                             LETTER TO SHAREHOLDERS

August 19, 1999

Dear Shareholder,
    With the volatility that we've experienced recently in many financial
markets, some investors have sold securities because of uncertainty about where
the markets were going, only to be left rethinking whether they made the right
decision. We've witnessed this kind of market activity numerous times over the
past several years, sparked by concerns such as the impact of the Asian economic
crisis, high stock valuations, or, most recently, the stability of many
high-flying technology companies. While these fears eventually subsided,
investors who may have sold during this period were unable to reap the benefits
of the subsequent rally. That's partly because most of the recent big gains
happened in relatively short periods of time. This kind of volatility--and the
danger of making short-term decisions--highlights the importance of investing
for the long-term, in accordance with your individual financial objectives.
    Although the worst of the Asian crisis appears to be behind us, new concerns
are always emerging. In the coming months, we'll likely hear more about how the
year 2000 computer problem may affect the markets or that we're overdue for a
correction. While the markets could undoubtedly suffer as a result of these or
any number of other events, we encourage you to focus on your long-term
investment goals. Although nothing is certain, history has shown us that over
time, the markets tend to recover--and most investors want to be positioned to
take advantage of any recovery.
    If you have concerns about market volatility or questions about how your
portfolio is structured to respond to these events, we encourage you to contact
your financial advisor. Your advisor can talk with you about sustaining a
long-term investment plan through a variety of market conditions. We hope that
Van Kampen Funds will play an important role as you and your advisor build a
portfolio designed to help you weather what the markets have in store.

Sincerely,

[SIG.]

                               ECONOMIC SNAPSHOT

    The economy continued to experience impressive growth during the past 12
months, but finally began to show signs of moderating toward the end of the
reporting period.

ECONOMIC GROWTH
    The nation's gross domestic product (GDP), which peaked at 6.0 percent in
the fourth quarter of 1998, fell to more sustainable levels in the first and
second quarters of 1999. The unusually strong GDP early in the reporting period
was fueled by an increase in consumer spending, which was attributed to vibrant
consumer confidence as a result of the strong job market. However, economic
growth leveled off in the second quarter of 1999, as did consumer confidence and
retail spending.

EMPLOYMENT ENVIRONMENT
    Throughout the reporting period, unemployment remained low, the number of
jobs grew, and wages rose. The labor market remained especially tight in the
service industry and most urban areas. As a result, the cost of labor as
measured by the Employment Cost Index grew at a surprising rate in July, causing
concerns about the potential for higher inflation in the months ahead.

INFLATION AND INTEREST RATES
    Inflation remained low during most of the reporting period, although a sharp
increase in oil prices contributed to a spike in April's consumer price index
report (CPI). Following this up-tick, the Federal Reserve raised interest rates
0.25 percent on June 30, partially reversing a series of rate decreases from the
fall of 1998. (Editor's Note: The Fed increased rates an additional 0.25 percent
on August 24.)

ECONOMIC OUTLOOK
    We believe the moderate slowdown in growth may continue, bringing the
economy back to historically normal levels. Strong corporate earnings, low
unemployment, and an active housing market should provide some balance against
slower spending and job growth rates.

                          INTEREST RATES AND INFLATION

                          PORTFOLIO MANAGEMENT REVIEW
                       VAN KAMPEN PRIME RATE INCOME TRUST

We recently spoke with the portfolio management team of the Van Kampen Prime
Rate Income Trust about the key events and economic forces that shaped the
markets during the past year. On July 23, 1999, Dennis J. McDonnell, president
and chief operating officer of Van Kampen Investment Advisory Corp., assumed
day-to-day management responsibilities for the Trust.

    Mr. McDonnell has more than 30 years of asset management experience and was
pivotal in Van Kampen's entry into the senior loan business in 1989. He has had
oversight responsibilities for all senior loan fund operations since the Trust's
inception. The following excerpts reflect his views on the Trust's performance
during the 12 months ended July 31, 1999.

   Q  CAN YOU DESCRIBE THE CONDITIONS OF THE SENIOR LOAN MARKET DURING THE PAST
      YEAR?

   A  The second half of 1998 saw considerable volatility across the financial
      markets, but the senior loan market handled the challenging conditions
      quite well. Economic turmoil overseas sparked a credit crunch in the
United States, as banks became more cautious about lending to corporations--many
banks feared that a drop in corporate earnings might hinder the borrowers'
ability to repay their loans. This caution contributed to a slowdown in new
issuance of senior loans. The loans that did come to market carried attractive
yields, as banks required borrowing companies to pay a premium in light of the
uncertain economic environment. In addition, the companies that could afford to
pay these premiums were firms that generally displayed strong fundamentals. This
combination of desirable yields and strong issuers resulted in favorable
opportunities to add to our senior loan portfolio.

    The Federal Reserve Board responded to market conditions with a series of
interest-rate cuts in late 1998. The market's absorption of these cuts in early
1999 coincided with a general recovery among global economies, and these factors
helped alleviate the U.S. credit crunch and accelerate new issuance in the
senior loan market. Surprisingly healthy economic growth and a mild surge in
inflation prompted the Fed to raise rates in June, adding more opportunities to
find attractive yields in the senior loan market. However, the corporate debt
market (including bonds and bank loans) has been experiencing some deterioration
over the last several months, resulting in an increase in the default rate.

   Q  HOW DID CHANGING INTEREST RATES AFFECT THE TRUST'S DIVIDEND?

   A  Senior loans have the ability to adjust their interest payments over time
      in conjunction with changes in interest rates--generally, interest rates
      on loans in the Trust's portfolio reset every 30 to 90 days. As a result,
the income generated by the Trust usually reflects the prevailing trend in
short-term interest rates. During late 1998,

                                        4
<PAGE>   6

many of the Trust's holdings adjusted their interest rates to reflect the
downward trend in short-term rates and the reductions by the Fed. We lowered the
Trust's dividend accordingly on two occasions last fall. In 1999, however,
interest rates have been on the upswing, so we were able to raise the Trust's
dividend in June.

   Q  WHAT AREAS OF THE MARKET OFFERED THE BEST OPPORTUNITIES?

   A  As has been the case for awhile now, we found many opportunities in the
      telecommunications arena--including cellular, wireless, and personal
communications systems. This segment constituted the largest industry weighting
in the portfolio. Telecommunications continues to experience a high level of
merger-and-acquisition activity, for which senior loans have helped provide the
financing. In addition to telecommunications, we had significant positions in
broadcasting and chemicals, plastics, and rubber.

   Q  CAN YOU TALK ABOUT SOME OF YOUR LARGEST HOLDINGS?

   A  Most of the borrowing companies represented in the portfolio provide basic
      goods and services to the domestic economy. Senior loans often provide
      integral financing for the growth and development of these firms.
Currently, we hold more than 310 issues from 47 industry sectors. Among our ten
largest holdings are:

    - Lyondell Petrochemical--An oil refiner and petrochemical maker, Lyondell
      used senior loans to help finance its acquisition of ARCO Chemical in
      1998.

    - Metro-Goldwyn-Mayer (MGM)--This company produces and distributes
      television programs and motion pictures.

    - Charter Communications--This national provider of cable television and
      related telecommunications services is owned by Paul Allen, co-founder of
      Microsoft.

    - Chancellor Broadcasting--This diversified media company has interests in
      radio, outdoor advertising, and television. Chancellor Broadcasting
      continues to benefit from industry deregulation.

    - Safety-Kleen--This firm provides hazardous and industrial waste management
      services, including collection, processing, recycling, and disposal.

    When we purchase senior loans for the Trust's portfolio, we seek companies
that we believe can perform well in the long run and make their loan payments on
schedule. Keep in mind, however, that every loan in the portfolio is subject to
credit risk. A senior loan issuer that finds itself unable to make timely
principal and interest payments is subject to the risk of default or bankruptcy
which would have a negative effect on the Trust's net asset value. For
additional portfolio highlights, please refer to page 9.

                                        5
<PAGE>   7

   Q  WHAT FACTORS WORKED AGAINST THE TRUST?

   A  The portfolio had significant exposure to the health-care industry, which
      underperformed during the reporting period. This exposure negatively
      affected the Trust's performance and earnings. The challenges imposed by
managed care and changing Medicare reimbursement policies caused this area of
the market to struggle, and we believe these challenges will continue to have an
impact on the health-care industry into next year. Despite this turbulence, we
feel confident in the management teams of the borrowing companies in which we've
invested, and we expect them to adapt to the new health-care environment.

    Another factor that negatively affected the Trust's performance was defaults
in certain senior loan holdings.

   Q  HOW DID THE TRUST PERFORM DURING THE REPORTING PERIOD?

   A  The Trust's total return for the 12-month period was 5.23 percent(1) at
      net asset value, and the Trust's current monthly dividend of $0.0535
      represented a distribution rate of 6.48 percent(2). For more information
on the Trust's performance, please refer to the chart and footnotes on page 3.
Past performance does not guarantee future results.

   Q  WHAT IS YOUR OUTLOOK FOR THE SENIOR LOAN MARKET AND FOR THE TRUST?

   A  Looking forward, there are several factors in place that suggest a
      generally favorable environment for senior loans. Strong new issuance
      continues to provide an ample supply of loans, and rising interest rates
have begun to create both increased income potential and increased demand for
senior loan products.

    Nevertheless, we are mindful of deteriorating credit conditions, which may
adversely affect senior loan valuations. In light of the recent rise in defaults
and bankruptcy filings by corporate borrowers, we expect some weakening in the
quality of some existing positions in the portfolio, which could lead to greater
fluctuation in the Trust's net asset value than has been our previous
experience. During the reporting period, the Trust's net asset value fluctuated
between $9.85 and $9.98 per share. (Editor's note: As of September 14, 1999, the
Trust's net asset value was $9.78.) We expect to keep the Trust invested in a
broad variety of industries and individual loans, in our effort to limit the
effects of problems with a particular issuer or industry.

                               GLOSSARY OF TERMS

FEDERAL RESERVE BOARD (THE FED): The governing body of the Federal Reserve
    System, which is the central bank of the United States. Its policy-making
    committee, called the Federal Open Market Committee, meets eight times a
    year to establish monetary policy and monitor the economic pulse of the
    United States.

FUNDAMENTALS: Characteristics of a company, such as revenue growth, earnings
    growth, financial strength, market share, and quality of management.

NET ASSET VALUE (NAV): The value of a mutual fund share, calculated by deducting
    a fund's liabilities from the total assets in its portfolio and dividing
    this amount by the number of shares outstanding. The NAV does not include
    any initial or contingent deferred sales charge.

SENIOR LOANS: Loans or other debt securities that are given preference to junior
    securities of the borrower. In the event of bankruptcy, payments to holders
    of senior loan obligations are given priority over payments to shareholders
    of subordinated debt, as well as shareholders of preferred and common stock.
    Senior loans may share priority status with other senior securities of the
    borrower, and such status is not a guarantee that monies to which the fund
    is entitled will be paid.

                            A FOCUS ON SENIOR LOANS

    The Prime Rate Income Trust invests primarily in senior collateralized loans
to corporations, partnerships, and other business entities that operate in a
variety of industries and geographic locations. Senior loans have a number of
characteristics that, in the opinion of the Trust's management team, are
important to the integrity of the Trust's portfolio. These include:

SENIOR STANDING
    With respect to interest payments, senior loans generally have priority over
other classes of loans, preferred stock, or common stocks, though they may have
equal status with other securities of the borrower. This status is not a
guarantee, however, that monies to which the Trust is entitled will be paid. If
they are not fully paid, it potentially could have a negative effect on the
Trust's net asset value. For more details, please refer to the prospectus.

COLLATERAL BACKING
    Senior loans are often secured by collateral that has been pledged by the
borrower under the terms of a loan agreement. Forms of collateral include
trademarks, accounts receivable or inventory, buildings, real estate,
franchises, and common and preferred stock in subsidiaries and affiliates. Under
certain circumstances, collateral might not be entirely sufficient to satisfy
the borrower's obligations in the event of nonpayment of scheduled interest or
principal, and in some instances may be difficult to liquidate on a timely
basis.
    Additionally, a decline in the value of the collateral could cause the loan
to become substantially undersecured, and circumstances could arise (such as
bankruptcy of a borrower) that could cause the Trust's security interest in the
loan's collateral to be invalidated. This could potentially have a negative
effect on the Trust's net asset value.

CREDIT QUALITY
    Many senior loans carry provisions designed to protect the lender in certain
circumstances. In addition, the variable-rate nature of the portfolio is
expected to lessen the fluctuation in the Trust's net asset value. However, the
net asset value will still be subject to the influence of changes in the real or
perceived credit quality of the loans in which the Trust invests. This may
occur, for example, in the event of a sudden or extreme increase in prevailing
interest rates, a default in a loan in which the Trust holds an interest, or a
substantial deterioration in the borrower's creditworthiness. From time to time,
the Trust's net asset value may be more or less than at the time of the
investment.

SPECIAL CONSIDERATIONS
    Under normal market conditions, the Trust may invest up to 20 percent of its
assets in senior loans that are not secured by any specific collateral. From
time to time, the Trust may hold equity positions as collateral, which may
contribute to volatility in the Trust's net asset value. These equity positions
may or may not be traded on stock exchanges and valued daily at the market
price. It is management's opinion that shareholders will generally ultimately
benefit from these holdings. In addition, up to 20 percent of the Trust's assets
may be invested in senior loans made to non-U.S. borrowers, although these loans
must be U.S.-dollar denominated.

                      PORTFOLIO OF INVESTMENTS (CONTINUED)

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

 *   Senior Loans in the Trust's portfolio generally are subject to mandatory
     and/or optional prepayment. Because of these mandatory prepayment
     conditions and because there may be significant economic incentives for a
     Borrower to prepay, prepayments of Senior Loans in the Trust's portfolio
     may occur. As a result, the actual remaining maturity of Senior Loans held
     in the Trust's portfolio may be substantially less than the stated
     maturities shown. Although the Trust is unable to accurately estimate the
     actual remaining maturity of individual Senior Loans, the Trust estimates
     that the actual average maturity of the Senior Loans held in its portfolio
     will be approximately 18-24 months.

 **  Senior Loans in which the Trust invests generally pay interest at rates
     which are periodically redetermined by reference to a base lending rate
     plus a premium. These base lending rates are generally (i) the lending rate
     offered by one or more major European banks, such as the London Inter-Bank
     Offered Rate ("LIBOR"), (ii) the prime rate offered by one or more major
     United States banks, and (iii) the certificate of deposit rate. Senior
     loans are generally considered to be restricted in that the Trust
     ordinarily is contractually obligated to receive approval from the Agent
     Bank and/or borrower prior to the disposition of a Senior Loan.

                         NOTES TO FINANCIAL STATEMENTS

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Prime Rate Income Trust (the "Trust") is registered as a
non-diversified closed-end management investment company under the Investment
Company Act of 1940, as amended. The Trust's investment objective is to provide
a high level of current income, consistent with preservation of capital. The
Trust seeks to achieve its objective by investing primarily in a portfolio of
interests in floating or variable rate senior loans to United States
corporations, partnerships and other entities. The Trust commenced investment
operations on October 4, 1989.

    The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION--The value of the Trust's Variable Rate Senior Loan
interests and Other Loan interests (collectively "Loan interest") totaling
$7,310,473,755 (89.8% of net assets) is determined by Van Kampen Investment
Advisory Corp. (the "Adviser") following guidelines and procedures established,
and periodically reviewed, by the Board of Trustees. The value of a Loan
interest in the Trust's portfolio is determined with reference to changes in
market interest rates and to the creditworthiness of the underlying obligor. In
valuing Loan interests, the Adviser considers market quotations and transactions
in instruments that the Adviser believes may be comparable to such Loan
interests. In determining the relationship between such instruments and the Loan
interests, the Adviser considers such factors as the creditworthiness of the
underlying obligor, the current interest rate, the interest rate redetermination
period and maturity date. To the extent that reliable secondary market
transactions in Senior Loan interests have occurred, the Adviser also considers
pricing information derived from such secondary market transactions in valuing
Loan interests. Because of uncertainty in the nature of the valuation process,
the estimated value of a Loan interest may differ significantly from the value
that would have been used had there been reliable market activity for that Loan
interest. Equity securities are valued on the basis of prices furnished by
pricing services or as determined in good faith by the Adviser. Short-term
securities with remaining maturities of 60 days or less are

                                       40
<PAGE>   42
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                                 July 31, 1999
- --------------------------------------------------------------------------------

valued at amortized cost. Short-term loan participations are valued at cost in
the absence of any indication of impairment.

B. SECURITY TRANSACTIONS--Investment transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.

C. INVESTMENT INCOME--Dividend income is recorded on the ex-dividend date and
interest income is recorded on an accrual basis. Facility fees on senior loans
purchased are treated as market discounts. Market premiums and discounts are
amortized over the stated life of each applicable security.
    Other income is comprised primarily of amendment fees. Amendment fees are
earned as compensation for agreeing to changes in loan agreements.

D. FEDERAL INCOME TAXES--It is the Trust's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Therefore, no provision for federal income taxes is required.

    The Trust intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset such losses against any future realized capital
gains. At July 31, 1999, the Trust had an accumulated capital loss carryforward
for tax purposes of $29,215,056, which will expire between July 31, 2004 and
July 31, 2007. Net realized gains or losses may differ for financial and tax
reporting purposes primarily as a result of wash sales, post October losses
which may not be recognized for tax purposes until the first day of the
following fiscal year and losses that were recognized for book purposes but not
for tax purposes at the end of the fiscal year.

    At July 31, 1999, for federal income tax purposes cost of long- and
short-term investments is $8,173,783,765, the aggregate gross unrealized
appreciation is $30,113,270 and the aggregate gross unrealized depreciation is
$112,835,166 resulting in net unrealized depreciation on long- and short-term
investments of $82,721,896.

E. DISTRIBUTION OF INCOME AND GAINS--The Trust declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                                 July 31, 1999
- --------------------------------------------------------------------------------

    Due to inherent differences in the recognition of income, expenses and
realized gains/losses under generally accepted accounting principles and federal
income tax purposes, permanent differences between financial and tax basis
reporting for the 1999 fiscal year have been identified and appropriately
reclassified. Permanent differences relating to expenses which are not
deductible for tax purposes totaling $63,610 were reclassified from capital to
accumulated undistributed net investment income.

2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
Under the terms of the Trust's Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Trust for an annual fee payable
monthly as follows:

<TABLE>

Next $2.5 billion.....................................    .875 of 1%
Over $10.0 billion....................................    .850 of 1%
</TABLE>

    In addition, the Trust will pay a monthly administrative fee to Van Kampen
Funds Inc., the Trust's Administrator, at an annual rate of .25% of the average
net assets of the Trust. The administrative services to be provided by the
Administrator include monitoring the provisions of the loan agreements and any
agreements with respect to participations and assignments, record keeping
responsibilities with respect to interests in Variable Rate Senior Loans in the
Trust's portfolio and providing certain services to the holders of the Trust's
securities.

    For the year ended July 31, 1999, the Trust recognized expenses of
approximately $334,000 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Trust, of which a trustee of
the Trust is an affiliated person.

    For the year ended July 31, 1999, the Trust recognized expenses of
approximately $110,300 representing Van Kampen Funds Inc. or its affiliates'
(collectively "Van Kampen") cost of providing legal services to the Trust.

    Van Kampen Investor Services Inc., an affiliate of the Adviser, serves as
the shareholder servicing agent of the Trust. For the year ended July 31, 1999,
the Trust recognized expenses for these services of approximately $5,333,400.
Transfer agency fees are determined through negotiations with the Trust's Board
of Trustees and are based on competitive market benchmarks.

    Certain officers and trustees of the Trust are also officers and directors
of Van Kampen. The Trust does not compensate its officers or trustees who are
officers of Van Kampen.
    The Trust provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable for a ten-year period
and are based upon each trustee's years of service to the Trust. The maximum
annual benefit per trustee under the plan is $2,500.
    During the period, the Trust owned shares of the following affiliated
companies. Affiliated companies are defined by the Investment Company Act of
1940 as those companies in which a fund holds 5% or more of the outstanding
voting securities.

$500,000,000, which will terminate on June 13, 2000. The proceeds of any
borrowing by the Trust under the revolving credit agreement may only be used,
directly or indirectly, for liquidity purposes in connection with the
consummation of a tender offer by the Trust for its shares. Annual commitment
fees of .09% are charged on the unused portion of the credit line. Borrowings
under this facility will bear interest at either the LIBOR rate or the Federal
Funds rate plus .45%, except during the period from December 17, 1999 through
January 14, 2000, the applicable margin shall be .575%. There have been no
borrowings under this agreement to date.

8. SENIOR LOAN PARTICIPATION COMMITMENTS
The Trust invests primarily in participations, assignments, or acts as a party
to the primary lending syndicate of a Variable Rate Senior Loan interest to
United States corporations, partnerships, and other entities. When the Trust
purchases a participation of a Senior Loan interest, the Trust typically enters
into a contractual agreement with the lender or other third party selling the
participation, but not with the borrower directly. As such, the Trust assumes
the credit risk of the borrower, Selling Participant or other persons
interpositioned between the Trust and the borrower.

    At July 31, 1999, the following sets forth the selling participants with
respect to interests in Senior Loans purchased by the Trust on a participation
basis.

                       REPORT OF INDEPENDENT ACCOUNTANTS

The Board of Trustees and Shareholders of
Van Kampen Prime Rate Income Trust:

We have audited the accompanying statement of assets and liabilities of Van
Kampen Prime Rate Income Trust (the "Trust"), including the portfolio of
investments as of July 31, 1999, and the related statements of operations and
cash flows for the year then ended, the statement of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the periods presented. These financial statements and financial
highlights are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of July
31, 1999, by correspondence with the custodian and selling or agent banks; where
replies were not received we performed other auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to

                         YEAR 2000 READINESS DISCLOSURE

Like other mutual funds, financial and business organizations and individuals
around the world, the Trust could be adversely affected if the computer systems
used by the Trust's investment adviser and other service providers do not
properly process and calculate date-related information and data from and after
January 1, 2000. This is commonly known as the "Year 2000 Problem." The Trust's
investment adviser is taking steps that it believes are reasonably designed to
address the Year 2000 Problem with respect to computer systems that it uses and
to obtain reasonable assurances that comparable steps are being taken by the
Trust's other major service providers. At this time, there can be no assurances
that these steps will be sufficient to avoid any adverse impact to the Trust. In
addition, the Year 2000 Problem may adversely affect the markets and the issuers
of securities in which the Trust may invest that, in turn, may adversely affect
the net asset value of the Trust. Improperly functioning trading systems may
result in settlement problems and liquidity issues. In addition, corporate and
governmental data processing errors may result in production problems for
individual companies or issuers and overall economic uncertainty. Earnings of
individual issuers will be affected by remediation costs, which may be
substantial and may be reported inconsistently in U.S. and foreign financial
statements. Accordingly, the Trust's investments may be adversely affected. The
statements above are subject to the Year 2000 Information and Readiness
Disclosure Act, which may limit the legal rights regarding the use of such
statements in the case of dispute.
