[PHOTO OF JAMES M. HENNESSY]
JAMES M. HENNESSY

Dear Shareholder,

The past year has been unpredictable for investors. Strong growth in the overall
economy coupled with questions concerning mutual fund trading practices have
challenged investors.

In general, economic activity has continued to increase, with the growth being
widespread. Personal consumption of goods and services is leading the recovery
supported by corporate purchases of equipment and software and by Government
spending on defense. Worries of possible interest rate increases, worsening
global turmoil and increasing oil prices have reduced the gains the market
realized in the first few months of 2004.

However, investors remain steadfast as nearly each of the last six months has
seen an overall increase in assets invested in mutual funds despite continuing
investigations into late trading and market timing issues at some of the largest
and most respected financial services companies in the country.

You should have received a letter from Thomas J. McInerney, the Chief Executive
Officer of ING U.S. Financial Services, which provided information about the
internal review ING management conducted regarding trading practices in ING
mutual fund products. If you did not receive a copy of the letter, please
contact Investor Services at 1-800-992-0180 and we will provide you with a copy.

I wish to thank you on behalf of everyone here at ING Funds for your continued
confidence. We look forward to helping you meet your investment goals in the
future.

Sincerely,


/s/ James M. Hennessy


James M. Hennessy

MARKET PERSPECTIVE: SIX MONTHS ENDED JUNE 30, 2004

OVERVIEW

Perhaps it was inevitable that the markets should be a little neurotic after the
heady gains of 2003. But whatever the reasons, investors in 2004 alternately
cheered and fretted over the developing economic outlook, sending markets up,
down and up again before ending the first six months of 2004 with modest and
distinctly fragile gains.

At first the worry was the so-called jobless recovery, then half way through the
six-month period a very strong U.S. employment report was released. The report
generated euphoria until people realized that as the job market tightens,
inflation picks up and rising interest rates were likely not far away. Investors
took comfort from Federal Open Market Committee ("FOMC") Chairman Greenspan's
soothing advice that the rebound in interest rates would be "measured". But as
the six months ended June 30, 2004 drew to a close, attention switched nervously
to the impending U.S. earnings season and the strong possibility that the
splendid results of the last few quarters would likely not be maintained.

GLOBAL EQUITIES managed a 3.52% return, net of withholding tax on dividends, for
the six months ended June 30, 2004 according to the Morgan Stanley Capital
International ("MSCI") World Index(1) in dollars, after peaking on average in
mid February and spending much of May in negative territory.

Among CURRENCIES, the euro reached a post launch record also in mid February
before retreating and ending about 3.0% lower for the six months ended June 30,
2004. The British pound ended the six months 2.0% higher against the dollar, as
the Bank of England became the first of the major central banks to raise
interest rates. The yen lost approximately 1.5%, ironically after the Bank of
Japan stopped buying dollars to keep the yen weak, spending a staggering $144
billion in the first quarter of 2004 to do so.

FIXED INCOME MARKET

U.S. FIXED INCOME classes started 2004 as they had ended 2003. Disappointing
jobs reports, together with stubbornly high new unemployment claims, suggested
continuing weakness, and gave bond investors a solid first quarter of gains.
That all changed on the first Friday in April 2004, with the very bullish U.S.
employment report. Investment grade bonds unsurprisingly bore the brunt of fears
that a new cycle of rising interest rates from multi-decade low levels was about
to start. For the six months ended June 30, 2004, the Lehman Brothers Aggregate
Bond Index(2) of investment grade bonds returned a tiny 0.16%. The Lehman
Brothers Corporate Index(3) component and the Lehman Brothers Treasury Bond
Index(4) fell by 0.26% and 0.20%, respectively. Ten-year Treasury yields rose by
36 basis points to 4.62%, passing through rates not seen in nearly two years.
Yields on 90-day Treasury Bills rose 39 basis points to 1.3%, emphatically
breaching the 1.0% level, a rate above which they had not closed since June 9,
2003. High yield bonds did better, the Lehman Brothers U.S. Corporate High Yield
Bond Index(5) hung on to return 1.35% for the six-month period.

DOMESTIC EQUITY MARKET

The U.S. EQUITIES market rose 3.44% in the six months ended June 30, 2004, based
on the Standard & Poor's ("S&P") 500 Index(6) including dividends. This implies
a price-to-earnings (P/E) level of just over 17 times 2004 earnings. Three
strong employment reports in the second quarter of 2004 were welcomed, but all
was not in harmony. For while successive, upbeat economic statistics sang of
good economic times, there was also a steady drumbeat of evidence that inflation
was picking up. The Federal Funds rate at just 1.0% meant that real interest
rates were becoming ever more negative at the same time, while the economy was
growing at over 4.0%. With labor markets tightening and oil prices breaking
above $40 per barrel, this appears to be an increasingly unstable situation.
Meanwhile, the FOMC took almost the entire second quarter of 2004 before
increasing the Federal Funds rate to 1.25% on June 30, 2004. However, in the
week before the increase, the wind seemed to shift again. First quarter of 2004
gross domestic product ("GDP") growth was revised down to 3.9%, durable goods
orders fell, and retailers and auto companies complained of slack sales. On the
day the FOMC raised rates, the Chicago Purchasing Managers' Index(7) had its
largest monthly drop in 30 years. Perhaps Greenspan's "measured" policy was
right, but perhaps something else was wrong. The first half of 2004 ended, with
investors again nervously awaiting the employment report two days later.

MARKET PERSPECTIVE: SIX MONTHS ENDED JUNE 30, 2004

INTERNATIONAL MARKETS

Most INTERNATIONAL MARKETS eked out similarly modest gains for the six months
ended June 30, 2004, but JAPAN was the star, rising 10.73% in dollars according
to the MSCI Japan Index(8). Sentiment was encouraged by first quarter GDP
growth, reported at a surprisingly strong 6.1% annualized, suggesting that the
world's second largest economy was at last emerging from its slump of more than
a decade.

EUROPEAN EX UK MARKETS gained 2.88% in dollars in the six months ended June 30,
2004, according to the MSCI Europe ex UK Index(9). Buoyant exports were about
the only good news, as domestic demand still languished under unemployment of
9.0%. Still, these markets look relatively cheap.

Finally the UK market rose 3.32% in dollars during the first six months of 2004,
based on the MSCI UK Index(10). The economy appears to be strong, but the
troubling imbalances of an over-indebted consumer and a housing price bubble led
to three interest rate increases by the Bank of England, with more likely on the
way.

ING VP NATURAL RESOURCES TRUST                        PORTFOLIO MANAGERS' REPORT

PORTFOLIO MANAGEMENT TEAM: A team of investment professionals led by James A.
Vail, ING Investment Management Co. (formerly, Aeltus Investment Management,
Inc.)-- the Sub-Adviser.

GOAL: The ING VP Natural Resources Trust (the "Trust") seeks long-term growth of
capital through investment primarily in common stocks of companies that own or
develop natural resources and other basic commodities, or supply goods and
services to such companies. Capital appreciation will be the primary determinant
of total return and income is a secondary consideration.

PERFORMANCE: For the six months ended June 30, 2004, the Trust returned -1.38%,
compared to the Standard & Poor's ("S&P") 500 Index(1) and the Goldman Sachs
Natural Resources Index(2), which returned 3.44% and 8.15%, respectively, for
the same period.

PORTFOLIO SPECIFICS: At the beginning of 2004, the Portfolio was underweight in
the energy sector, specifically the larger capitalization integrated oils and
oil service names, which hurt performance. Not owning large-capitalization
chemical companies, Dow Chemical Company and Du Pont de Nemours and Company, and
being underweight Alcoa, Inc. helped performance. The primary reason for the
Trust's underperformance in the second half of the reporting period was likely
being underweight energy, which was a strong performer, and overweight
materials. It appears the materials sector suffered as concerns over a slowdown
in the Chinese economy caused a dramatic reversal in commodity prices. Our prior
holdings in United States Steel Corporation, Freeport-McMoRan Copper and Gold,
Inc., and Barrick Gold Corporation were hurt by this severe downturn in metal
prices. Stock selection was the primary reason for trailing the benchmark in
energy.

MARKET OUTLOOK: Natural resources and materials have experienced significant
volatility recently. This volatility, in our opinion, has been driven by
familiar fears of a hard landing in China's economy, interest rate increases in
the United States, and Middle East uncertainties. Nevertheless, the
macroeconomic environment appears to be positive for natural resources. Crude
oil futures have fallen, which should bode well for continued global economic
expansion. Natural gas, primarily reflecting domestic demand, remains at
relatively high levels and given limited new production should stay so. Other
significant materials, such as copper, nickel, aluminum, and zinc, may have
retreated as speculators have exited the sector but should edge higher as global
demand enters a more sustainable phase.

Despite the recent volatility, investment in natural resources lagged other
sectors in the late 1990s and early into the 21st century. This lack of
investment, in the face of incremental demand from China, India, and Eastern
Europe, may argue for higher material prices in the years ahead. As China shifts
from a rural-based economy to a more urban and industrial center, this, in our
opinion, sets the stage for attractive materials prices and sector corporate
profits into the intermediate term. History points to similar experiences in the
United States from 1900-1945 and Japan from 1945-1970 as templates for how the
Chinese demand for materials and energy should unfold.

Going forward, we believe the Trust is well positioned to benefit from the
unfolding fundamentals as we perceive them. Approximately 58% of the Trust's
holdings are in the broad energy sector to include oil and gas producers, energy
services, drillers and producers of coal and uranium. 36% is represented by
materials and paper and forest products, with the remainder in cash. We continue
to search for companies in all sectors that possess attractive production growth
potential selling at reasonable valuations.

THE VIEWS EXPRESSED IN THIS REPORT REFLECT THOSE OF THE PORTFOLIO MANAGERS, ONLY

VIEWS ARE SUBJECT TO CHANGE AT ANY TIME BASED ON MARKET AND OTHER CONDITIONS.

TRUST HOLDINGS ARE SUBJECT TO CHANGE DAILY.

(1)  The S&P 500 Index is an unmanaged index that measures the performance of
     securities of approximately 500 large-capitalization companies whose
     securities are traded on major U.S. stock markets.

(2)  The Goldman Sachs Natural Resources Index is a
     market-capitalization-weighted index of 112 stocks designed to measure the
     performance of companies in the natural resources sector, which includes
     energy, precious metals, timber, and other sub-sectors.

(3)  The Index commenced in August 1996.

PRINCIPAL RISK FACTOR(s): Price volatility due to non-diversification and
concentration in natural resource companies. Securities of such companies may be
subject to broad price fluctuations, reflecting volatility of energy and basic
materials' prices and possible instability of supply of various natural
resources. The Trust's investments in foreign securities involve special risks
including currency fluctuations, lower liquidity, political and economic
uncertainties, and differences in accounting standards. The investment of a
large percentage of the Trust's assets in the securities of a small number of
issuers may cause the Trust's share price to fluctuate more than that of a
diversified investment company. The Trust should be considered as a vehicle for
diversification and not as a balanced investment program. The value of debt
securities may fall when interest rates rise.

          NOTES TO FINANCIAL STATEMENTS as of June 30, 2004 (Unaudited)

NOTE 1 -- ORGANIZATION

ORGANIZATION. ING VP Natural Resources Trust (the "Trust") is an open-end,
non-diversified management investment company registered under the Investment
Company Act of 1940, as amended. The Trust was organized as a Massachusetts
business trust on November 15, 1988 and commenced operation in 1991.

NOTE 2  SIGNIFICANT ACCOUNTING POLICIES

The following significant accounting policies are consistently followed by the
Trust in the preparation of its financial statements:

A.   SECURITY VALUATION. Investments in equity securities traded on a national
     securities exchange are valued at the last reported sale price. Securities
     reported by NASDAQ will be valued at the NASDAQ official closing prices.
     Securities traded on an exchange or NASDAQ for which there has been no sale
     and equity securities traded in the over-the-counter-market are valued at
     the mean between the last reported bid and ask prices. All investments
     quoted in foreign currencies will be valued daily in U.S. dollars on the
     basis of the foreign currency exchange rates prevailing at that time. Debt
     securities are valued at prices obtained from independent services or from
     one or more dealers making markets in the securities and may be adjusted
     based on the Trust's valuation procedures. U.S. Government obligations are
     valued by using market quotations or independent pricing services which use
     prices provided by market-makers or estimates of market values obtained
     from yield data relating to instruments or securities with similar
     characteristics.

     Securities and assets for which market quotations are not readily available
     (which may include certain restricted securities which are subject to
     limitations as to their sale) are valued at their fair values as determined
     in good faith by or under the supervision of the Trust's Board of Trustees
     ("Board"), in accordance with methods that are specifically authorized by
     the Board. Securities traded on exchanges, including foreign exchanges,
     which close earlier than the time that the Trust calculates its net asset
     value may also be valued at their fair values as determined in good faith
     by or under the supervision of the Trust's Board, in accordance with
     methods that are specifically authorized by the Board. If a significant
     event which is likely to impact the value of one or more foreign securities
     held by the Trust occurs after the time at which the foreign market for
     such security(ies) closes but before the time that the Trust's net asset
     value is calculated on any business day, such event may be taken into
     account in determining the fair value of such security(ies) at the time the
     Trust calculates its net asset value. For these purposes, significant
     events after the close of trading on a foreign market may include, among
     others, securities trading in the U.S. and other markets, corporate
     announcements, natural and other disasters, and political and other events.
     Among other elements of analysis, the Board has authorized the use of one
     or more research services to assist with the determination of the fair
     value of foreign securities in light of significant events. Research
     services use statistical analyses and quantitative models to help determine
     fair value as of the time the Trust calculates its net asset value. Unlike
     the closing price of a security on an exchange, fair value determinations
     employ elements of judgment, and the fair value assigned to a security may
     not represent the actual value that the Trust could obtain if it were to
     sell the security at the time of the close of the NYSE. Investments in
     securities maturing in less than 60 days are valued at amortized cost,
     which, when combined with accrued interest, approximates market value.

B.   SECURITY TRANSACTIONS AND REVENUE RECOGNITION. Securities transactions are
     accounted for on the trade date. Realized gains and losses are reported on
     the basis of identified cost of securities sold. Interest income is
     recorded on an accrual basis except when collection is not expected.
     Dividend income is recorded on the ex-dividend date, or for certain foreign
     securities, when the information becomes available to the Trust. Premium
     amortization and discount accretion are determined by the effective yield
     method.

C.   FEDERAL INCOME TAXES. It is the policy of the Trust to comply with
     subchapter M of the Internal Revenue Code and related excise tax provisons
     applicable to regulated investment companies and to distribute
     substantially all of its net investment income and any net realized capital

                                       10
<Page>

    NOTES TO FINANCIAL STATEMENTS as of June 30, 2004 (Unaudited) (continued)

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     gains to its shareholders. Therefore, no federal income tax provision is
     required. No capital gain distributions shall be made until any capital
     loss carryforwards have been fully utilized or expired.

D.   DISTRIBUTIONS TO SHAREHOLDERS. Dividends from net investment income and net
     realized gains, if any are declared and paid annually by the Trust.
     Distributions are determined annually in accordance with federal tax
     principles which may differ from accounting principles generally accepted
     in the United States of America for investment companies. The Trust may
     make distributions on a more frequent basis to comply with the distribution
     requirements of the Internal Revenue Code. Distributions are recorded on
     the ex-dividend date.

E.   USE OF ESTIMATES. Management of the Trust has made certain estimates and
     assumptions relating to the reporting of assets, liabilities, income, and
     expenses to prepare these financial statements in conformity with
     accounting principles generally accepted in the United States of America.
     Actual results could differ from these estimates.

F.   FOREIGN CURRENCY TRANSLATION. The books and records of the Trust are
     maintained in U.S. dollars. Any foreign currency amounts are translated
     into U.S. dollars on the following basis:

          (1)  Market value of investment securities, other assets and
               liabilities -- at the exchange rates prevailing at the end of the
               day.

          (2)  Purchases and sales of investment securities, income and expenses
               -- at the rates of exchange prevailing on the respective dates of
               such transactions.

     Although the net assets and the market values are presented at the foreign
     exchange rates at the end of the day, the Trust does not isolate the
     portion of the results of operations resulting from changes in foreign
     exchange rates on investments from the fluctuations arising from changes in
     market prices of securities held. Such fluctuations are included with the
     net realized and unrealized gains or losses from investments. For
     securities which are subject to foreign withholding tax upon disposition,
     liabilities are recorded on the Statement of Assets and Liabilities for the
     estimated tax withholding based on the securities current market value.
     Upon disposition, realized gains or losses on such securities are recorded
     net of foreign withholding tax.

     Reported net realized foreign exchange gains or losses arise from sales of
     foreign currencies, currency gains or losses realized between the trade and
     settlement dates on securities transactions, the difference between the
     amounts of dividends, interest, and foreign withholding taxes recorded on
     the Trust's books and the U.S. dollar equivalent of the amounts actually
     received or paid. Net unrealized foreign exchange gains and losses arise
     from changes in the value of assets and liabilities other than investments
     in securities at period end, resulting from changes in the exchange rate.
     Foreign security and currency transactions may involve certain
     considerations and risks not typically associated with investing in U.S.
     companies and U.S. Government securities. These risks include, but are not
     limited to, revaluation of currencies and future adverse political and
     economic developments which could cause securities and their markets to be
     less liquid and prices more volatile than those of comparable U.S.
     companies and U.S. Government securities.

G.   FORWARD FOREIGN CURRENCY CONTRACTS. The Trust may enter into forward
     foreign currency contracts primarily to hedge against foreign currency
     exchange rate risks on their non-U.S. dollar denominated investment
     securities. When entering into a currency forward contract, the Trust
     agrees to receive or deliver a fixed quantity of foreign currency for an
     agreed-upon price on an agreed future date. These contracts are valued
     daily and the Trust's net equity therein, representing unrealized gain or
     loss on the contracts as measured by the difference between the forward
     foreign exchange rates at the dates of entry into the contracts and the
     forward rates at the reporting date, is included on the Statement of Assets
     and Liabilities. Realized and unrealized gains and losses are included on
     the Statement of Operations. These instruments involve market and/or credit
     risk in excess of the amount recognized on the Statement of Assets and
     Liabilities. Risks arise from the possible inability of counterparties to
     meet the terms of their contracts and from movement in currency and
     securities values and interest rates. At June 30, 2004, the Trust did not
     have any open forward foreign currency contracts.

    NOTES TO FINANCIAL STATEMENTS as of June 30, 2004 (Unaudited) (continued)

NOTE 3 -- INVESTMENT MANAGEMENT AND ADMINISTRATIVE FEES

The Trust pays an investment management fee to ING Investments, LLC (the
"Investment Manager"), an indirect wholly-owned subsidiary of ING Groep N.V., at
an annual rate of 1.00% of the Trust's average daily net assets.

The Investment Manager has entered into an Expense Limitation Agreement with the
Trust, under which it will limit expenses of the Trust to the extent of 2.50% of
the value of the Trust's average daily net assets, excluding interest, taxes,
brokerage and extraordinary expenses. Fee waivers and/or reimbursements by the
Investment Manager may vary in order to achieve such contractually obligated
expense limit.

The Expense Limitation Agreement is contractual and shall renew automatically
for one-year terms unless ING Investments provides written notice of the
termination of the Expense Limitation Agreement within 90 days of the end of the
then current term.

The Investment Manager may at a later date recoup from the Trust for management
fees waived and other expenses assumed by the Investment Manager during the
previous 36 months, but only if, after such reimbursement, the Trust's expense
ratio does not exceed the percentage described above. No reimbursement was
required for the six months ended June 30, 2004.

The Investment Manager has entered into a Sub-Advisory Agreement with ING
Investment Management Co., (formerly, Aeltus Investment Management, Inc., "ING
IM"), an indirect wholly-owned subsidiary of ING Groep N.V.

ING Funds Services, LLC (the "Administrator"), an indirect wholly-owned
subsidiary of ING Groep N.V., serves as Administrator to the Trust. The Trust
pays the Administrator a fee calculated at an annual rate of 0.10% of the
Trust's average daily net assets.

NOTE 4 -- OTHER TRANSACTIONS WITH AFFILIATED AND RELATED PARTIES

At June 30, 2004, the Trust had the following amounts recorded in payable to
affiliates on the accompanying Statements of Assets and Liabilities:

<Table>
<Caption>
  ACCRUED
INVESTMENT            ACCRUED
MANAGEMENT        ADMINISTRATIVE

$   19,828          $    1,983         $  21,811
</Table>

The Trust has adopted a Retirement Policy covering all independent trustees of
the Trust who will have served as an independent trustee for at least five years
at the time of retirement. Benefits under this plan are based on an annual rate
as defined in the plan agreement.

NOTE 5 -- INVESTMENT TRANSACTIONS

The cost of purchases and proceeds from sales of investments for the six months
ended June 30, 2004, excluding short-term securities, were $15,655,930 and
$14,816,207, respectively.

NOTE 6 -- OTHER ACCRUED EXPENSES AND LIABILITIES

At June 30, 2004, the Trust had a payable for professional fees of $28,845
included in Other Accrued Expenses and Liabilities that exceeded 5% of total
liabilities on the Statement of Assets and Liabilities.

NOTE 7 -- CONCENTRATION OF INVESTMENT RISKS

FOREIGN SECURITIES. The Trust may invest in foreign securities and has a policy
of investing in the securities of companies that own or develop natural
resources and other basic commodities, or supply goods and services to such
companies. There are certain risks involved in investing in foreign securities
or concentrating in specific industries such as natural resources that are in
addition to the usual risks inherent in domestic investments. These risks
include those resulting from future adverse political and economic developments,
as well as the possible imposition of foreign exchange or other foreign
governmental restrictions or laws, all of which could affect the market and/or
credit risk of the investments.

NON-DIVERSIFIED. The Portfolio is classified as a non-diversified investment
company under the Investment Company Act, which means that the Trust is not
limited in the proportion of its assets in a single issuer. The investment of a
large percentage of a Trust's assets in the securities of a small number of
issuers may cause the Trust's share price to fluctuate more than that of a
diversified investment company.

NOTE 8 -- LINE OF CREDIT

The Trust, in addition to certain other funds managed by the Investment Manager,
have entered into an unsecured committed revolving line of credit agreement (the
"Credit Agreement") with The Bank of New York for an aggregate amount of
$125,000,000.

    NOTES TO FINANCIAL STATEMENTS as of June 30, 2004 (Unaudited) (continued)

NOTE 8 -- LINE OF CREDIT (CONTINUED)

The proceeds may be used to: (1) temporarily finance the purchase and sale of
securities; (2) finance the redemption of shares of an investor in the funds;
and (3) enable the funds to meet other emergency expenses as defined in the
Credit Agreement. The funds to which the line of credit is available pay a
commitment fee equal to 0.09% per annum on the daily unused portion of the
committed line amount payable quarterly in arrears. The Trust utilized the line
of credit for five days during the six months ended June 30, 2004, with an
approximate average daily balance of $620,000 and an approximate weighted
average interest rate of 1.51%.

NOTE 9 -- CAPITAL SHARE TRANSACTIONS

</Table>

NOTE 10 -- FEDERAL INCOME TAXES

The amount of distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations, which
may differ from accounting principles generally accepted in the United States of
America for investment companies. These book/tax differences may be either
temporary or permanent. Permanent differences are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences are not reclassified. Key differences include the treatment of
short-term capital gains, foreign currency transactions, and wash sale
deferrals. Distributions in excess of net investment income and/or net realized
capital gains for tax purposes are reported as distributions of paid-in capital.

Dividends to shareholders from ordinary income were $249,957 for the six months
ended June 30, 2004. There were no distributions to shareholders during the year
ended December 31, 2003.

Dividends paid by the Trust from net investment income and distributions of net
realized short-term capital gains are, for federal income tax purposes, taxable
as ordinary income to shareholders.

The tax-basis components of distributable earnings and the expiration dates of
the capital loss carryforwards which may be used to offset future realized
capital gains for federal income tax purposes as of December 31, 2003 were as
follows:

</Table>

NOTE 11 -- OTHER INFORMATION

As with many financial services companies, ING Investments and affiliates of ING
Investments (collectively, "ING") have received requests for information from
various governmental and self-regulatory agencies in connection with
investigations related to trading in investment company shares. In each case,
full cooperation and responses are being provided. In addition to responding to
regulatory requests, ING management initiated an internal review of trading in
ING insurance, retirement, and mutual fund products. The goal of this review has
been to identify whether there have been any instances of inappropriate trading
in those products by third parties or by ING investment professionals and other
ING personnel. Additionally, ING reviewed its controls and procedures in a
continuing effort to deter improper frequent trading in ING products. ING's
internal reviews related to mutual fund trading are continuing.

The internal review has identified several arrangements allowing third parties
to engage in frequent trading of mutual funds within our variable insurance and
mutual fund products, and identified other circumstances where frequent trading
occurred despite measures taken by ING intended to combat market timing.

In addition, the review has identified five arrangements that allowed frequent
trading in certain ING Funds. ING entities did not receive special benefits in
return for any of these arrangements, which have all been terminated. The
internal review also identified two investment professionals who engaged in
improper frequent trading in ING Funds. ING will reimburse any ING Fund or its
shareholders affected by inappropriate trading for any improper profits that
accrued to any person who engaged in improper frequent trading for which ING is
responsible.
