 to 40
equity securities. As a general matter, the Fund expects these investments to be
in common stocks of large, mid-sized, and small companies.

     The Sub-Adviser seeks to invest the Fund in growth companies that are
positioned to benefit from capitalizing on significant industry, regulatory,
technological, and ownership changes. To find such companies, the Sub-Adviser
looks for management teams with entrepreneurial spirit and a proven talent for
creating value, with a focus on industries expected to drive change in other
industries (for example, technology and financial services). The Sub-Adviser's
investment strategy incorporates the following elements to identify companies
that offer growth at a reasonable price:

     - The Sub-Adviser performs fundamental economic and business research to
       identify investment themes expected to improve returns on capital and
       drive earnings growth within industries.

     - The Sub-Adviser next analyzes individual companies to identify favorable:

       -- Business characteristics, including industry structure and trends

       -- Financial performance, both historical and projected

       -- Valuations in both absolute and relative terms

     - The Sub-Adviser continues to monitor previously identified companies to
       track changes in critical variables as well as price fluctuations.

     - The Sub-Adviser sets specific limits on individual holdings and sector
       concentrations.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       growth-oriented securities in which the Fund invests. Rather, the market
       could favor value stocks or may not favor equities at all.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest

- --------------------------------------------------------------------------------

       a greater percentage of its assets in a particular issuer. The investment
       of a large percentage of the Fund's assets in the securities of a small
       number of issuers may cause the Fund's share price to fluctuate more than
       that of a diversified investment company.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the Class I shares of
the ING Focus Fund currently are not operational, there is no performance
information included in this Prospectus.

 ING GLOBAL INFORMATION TECHNOLOGY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of information technology companies. The
Fund defines information technology companies as those companies that derive at
least 50% of their total revenues or earnings from information technology,
hardware or software, or related consulting and services industries. This
portion of the portfolio will have investments located in at least three
different countries, including the United States. As a general matter, the Fund
expects these investments to be in common stocks of large, mid-sized, and small
companies.

     The Sub-Adviser believes that because of rapid advances in information
technology, investment in companies within this sector should offer substantial
opportunities for long-term capital appreciation. The information technology
area has exhibited and continues to demonstrate rapid growth, both through
increasing demand for existing products and services and the broadening of the
technology market. Generally, the Sub-Adviser's overall stock selection for the
Fund will be based on an assessment of the company's fundamental prospects. The
Sub-Adviser anticipates, however, that a portion of the Fund's holdings will be
invested in newly issued securities being sold in the primary or secondary
market.

     The Sub-Adviser combines broad industry analysis and bottom-up company
analysis to identify the stocks of companies it believes will become tomorrow's
information technology leaders. In choosing investments for the Fund, the
Sub-Adviser first identifies themes that address industry and technological
changes. Using intensive fundamental research, the Sub-Adviser then analyzes
individual companies worldwide to find those firms most likely to benefit from
the selected investment themes.

       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in industries to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to a

- --------------------------------------------------------------------------------

       particular industry, the Fund may be subject to greater market
       fluctuation than a fund which has securities representing a broader range
       of investment alternatives.

     - Information Technology Risk.  Information technology companies are
       generally subject to the rate of change in technology, which is higher
       than other industries. In addition, products and services of companies
       engaged in the information technology industry are subject to relatively
       high risks of rapid obsolescence caused by scientific and technological
       advances. Swings in investor psychology or significant trading by large
       institutional investors can result in significant price fluctuations and
       stock price declines.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the Class I shares of
the ING Global Information Technology Fund currently are not operational, there
is no performance information included in this Prospectus.

 ING GLOBAL COMMUNICATIONS FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of communications companies. This portion of
the portfolio will have investments located in at least three different
countries, including the United States. As a general matter, the Fund expects
these investments to be in common stocks of large, mid-sized, and small
companies.

     The Fund considers communications companies to be those that derive at
least 50% of their total revenues or earnings from designing, developing,
operating, financing, manufacturing or providing the following activities,
products and services: communications equipment and service (including equipment
and services for both data and voice transmission); electronic components and
equipment; broadcast (including television and radio, satellite, microwave and
cable television); computer equipment, mobile telecommunications and cellular
radio and paging; electronic mail; local and wide area networking and linkage of
work and data processing systems (collectively, "communications activities").

     The Sub-Adviser believes that because of rapid advances in communications,
investment in companies within this sector should offer substantial
opportunities for long-term capital appreciation. The communications area has
exhibited and continues to demonstrate rapid growth, both through increasing
demand for existing products and services and the broadening of the technology
market. Generally, the Sub-Adviser's overall stock selection for the Fund will
be based on an assessment of the company's fundamental prospects. The
Sub-Adviser anticipates, however, that a portion of the Fund's holdings will be
invested in newly issued securities being sold in the primary or secondary
market.

     The Sub-Adviser combines broad industry analysis and bottom-up company
analysis to identify the stocks of companies it believes will become tomorrow's
communications leaders. In choosing investments for the Fund, the Sub-Adviser
first identifies themes that address industry and technological changes. Using

companies worldwide to find those firms most likely to benefit from the selected
investment themes.

       or erratic market movements than securities of larger, more established
       growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in industries to which the Fund is not exposed, or

       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to a particular industry, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives.

     - Communications Technology Risk.  Communications companies are generally
       subject to the rate of change in technology, which is higher than other
       industries. In addition, products and services of companies engaged in
       the communications industry are subject to relatively high risks of rapid
       obsolescence caused by scientific and technological advances. Swings in
       investor psychology or significant trading by large institutional
       investors can result in significant price fluctuations and stock price
       declines.

     - Governmental Regulation.  Certain communications industries, such as the
       telecommunications industry, may be subject to greater governmental
       regulation than many other industries. Accordingly, such industries may
       be subject to changes in governmental policies and the need for
       regulatory approvals may have a material effect on the products and
       services offered. Telephone operating companies in the United States, for
       example, are subject to both federal and state regulation affecting
       permitted rates of return and the kinds of services that may be offered.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Global
Communications Fund has not yet commenced operations, there is no performance
information included in this Prospectus.

 ING INTERNET FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of U.S. and non-U.S. internet
technology companies. The Fund defines internet technology companies as those
companies with internet businesses or internet related consulting or services
businesses, or that derive at least 50% of their total revenues or earnings from
business operations in internet related hardware, software or infrastructure
industries. As a general matter, the Fund expects these investments to be in
common stocks of large, mid-sized, and small companies.

     The Sub-Adviser believes that the internet is in the early stages of a
period of promising growth. The internet has enabled companies to tap into new
markets, use new distribution channels and do business with end users of their
products all over the world without having to go through wholesalers and
distributors. The Sub-Adviser believes that investment in companies related to
the internet should offer substantial opportunities for long-term capital
appreciation. Generally, the Sub-Adviser's overall stock selection for the Fund
will be based on an assessment of a company's fundamental prospects. The
Sub-Adviser anticipates, however, that a portion of the Fund's holdings will be
invested in newly issued securities being sold in the primary or secondary
market.

     In choosing investments for the Fund, the Sub-Adviser first identifies
themes which it believes will drive the internet in the future. Then, by
conducting extensive fundamental research, the Sub-Adviser analyzes individual
companies worldwide to identify those firms that are most likely to benefit from
the selected investment themes.

       value of a security may decline for reasons relating to the issuer, such
       as changes in the financial condition of the issuer. Equities generally
       have higher volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in industries to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange

 ING BALANCED FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  The Fund primarily invests in a
combination of mid- and large-capitalization equity securities, intermediate
maturity fixed income securities and money market instruments. Equity
securities, which include common and preferred stocks, warrants and convertible
securities, are acquired for capital appreciation or a combination of capital
appreciation and income. Fixed income securities, which include investment grade
corporate debt obligations (for example, rated at least BBB by Standard & Poor's
Rating Group or Baa by Moody's Investor Services) and U.S. Government
securities, are acquired for income and secondarily for capital appreciation.
Money market instruments mature in 13 months or less from the date of purchase
and include U.S. Government securities and corporate debt securities (including
those subject to repurchase agreements), certificates of deposit, bankers
acceptances and commercial paper. . The Fund may also invest in mortgage-backed
securities and asset-backed debt securities and use options and futures
contracts involving securities, securities indices, and interest rates. The Fund
will operate as a diversified fund.

     The percentage of assets invested in equities, fixed income securities and
money market instruments will vary from time to time depending upon the
Sub-Adviser's judgment of general market and economic conditions, trends in
yields and interest rates and changes in fiscal or monetary policies. Depending
upon the Sub-Adviser's determination of market and economic conditions,
investment emphasis may be placed on equities or fixed income securities. The
allocation between equities and fixed income securities creates an opportunity
for investors to receive competitive returns of capital growth and income while
maintaining diversification. Under normal market conditions, the Fund will
invest at least 25% of its total assets in fixed income securities. The average
maturity of the fixed income securities held by the Fund will normally
approximate five years, although this will vary with changing market conditions
and opportunities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Equity Investments.  Equity securities face market, issuer and
       other risks, and their values may go down, sometimes rapidly and
       unpredictably. Market risk is the risk that securities may decline in
       value due to factors affecting securities markets generally or particular
       industries. Issuer risk is the risk that the value of a security may
       decline for reasons relating to the issuer, such as changes in the
       financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

       Interest Rate Risk -- In general, when interest rates go up, prices of
       fixed income securities go down.

       Default Risk -- An issuer of a security may default on its obligation to
       pay principal and/or interest.

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk -- An issuer of a security may prepay principal
       earlier than scheduled, which could force the Fund to reinvest in lower
       yielding securities.

       Extension Risk -- Slower than expected principal payments on a
       mortgage-backed or asset-backed security may extend such security's life,
       thereby locking in a below-market interest rate, increasing the
       security's duration and reducing the value of the security.

     - Allocation Risk.  The Sub-Adviser's judgment about the attractiveness and
       risk adjusted return potential of particular asset classes may prove to
       be wrong. By utilizing the balanced approach described herein, the Fund's
       net asset value may not rise as rapidly or as much as the stock market
       during cycles of rising stock prices.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

 ING EMERGING MARKETS EQUITY FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of equity securities of emerging market issuers. The Fund will
typically maintain investments in at least seven emerging market countries and
will not invest more than 25% of its total assets in any one emerging market
country. The Fund defines an emerging market country as any country the economy
and market of which the World Bank or the United Nations considers to be
emerging or developing or any country determined by the Sub-Advisers to have
emerging economies or developing markets. The Fund considers
<PAGE>   220
ING FUNDS TRUST                                                               19
- --------------------------------------------------------------------------------

emerging market issuers to be companies the securities of which are principally
traded in the capital markets of emerging market countries; that derive at least
50% of their total revenue or earnings from either goods produced or services
rendered in emerging market countries, regardless of where the securities of
such companies are principally traded; or that are organized under the laws of
and have a principal office in an emerging market country.

     As a general matter, the Fund expects these investments to be in common
stocks of large, mid-sized, and small companies. The Fund may also use options
and futures contracts involving foreign currencies.

     In choosing investments for the Fund, the Sub-Advisers employ a highly
disciplined, four-step investment process that seeks to identify unrecognized
growth potential in stocks of emerging market issuers. The four steps are:

     - First, the Sub-Advisers perform a comprehensive analysis of the relative
       value of geographic regions to determine the degree of representation of
       such geographic regions in the Fund's portfolio;

     - Second, such determinations are reviewed by an independent committee
       within the Sub-Advisers;

     - Third, the Sub-Advisers select investments within the selected
       geographical regions based on comprehensive fundamental analysis; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks of companies located in more developed countries,
       or may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Emerging Market Risk.  Because the Fund invests primarily in emerging
       market countries, the risks may be greater, partly because emerging
       market countries may be less politically and economically stable than
       other countries. It may also be more difficult to buy and sell securities
       in emerging market countries.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Emerging

 ING GLOBAL REAL ESTATE FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of companies that are principally
engaged in the real estate industry. In selecting investments for the Fund, the
Sub-Advisers will select companies that derive at least 50% of their total
revenues or earnings from owning, operating, developing and/or managing real
estate. This portion of the portfolio will have investments located in at least
three different countries including the United States. As a general matter, the
Fund expects these investments to be in common stocks and real estate investment
trusts of large, mid-sized, and small companies.

     The Sub-Advisers use a disciplined two-step process for constructing the
Fund's portfolio:

     - First, the Sub-Advisers select sectors and geographic regions in which to
       invest, and determine the degree of representation of such sectors and
       regions, through a systematic evaluation of public and private property
       market trends and conditions.

     - Second, the Sub-Advisers use an in-house valuation process to identify
       investments with superior current income and growth potential relative to
       their peers. This in-house valuation process examines several factors
       including: (i) value and property; (ii) capital structure; and (iii)
       management and strategy.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities. In addition, when interest rates
       increase, the value of income producing equity securities may decrease,
       and when interest rates decrease, the value of income producing equity
       securities may increase.

     - Mid-Sized Companies.  Investments in mid-sized companies involve greater
       risk than is customarily associated with larger, more established
       companies due to the greater business risks of smaller size, more limited
       markets and financial resources, narrower product lines and less depth of
       management. The securities of mid-sized companies may be subject to more
       volatile market movements than securities of larger, more established
       growth companies.

     - Small Companies.  Investments in small companies involve greater risk
       than is customarily associated with larger, more established companies
       due to the greater business risks of small size, limited markets and
       financial resources, narrow product lines and the frequent lack of depth
       of management. The securities of smaller companies may be subject to more
       abrupt or erratic market movements than securities of larger, more
       established growth companies.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. Rather, the market could favor
       stocks in industries to which the Fund is not exposed, or may not favor
       equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to a particular industry, the Fund may be subject
       to greater market fluctuation than a fund which has securities
       representing a broader range of investment alternatives.

     - Real Estate Risk.  Investments in issuers that are principally engaged in
       real estate, including real estate investment trusts ("REITs"), may
       subject the
<PAGE>   222
ING FUNDS TRUST                                                               21
- --------------------------------------------------------------------------------

       Fund to risks similar to those associated with the direct ownership of
       real estate (in addition to securities market risks). These companies are
       sensitive to factors such as changes in real estate values and property
       taxes, interest rates, cash flow of underlying real estate assets, supply
       and demand, and the management skill and creditworthiness of the issuer.
       REITs may also be affected by tax and regulatory requirements.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the ING Global Real
Estate Fund has not yet commenced operations, there is no performance

 ING QUALITY OF LIFE FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
capital appreciation.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of equity securities of U.S. and non-U.S. quality of life
companies. The Fund defines quality of life companies as those companies that
derive at least 50% of their total revenues or earnings from offering products
and services helping persons live longer, healthier and happier lives. Such
companies may include, but will not be limited to, companies engaged in the
research, development, production or distribution of products or services
related to health care (for example, pharmaceutical and consumer goods
companies, biotechnology companies, and health maintenance organization
companies); companies engaged in providing entertainment services or equipment
related to leisure time activities (for example, travel and leisure companies
and sports equipment companies); and companies providing other services or
products desired by the aging baby boomer population (for example, retirement
community development companies). As a general matter, the Fund expects these
investments to be in common stocks of large companies whose market
capitalizations are generally in excess of $10 billion.

     The Sub-Adviser believes that quality of life companies will benefit from
the aging baby boomer generation. The global consumption pattern is steadily
changing as a result of an increase in wealth and a resulting increase in life
expectancy. Especially in the developed countries, the population is rapidly
aging. In the opinion of the Sub-Adviser this development will lend to a
structural increase in healthcare spending. At the same time the growing group
of aging people will have an increasing need for various services and more and
new possibilities of leisure activities. People will be increasingly willing to
invest in their quality of life aiming at longer, healthier and happier lives.

     In choosing investments for the Fund, the Sub-Adviser first identifies
themes which it believes will drive the healthcare, leisure and other industries
benefiting from the aging baby boomer generation. Then, by conducting extensive
fundamental research, the Sub-Adviser analyzes individual companies worldwide to
identify those firms that are most likely to benefit from the selected
investment themes.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease. Equity securities face
       market, issuer and other risks, and their values may go down, sometimes
       rapidly and unpredictably. Market risk is the risk that securities may
       decline in value due to factors affecting securities markets generally or
       particular industries. Issuer risk is the risk that the value of a
       security may decline for reasons relating to the issuer, such as changes
       in the financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

     - Market Trends.  From time to time, the stock market may not favor the
       securities in which the Fund invests. For example, the market could favor
       value stocks or stocks in industries to which the Fund is not exposed, or
       may not favor equities at all.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the

       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of issuers may cause the Fund's share price to
       fluctuate more than that of a diversified investment company.

     - Industry Concentration.  As a result of the Fund concentrating its assets
       in securities related to

- --------------------------------------------------------------------------------

       particular industries, the Fund may be subject to greater market
       fluctuation than a fund which has securities representing a broader range
       of investment alternatives. Swings in investor psychology or significant
       trading by large institutional investors can result in significant price
       fluctuations and stock price declines.

EXAMPLES

     These Examples are intended to help you compare the cost of investing in
the Funds with the cost of investing in other mutual funds. Each Example assumes
that:

     - you invest $10,000 in Class I shares of each Fund for the time period
       indicated;

     - your investment has a 5% return each year;

     - the Fund's operating expenses remain the same, except for the expiration
       of the contractual expense limitations on October 31, 2000; and

     - you redeem all of your shares at the end of the time period indicated.
       The following expenses would be the same without redemption.

     Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

if during any 90-day period redemptions exceed the lesser of $250,000 or 1% of
the net assets of the redeeming Fund at the beginning of such period. You may
incur transaction costs associated with converting these securities to cash.

     Due to the high costs of maintaining small accounts, the Funds may ask that
you increase your account balance if (1) the value of your account falls below
$500 for three consecutive months as a result of redemptions or exchanges, and
(2) your account has been in existence for at least one year and you have not
made any additional purchases in the account within the preceding six calendar
months. If the account balance remains below the minimum requirement for 60 days
after you are notified, the Funds may close your account and send you the
redemption proceeds.

     Signature Guarantees.  A signature guarantee is designed to protect the
investor, the Funds and their agents by verifying the signature of certain
investors seeking to
redeem, transfer, or exchange shares of the Funds. Signature guarantees are
required for:

     - redemptions by mail in excess of $50,000;

     - redemptions by mail if the proceeds are to be paid to someone other than
       the name(s) in which the account is registered;

     - redemptions requesting proceeds to be sent to a new address or an address
       that has been changed within the past 15 days;

     - requests to transfer the registration of shares to another owner; or

     - redemptions or exchanges of shares previously reported as lost/abandoned
       property, whether or not the redemption amount is under $50,000 or the
       proceeds are to be sent to the address of record.

     The foregoing requirements may be waived or modified upon notice to
shareholders.

     Acceptable guarantors include banks, broker-dealers, credit unions,
national securities exchanges, savings associations and any other organization,
provided that such institution or organization qualifies as an "eligible
guarantor institution" as that term is defined in rules adopted by the
Securities and Exchange Commission. For information regarding whether a
particular institution or organization qualifies as an "eligible guarantor
institution," contact the Funds at 1-877-INFO-ING.

                               EXCHANGE PRIVILEGE

     Class I shares of a Fund may be exchanged, based on the per share net asset
values, for Class I shares of any other Fund. Your exchange will be processed at
the next determined net asset value after the Funds receive your request. A new
account opened by exchange must be established with the same name(s), address
and social security number as the existing account.

     You may only exchange shares into a Fund which is authorized for sale in
your state of residence. The Funds may limit each amount to eight exchanges per
calendar year. The Funds may change or discontinue the exchange privilege after
giving you 60 days' prior notice. An exchange of shares is a taxable event on
which you may realize a gain or loss. You may exchange shares using any of the
following methods:

ING FUNDS TRUST                                                               33
- --------------------------------------------------------------------------------

                               PRICING OF SHARES

     Each of the Funds prices its shares based on its net asset value. The Funds
value portfolio securities for which market quotations are readily available at
market price. These Funds value 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 Funds may value the security at its fair value as determined
in good faith by or under the supervision of the Board of Trustees. The effect
of using fair value pricing is that a Fund's net asset value will be subject to
the judgment of the Board of Trustees or its designee instead of being
determined by the market. Because some of the Funds may invest in securities
that are primarily listed on foreign exchanges, the value of those Funds' shares
may change on days when you will not be able to purchase or redeem shares.

     Each Fund determines the net asset value of its shares as of the close of
the NYSE (normally 4:00 p.m., Eastern time) on each day the NYSE is open for
business. The price at which a purchase or redemption is effected is based on
the next calculation of a Fund's net asset value after the order is placed.

                          DIVIDENDS AND DISTRIBUTIONS

     Each Fund intends to distribute to its shareholders substantially all of
its investment company taxable income (which includes dividends and interest and
the excess, if any, of net short-term capital gains over net long-term capital
losses). Each of the Funds will declare and pay these dividends annually, except
for the ING Growth & Income Fund, ING Global Real Estate Fund, and the ING
Balanced Fund, which will declare and pay dividends quarterly. In addition, each
Fund intends to distribute, at least annually, substantially all of its net
capital gains (the excess of net long-term capital gains over net short-term
capital losses). In determining amounts of capital gains to be distributed, any
capital loss carryovers from prior years will be applied against capital gains.

     Dividends and distributions will be reinvested in additional shares of a
Fund at net asset value. If you redeem all or a portion of Fund shares prior to
a dividend payment date, you will be entitled on the next dividend payment date
to all dividends declared but unpaid on those shares at the time of their
redemption.

                                     TAXES

     Each Fund is treated as a separate entity for federal income tax purposes.
Each Fund intends to qualify as a regulated investment company by satisfying the
requirements under Subchapter M of the Internal Revenue Code of 1986 (the
"Code"), including requirements with respect to diversification of assets,
distribution of income and sources of income. By so qualifying, each Fund
generally will not be subject to federal income tax to the extent that it
distributes investment company taxable income and net realized capital gains in
the manner required under the Code.

     Investment income received by a Fund from sources within foreign countries
may be subject to foreign income taxes withheld at the source. Such withholding
taxes may be reduced or eliminated under the terms of applicable United States
income tax treaties, and the Funds intend to undertake any procedural steps
required to claim the benefits of such treaties.

     Under the backup withholding rules of the Code, you may be subject to 31%
withholding of federal income tax on ordinary income dividends paid by a Fund.
In order to avoid this backup withholding, you must provide the Funds with a
correct taxpayer identification number or certify that you are otherwise exempt
from or not subject to backup withholding.

     Special tax treatment, including a penalty on certain pre-retirement
distributions, is accorded to accounts maintained as qualified retirement plans.
The foregoing discussion is intended for shareholders that are exempt from
federal income taxes. You should consult your own tax advisor as to the federal,
state and local tax consequences of ownership of shares of the Funds in your
particular circumstances.

                  MORE INFORMATION ABOUT STRATEGIES AND RISKS

     A Fund's risk profile is largely a factor of the principal securities in
which it invests and investment techniques that it uses. The following pages
discuss the risks associated with certain of the types of securities in which
the Funds may invest and certain of the investment practices that the Funds may
use. For more information about these and other types of securities and
investment techniques used by the Funds, see the Statement of Additional
Information. Unless indicated otherwise, the following descriptions apply to all
Funds.

     Many of the investment techniques and strategies discussed in this
Prospectus and in the Statement of Additional Information are discretionary,
which means that the Investment Manager or Sub-Adviser can decide whether to use
them or not. The Investment Manager or Sub-Adviser may also use investment
techniques or make investments in securities that are not a part of the Fund's
principal investment strategy.

     Temporary Defensive Strategies (All Funds).  When the Investment Manager or
Sub-Adviser to a Fund anticipates unusual market or other conditions, the Fund
may temporarily depart from its principal investment strategies. Under such
circumstances, up to 100% of the Fund's assets may be invested in investment
grade fixed income securities (for example, rated at least BBB by Standard &
Poor's Rating Group or Baa by Moody's Investor Services), money market
securities, certificates of deposit, bankers' acceptances, commercial paper or
in any other securities which in either the Investment Manager's or
Sub-Adviser's opinion are more conservative than the types of securities in
which the Fund typically invests. To the extent a Fund is engaged in temporary
defensive investments, it will not be pursuing its investment objective.

     Investments in Foreign Securities (All Funds).  There are certain risks in
owning foreign securities, including those resulting from: fluctuations in
currency exchange rates; devaluation of currencies; political or economic
developments and the possible imposition of currency exchange blockages or other
foreign governmental laws or restrictions; reduced availability of public
information concerning issuers; accounting, auditing and financial reporting
standards or other regulatory practices and requirements that are not uniform
when compared to those applicable to domestic companies; settlement and
clearance procedures in some countries that may not be reliable and can result
in delays in settlement; higher transaction and custody expenses than for
domestic securities; and limitations on foreign ownership of equity securities.
Also, securities of many foreign companies may be less liquid and the prices
more volatile than those of domestic companies. With certain foreign countries,
there is the possibility of expropriation, nationalization, confiscatory
taxation and limitations on the use or removal of funds or other assets of the
Funds, including the withholding of dividends.

     Each Fund that invests in foreign securities may enter into foreign
currency transactions either on a spot or cash basis at prevailing rates or
through forward foreign currency exchange contracts in order to have the
necessary currencies to settle transactions or to help protect the Fund against
adverse changes in foreign currency exchange rates. Such efforts could limit
potential gains that might result from a relative increase in the value of such
currencies, and might, in certain cases, result in losses to the Fund.

     Emerging Market Investments (ING International Equity Fund and ING Emerging
Markets Equity Fund).  Because of less developed markets and economies and, in
some countries, less mature governments and governmental institutions, the risks
of investing in foreign securities can be intensified in the case of investments
in issuers domiciled or doing substantial business in emerging market countries.
These risks include: high concentration of market capitalization and trading
volume in a small number of issuers representing a limited number of industries,
as well as a high concentration of investors and financial intermediaries;
political and social uncertainties; over-dependence on exports, especially with
respect to primary commodities, making these economies vulnerable to changes in
commodity prices; overburdened infrastructure and obsolete financial systems;
environmental problems; less well developed legal systems; and less reliable
custodial services and settlement practices.

     Corporate and Municipal Debt Securities (All Funds). Corporate debt
securities are subject to the risk of the issuer's inability to meet principal
and interest payments on the obligation and may also be subject to price
volatility due to such factors as interest rate sensitivity, market perception
of the credit-worthiness of the issuer and general market liquidity. When
interest rates decline, the value of the debt securities can be expected to
rise, and when interest rates rise, the value of those securities can be
expected to decline. Debt securities with longer maturities tend to be more
sensitive to interest rate movements than those with shorter maturities.

     Initial Public Offerings (All Funds).  A significant portion of a Fund's
return may be attributable to its investment in initial public offerings. When a
Fund's asset base is small, the impact of such investments on a Fund's return
will be magnified. As the Fund's assets grow, it is probable that the effect of
the Fund's investment in initial public offerings on the Fund's total return
will decline.

     U.S. Government Securities (All Funds).  Some U.S. Government agency
securities may be subject to varying degrees of credit risk, and all U.S.
Government securities
<PAGE>   236
ING FUNDS TRUST                                                               35
- --------------------------------------------------------------------------------

may be subject to price declines in the securities due to changing interest
rates.

     Convertible Securities (All Funds).  The price of a convertible security
will normally fluctuate in some proportion to changes in the price of the
underlying equity security, and as such is subject to risks relating to the
activities of the issuer and general market and economic conditions. The income
component of convertible securities causes fluctuations based upon changes in
interest rates and the credit quality of the issuer. Convertible securities are
often lower rated securities. A Fund may be required to redeem or convert a
convertible security before the holder would otherwise choose.

     Other Investment Companies (All Funds).  Each Fund may invest up to 10% of
its assets in other unaffiliated investment companies. There is no limit with
regard to investments in affiliated investment companies. When a Fund invests in
other investment companies, you indirectly pay a proportionate share of the
expenses of that other investment company (including management fees,
administration fees, and custodial fees) in addition to the expenses of the
Fund.

     Restricted and Illiquid Securities (All Funds).  Each Fund may invest up to
15% of its net assets in restricted and illiquid securities. If a security is
illiquid, the Fund might be unable to sell the security at a time when the
sub-adviser might wish to sell, and the security could have the effect of
decreasing the overall level of the Fund's liquidity. Further, the lack of an
established secondary market may make it more difficult to value illiquid
securities, which could vary from the amount the Fund could realize upon
disposition. Restricted securities, i.e., securities subject to legal or
contractual restrictions on resale, may be illiquid. However, some restricted
securities may be treated as liquid, although they may be less liquid than
registered securities traded on established secondary markets.

     Mortgage-Related Securities (All Funds).  Although mortgage loans
underlying a mortgage-backed security may have maturities of up to 30 years, the
actual average life of a mortgage-backed security typically will be
substantially less because the mortgages will be subject to normal principal
amortization, and may be prepaid prior to maturity. Like other fixed income
securities, when interest rates rise, the value of a mortgage-backed security
generally will decline; however, when interest rates are declining, the value of
mortgage-backed securities with prepayment features may not increase as much as
other fixed income securities. The rate of prepayments on underlying mortgages
will affect the price and volatility of a mortgage-related security, and may
have the effect of shortening or extending the effective maturity of the
security beyond what was anticipated at the time of the purchase. Unanticipated
rates of prepayment on underlying mortgages can be expected to increase the
volatility of such securities. In addition, the value of these securities may
fluctuate in response to the market's perception of the creditworthiness of the
issuers of mortgage-related securities owned by a Fund. Additionally, although
mortgages and mortgage-related securities are generally supported by some form
of government or private guarantee and/or insurance, there is no assurance that
private guarantors or insurers will be able to meet their obligations.

     Asset-Backed Securities (All Funds).  Asset-backed securities involve
certain risks that are not posed by mortgage-related securities, resulting
mainly from the fact that asset-backed securities often do not contain the
benefit of a complete security interest in the related collateral. The risks
associated with asset-backed securities may be reduced by the addition of credit
enhancements such as a bank letter of credit or a third-party guarantee.

     Derivatives (All Funds).  Generally, derivatives can be characterized as
financial instruments whose performance is derived, at least in part, from the
performance of an underlying asset or assets. Some derivatives are sophisticated
instruments that typically involve a small investment of cash relative to the
magnitude of risks assumed. These may include swap agreements, options, forwards
and futures. Derivative securities are subject to market risk, which could be
significant for those that have a leveraging effect. Many of the Funds do not
invest in these types of derivatives, so please check the description of the
Fund's policies found in the Statement of Additional Information. Derivatives
are also subject to credit risks related to the counterparty's ability to
perform, and any deterioration in the counterparty's creditworthiness could
adversely affect the instrument. A risk of using derivatives is that the adviser
might imperfectly judge the market's direction. For instance, if a derivative is
used as a hedge to offset investment risk in another security, the hedge might
not correlate to the market's movements and may have unexpected or undesired
results, such as a loss or a reduction in gains.

     Dollar Roll Transactions (All Funds).  The Funds may enter into dollar roll
transactions wherein the Fund sells fixed income securities, typically
mortgage-backed securities, and makes a commitment to purchase similar, but not
identical, securities at a later date from the same party. Like a forward
commitment, during the roll period no payment is made for the securities
purchased and no interest or principal payments on the security accrue to the
purchaser, but a Fund assumes the risk of ownership. A Fund is compensated for
entering into dollar roll transactions by the difference between the current
sales price and the forward price for the future purchase, as well as by the
interest earned on the cash proceeds of the initial sale. Like other when-issued
securities or firm commitment agreements, dollar roll transactions involve the
risk that the market value of the securities sold by the Funds may decline below
the price at which a Fund is committed to purchase similar securities. In the
event the buyer of securities under a dollar roll transaction becomes insolvent,
the Funds' use of the
<PAGE>   237

- --------------------------------------------------------------------------------

proceeds of the transaction may be restricted pending a determination by the
other party, or its trustee or receiver, whether to enforce the Funds'
obligation to repurchase the securities.

     Repurchase Agreements (All Funds).  Each Fund may enter into repurchase
agreements, which involve the purchase by a Fund of a security that the seller
has agreed to buy back. If the seller defaults and the collateral value
declines, the Fund might incur a loss. If the seller declares bankruptcy, the
Fund may not be able to sell the collateral at the desired time.

     Lending Portfolio Securities (All Funds).  In order to generate additional
income, each Fund may lend portfolio securities in an amount up to 33 1/3% of
its total assets to broker-dealers, major banks, or other recognized domestic
institutional borrowers of securities. As with other extensions of credit, there
are risks of delay in recovery or even loss of rights in the collateral should
the borrower default or fail financially.

     Borrowing (All Funds).  Each Fund may borrow for certain types of temporary
or emergency purposes subject to certain limits. Borrowing may exaggerate the
effect of any increase or decrease in the value of portfolio securities or the
net asset value of a Fund, and money borrowed will be subject to interest costs.
Interest costs on borrowings may fluctuate with changing market rates of
interest and may partially offset or exceed the return earned on borrowed funds.
Under adverse market conditions, a Fund might have to sell portfolio securities
to meet interest or principal payments at a time when fundamental investment
considerations would not favor such sales.

     Reverse Repurchase Agreements (All Funds).  A reverse repurchase agreement
involves the sale of a security, with an agreement to repurchase the same
securities at an agreed upon price and date. Whether such a transaction produces
a gain for a Fund depends upon the costs of the agreements and the income and
gains of the securities purchased with the proceeds received from the sale of
the security. If the income and gains on the securities purchased fail to exceed
the costs, net asset value will decline faster than otherwise would be the case.
Reverse repurchase agreements, as leveraging techniques, may increase a Fund's
yield; however, such transactions may result in a shareholder's loss of
principal.

     Short Sales (ING International Equity Fund and ING Emerging Markets Equity
Fund).  A "short sale" is the sale by a Fund of a security which has been
borrowed from a third party on the expectation that the market price will drop.
If the price of the security rises, the Fund may have to cover its short
position at a higher price than the short sale price, resulting in a loss.

     Investments in Small- and Mid-Capitalization Companies (All Funds).  The
Funds may invest in small and mid capitalization companies. Investments in mid-
and small-capitalization companies involve greater risk than is customarily
associated with larger, more established companies due to the greater business
risks of small size, limited markets and financial resources, narrow product
lines and the frequent lack of depth of management. The securities of smaller
companies are often traded over-the-counter and may not be traded in volumes
typical on a national securities exchange. Consequently, the securities of
smaller companies may have limited market stability and may be subject to more
abrupt or erratic market movements than securities of larger, more established
growth companies or the market averages in general.

     Non-diversified Investment Companies (ING Global Brand Names Funds, ING
Focus Fund, ING Global Real Estate Fund, ING Internet Fund, ING Internet Fund II
and ING Quality of Life Fund).  Certain Funds are classified as non-diversified
investment companies under the 1940 Act, which means that each Fund is not
limited by the 1940 Act in the proportion of its assets that it may invest in
the obligations of a single issuer. The investment of a large percentage of a
Fund's assets in the securities of a small number of issuers may cause that
Fund's share price to fluctuate more than that of a diversified investment
company.

     Concentration (ING Global Information Technology Fund, ING Global
Communications Fund, ING Internet Fund, ING Internet Fund II, ING Global Real
Estate Fund and ING Quality of Life Fund).  Certain Funds "concentrate" (for
purposes of the 1940 Act) their assets in securities related to a particular
sector or industry, which means that at least 25% of its assets will be invested
in these assets at all times. As a result, each Fund may be subject to greater
market fluctuation than a fund which has securities representing a broader range
of investment alternatives.

     Fundamental and Non-Fundamental Policies (All Funds).  Unless otherwise
stated, all investment objectives and policies are non-fundamental and may be
amended without shareholder approval.

     Percentage Investment Limitations (All Funds).  Unless otherwise stated,
percentage limitations in this prospectus apply at the time of investment.

     Portfolio Turnover (All Funds).  Each Fund may engage in frequent and
active trading of portfolio securities to achieve its investment objective. A
high portfolio turnover rate involves greater expenses to a Fund, including
brokerage commissions and other transaction costs, and is likely to generate
more taxable short-term gains for shareholders, which may have an adverse effect
on the performance of the Fund.

     The financial highlights table is intended to help you understand the
financial performance of the Funds' Class I Shares for the fiscal period ended
October 31, 1999. Certain information reflects financial results for a single
Fund share. The total returns in the table represent the rate an investor would
have earned or lost on an investment in the Funds (assuming reinvestment of all
dividends and distributions). Past performance does not guarantee future
results. This information has been audited by Ernst & Young LLP, independent
auditors, whose report, along with the Funds' financial statements, is included
in the Statement of Additional Information, which is available upon request.
Because the following Funds had not commenced operations prior to October 31,
1999, financial highlights are not presented for ING Tax Efficient Equity Value
Fund, ING Global Communications Fund, ING Internet Fund II, ING Balanced Fund,
ING Emerging Markets Equity Fund, ING Global Real Estate Fund and ING Quality of
Life Fund. In addition, because the following Funds had not commenced operations
of the Class I shares prior to October 31, 1999, financial highlights are not

                                   BOND FUNDS

 ING INTERMEDIATE BOND FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income consistent with the preservation of capital and
liquidity.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of debt securities which, at the time of investment, are rated
investment grade (for example, rated at least BBB by Standard & Poor's Rating
Group or Baa by Moody's Investor Services) or have an equivalent rating by a
nationally recognized statistical rating organization, or of comparable quality
if unrated. Although the Fund may invest a portion of its assets in high yield
(high risk) debt securities rated below investment grade, the Fund will seek to
maintain a minimum average portfolio quality rating of at least investment
grade. The dollar-weighted average maturity of the Fund will generally range
between three and ten years.

     The Fund may invest the remainder of its assets in: convertible securities
and preferred stocks; U.S. Government securities, securities of foreign
governments and supranational organizations, and high-quality money market
instruments that the Sub-Adviser believes are appropriate in light of the Fund's
investment objective; municipal bonds, notes and commercial paper; and debt
securities of foreign issuers. The Fund may purchase structured debt obligations
and may engage in dollar roll transactions and swap agreements. The Fund may
also sell securities short and may use options and futures contracts involving
securities, securities indices and interest rates. A portion of the Fund's
assets may be invested in mortgage-backed securities and asset-backed debt
securities.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, five step investment process which uses fundamental economic and
market research to identify bond market sectors and individual securities
expected to provide above-average returns. The five steps are:

     - First, the Sub-Adviser examines the sensitivity to interest rate
       movements of the portfolio and of the specific holdings of the portfolio
       to position the Fund in a way that attempts to maximize return while
       minimizing volatility.

     - Second, the Sub-Adviser reviews yields relative to maturity and risk of
       bonds to determine the risk/reward characteristics of bonds of different
       maturity classes.

     - Third, the Sub-Adviser identifies sectors that offer attractive value
       relative to other sectors.

     - Fourth, the Sub-Adviser selects securities within identified sectors that
       offer attractive value relative to other securities within their sectors.

     - Finally, the Sub-Adviser seeks trading opportunities to take advantage of
       market inefficiencies to purchase bonds at prices below their calculated
       value.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

       Interest Rate Risk -- In general, when interest rates go up, prices of
       fixed income securities go down. Securities with longer maturities are
       subject to greater fluctuations in value than securities with shorter
       maturities.

       Spread Risk -- The price of a fixed income security is generally
       determined by adding an interest rate spread to a benchmark interest
       rate, such as the U.S. Treasury rate. As the spread on a security widens
       (or increases), the price (or value) of the security falls.

       Default Risk -- An issuer of a security may default on its obligation to
       pay principal and/or interest.

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk -- An issuer of a security may prepay principal
       earlier than scheduled, which could force the Fund to reinvest in lower
       yielding securities.

       Extension Risk -- Slower than expected principal payments on a
       mortgage-backed or asset-backed security may extend such security's life,
       thereby

ING FUNDS TRUST                                                                3
- --------------------------------------------------------------------------------

       locking in a below-market interest rate, increasing the security's
       duration and reducing the value of the security.

     - Risk of High Yield Bonds.  High yield bonds carry particular market risks
       and may experience greater volatility in market value than investment
       grade bonds. Changes in interest rates, the market's perception of the
       issuers and the creditworthiness of the issuers may significantly affect
       the value of these bonds. Some of these securities may have a structure
       that makes their reaction to interest rates and other factors difficult
       to predict, causing their value to be highly volatile. Certain high yield
       bonds, such as zero coupon, deferred interest and payment-in-kind bonds,
       are issued at deep discounts and may experience greater volatility in
       market value. The secondary market for high yield bonds may be less
       liquid than the markets for higher quality securities and this may have
       an adverse effect on the market values of certain securities.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security, as well as credit risk with
       respect to the counterparty to the derivative instrument. The use of
       derivatives may reduce returns.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the Class I shares of
the ING Intermediate Bond Fund currently are not operational, there is no
performance information included in this Prospectus.

 ING HIGH YIELD BOND FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income and total return.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in a portfolio of high yield (high risk) bonds. High yield bonds are debt
securities that are not rated by a nationally recognized statistical rating
organization or are rated below investment grade (for example, rated below BBB
by Standard & Poor's Rating Group or Baa by Moody's Investor Services) or have
an equivalent rating by a nationally recognized statistical rating organization.
The Fund defines high yield bonds to include bank loans, payment-in-kind
securities, fixed, variable, floating rate and deferred interest debt
obligations, zero coupon bonds, mortgage-backed and asset-backed debt
obligations, structured debt obligations and convertible bonds, provided they
are unrated or rated below investment grade. In evaluating the quality of a
particular high yield bond for investment by the Fund, the Sub-Adviser does not
rely exclusively on ratings assigned by the nationally recognized statistical
rating organizations. The Sub-Adviser will utilize a security's credit rating as
simply one indication of an issuer's creditworthiness and will principally rely
upon its own analysis of any security. However, the Sub-Adviser does not have
restrictions on the rating level of the securities in the Fund's portfolio and
may purchase and hold securities in default. There are no restrictions on the
average maturity of the Fund or the maturity of any single investment.
Maturities may very widely depending on the Sub-Adviser's assessment of interest
rate trends and other economic or market factors.

     Any remaining assets may be invested in investment grade debt securities;
common and preferred stocks; U.S. Government securities and money market
instruments that the Sub-Adviser believes are appropriate in light of the Fund's
investment objectives; and debt securities of foreign issuers. The Fund may
purchase structured debt obligations and may engage in dollar roll transactions
and swap agreements. The Fund may also use options and futures contracts
involving securities, securities indices and interest rates.

     The Fund will not purchase any common stocks if, after such purchase, more
than 20% of the value of its total assets would be invested in common stocks.
The Fund will invest in common stocks in order to attempt to achieve either a
combination of its primary and secondary objectives, in which case the common
stocks will be dividend-paying, or to achieve its secondary objective, in which
the common stocks may not pay dividends.

     In choosing investments for the Fund, the Sub-Adviser combines extensive
company and industry research with relative value analysis to identify high
yield bonds expected to provide above-average returns. Relative value analysis
is intended to enhance returns by moving from overvalued to undervalued sectors
of the bond market. The Sub-Adviser's team approach to decision making includes
contributions from individual managers responsible for specific industry
sectors.

and Risks" section.

       Fund are subject to a number of risks, including, but not limited to:

       Interest Rate Risk -- In general, when interest rates go up, prices of
       fixed income securities go down. Securities with longer maturities are
       subject to greater fluctuations in value than securities with shorter
       maturities.

       Spread Risk -- The price of a fixed income security is generally
       determined by adding an interest rate spread to a benchmark interest
       rate, such as the U.S. Treasury rate. As the spread on a security widens
       (or increases), the price (or value) of the security falls.

       Default Risk -- An issuer of a security may default on its obligation to
       pay principal and/or interest.

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk -- An issuer of a security may prepay principal
       earlier than scheduled, which could force the Fund to reinvest in lower
       yielding securities.

       Extension Risk -- Slower than expected principal payments on a
       mortgage-backed or asset-backed security may extend such security's life,
       thereby locking in a below-market interest rate, increasing the
       security's duration and reducing the value of the security.

     - Risk of High Yield Bonds.  High yield bonds carry particular market risks
       and may experience greater volatility in market value than investment
       grade bonds. Changes in interest rates, the market's perception of the
       issuers and the creditworthiness of the issuers may significantly affect
       the value of these bonds. Some of these securities may have a structure
       that makes their reaction to interest rates and other factors difficult
       to predict, causing their value to be highly volatile. Certain high yield
       bonds, such as zero coupon, deferred interest and payment-in-kind bonds,
       are issued at deep discounts and may experience greater volatility in
       market value. The secondary market for high yield bonds may be less
       liquid than the markets for higher quality securities and this may have
       an adverse effect on the market values of certain securities.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security, as well as credit risk with
       respect to the counterparty to the derivative instrument. The use of
       derivatives may reduce returns.

     - Risks of Equity Investments.  Equity securities face market, issuer and
       other risks, and their values may go down, sometimes rapidly and
       unpredictably. Market risk is the risk that securities may decline in
       value due to factors affecting securities markets generally or particular
       industries. Issuer risk is the risk that the value of a security may
       decline for reasons relating to the issuer, such as changes in the
       financial condition of the issuer. Equities generally have higher
       volatility than debt securities.

 ING INTERNATIONAL BOND FUND

     Investment Objective.  The Fund seeks to provide investors with high total
return.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a non-diversified fund and invest at least 65% of its total
assets in a portfolio of fixed income securities of international issuers which,
at the time of investment, are rated investment grade (for example, rated at
least BBB by Standard & Poor's Rating Group or Baa by Moody's Investor Services)
or have an equivalent rating by a nationally recognized statistical rating
organization, or of comparable quality if unrated. This portion of the portfolio
will have investments in at least three different countries outside of the
United States. There are no restrictions on the average maturity of the Fund or
the maturity of any single investment. Maturities may vary widely depending on
the Sub-Advisers' assessment of interest rate trends and other economic or
market factors. Fixed income securities eligible for purchase by the Fund
consist of:

     - securities issued or guaranteed by foreign governments, their political
       subdivisions, agencies or instrumentalities;

     - corporate bonds and debentures rated investment grade (for example, rated
       at least BBB by Standard & Poor's Rating Group or Baa by Moody's Investor
       Services);

     - obligations of supranational entities;

     - repurchase agreements involving the foregoing securities;

     - loan participations;

     - short-term commercial paper of U.S. or foreign issuers rated in the
       highest two rating categories by a nationally recognized statistical
       rating organization; and

     - swap agreements.

- --------------------------------------------------------------------------------

     Any remaining assets of the Fund may be invested in securities denominated
in U.S. dollars or foreign currencies which are rated below investment grade
(for example, rated below BBB by Standard & Poor's Rating Group or Baa by
Moody's Investor Services) or have an equivalent rating by a nationally
recognized statistical rating organization, or of comparable quality if unrated;
U.S. Government securities; obligations of commercial banks, savings and loan
institutions, and U.S. and foreign branches of foreign banks that have total
assets of $500 million or more as shown on the last published financial
statements at the time of investment; mortgage-backed and asset-backed
securities rated within the three highest rating categories by a nationally
recognized statistical rating organization; receipts; and guaranteed investment
contracts. The Fund may also use options and futures contracts involving
securities, securities indices, interest rates and foreign currencies.

     In choosing investments for the Fund, the Sub-Advisers employ a highly
disciplined, four step investment process that seeks to identify bond market
sectors expected to provide high and sustainable real rates of return. The four
steps are:

     - First, the Sub-Adviser performs a comprehensive analysis of the relative
       value of bond issuances between countries and of currencies to determine
       the degree of representation of such countries and currencies in the
       Fund's portfolio;

     - Second, country allocations, as well as currency and maturity weightings,
       are reviewed by an independent committee within the Sub-Adviser;

     - Third, the Sub-Adviser selects investments within the selected countries
       and currencies based on comprehensive fundamental analysis; and

     - Finally, in-house traders use specially developed computer programs to
       efficiently purchase the targeted securities and currencies.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  You could lose money on an investment in the Fund. An
investment in the Fund is not a bank deposit and is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency. The
Fund may be affected by the following risks, among others:

     - Price Volatility.  The value of the Fund will decrease if the value of
       the Fund's underlying investments decrease.

     - Risks of Fixed Income Investments.  Fixed income securities held by the
       Fund are subject to a number of risks, including, but not limited to:

       Interest Rate Risk -- In general, when interest rates go up, prices of
       fixed income securities go down. Securities with longer maturities are
       subject to greater fluctuations in value than securities with shorter
       maturities.

       Spread Risk -- The price of a fixed income security is generally
       determined by adding an interest rate spread to a benchmark interest
       rate, such as the U.S. Treasury rate. As the spread on a security widens
       (or increases), the price (or value) of the security falls.

       Default Risk -- An issuer of a security may default on its obligation to
       pay principal and/or interest.

       Credit Risk -- An issuer of a security may have its credit rating
       downgraded, which would negatively impact the price of such security.
       Securities with lower credit ratings are generally subject to greater
       fluctuations in value than higher rated securities.

       Call or Prepayment Risk -- An issuer of a security may prepay principal
       earlier than scheduled, which could force the Fund to reinvest in lower
       yielding securities.

       Extension Risk -- Slower than expected principal payments on a
       mortgage-backed or asset-backed security may extend such security's life,
       thereby locking in a below-market interest rate, increasing the
       security's duration and reducing the value of the security.

     - Risks of Foreign Investing.  Foreign investments may be riskier than U.S.
       investments for many reasons, including changes in currency exchange
       rates, unstable political and economic conditions, possible security
       illiquidity, a lack of adequate company information, differences in the
       way securities markets operate, less secure foreign banks or securities
       depositories than those in the U.S., and foreign controls on investment.

     - Derivatives Risk.  Derivatives are subject to the risk of changes in the
       market price of the underlying security or currency, as well as credit
       risk with respect to the counterparty to the derivative instrument. The
       use of derivatives may reduce returns.

     - Lack of Diversification.  The Fund is classified as a non-diversified
       investment company, which means that, compared with other funds, the Fund
       may invest a greater percentage of its assets in a particular issuer. The
       investment of a large percentage of the Fund's assets in the securities
       of a small number of

- --------------------------------------------------------------------------------

       issuers may cause the Fund's share price to fluctuate more than that of a
       diversified investment company.

     Performance Summary.  Performance information is only shown for those Funds
which have had a full calendar year of operations. Since the Class I shares of
the ING International Bond Fund currently are not operational, there is no
performance information included in this Prospectus.

 ING MORTGAGE INCOME FUND

     Investment Objective.  The Fund seeks to provide investors with long-term
income consistent with preservation of capital.

     Principal Investment Strategies.  Under normal market conditions, the Fund
will operate as a diversified fund and invest at least 65% of its total assets
in mortgage-backed securities. Mortgage-backed securities are securities that
directly or indirectly represent a participation in, or are secured by and
payable from, mortgage loans secured by real property. There are currently three
basic types of mortgage-backed securities: (i) those issued or guaranteed by the
U.S. Government or one of its agencies or instrumentalities, such as Government
National Mortgage Association ("GNMA"), Federal National Mortgage Association
("FNMA") and Federal Home Loan Mortgage Corporation ("FHLMC"); (ii) those issued
by private issuers that represent an interest in or are collateralized by
mortgage-backed securities issued or guaranteed by the U.S. Government or one of
its agencies or instrumentalities; and (iii) those issued by private issuers
that represent an interest in or are collateralized by whole mortgage loans or
mortgage-backed securities without a government guarantee but usually having
some form of private credit enhancement. The Fund may invest in adjustable rate
and fixed rate mortgage securities. The Fund's investments will be rated, at the
time of investment, "A" or better by a nationally recognized statistical rating
organization, or of comparable quality if unrated.

     Any remaining assets of the Fund may be invested in other types of fixed
income securities, including, but not limited to, U.S. Government securities,
corporate bonds, notes and debentures, asset-backed securities and money market
instruments that the Sub-Adviser believes are appropriate in light of the Fund's
investment objective. The Fund may also use options and futures contracts
involving securities, securities indices and interest rates,

     There are no restrictions on the average maturity of the Fund or on the
maturity of any single instrument. Accordingly, the Fund may vary the proportion
of its holdings in long- and short-term debt securities in order to reflect its
assessment of prospective changes in interest rates even if such action may
adversely affect current income. For example, if in the opinion of the
Sub-Adviser, interest rates generally are expected to decline, the Fund may sell
its shorter term securities and purchase longer term securities in order to
benefit from greater expected relative price appreciation; however, the
securities sold may have a higher current yield than those being purchased. The
success of this strategy will depend on the Sub-Adviser's ability to forecast
changes in interest rates. Moreover, the Fund intends to manage its portfolio
actively by taking advantage of trading opportunities such as sales of portfolio
securities and purchases of higher yielding securities of similar quality due to
distortions in normal yield differentials.

EXAMPLES

     These Examples are intended to help you compare the cost of investing in
the Funds with the cost of investing in other mutual funds. Each Example assumes
that:

     - you invest $10,000 in Class I shares of each Fund for the time period
       indicated;

     - your investment has a 5% return each year;

     - the Fund's operating expenses remain the same, except for the expiration
       of the contractual expense limitations on October 31, 2000; and

     - you redeem all of your shares at the end of the time period indicated.
       The following expenses would be the same without redemption.

     Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

                            MANAGEMENT OF THE FUNDS

     The Investment Manager.  ING Mutual Funds Management Co. LLC (the
"Investment Manager") serves as each Fund's investment manager. The Investment
Manager is a wholly owned indirect subsidiary of ING Groep N.V. ("ING Group")
and is registered with the Securities and Exchange Commission. The Investment
Manager is located at 1475 Dunwoody Drive, West Chester, PA 19380. As of
December 31, 1999, the Investment Manager managed over $1.23 billion in assets.

     The Investment Manager supervises all aspects of each Fund's operations and
provides investment advisory services to the Funds. This includes engaging
sub-advisers, as well as monitoring and evaluating the management of the assets
of each such Fund by its sub-adviser. The Investment Manager has acted as an
investment adviser to mutual funds since 1998. Today, the Investment Manager
advises or manages 30 investment portfolios, including the Funds, encompassing a
broad range of investment objectives.

     Investment Manager Compensation.  The following table shows the aggregate
annual advisory fee to be paid by each Fund as a percentage of that Fund's
average daily net assets:

                             HOW TO PURCHASE SHARES

     The Funds offer a choice of five share classes, each with its own sales
load and expense structure, allowing you to invest in the way that best suits
your needs. Class I shares are offered in this Prospectus and may be purchased
only by (i) retirement plans affiliated with ING Group, and (ii) ING Group and
its affiliates for purposes of corporate cash management. Class A, Class B,
Class C and Class X shares are offered under separate prospectuses. The Class A,
Class B, Class C and Class X shares have different sales charges and other
expenses, which may affect performance. The Class X shares may be purchased only
by certain qualified investors (including, but not limited to, IRAs, Roth IRAs,
SEP IRAs, Simple IRAs and 403(b)(7) plans). Each share class represents an
ownership interest in the same investment portfolio.

     The Funds' shares are distributed by ING Funds Distributor, Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Funds' shares may be
sold by retail broker-dealers that are under common control with the Funds. As
of the date of this Prospectus, such broker-dealers are Compulife Investor
Services, Inc., IFG Network Securities, Inc., Locust Street Securities, Inc.,
Multi-Financial Securities Corporation, VESTAX Securities Corporation, ING
Barings Furman Selz LLC and ING Barings LLC.

     Orders for the purchase of Class I shares of the Funds will be executed at
the net asset value per share next determined after an order has been received.
The public offering price of each Fund is determined as of the close of regular
trading on the New York Stock Exchange (normally 4 p.m. Eastern time) on each
day the Exchange is open for business.

     The minimum initial investment in a Fund is $1,000. Any subsequent
investments must be at least $50. The Distributor may waive these minimums from
time to time. All initial investments should be accompanied by a completed
Account Application. An Account Application accompanies this Prospectus. All
funds received are invested in full and fractional shares of the appropriate
Fund. Certificates for shares are not issued. Contributions to qualified
retirement plans are subject to prevailing limits set by the Internal Revenue
Service. Your account will be charged an annual maintenance fee, but you will
not be charged more than one such fee with respect to multiple accounts of the
same plan type established under the same taxpayer identification number. The
Funds reserve the right to reject any purchase order. The Funds will accept
third party checks from qualified financial institutions, such as broker-dealers
and investment advisers that are registered with the Securities and Exchange
Commission, as well as insurance companies, banks, credit unions and thrift
companies. Personal third party checks and non-U.S. checks will not be accepted.
All initial investments may be made using any of the following methods:

                              HOW TO REDEEM SHARES

     You may redeem your shares, in whole or in part, on each day a Fund is
valued. Shares will be redeemed without charge at the net asset value next
determined after a redemption request in good order has been received by the
Funds. In the instance where you own more than one class of shares and the class
of shares being redeemed are not subject to a contingent deferred sales load,
those shares with
the highest Rule 12b-1 fee will be redeemed in full prior to any redemption of
shares with a lower Rule 12b-1 fee.
     When purchases are made by check in any Fund, redemption proceeds will be
made available immediately upon clearance of the purchase check, which may take
up to 15 calendar days. You may avoid this delay by investing through wire
transfers of federal funds.

     Once your shares are redeemed, the Funds will ordinarily send the proceeds
by check to you at the address of record on the next business day. To ensure
acceptance of your redemption request, it is important to follow the procedures
described below. If you purchased your shares through an Authorized Broker or
Investment Adviser, please contact them to inquire which redemption methods are
available to you. Under certain circumstances described below, a signature
guarantee may be required. You may redeem your shares using any of the following
methods:

     Your retirement plan administrator may establish separate policies and
procedures concerning the redemption of Fund shares and the completion of
documentation related to the redemption of shares. Please consult with your
retirement plan administrator to determine if any such separate policies and
procedures apply to you.

     The Funds reserve the right to redeem in kind. That is, the Funds may honor
redemption requests with readily marketable portfolio securities instead of cash
if during any 90-day period redemptions exceed the lesser of $250,000 or 1% of
the net assets of the redeeming Fund at the beginning of such period. You may
incur transaction costs associated with converting these securities to cash.

     Due to the high costs of maintaining small accounts, the Funds may ask that
you increase your account balance if (1) the value of your account falls below
$500 for three consecutive months as a result of redemptions or exchanges, and
(2) your account has been in existence for at least one year and you have not
made any additional purchases in the account within the preceding six calendar
months. If the account balance remains below the minimum requirement for 60 days
after you are notified, the Funds may close your account and send you the
redemption proceeds.

     Signature Guarantees.  A signature guarantee is designed to protect the
investor, the Funds and their agents by verifying the signature of certain
investors seeking to redeem, transfer, or exchange shares of the Funds.
Signature guarantees are required for:

     - redemptions by mail in excess of $50,000;

     - redemptions by mail if the proceeds are to be paid to someone other than
       the name(s) in which the account is registered;

     - redemptions requesting proceeds to be sent to a new address or an address
       that has been changed within the past 15 days;

     - requests to transfer the registration of shares to another owner; or

     - redemptions or exchanges of shares previously reported as lost/abandoned
       property, whether or not the redemption amount is under $50,000 or the
       proceeds are to be sent to the address of record.

     The foregoing requirements may be waived or modified upon notice to
shareholders.

     Acceptable guarantors include banks, broker-dealers, credit unions,
national securities exchanges, savings associations and any other organization,
provided that such institution or organization qualifies as an "eligible
guarantor institution" as that term is defined in rules adopted by the
Securities and Exchange Commission. For information regarding whether a
particular institution or organization qualifies as an "eligible guarantor
institution," contact the Funds at 1-877-INFO-ING.

                               EXCHANGE PRIVILEGE

     Class I shares of a Fund may be exchanged, based on the per share net asset
values, for Class I shares of any other Fund. Your exchange will be processed at
the next determined net asset value after the Funds receive your request. A new
account opened by exchange must be established with the same name(s), address
and social security number as the existing account.

     Your retirement plan administrator may establish separate policies and
procedures concerning the exchange of Fund shares and the completion of
documentation related to
the exchange of shares. Please consult with your retirement plan administrator
to determine if any such separate policies and procedures apply to you.

                               PRICING OF SHARES

     Each of the Funds prices its shares based on its net asset value. The Funds
value portfolio securities for which market quotations are readily available at
market price. These Funds value 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 Funds may value the security at its fair value as determined
in good faith by or under the supervision of the Board of Trustees. The effect
of using fair value pricing is that a Fund's net asset value will be subject to
the judgment of the Board of Trustees or its designee instead of being
determined by the market. Because some of the Funds may invest in securities
that are primarily listed on foreign exchanges, the value of those Funds' shares
may change on days when you will not be able to purchase or redeem shares.

     Each Fund determines the net asset value of its shares as of the close of
the NYSE (normally 4:00 p.m., Eastern time) on each day the NYSE is open for
business. The price at which a purchase or redemption is effected is based on
the next calculation of a Fund's net asset value after the order is placed.

- --------------------------------------------------------------------------------

                          DIVIDENDS AND DISTRIBUTIONS

     Each Fund intends to distribute to its shareholders substantially all of
its investment company taxable income (which includes dividends and interest and
the excess, if any, of net short-term capital gains over net long-term capital
losses). Each of the Funds will declare dividends daily and pay dividends
monthly. In addition, each Fund intends to distribute, at least annually,
substantially all of its net capital gains (the excess of net long-term capital
gains over net short-term capital losses). In determining amounts of capital
gains to be distributed, any capital loss carryovers from prior years will be
applied against capital gains.

     Dividends and distributions will be reinvested in additional shares of a
Fund at net asset value. If you redeem all or a portion of Fund shares prior to
a dividend payment date, you will be entitled on the next dividend payment date
to all dividends declared but unpaid on those shares at the time of their
redemption.

                                     TAXES

     Each Fund is treated as a separate entity for federal income tax purposes.
Each Fund intends to qualify as a regulated investment company by satisfying the
requirements under Subchapter M of the Internal Revenue Code of 1986 (the
"Code"), including requirements with respect to diversification of assets,
distribution of income and sources of income. By so qualifying, each Fund
generally will not be subject to federal income tax to the extent that it
distributes investment company taxable income and net realized capital gains in
the manner required under the Code.

     Investment income received by a Fund from sources within foreign countries
may be subject to foreign income taxes withheld at the source. Such withholding
taxes may be reduced or eliminated under the terms of applicable United States
income tax treaties, and the Funds intend to undertake any procedural steps
required to claim the benefits of such treaties.

     Under the backup withholding rules of the Code, you may be subject to 31%
withholding of federal income tax on ordinary income dividends paid by a Fund.
In order to avoid this backup withholding, you must provide the Funds with a
correct taxpayer identification number or certify that you are otherwise exempt
from or not subject to backup withholding.

     Special tax treatment, including a penalty on certain pre-retirement
distributions, is granted to accounts maintained as qualified retirement plans.
The foregoing discussion is intended for shareholders that are exempt from
federal income taxes. You should consult your own tax advisor as to the federal,
state and local tax consequences of ownership of shares of the Funds in your
particular circumstances.

                  MORE INFORMATION ABOUT STRATEGIES AND RISKS

     A Fund's risk profile is largely a factor of the principal securities in
which it invests and investment techniques that it uses. The following pages
discuss the risks associated with certain of the types of securities in which
the Funds may invest and certain of the investment practices that the Funds may
use. For more information about these and other types of securities and
investment techniques used by the Funds, see the Statement of Additional
Information. Unless indicated otherwise, the following descriptions apply to all
Funds.

     Many of the investment techniques and strategies discussed in this
Prospectus and in the Statement of Additional Information are discretionary,
which means that the Investment Manager or Sub-Adviser can decide whether to use
them or not. The Investment Manager or Sub-Adviser may also use investment
techniques or make investments in securities that are not a part of the Fund's
principal investment strategy.

     Temporary Defensive Strategies (All Funds).  When the Investment Manager or
Sub-Adviser to a Fund anticipates unusual market or other conditions, the Fund
may temporarily depart from its principal investment strategies. Under such
circumstances, up to 100% of the Fund's assets may be invested in investment
grade fixed income securities (for example, rated at least BBB by Standard &
Poor's Rating Group or Baa by Moody's Investor Services), money market
securities, certificates of deposit, bankers' acceptances, commercial paper or
in any other securities which in either the Investment Manager's or
Sub-Adviser's opinion are more conservative than the types of securities in
which the Fund typically invests. To the extent a Fund is engaged in temporary
defensive investments, it will not be pursuing its investment objective.

     Investments in Foreign Securities (All Funds except ING Mortgage Income
Fund).  There are certain risks in owning foreign securities, including those
resulting from: fluctuations in currency exchange rates; devaluation of
<PAGE>   255

- --------------------------------------------------------------------------------

currencies; political or economic developments and the possible imposition of
currency exchange blockages or other foreign governmental laws or restrictions;
reduced availability of public information concerning issuers; accounting,
auditing and financial reporting standards or other regulatory practices and
requirements that are not uniform when compared to those applicable to domestic
companies; settlement and clearance procedures in some countries that may not be
reliable and can result in delays in settlement; higher transaction and custody
expenses than for domestic securities; and limitations on foreign ownership of
equity securities. Also, securities of many foreign companies may be less liquid
and the prices more volatile than those of domestic companies. With certain
foreign countries, there is the possibility of expropriation, nationalization,
confiscatory taxation and limitations on the use or removal of funds or other
assets of the Funds, including the withholding of dividends.

     Each Fund that invests in foreign securities may enter in to foreign
currency transactions either on a spot or cash basis at prevailing rates or
through forward foreign currency exchange contracts in order to have the
necessary currencies to settle transactions or to help protect the Fund against
adverse changes in foreign currency exchange rates. Such efforts could limit
potential gains that might result from a relative increase in the value of such
currencies, and might, in certain cases, result in losses to the Fund.

     Emerging Market Investments (ING High Yield Bond Fund, ING Intermediate
Bond Fund and ING International Bond Fund).  Because of less developed markets
and economies and, in some countries, less mature governments and governmental
institutions, the risks of investing in foreign securities can be intensified in
the case of investments in issuers domiciled or doing substantial business in
emerging market countries. These risks include: high concentration of market
capitalization and trading volume in a small number of issuers representing a
limited number of industries, as well as a high concentration of investors and
financial intermediaries; political and social uncertainties; over-dependence on
exports, especially with respect to primary commodities, making these economies
vulnerable to changes in commodity prices; overburdened infrastructure and
obsolete financial systems; environmental problems; less well developed legal
systems; and less reliable custodial services and settlement practices.

     High Yield Securities (ING High Yield Bond Fund, ING Intermediate Bond Fund
and ING International Bond Fund). Investments in high yield securities generally
provide greater income and increased opportunity for capital appreciation than
investments in higher quality debt securities, but they also typically entail
greater potential price volatility and principal and income risk. High yield
securities are not considered investment grade, and are regarded as
predominantly speculative with respect to the issuing company's continuing
ability to meet principal and interest payments. The prices of high yield
securities have been found to be less sensitive to interest rate changes than
higher-rated investments, but more sensitive to adverse economic downturns or
individual corporate developments. High yield securities structured as
zero-coupon or payment-in-kind securities tend to be more volatile. The
secondary market in which high yield securities are traded is generally less
liquid than the market for higher-grade bonds. At times of less liquidity, it
may be more difficult to value high yield securities.

     Corporate and Municipal Debt Securities (All Funds). Corporate debt
securities are subject to the risk of the issuer's inability to meet principal
and interest payments on the obligation and may also be subject to price
volatility due to such factors as interest rate sensitivity, market perception
of the credit-worthiness of the issuer and general market liquidity. When
interest rates decline, the value of the debt securities can be expected to
rise, and when interest rates rise, the value of those securities can be
expected to decline. Debt securities with longer maturities tend to be more
sensitive to interest rate movements than those with shorter maturities.

     Initial Public Offerings (All Funds).  A significant portion of a Fund's
return may be attributable to its investment in initial public offerings. When a
Fund's asset base is small, the impact of such investments on a Fund's return
will be magnified. As the Fund's assets grow, it is probable that the effect of
the Fund's investment in initial public offerings on the Fund's total return
will decline.

     U.S. Government Securities (All Funds).  Some U.S. Government agency
securities may be subject to varying degrees of credit risk, and all U.S.
Government securities may be subject to price declines in the securities due to
changing interest rates.

     Convertible Securities (All Funds).  The price of a convertible security
will normally fluctuate in some proportion to changes in the price of the
underlying equity security, and as such is subject to risks relating to the
activities of the issuer and general market and economic conditions. The income
component of convertible securities causes fluctuations based upon changes in
interest rates and the credit quality of the issuer. Convertible securities are
often lower rated securities. A Fund may be required to redeem or convert a
convertible security before the holder would otherwise choose.

     Other Investment Companies (All Funds).  Each Fund may invest up to 10% of
its assets in other unaffiliated investment companies. There is no limit with
regard to investments in affiliated investment companies. When a Fund invests in
other investment companies, you indirectly pay a proportionate share of the
expenses of that other investment company (including management fees,
administration fees, and custodial fees) in addition to the expenses of the
Fund.
<PAGE>   256
ING FUNDS TRUST                                                               15
- --------------------------------------------------------------------------------

     Restricted and Illiquid Securities (All Funds).  Each Fund may invest up to
15% of its net assets in restricted and illiquid securities. If a security is
illiquid, the Fund might be unable to sell the security at a time when the
sub-adviser might wish to sell, and the security could have the effect of
decreasing the overall level of the Fund's liquidity. Further, the lack of an
established secondary market may make it more difficult to value illiquid
securities, which could vary from the amount the Fund could realize upon
disposition. Restricted securities, i.e., securities subject to legal or
contractual restrictions on resale, may be illiquid. However, some restricted
securities may be treated as liquid, although they may be less liquid than
registered securities traded on established secondary markets.

     Mortgage-Related Securities (All Funds).  Although mortgage loans
underlying a mortgage-backed security may have maturities of up to 30 years, the
actual average life of a mortgage-backed security typically will be
substantially less because the mortgages will be subject to normal principal
amortization, and may be prepaid prior to maturity. Like other fixed income
securities, when interest rates rise, the value of a mortgage-backed security
generally will decline; however, when interest rates are declining, the value of
mortgage-backed securities with prepayment features may not increase as much as
other fixed income securities. The rate of prepayments on underlying mortgages
will affect the price and volatility of a mortgage-related security, and may
have the effect of shortening or extending the effective maturity of the
security beyond what was anticipated at the time of the purchase. Unanticipated
rates of prepayment on underlying mortgages can be expected to increase the
volatility of such securities. In addition, the value of these securities may
fluctuate in response to the market's perception of the creditworthiness of the
issuers of mortgage-related securities owned by a Fund. Additionally, although
mortgages and mortgage-related securities are generally supported by some form
of government or private guarantee and/or insurance, there is no assurance that
private guarantors or insurers will be able to meet their obligations.

     Asset-Backed Securities (All Funds).  Asset-backed securities involve
certain risks that are not posed by mortgage-related securities, resulting
mainly from the fact that asset-backed securities often do not contain the
benefit of a complete security interest in the related collateral. The risks
associated with asset-backed securities may be reduced by the addition of credit
enhancements such as a bank letter of credit or a third-party guarantee.

     Derivatives (All Funds).  Generally, derivatives can be characterized as
financial instruments whose performance is derived, at least in part, from the
performance of an underlying asset or assets. Some derivatives are sophisticated
instruments that typically involve a small investment of cash relative to the
magnitude of risks assumed. These may include swap agreements, options, forwards
and futures. Derivative securities are subject to market risk, which could be
significant for those that have a leveraging effect. Many of the Funds do not
invest in these types of derivatives, so please check the description of the
Fund's policies found in the Statement of Additional Information. Derivatives
are also subject to credit risks related to the counterparty's ability to
perform, and any deterioration in the counterparty's creditworthiness could
adversely affect the instrument. A risk of using derivatives is that the adviser
might imperfectly judge the market's direction. For instance, if a derivative is
used as a hedge to offset investment risk in another security, the hedge might
not correlate to the market's movements and may have unexpected or undesired
results, such as a loss or a reduction in gains.

     Dollar Roll Transactions (All Funds).  The Funds may enter into dollar roll
transactions wherein the Fund sells fixed income securities, typically
mortgage-backed securities, and makes a commitment to purchase similar, but not
identical, securities at a later date from the same party. Like a forward
commitment, during the roll period no payment is made for the securities
purchased and no interest or principal payments on the security accrue to the
purchaser, but a Fund assumes the risk of ownership. A Fund is compensated for
entering into dollar roll transactions by the difference between the current
sales price and the forward price for the future purchase, as well as by the
interest earned on the cash proceeds of the initial sale. Like other when-issued
securities or firm commitment agreements, dollar roll transactions involve the
risk that the market value of the securities sold by the Funds may decline below
the price at which a Fund is committed to purchase similar securities. In the
event the buyer of securities under a dollar roll transaction becomes insolvent,
the Funds' use of the proceeds of the transaction may be restricted pending a
determination by the other party, or its trustee or receiver, whether to enforce
the Funds' obligation to repurchase the securities.

     Repurchase Agreements (All Funds).  Each Fund may enter into repurchase
agreements, which involve the purchase by a Fund of a security that the seller
has agreed to buy back. If the seller defaults and the collateral value
declines, the Fund might incur a loss. If the seller declares bankruptcy, the
Fund may not be able to sell the collateral at the desired time.

     Lending Portfolio Securities (All Funds).  In order to generate additional
income, each Fund may lend portfolio securities in an amount up to 33 1/3% of
its total assets to broker-dealers, major banks, or other recognized domestic
institutional borrowers of securities. As with other extensions of credit, there
are risks of delay in recovery or even loss of rights in the collateral should
the borrower default or fail financially.

     Borrowing (All Funds).  Each Fund may borrow for certain types of temporary
or emergency purposes subject to certain limits. Borrowing may exaggerate the
effect of any
<PAGE>   257
 16                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

increase or decrease in the value of portfolio securities or the net asset value
of a Fund, and money borrowed will be subject to interest costs. Interest costs
on borrowings may fluctuate with changing market rates of interest and may
partially offset or exceed the return earned on borrowed funds. Under adverse
market conditions, a Fund might have to sell portfolio securities to meet
interest or principal payments at a time when fundamental investment
considerations would not favor such sales.

     Reverse Repurchase Agreements (All Funds).  A reverse repurchase agreement
involves the sale of a security, with an agreement to repurchase the same
securities at an agreed upon price and date. Whether such a transaction produces
a gain for a Fund depends upon the costs of the agreements and the income and
gains of the securities purchased with the proceeds received from the sale of
the security. If the income and gains on the securities purchased fail to exceed
the costs, net asset value will decline faster than otherwise would be the case.
Reverse repurchase agreements, as leveraging techniques, may increase a Fund's
yield; however, such transactions may result in a shareholder's loss of
principal.

     Short Sales (ING Intermediate Bond Fund and ING High Yield Bond Fund).  A
"short sale" is the sale by a Fund of a security which has been borrowed from a
third party on the expectation that the market price will drop. If the price of
the security rises, the Fund may have to cover its short position at a higher
price than the short sale price, resulting in a loss.

     Investments in Small- and Mid-Capitalization Companies (ING High Yield Bond
Fund and ING Intermediate Bond Fund).  Certain Funds may invest in small and mid
capitalization companies. Investments in mid-and small-capitalization companies
involve greater risk than is customarily associated with larger, more
established companies due to the greater business risks of small size, limited
markets and financial resources, narrow product lines and the frequent lack of
depth of management. The securities of smaller companies are often traded
over-the-counter and may not be traded in volumes typical on a national
securities exchange. Consequently, the securities of smaller companies may have
limited market stability and may be subject to more abrupt or erratic market
movements than securities of larger, more established growth companies or the
market averages in general.

     Non-diversified Investment Companies (ING International Bond
Fund).  Certain Funds are classified as non-diversified investment companies
under the 1940 Act, which means that each Fund is not limited by the 1940 Act in
the proportion of its assets that it may invest in the obligations of a single
issuer. The investment of a large percentage of a Fund's assets in the
securities of a small number of issuers may cause that Fund's share price to
fluctuate more than that of a diversified investment company.

     Fundamental and Non-Fundamental Policies (All Funds).  Unless otherwise
stated, all investment objectives and policies are non-fundamental and may be
amended without shareholder approval.

     Percentage Investment Limitations (All Funds).  Unless otherwise stated,
percentage limitations in this prospectus apply at the time of investment.

     Portfolio Turnover (All Funds).  Each Fund may engage in frequent and
active trading of portfolio securities to achieve its investment objective. A
high portfolio turnover rate involves greater expenses to a Fund, including
brokerage commissions and other transaction costs, and is likely to generate
more taxable short-term gains for shareholders, which may have an adverse effect
on the performance of the Fund.

     The financial highlights table is intended to help you understand the
financial performance of the Funds' Class I Shares for the fiscal period ended
October 31, 1999. Certain information reflects financial results for a single
Fund share. The total returns in the table represent the rate an investor would
have earned or lost on an investment in the Funds (assuming reinvestment of all
dividends and distributions). Past performance does not guarantee future
results. This information has been audited by Ernst & Young LLP, independent
auditors, whose report, along with the Funds' financial statements, is included
in the Statement of Additional Information, which is available upon request.
Because the following Fund had not commenced operations prior to October 31,
1999, financial highlights are not presented for ING Mortgage Income Fund. In
addition, because the following Funds had not commenced operations of the Class
I shares prior to October 31, 1999, financial highlights are not presented for

- --------------------------------------------------------------------------------

                               MONEY MARKET FUNDS

 ING MONEY MARKET FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income as is consistent with the preservation of capital and
liquidity and the maintenance of a stable $1.00 net asset value per share.

     Principal Investment Strategies.  The Fund will operate as a diversified
fund and invest in a portfolio of high-quality, U.S. dollar denominated
short-term debt obligations which are determined by the Sub-Adviser to present
minimal credit risks.

     Portfolio investments of the Fund are valued based on the amortized cost
valuation method pursuant to Rule 2a-7 under the Investment Company Act of 1940.
Obligations in which the Fund invests generally have remaining maturities of 397
days or less, although upon satisfying certain conditions of Rule 2a-7, the Fund
may, to the extent otherwise permissible, invest in instruments subject to
repurchase agreements and certain variable and floating rate obligations that
bear longer final maturities. The dollar-weighted average portfolio maturity of
the Fund will not exceed 90 days.

     The Fund will invest in obligations permitted to be purchased under Rule
2a-7 including, but not limited to, (i) U.S. Government securities and
obligations of its agencies or instrumentalities; (ii) commercial paper,
mortgage-backed and asset-backed securities, guaranteed investment contracts,
loan participation interests, medium-term notes, and other promissory notes,
including floating and variable rate obligations; and (iii) the following
domestic, Yankeedollar and Eurodollar obligations: certificates of deposit, time
deposits, bankers acceptances, commercial paper, and other promissory notes,
including floating and variable rate obligations issued by U.S. or foreign bank
holding companies and their bank subsidiaries, branches and agencies. The Fund
may invest more than 25% of its total assets in instruments issued by domestic
banks.

     The Fund may purchase securities on a "when-issued" basis and purchase or
sell them on a "forward commitment" basis. The Fund may also invest in variable
rate master demand obligations, which are unsecured demand notes that permit the
underlying indebtedness to vary, and provide for periodic adjustments in the
interest rate. The Fund may enter into repurchase agreements.

     In choosing investments for the Fund, the Sub-Adviser employs a highly
disciplined, four step investment process designed to ensure preservation of
capital and liquidity, as well as adherence to regulatory requirements. The four
steps are:

     - First, a formal list of high-quality issuers is actively maintained;

     - Second, securities of issuers on the approved list which meet maturity
       guidelines and are rated "first tier" (that is, they are given the
       highest short-term rating by at least two nationally recognized
       statistical rating organizations, or by a single rating organization if a
       security is rated only by that organization, or are determined to be of
       comparable quality by the Sub-Adviser pursuant to guidelines approved by
       the Fund's Board of Trustees) are selected for investment;

     - Third, diversification is continuously monitored to ensure that
       regulatory limits are not exceeded; and

     - Finally, portfolio maturity decisions are made based upon expected cash
       flows, income opportunities available in the market and expectations of
       future interest rates.

     A more detailed discussion of the Principal Investment Strategies is
available in the Statement of Additional Information under "Investment Policies
and Risks" section.

     Principal Risks.  An investment in the Fund is not a bank deposit and is
not insured or guaranteed by the Federal Deposit Insurance Corporation or any
other government agency. Although the Fund seeks to preserve the value of your
investment at $1.00 per share, it is possible to lose money by investing in the
Fund. The Fund's yield will vary and the Fund may not achieve as high a level of
current income as other funds that do not limit their investments to the
high-quality securities in which the Fund invests.

     Performance Summary.  The following bar chart and tables depict the Fund's
annual returns and long-term performance. The Fund's past performance is not an
indication of its future performance. The returns shown are for the Fund's Class
A shares which are not offered in this prospectus. The Class I shares would have
substantially similar annual returns because the Class I shares are invested in
the same portfolio of securities and the annual returns would differ only to the
extent that Class I shares and Class A shares do not have the same expenses.

     The Fund's seven-day yield as of December 31, 1999 for the Class I shares
was 5.51%. The "seven-day yield" is an annualized figure -- the amount you would
earn if you kept your investment in the Fund and the Fund continued to earn the
same net interest income throughout the year.

     The Fund's seven-day effective yield as of December 31, 1999 for the Class
I shares was 5.66%. The "seven-day effective yield" (also an annualized figure)
assumes that dividends are reinvested and compounded.

 ING U.S. TREASURY MONEY MARKET FUND

     Investment Objective.  The Fund seeks to provide investors with a high
level of current income as is consistent with liquidity, maximum safety of
principal and the maintenance of a stable $1.00 net asset value per share.

     Principal Investment Strategies.  The Fund will operate as a diversified
fund and invest in direct short-term obligations of the United States Treasury,
which are backed by the full faith and credit of the United States Government.
The Fund may also invest in repurchase agreements which are fully collateralized
by U.S. Treasury securities. The Fund may purchase U.S. Treasury securities on a
"when-issued" basis and purchase or sell them on a "forward commitment" basis.

     Portfolio investments of the Fund are valued based on the amortized cost
valuation method pursuant to Rule 2a-7 under the Investment Company Act of 1940.
Obligations in which the Fund invests generally have remaining maturities of 397
days or less, although upon satisfying certain conditions of Rule 2a-7, the Fund
may, to the extent otherwise permissible, invest in instruments subject to
repurchase agreements and certain variable and floating rate obligations that
bear longer final maturities. The dollar-weighted average portfolio maturity of
the Fund will not exceed 90 days.

     Maturity decisions are made by the Sub-Adviser based upon liquidity
requirements, yield curve analysis and market expectations of future interest
rates.

available in the Statement of Additional Information under "Investment Policies

(1) Other expenses for the ING U.S. Treasury Money Market Fund are based on
    estimated amounts for the current fiscal year.

(2) The Investment Manager has entered into expense limitation contracts with
    each of the Funds, under which it will limit expenses of each Fund,
    excluding interest, taxes, brokerage and extraordinary expenses through
    October 31, 2000. The expense limit for each such Fund is shown as "Net
    Expenses". Fee waiver and/or reimbursements by the Investment Manager may
    vary in order to achieve such contractually obligated "Net Expenses".

EXAMPLES

     These Examples are intended to help you compare the cost of investing in
the Funds with the cost of investing in other mutual funds. Each Example assumes
that:

     - you invest $10,000 in Class I shares of each Fund for the time period
       indicated;

     - your investment has a 5% return each year;

     - the Fund's operating expenses remain the same, except for the expiration
       of the contractual expense limitations on October 31, 2000; and

     - you redeem all of your shares at the end of the time period indicated.
       The following expenses would be the same without redemption.

     Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

                             HOW TO PURCHASE SHARES

     The Funds offer a choice of five share classes, each with its own sales
load and expense structure, allowing you to invest in the way that best suits
your needs. Class I shares are offered in this Prospectus and may be purchased
only by (i) retirement plans affiliated with ING Group, and (ii) ING Group and
its affiliates for purposes of corporate cash management. Class A, Class B,
Class C and Class X shares are offered under separate prospectuses. The Class A,
Class B, Class C and Class X shares have different sales charges and other
expenses, which may affect performance. The Class X shares may be purchased only
by certain qualified investors (including, but not limited to, IRAs, Roth IRAs,
SEP IRAs, Simple IRAs and 403(b)(7) plans). Each share class represents an
ownership interest in the same investment portfolio.

     The Funds' shares are distributed by ING Funds Distributor, Inc. (the
"Distributor"), an affiliate of the Investment Manager. The Funds' shares may be
sold by retail broker-dealers that are under common control with the Funds. As
of the date of this Prospectus, such broker-dealers are Compulife Investor
Services, Inc., IFG Network Securities, Inc., Locust Street Securities, Inc.,
Multi-Financial Securities Corporation, VESTAX Securities Corporation, ING
Barings Furman Selz LLC and ING Barings LLC.

     Orders for the purchase of Class I shares of the Funds will be executed at
the net asset value per share next determined after an order has been received.
The public offering price of each Fund is determined as of the close of regular
trading on the New York Stock Exchange (normally 4 p.m. Eastern time) on each
day the Exchange and the Federal Reserve Bank are open for business.

     Notwithstanding the foregoing, a purchase order for shares of a Fund within
this Prospectus must generally be received by a specified "cut-off " time to be
executed on the same day at the price per share next determined, provided that
the Funds' custodian receives federal funds or other immediately available funds
by 4 p.m. Eastern time. The cut-off time applicable to the ING Money Market Fund
is 3:00 p.m. Eastern time and the cut-off time applicable to the ING U.S.
Treasury Money Market Fund is 12 noon Eastern time.

     The minimum initial investment in a Fund is $1,000. Any subsequent

     Your retirement plan administrator may establish separate policies and
procedures concerning the purchase of Fund shares and the completion of
documentation related to the purchase of shares. Please consult with your
retirement plan administrator to determine if any such separate policies and
procedures apply to you.

                              HOW TO REDEEM SHARES

     You may redeem your shares, in whole or in part, on each day a Fund is
valued. Shares will be redeemed without charge at the net asset value next
determined after a redemption request in good order has been received by the
Funds. In the instance where you own more than one class of shares and the class
of shares being redeemed are not subject to a contingent deferred sales load,
those shares with

the highest Rule 12b-1 fee will be redeemed in full prior to any redemption of
shares with a lower Rule 12b-1 fee.

     When purchases are made by check in any Fund, redemption proceeds will be
made available immediately upon clearance of the purchase check, which may take
up to 15 calendar days. You may avoid this delay by investing through wire
transfers of federal funds.

                                 from IRAs or other retirement plans. Please call the
                                 Funds at 1-877-INFO-ING for instructions.
  Through an Authorized          You may redeem your shares by contacting your authorized
  Broker or Investment           broker or investment advisor and instructing him or her
  Adviser                        to redeem your shares. Your representative will then
                                 contact the Funds and place a redemption trade on your
                                 behalf. These organizations may impose certain
                                 restrictions on redemptions and may charge you a fee for
                                 the transaction.
</TABLE>

     Your retirement plan administrator may establish separate policies and
procedures concerning the redemption of Fund shares and the completion of
documentation related to the redemption of shares. Please consult with your
retirement plan administrator to determine if any such separate policies and
procedures apply to you.

     The Funds reserve the right to redeem in kind. That is, the Funds may honor
redemption requests with readily marketable portfolio securities instead of cash
if during any 90-day period redemptions exceed the lesser of $250,000 or 1% of
the net assets of the redeeming Fund at the beginning of such period. You may
incur transaction costs associated with converting these securities to cash.

     Due to the high costs of maintaining small accounts, the Funds may ask that
you increase your account balance if (1) the value of your account falls below
$500 for three consecutive months as a result of redemptions or exchanges, and
(2) your account has been in existence for at least one year and you have not
made any additional purchases in the account within the preceding six calendar
months. If the account balance remains below the minimum requirement for 60 days
after you are notified, the Funds may close your account and send you the
redemption proceeds.

     Signature Guarantees.  A signature guarantee is designed to protect the
investor, the Funds and their agents by verifying the signature of certain
investors seeking to redeem, transfer, or exchange shares of the Funds.
Signature guarantees are required for:

     - redemptions by mail in excess of $50,000;

     - redemptions by mail if the proceeds are to be paid to someone other than
       the name(s) in which the account is registered;

     - redemptions requesting proceeds to be sent to a new address or an address
       that has been changed within the past 15 days;

     - requests to transfer the registration of shares to another owner; or

- --------------------------------------------------------------------------------

     - redemptions or exchanges of shares previously reported as lost/abandoned
       property, whether or not the redemption amount is under $50,000 or the
       proceeds are to be sent to the address of record.

     The foregoing requirements may be waived or modified upon notice to
shareholders.

     Acceptable guarantors include banks, broker-dealers,

credit unions, national securities exchanges, savings associations and any other
organization, provided that such institution or organization qualifies as an
"eligible guarantor institution" as that term is defined in rules adopted by the
Securities and Exchange Commission. For information regarding whether a
particular institution or organization qualifies as an "eligible guarantor
institution," contact the Funds at 1-877-INFO-ING.

                               EXCHANGE PRIVILEGE

     Class I shares of a Fund may be exchanged, based on the per share net asset
values, for Class I shares of any other Fund. Your exchange will be processed at
the next determined net asset value after the Funds receive your request. A new
account opened by exchange must be established with the same name(s), address
and social security number as the existing account.

     You may only exchange shares into a Fund which is authorized for sale in
your state of residence. The Funds may limit each account to eight exchanges per
calendar year. The Funds may change or discontinue the exchange privilege after
giving you 60 days' prior notice. An exchange of shares is a taxable event on
which you may realize a gain or loss. You may exchange shares using any of the
following methods:

ING FUNDS TRUST                                                                9
- --------------------------------------------------------------------------------

                               PRICING OF SHARES

     Each of the Funds prices its shares based on its net asset value. The Funds
use the amortized cost method to value its portfolio securities and seek to
maintain a constant net asset value of $1.00 per share, although there may be
circumstances under which this goal cannot be achieved. The amortized cost
method involves valuing a security at its cost and amortizing any discount or
premium over the period until maturity, regardless of the impact of fluctuating
interest rates on the market value of the security. Although the Board of
Trustees has established procedures designed to stabilize, to the extent
reasonably possible, the share price of the Funds, there can be no assurance
that each Fund's net asset value can be maintained at $1.00 per share.

     Each Fund determines the net asset value of its shares as of the close of
the NYSE (normally 4:00 p.m., Eastern time) on each day the NYSE and the Federal
Reserve Bank are open for business. The price at which a purchase or redemption
is effected is based on the next calculation of a Fund's net asset value after
the order is placed.

                          DIVIDENDS AND DISTRIBUTIONS

     Each Fund intends to distribute to its shareholders substantially all of
its investment company taxable income (which includes dividends and interest and
the excess, if any, of net short-term capital gains over net long-term capital
losses). Each of the Funds will declare dividends daily and pay dividends
monthly. In addition, each Fund intends to distribute, at least annually,
substantially all of its net capital gains (the excess of net long-term capital
gains over net short-term capital losses). In determining amounts of capital
gains to be distributed, any capital loss carryovers from prior years will be
applied against capital gains.

     Dividends and distributions will be reinvested in additional shares of a
Fund at net asset value. If you redeem all or a portion of Fund shares prior to
a dividend payment date, you will be entitled on the next dividend payment date
to all dividends declared but unpaid on those shares at the time of their
redemption.

                                     TAXES

     Each Fund is treated as a separate entity for federal income tax purposes.
Each Fund intends to qualify as a regulated investment company by satisfying the
requirements under Subchapter M of the Internal Revenue Code of 1986 (the
"Code"), including requirements with respect to diversification of assets,
distribution of income and sources of income. By so qualifying, each Fund
generally will not be subject to federal income tax to the extent that it
distributes investment company taxable income and net realized capital gains in
the manner required under the Code.

     Under the backup withholding rules of the Code, you may be subject to 31%
withholding of federal income tax on ordinary income dividends paid by a Fund.
In order to avoid this backup withholding, you must provide the Funds with a
correct taxpayer identification number or certify that you are otherwise exempt
from or not subject to backup withholding.

     Special tax treatment, including a penalty on certain pre-retirement
distributions, is accorded to accounts maintained as qualified retirement plans.
The foregoing discussion is intended for shareholders that are exempt from
federal income taxes. You should consult your own tax advisor as to the federal,
state and local tax consequences of ownership of shares of the Funds in your
particular circumstances.

                  MORE INFORMATION ABOUT STRATEGIES AND RISKS

     A Fund's risk profile is largely a factor of the principal securities in
which it invests and investment techniques that it uses. The following pages
discuss the risks associated with certain of the types of securities in which
the Funds may invest and certain of the investment practices that the Funds may
use. For more information about these and other types of securities and
investment techniques used by the Funds, see the Statement of Additional
Information. Unless indicated otherwise, the following descriptions apply to all
Funds.

     Many of the investment techniques and strategies discussed in this
Prospectus and in the Statement of Additional Information are discretionary,
which means that the Investment Manager or Sub-Adviser can decide whether to use
them or not. The Investment Manager or Sub-Adviser may also use investment
techniques or make investments in securities that are not a part of the Fund's
principal investment strategy.

     Corporate Debt Securities (ING Money Market Fund Only).  Debt securities
are subject to the risk of the issuer's inability to meet principal and interest
payments on the obligation and may also be subject to price volatility due to
<PAGE>   271
 10                                                              ING FUNDS TRUST
- --------------------------------------------------------------------------------

such factors as interest rate sensitivity, market perception of the
credit-worthiness of the issuer and general market liquidity. When interest
rates decline, the value of the debt securities can be expected to rise, and
when interest rates rise, the value of those securities can be expected to
decline. Debt securities with longer maturities tend to be more sensitive to
interest rate movements than those with shorter maturities.

     U.S. Government Agency Securities (ING Money Market Fund Only).  Some U.S.
Government agency securities may be subject to varying degrees of credit risk,
and all U.S. Government securities may be subject to price declines in the
securities due to changing interest rates.

     Other Investment Companies (All Funds).  Each Fund may invest up to 10% of
its assets in other unaffiliated investment companies. There is no limit with
regard to investments in affiliated investment companies. When a Fund invests in
other investment companies, you indirectly pay a proportionate share of the
expenses of that other investment company (including management fees,
administration fees, and custodial fees) in addition to the expenses of the
Fund.

     Restricted and Illiquid Securities (ING Money Market Fund Only).  Each Fund
may invest up to 10% of its net assets in restricted and illiquid securities. If
a security is illiquid, the Fund might be unable to sell the security at a time
when the sub-adviser might wish to sell, and the security could have the effect
of decreasing the overall level of the Fund's liquidity. Further, the lack of an
established secondary market may make it more difficult to value illiquid
securities, which could vary from the amount the Fund could realize upon
disposition. Restricted securities, i.e., securities subject to legal or
contractual restrictions on resale, may be illiquid. However, some restricted
securities may be treated as liquid, although they may be less liquid than
registered securities traded on established secondary markets.

     Mortgage-Related Securities (ING Money Market Fund Only).  Like other fixed
income securities, when interest rates rise, the value of a mortgage-backed
security generally will decline; however, when interest rates are declining, the
value of mortgage-backed securities with prepayment features may not increase as
much as other fixed income securities. The rate of prepayments on underlying
mortgages will affect the price and volatility of a mortgage-related security,
and may have the effect of shortening or extending the effective maturity of the
security beyond what was anticipated at the time of the purchase. Unanticipated
rates of prepayment on underlying mortgages can be expected to increase the
volatility of such securities. In addition, the value of these securities may
fluctuate in response to the market's perception of the creditworthiness of the
issuers of mortgage-related securities owned by a Fund. Additionally, although
mortgages and mortgage-related securities are generally supported by some form
of government or private guarantee and/or insurance, there is no assurance that
private guarantors or insurers will be able to meet their obligations.

     Asset-Backed Securities (ING Money Market Fund). Asset-backed securities
involve certain risks that are not posed by mortgage-related securities,
resulting mainly from the fact that asset-backed securities often do not contain
the benefit of a complete security interest in the related collateral. The risks
associated with asset-backed securities may be reduced by the addition of credit
enhancements such as a bank letter of credit or a third-party guarantee.

     Repurchase Agreements (All Funds).  Each Fund may enter into repurchase
agreements, which involve the purchase by a Fund of a security that the seller
has agreed to buy back. If the seller defaults and the collateral value
declines, the Fund might incur a loss. If the seller declares bankruptcy, the
Fund may not be able to sell the collateral at the desired time.

     Lending Portfolio Securities (All Funds).  In order to generate additional
income, each Fund may lend portfolio securities in an amount up to 33 1/3% of
its total assets to broker-dealers, major banks, or other recognized domestic
institutional borrowers of securities. As with other extensions of credit, there
are risks of delay in recovery or even loss of rights in the collateral should
the borrower default or fail financially.

     Borrowing (All Funds).  Each Fund may borrow for certain types of temporary
or emergency purposes subject to certain limits. Borrowing may exaggerate the
effect of any increase or decrease in the value of portfolio securities or the
net asset value of a Fund, and money borrowed will be subject to interest costs.
Interest costs on borrowings may fluctuate with changing market rates of
interest and may partially offset or exceed the return earned on borrowed funds.
Under adverse market conditions, a Fund might have to sell portfolio securities
to meet interest or principal payments at a time when fundamental investment
considerations would not favor such sales.

     Fundamental and Non-Fundamental Policies (All Funds).  Unless otherwise
stated, all investment objectives and policies are non-fundamental and may be
amended without shareholder approval.

     Percentage Investment Limitations (All Funds).  Unless otherwise stated,
percentage limitations in this prospectus apply at the time of investment.

                         INVESTMENT POLICIES AND RISKS

         The Prospectus discusses the investment objectives of the Funds and the
policies to be employed to achieve those objectives. This section contains
supplemental information concerning certain types of securities and other
instruments in which the Funds may invest, the investment policies and portfolio
strategies that the Funds may utilize, and certain risks attendant to such
investments, policies and strategies.

         COMMON STOCKS (All Funds, except Money Market Funds). Common stock
represents the residual ownership interest in the issuer after all of its
obligations and preferred stocks are satisfied. Common stock fluctuates in price
in response to many factors, including historical and prospective earnings of
the issuer, the value of its assets, general economic conditions, interest
rates, investor perceptions and market volatility.

         PREFERRED STOCKS (All Funds, except Money Market Funds). Preferred
stock has a preference over common stock in liquidation and generally in
dividends as well, but is subordinated to the liabilities of the issuer in all
respects. Preferred stock may or may not be convertible into common stock or
debt. As a general rule, the market value of preferred stock with a fixed
dividend rate and no conversion element varies inversely with interest rates and
perceived credit risk. Because preferred stock is junior to debt securities and
other obligations of the issuer, deterioration in the credit quality of the
issuer will cause greater changes in the value of a preferred stock than in a
more senior debt security with similar stated yield characteristics.

         U.S. TREASURY OBLIGATIONS. (All Funds). (All Funds). Each Fund may
invest in U.S. Treasury obligations, whose principal and interest are backed by
the full faith and credit of the United States Government. U.S. Treasury
obligations consist of bills, notes and bonds, and separately traded interest
and principal component parts of such obligations known as STRIPS, which
generally differ in their interest rates and maturities. U.S. Treasury bills,
which have original maturities of up to one year, notes, which have maturities
ranging from two years to 10 years and bonds, which have original maturities of
10 to 30 years, are direct obligations of the United States Government.

         U.S. GOVERNMENT SECURITIES. (All Funds except ING National Tax-Exempt
Money Market Fund and ING U.S. Treasury Money Market Fund). U.S. Government
securities are obligations issued or guaranteed by the U.S. Government, its
agencies or instrumentalities. U.S. Government securities include debt
securities issued or guaranteed by U.S. Government-sponsored enterprises and
federal agencies and instrumentalities. Some types of U.S. Government securities
are supported by the full faith and credit of the United States Government or
U.S. Treasury guarantees, such as mortgage-backed certificates guaranteed by the
Government National Mortgage Association ("GNMA"). Other types of U.S.
Government securities, such as obligations of the Student Loan Marketing
Association, provide recourse only to the credit of the agency or
instrumentality issuing the obligation. In the case of obligations not backed by
the full faith and credit of the United States Government, the investor must
look to the agency issuing or guaranteeing the obligation for ultimate
repayment.


                                                                               1
<PAGE>   279
         STRIPS AND ZERO COUPON SECURITIES. (All Funds). Each Fund may invest in
separately traded principal and interest components of securities backed by the
full faith and credit of the United States Treasury. The principal and interests
components of United States Treasury bonds with remaining maturities of longer
than ten years are eligible to be traded independently under the Separate
Trading of Registered Interest and Principal of Securities ("STRIPS") program.
Under the STRIPS program, the principal and interest components are separately
issued by the United States Treasury at the request of depository financial
institutions, which then trade the component parts separately. The interest
component of STRIPS may be more volatile than that of United States Treasury
bills with comparable maturities. The Funds will not actively trade in STRIPS.

         The Funds may invest in zero coupon securities. A zero coupon security
pays no interest to its holder during its life and is sold at a discount to its
face value at maturity. The market prices of zero coupon securities generally
are more volatile than the market prices of securities that pay interest
periodically and are more sensitive to changes in interest rates than non-zero
coupon securities having similar maturities and credit qualities.

         WHEN-ISSUED, DELAYED-DELIVERY SECURITIES AND FORWARD COMMITMENTS (All
Funds). The Funds may purchase securities on a when-issued or delayed-delivery
basis and may purchase or sell securities on a forward commitment basis.
When-issued or delayed-delivery transactions arise when securities are purchased
by a Fund with payment and delivery taking place in the future in order to
secure what is considered to be an advantageous price and yield to the Fund at
the time of entering into the transaction. A forward commitment transaction is
an agreement by a Fund to purchase or sell securities at a specified future
date. When a Fund engages in these transactions, the Fund relies on the buyer or
seller, as the case may be, to consummate the sale. Failure to do so may result
in the Fund missing the opportunity to obtain a price or yield considered to be
advantageous. When-issued and delayed-delivery transactions and forward
commitment transactions may be expected to occur a month or more before delivery
is due. However, no payment or delivery is made by a Fund until it receives
payment or delivery from the other party to the transaction. A separate account
containing only liquid assets equal to the value of purchase commitments will be
maintained until payment is made. The securities so purchased are subject to
market fluctuation during this period and no income accrues to the Fund until
settlement takes place. While the Funds normally enter into these transactions
with the intention of actually receiving or delivering the securities, they may
sell these securities before the settlement date or enter into new commitments
to extend the delivery date into the future, if the Sub-Adviser considers such
action advisable as a matter of investment strategy. Such securities have the
effect of leverage on the Funds and may contribute to volatility of a Fund's net
asset value.

         WARRANTS (All Funds). The Funds may purchase warrants. A warrant gives
the purchaser the right to purchase securities from the issuer at a specific
price (the strike price) for a limited period of time. The strike price of a
warrant typically is much lower than the current market price of the underlying
securities and therefore are subject to greater price fluctuations. As a result,
warrants may be more volatile investments than the underlying securities and may
offer greater potential for capital appreciation as well as capital loss.

         COMMERCIAL PAPER (All Funds except ING National Tax-Exempt Money Market
Fund and ING U.S. Treasury Money Market Fund). Commercial paper includes
short-term unsecured promissory notes, variable rate demand notes and variable
rate master demand notes issued by domestic and foreign bank holding companies,
corporations and financial institutions and similar taxable instruments issued
by government agencies and instrumentalities. All commercial paper purchased by
the ING Money Market Fund is, at the time of investment, (i) rated in the
highest rating

                                                                               2
<PAGE>   280
categories by at least two nationally recognized statistical rating
organizations ("NRSROs"), (ii) issued or guaranteed as to principal and interest
by issuers having an existing debt security rating in the highest rating
categories by a least two NRSROs, or (iii) securities which, if not rated or
single rated, are, in the opinion of the Fund's Sub-Adviser, of an investment
quality comparable to rated commercial paper in which the Fund may invest. See
"Variable Rate Demand Obligations and Floating Rate Instruments."

         DOMESTIC AND FOREIGN BANK OBLIGATIONS (All Funds except ING U.S.
Treasury Money Market Fund). These obligations include but are not restricted to
certificates of deposit, commercial paper, Yankee dollar certificates of
deposit, bankers' acceptances, Eurodollar certificates of deposit and time
deposits, promissory notes and medium-term deposit notes. The Funds will not
invest in any obligations of their affiliates, as defined under the Investment
Company Act of 1940 (the"1940 Act").

         Each Fund limits its investment in United States bank obligations to
obligations of United States banks (including foreign branches). Each Fund
limits its investment in foreign bank obligations to United States
dollar-denominated obligations of foreign banks (including United States
branches of foreign banks) which in the opinion of the Sub-Adviser, are of an
investment quality comparable to obligations of United States banks which may be
purchased by the Funds.

         Fixed time deposits may be withdrawn on demand by the investor, but may
be subject to early withdrawal penalties which vary depending upon market
conditions and the remaining maturity of the obligation. There are no
contractual restrictions on the right to transfer a beneficial interest in a
fixed time deposit to a third party, although there is no market for such
deposits. Investments in fixed time deposits subject to withdrawal penalties
maturing in more than seven days may not exceed 15% of the value of the net
assets of the Funds (10% of the value of the net assets in the case of money
market funds).

         Obligations of foreign banks involve somewhat different investment
risks than those affecting obligations of United States banks, including the
possibilities that their liquidity could be impaired because of future political
and economic developments, that the obligations may be less marketable than
comparable obligations of United States banks, that a foreign jurisdiction might
impose withholding taxes on interest income payable on those obligations, that
foreign deposits may be seized or nationalized, that foreign governmental
restrictions such as exchange controls may be adopted which might adversely
affect the payment of principal and interest on those obligations and that the
selection of those obligations may be more difficult because there may be less
publicly available information concerning foreign banks, or that the accounting,
auditing and financial reporting standards, practices and requirements
applicable to foreign banks may differ from those applicable to United States
banks. Foreign banks are not subject to examination by any United States
Government agency or instrumentality.

         Investments in Eurodollar and Yankee dollar obligations involve
additional risks. Most notably, there generally is less publicly available
information about foreign companies; there may be less governmental regulation
and supervision; they may use different accounting and financial standards; and
the adoption of foreign governmental restrictions may adversely affect the
payment of principal and interest on foreign investments. In addition, not all
foreign branches of United States banks are supervised or examined by regulatory
authorities as are United States banks, and such branches may not be subject to
reserve

                                                                               3

requirements.

         CORPORATE DEBT SECURITIES (All Funds except ING U.S. Treasury Money
Market Fund). Fund investment in these securities is limited to corporate debt
securities (corporate bonds, debentures, notes and similar corporate debt
instruments) which meet the rating criteria established for each Fund.

         The ratings of Standard & Poor's Corporation ("S&P"), Moody's Investors
Service, Inc. ("Moody's"), and other NRSROs represent their respective opinions
as to the quality of the obligations they undertake to rate. Ratings, however,
are general and are not absolute standards of quality. Consequently, obligations
with the same rating, maturity and interest rate may have different market
prices. After purchase by a Fund, a security may cease to be rated or its rating
may be reduced below the minimum required for purchase by the Fund. Neither
event will require a sale of such security by the Fund. However, each Fund's
Sub-Adviser will consider such event in its determination of whether the Fund
should continue to hold the security. To the extent the ratings given by an
NRSRO may change as a result of changes in such organizations or their rating
systems, the Sub-Adviser will attempt to use comparable ratings as standards for
investments in accordance with the investment policies contained in the
Prospectus and in this SAI.

         It is possible that unregistered securities purchased by a Fund in
reliance upon Section 4(2) or Rule 144A under the Securities Act of 1933 could
have the effect of increasing the level of the Fund's illiquidity to the extent
that qualified institutional buyers become, for a period, uninterested in
purchasing these securities.

         MORTGAGE-RELATED SECURITIES (All Funds except ING National Tax-Exempt
Bond Fund, ING National Tax-Exempt Money Market Fund and ING U.S. Treasury Money
Market Fund). To the extent permitted by the Funds' policies, the Funds may
invest in mortgage-backed securities, including those which represent undivided
ownership interests in pools of mortgages. The U.S. Government or the issuing
agency or instrumentality guarantees the payment of interest on and principal of
these securities. However, the guarantees do not extend to the yield or value of
the securities nor do the guarantees extend to the yield or value of a Fund's
shares. Consistent with the Funds' respective investment objective and policies,
mortgages backing the securities which may be purchased by the Funds include
conventional thirty-year fixed-rate mortgages, graduated payment mortgages,
fifteen-year mortgages, adjustable rate mortgages and balloon payment mortgages.
A balloon payment mortgage-backed security is an amortized mortgage security
with installments of principal and interest, the last installment of which is
predominantly principal. All of these mortgages can be used to create
pass-through securities. A pass-through security is formed when mortgages are
pooled together and undivided interests in the pool or pools are sold. The cash
flow from the mortgages is passed through to the holders of the securities in
the form of periodic payments of interest, principal and prepayments (net of a
service fee). Prepayments occur when the holder of an undivided mortgage prepays
the remaining principal before the mortgage's scheduled maturity date. As a
result of the pass-through of prepayments of principal on the underlying
securities, mortgage-backed securities are often subject to more rapid
prepayment of principal then their stated maturity would indicate. The remaining
expected average life of a pool of mortgage loans underlying a mortgage-backed
security is a prediction of when the mortgage loans will be repaid and is based
upon a variety of factors,

                                                                               4
<PAGE>   282
such as the demographic and geographic characteristics of the borrowers and the
mortgaged properties, the length of time that each of the mortgage loans has
been outstanding, the interest rates payable on the mortgage loans and the
current interest rate environment.

         During periods of declining interest rates, prepayment of mortgages
underlying mortgage-backed securities can be expected to accelerate. When
mortgage obligations are prepaid, the Funds reinvest the prepaid amounts in
securities, the yields of which reflect interest rates prevailing at that time.
Therefore, a Fund's ability to maintain a portfolio of high-yielding
mortgage-backed securities will be adversely affected to the extent that
prepayments of mortgages are reinvested in securities which have lower yields
than the prepaid mortgages. Moreover, prepayments of mortgages which underlie
securities purchased at a premium generally will result in capital losses.

         GNMA CERTIFICATES (All Funds except ING National Tax-Exempt Bond Fund,
ING National Tax-Exempt Money Market Fund and ING U.S. Treasury Money Market
Fund). Certificates of the Government National Mortgage Association (GNMA
Certificates) are mortgage-backed securities which evidence an undivided
interest in a pool or pools of mortgages. GNMA Certificates that the Funds may
purchase are the "modified pass-through" type, which entitle the holder to
receive timely payment of all interest and principal payments due on the
mortgage pool, net of fees paid to the "issuer" and GNMA, regardless of whether
or not the mortgagor actually makes the payment. The GNMA Certificates will
represent a pro rata interest in one or more pools of the following types of
mortgage loans: (i) fixed rate level payment mortgage loans; (ii) fixed rate
graduated payment mortgage loans; (iii) fixed rate growing equity mortgage
loans; (iv) fixed rate mortgage loans secured by manufactured (mobile) homes;
(v) mortgage loans on multifamily residential properties under construction;
(vi) mortgage loans on completed multifamily projects; (vii) fixed rate mortgage
loans as to which escrowed funds are used to reduce the borrower's monthly
payments during the early years of the mortgage loans ("buydown" mortgage
loans); (viii) mortgage loans that provide for adjustments in payments based on
periodic changes in interest rates or in other payment terms of the mortgage
loans; and (ix) mortgage-backed serial notes. All of these mortgage loans will
be FHA Loans or VA Loans and, except as otherwise specified above, will be
fully-amortizing loans secured by first liens on one- to-four-family housing
units. Legislative changes may be proposed from time to time in relation to the
Department of Housing and Urban Development which, if adopted, could alter the
viability of investing in GNMAs.

         FNMA CERTIFICATES (All Funds except ING National Tax-Exempt Bond Fund,
ING National Tax-Exempt Money Market Fund and ING U.S. Treasury Money Market
Fund). FNMA is a federally chartered and privately owned corporation organized
and existing under the Federal National Mortgage Association Charter Act. FNMA
provides funds to the mortgage market primarily by purchasing home mortgage
loans from local lenders, thereby replenishing their funds for additional
lending. FNMA acquires funds to purchase home mortgage loans from many capital
market investors that may not ordinarily invest in mortgage loans directly.

         Each FNMA Certificate will entitle the registered holder thereof to
receive amounts, representing such holder's pro rata interest in scheduled
principal payments and interest payments (at such FNMA Certificate's
pass-through rate, which is net of any servicing and guarantee fees on the
underlying mortgage loans), and any principal prepayments on the

                                                                               5
<PAGE>   283
mortgage loans in the pool represented by such FNMA Certificate and such
holder's proportionate interest in the full principal amount of any foreclosed
or otherwise finally liquidated mortgage loan. The full and timely payment of
principal and interest on each FNMA Certificate will be guaranteed by FNMA,
which guarantee is not backed by the full faith and credit of the U.S.
Government.

         Each FNMA Certificate will represent a pro rata interest in one or more
pools of FHA Loans, VA Loans or conventional mortgage loans (i.e., mortgage
loans that are not insured or guaranteed by any governmental agency) of the
following types: (i) fixed rate level payment mortgage loans; (ii) fixed rate
growing equity mortgage loans; (iii) fixed rate graduated payment mortgage
loans; (iv) variable rate California mortgage loans; (v) other adjustable rate
mortgage loans; and (vi) fixed rate mortgage loans secured by multifamily
projects.

         FHLMC SECURITIES (All Funds except ING National Tax-Exempt Bond Fund,
ING National Tax-Exempt Money Market Fund and ING U.S. Treasury Money Market
Fund)FHLMC SECURITIES. The Federal Home Loan Mortgage Corporation (FHLMC) was
created in 1970 through enactment of Title III of the Emergency Home Finance Act
of 1970 (FHLMC Act). Its purpose is to promote development of a nationwide
secondary market in conventional residential mortgages.

         The FHLMC issues two types of mortgage pass-through securities,
mortgage participation certificates (PCs) and guaranteed mortgage certificates
(GMCs). PCs resemble GNMA Certificates in that each PC represents a pro rata
share of all interest and principal payments made and owned on the underlying
pool. The FHLMC guarantees timely monthly payment of interest on PCs and the
ultimate payment of principal.

         GMCs also represent a pro rata interest in a pool of mortgages.
However, these instruments pay interest semi-annually and return principal once
a year in guaranteed minimum payments. The expected average life of these
securities is approximately ten years.

         FHLMC CERTIFICATES (All Funds except ING National Tax-Exempt Bond Fund,
ING National Tax-Exempt Money Market Fund and ING U.S. Treasury Money Market
Fund)FHLMC CERTIFICATES. FHLMC is a corporate instrumentality of the United
States created pursuant to the FHLMC Act. The principal activity of FHLMC
consists of the purchase of first lien, conventional, residential mortgage loans
and participation interests in such mortgage loans and the resale of the
mortgage loans so purchased in the form of mortgage securities, primarily FHLMC
Certificates.

         FHLMC guarantees to each registered holder of the FHLMC Certificate the
timely payment of interest at the rate provided for by such FHLMC Certificate,
whether or not received. FHLMC also guarantees to each registered holder of a
FHLMC Certificate ultimate collection of all principal on the related mortgage
loans, without any offset or deduction, but does not, generally, guarantee the
timely payment of scheduled principal. FHLMC may remit the amount due on account
of its guarantee of collection of principal at any time after default on an
underlying mortgage loan, but not later than 30 days following (i) foreclosure
sale, (ii) payment of a claim by any mortgage insurer or (iii) the expiration of
any right of redemption, whichever occurs later, but in any event no later than
one year after demand has been made

                                                                               6
<PAGE>   284
upon the mortgagor for accelerated payment of principal. The obligations of
FHLMC under its guarantee are obligations solely of FHLMC and are not backed by
the full faith and credit of the U.S. Government.

         FHLMC Certificates represent a pro rata interest in a group of mortgage
loans (a FHLMC Certificate group) purchased by FHLMC. The mortgage loans
underlying the FHLMC Certificates will consist of fixed rate or adjustable rate
mortgage loans with original terms to maturity of between ten and thirty years,
substantially all of which are secured by first liens on one- to four-family
residential properties or multifamily projects. Each mortgage loan must meet the
applicable standards set forth in the FHLMC Act. An FHLMC Certificate group may
include whole loans, participation interests in whole loans and undivided
interests in whole loans and participation comprising another FHLMC Certificate
group.

         The market value of mortgage securities, like other securities, will
generally vary inversely with changes in market interest rates, declining when
interest rates rise and rising when interest rates decline. However, mortgage
securities, while having comparable risk of decline during periods of rising
rates, usually have less potential for capital appreciation than other
investments of comparable maturities due to the likelihood of increased
prepayments of mortgages as interest rates decline. In addition, to the extent
such mortgage securities are purchased at a premium, mortgage foreclosures and
unscheduled principal prepayments generally will result in some loss of the
holders' principal to the extent of the premium paid. On the other hand, if such
mortgage securities are purchased at a discount, an unscheduled prepayment of
principal will increase current and total returns and will accelerate the
recognition of income which when distributed to shareholders will be taxable as
ordinary income.

         NON-AGENCY MORTGAGE-BACKED SECURITIES (All Funds except ING National
Tax-Exempt Bond Fund, ING National Tax-Exempt Money Market Fund and ING U.S.
Treasury Money Market Fund)NON-AGENCY MORTGAGE-BACKED SECURITIES (All Funds
except ING U.S. Treasury Money Market Fund). Certain non-agency private entities
also issue mortgage-backed securities. Other than lacking the guarantee by the
full faith and credit of the United States, the mortgage-backed securities
issued by private issuers generally have characteristics and risks comparable to
those issued by GNMA, as discussed above. Some mortgage-backed securities issued
by non-agency private issuers may be supported by a pool of mortgages not
acceptable to the agency issuers and thus may carry greater risks. Consistent
with the Funds' investment objective, policies and quality standards, the Funds
may invest in these mortgage-backed securities issued by non-agency private
issuers.

         ADJUSTABLE RATE MORTGAGE SECURITIES (All Funds except ING International
Bond Fund, ING National Tax-Exempt Bond Fund, ING U.S. Treasury Money Market
Fund and ING National Tax-Exempt Money Market Fund). Adjustable rate mortgage
securities (ARMS) are pass-through mortgage securities collateralized by
mortgages with adjustable rather than fixed rates. Generally, ARMS have a
specified maturity date and amortize principal over their life. In periods of
declining interest rates, there is a reasonable likelihood that ARMS will
experience increased rates of prepayment of principal. However, the major
difference between ARMS and fixed rate mortgage securities is that the interest
rate and the rate of amortization of principal of ARMS can and do change in
accordance with movements in a particular, pre-specified, published interest
rate index.


                                                                               7
<PAGE>   285
         The amount of interest on an ARM is calculated by adding a specified
amount, the "margin," to the index, subject to limitations on the maximum and
minimum interest that can be charged to the mortgagor during the life of the
mortgage or to maximum and minimum changes to that interest rate during a given
period. Because the interest rate on ARMS generally moves in the same direction
as market interest rates, the market value of ARMS tends to be more stable than
that of long-term fixed rate securities.

         There are two main categories of indices which serve as benchmarks for
periodic adjustments to coupon rates on ARMS: those based on U.S. Treasury
securities and those derived from a calculated measure such as a cost of funds
index or a moving average of mortgage rates. Commonly utilized indices include
the one-year and five-year constant maturity Treasury Note rates, the
three-month Treasury Bill rate, the 180-day Treasury Bill rate, rates on
longer-term Treasury securities, the 11th District Federal Home Loan Bank Cost
of Funds, the National Median Cost of Funds, the one-month or three-month London
Interbank Offered Rate (LIBOR), the prime rate of a specific bank, or commercial
paper rates. Some indices, such as the one-year constant maturity Treasury Note
rate, closely mirror changes in market interest rate levels. Others, such as the
11th District Home Loan Bank Cost of Funds index (often related to ARMS issued
by FNMA), tend to lag changes in market rate levels and tend to be somewhat less
volatile.

         COLLATERALIZED MORTGAGE OBLIGATIONS (All Funds except ING National
Tax-Exempt Bond Fund, ING National Tax-Exempt Money Market Fund and ING U.S.
Treasury Money Market Fund). Certain issuers of collateralized mortgage
obligations (CMOs), including certain CMOs that have elected to be treated as
Real Estate Mortgage Investment Conduits (REMICs), are not considered investment
companies pursuant to a rule adopted by the Securities and Exchange Commission
("SEC"), and the Funds may invest in the securities of such issuers without the
limitations imposed by the 1940 Act, on investments by the Funds in other
investment companies. In addition, in reliance on an earlier SEC interpretation,
a Fund's investments in certain other qualifying CMOs, which cannot or do not
rely on the rule, are also not subject to the limitation of the 1940 Act on
acquiring interests in other investment companies. In order to be able to rely
on the SEC's interpretation, these CMOs must be unmanaged, fixed asset issuers,
that (a) invest primarily in mortgage-backed securities, (b) do not issue
redeemable securities, (c) operate under general exemptive orders exempting them
from all provisions of the 1940 Act and (d) are not registered or regulated
under the 1940 Act as investment companies. To the extent that a Fund selects
CMOs or REMICs that cannot rely on the rule or do not meet the above
requirements, the Fund may not invest more than 10% of its assets in all such
entities and may not acquire more than 3% of the voting securities of any single
such entity.

         REAL ESTATE SECURITIES (All Funds except the Money Market Funds). The
Funds may invest in real estate investment trusts ("REITs") and other real
estate industry operating companies ("REOCs"). For purposes of a Fund's
investments, a REOC is a company that derives at least 50% of its gross revenues
or net profits from either (1) the ownership, development, construction,
financing, management or sale of commercial, industrial or residential real
estate, or (2) products or services related to the real estate industry, such as
building supplies or mortgage servicing. Investing in REITs involves certain
unique risks in addition to those risks associated with investing in the real
estate industry in general. Although the Funds will not invest directly in real
estate, the fund may invest in

                                                                               8
<PAGE>   286
equity securities of issuers primarily engaged in or related to the real estate
industry. Therefore, an investment in REITs is subject to certain risks
associated with the direct ownership of real estate and with the real estate
industry in general. These risks include, among others: possible declines in the
value of real estate; risks related to general and local economic conditions;
possible lack of availability of mortgage funds; overbuilding; extended
vacancies of properties; increases in competition, property taxes and operating
expenses; changes in zoning laws; costs resulting from the clean-up of, and
liability to third parties for damages resulting from, environmental problems;
casualty or condemnation losses; uninsured damages from floods, earthquakes or
other natural disasters; limitations on and variations in rents; and changes in
interest rates. To the extent that assets underlying the REITs' investments are
concentrated geographically, by property type or in certain other respects, the
REITs may be subject to certain of the foregoing risks to a greater extent.
Equity REITs may be affected by changes in the value of the underlying property
owned by the REITs, while mortgage REITs may be affected by the quality of any
credit extended. REITs are dependent upon management skills, are not
diversified, are subject to heavy cash flow dependency, default by borrowers and
self-liquidation. REITs are also subject to the possibilities of failing to
qualify for tax-free pass-through of income under the U.S. Internal Revenue Code
and failing to maintain their exemptions from registration under the 1940 Act.

         REITs (especially mortgage REITs) are also subject to interest rate
risks. When interest rates decline, the value of a REIT's investment in fixed
rate obligations can be expected to rise. Conversely, when interest rates rise,
the value of a REIT's investment in fixed rate obligations can be expected to
decline. In contrast, as interest rates on adjustable rate mortgage loans are
reset periodically, yields on a REIT's investment in such loans will gradually
align themselves to reflect changes in market interest rates, causing the value
of such investments to fluctuate less dramatically in response to interest rate
fluctuations than would investments in fixed rate obligations.

         Investing in REITs involves risks similar to those associated with
investing in small capitalization companies. REITs may have limited financial
resources, may trade less frequently and in a limited volume and may be subject
to more abrupt or erratic price movements than larger company securities.

         Investments in mortgage-related securities involve certain risks. In
periods of declining interest rates, prices of fixed income securities tend to
rise. However, during such periods, the rate of prepayment of mortgages
underlying mortgage-related securities tends to increase, with the result that
such prepayments must be reinvested by the issuer at lower rates. In addition,
the value of such securities may fluctuate in response to the market's
perception of the creditworthiness of the issuers of mortgage-related securities
owned by the Fund. Because investments in mortgage-related securities are
interest sensitive, the ability of the issuer to reinvest or to reinvest
favorably in underlying mortgages may be limited by government regulation or tax
policy. For example, action by the Board of Governors of the Federal Reserve
System to limit the growth of the nation's money supply may cause interest rates
to rise and thereby reduce the volume of new residential mortgages.
Additionally, although mortgages and mortgage-related securities are generally
supported by some form of government or private guarantees and/or insurance,
there is no assurance that private guarantors or insurers will be able to meet
their obligations.


                                                                               9
<PAGE>   287
         OPEN-END AND CLOSED-END INVESTMENT COMPANIES. (All Funds). Each Fund
may invest in shares of other open-end and closed-end management investment
companies, subject to the limitations of the 1940 Act and subject to such
investments being consistent with the overall objective and policies of the Fund
making such investment. The purchase of securities of other investment companies
results in duplication of expenses such that investors indirectly bear a
proportionate share of the expenses of such mutual funds including operating
costs, and investment advisory and administrative fees.

         ASSET-BACKED SECURITIES (All Funds except ING National Tax-Exempt Bond
Fund, ING National Tax-Exempt Money Market Fund and ING U.S. Treasury Money
Market Fund). The Funds are permitted to invest in asset-backed securities.
Through the use of trusts and special purpose subsidiaries, various types of
assets, primarily home equity loans and automobile and credit card receivables,
are being securitized in pass-through structures similar to the mortgage
pass-through structures described above. Consistent with the Funds' investment
objectives, policies and quality standards, the Funds may invest in these and
other types of asset-backed securities which may be developed in the future.

         Asset-backed securities involve certain risks that are not posed by
mortgage-related securities, resulting mainly from the fact that asset-backed
securities do not usually contain the benefit of a complete security interest in
the related collateral. For example, credit card receivables generally are
unsecured and the debtors are entitled to the protection of a number of state
and Federal consumer credit laws, some of which may reduce the ability to obtain
full payment. In the case of automobile receivables, due to various legal and
economic factors, proceeds from repossessed collateral may not always be
sufficient to support payments on these securities. The risks associated with
asset-backed securities are often reduced by the addition of credit enhancements
such as a letter of credit from a bank, excess collateral or a third-party
guarantee.

         FOREIGN SECURITIES (All Funds except, ING Mortgage Income Fund, ING
National Tax-Exempt Bond Fund and the Money Market Funds). As described in the
Prospectus, changes in foreign exchange rates will affect the value of
securities denominated or quoted in currencies other than the U.S. dollar.

         Since the Funds may invest in securities denominated in currencies
other than the U.S. dollar, and since those Funds may temporarily hold funds in
bank deposits or other money market investments denominated in foreign
currencies, a Fund may be affected favorably or unfavorably by exchange control
regulations or changes in the exchange rate between such currencies and the
dollar. Changes in foreign currency exchange rates will influence values within
the Fund from the perspective of U.S. investors. Changes in foreign currency
exchange rates may also affect the value of dividends and interest earned, gains
and losses realized on the sale of securities, and net investment income and
gains, if any, to be distributed to shareholders by the Fund. The rate of
exchange between the U.S. dollar and other currencies is determined by the
forces of supply and demand in the foreign exchange markets. These forces are
affected by the international balance of payments and other economic and
financial conditions, government intervention, speculation and other factors.

         The Funds may enter into foreign currency exchange contracts in order
to protect against uncertainty in the level of future foreign exchange rates. A
forward foreign

                                                                              10
<PAGE>   288
currency exchange contract involves an obligation to purchase or sell a specific
currency at a future date, which may be any fixed number of days from the date
of the contract agreed upon by the parties, at a price set at the time of the
contract. These contracts are entered into in the interbank market conducted
between currency traders (usually large commercial banks) and their customers.
Forward foreign currency exchange contracts may be bought or sold to protect a
Fund against a possible loss resulting from an adverse change in the
relationship between foreign currencies and the U.S. dollar, or between foreign
currencies. Although such contracts are intended to minimize the risk of loss
due to a decline in the value of the hedged currency, at the same time, they
tend to limit any potential gain which might result should the value of such
currency increase.

         The Funds also are authorized to use a proxy currency to hedge a
foreign exchange risk. This is done by using a forward foreign exchange contract
in a currency other than the currency of the asset subject to hedging. By
engaging in cross-hedging transactions, a Fund assumes the risk of imperfect
correlation between the subject currencies. This practice may present risks
different from, or in addition to, the risks associated with investments in
foreign currencies made to lock in the U.S. dollar price of a security.

         EMERGING COUNTRY AND EMERGING SECURITIES MARKETS (ING Emerging Markets
Equity Fund, ING International Equity Fund, ING High Yield Bond Fund, ING
Intermediate Bond Fund and ING International Bond Fund). Trading volume on
emerging country stock exchanges is substantially less than that on the New York
Stock Exchange. Further, securities of some emerging country or emerging market
companies are less liquid and more volatile than securities of comparable U.S.
companies. Similarly, volume and liquidity in most emerging country bond markets
is substantially less than in the U.S. and, consequently, volatility of price
can be greater than in the U.S. Fixed commissions on emerging country stock or
emerging market exchanges are generally higher than negotiated commissions on
U.S. exchanges, although the Fund endeavors to achieve the most favorable net
results on its portfolio transactions and may be able to purchase the securities
in which the Fund may invest on other stock exchanges where commissions are
negotiable. Foreign stock exchanges, brokers and listed companies are generally
subject to less government supervision and regulation than in the United States.
The customary settlement time for foreign securities may be longer than the
five-day customary settlement time for United States securities.

         Companies in emerging countries are not generally subject to uniform
accounting, auditing and financial reporting standards, practices and disclosure
requirements comparable to those applicable to U.S. companies. Consequently,
there may be less publicly available information about an emerging country
company than about a U.S. company. Further, there is generally less governmental
supervision and regulation of foreign stock exchanges, brokers and listed
companies than in the U.S.

         DEPOSITORY RECEIPTS (All Stock Funds, ING High Yield Bond Fund, ING
Intermediate Bond Fund and ING International Bond Fund). American Depositary
Receipts ("ADRs") are U.S. dollar-denominated receipts generally issued by
domestic banks, which evidence the deposit with the bank of the common stock of
a foreign issuer and which are publicly traded on exchanges or over-the-counter
in the United States.

         The Funds may invest in both sponsored and unsponsored ADR programs.

                                                                              11
<PAGE>   289
There are certain risks associated with investments in unsponsored ADR programs.
Because the non-U.S. company does not actively participate in the creation of
the ADR program, the underlying agreement for service and payment will be
between the depository and the shareholder. The company issuing the stock
underlying the ADR pays nothing to establish the unsponsored facility, as fees
for ADR issuance and cancellation are paid by brokers. Investors directly bear
the expenses associated with certificate transfer, custody and dividend payment.

         In an unsponsored ADR program, there also may be several depositories
with no defined legal obligations to the non-U.S. company. The duplicate
depositories may lead to marketplace confusion because there would be no central
source of information to buyers, sellers and intermediaries. The efficiency of
centralization gained in a sponsored program can greatly reduce the delays in
delivery of dividends and annual reports. In addition, with respect to all ADRs
there is always the risk of loss due to currency fluctuations.

         Investments in ADRs involve certain risks not typically involved in
purely domestic investments, including future foreign political and economic
developments, and the possible imposition of foreign governmental laws or
restrictions applicable to such investments. Securities of foreign issuers
through ADRs are subject to different economic, financial, political and social
factors. Individual foreign economies may differ favorably or unfavorably from
the U.S. economy in such respects as growth of gross national product, rate of
inflation, capital reinvestment, resources, self-sufficiency and balance of
payments position. With respect to certain countries, there is the possibility
of expropriation of assets, confiscatory taxation, political or social
instability or diplomatic developments which could adversely affect the value of
the particular ADR. There may be less publicly available information about a
foreign company than about a U.S. company, and there may be less governmental
regulation and supervision of foreign stock exchanges, brokers and listed
companies. In addition, such companies may use different accounting and
financial standards (and certain currencies may become unavailable for transfer
from a foreign currency), resulting in a Fund's possible inability to convert
proceeds realized upon the sale of portfolio securities of the affected foreign
companies immediately into U.S. currency. The Funds may also invest in European
Depository Receipts ("EDRs") and Global Depositary Receipts ("GDRs"). EDRs are
receipts issued in bearer form by a European financial institution and traded in
European securities' markets. GDRs are receipts issued globally. EDRs are
designed for trading in European Markets and GDRs are designed for trading in
non-U.S. securities markets. Investments in EDRs and GDRs involve similar risks
as ADRs.

         CONVERTIBLE SECURITIES (All Funds except ING National Tax-Exempt Bond
Fund and the Money Market Funds). Convertible securities may be converted at
either a stated price or stated rate into underlying shares of common stock and,
therefore, are deemed to be equity securities for purposes of the Funds'
management policies. Convertible securities have characteristics similar to both
fixed-income and equity securities. Convertible securities generally are
subordinated to other similar but nonconvertible securities of the same issuer,
although convertible bonds, as corporate debt obligations, enjoy seniority in
right of payment to all equity securities, and convertible preferred stock is
senior to common stock, of the same issuer. Because of the subordination
feature, however, convertible securities typically have lower ratings than
similar nonconvertible securities.


                                                                              12
<PAGE>   290
         Although to a lesser extent than with fixed-income securities, the
market value of convertible securities tends to decline as interest rates
increase and, conversely, tends to increase as interest rates decline. In
addition, because of the conversion feature, the market value of convertible
securities tends to vary with fluctuations in the market value of the underlying
common stock. A unique feature of convertible securities is that as the market
price of the underlying common stock declines, convertible securities tend to
trade increasingly on a yield basis, and so may not experience market value
declines to the same extent as the underlying common stock. When the market
price of the underlying common stock increases, the prices of the convertible
securities tend to rise as a reflection of the value of the underlying common
stock. While no securities investments are without risk, investments in
convertible securities generally entail less risk than investments in common
stock of the same issuer.

         Convertible securities are investments that provide for a stable stream
of income with generally higher yields than common stocks. There can be no
assurance of current income because the issuers of the convertible securities
may default on their obligations. A convertible security, in addition to
providing fixed income, offers the potential for capital appreciation through
the conversion feature, which enables the holder to benefit from increases in
the market price of the underlying common stock. There can be no assurance of
capital appreciation, however, because securities prices fluctuate. Convertible
securities, however, generally offer lower interest or dividend yields than
non-convertible securities of similar quality because of the potential for
capital appreciation.

         VARIABLE RATE DEMAND OBLIGATIONS AND FLOATING RATE. (All Funds). The
Funds may acquire variable rate demand obligations. Variable and floating rate
instruments are frequently not rated by credit rating agencies; however, unrated
variable and floating rate instruments purchased by a Fund will be determined by
the Sub-Adviser to be of comparable quality at the time of purchase to rated
instruments eligible for purchase by the Funds. In making such determinations,
the Sub-Adviser will consider the earning power, cash flows and other liquidity
ratios of the issuers of such instruments (such issuers include financial,
merchandising, investment banking, bank holding and other companies) and will
continuously monitor their financial condition. There may not be an active
secondary market with respect to a particular variable or floating rate
instrument purchased by a Fund. The absence of such an active secondary market
could make it difficult for a Fund to dispose of the variable or floating rate
instrument involved. In the event the issuer of the instrument defaulted on its
payment obligations, a Fund could, for this or other reasons, suffer a loss to
the extent of the default. Variable and floating rate instruments may be secured
by bank letters of credit, guarantees or lending commitments.

         GUARANTEED INVESTMENT CONTRACTS (All Funds except ING U.S. Treasury
Money Market Fund). The Funds may invest in Guaranteed Investment Contracts
("GICs") issued by insurance companies. Pursuant to such contracts, the Fund
makes cash contributions to a deposit fund of the insurance company's general
account. The insurance company then credits to the Fund on a monthly basis
guaranteed interest which is based on an index. The GICs provide that this
guaranteed interest will not be less than a certain minimum rate. The insurance
company may assess periodic charges against a GIC for expense and service costs
allocable to it, and the charges will be deducted from the value of the deposit
fund. In addition, because the Funds may not receive the principal amount of a
GIC from the

                                                                              13
<PAGE>   291
insurance company on seven days' notice or less, the GIC is considered an
illiquid investment, and, together with other instruments invested in by a Fund
which are not readily marketable, will not exceed 15% (10% in the case of ING
Money Market Funds) of a Fund's net assets. The term of a GIC will be one year
or less. In determining average weighted portfolio maturity, a GIC will be
deemed to have a maturity equal to the period of time remaining until the next
readjustment of the guaranteed interest rate.

         PRIVATE FUNDS (All Stock Funds and ING High Yield Bond Fund). The Funds
may invest in U.S. or foreign private limited partnerships or other investment
funds ("Private Funds"). Investments in Private Funds may be highly speculative
and volatile. Because Private Funds generally are investment companies for
purposes of the 1940 Act, the Fund's ability to invest in them will be limited.
In addition, Fund shareholders will remain subject to the Fund's expenses while
also bearing their pro rata share of the operating expenses of the Private
Funds. The ability of the Fund to dispose of interests in Private Funds is very
limited and involves risks, including loss of the Fund's entire investment in
the Private Fund.

         OPTIONS ON SECURITIES All Funds except ING National Tax-Exempt Bond
Fund and the Money Market Funds). Each Fund may purchase put and call options.
In addition, each Fund may write (sell) "covered" call options on securities as
long as it owns the underlying securities subject to the option or an option to
purchase the same underlying securities, having an exercise price equal to or
less than the exercise price of the "covered" option, or will establish and
maintain for the term of the option a segregated account consisting of cash or
other liquid securities ("eligible securities") to the extent required by
applicable regulation in connection with the optioned securities. A Fund may
write "covered" put options provided that, as long as the Fund is obligated as a
writer of a put option, the Fund will own an option to sell the underlying
securities subject to the option, having an exercise price equal to or greater
than the exercise price of the "covered" option, or it will deposit and maintain
in a segregated account eligible securities having a value equal to or greater
than the exercise price of the option. A call option gives the purchaser the
right to buy, and the writer the obligation to sell, the underlying security at
the exercise price during or at the end of the option period. A put option gives
the purchaser the right to sell, and the writer has the obligation to buy, the
underlying security at the exercise price during or at the end of the option
period. The premium received for writing an option will reflect, among other
things, the current market price of the underlying security, the relationship of
the exercise price to such market price, the price volatility of the underlying
security, the option period, supply and demand and interest rates. The Funds may
write or purchase spread options, which are options for which the exercise price
may be a fixed dollar spread or yield spread between the security underlying the
option and another security that is used as a benchmark. The exercise price of
an option may be below, equal to or above the current market value of the
underlying security at the time the option is written. The buyer of a put who
also owns the related security is protected by ownership of a put option against
any decline in that security's price below the exercise price less the amount
paid for the option. The ability to purchase put options allows a Fund to
protect capital gains in an appreciated security it owns, without being required
to actually sell that security. At times a Fund would like to establish a
position in a security upon which call options are available. By purchasing a
call option, a Fund is able to fix the cost of acquiring the security, this
being the cost of the call plus the exercise price of the option. This procedure
also provides some protection from an unexpected downturn in the

                                                                              14
<PAGE>   292
market because a Fund is only at risk for the amount of the premium paid for the
call option which it can, if it chooses, permit to expire.

         During the option period the covered call writer gives up the potential
for capital appreciation above the exercise price should the underlying asset
rise in value, and the secured put writer retains the risk of loss should the
underlying security decline in value. For the covered call writer, substantial
appreciation in the value of the underlying asset would result in the security
being "called away." For the secured put writer, substantial depreciation in the
value of the underlying security would result in the security being "put to" the
writer. If a covered call option expires unexercised, the writer realizes a gain
in the amount of the premium received. If the covered call option writer has to
sell the underlying security because of the exercise of a call option, it
realizes a gain or loss from the sale of the underlying security, with the
proceeds being increased by the amount of the premium.

         If a secured put option expires unexercised, the writer realizes a gain
from the amount of the premium. If the secured put writer has to buy the
underlying security because of the exercise of the put option, the secured put
writer incurs an unrealized loss to the extent that the current market value of
the underlying security is less than the exercise price of the put option.
However, this would be offset in whole or in part by gain from the premium
received.

         OVER-THE-COUNTER OPTIONS (All Funds except ING National Tax-Exempt Bond
Fund and the Money Market Funds). As indicated in the prospectus, each Fund may
deal in over-the-counter traded options ("OTC options"). OTC options differ from
exchange-traded options in several respects. They are transacted directly with
dealers and not with a clearing corporation, and there is a risk of
nonperformance by the dealer as a result of the insolvency of such dealer or
otherwise, in which event a Fund may experience material losses. However, in
writing options the premium is paid in advance by the dealer. OTC options are
available for a greater variety of securities, and a wider range of expiration
dates and exercise prices, than are exchange-traded options. Since there is no
exchange, pricing is normally done by reference to information from market
makers, which information is carefully monitored by the investment manager and
verified in appropriate cases.

         A writer or purchaser of a put or call option can terminate it
voluntarily only by entering into a closing transaction. In the case of OTC
options, there can be no assurance that a continuous liquid secondary market
will exist for any particular option at any specific time. Consequently, a Fund
may be able to realize the value of an OTC option it has purchased only by
exercising it or entering into a closing sale transaction with the dealer that
issued it. Similarly, when a Fund writes an OTC option, it generally can close
out that option prior to its expiration only by entering into a closing purchase
transaction with the dealer to which the Fund originally wrote it. If a covered
call option writer cannot effect a closing transaction, it cannot sell the
underlying security until the option expires or the option is exercised.
Therefore, a covered call option writer of an OTC option may not be able to sell
an underlying security even though it might otherwise be advantageous to do so.
Likewise, a secured put writer of an OTC option may be unable to sell the
securities pledged to secure the put for other investment purposes while it is
obligated as a put writer. Similarly, a purchaser of such put or call option
might also find it difficult to terminate its position on a timely basis in the
absence of a secondary market.


                                                                              15
<PAGE>   293
         The staff of the SEC has taken the position that purchased options not
traded on registered domestic securities exchanges and the assets used as cover
for written options not traded on such exchanges are generally illiquid
securities. However, the staff has also opined that, to the extent a mutual fund
sells an OTC option to a primary dealer that it considers creditworthy and
contracts with such primary dealer to establish a formula price at which the
fund would have the absolute right to repurchase the option, the fund would only
be required to treat as illiquid the portion of the assets used to cover such
option equal to the formula price minus the amount by which the option is
in-the-money. Pending resolution of the issue, the Funds will treat such options
and, except to the extent permitted through the procedure described in the
preceding sentence, assets as subject to each such Fund's limitation on
investments in securities that are not readily marketable.

         OPTIONS ON INDICES (All Funds except ING National Tax-Exempt Bond Fund
and the Money Market Funds). Each Fund also may purchase and write call and put
options on securities indices in an attempt to hedge against market conditions
affecting the value of securities that the Fund owns or intends to purchase, and
not for speculation. Through the writing or purchase of index options, a Fund
can achieve many of the same objectives as through the use of options on
individual securities. Options on securities indices are similar to options on a
security except that, rather than the right to take or make delivery of a
security at a specified price, an option on a securities index gives the holder
the right to receive, upon exercise of the option, an amount of cash if the
closing level of the securities index upon which the option is based is greater
than, in the case of a call, or less than, in the case of a put, the exercise
price of the option. This amount of cash is equal to the difference between the
closing price of the index and the exercise price of the option. The writer of
the option is obligated, in return for the premium received, to make delivery of
this amount. Unlike security options, all settlements are in cash and gain or
loss depends upon price movements in the market generally (or in a particular
industry or segment of the market), rather than upon price movements in
individual securities. Price movements in securities that the Fund owns or
intends to purchase will probably not correlate perfectly with movements in the
level of an index since the prices of such securities may be affected by
somewhat different factors and, therefore, the Fund bears the risk that a loss
on an index option would not be completely offset by movements in the price of
such securities.

         When a Fund writes an option on a securities index, it will segregate
and mark-to-market eligible securities to the extent required by applicable
regulation. In addition, where the Fund writes a call option on a securities
index at a time when the contract value exceeds the exercise price, the Fund
will segregate and mark-to-market, until the option expires or is closed out,
cash or cash equivalents equal in value to such excess.

         Each Fund may also purchase and sell options on other appropriate
indices, as available, such as foreign currency indices. Options on a securities
index involve risks similar to those risks relating to transactions in financial
futures contracts described above. Also, an option purchased by a Fund may
expire worthless, in which case the fund would lose the premium paid therefore.

         FOREIGN CURRENCY OPTIONS (All Funds except ING Mortgage Income Fund,
ING National Tax-Exempt Bond Fund and the Money Market Funds). Each Fund may

                                                                              16
<PAGE>   294
engage in foreign currency options transactions. A foreign currency option
provides the option buyer with the right to buy or sell a stated amount of
foreign currency at the exercise price at a specified date or during the option
period. A call option gives its owner the right, but not the obligation, to buy
the currency, while a put option gives its owner the right, but not the
obligation, to sell the currency. The option seller (writer) is obligated to
fulfill the terms of the option sold if it is exercised. However, either seller
or buyer may close its position during the option period in the secondary market
for such options any time prior to expiration.

         A call rises in value if the underlying currency appreciates.
Conversely, a put rises in value if the underlying currency depreciates. While
purchasing a foreign currency option can protect the Fund against an adverse
movement in the value of a foreign currency, it does not limit the gain which
might result from a favorable movement in the value of such currency. For
example, if a Fund were holding securities denominated in an appreciating
foreign currency and had purchased a foreign currency put to hedge against a
decline in the value of the currency, it would not have to exercise its put.
Similarly, if the Fund has entered into a contract to purchase a security
denominated in a foreign currency and had purchased a foreign currency call to
hedge against a rise in value of the currency but instead the currency had
depreciated in value between the date of purchase and the settlement date, the
Fund would not have to exercise its call but could acquire in the spot market
the amount of foreign currency needed for settlement.

         DOLLAR ROLL TRANSACTIONS (All Funds except ING National Tax-Exempt Bond
Fund and the Money Market Funds). In connection with their ability to purchase
securities on a when-issued or forward commitment basis, the Funds may enter
into "dollar rolls" in which the Funds sell securities for delivery in the
current month and simultaneously contracts with the same counterparty to
repurchase similar (same type, coupon and maturity) but not identical securities
on a specified future date. The Funds give up the right to receive principal and
interest paid on the securities sold. However, the Funds would benefit to the
extent of any difference between the price received for the securities sold and
the lower forward price for the future purchase plus any fee income received.
Unless such benefits exceed the income and capital appreciation that would have
been realized on the securities sold as part of the dollar roll, the use of this
technique will diminish the investment performance of the Funds compared with
what such performance would have been without the use of dollar rolls. The Funds
will hold and maintain in a segregated account until the settlement date liquid
assets in an amount equal to the value of the when-issued or forward commitment
securities. The benefits derived from the use of dollar rolls may depend, among
other things, upon the Sub-Advisers' ability to predict interest rates
correctly. There is no assurance that dollar rolls can be successfully employed.
In addition, the use of dollar rolls by the Funds while remaining substantially
fully invested increases the amount of a Fund's assets that are subject to
market risk to an amount that is greater than the Fund's net asset value, which
could result in increased volatility of the price of the Fund's shares.

         SWAP AGREEMENTS (All Funds except the Money Market Funds). To manage
its exposure to different types of investments, the Funds may enter into
interest rate, total return, currency and mortgage (or other asset) swap
agreements and may purchase and sell interest rate "caps," "floors" and
"collars." In a typical interest rate swap agreement, one party agrees to make
regular payments equal to a floating interest rate on a specified amount

                                                                              17
<PAGE>   295
(the "notional principal amount") in return for payments to a fixed interest
rate on the same amount for a specified period. Total return swap agreements are
similar to interest rate swap agreements, except the numerical amount is tied to
a market-linked return. If a swap agreement provides for payment in different
currencies, the parties may also agree to exchange the notional principal
amount. Mortgage swap agreements are similar to interest rate swap agreements,
except that the notional principal amount is tied to a reference pool of
mortgages. In a cap or floor, one party agrees, usually in return for a fee, to
make payments under particular circumstances. For example, the purchaser of an
interest rate cap has the right to receive payments to the extent a specified
interest rate exceeds an agreed upon level; the purchaser of an interest rate
floor has the right to receive payments to the extent a specified interest rate
falls below an agreed upon level. A collar entitles the purchaser to receive
payments to the extent a specified interest rate falls outside an agreed upon
range.

         Swap agreements may involve leverage and may be highly volatile;
depending on how they are used, they may have a considerable impact on the
Fund's performance. Swap agreements involve risks depending upon the
counterparties creditworthiness and ability to perform as well as the Fund's
ability to terminate its swap agreements or reduce its exposure through
offsetting transactions. The Sub-Advisers monitor the creditworthiness of
counterparties to these transactions and intend to enter into these transactions
only when they believe the counterparties present minimal credit risks and the
income expected to be earned from the transaction justifies the attendant risks.

         FOREIGN CURRENCY FUTURES TRANSACTIONS (All Funds except ING Mortgage
Income Fund, ING National Tax-Exempt Bond Fund and the Money Market Funds). As
part of its financial futures transactions, each Fund may use foreign currency
futures contracts and options on such futures contracts. Through the purchase or
sale of such contracts, a Fund may be able to achieve many of the same
objectives as through forward foreign currency exchange contracts more
effectively and possibly at a lower cost.

         Unlike forward foreign currency exchange contracts, foreign currency
futures contracts and options on foreign currency futures contracts are
standardized as to amount and delivery period and are traded on boards of trade
and commodities exchanges. It is anticipated that such contracts may provide
greater liquidity and lower cost than forward foreign currency exchange
contracts.

         FOREIGN GOVERNMENT OBLIGATIONS; SECURITIES OF SUPRANATIONAL ENTITIES
(All Funds except ING Mortgage Income Fund, ING National Tax-Exempt Bond Fund
and the Money Market Funds). A Fund may invest in obligations issued or
guaranteed by one or more foreign governments or any of their political
subdivisions, agencies or instrumentalities that are determined by the
Sub-Adviser to be of comparable quality to the other obligations in which the
Fund may invest. Such securities also include debt obligations of supranational
entities. Supranational entities include international organizations designated
or supported by governmental entities to promote economic reconstruction or
development and international banking institutions and related government
agencies. Examples include the International Bank for Reconstruction and
Development (the World Bank), the European Coal and Steel Community, the Asian
Development Bank and the InterAmerican Development Bank.


                                                                              18
<PAGE>   296
         INTEREST RATE FUTURES CONTRACTS (All Funds except ING National
Tax-Exempt Bond Fund and the Money Market Funds). The Funds may purchase and
sell interest rate futures contracts ("futures contracts") as a hedge against
changes in interest rates. A futures contract is an agreement between two
parties to buy and sell a security for a set price on a future date. Future
contracts are traded on designated "contracts markets" which, through their
clearing corporations, guarantee performance of the contracts. Currently, there
are futures contracts based on securities such as long-term U.S. Treasury bonds,
U.S. Treasury notes, GNMA Certificates and three-month U.S. Treasury bills.

         Generally, if market interest rates increase, the value of outstanding
debt securities declines (and vice versa). Entering into a futures contract for
the sale of securities has an effect similar to the actual sale of securities,
although sale of the futures contract might be accomplished more easily and
quickly. For example, if a Fund holds long-term U.S. Government securities and
the Sub-Adviser anticipates a rise in long-term interest rates, it could, in
lieu of disposing of its portfolio securities, enter into futures contracts for
the sale of similar long-term securities. If rates increased and the value of a
Fund's portfolio securities declined, the value of a Fund's futures contracts
would increase, thereby protecting the Fund by preventing its net asset value
from declining as much as it otherwise would have. Similarly, entering into
futures contracts for the purchase of securities has an effect similar to actual
purchase of the underlying securities, but permits the continued holding of
securities other than the underlying securities. For example, if the Sub-Adviser
expects long-term interest rates to decline, a Fund might enter into futures
contracts for the purchase of long-term securities, so that it could gain rapid
market exposure that may offset anticipated increases in the cost of securities
it intends to purchase, while continuing to hold higher-yielding short-term
securities or waiting for the long-term market to stabilize. Futures
transactions may fail as hedging techniques where price movements of the
underlying securities do not follow price movements of the portfolio securities
subject to the hedge. The loss with respect to futures transactions is
potentially unlimited. Also, the Funds may be unable to control losses by
closing its position where a liquid secondary market does not exist.

         SHORT SALES(ING International Equity Fund, ING Emerging Markets Equity
Fund, ING Intermediate Bond Fund and ING High Yield Bond Fund). The Funds may
sell a security it does not own in anticipation of a decline in the market value
of that security (short sales). To complete such a transaction, the Fund must
borrow the security to make delivery to the buyer. The Fund then is obligated to
replace the security borrowed by purchasing it at market price at the time of
replacement. The price at such time may be more or less than the price at which
the security was sold by the Fund. Until the security is replaced, the Fund is
required to pay to the lender any dividends or interest which accrue during the
period of the loan. To borrow the security, the Fund also may be required to pay
a premium, which would increase the cost of the security sold. The proceeds of
the short sale will be retained by the broker, to the extent necessary to meet
margin requirements, until the short position is closed out. Until the Fund
replaces a borrowed security, the Funds will maintain daily a segregated account
with the Funds' custodian, consisting of liquid assets, at such a level that (i)
the amount deposited in the account plus the amount deposited with the broker as
collateral will equal the current value of the security sold short and (ii) the
amount deposited in the segregated account plus the amount deposited with the
broker as collateral will not be less than the market value of the security at
the time it was sold short. The Fund will incur a loss as a result of the short
sale if the price of the security increases between the date

                                                                              19
<PAGE>   297
of the short sale and the date on which the Fund replaces the borrowed security.
The Funds will realize a gain if the security declines in price between those
dates. This result is the opposite of what one would expect from a cash purchase
of a long position in a security. The amount of any gain will be decreased, and
the amount of any loss increased, by the amount of any premium, dividends or
interest the Fund may be required to pay in connection with a short sale. No
more than 25% of a Fund's net assets will be, when added together: (i) deposited
as collateral for the obligation to replace securities borrowed to effect short
sales; and (ii) allocated to segregated accounts in connection with short sales.
Short sales against-the-box are not subject to this 25% limit.

         In a short sale "against-the-box," a Fund enters into a short sale of a
security which the Fund owns or has the right to obtain at no added cost. Not
more than 25% of a Fund's net assets (determined at the time of the short sale
against-the-box) may be subject to such sales.

         LOANS OF PORTFOLIO SECURITIES. (All Funds). The Funds may lend their
portfolio securities to brokers, dealers and financial institutions, provided:
(1) the loan is secured continuously by collateral consisting of U.S. Government
securities or cash or letters of credit maintained on a daily mark-to-market
basis in an amount at least equal to the current market value of the securities
loaned; (2) the Funds may at any time call the loan and obtain the return of the
securities loaned within five business days; (3) the Funds will receive any
interest or dividends paid on the loaned securities; and (4) the aggregate
market value of securities loaned will not at any time exceed one-third of the
total assets of a particular Fund.

         The Funds will earn income for lending their securities because cash
collateral pursuant to these loans will be invested in short-term money market
instruments. In connection with lending securities, the Funds may pay reasonable
finders, administrative and custodial fees. Loans of securities involve a risk
that the borrower may fail to return the securities or may fail to provide
additional collateral.

         REPURCHASE AGREEMENTS. (All Funds). The Funds may invest in securities
subject to repurchase agreements with U.S. banks or broker-dealers. Such
agreements may be considered to be loans by the Funds for purposes of the 1940
Act. A repurchase agreement is a transaction in which the seller of a security
commits itself at the time of the sale to repurchase that security from the
buyer at a mutually agreed upon time and price. The repurchase price exceeds the
sale price, reflecting an agreed-upon interest rate effective for the period the
buyer owns the security subject to repurchase. The agreed-upon rate is unrelated
to the interest rate on that security. Each Fund's Sub-Adviser will monitor the
value of the underlying security at the time the transaction is entered into and
at all times during the term of the repurchase agreement to ensure that the
value of the security always equals or exceeds the repurchase price. In the
event of default by the seller under the repurchase agreement, the Funds may
have problems in exercising their rights to the underlying securities and may
incur costs and experience time delays in connection with the disposition of
such securities.

         BORROWING. (All Funds). A Fund may borrow from banks up to 33 1/3% of
the current value of its net assets to purchase securities and for temporary or
emergency

                                                                              20
<PAGE>   298
purposes and those borrowings may be secured by the pledge of not more than
33 1/3% of the current value of that Fund's net assets.

         REVERSE REPURCHASE AGREEMENTS (All Funds). A Fund may borrow funds by
selling portfolio securities to financial institutions such as banks and
broker/dealers and agreeing to repurchase them at a mutually specified date and
price ("reverse repurchase agreements"). Reverse repurchase agreements involve
the risk that the market value of the securities sold by a Fund may decline
below the repurchase price. A Fund will pay interest on amounts obtained
pursuant to a reverse repurchase agreement. While reverse repurchase agreements
are outstanding, a Fund will maintain in a segregated account, other liquid
assets (as determined by the Board) of an amount at least equal to the market
value of the securities, plus accrued interest, subject to the agreement.

         LOWER-RATED SECURITIES. (ING Emerging Markets Equity Fund, ING High
Yield Bond Fund, ING Intermediate Bond Fund and ING International Bond Fund).
Lower-rated securities are lower-rated bonds commonly referred to as junk bonds
or high-yield/high-risk securities. These securities are rated below Baa by
Moody's or below BBB by S&P. As described in the Prospectus, certain of the
Funds may invest in lower rated and unrated securities of comparable quality
subject to the restrictions stated in the Prospectus.

         Growth of High-Yield High-Risk Bond Market. The widespread expansion of
government, consumer and corporate debt within the U.S. economy has made the
corporate sector more vulnerable to economic downturns or increased interest
rates. Further, an economic downtown could severely disrupt the market for
lower-rated bonds and adversely affect the value of outstanding bonds and the
ability of the issuers to repay principal and interest. The market for
lower-rated securities may be less active, causing market price volatility and
limited liquidity in the secondary market. This may limit the Funds' ability to
sell such securities at their market value. In addition, the market for these
securities may be adversely affected by legislative and regulatory developments.
Credit quality in the junk bond market can change suddenly and unexpectedly, and
even recently issued credit ratings may not fully reflect the actual risks
imposed by a particular security.

         Sensitivity to Interest Rate and Economic Changes. Lower rated bonds
are very sensitive to adverse economic changes and corporate developments.
During an economic downturn or substantial period of rising interest rates,
highly leveraged issuers may experience financial stress that would adversely
affect their ability to service their principal and interest payment
obligations, to meet projected business goals, and to obtain additional
financing. If the issuer of a bond defaulted on its obligations to pay interest
or principal or entered into bankruptcy proceedings, the Fund may incur losses
or expenses in seeking recovery of amounts owed to it. In addition, periods of
economic uncertainty and change can be expected to result in increased
volatility of market prices of high-yield, high-risk bonds and the Fund's net
asset value.

         Payment Expectations. High-yield, high-risk bonds may contain
redemption or call provisions. If an issuer exercised these provisions in a
declining interest rate market, the Fund would have to replace the security with
a lower yielding security, resulting in a decreased return for investors.
Conversely, a high-yield, high-risk bond's value will decrease

                                                                              21
<PAGE>   299
in a rising interest rate market, as will the value of the Fund's assets. If the
Fund experiences significant unexpected net redemptions, this may force it to
sell high-yield, high-risk bonds without regard to their investment merits,
thereby decreasing the asset base upon which expenses can be spread and possibly
reducing the Fund's rate of return.

         Liquidity and Valuation. There may be a little trading in the secondary
market for particular bonds, which may affect adversely the Fund's ability to
value accurately or dispose of such bonds. Adverse publicity and investor
perception, whether or not based on fundamental analysis, may decrease the
values and liquidity of high-yield, high-risk bonds, especially in a thin
market.

         ILLIQUID SECURITIES. Each Fund has adopted a non-fundamental policy
with respect to investments in illiquid securities. Historically, illiquid
securities have included securities subject to contractual or legal restrictions
on resale because they have not been registered under the Securities Act of
1933, as amended ("Securities Act"), securities that are otherwise not readily
marketable and repurchase agreements having a maturity of longer than seven
days. Securities that have not been registered under the Securities Act are
referred to as private placements or restricted securities and are purchased
directly from the issuer or in the secondary market. Mutual funds do not
typically hold a significant amount of these restricted or other illiquid
securities because of the potential for delays on resale and uncertainty in
valuation. Limitations on resale may have an adverse effect on the marketability
of portfolio securities and a mutual fund might be unable to dispose of
restricted or other illiquid securities promptly or at reasonable prices and
might thereby experience difficulty satisfying redemptions within seven days. A
mutual fund might also have to register such restricted securities in order to
dispose of them resulting in additional expense and delay. Adverse market
conditions could impede such a public offering of securities.

         In recent years, however, a large institutional market has developed
for certain securities that are not registered under the Securities Act,
including repurchase agreements, commercial paper, foreign securities, municipal
securities and corporate bonds and notes. Institutional investors depend on
either an efficient institutional market in which the unregistered security can
be readily resold or on the issuer's ability to honor a demand for repayment.
The fact that there are contractual or legal restrictions on resale to the
general public or to certain institutions may not be indicative of the liquidity
of such investments.

         Each Fund may also invest in restricted securities issued under Section
4(2) of the Securities Act ("Section 4(2)"), which exempts from registration
"transactions by an issuer not involving any public offering." Section 4(2)
instruments are restricted in the sense that they can only be resold through the
issuing dealer and only to institutional investors; they cannot be resold to the
general public without registration. Restricted securities issued under Section
4(2) (other than certain commercial paper issued pursuant to Section 4(2)
discussed below) will be treated as illiquid and subject to the Fund's
investment restriction on illiquid securities.

         Pursuant to procedures adopted by the Board of Trustees, the Funds may
treat certain commercial paper issued pursuant to Section 4(2) as a liquid
security and not subject to the Funds' investment restriction on illiquid
investments. Section 4(2) commercial paper may be considered liquid only if all
of the following conditions are met: (i) the Section 4(2)

                                                                              22
<PAGE>   300
commercial paper must not be traded flat (i.e. without accrued interest) or be
in default as to principal or interest; and (ii) the Section 4(2) commercial
paper must be rated in one of the two highest rating categories by at least two
NRSROs, or if only NRSRO rates the security, by that NRSRO, or if the security
is unrated, the security has been determined to be of equivalent quality.

         The SEC has adopted Rule 144A, which allows a broader institutional
trading market for securities otherwise subject to restrictions on resale to the
general public. Rule 144A establishes a "safe harbor" from the registration
requirements of the Securities Act applicable to resales of certain securities
to qualified institutional buyers. It is the intent of the Funds to invest,
pursuant to procedures established by the Board of Trustees and subject to
applicable investment restrictions, in securities eligible for resale under Rule
144A which are determined to be liquid based upon the trading markets for the
securities.

         Pursuant to guidelines adopted by and under the supervision of the
Board of Trustees, the Sub-Adviser will monitor the liquidity of restricted
securities in a Fund's portfolio. In reaching liquidity decisions, the
Sub-Adviser will consider, among other things, the following factors: (1) the
frequency of trades and quotes for the security over the course of six months or
as determined in the discretion of the Sub-Adviser; (2) the number of dealers
wishing to purchase or sell the security and the number of other potential
purchasers over the course of six months or as determined in the discretion of
the Sub-Adviser; (3) dealer undertakings to make a market in the security; (4)
the nature of the security and the marketplace in which it trades (e.g., the
time needed to dispose of the security, the method of soliciting offers and the
mechanics of the transfer); and (5) other factors, if any, which the Sub-Adviser
deems relevant.

         Rule 144A securities and Section 4(2) commercial paper which are
determined to be liquid based upon their trading markets will not, however, be
required to be included among the securities considered to be illiquid.
Investments in Rule 144A securities and Section 4(2) commercial paper could have
the effect of increasing Fund illiquidity.

                         ADDITIONAL RISK CONSIDERATIONS

         The following pages discuss additional risk considerations associated
with certain of the types of securities in which the Funds may invest and
certain of the investment practices that the Funds may use. Unless indicated
otherwise, the following descriptions apply to all Funds.

         GENERAL. The price per share of each of the Funds will fluctuate with
changes in value of the investments held by the Fund. For example, the value of
a Fund's shares will generally fluctuate inversely with the movements in
interest rates. Shareholders of a Fund should expect the value of their shares
to fluctuate with changes in the value of the securities owned by the Fund.
There is, of course, no assurance that a Fund will achieve its investment
objective or be successful in preventing or minimizing the risk of loss that is
inherent in investing in particular types of investment products. In order to
attempt to minimize that risk, the Sub-Adviser monitors developments in the
economy, the securities markets, and with each particular issuer. Also, each
diversified Fund (i.e., all funds except the ING Global Brand Names Fund, ING
Focus Fund, ING Global Real Estate Fund, ING

                                                                              23
<PAGE>   301
Internet Fund, ING Internet Fund II, ING Quality of Life Fund and ING
International Bond Fund) is managed within certain limitations that restrict the
amount of the Fund's investment in any single issuer. The Money Market Funds
will attempt to maintain a stable $1.00 net asset value per share.

         EQUITY SECURITIES. Investments in equity securities in general are
subject to market risks that may cause their prices to fluctuate over time. The
value of convertible equity securities is also affected by prevailing interest
rates, the credit quality of the issuer and any call provisions. Fluctuations in
the value of equity securities in which a Fund invests will cause the net asset
value of the Fund to fluctuate.

                  Investments in mid- and small-capitalization companies involve
greater risk than is customarily associated with larger, more established
companies due to the greater business risks of small size, limited markets and
financial resources, narrow product lines and the frequent lack of depth of
management. The securities of smaller companies are often traded
over-the-counter and may not be traded in volumes typical on a national
securities exchange. Consequently, the securities of smaller companies may have
limited market stability and may be subject to more abrupt or erratic market
movements than securities of larger, more established growth companies or the
market averages in general.

         REAL ESTATE SECURITIES While the Funds will not invest in real estate
directly, the ING Global Real Estate Fund may be subject to risks similar to
those associated with the direct ownership of real estate (in addition to
securities markets risks) because of its policy of concentration in the
securities of companies in the real estate industry. These risks include
declines in the value of real estate, risks related to general and local
economic conditions, dependency on management skill, heavy cash flow dependency,
possible lack of availability of mortgage funds, overbuilding, extended
vacancies of properties, increased competition, increases in property taxes and
operating expenses, changes in zoning laws, losses due to costs resulting from
the clean-up of environmental problems, liability to third parties for damages
resulting from environmental problems, casualty or condemnation losses,
limitations on rents, changes in neighborhood values and in the appeal of
properties to tenants and changes in interest rates.

         In addition to these risks, Equity REITs may be affected by changes in
the value of the underlying property owned by the trusts, while Mortgage REITs
may be affected by the quality of any credit they extend. Further, Equity REITs
and Mortgage REITs are dependent upon management skills and generally may not be
diversified. Equity REITs and Mortgage REITs are also subject to heavy cash flow
dependency, defaults by borrowers and self-liquidation. In addition, Equity
REITs and Mortgage REITs could possibly fail to qualify for tax-free
pass-through of income under the Code or to maintain their exemptions from
registration under the 1940 Act. The above factors may also adversely affect a
borrower's or a lessee's ability to meet its obligations to the REIT. In the
event of a default by a borrower or lessee, the REIT may experience delays in
enforcing its rights as a mortgagee or lessor and may incur substantial costs
associated with protecting its investments. In addition to the foregoing risks,
certain "special purpose" REITs may invest their assets in specific real estate
sectors, such as hotel REITs, nursing home REITs or warehouse REITs, and are
therefore subject to the risks associated with adverse developments in any such
sectors.



                                                                              24
<PAGE>   302
         FOREIGN SECURITIES AGREEMENTS Investing in the securities of issuers in
any foreign country including ADRs and EDRs involves special risks and
considerations not typically associated with investing in U.S. companies. These
include differences in accounting, auditing and financial reporting standards;
generally higher commission rates on foreign portfolio transactions; the
possibility of nationalization, expropriation or confiscatory taxation; adverse
changes in investment or exchange control regulations (which may include
suspension of the ability to transfer currency from a country); and political
instability which could affect U.S. investments in foreign countries.
Additionally, foreign securities and dividends and interest payable on those
securities may be subject to foreign taxes, including taxes withheld from
payments on those securities. Foreign securities often trade with less frequency
and volume than domestic securities and, therefore, may exhibit greater price
volatility. Additional costs associated with an investment in foreign securities
may include higher custodial fees than apply to domestic custodial arrangements
and transaction costs of foreign currency conversions. Changes in foreign
exchange rates also will affect the value of securities denominated or quoted in
currencies other than the U.S. dollar. The Funds' investments may be affected
either unfavorably or favorably by fluctuations in the relative rates of
exchange between the currencies of different nations, by exchange control
regulations and by indigenous economic and political developments.

         FIXED INCOME SECURITIES. The market value of a Fund's fixed income
investments will change in response to interest rate changes and other factors.
During periods of falling interest rates, the values of outstanding fixed income
securities generally rise. Conversely, during periods of rising interest rates,
the values of such securities generally decline. Securities with longer
maturities are subject to greater fluctuations in value than securities with
shorter maturities. Changes by an NRSRO in the rating of any fixed income
security and in the ability of an issuer to make payments of interest and
principal also affect the value of these investments. Changes in the value of a
Fund's securities will not affect cash income derived from these securities but
will affect the Fund's net asset value.

         Securities held by a Fund that are guaranteed by the U.S. Government,
its agencies or instrumentalities guarantee only the payment of principal and
interest on the guaranteed securities, and do not guarantee the securities'
yield or value or the yield or value of a Fund's shares.

         OPTIONS AND FUTURES CONTRACTS. One risk involved in the purchase and
sale of futures and options is that a Fund may not be able to effect closing
transactions at a time when it wishes to do so. Positions in futures contracts
and options on futures contracts may be closed out only on an exchange or board
of trade that provides an active market for them, and there can be no assurance
that a liquid market will exist for the contract or the option at any particular
time. To mitigate this risk, each Fund will ordinarily purchase and write
options only if a secondary market for the options exists on a national
securities exchange or in the over-the-counter market. Another risk is that
during the option period, if a Fund has written a covered call option, it will
have given up the opportunity to profit from a price increase in the underlying
securities above the exercise price in return for the premium on the option
(although the premium can be used to offset any losses or add to a Fund's
income) but, as long as its obligation as a writer continues, such Fund will
have retained the risk of loss should the price of the underlying security
decline. Investors should note that because of the volatility of the market
value of the underlying security, the loss from investing

                                                                              25
<PAGE>   303
in futures transactions is potentially unlimited. In addition, a Fund has no
control over the time when it may be required to fulfill its obligation as a
writer of the option. Once a Fund has received an exercise notice, it cannot
effect a closing transaction in order to terminate its obligation under the
option and must deliver the underlying securities at the exercise price.

         The Funds' successful use of stock index futures contracts, options on
such contracts and options on indices depends upon the ability of the
Sub-Adviser to predict the direction of the market and is subject to various
additional risks. The correlation between movements in the price of the futures
contract and the price of the securities being hedged is imperfect and the risk
from imperfect correlation increases in the case of stock index futures as the
composition of the Funds' portfolios diverges from the composition of the
relevant index. Such imperfect correlation may prevent the Funds from achieving
the intended hedge or may expose the Funds to risk of loss. In addition, if the
Funds purchase futures to hedge against market advances before they can invest
in common stock in an advantageous manner and the market declines, the Funds
might create a loss on the futures contract. Particularly in the case of options
on stock index futures and on stock indices, the Funds' ability to establish and
maintain positions will depend on market liquidity. The successful utilization
of options and futures transactions requires skills different from those needed
in the selection of the Funds' portfolio securities. The Funds believe that the
Sub-Adviser possesses the skills necessary for the successful utilization of
such transactions.

         The Funds are permitted to engage in bona fide hedging transactions (as
defined in the rules and regulations of the Commodity Futures Trading
Commission) without any quantitative limitations. Futures and related option
transactions which are not for bona fide hedging purposes may be used provided
the total amount of the initial margin and any option premiums attributable to
such positions does not exceed 5% of each Fund's liquidating value after taking
into account unrealized profits and unrealized losses, and excluding any
in-the-money option premiums paid. The Funds will not market, and are not
marketing, themselves as commodity pools or otherwise as vehicles for trading in
futures and related options. The Funds will segregate liquid assets such as
cash, U.S. Government securities or other liquid high-grade debt obligations to
cover the futures and options.

         TECHNIQUES INVOLVING LEVERAGE. Utilization of leveraging involves
special risks and may involve speculative investment techniques. Certain Funds
may borrow for other than temporary or emergency purposes, lend their
securities, enter reverse repurchase agreements, and purchase securities on a
when issued or forward commitment basis. In addition, certain Funds may engage
in dollar roll transactions. Each of these transactions involves the use of
"leverage" when cash made available to the Fund through the investment technique
is used to make additional portfolio investments. The Funds use these investment
techniques only when the Sub-Adviser believes that the leveraging and the
returns available to the Fund from investing the cash will provide shareholders
a potentially higher return.

         Leverage exists when a Fund achieves the right to a return on a capital
base that exceeds the investment the Fund has invested. Leverage creates the
risk of magnified capital losses which occur when losses affect an asset base,
enlarged by borrowings or the creation of liabilities, that exceeds the equity
base of the Fund. Leverage may involve the creation of a liability that requires
the Fund to pay interest (for instance, reverse repurchase agreements) or

                                                                              26
<PAGE>   304
the creation of a liability that does not entail any interest costs (for
instance, forward commitment transactions).

         The risks of leverage include a higher volatility of the net asset
value of a Fund's shares and the relatively greater effect on the net asset
value of the shares caused by favorable or adverse market movements or changes
in the cost of cash obtained by leveraging and the yield obtained from investing
the cash. So long as a Fund is able to realize a net return on its investment
portfolio that is higher than interest expense incurred, if any, leverage will
result in higher current net investment income being realized by such Fund than
if the Fund were not leveraged. On the other hand, interest rates change from
time to time as does their relationship to each other depending upon such
factors as supply and demand, monetary and tax policies and investor
expectations. Changes in such factors could cause the relationship between the
cost of leveraging and the yield to change so that rates involved in the
leveraging arrangement may substantially increase relative to the yield on the
obligations in which the proceeds of the leveraging have been invested. To the
extent that the interest expense involved in leveraging approaches the net
return on a Fund's investment portfolio, the benefit of leveraging will be
reduced, and, if the interest expense on borrowings were to exceed the net
return to shareholders, such Fund's use of leverage would result in a lower rate
of return than if the Fund were not leveraged. Similarly, the effect of leverage
in a declining market could be a greater decrease in net asset value per share
than if a Fund were not leveraged. In an extreme case, if a Fund's current
investment income were not sufficient to meet the interest expense of
leveraging, it could be necessary for such Fund to liquidate certain of its
investments at an inappropriate time. The use of leverage may be considered
speculative.

         NON-DIVERSIFIED INVESTMENT COMPANIES (ING Global Brand Names Fund, ING
Focus Fund, ING Global Real Estate Fund, ING Internet Fund, ING Internet Fund
II, ING Quality of Life Fund and ING International Bond Fund). The Funds are
classified as non-diversified investment companies under the 1940 Act, which
means that each Fund is not limited by the 1940 Act in the proportion of its
assets that it may invest in the obligations of a single issuer. The investment
of a large percentage of a Fund's assets in the securities of a small number of
issuers may cause that Fund's share price to fluctuate more than that of a
diversified investment company.

         CONCENTRATION (ING Global Information Technology Fund, ING Global
Communications Fund, ING Internet Fund, ING Internet Fund II, ING Global Real
Estate Fund and ING Quality of Life Fund). The Funds "concentrate" (for purposes
of the 1940 Act) their assets in securities related to a particular sector or
industry, which means that at least 25% of its assets will be invested in these
assets at all times. As a result, each Fund may be subject to greater market
fluctuation than a fund which has securities representing a broader range of
investment alternatives.

         WRAPPER AGREEMENTS (ING Stable Value Fund). The ING Stable Value Fund
expects that its use of Wrapper Agreements should allow it to maintain a stable
net asset value per share and to pay dividends to shareholders which reflect the
interest income and market value gains and losses of the Covered Assets under
the Wrapper Agreement less the expenses incurred by the Fund. However, there can
be no assurance that the Fund will maintain such a stable net asset value per
share, or that you will achieve the same investment return as you would realize
by directly investing in the Covered Assets. Additionally, as a

                                                                              27
<PAGE>   305
result of the Wrapper Agreements, you could realize more or less than the actual
investment returns of the Covered Assets depending upon the timing of your
purchases and redemptions of shares, as well as those of other shareholders. In
addition, the following risks are inherent in Wrapper Agreements, and could
prevent the Fund from achieving its investment objective.

         Failure to Obtain Replacement Wrapper Agreements. If a Wrapper
Agreement matures or terminates, or a Wrap Provider defaults, the Fund may be
unable to obtain a replacement Wrapper Agreement or a Wrapper Agreement with
substantially the same terms as the maturing or terminating agreement. In that
event, the Fund may not be able to maintain a stable net asset value per share.
If at such time the value of the Covered Assets is less than Book Value, the
Fund may be required to reduce its net asset value accordingly. Likewise, if at
such time the value of the Covered Assets is greater than Book Value, the Fund's
net asset value may increase. In either case, you may experience unexpected
fluctuations in the value of your shares. Further, if the new Wrapper Agreement
contains unfavorable terms, such as a higher Wrap Provider fee, the returns of
the Fund may be negatively affected.

         Unwrapped Fund Assets. It is currently contemplated that all of the
Fund's assets, other than certain short-term assets, will be Covered Assets. The
Fund, however, may not be able to purchase or maintain Wrapper Agreements with
respect to all Covered Assets. Moreover, the Fund may determine not to enter
into Wrapper Agreements with respect to certain of its non-short-term assets, or
the Fund may be unable to obtain Wrapper Agreements for all such assets. In that
event, the Fund may not be able to achieve its investment policy of maintaining
a stable net asset value per share, because fluctuations in the market value of
assets that are not covered by Wrapper Agreements may affect the Fund's net
asset value per share.

         Valuation of Wrapper Agreements. The value of each Wrapper Agreement
will be determined in accordance with policies and procedures established by the
Board of Trustees on behalf of the Fund. If a Wrap Provider defaults on its
obligations under a Wrapper Agreement or any other agreement, becomes insolvent,
or enters insolvency proceedings, the value of the Wrapper Agreement will be
reduced to reflect the Wrap Provider's inability to meet its obligations under
the Wrapper Agreement. Further, if the Wrap Provider's credit ratings are
downgraded or if the Board of Trustees determines that the Wrap Provider may no
longer be able to satisfy its obligations under a Wrapper Agreement in a timely
manner, the value of the Wrapper Agreement may be reduced to reflect the
uncertainty that the Wrap Provider will be able to meet its obligations under
the Wrapper Agreement. In any such case, the Fund may not be able to maintain a
stable net asset value per share and may experience a decrease or increase in
its net asset value per share.

         Dependence Upon a Limited Number of Wrap Providers. It is currently
intended that the Fund will at all times maintain Wrapper Agreements with at
least two Wrap Providers and that the Covered Assets will be allocated
relatively equally among such Wrapper Agreements. However, there is no guarantee
that the Fund will be able to maintain such Wrapper Agreements, or that the
Covered Assets will be allocated equally among the Wrap Providers. Therefore, it
is possible that the Fund may be totally dependent upon one Wrap Provider for
coverage of all of the Covered Assets or that one or more Wrapper Agreements
will bear a disproportionate portion of the Covered Assets.


                                                                              28
<PAGE>   306
         Liability of Wrap Providers. A Wrap Provider's payment obligation is
limited to the Book Value of its Wrapper Agreement. If the Fund enters into
Wrapper Agreements with more than one Wrap Provider, no Wrap Provider will be
jointly liable for the payment obligations of any other Wrap Provider.
Therefore, if a Wrap Provider defaults on its obligations under a Wrapper
Agreement, the Fund will not be able to look to any other Wrap Provider for
satisfaction of such obligations. In that event, the Fund may seek to promptly
replace that Wrap Provider with a substitute Wrap Provider. However, there can
be no guarantee that any such replacement will be feasible, or that any
substitute Wrap Provider will agree to the same terms as the original Wrap
Provider. Further, if at the time of the replacement, the value of the Covered
Assets is less than the Book Value of the defaulted Wrapper Agreement, it may be
more difficult for the Fund to obtain a replacement Wrapper Agreement from a
qualified Wrap Provider. In addition, the fees charged by such substitute Wrap
Provider could be significantly greater than those previously charged and could
reduce the ultimate returns provided to shareholders.

         Book Value Limitations. A Wrap Provider may limit its exposure under a
Wrapper Agreement to a specified maximum dollar value. Although the Fund intends
to require all Wrap Providers to agree to provide wrap coverage with respect to
a minimum of 50% of the Covered Assets, there can be no guarantee that each Wrap
Provider will agree to this requirement. Further, a large, sudden increase in
the amount of share purchases could result in the Fund being unable to obtain
sufficient Wrapper Agreements to cover all of its non-short-term assets.

         Illiquid Asset. Currently, there is no active trading market for
Wrapper Agreements, and none is expected to develop. Accordingly, Wrapper
Agreements may not be able to be liquidated within seven days at fair market
value. Therefore, the Wrapper Agreements will be considered illiquid. As such,
at the time of purchase, the fair market value of a Wrapper Agreement, together
with the fair market values of all other illiquid assets, will not exceed
fifteen percent (15%) of the fair market value of the Fund's net assets.

         PORTFOLIO  TURNOVER. Each Fund will adjust its portfolio as it deems
advisable in view of prevailing or anticipated market conditions or fluctuations
in interest rates to accomplish its respective investment objective. For
example, each Fund may sell portfolio securities in anticipation of an adverse
market movement. Other than for tax purposes, frequency of portfolio turnover
will not be a limiting factor if a Fund considers it advantageous to purchase or
sell securities. The Funds do not anticipate that the respective annual
portfolio turnover rates will exceed the following: ING Large Cap Growth Fund
100%; ING Growth & Income Fund 100%; ING Mid Cap Growth Fund 100%; ING Small Cap
Growth Fund 100%; ING Global Brand Names Fund 100%; ING International Equity
Fund 200%; ING European Equity Fund 100%; ING Tax Efficient Equity Fund 50%; ING
Tax Efficient Equity Value Fund 50%; ING Focus Fund 100%; ING Global Information
Technology Fund 100%; ING Global Communications Fund 100%; ING Internet Fund
250%; ING Internet Fund II 250%; ING Balanced Fund 100%; ING Emerging Markets
Equity Fund 200%; ING Global Real Estate Fund 100%; ING Quality of Life Fund
100%; ING Intermediate Bond Fund 300%; ING High Yield Bond Fund 350%; ING
International Bond Fund 150%; ING Stable Value Fund 150%; ING Mortgage Income
Fund 200%; and ING National Tax-Exempt Bond Fund 150%. A high rate of portfolio
turnover involves


                                                                              29
<PAGE>   307
correspondingly greater transaction expenses than a lower rate, which expenses
must be borne by each Fund and its shareholders.


                             INVESTMENT RESTRICTIONS

The Funds have adopted investment restrictions numbered 1 through 8 as
fundamental policies, which cannot be changed without approval by the holders of
a majority (as defined in the 1940 Act) of a Fund's outstanding voting shares.
Investment restriction number 9 is not a fundamental policy and may be changed
by vote of a majority of the members of the Board of Trustees at any time.

         Each Fund, except as indicated, may not:

         (1) Borrow money, except to the extent permitted under the 1940 Act
(which currently limits borrowing to no more than 33-1/3% of the value of a
Fund's total assets). For purposes of this Investment Restriction, the entry
into reverse repurchase agreements, options, forward contracts, futures
contracts, including those relating to indices, and options on futures contracts
or indices shall not constitute borrowing.

         (2) Issue senior securities, except insofar as a Fund may be deemed to
have issued a senior security in connection with any repurchase agreement or any
permitted borrowing;

         (3) Make loans, except loans of portfolio securities and except that a
Fund may enter into repurchase agreements with respect to its portfolio
securities and may purchase the types of debt instruments described in its
Prospectus or this SAI;

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

         (5) Purchase, hold or deal in real estate, or oil, gas or other mineral
leases or exploration or development programs, but a Fund may purchase and sell
securities that are secured by real estate or issued by companies that invest or
deal in real estate or real estate investment trusts.

         (6) Engage in the business of underwriting securities of other issuers,
except to the extent that the disposal of an investment position may technically
cause it to be considered an underwriter as that term is defined under the
Securities Act of 1933;

         (7) Purchase securities on margin, except that a Fund may obtain such
short-term credits as may be necessary for the clearance of purchases and sales
of securities;

         (8) Purchase a security if, as a result, more than 25% of the value of
its total assets would be invested in securities of one or more issuers
conducting their principal business activities in the same industry, provided
that (a) this limitation shall not apply to obligations issued or guaranteed by
the U.S. Government or its agencies and instrumentalities; (b) wholly-owned
finance companies will be considered to be in the industries of their parents;

                                                                              30
<PAGE>   308
(c) utilities will be divided according to their services. For example, gas, gas
transmission, electric and gas, electric, and telephone will each be considered
a separate industry; (d) the ING Money Market Fund will not be limited in its
investments in obligations issued by domestic banks; and (e) the ING Global
Information Technology Fund, ING Global Communications Fund, ING Internet Fund,
ING Internet Fund II, ING Global Real Estate Fund and ING Quality of Life Fund
will concentrate their investments as described in the Prospectus.

         (9) Invest more than 15%, 10% in the case of the ING Money Market
Funds, of the value of its net assets in investments which are illiquid
(including repurchase agreements having maturities of more than seven calendar
days, variable and floating rate demand and master demand notes not requiring
receipt of principal note amount within seven days' notice and securities of
foreign issuers which are not listed on a recognized domestic or foreign
securities exchange).

         In addition, all Funds except for the ING Global Brand Names Fund, ING
Focus Fund, ING Global Real Estate Fund, ING Internet Fund, ING Internet Fund
II, ING Quality of Life Fund and ING International Bond Fund are diversified
funds. As such, each will not, with respect to 75% (100% with respect to the ING
Money Market Funds) of their total assets, invest more than 5% of its total
assets in the securities of any one issuer (except for U.S. Government
securities) or purchase more than 10% of the outstanding voting securities of
any one issuer. The ING Money Market Funds may invest up to 25% of their total
assets in the first tier securities of a single issuer for a period of up to
three business days after the acquisition thereof provided that the Fund may not
invest in the securities of more than one issuer in accordance with this
provision at any time.

         Each Stock Fund, except ING Mid Cap Growth, ING International Equity,
ING Emerging Markets Equity and ING Focus Funds, will only purchase fixed income
securities that are rated investment grade, i.e., rated at least BBB by S&P or
Baa by Moody's, or have an equivalent rating from another NRSRO, or if unrated,
are determined to be of comparable quality by the Sub-Adviser. The ING Mid Cap
Growth Fund and the ING Focus Fund, will only purchase fixed income securities
that are rated A or better by S&P or Moody's or have an equivalent rating from
another NRSRO, or if unrated, are determined to be of comparable quality by the
applicable Sub-Adviser. The ING International Equity Fund will only purchase
fixed income securities that are rated at least AA+ by S&P or Aa-2 by Moody's,
or have an equivalent rating from another NRSRO, or if unrated, are determined
to be of comparable quality by the Sub-Adviser. The ING Emerging Markets Equity
Fund may invest in fixed income securities that are rated below investment
grade. Money market securities, certificates of deposit, banker's acceptance and
commercial paper purchased by the Stock Funds must be rated in one of the two
top rating categories by an NRSRO or, if not rated, determined to be of
comparable quality by the Stock Fund's Sub-Adviser.

         If a percentage limitation is satisfied at the time of investment, a
later increase or decrease in such percentage resulting from a change in the
value of a Fund's investments will not constitute a violation of such
limitation, except that any borrowing by a Fund that exceeds the fundamental
investment limitations stated above must be reduced to meet such limitations
within the period required by the 1940 Act (currently three days). Otherwise, a
Fund may continue to hold a security even though it causes the Fund to exceed a
percentage limitation because of fluctuation in the value of the Fund's assets.

         The higher distribution fee attributable to Class B, Class C, and Class
X shares is designed to permit an investor to purchase such shares through
registered representatives of the Distributor and other broker-dealers without
the assessment of an initial sales load and at the same time to permit the
Distributor to compensate its registered representatives and other
broker-dealers in connection with the sale of such shares. The distribution fee
for all classes may be used by the Distributor for the purpose of financing any
activity which is primarily intended to result in the sale of shares of the
applicable Fund. For example, such distribution fee may be used by the
Distributor: (a) to compensate broker-dealers, including the Distributor and its
registered representatives, for their sale of Fund shares, including the
implementation of various incentive programs with respect to broker-dealers,
banks, and other financial institutions, (b) to pay for interest and other
borrowing costs incurred by the distributor; and (c) to pay other advertising
and promotional expenses in connection with the distribution of Fund shares.
These advertising and promotional expenses include, by way of example but not by
way of limitation, costs of prospectuses for other than current shareholders;
preparation and distribution of sales literature; advertising of any type;
expenses of branch offices provided jointly by the Distributor and affiliated
companies; and compensation paid to and expenses incurred by officers, employees
or representatives of the Distributor or of other broker-dealers, banks, or
other financial institutions, including travel, entertainment, and telephone
expenses.

         Agreements implementing the Plan of Distribution (the "Implementation
Agreements"), including agreements with dealers wherein such dealers agree for a
fee to act

                                                                              37
<PAGE>   315
as agents for the sale of the Funds' shares, are in writing and have been
approved by the Board of Trustees. All payments made pursuant to the Plan of
Distribution are made in accordance with written agreements.

         The continuance of the Plan of Distribution and the Implementation
Agreements must be specifically approved at least annually by a vote of the
Trust's Board of Trustees and by a vote of the Trustees who are not interested
persons of the Trust and have no direct or indirect financial interest in the
Plan or any Implementation Agreement (the "Independent Trustees") at a meeting
called for the purpose of voting on such continuance. The Plan of Distribution
may be terminated at any time by a vote of the majority of the Independent
Trustees or by a vote of the holders of a majority of the outstanding shares of
a Fund or the applicable class of a Fund. In the event the Plan of Distribution
is terminated in accordance with its terms, the affected Fund (or class) will
not be required to make any payments for distribution expenses incurred after
the termination date, although the Board of Trustees may allow the Funds to pay
distribution expenses to the Distributor which were incurred before the Plan was
terminated. Each Implementation Agreement terminates automatically in the event
of its assignment and may be terminated at any time by a vote of the majority of
the Independent Trustees or by a vote of the holders of a majority of the
outstanding shares of a Fund (or the applicable class) on not more than 60 days'
written notice to any other party to the Implementation Agreement. The Plan of
Distribution may not be amended to increase materially the amount to be spent
for distribution without shareholder approval. All material amendments to the
Plan of Distribution must be approved by a vote of the Trust's Board of Trustees
and by a vote of the Independent Trustees.

         In approving the Plan of Distribution, the Trustees determined, in the
exercise of their business judgment and in light of their fiduciary duties as
Trustees, that there is a reasonable likelihood that the Plan will benefit the
Funds and their shareholders. The Board of Trustees believes that expenditure of
the Funds' assets for distribution expenses under the Plan of Distribution
should assist in the growth of the Funds which will benefit the Funds and their
shareholders through increased economies of scale, greater investment
flexibility, greater portfolio diversification and less chance of disruption of
planned investment strategies. The Plan of Distribution will be renewed only if
the Trustees make a similar determination for each subsequent year of the Plan.
There can be no assurance that the benefits anticipated from the expenditure of
the Funds' assets for distribution will be realized. While the Plan of
Distribution is in effect, all amounts spent by the Funds pursuant to the Plan
and the purposes for which such expenditures were made must be reported
quarterly to the Board of Trustees for its review. Distribution expenses
attributable to the sale of more than one class of shares of a Fund will be
allocated at least annually to each class of shares based upon the ratio in
which the sales of each class of shares bears to the sales of all of the shares
of such Fund. In addition, the selection and nomination of those Trustees who
are not interested persons of the Trust are committed to the discretion of the
Independent Trustees during such period.

         John J. Pileggi, as an interested person of the Trust, may be deemed to
have a financial interest in the operation of the Plan of Distribution and the
Implementation Agreements.

<PAGE>   316
Shareholder Servicing Plan

                  Each Fund has adopted a Shareholder Servicing Plan pursuant to
which it may pay a service fee up to an annual rate of 0.25% of the average
daily net assets of its Class A, Class B, Class C and Class X shares to various
banks, trust companies, broker-dealers or other financial organizations
including the Manager and its affiliates (collectively, "Service Organizations")
that provide certain administrative and support services to their customers who
own shares of the Funds. These services may include, but are not limited to, (a)
answering routine customer inquiries regarding the Funds; (b) assisting
customers in changing dividend options, account designations and addresses, and
in enrolling into any of the several investment plans offered by the Funds; (c)
assisting in processing purchase and redemption transactions, including
arranging wire transfers, transmitting and receiving funds, and verifying
customer signatures; and (d) providing such other similar services directly to
their customers to the extent permitted under applicable statutes, rules and
regulations.

                  Some Service Organizations may impose additional or different
conditions on their clients, such as requiring their clients to invest more than
the minimum initial or subsequent investments specified by the Funds or charging
a direct fee for servicing. If imposed, these fees would be in addition to any
amounts which might be paid to the Service Organization by the Funds. Each
Service Organization has agreed to transmit to its clients a schedule of any
such fees. Shareholders using Service Organizations are urged to consult them
regarding any such fees or conditions.

                        DETERMINATION OF NET ASSET VALUE

                  The net asset value of each Fund's shares will be determined
on any day that the New York Stock Exchange (the "NYSE") is open and, in the
case of the Money Market Funds, the Federal Reserve Bank are also open
("Business day"). The NYSE is closed on the following holidays: New Year's Day,
Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving and Christmas Day, and on the
preceding Friday or subsequent Monday when one of these holidays falls on a
Saturday or Sunday, respectively. In addition, the Federal Reserve Bank is
closed on Columbus Day and Veteran's Day.

                  The net asset value per share of each Fund is normally
determined daily as of the close of trading on the NYSE (generally 4:00 p.m.
Eastern time) on each business day of the Funds. In the event the NYSE closes
early (i.e. before 4:00 p.m. Eastern Time) on a particular day, the net asset
value of a Fund share is determined as of the close of the NYSE on such day. For
purposes of determining net asset value per share, futures and options contracts
closing prices which are available 15 minutes after the close of trading of the
NYSE will generally be used. Net asset value per share is determined by dividing
the value of the Fund's securities, cash and other assets (including interest
accrued but not collected), less all its liabilities (including accrued expenses
and dividends payable), by the total number of shares outstanding. Determination
of the Fund's net asset value per share is made in accordance with generally
accepted accounting principles.

                  Short-term investments that have a maturity of more than 60
days are valued at prices based on market quotations for securities of similar
type, yield and maturity. Short-


                                                                              39
<PAGE>   317
term investments that have a maturity of 60 days or less are valued at amortized
cost, which approximates fair value as determined by the Board of Trustees of
the Trust. Amortized cost involves valuing an instrument at its original cost to
the portfolio and thereafter assuming a constant amortization to maturity of any
discount or premium regardless of the effect of fluctuating interest rates on
the market value of the instrument.

                  Each equity security held by the Funds is valued at its last
sales price on the exchange where the security is principally traded or, lacking
any sales on a particular day, the security is valued at the closing bid price
on that day. Each security traded in the over-the-counter market (but not
including securities reported on the NASDAQ National Market System) is valued at
the mean between the last bid and asked prices based upon quotes furnished by
market makers for such securities. Each security reported on the NASDAQ National
Market System is valued at the last sales price on the valuation date or absent
a last sales price, at the closing bid price on that day. Debt securities are
valued on the basis of prices provided by an independent pricing service. Prices
provided by the pricing service may be determined without exclusive reliance on
quoted prices, and may reflect appropriate factors such as institution-size
trading in similar groups of securities, developments related to special
securities, yield, quality, coupon rate, maturity, type of issue, individual
trading characteristics and other market data. Securities for which market
quotations are not readily available are valued at fair value as determined in
good faith by or under the supervision of the Trust's officers in a manner
specifically authorized by the Board of Trustees of the Trust.

                  Generally, trading in foreign securities is substantially
completed each day at various times prior to the close of the NYSE. The values
of such foreign securities used in computing the net asset value of each Fund's
shares are determined at such times as trading is completed. Foreign currency
exchange rates are also generally determined prior the close of the NYSE.
Occasionally, events affecting the values of such foreign securities and such
foreign securities exchange rates may occur after the time at which such values
are determined and prior to the close of the NYSE that will not be reflected in
the computation of a Fund's net asset value. If events materially affecting the
value of such securities occur during such period, then these securities will be
valued at their fair value as determined in good faith by or under the
supervision of the Board of Trustees.

                  As indicated under "Pricing of Shares" in the prospectus, the
ING Money Market Funds use the amortized cost method to determine the value of
their portfolio securities pursuant to Rule 2a-7 under the 1940 Act. The
amortized cost method involves valuing a security at its cost and amortizing any
discount or premium over the period until maturity regardless of the impact of
fluctuating interest rates on the market value of the security. While this
method provides certainty in valuation, it may result in periods during which
the value, as determined by amortized cost, is higher or lower than the price
which a Fund would receive if the security were sold. During these periods, the
yield to a shareholder may differ somewhat from that which could be obtained
from a similar fund which utilizes a method of valuation based upon market
prices. Thus, during periods of declining interest rates, if the use of the
amortized cost method resulted in lower value of a Fund's portfolio on a
particular day, a prospective investor in the Fund would be able to obtain a
somewhat higher yield than would result from an investment in a fund utilizing
solely market values and existing Fund shareholders would receive
correspondingly less income. The converse would apply during periods of rising
interest rates.


                                                                              40
<PAGE>   318
                  Rule 2a-7 provides that in order to value its portfolio using
the amortized cost method, the ING Money Market Funds must maintain a
dollar-weighted average portfolio maturity of 90 days or less, purchase
securities having remaining maturities of 397 days or less and invest only in
U.S. dollar denominated eligible securities determined by the Trust's Board of
Trustees to be of minimal credit risks and which (1) have received the highest
short-term rating by at least two NRSROs (such as "A-1" by S&P and "P-1" by
Moody's); (2) are single rated and have received the highest short-term rating
by a NRSRO; or (3) are unrated, but are determined to be of comparable quality
by the Sub-Adviser.

                  In addition, the ING Money Market Funds will not invest more
than 5% of their total assets in the securities (including the securities
collateralizing a repurchase agreement) of a single issuer, except that, the
Funds may invest in U.S. Government securities or repurchase agreements that are
collateralized by U.S. Government securities without any such limitation. The
ING Money Market Funds may invest up to 25% of their total assets in the first
tier securities of a single issuer for a period of up to three business days
after the acquisition thereof provided that the Funds may not invest in the
securities of more than one issuer in accordance with this provision at any one
time.

                  Pursuant to Rule 2a-7, the Board of Trustees is also required
to establish procedures designed to stabilize, to the extent reasonably
possible, the price per share of the ING Money Market Funds, as computed for the
purpose of sales and redemptions, at $1.00. Such procedures include review of a
Fund's portfolio holdings by the Board of Trustees, at such intervals as it may
deem appropriate, to determine whether the net asset value of the Fund
calculated by using available market quotations deviates from $1.00 per share
based on amortized cost. The extent of any deviation will be examined by the
Board of Trustees. If such deviation exceeds 1/2 of 1%, the Board of Trustees
will promptly consider what action, if any, will be initiated. In the event the
Board of Trustees determines that a deviation exists which may result in
material dilution or other unfair results to investors or existing shareholders,
the Board of Trustees will take such corrective action as it regards as
necessary and appropriate, which may include selling portfolio instruments prior
to maturity to realize capital gains or losses or to shorten average portfolio
maturity, withholding dividends or establishing a net asset value per share by
using available market quotations.

                  Pursuant to procedures adopted by the Board of Trustees, the
fair value of a Wrapper Agreement ("Wrapper Value") entered into by the ING
Stable Value Fund generally will be equal to the difference between the "Book
Value" and the market value (plus accrued interest on the underlying securities)
of the portion of the Fund's assets covered by the Agreement ("Covered Assets").
Generally, the Book Value of the Covered Assets is their purchase price plus
interest on the Covered Assets accreted at a rate specified in the Wrapper
Agreement ("Crediting Rate"). The Crediting Rate used in computing Book Value is
calculated by a formula specified in the Wrapper Agreement and is adjusted
periodically. If the market value (plus accrued interest on the underlying
securities) of the Covered Assets is greater than their Book Value, the Wrapper
Value will be reflected as a liability of the Fund in the amount of the
difference, i.e., a negative value, reflecting the potential liability of the
Fund to the Wrapper Provider. If the market value (plus accrued interest on the
underlying securities) of the Covered Assets is less than their Book Value, the
Wrapper Value will be reflected as an asset of the Fund in the amount of the
difference, i.e., a positive value,


                                                                              41
<PAGE>   319
reflecting the potential liability of the Wrapper Provider to the Fund. In
performing its fair value determination, the Board expects to consider the
creditworthiness and ability of a Wrapper Provider to pay amounts due under the
Wrapper Agreement. If the Board determines that a Wrapper Provider is unable to
make such payments, that Board may assign a fair value to the Wrapper Agreement
that is less than the difference between the Book Value and the market value
(plus accrued interest on the underlying securities) of the applicable Covered
Assets and the Fund might be unable to maintain net asset value stability.

                         ADDITIONAL PURCHASE INFORMATION

                  Orders for the purchase of shares will be executed at the net
asset value per share plus any applicable initial sales loads (the "public
offering price") next determined after an order has been received. The minimum
initial investment in a Fund is $2,000 ($1,000 for an investment by an IRA or
any qualified retirement plan). Any subsequent investments must be at least $50,
including an IRA or qualified retirement plan investment. All initial
investments should be accompanied by a completed Account Application. An Account
Application accompanies the prospectus. A separate application is required for
an IRA or qualified retirement plan investor. All funds received are invested in
full and fractional shares of the appropriate Fund. Certificates for shares are
not issued. When you purchase shares of a Fund, please specify the class of
shares that you wish to purchase. If you do not choose a class of shares, then
your investment will be made in Class A shares. The Funds reserve the right to
reject any purchase order. All investments may be made using any of the
following methods described in the prospectus.

Description of Class A Shares

                  The public offering price of Class A shares is the net asset
value per share of the applicable Fund's shares plus any initial sales load. No
initial sales load is applied to Class A shares of the ING Stable Value Fund,
the Money Market Funds, or to Class A shares of any Fund that you purchase
through the reinvestment of dividends or distributions. The sales loads and
broker-dealer concessions, which vary with the size of the purchase, are set
forth in the prospectus.

                  Rights of Accumulation. The initial sales load for your
investment in Fund shares may be reduced by aggregating the amount of such
investment with the current value of all Fund shares currently owned by you at
the time of your current purchase. In order for the sales load reductions to be
effective under the Rights of Accumulation, the Transfer Agent must be notified
of the reduction request when the purchase order is placed. The Transfer Agent
may require evidence of your qualification for such reductions. Additional
information concerning the Rights of Accumulation can be obtained from the Funds
by calling 1-877-INFO-ING.

                  Letter of Intent ("LOI"). You may reduce the initial sales
load rate that applies to your purchases of Class A shares by meeting the terms
of an LOI -- a non-binding commitment to invest a certain amount within a
thirteen-month period from your initial purchase. The total amount of your
intended purchases of shares of the Funds will determine the reduced sales load
rate for Class A shares purchased during that period. This can include purchases
made up to 90 days before the date of the LOI. Of the LOI amount, 5% will be
held


                                                                              42
<PAGE>   320
in escrow to cover additional sales loads which may be due if your total
investments over the LOI period are not sufficient to qualify for a sales load
reduction. In order for the sales load reductions to be effective under the LOI,
the Transfer Agent must be notified of the reduction request when the purchase
order is placed. The Transfer Agent may require evidence of your qualification
for such reductions. Additional information concerning the LOI can be obtained
from the Funds by calling 1-877-INFO-ING.

                  Waiver of All Class A Shares Initial Sales Loads. No initial
sales load is imposed on sales of Class A shares for the following investors:
(i) the Manager, ING Group, any affiliate or direct or indirect subsidiary of
ING Group; (ii) present officers, directors, trustees and employees (and their
parents, spouses and dependent children) of the Funds, the Manager and its
affiliates (including ING Group and any affiliate or direct or indirect
subsidiary of ING Group), and any retirement plans established by such entities
for their employees; (iii) accounts with respect to which any person described
in (ii) above acts as a custodian on behalf of a minor (including Uniform Gift
to Minors Act and Uniform Transfer to Minors Act accounts); (iv) dealers that
have a sales agreement with the Distributor, if they purchase shares for their
own accounts or for retirement plans for their employees; (v) employees and
registered representatives (and their parents, spouses and dependent children)
of dealers or financial institutions that have entered into sales arrangements
with such dealers (and are identified to the Distributor) or with the
Distributor; the purchaser must certify to the Distributor at the time of
purchase that the purchase is for the purchaser's own account (or for the
benefit of such employee's parents, spouse, parents of spouse, or minor
children); (vi) dealers, brokers, registered investment advisers or third-party
administrators or consultants that have entered into an agreement with the
Distributor providing specifically for the use of Fund shares in investment
products or services made available to their clients (those clients may be
charged a transaction fee by their dealer, broker or adviser for the purchase or
sale of Fund shares); and (vii) employees (and their parents, spouses and
dependent children) of firms providing the Funds, the Trust or their affiliates
with regular legal, actuarial, underwriting, claims, administrative, computer
support, marketing, office or other services.

                  Additionally, no sales load is imposed on the following
transactions: (i) shares issued in plans of reorganization, such as mergers,
asset acquisitions and exchange offers, to which a Fund is a party; (ii) shares
purchased by the reinvestment of distributions received from a Fund; (iii)
shares purchased and paid for with the proceeds of shares redeemed in the prior
180 days from a mutual fund on which an initial sales load or CDSL was paid
(other than a mutual fund managed by the Manager or any of its affiliates); (iv)
purchases by a defined contribution plan under section 401(a) of the Code
(including 401(k) plans) with at least 25 eligible employees; (v) purchases by a
403(b)(7) or 457 plan subject to the Employee Retirement Income Security Act of
1974, as amended; (vi) shares purchased by the reinvestment of loan repayments
by a participant in a retirement plan; (vii) purchases by former participants in
a qualified retirement plan, where a portion of the plan was invested in the
Fund; (viii) purchases by non-qualified deferred compensation plans; and (ix)
purchases under arrangements between the Distributor and organizations which
make recommendations to or permit group solicitations of its employees, members
or participants.

                  In order for the above sales load waivers to be effective, the
Transfer Agent must be notified of the waiver request when the purchase order is
placed. The Transfer Agent may require evidence of your qualification for such
waivers. Additional information about the


                                                                              43
<PAGE>   321
above sales load waivers can be obtained from the Funds by calling
1-877-INFO-ING.

                  Contingent Deferred Sales Load. The redemption proceeds of
Class A shares that were not at the time of purchase assessed an initial sales
load because the investor purchased $1,000,000 or more of such shares (including
shares acquired under Right of Accumulation and LOI), will be assessed a CDSL if
such shares are redeemed within twelve months after their purchase date (the
"CDSL Period"). The Class A CDSL will be assessed on the lesser of the net asset
value of the shares at the time of redemption or at the time of purchase. The
Class A CDSL will not be imposed on the amount of any increase in your account
value over the initial amount invested. To determine whether the Class A CDSL
applies to a redemption, the Fund redeems shares in the following order: (i)
shares acquired by reinvestment of dividends and capital gains distributions;
(ii) shares held for over one year; and (iii) shares in the order they were
purchased (such that shares held the longest are redeemed first). The Class A
CDSL does not apply to the ING Stable Value Fund or to the Money Market Funds.

                  Waiver of Class A CDSL. The Class A CDSL for purchases
aggregating $1 million or more will be waived in the following cases if shares
are redeemed and the Transfer Agent is notified prior to the redemption: (i)
redemption of shares by an investor who would otherwise qualify for an
exemption, described above, from the initial sales load (i.e., employees of the
Manager, etc.); (ii) redemption of shares when a Fund exercises its right to
liquidate accounts which are less than the minimum account size; (iii)
redemption to pay for optional insurance coverage described in the Prospectus
under "Redemption Plans -- Optional Benefit"; (iv) the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code (if satisfactory evidence
is provided to the Fund); (v) the portion of a mandated minimum distribution
from an IRA, Simple IRA or an individual type 403(b)(7) plan equal to the
percentage of your plan assets held in Class A shares of the Funds; (vi)
reinvested dividends and capital gains and (vii) a Systematic Withdrawal Plan of
10% per year where the minimum distribution is $500 per month.

                  In order for the CDSL waivers to be effective, the Transfer
Agent must be notified of the waiver request when the redemption order is
placed. The Transfer Agent may require evidence of your qualification for such
waivers. Additional information about the above CDSL waivers can be obtained
from the Funds by calling 1-877-INFO-ING.

Description of Class B Shares

                  The public offering price of Class B shares is the net asset
value of the applicable Fund's shares. Such shares are sold without an initial
sales load so that the Fund receives the full amount of the investor's purchase.
However, a CDSL will be imposed if shares are redeemed within six years of
purchase (except for the ING Stable Value Fund). The Class B CDSL will not apply
to redemptions of shares purchased by the reinvestment of dividends or capital
gains distributions and may be waived under certain circumstances described
below. The Class B CDSL will be assessed on the lesser of the net asset value of
the shares at the time of redemption or at the time of purchase. The Class B
CDSL will not be imposed on the amount of any increase in your account value
over the initial amount invested. The Class B CDSL is paid to the Distributor to
reimburse expenses incurred in providing distribution-related services to the
Funds in connection with the sale of Class B shares.


                                                                              44
<PAGE>   322
Although Class B shares are sold without an initial sales load, the Distributor
normally pays a sales commission of 4.00% of the purchase price of Class B
shares to the dealer from its own resources at the time of the sale. The
Distributor, ING Fund Services and their agents may assign their right to
receive any Class B CDSL, certain distribution, shareholder servicing and
account servicing fees to an entity affiliated with the Manager that provides
funding for up-front sales commission payments.

                  To determine whether the Class B CDSL applies to a redemption,
the Fund redeems shares in the following order: (i) shares acquired by
reinvestment of dividends and capital gains distributions; (ii) shares held for
over six years; and (iii) shares in the order they were purchased (such that
shares held the longest are redeemed first). The amount of the Class B CDSL will
depend on the number of years since the time you invested and the dollar amount
being redeemed, according to the following schedule:

                6th year after purchase                    1%
</TABLE>

                  In the table, a "year" is a 12-month period. All purchases are
considered to have been made on the business day of the month in which the
purchase was made.

                  Waiver of Class B CDSL. The Class B CDSL will be waived in the
following cases if shares are redeemed and the Transfer Agent is notified: (i)
redemption of shares when a Fund exercises its right to liquidate accounts which
are less than the minimum account size; (ii) redemption to pay for optional
insurance coverage described in the prospectus under "How to Redeem Shares";
(iii) the death or post-purchase disability, as defined in Section 72(m)(7) of
the Code (if satisfactory evidence is provided to the Funds); (iv) the portion
of a mandated minimum distribution from an IRA, Simple IRA or an individual type
403(b)(7) plan equal to the percentage of your plan assets held in Class B
shares of the Funds; (v) reinvested dividends and capital gains and (vi) a
Systematic Withdrawal Plan of 10% per year where the minimum distribution is
$500 per month with an initial account of $20,000 or greater.

                  Conversion to Class A Shares. Eight years after you purchase
Class B shares of a Fund, those shares will automatically convert to Class A
shares of that Fund (except for the ING Stable Value Fund). This conversion
feature relieves Class B shareholders of the higher asset-based distribution
charges that applies to these shares. The conversion is based on the relative
net asset value, and no sales load or other charge is imposed. At the time of
conversion, a portion of the Class B shares purchased through the reinvestment
of dividends or capital gains ("Dividend Shares") will also convert to Class A
shares. The portion of Dividend Shares that will convert is determined by the
ratio of your converting Class B non-Dividend Shares to your total Class B
non-Dividend Shares. Under Section 1036 of the Code, the automatic conversion of
Class B shares will not result in a gain or loss to the Fund or to affected
shareholders.


                                                                              45
<PAGE>   323
Description of Class C Shares

                  The public offering price of Class C shares is the net asset
value of such shares. Class C shares are sold without an initial sales load so
that the applicable Fund receives the full amount of the investor's purchase.
While Class C shares do not convert to Class A shares, they are subject to a
lower CDSL (1.00%) and do not have to be held for as long a time (one year) as
Class B shares to avoid paying a CDSL. The Class C CDSL will be assessed on the
lesser of the net asset value of the shares at the time of redemption or at the
time of purchase. The Class C CDSL will not be imposed on the amount of any
increase in your account value over the initial amount invested. To determine
whether the Class C CDSL applies to a redemption, the Fund redeems shares in the
following order: (i) shares acquired by reinvestment of dividends and capital
gains distributions; (ii) shares held for over one year; and (iii) shares in the
order they were purchased (such that shares held the longest are redeemed
first). Class C shares do not convert to Class A shares.

                  Proceeds from the CDSL are paid to the Distributor and are
used to defray its expenses related to providing distribution-related services
to the applicable Fund in connection with the sale of Class C shares, such as
the payment of compensation to selected broker-dealers, and for selling Class C
shares. The combination of the CDSL and the Rule 12b-1 fee enables the Fund to
sell the Class C shares without deduction of a sales load at the time of
purchase. Although Class C shares are sold without an initial sales load, the
Distributor pays a dealer concession equal to 1.00% of the amount invested to
broker-dealers who sell Class C shares at the time the shares are sold.

                  Waiver of Class C CDSL. The Class C CDSL will be waived in the
following cases if shares are redeemed and the Transfer Agent is notified: (i)
redemption of shares when a Fund exercises its right to liquidate accounts which
are less than the minimum account size; (ii) redemption to pay for optional
insurance coverage described in the Prospectus under "How to Redeem Shares";
(iii) the death or post-purchase disability, as defined in Section 72(m)(7) of
the Code (if satisfactory evidence is provided to the Funds); (iv) the portion
of a mandated minimum distribution from an IRA, Simple IRA or an individual type
403(b)(7) plan equal to the percentage of your plan assets held in Class C
shares of the Funds; (v) reinvested dividends and capital gains and (vi) a
Systematic Withdrawal Plan of 10% per year where the minimum distribution is
$500 per month with an initial account of $20,000 or greater.

Description of Class X Shares

                  Class X shares are currently offered to certain "Qualified"
purchases (including, but not limited to, IRAs, Education IRAs, SEP IRAs, Simple
IRAs and 403(b)(7) plans). Any request for "Non-Qualified" purchases of Class X
shares up to $1,000,000 will normally be considered as a purchase request for
Class B shares or declined. Any request for "Non-Qualified" purchases of Class X
shares for $1,000,000 or more will be considered as a purchase request for Class
A shares or declined, because it is more advantageous for an investor to
purchase Class A shares for such amounts.

                  The public offering price of Class X shares is the net asset
value of the applicable Fund's shares. In addition, investors purchasing Class X
shares will receive, as a bonus, additional shares ("Bonus Shares") having a
value equal to 2.00% of the amount


                                                                              46
<PAGE>   324
invested. The Distributor has undertaken to pay for Bonus Shares as part of its
services to the Funds. The Distributor expects to recover costs associated with
its purchases of Bonus Shares through fees received under the Class X
Distribution Plan. Shares purchased by the reinvestment of dividends or capital
gains distributions are not eligible for Bonus Shares.

                  Although Class X shares are sold without an initial sales
load, a CDSL will be imposed if shares are redeemed within six years of
purchase. The Class X CDSL will not apply to redemptions of Bonus Shares or
shares purchased by the reinvestment of dividends or capital gains distributions
and may be waived under certain circumstances described below. The Class X CDSL
will be assessed on the lesser of the net asset value of the shares at the time
of redemption or at the time of purchase. The Class X CDSL will not be imposed
on the amount of any increase in your account value over the amount invested.
The Class X CDSL is paid to the Distributor to reimburse expenses incurred in
providing distribution-related services to the Fund in connection with the sale
of Class X shares. Although Class X shares are sold without an initial sales
load, the Distributor normally pays a sales commission of 2.50% of the purchase
price of Class X shares to the dealer from its own resources at the time of the
sale. The Distributor, ING Fund Services and their agents may assign their right
to receive any Class X CDSL, certain distribution, shareholder servicing and
account servicing fees to an entity affiliated with the Manager that provides
funding for up-front sales commission payments.

                  To determine whether the Class X CDSL applies to a redemption,
the Fund redeems shares in the following order: (i) shares acquired by
reinvestment of dividends and capital gains distributions; (ii) shares
(including Bonus Shares) held for over six years; and (iii) shares (not
including Bonus Shares) in the order they were purchased (such that shares held
the longest are redeemed first); and (iv) Bonus Shares in the order they were
acquired (such that Bonus Shares held the longest are redeemed first). The
amount of the Class X CDSL will depend on the number of years since the time you
invested and the dollar amount being redeemed, according to the following
schedule:

                  In the table, a "year" is a 12-month period. All purchases are
considered to have been made on the business day of the month in which the
purchase was made.

                  Waiver of Class X CDSL. The Class X CDSL will be waived in the
following cases if shares are redeemed and the Transfer Agent is notified: (i)
redemption of shares when a Fund exercises its right to liquidate accounts which
are less than the minimum account size; (ii) the death or post-purchase
disability, as defined in Section 72(m)(7) of the Code (if satisfactory evidence
is provided to the Fund); (iii) the portion of a mandated minimum distribution
from an IRA, Simple IRA or an individual type 403(b)(7) plan equal to the
percentage of your plan assets held in Class X shares of the Fund; and (iv)
reinvested dividends and capital gains.


                                                                              47

                  Conversion to Class A Shares. Eight years after you purchase
Class X shares of a Fund, those shares will automatically convert to Class A
shares of that Fund. This conversion feature relieves Class X shareholders of
the higher asset-based distribution charges that apply to these shares. The
conversion is based on the relative net asset value, and no sales load or other
charge is imposed. At the time of conversion, a portion of the Class X shares
purchased through the reinvestment of dividends or capital gains ("Dividend
Shares") will also convert to Class A shares. The portion of Dividend Shares
that will convert is determined by the ratio of your converting Class X
non-Dividend Shares to your total Class X non-Dividend Shares. Under Section
1036 of the Code, the automatic conversion of Class X shares will not result in
a gain or loss to the Fund or to affected shareholders.

Description of Class I Shares

                  Class I shares are currently offered only to retirement plans
affiliated with ING Group. The public offering price of Class I shares is the
net asset value of the applicable Fund's shares.

Minimum Account Balance

                  If (i) an account opened in a Fund has been in effect for at
least one year and the shareholder has not made an additional purchase in that
account within the preceding six calendar months and (ii) the value of such
account drops below $500 for three consecutive months as a result of redemptions
or exchanges, the Fund has the right to redeem the account, after giving the
shareholder 60 days' prior written notice, unless the shareholder makes
additional investments within the notice period to bring the account value up to
$500. If a Fund determines that a shareholder has provided incorrect information
in opening an account with a Fund or in the course of conducting subsequent
transactions with the Fund related to such account, the Fund may, in its
discretion, redeem the account and distribute the proceeds of such redemption to
the shareholder.

Reinstatement Privilege

                  Within 90 days of a redemption, a shareholder may invest all
or part of the redemption proceeds of shares in the same class of shares of any
Fund at the public offering price next computed after receipt by the Transfer
Agent of the funds to be reinvested. You will receive a credit for any initial
sales charge or CDSL previously paid. The shareholder must ask the Transfer
Agent for such privilege at the time of reinvestment. A realized gain on the
redemption is taxable, and reinvestment may alter any capital gains payable. If
there has been a loss on the redemption and shares of the same fund are
repurchased, all of the loss may not be tax deductible, depending on the timing
and amount reinvested. Under the Code, if the redemption proceeds of Fund shares
on which a sales load was paid are reinvested in (or exchanged for) shares of
another Fund at a reduced sales load within 90 days of the payment of the sales
load, the shareholder's basis in the fund shares redeemed may not include the
amount of the sales load paid, thereby reducing the loss or increasing the gain
recognized from the redemption; however, the shareholder's basis in the Fund
shares purchased will include the sales load. Each Fund may amend, suspend or
cease offering this privilege at any time as to shares redeemed after the date
of such amendment, suspension or cessation. This privilege


                                                                              48
<PAGE>   326
may only be exercised once each year by a shareholder with respect to each Fund.


                       ADDITIONAL REDEMPTION INFORMATION

                  Shareholders may redeem their shares, in whole or in part, on
each day a Fund is valued. Shares will be redeemed without charge (except any
applicable CDSL) at the net asset value next determined after a redemption
request in good order has been received by the applicable Fund. In the instance
where a shareholder owns more than one class of shares and the shares being
redeemed are not subject to the CDSC, those shares with the highest Rule 12b-1
fee will be redeemed in full prior to any redemption of shares with a lower Rule
12b-1 fee.

                  Where purchases are made by check in any Fund, redemption
proceeds will be made available immediately upon clearance of the purchase
check, which may take up to 15 calendar days. Shareholders may avoid this delay
by investing through wire transfers of federal funds. During the period prior to
the time the shares are redeemed, dividends on the shares will continue to
accrue and be payable and the shareholder will be entitled to exercise all other
beneficial rights of ownership.

                  Once the shares are redeemed, a Fund will ordinarily send the
proceeds by check to the shareholder at the address of record on the next
business day. The Funds may, however, take up to seven days to make payment.
This will not be the customary practice. Also, if the New York Stock Exchange is
closed (or when trading is restricted) for any reason other than the customary
weekend or holiday closing or if an emergency condition as determined by the SEC
merits such action, the Funds may suspend redemptions or postpone payment dates.
No interest or additional dividends will be earned on amounts represented by
uncashed redemption checks or misapplied wire payments.

                  To ensure acceptance of your redemption request, it is
important to follow the procedures described below. Although the Funds have no
present intention to do so, the Funds reserve the right to refuse or to limit
the frequency of any telephone or wire redemptions. Of course, it may be
difficult to place orders by telephone during periods of severe market or
economic change, and a shareholder should consider alternative methods of
communications, such as couriers. The Funds may modify or terminate their
services and provisions at any time. If the Funds terminate any particular
service, they will do so only after giving written notice to shareholders.
Redemption by mail will always be available to shareholders. Under certain
circumstances described below, a signature guarantee may be required. You may
redeem your shares using any of the methods described in the prospectus.

Redemption Fees

                  The ING Stable Value Fund charges a redemption fee under
certain conditions to discourage redemptions initiated by shareholders
attempting to take advantage of interest rate movements. The ING Stable Value
Fund will deduct a 2.00% redemption fee pursuant to the terms outlined in the
Prospectus.


                                                                              49
<PAGE>   327
Signature Guarantees

                  A signature guarantee is designed to protect the investor, the
Funds, the Distributor, and their agents by verifying the signature of each
investor seeking to redeem, transfer, or exchange shares of the Funds. Signature
guarantees are required for: (i) redemptions by mail in excess of $50,000; (ii)
redemptions by mail if the proceeds are to be paid to someone other than the
name(s) in which the account is registered; (iii) written redemptions requesting
proceeds to be sent by wire to other than the bank of record for the account;
(iv) redemptions requesting proceeds to be sent to a new address or an address
that has been changed within the past 15 days; (v) requests to transfer the
registration of shares to another owner; (vi) telephone exchange and telephone
redemption authorization forms; (vii) changes in previously designated wiring
instructions; and (viii) written redemptions or exchanges of shares previously
reported as lost/abandoned property, whether or not the redemption amount is
under $50,000 or the proceeds are to be sent to the address of record. These
requirements may be waived or modified upon notice to shareholders.

                  Acceptable guarantors include banks, broker-dealers, credit
unions, national securities exchanges, savings associations and any other
organization, provided that such institution or organization qualifies as an
"eligible guarantor institution" as that term is defined in rules adopted by the
SEC, and further provided that such guarantor institution is listed in one of
the reference guides contained in the Transfer Agent's current Signature
Guarantee Standards and Procedures, such as certain domestic banks, credit
unions, securities dealers, or securities exchanges. The Transfer Agent will
also accept signatures with either: (i) a signature guarantee with a medallion
stamp of the STAMP Program, or (ii) a signature guaranteed with a medallion
stamp of the NYSE Medallion Signature Program, provided that in either event,
the amount of the transaction involved does not exceed the surety coverage
amount indicated on the medallion. For information regarding whether a
particular institution or organization qualifies as an "eligible guarantor
institution," an investor should call the Funds at 1-877-INFO-ING.

Redemption in Kind

                  All redemptions of shares of the Funds shall be made in cash,
except that the commitment to redeem shares in cash extends only to redemption
requests made by each shareholder of a Fund during any 90-day period of up to
the lesser of $250,000 or 1% of the net asset value of that Fund at the
beginning of such period. This commitment is irrevocable without the prior
approval of the SEC and is a fundamental policy of the Funds that may not be
changed without shareholder approval. In the case of redemption requests by
shareholders in excess of such amounts, the Board of Trustees reserves the right
to have the Funds make payment, in whole or in part, in securities or other
assets, including, in the case of the ING Stable Value Fund, Wrapper Agreements,
in case of an emergency or any time a cash distribution would impair the
liquidity of a Fund to the detriment of the existing shareholders. In this
event, the securities would be valued in the same manner as the securities of
that Fund are valued. If the recipient were to sell such securities he or she
may receive more or less than the value of such securities as determined above,
and might incur brokerage charges.


                                                                              50
<PAGE>   328
                  The ING Stable Value Fund. To the extent that any payment in
kind by the ING Stable Value Fund includes a Wrapper Agreement, the Fund will
assign a portion of one or more Wrapper Agreements to you. The economic terms
and conditions of each assigned Wrapper Agreement will be substantially similar
to the Wrapper Agreements held by the Fund.

                  To accept the assignment of a Wrapper Agreement, you must, in
a writing delivered to us, accept such assignment and represent to the Wrap
Provider that such assignment and acceptance of the Wrapper Agreement does not
violate any laws applicable to you. In that regard, you may be required to
retain the services of a qualified professional asset manager ("QPAM") to review
and make the decision to accept the assignment on your behalf. In the event you
do not accept the assignment of the Wrapper Agreement, you may either receive
Securities as a payment in kind, or elect to provide the Fund with twelve (12)
months notice of your request for such redemption. The Fund may require
prospective shareholders to agree, prior to investing in the Fund, that they
will accept an assignment of a Wrapper Agreement as part of an in kind
redemption, provided that at the time of the redemption payment such assignment
would not violate applicable law.

                  To the extent a payment in kind is made with securities, you
may incur transaction expenses in custodying and disposing of the securities.
Therefore, a shareholder receiving securities will likely incur costs that may
exceed such shareholder's share of the operating expenses incurred by the Fund.
In addition, Wrapper Agreements assigned to you as a payment in kind are
illiquid and will require you to pay fees directly to the Wrap Provider rather
than through the Fund. Further, the Wrapper Agreement may contain restrictions
on the securities subject to such agreement, including, but not limited to, the
types, maturities, duration and credit quality of each security. Therefore, to
obtain the benefits of a Wrapper Agreement, you may not be able to freely trade
the securities underlying the agreement. Finally, if you obtain the services of
a QPAM in connection with a payment in kind, you will incur additional costs.

                  In the event a redemption is made in kind with a Wrapper
Agreement, the Fund will incur costs in obtaining such Wrapper Agreement. These
costs are not expected to exceed the redemption fee.

                          PURCHASE AND REDEMPTION PLANS

                  The Trust offers various purchase and redemption plans that
make investing and redeeming shares of the Funds more convenient than by mail or
wire. The following are the plans offered and the features of the plans. Please
contact the Funds at 1-877-INFO-ING for the appropriate authorization form.
These purchase and redemption plans are currently not available for investors
that invest through IRAs or any qualified retirement plans.

                  ING Auto-Asset Accumulation Plan. This plan permits you to
purchase Fund shares (minimum of $50 per transaction) at regular intervals
selected by you. Fund shares are purchased by transferring funds from the bank
account designated by you. Only an account maintained at a domestic financial
institution which is an Automated Clearing House member


                                                                              51
<PAGE>   329
may be so designated. To establish an Auto-Asset Accumulation Plan account, you
must file an authorization form with the Transfer Agent. You may obtain the
necessary authorization form from the Funds by calling 1-877-INFO-ING. You may
cancel your participation in this privilege or change the amount of purchase at
any time by mailing written notification to ING Funds, P.O. Box 419416, Kansas
City, MO 64141-6416, and the notification will be effective three business days
following receipt. The Fund may modify or terminate this privilege at any time
or charge a service fee. No such fee currently is contemplated.

                  ING Directed Federal Deposit Plan. ING Directed Federal
Deposit Plan enables you to purchase Fund shares (minimum of $50 per
transaction) by having Federal salary, Social Security, or certain veterans',
military or other payments from the federal government automatically deposited
into your Fund account. You may deposit as much of such payments as you elect.
To enroll in this plan you must file with the Transfer Agent a completed
Directed Deposit Sign-Up Form for each type of payment that you desire to
include in this plan. The appropriate form may be obtained from the Funds by
calling 1-877-INFO-ING. Death or legal incapacity will terminate your
participation in this plan. You may elect at any time to terminate your
participation by notifying in writing the appropriate federal agency. The Fund
may terminate your participation upon 30 days' notice to you.

                  ING Scheduled Payroll Investment Program. ING Scheduled
Payroll Investment Program permits you to purchase Fund shares automatically on
a regular basis. Depending upon your employer's direct deposit program, you may
have part or all of your paycheck transferred to your existing ING account
electronically through the Automated Clearing House system at each pay period.
To establish an ING Scheduled Payroll Investment Program account, you must file
an authorization form with your employer's payroll department. Your employer
must complete the reverse side of the form and return it to ING Funds, P.O. Box
419416, Kansas City, MO 64141-6416. You may obtain the necessary authorization
form from the Funds by calling 1-877-INFO-ING. You may change the amount of
purchase or cancel the authorization only by written notification to your
employer. It is the sole responsibility of your employer, not the Distributor,
the Trust, the Transfer Agent or any other person, to arrange for transactions
under the ING Scheduled Payroll Investment Program. Minimum investment amounts
will be determined on a case-by-case basis. The Fund may modify or terminate
this program at any time or charge a service fee. No such fee currently is
contemplated.

                  Systematic Withdrawal Plan. An owner whose initial account
balance equaled $20,000 or more of a Fund may elect to have periodic redemptions
of up to 10% per year of the initial account balance from his or her account to
be paid on a monthly, quarterly, semi-annual or annual basis. The minimum
periodic payment is $50. A sufficient number of shares to make the scheduled
redemption will normally be processed on the selected day of the selected
month(s). Depending on the size of the payment requested and fluctuation in the
net asset value, if any, of the shares redeemed, redemptions for the purpose of
making such payments may reduce or even exhaust the account. A shareholder may
request that these payments be sent to a predesignated bank or other designated
party. Capital gains and dividend distributions paid to the account will
automatically be reinvested at net asset value on the distribution payment date.

redemption proceeds (minimum $500 per day) be transferred between your Fund
account and your bank account. Only a bank account maintained in a domestic
financial institution which is an Automated Clearing House member may be
designated. Redemption proceeds will be on deposit in your account at an
Automated Clearing House member bank ordinarily two days after receipt of the
redemption request. Holders of jointly registered Fund or bank accounts may
redeem through the plan for transfer to their bank account not more than
$250,000 within any 30-day period.

                  Optional Benefit. ING Group, an affiliate of ING Group, or an
unrelated third party (the "Insurer") may make certain life insurance coverage
available to certain persons on whose behalf shares of the Funds are purchased.
The benefits of this coverage payable at death will be related to the amounts
paid to purchase shares and to the value of the shares held for the benefit of
the insured persons. Therefore, coverage will terminate if all shares are
redeemed.

                  Purchasers of the life insurance coverage will be required to
authorize periodic redemptions of Fund shares to pay the premiums for such
coverage. Such redemptions will not be subject to CDSLs, but will have the same
tax consequences as any other Fund redemptions.

                  This life insurance coverage will be available to eligible
persons who enroll for the coverage within a limited time period after shares in
any Fund are initially purchased or transferred. In addition, coverage cannot be
made available unless the Insurer knows for whose benefit shares are purchased.
For instance, coverage cannot be made available for shares registered in the
name of your broker unless the broker provides the Insurer with information
regarding the beneficial owners of such shares. Other restrictions on the
coverage will apply, such as the age of the persons upon whose life the coverage
is issued. This insurance coverage may not be available in all states and may be
subject to additional restrictions or limitations on coverage. Purchasers of
shares should also make themselves familiar with the impact on the life coverage
of purchasing additional shares, reinvestment of dividends and capital gains
distributions and redemptions. Please call 1-877-INFO-ING for more information
and application forms for this program.

                           BROKER-DEALER COMPENSATION

                  As discussed in the prospectus, a broker-dealer may receive
different levels of compensation depending on which class of shares is sold. The
Distributor may also provide, from its own resources and not from the resources
of the Funds, additional compensation to broker-dealers in connection with
selling shares of the Funds or for the broker-dealer's own company-sponsored
sales programs. This additional compensation may take the form of additional
payments by the Distributor or a reallowance by the Distributor of up to the
full applicable initial sales load. A broker-dealer who receives a reallowance
of the full applicable initial sales load may be deemed an "underwriter" under
the Securities Act of 1933 Act, as amended, during such periods.

                  The following are broker dealers who are currently
participating in the reallowance program: Merit Capital Associates, Inc. and
Princeton Securities Corporation. Such programs may be extended for a limited
time or may continue until terminated by the Distributor.


                                                                              53
<PAGE>   331
                  The Distributor may provide up to 1.00% to dealers of record
for shares purchased without a sales load when shares purchased and paid for
with the proceeds of shares redeemed in the prior 180 days from a mutual fund on
which an initial sales load or CDSL was paid (other than a mutual fund managed
by the Manager or any of its affiliates).

                  The Distributor may pay individual representatives of
affiliated companies up to an additional 1.00% of the net asset value of Class
A, Class B, Class C, Class X and/or Class I shares of the Funds sold by such
persons. The affiliated companies, as such term is defined under the 1940 Act,
are IFG Network Securities, Inc., Locust Street Securities, Inc.,
Multi-Financial Securities Corporation, Vestax Securities Corp., Southland Life
Insurance Company, Security Life of Denver Insurance Company, Equitable Life
Insurance Company of Iowa, and Compulife Investor Services, Inc. Representatives
of the affiliated companies also may receive up to .20% of the net asset value
of Class A, Class B, Class C and Class X shares of the Funds sold by them.

                  For selected periods of time, the Distributor has undertaken
to pay (i) 2.00% of the net asset value of Class A, Class B, Class C and Class X
shares of the Funds sold (other than the ING Money Market Funds), including
sales and transfers at net asset value to Cantella & Co., Inc.; (ii) .25% of the
net asset value of Class A, Class B, Class C and Class X shares of the Funds
sold (other than the ING Money Market Funds), including sales and transfers at
net asset value to Dain Rauscher Incorporated; and (iii) .20% of the net asset
value of Class A, Class B, Class C and Class X shares of the Funds sold (other
than the ING Money Market Funds), including sales and transfers at net asset
value to Advest, Inc. Such programs may be extended for a limited time or may
continue until terminated by the Distributor.

                             PORTFOLIO TRANSACTIONS

                  Investment decisions for the Funds and for the other
investment advisory clients of the Sub-Adviser are made with a view to achieving
their respective investment objectives. Investment decisions are the product of
many factors in addition to basic suitability for the particular client
involved. Thus, a particular security may be bought or sold for certain clients
even though it could have been bought or sold for other clients at the same
time. Likewise, a particular security may be bought for one or more clients when
one or more clients are selling the security. In some instances, one client may
sell a particular security to another client. It also sometimes happens that two
or more clients simultaneously purchase or sell the same security, in which
event each day's transactions in such security are, insofar as possible,
averaged as to price and allocated between such clients in a manner which in the
Sub-Adviser's opinion is equitable to each and in accordance with the amount
being purchased or sold by each. There may be circumstances when purchases or
sales of portfolio securities for one or more clients will have an adverse
effect on other clients.

                  The Funds have no obligation to deal with any dealer or group
of dealers in the execution of transactions in portfolio securities. Subject to
policies established by the Funds' Boards of Trustees, the Sub-Adviser is
primarily responsible for portfolio decisions and the placing of portfolio
transactions. In placing orders, it is the policy of the Funds to obtain the
best results taking into account the broker-dealer's general execution and
operational facilities, the type of transaction involved and other factors such
as the dealer's risk in positioning the


                                                                              54
<PAGE>   332
securities. While the Sub-Adviser generally seeks reasonably competitive spreads
or commissions, the Funds will not necessarily be paying the lowest spread or
commission available. The reasonableness of such spreads or brokerage
commissions will be evaluated by comparing spreads or commissions among brokers
or dealers in consideration of the factors listed immediately above and research
services described below.

                  Purchases and sales of securities will often be principal
transactions in the case of debt securities and equity securities traded
otherwise than on an exchange. The purchase or sale of equity securities will
frequently involve the payment of a commission to a broker-dealer who effects
the transaction on behalf of a Fund. Debt securities normally will be purchased
or sold from or to issuers directly or to dealers serving as market makers for
the securities at a net price. Generally, money market securities are traded on
a net basis and do not involve brokerage commissions. Under the 1940 Act,
persons affiliated with the Funds or the Distributor are prohibited from dealing
with the Funds as a principal in the purchase and sale of securities except in
limited situations permitted by SEC regulations, unless an exemptive order
allowing such transactions is obtained from the SEC.

                  The aggregate amount of brokerage commissions paid by the
Funds during the fiscal year ended October 31, 1999 were:

                  The Sub-Adviser may, in circumstances in which two or more
broker-dealers are in a position to offer comparable results, give preference to
a dealer which has provided statistical or other research services to the
Sub-Adviser. By allocating transactions in this manner, the Sub-Adviser is able
to supplement its research and analysis with the views and information of
securities firms. These items, which in some cases may also be purchased for
cash, include such matters as general economic and security market reviews,
industry and company reviews, evaluations of securities and recommendations as
to the purchase and sale of securities. Some of these services are of value to
the Sub-Adviser in advising various of its clients (including the Funds),
although not all of these services are necessarily useful and of value in
managing the Funds. The management fee paid by the Funds is not reduced because
the Sub-Adviser and its affiliates receive such services.


                                                                              55
<PAGE>   333
                  As permitted by Section 28(e) of the Securities Exchange Act
of 1934 (the "1934 Act"), the Sub-Adviser may cause the Funds to pay a
broker-dealer which provides "brokerage and research services" (as defined in
the 1934 Act) to the Sub-Adviser an amount of disclosed commission for effecting
a securities transaction for the Funds in excess of the commission which another
broker-dealer would have charged for effecting that transaction.

                  The Sub-Adviser may allocate purchase and sales orders for
portfolio securities to broker-dealers that are affiliated with the Manager or
the Distributor in agency transactions, if the Sub-Adviser believes the quality
of the transaction and commissions are comparable to what they would be with
other qualified brokerage firms.

                  Consistent with the Rules of Fair Practice of the National
Association of Securities Dealers, Inc. and subject to seeking the most
favorable price and execution available and such other policies as the Trustees
may determine, the Sub-Adviser may consider sales of shares of the Funds as a
factor in the selection of broker-dealers to execute portfolio transactions for
the Funds.


Portfolio Turnover

                  Changes may be made in the portfolio consistent with the
investment objectives and policies of the Funds whenever such changes are
believed to be in the best interests of the Funds and their shareholders.
Portfolio turnover rate is, in general, the percentage computed by taking the
lesser of purchases or sales of portfolio securities (excluding securities with
a maturity date of one year or less at the time of acquisition) for the period
and dividing it by the monthly average of the market value of such securities
during the period. For purposes of this calculation, portfolio securities
exclude all securities having a maturity when purchased of one year or less.

                                    TAXATION

                  Each Fund intends to qualify and elect annually to be treated
as a regulated investment company under Subchapter M of the Internal Revenue
Code of 1986, as amended (the "Code"). To qualify as a regulated investment
company, a Fund must (a) distribute to shareholders at least 90% of its
investment company taxable income (which includes, among other items, dividends,
taxable interest and the excess of net short-term capital gains over net
long-term capital losses); (b) derive in each taxable year at least 90% of its
gross income from dividends, interest, payments with respect to securities loans
and gains from the sale or other disposition of stock, securities or foreign
currencies or other income derived with respect to its business of investing in
such stock, securities or currencies; and (c) diversify its holdings so that, at
the end of each quarter of the taxable year, (i) at least 50% of the market
value of the Fund's assets is represented by cash and cash items (including
receivables), U.S. Government securities, the securities of other regulated
investment companies and other securities, with such other securities of any one
issuer limited for the purposes of this calculation to an amount not greater
than 5% of the value of the Fund's total assets and not greater than 10% of the
outstanding voting securities of such issuer, and (ii) not more than 25% of the
value of its total assets is invested in the securities of any one issuer (other
than U.S. Government securities or


                                                                              56
<PAGE>   334
the securities of other regulated investment companies). In addition, a Fund
earning tax-exempt interest must, in each year, distribute at least 90% of its
net tax-exempt income. By meeting these requirements, the Funds generally will
not be subject to federal income tax on its investment company taxable income
and net capital gains which are distributed to shareholders. If the Funds do not
meet all of these Code requirements, they will be taxed as ordinary corporations
and their distributions will be taxed to shareholders as ordinary income.

                  As long as the Funds qualify as regulated investment companies
for federal income tax purposes, each Fund, in computing its income subject to
federal income tax, is entitled to deduct all dividends other than
"preferential" dividends paid by it to shareholders during the taxable year.
"Preferential" dividends are dividends other than dividends which have been
distributed to shareholders pro rata without preference to any share of the Fund
as compared with other shares of the same class and without preference to one
class of shares as compared with another, except in accordance with the former's
dividend rights as a class. The Funds believe that a multiple-class structure
having all of the features of the multiple-class structure of each of the Funds
would not result in dividends being treated as "preferential." The Funds' belief
is not binding on the Internal Revenue Service (the "IRS"), no ruling has been
obtained by the Funds from the IRS on the matter and there can be no guarantee
that the IRS will agree with the Funds on this matter. The Funds' belief is
based on the application of current federal income tax law and relevant
authorities, and subsequent changes in federal tax law or judicial or
administrative decisions or pronouncements may supercede or affect the Funds'
conclusions. The Funds do not believe that a multiple-class structure having all
of the features of the multiple-class structure of each of the Funds has been
considered by the IRS in other rulings. If dividends declared and paid by a Fund
on any class of shares were to be treated as "preferential," dividends paid by
the Fund to shareholders on all classes of shares during the taxable year would
become non-deductible. In this event, the Fund would not be treated as a
regulated investment company and the Fund would be taxed on its net income,
without any deductions for dividends paid to its shareholders. The resulting
federal and state income tax liability, and any related interest and penalties,
would be payable from and to the extent of such Fund's then available assets and
ultimately would be borne by all current shareholders. The treatment of
dividends declared and paid during the taxable year on any class of shares as
preferential, and the resulting failure of a Fund to be treated as a regulated
investment company, could have additional personal income tax consequences for
shareholders of the Fund, including the taxation of distributions as ordinary
income that otherwise would have been classified as net capital gains.

                  Amounts, other than tax-exempt interest, not distributed on a
timely basis in accordance with a calendar year distribution requirement are
subject to a nondeductible 4% excise tax. To prevent imposition of the excise
tax, each Fund must distribute for each calendar year an amount equal to the sum
of (1) at least 98% of its ordinary income (excluding any capital gains or
losses) for the calendar year, (2) at least 98% of the excess of its capital
gains over capital losses (adjusted for certain ordinary losses) for the
one-year period ending October 31 of such year, and (3) all ordinary income and
capital gain net income (adjusted for certain ordinary losses) for previous
years that were not distributed during such years. A distribution, including an
"exempt-interest dividend," will be treated as paid on December 31, of a
calendar year if it is declared by a Fund during October, November or December
of that year to shareholders of record on a date in such a month and paid by the
Fund during January of the following year. Such distributions will be taxable to
shareholders in the calendar year


                                                                              57
<PAGE>   335
in which the distributions are declared, rather than the calendar year in which
the distributions are received.

                  Distributions of investment company taxable income generally
are taxable to shareholders as ordinary income. Distributions from certain of
the Funds may be eligible for the dividends-received deduction available to
corporations. To the extent dividends received by a Fund are attributable to
foreign corporations, a corporation that owns shares will not be entitled to the
dividends-received deduction with respect to its pro rata portion of such
dividends, since the dividends-received deduction is generally available only
with respect to dividends paid by domestic corporations.

                  Distributions of net long-term capital gains, if any,
designated by the Funds as long-term capital gain dividends are taxable to
shareholders as long-term capital gain, regardless of the length of time the
Funds' shares have been held by a shareholder. All distributions are taxable to
the shareholder in the same manner whether reinvested in additional shares or
received in cash. Shareholders will be notified annually as to the Federal tax
status of distributions.

                  A Fund's net realized capital gains from securities
transactions will be distributed only after reducing such gains by the amount of
any available capital loss carryforwards. Capital losses may be carried forward
to offset any capital gains for eight years, after which any unutilized capital
loss remaining is lost as a deduction. For the fiscal; year ending, the ING Tax
Efficient Equity Fund had capital loss carryforwards equal to $7,352, the ING
Small Cap Growth Fund had capital loss carryforwards equal to $1,539,689, the
ING Mid Cap Growth Fund had capital loss carryforwards equal to $2,076,959, the
ING Large Cap Growth Fund had capital loss carryforwards equal to $1,396,880,
the ING Intermediate Bond Fund had capital loss carryforwards equal to
$1,083,329 and the ING International Bond Fund had capital loss carryforwards
equal to $247,357.

                  Distributions by a Fund reduce the net asset value of the
Fund's shares. Should a distribution reduce the net asset value below a
shareholder's cost basis, such distribution, nevertheless, would be taxable to
the shareholder as ordinary income or capital gain as described above, even
though, from an investment standpoint, it may constitute a partial return of
capital. In particular, investors should be careful to consider the tax
implications of buying shares just prior to a distribution by the Funds. The
price of shares purchased at that time includes the amount of the forthcoming
distribution. Those purchasing just prior to a distribution will receive a
distribution which nevertheless generally will be taxable to them.

                  Upon the taxable disposition (including a sale or redemption)
of shares of a Fund, a shareholder may realize a gain or loss depending upon his
basis in his shares. Such gain or loss generally will be treated as capital gain
or loss if the shares are capital assets in the shareholders' hands. Such gain
or loss will be long-term or short-term, generally depending upon the
shareholder's holding period for the shares. However, a loss realized by a
shareholder on the disposition of Fund shares with respect to which capital gain
dividends have been paid will, to the extent of such capital gain dividends, be
treated as long-term capital loss if such shares have been held by the
shareholder for six months or less. A loss realized on the redemption, sale or
exchange of Fund shares will be disallowed to the extent an exempt interest
dividend was received with respect to those shares if the shares have been held


                                                                              58
<PAGE>   336
by the shareholder for six months or less. Further, a loss realized on a
disposition will be disallowed to the extent the shares disposed of are replaced
(whether by reinvestment of distributions or otherwise) within a period of 61
days beginning 30 days before and ending 30 days after the shares are disposed
of. In such a case, the basis of the shares acquired will be adjusted to reflect
the disallowed loss. Shareholders receiving distributions in the form of
additional shares will have a cost basis for Federal income tax purposes in each
share received equal to the net asset value of a share of the Funds on the
reinvestment date.

                  Some Funds may invest in stocks of foreign companies that are
classified under the Code as passive foreign investment companies ("PFICs"). In
general, a foreign company is classified as a PFIC under the Code if at least
one-half of its assets constitutes investment-type assets or 75% or more of its
gross income is investment-type income. Under the PFIC rules, an "excess
distribution" received with respect to PFIC stock is treated as having been
realized ratably over the period during which the Fund held the PFIC stock. A
Fund itself will be subject to tax on the portion, if any, of the excess
distribution that is allocated to the Fund's holding period in prior taxable
years (and an interest factor will be added to the tax, as if the tax had
actually been payable in such prior taxable years) even though the Fund
distributes the corresponding income to shareholders. Excess distributions
include any gain from the sale of PFIC stock as well as certain distributions
from a PFIC. All excess distributions are taxable as ordinary income.

                  A Fund may be able to elect alternative tax treatment with
respect to PFIC stock. Under an election that currently may be available, a Fund
generally would be required to include in its gross income its share of the
earnings of a PFIC on a current basis, regardless of whether any distributions
are received from the PFIC. If this election is made, the special rules,
discussed above, relating to the taxation of excess distributions, would not
apply. In addition, other elections may become available that would affect the
tax treatment of PFIC stock held by a Fund. Each Fund's intention to qualify
annually as a regulated investment company may limit its elections with respect
to PFIC stock.

                  Because the application of the PFIC rules may affect, among
other things, the character of gains, the amount of gain or loss and the timing
of the recognition of income with respect to PFIC stock, as well as subject a
Fund itself to tax on certain income from PFIC stock, the amount that must be
distributed to shareholders and that will be taxed to shareholders as ordinary
income or long-term capital gain may be increased or decreased substantially as
compared to a Fund that did not invest in PFIC stock. Investors should consult
their own tax advisors in this regard.

                  The taxation of equity options is governed by Code section
1234. Pursuant to Code section 1234, the premium received by a Fund for selling
a put or call option is not included in income at the time of receipt. If the
option expires, the premium is short-term capital gain to the Fund. If the Fund
enters into a closing transaction, the difference between the amount paid to
close out its position and the premium received is short-term capital gain or
loss. If a call option written by a Fund is exercised, thereby requiring the
Fund to sell the underlying security, the premium will increase the amount
realized upon the sale of such security and any resulting gain or loss will be a
capital gain or loss, and will be long-term or short-term depending upon the
holding period of the security. With respect to a put or call option that is
purchased by a Fund, if the option is sold any resulting gain or loss will be a


                                                                              59
<PAGE>   337
capital gain or loss, and will be long-term or short-term, depending upon the
holding period of the option. If the option expires, the resulting loss is a
capital loss and is long-term or short-term, depending upon the holding period
of the option. If the option is exercised, the cost of the option, in the case
of a call option, is added to the basis of the purchased security and in the
case of a put option, reduces the amount realized on the underlying security in
determining gain or loss.

                  Certain of the options, futures contracts, and forward foreign
currency exchange contracts that several of the Funds may invest in are
so-called "section 1256 contracts." With certain exceptions, gains or losses on
section 1256 contracts generally are considered 60% long-term and 40% short-term
capital gains or losses ("60/40"). Also, section 1256 contracts held by a Fund
at the end of a taxable year (and, generally, for purposes of the 4% excise tax,
on October 31 of each year) are "marked-to market" with the result that
unrealized gains or losses are treated as though they were realized and the
resulting gain or loss is treated as 60/40 gain or loss. Investors should
consult their own tax advisors in this regard.

                  Generally, the hedging transactions undertaken by a Fund may
result in "straddles" for federal income tax purposes. The straddle rules may
affect the character of gains (or losses) realized by a Fund. In addition,
losses realized by a Fund on a position that is part of a straddle may be
deferred under the straddle rules, rather than being taken into account in
calculating the taxable income for the taxable year in which such losses are
realized. Because only a few regulations implementing the straddle rules have
been promulgated, the tax consequences to a Fund of hedging transactions are not
entirely clear. Hedging transactions may increase the amount of short-term
capital gain realized by a Fund which is taxed as ordinary income when
distributed to stockholders.

                  A Fund may make one or more of the elections available under
the Code which are applicable to straddles. If a Fund makes any of the
elections, the amount, character and timing of the recognition of gains or
losses from the affected straddle positions will be determined under the rules
according to the election(s) made. The rules applicable under certain of the
elections may operate to accelerate the recognition of gains or losses from the
affected straddle positions.

                  Because application of the straddle rules may affect the
character of gains or losses, defer losses and/or accelerate the recognition of
gains or losses from the affected straddle positions, the amount which must be
distributed to shareholders and which will be taxed to shareholders as ordinary
income or long-term capital gain may be increased or decreased substantially as
compared to a Fund that did not engage in such hedging transactions. Investors
should consult their own tax advisors in this regard.

                  Under the Code, gains or losses attributable to fluctuations
in exchange rates which occur between the time a Fund accrues interest,
dividends or other receivables, or accrues expenses or other liabilities
denominated in a foreign currency, and the time the Fund actually collects such
receivables, or pays such liabilities, generally are treated as ordinary income
or ordinary loss. Similarly, on disposition of debt securities denominated in a
foreign currency and on disposition of certain options and forward and futures
contracts, gains or losses attributable to fluctuations in the value of foreign
currency between the date of


                                                                              60
<PAGE>   338
acquisition of the security or contract and the date of disposition also are
treated as ordinary gain or loss. These gains or losses, referred to under the
Code as "section 988" gains or losses, may increase, decrease, or eliminate the
amount of a Fund's investment company taxable income to be distributed to its
shareholders as ordinary income. Investors should consult their own tax advisors
in this regard.

                  Income received by a Fund from sources within foreign
countries may be subject to withholding and other similar income taxes imposed
by the foreign country. If more than 50% of the value of a Fund's total assets
at the close of its taxable year consists of securities of foreign corporations,
the Fund will be eligible and intends to elect to "pass-through" to its
shareholders the amount of such foreign taxes paid by the Fund. Pursuant to this
election, a shareholder would be required to include in gross income (in
addition to taxable dividends actually received) his pro rata share of the
foreign taxes paid by a Fund and would be entitled either to deduct his pro rata
share of foreign taxes in computing his taxable income or to use it as a foreign
tax credit against his U.S. federal income tax liability, subject to
limitations. No deduction for foreign taxes may be claimed by a shareholder who
does not itemize deductions, but such a shareholder may be eligible to claim the
foreign tax credit (see below). Each shareholder will be notified within 60 days
after the close of a Fund's taxable year whether the foreign taxes paid by a
Fund will "pass-through" for that year and, if so, such notification will
designate (a) the shareholder's portion of the foreign taxes paid to each such
country, and (b) the portion of the dividend which represents income derived
from foreign sources.

                  Generally, a credit for foreign taxes is subject to the
limitation that it may not exceed the shareholder's U.S. tax attributable to his
total foreign source taxable income. For this purpose, if a Fund makes the
election described in the preceding paragraph, the source of the Fund's income
flows through to its shareholders. With respect to a Fund, gains from the sale
of securities will be treated as derived from U.S. sources and certain currency
fluctuations gains, including fluctuation gains from foreign
currency-denominated debt securities, receivables and payables, will be treated
as ordinary income derived from U.S. sources. The limitation on the foreign tax
credit is applied separately to foreign source passive income (as defined for
purposes of the foreign tax credit) including foreign source passive income of a
Fund. The foreign tax credit may offset only 90% of the alternative minimum tax
imposed on corporations and individuals, and foreign taxes generally may not be
deducted in computing alternative minimum taxable income.

                  The Funds are required to report to the Internal Revenue
Service ("IRS") all distributions except in the case of certain exempt
shareholders. All such distributions generally are subject to withholding of
federal income tax at a rate of 31% ("backup withholding") in the case of
non-exempt shareholders if (1) the shareholder fails to furnish the Funds with
and to certify the shareholder's correct taxpayer identification number or
social security number, (2) the IRS notifies the Funds or a shareholder that the
shareholder has failed to report properly certain interest and dividend income
to the IRS and to respond to notices to that effect, or (3) when required to do
so, the shareholder fails to certify that he is not subject to backup
withholding. If the withholding provisions are applicable, any such
distributions, whether reinvested in additional shares or taken in cash, will be
reduced by the amounts required to be withheld. Backup withholding is not an
additional tax. Any amount withheld


                                                                              61
<PAGE>   339
may be credited against the shareholder's U.S. Federal income tax liability.
Investors may wish to consult their tax advisers about the applicability of the
backup withholding provisions.

                  The foregoing discussion relates only to federal income tax
law as applicable to U.S. persons (i.e., U.S. citizens and residents and U.S.
corporations, partnerships, trusts and estates). Distributions by the Funds also
may be subject to state and local taxes and their treatment under state and
local income tax laws may differ from Federal income tax treatment.
Distributions of a Fund which are derived from interest on obligations of the
U.S. Government and certain of its agencies and instrumentalities may be exempt
from state and local income taxes in certain states. Shareholders should consult
their tax advisers with respect to particular questions of federal, state and
local taxation. Shareholders who are not U.S. persons should consult their tax
advisers regarding U.S. and foreign tax consequences of ownership of shares of
the Funds including the likelihood that distributions to them would be subject
to withholding of U.S. tax at a rate of 30% (or at a lower rate under a tax
treaty).

                  ING National Tax-Exempt Bond Fund and ING National Tax-Exempt
Money Market Fund. These Funds intend to manage their respective portfolios so
that each will be eligible to pay "exempt-interest dividends" to shareholders.
The Funds will so qualify if, at the close of each quarter of its taxable year,
at least 50% of the value of their respective total assets consists of state,
municipal, and certain other securities, the interest on which is exempt from
the regular Federal income tax. To the extent that a Fund's dividends
distributed to shareholders are derived from such interest income and are
designated as exempt-interest dividends by the Fund, they will be excludable
from a shareholder's gross income for Federal income tax purposes.
Exempt-interest dividends, however, must be taken into account by shareholders
in determining whether their total incomes are large enough to result in
taxation of up to 85% of their Social Security benefits and certain railroad
retirement benefits. The Funds will inform shareholders annually as to the
portion of the distributions from the Fund which constitute except-interest
dividends. In addition, for corporate shareholders of the Funds, exempt interest
dividends may comprise part or all of an adjustment to alternative minimum
taxable income. Exempt-interest dividends that are attributable to certain
private activity bonds, while not subject to the regular Federal income tax, may
constitute an item of tax preference for purposes of the alternative minimum
tax.

                  To the extent that a Fund's dividends are derived from its
investment company taxable income (which includes interest on its temporary
taxable investments and the excess of net short-term capital gain over net
long-term capital loss), they are considered ordinary (taxable) income for
Federal income tax purposes. Such dividends will not qualify for the
dividends-received deduction for corporations. Distributions, if any, of net
long-term capital gains (the excess of net long-term capital gain over net
short-term capital loss) designated by a Fund as long-term capital gain
dividends are taxable to shareholders as long-term capital gain regardless of
the length of time the shareholder has owned shares of the Fund.

Capitalization

                  The Trust is a Delaware business trust established under a
Trust Instrument dated July 30, 1998 and currently consists of twenty-seven
separately managed portfolios, all of which are discussed in this SAI. Each
portfolio is comprised of five different classes of shares -- Class A shares,
Class B shares, Class C shares, Class X shares and Class I shares, except that
the ING National Tax-Exempt Bond Fund and the ING National Tax-Exempt Money
Market Fund do not offer Class X and Class I shares, and the ING Stable Value
Fund only offers Class A and Class B shares.

                  The capitalization of the Funds consists solely of an
unlimited number of shares of beneficial interest with a par value of $0.001
each. The Board of Trustees may establish additional Funds (with different
investment objectives and fundamental policies) at any time in the future.
Establishment and offering of additional Funds will not alter the rights of the
shareholders. When issued, shares are fully paid, non-assessable, redeemable and
freely transferable. Shares do not have preemptive rights, conversion rights or
subscription rights. In any liquidation of a Fund, each shareholder is entitled
to receive his pro rata share of the net assets of that Fund.

                  In the event of a liquidation or dissolution of the Funds or
an individual Fund, shareholders of a particular Fund would be entitled to
receive the assets available for distribution belonging to such Fund, and a
proportionate distribution, based upon the relative net asset values of the
respective Funds, of any general assets not belonging to any particular Fund
which are available for distribution. Shareholders of a Fund are entitled to
participate in the net distributable assets of the particular Fund involved in
liquidation, based on the number of shares of the Fund that are held by each
shareholder.

Voting Rights

                  Under the Trust Instrument, the Funds are not required to hold
annual meetings of each Fund's shareholders to elect Trustees or for other
purposes. It is not anticipated that the Funds will hold shareholders' meetings
unless required by law or the Trust Instrument. In this regard, the Trust will
be required to hold a meeting to elect Trustees to fill any existing vacancies
on the Board if, at any time, fewer than a majority of the Trustees have been
elected by the shareholders of the Funds. In addition, the Trust Instrument
provides that the holders of not less than two-thirds of the outstanding shares
of the Funds may remove persons serving as Trustee either by declaration in
writing or at a meeting called for such purpose. The Trustees are required to
call a meeting for the purpose of considering the removal of persons serving as
Trustee if requested in writing to do so by the holders of not less than 10% of
the outstanding shares of the Funds. To the extent required by applicable law,
the Trustees shall assist shareholders who seek to remove any person serving as
Trustee.

                  The Funds' shares do not have cumulative voting rights, so
that the holder of more than 50% of the outstanding shares may elect the entire
Board of Trustees, in which case the holders of the remaining shares would not
be able to elect any Trustees.


                                                                              63
<PAGE>   341
                  Shareholders of all of the Funds, as well as those of any
other investment portfolio now or hereafter offered by the Fund, will vote
together in the aggregate and not separately on a Fund-by-Fund basis, except as
otherwise required by law or when permitted by the Board of Trustees. Rule 18f-2
under the 1940 Act provides that any matter required to be submitted to the
holders of the outstanding voting securities of an investment company such as
the Funds shall not be deemed to have been effectively acted upon unless
approved by the holders of a majority of the outstanding shares of each Fund
affected by the matter. A Fund is affected by a matter unless it is clear that
the interests of each Fund in the matter are substantially identical or that the
matter does not affect any interest of the Fund. Under the Rule, the approval of
an investment advisory agreement or any change in a fundamental investment
policy would be effectively acted upon with respect to a Fund only if approved
by a majority of the outstanding shares of such Fund. However, the Rule also
provides that the ratification of the appointment of independent auditors, the
approval of principal underwriting contracts and the election of trustees may be
effectively acted upon by shareholders of the Funds voting together in the
aggregate without regard to a particular Fund.

Performance Information

                  The Funds may, from time to time, include their yields and
average annual total returns in advertisements or reports to shareholders or
prospective investors.

                  Quotations of average annual total return will be expressed in
terms of the average annual compounded rate of return of a hypothetical
investment in a Fund over periods of 1, 5 and 10 years (up to the life of the
Fund), calculated pursuant to the following formula:

                        n
                  P(l+T) = ERV

                  (where P = a hypothetical initial payment of $1,000, T = the
average annual total return, n = the number of years, and ERV = the ending
redeemable value of a hypothetical $1,000 payment made at the beginning of the
period). All total return figures will reflect a proportional share of Fund
expenses (net of certain reimbursed expenses) on an annual basis, and will
assume that all dividends and distributions are reinvested when paid.

                  Current yields for each of the ING Money Market Funds will be
based on the change in the value of a hypothetical investment (exclusive of
capital changes such as gains or losses from the sale of securities and
unrealized appreciation and depreciation) over a particular seven-day period,
less a pro rata share of each Fund's expenses accrued over that period (the
"base period"), and stated as a percentage of the investment at the start of the
base period (the "base period return"). The base period return is then
annualized by multiplying by 365/7, with the resulting yield figure carried to
at least the nearest hundredth of one percent. "Effective yield" for each Money
Market Fund assumes that all dividends received during the base period have been
reinvested. Calculation of "effective yield" begins with the same "base period
return" used in the calculation of yield, which is then annualized to reflect
weekly compounding pursuant to the following formula:

Effective Yield = [(Base Period Return +1) [(RAISED TO THE (365/7) POWER]] - 1.


                                                                              64

                  Quotations of yield for the Funds which are not money market
funds will be based on the investment income per share earned during a
particular 30-day period, less expenses accrued during a period ("net investment
income") and will be computed by dividing net investment income by the maximum
offering price per share on the last day of the period, according to the
following formula:

                              a - b     6
                  YIELD = 2[( ----- +1 )  - 1]
                               cd

                  where a = dividends and interest earned during the period, b =
expenses accrued for the period (net of any reimbursements), c = the average
daily number of shares outstanding during the period that were entitled to
receive dividends, and d = the maximum offering price per share on the last day
of the period.

                  Quotations of the tax-equivalent yield for the ING National
Tax-Exempt Money Market Fund and the ING National Tax-Exempt Bond Fund will be
calculated according to the following formula:

                                             E
                  TAX EQUIVALENT YIELD = ----------

                  E = Tax-Exempt yield
                  p = stated income tax rate

                  Quotations of yield and total return will reflect only the
performance of a hypothetical investment in the Funds during the particular time
period shown. Yield and total return for the Funds will vary based on changes in
the market conditions and the level of a Fund's expenses, and no reported
performance figure should be considered an indication of performance which may
be expected in the future.

                  The Funds may also calculate performance using any other
historical measure of performance (not subject to any prescribed method of
computation) if the measurement reflects all elements of return. If used, such
performance measurements will disclose the length of and the last day in the
base period used in calculating the quotation, a description of the method by
which the performance data is calculated, and the income tax rate used in the
calculation, if applicable.

                  In connection with communicating its yields or total return to
current or prospective shareholders, the Funds also may compare these figures to
the performance of other mutual funds tracked by mutual fund rating services or
to other unmanaged indices which may assume reinvestment of dividends but
generally do not reflect deductions for administrative and management costs.

                  The Funds may from time to time include in advertisements,
sales literature, communications to shareholders and other materials,
comparisons of its total return to the return of other mutual funds with similar
investment objectives, broadly-based market indices, other investment

                                    APPENDIX


DESCRIPTION OF MOODY'S BOND RATINGS:

         Excerpts from Moody's description of its four highest bond ratings are
listed as follows: Aaa -- judged to be the best quality and they carry the
smallest degree of investment risk; Aa -- judged to be of high quality by all
standards. Together with the Aaa group, they comprise what are generally know as
high grade bonds; A -- possess many favorable investment attributes and are to
be considered as "upper medium grade obligations"; Baa -- considered to be
medium grade obligations, i.e., they are neither highly protected nor poorly
secured. Interest payments and principal security appear adequate for the
present but certain protective elements may be lacking or may be
characteristically unreliable over any great length of time. This group is the
lowest which qualifies for investment grade. Other Moody's bond descriptions
include: Ba -- judged to have speculative elements, their future cannot be
considered as well assured; B -- generally lack characteristics of the desirable
investment; Caa -- are of poor standing. Such issues may be in default or there
may be present elements of danger with respect to principal or interest; Ca --
speculative in a high degree, often in default; C -- lowest rated class of
bonds, regarded as having extremely poor prospects.

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


DESCRIPTION OF S&P'S BOND RATINGS:

         Excerpts from S&P's description of its four highest bond ratings are
listed as follows: AAA -- highest grade obligations, in which capacity to pay
interest and repay principal is extremely strong; AA -- also qualify as high
grade obligations, having a very strong capacity to pay interest and repay
principal, and differs from AAA issues only in a small degree; A -- regarded as
upper medium grade, having a strong capacity to pay interest and repay
principal, although they are somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than debt in higher rated
categories; BBB -- regarded as having an adequate capacity to pay interest and
repay principal. Whereas it normally exhibits adequate protection parameters,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity to pay interest and repay principal for debt in this
category than in higher rated categories. This group is the lowest which
qualifies for investment grade. BB, B, CCC, CC -- predominantly speculative with
respect to capacity to pay interest and repay principal in accordance with terms
of the obligations; BB indicates the highest grade and CC the lowest within the
speculative rating categories.

         S&P applies indicators "+," no character, and "-" to its rating
categories. The indicators show relative standing within the major rating
categories.

                                                                              82
<PAGE>   360
DESCRIPTION OF MOODY'S RATINGS OF NOTES AND VARIABLE RATE DEMAND INSTRUMENTS:

         Moody's ratings for state and municipal short-term obligations will be
designated Moody's Investment Grade or MIG. Such ratings recognize the
differences between short-term credit and long-term risk. Short-term ratings on
issues with demand features (variable rate demand obligations) are
differentiated by the use of the VMIG symbol to reflect such characteristics as
payment upon periodic demand rather than fixed maturity dates and payments
relying on external liquidity.

         MIG 1/VMIG 1: This designation denotes best quality. There is present
strong protection by established cash flows, superior liquidity support or
demonstrated broad-based access to the market for refinancing.

         MIG 2/VMG 2: This denotes high quality. Margins of protection are ample
although not as large as in the preceding group.

DESCRIPTION OF MOODY'S TAX-EXEMPT COMMERCIAL PAPER RATINGS:

         Moody's commercial paper ratings are opinions of the ability of issuers
to repay punctually promissory obligations which have an original maturity not
exceeding nine months. Moody's makes no representation that such obligations are
exempt from registration under the Securities Act of 1933, nor does it represent
that any specific note is a valid obligation of a rated issuer or issued in
conformity with any applicable law. The following designations, all judged to be
investment grade, indicate the relative repayment ability of rated issuers of
securities in which the Trust may invest.

         PRIME-1: Issuers rated Prime-1 (or supporting institutions) have a
superior ability for repayment of senior short-term promissory obligations.

         PRIME-2: Issuers rated Prime-2 (or supporting institutions) have a
strong ability for repayment of senior short-term promissory obligations.

DESCRIPTION OF S&P'S RATINGS FOR MUNICIPAL BONDS:

INVESTMENT GRADE

         AAA: Debt rated "AAA" has the highest rating assigned by S&P. Capacity
to pay interest and repay principal is extremely strong.

         AA: Debt rated "AA" has a very strong capacity to pay interest and
repay principal and differs from the highest rated issues only in a small
degree.

         A: Debt rated "A" has strong capacity to pay interest and repay
principal although it is somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than debt in higher rated
categories.

                                                                              83
<PAGE>   361
         BBB: Debt rated "BBB" is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher rated categories.

SPECULATIVE GRADE

         BB, B, CCC, CC: Debt rated in these categories is regarded as having
predominantly speculative characteristics with respect to capacity to pay
interest and repay principal. While such debt will likely have some quality and
protective characteristics, these are outweighed by large uncertainties or major
risk exposures to adverse conditions.

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

         D: Debt rated "D" is in default, and payment of interest and/or
repayment of principal is in arrears.

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

DESCRIPTION OF S&P'S RATINGS FOR INVESTMENT GRADE MUNICIPAL NOTES AND SHORT-TERM
DEMAND OBLIGATIONS:

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

         SP-2: Issues carrying this designation have a satisfactory capacity to
pay principal and interest.

DESCRIPTION OF S&P'S RATINGS FOR DEMAND OBLIGATIONS AND TAX-EXEMPT COMMERCIAL
PAPER:

         An S&P commercial paper rating is a current assessment of the
likelihood of timely repayment of debt having an original maturity of no more
than 365 days. The two rating categories for securities in which the Trust may
invest are as follows:

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

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

                                                                              84

(4)     Filed herewith.
(5)     To be filed by amendment.


Item 24.     Persons Controlled by or under Common Control with the Fund.

        None.


Item 25.     Indemnification.

    Reference is made to Article IX of Registrants By-Laws and paragraphs 1.11
    of the Distribution Agreement.

    Insofar as indemnification for liabilities arising under the Securities Act
    of 1933 (the "Securities Act") may be permitted to trustees, officers and
    controlling persons of the Registrant pursuant to the foregoing provisions,
    or otherwise, the Registrant understands that in the opinion of the
    Securities and Exchange Commission such indemnification is against public
    policy as expressed in the Securities Act and is, therefore, unenforceable.
    In the event that a claim for indemnification against such liabilities
    (other than the payment by the Registrant of expenses incurred or paid by a
    trustee, officer or controlling person of the Registrant in the successful
    defense of any action, suit or proceeding) is asserted by such trustee,
    officer or controlling person in connection with the securities being
    registered, the Registrant will, unless in the opinion of its counsel the
    matter has been settled by controlling precedent, submit to a court of
    appropriate jurisdiction the question whether such indemnification by it is
    against public policy as expressed in the Securities Act and will be
    governed by the final adjudication of such issue.
<PAGE>   364
    The Registrant is covered under an insurance policy insuring its officers
    and trustees against liabilities, and certain costs of defending claims
    against such officers and trustees, to the extent such officers and trustees
    are not found to have committed conduct constituting willful misfeasance,
    bad faith, gross negligence or reckless disregard in the performance of
    their duties. The insurance policy also insures the Registrant against the
    cost of indemnification payments to officers under certain circumstances.

    Section 12 of the Management Agreement between Registrant and Manager,
    Section 8 of the Sub-Advisory Agreements and Section 1.11 of the
    Distribution Agreement between the Registrant and Distributor limit the
    liability of Manager, the Sub-Advisors and the Distributor to liabilities
    arising from willful misfeasance, bad faith or gross negligence in the
    performance of their respective duties or from reckless disregard by them of
    their respective obligations and duties under the agreements.

    The Registrant hereby undertakes that it will apply the indemnification
    provisions of its Trust Instrument, By-Laws, Management Agreement and
    Distribution Agreement in a manner consistent with Release No. 11330 of the
    Securities and Exchange Commission under the 1940 Act so long as the
    interpretations of Section 17(h) and 17(i) of such Act remain in effect and
    are consistently applied.

                                            File Nos. 333-59745/811-08895

Dear Sirs:

                  As counsel to the ING Funds Trust (the "Trust"), we have
reviewed Post-Effective Amendment No. 4 to the Trust's Registration Statement on
Form N-1A (the "Amendment"). The Amendment is being filed pursuant to Rule 485
of the Securities Act of 1933, as amended, and it is proposed that it will
become effective immediately upon filing pursuant to paragraph (b).

                  Based upon our review, we advise you that the Amendment does
not include disclosure which we believe would render it ineligible to become
effective under paragraph (b) of Rule 485.

                  It is our opinion that the securities being registered will
when sold, be legally issued, fully paid and non-assessable. We hereby consent
to the filing of this opinion as an exhibit to Post-Effective Amendment No. 4
and consent to the reference to our firm as Counsel in Post-Effective Amendment
No. 4 to Registration No. 333-59745.


                            Very truly yours,



                            /s/Paul, Weiss, Rifkind, Wharton & Garrison
