January 5, 1998

Dear Shareholder,

     On August 4, 1997, the announcement of exchange privileges between Van
Kampen American Capital and Morgan Stanley funds opened the door to even greater
investment opportunities. We are proud to offer an expanded family of mutual
funds covering virtually every market and continent. In our view, the rapid
appreciation of U.S. stock prices in recent years has created a need for
investors to examine their portfolios carefully to ensure proper diversification
among domestic and foreign investments. The Morgan Stanley funds, with their
emphasis on global markets, can be valuable tools for accomplishing this
diversification.

Economic Overview

     Solid growth and robust job creation continued to characterize the U.S.
economic environment during the reporting period. The nation's output of goods
and services during the first quarter grew at its fastest pace in nine years.
Meanwhile, unemployment fell to 4.6 percent of the workforce in November, its
lowest level since October 1973.

     Despite the thriving labor market and the rapid pace of economic activity,
there was little evidence of inflation. Wholesale prices actually fell during
each of the first seven months of 1997, the longest stretch of consecutive
monthly declines in history. At the consumer level, prices increased by 1.8
percent over the 12 months through November.

     Several factors contributed to keeping inflation in check. A strong rally
in the U.S. dollar helped limit price increases on imported goods. Also, a sharp
acceleration in productivity gains allowed employers to offset the cost of
higher salaries without significantly raising prices.

     The inflationary implications of the nation's low unemployment rate caused
the Federal Reserve Board to raise short-term interest rates by 0.25 percent in
March. Signs that economic growth slowed modestly during the second and third
quarters, however, led Fed policy-makers to leave interest rates unchanged for
the rest of the year.

Market Review

     Long-term interest rates fluctuated modestly during the reporting period.
As the U.S. economy strengthened early in the year, the yield on the Treasury's
benchmark 30-year bond climbed to 7.17 percent in mid-April amid fears of higher
inflation. (As bond yields climb, bond prices fall.) When those concerns proved
unfounded, Treasury bond yields gradually fell back to 6.04 percent by the end
of the reporting period. The widespread devaluation of Asian currencies also
helped to spark demand for fixed-income investments by increasing the likelihood
that inflation in the U.S. would remain under control.

     Treasury bonds in particular were aided by a global "flight to quality" as
the economic crisis in Asia and related equity-market turbulence made government
securities an increasingly attractive alternative. The outperformance of
Treasury bonds late in the reporting period allowed the yield spread between
taxable and tax-exempt securities to narrow. For example, the Bond Buyer
Municipal Revenue Bond yield as a percentage of the 30-year Treasury-bond yield
rose from approximately 88 percent in September to approximately 91 percent in
November. At the close of the reporting period, long-term AAA-rated

                                                           Continued on page two

                                       1
<PAGE>
 
general obligation bonds provided a yield of 5.13 percent, which is equivalent
to a 7.43 percent yield on a taxable security for an investor in the 31 percent
federal income-tax bracket.

     The decline in inflationary expectations helped to make long-term bonds the
best-performing sector of the tax-exempt market. In the 12 months ended November
30, long-term general obligation bonds returned over nine percent, compared to
less than eight percent for intermediate-term issues.


Outlook

     We expect that the recent upheaval in Southeast Asia will have a mixed
impact on the domestic economy and a generally positive effect on fixed-income
investments. Reduced demand for American exports to Asia will exert a mild drag
on the U.S. economy in coming months. But while corporate profits could suffer,
slower economic growth will help to mitigate the inflationary pressures caused
by the strong domestic labor market. Also, we believe that lower currency values
in Asia will result in less inflation in the U.S. and a greater likelihood of
stable or falling interest rates. This scenario is especially favorable for 
high-quality bonds over the long term.

     If bond yields continue to drift lower, economic growth in the United
States could accelerate later in the year. We believe that the Federal Reserve
would respond to any significant pickup in economic activity with a moderate
increase in short-term interest rates. We also expect the healthy economy to
keep credit spreads relatively tight in coming months.

     The new economic environment must be viewed against a backdrop in which
financial asset prices have appreciated substantially in recent years. The
return of significant volatility to global equity markets in recent months is a
reminder of the ongoing need to monitor your portfolio carefully for proper
diversification among asset classes. We urge our fund shareholders to use this
opportunity to consider how their holdings are currently divided among the three
major asset classes of stocks, bonds, and cash. Uneven moves in the various
markets can distort a carefully planned investment program. We encourage you to
review your portfolio with an eye toward correcting imbalances in the way your
assets are allocated.

Sincerely,

                Putting Your Fund's Performance in Perspective


     As you evaluate your progress toward achieving your financial goals, it is
important to track your investment portfolio's performance at regular intervals.
A good starting point is a comparison of your investment holdings to an
applicable benchmark, such as a broad-based market index. Such a comparison can:

     . Illustrate the general market environment in which your investments are 
       being managed

     . Reflect the impact of favorable market trends or difficult market
       conditions

     . Help you evaluate the extent to which your Fund's management team has 
       responded to the opportunities and challenges presented to them over the
       period measured

     For these reasons, you may find it helpful to review the chart below, which
compares your Fund's performance to that of the Lehman Brothers Municipal Bond
Index over time.  As a broad-based, unmanaged statistical composite, this index
does not reflect any commissions or fees which would be incurred by an investor
purchasing the securities it represents.  Similarly, its performance does not
reflect any sales charges or other costs which would be applicable to an
actively managed portfolio, such as that of the Fund.

shareholders investing in the different share classes.  The Fund's performance
assumes reinvestment of all distributions and includes payment of the maximum
sales charge (4.75% for A shares).

                          Portfolio Management Review


             Van Kampen American Capital High Yield Municipal Fund

We recently spoke with the management team of the Van Kampen American Capital
High Yield Municipal Fund about the key events and economic forces that shaped
the markets during the Fund's fiscal year. The team includes Wayne D. Godlin,
portfolio manager, and Peter W. Hegel, chief investment officer for fixed-income
investments. The following excerpts reflect their views on the Fund's
performance during the 12-month period ended November 30, 1997.

Q   How would you describe the market environment in which the Fund has
    operated during the past 12 months?

A   The bond market saw healthy advances in price during the first 11 months of
    1997, but this ascension was not a smooth ride. Early in the year, when 
economic indicators fueled concerns about rising inflation and a potential
interest rate hike by the Federal Reserve Board, bond prices began to fall. When
the Fed did raise interest rates by a modest 0.25 percent in late March, bond
prices fell further. By mid-April, however, the market's mood reversed, showing
few signs of price pressures despite the economy's strength. Bond prices also
benefited from continued heavy purchases by foreign investors and concerns that
the stock market rally was nearing an end.

    As the economy continued to show few if any signs of inflation, long-term
interest rates declined further. This caused credit spreads between investment-
grade and lower- or non-rated bonds to contract significantly. We also saw an
unprecedented amount of insured bond issuance, which has reduced the supply of
higher-yielding, lower- and non-rated bonds available in the market.

Q   Have these conditions affected the management of the Fund?

A   The Fund's investment strategy did not change based on what happened in the
    market this year. Instead, we evaluated bond issues on an individual basis
and made purchases where we found the most appropriate opportunity. This
strategy is referred to as a 'bottom-up' approach to bond selection.

    The narrowing of credit spreads, while limiting the attractiveness of the
high-yielding, high-risk securities, actually increased the value of the lower-
and non-rated bonds held in the Fund's portfolio. We found bonds in the 15- to
20-year maturity range the most attractive for maintaining the Fund's yield. The
Fund typically maintains a greater percentage of assets in higher-yielding,
lower-rated securities than other funds in its peer group.  Currently, the Fund
holds over 70 percent in non-investment grade securities. By relying heavily on
our research and analysis to find attractive high-yielding issues, we are able
to consistently provide shareholders with a higher level of income potential.

Q   What changes have you made to the portfolio?

A   Turnover in the Fund has remained relatively low, staying within a range 
    of 20 to 25 percent over the reporting period. We continued to allocate the
Fund's assets according to the stringent credit standards we've established. Our
sector weightings are a reflection of where we found opportunities on a bond by
bond basis. Health care and senior housing issues, namely Continuing Care
Retirement Centers (CCRC), represent two areas of interest for the portfolio.
CCRCs provide housing, activities, and nursing services for elderly and retired
individuals. Our health care holdings include several long-term care and acute
care centers.

    The CCRCs have gained prominence as part of our portfolio holdings during
the reporting period. As the population lives longer and the number of people at
retirement age increases, the need for continuing care will naturally expand.
Our CCRC holding--19.0 percent of the Fund's total assets--includes centers in
Pennsylvania, New Jersey, and Arizona. These issues performed well during the
reporting period.

    The duration of the Fund remained at approximately 5.75 to 6.00 years, and
ended the 12-month period at 5.94 years.  In order to minimize volatility, we
typically maintain the Fund's duration in this range. Rather than trying to time
the market, we concentrated on maintaining a balanced portfolio that we feel
will perform well during both upward and downward swings in interest rates. For
additional Fund portfolio highlights, please refer to page four.

Q   How did the Fund perform during the reporting period?

A   The Fund posted positive results for the fiscal year.  Total return for the
    12 months ended November 30, 1997 was 9.63 percent/1/ (Class A shares at 
net asset value), and the Fund's net asset value closed the period at $11.45 per
Class A share, up 3 percent from $11.14 per Class A share at the beginning of
the fiscal year. The Fund's tax-exempt distribution rate as of November 30,
1997, was 5.99 percent/3/, representing a taxable-equivalent distribution rate
of 9.36 percent/4/ for an investor in the 36-percent federal income tax bracket.

    The Fund's total return compared favorably to that of the Lehman Brothers
Municipal Bond Index, which returned 7.17 percent over the same period. This
index is a broad-based, unmanaged index of municipal bonds and does not reflect
any commissions or fees that would be paid by an investor purchasing the
securities it represents. Please refer to the chart on page three for additional
Fund performance results.

    In addition to its favorable return, the Fund received an overall rating of
five stars from Morningstar, among 1,481 funds in the Municipal Bond Category.
This five-star composite rating is the highest rating assigned by Morningstar
and is evaluated on a monthly basis.  Morningstar is an independent rating
company that reviews and assigns ratings to mutual funds.* While past
performance is no guarantee of future results, Morningstar ratings provide a
means to measure a fund's ability to achieve its investment goals. The ratings
calculate the funds' three-, five-, and ten-year average annual returns with 10
percent of the funds in a category receiving five stars, 22.5 percent receiving
four stars, 35 percent receiving three stars, 22.5 percent receiving two stars,
and 10 percent receiving one star. The fund was rated among 1,481 funds, 695
funds, and 332 funds and received five-star ratings for the three-, five-, and
ten-year periods, respectively.

Q   What is your outlook for the months ahead?

A   We expect that interest rates will remain fairly stable into 1998.  As
    inflation continues to appear under control, the Fed will not likely raise
rates at their first meeting in February 1998. If economic indicators begin to
show signs of inflation, we believe the Fed will respond with a small rate
increase midway through 1998.

    We believe the Fund is well positioned to weather changes in interest rates
in the coming year. We would like to see credit spreads widen in the new year,
but all indicators lead us to believe that spreads will remain tight for the
foreseeable future. Regardless, thanks to our relatively low duration and our
'bottom-up' approach to bond selection, we feel the Fund will be less volatile
to any upward or downward changes in interest rates. In conclusion, we are
confident that the securities we've chosen are consistent with the stringent
standards we set for the portfolio.

                               Glossary of Terms


Basis point:

     A measure used in quoting yields on bonds. One hundred basis points is
equal to one percent. For example, if a bond's yield changes from 7.00 to 6.65
percent, it would be considered a 35 basis point move.

Call feature:

     Allows the issuer to buy back the bond before the date of maturity. When
the bond is called, the issuer repurchases it at or above its face value, and
stops paying interest on that loan.

Class A shares:

     When Class A shares of a fund are purchased, the share price includes the
net asset value plus a one-time sales charge (or "load"). There is no redemption
fee (Contingent Deferred Sales Charge).

Coupon rate:

     The stated rate of interest the bond pays until maturity, expressed as a
percentage of the face value.

Credit spread:

     Also called quality spread, the difference in yield between higher-quality
issues (such as AAA-rated municipal securities) and lower-quality issues (such
as BBB- and non-rated municipal bonds). Under normal circumstances, lower-
quality issues provide higher yields in order to compensate investors for the
additional credit risk.

Duration:

     A measure of a bond's sensitivity to changes in interest rates, expressed
in years. The longer a fund's duration, the greater the effect of interest rate
movements on net asset value. Typically, funds with shorter durations have
performed better in rising rate environments, while funds with longer durations
have performed better when rates decline.

Federal funds rate:

     The interest rate charged by one institution lending federal funds to
another. This overnight rate is used to meet banks' daily reserve requirements.
The Federal Reserve Board uses the federal funds rate to affect the direction of
interest rates.

Federal Reserve Board (The Fed):

     A seven-member group that directs the operations of the Federal Reserve
System, the central bank system of the United States. Currently led by Chairman
Alan Greenspan, the Fed meets eight times a year to establish monetary policy
and monitor the country's economic pulse.

General obligation bonds:

     Bonds backed by the full faith and credit (taxing authority) of the issuer
for timely payment of interest and principal.  General obligation bonds are
issued to finance essential government projects, such as highways and schools.

Inflation:

          An economic state in which the amount of money supply and business
activity dramatically increases, accompanied by sharply rising prices. Inflation
is widely measured by the Consumer Price Index, a leading economic indicator
that measures the change in the cost of purchased goods and services.

Municipal bond:

     A debt security issued by a state, municipality, or other governmental
entity to finance capital expenditures. Such expenditures might include the
construction of highways, public works, or school buildings.

Municipal revenue bonds:

     Bonds that are payable only from the revenues the project will generate and
are not backed by any taxing authority of the issuer.  Revenue bonds are issued
to finance the building of hospitals, toll bridges, electric dams, airports, and
college dormitories.

Municipal yield curve:

     A representation of the actual or projected yields of municipal bond
securities in relationship to their maturities.

Net asset value (NAV):

     The value of a mutual fund share, calculated by deducting a fund's
liabilities from its total assets and dividing this amount by the number of
shares outstanding.  The NAV does not include any initial or contingent deferred
sales charges.

Put bond:

     A long-term bond that the bondholder can "put" back to the issuer for
redemption at a specified price on a specified future date prior to maturity.

Refunding:

     A process whereby new bonds are issued to refinance an outstanding bond
issue. This typically occurs when interest rates decline and an issuer wishes to
replace higher-yielding bonds with current lower-yielding issues.

Yield curve:

     A result of viewing the yields of U.S. Treasury securities maturing in 1,
5, 10, and 30 years, grouped together, will often reflect a pattern of
increasing yield as maturity extends. This pattern creates an upward sloping
"curve." A "flat" yield curve represents little difference between short- and
long-term interest rates. An "inverted" yield curve indicates that short-term
rates are rising as long-term rates move lower.

Zero coupon bonds:

     A corporate or municipal debt security traded at a deep discount from face
value that pays no interest and it may be redeemed at maturity for full face
value.

1. Significant Accounting Policies

Van Kampen American Capital High Yield Municipal Fund (the "Fund") is organized
as a series of the Van Kampen American Capital Tax-Exempt Trust, a Delaware
business trust, and is registered as a diversified open-end management
investment company under the Investment Company Act of 1940, as amended. The
Fund's investment objective is to provide as high a level of interest income
exempt from federal income tax as is consistent with investing in medium- to
lower-rated high yielding municipal securities. The Fund commenced investment
operations on January 2, 1986. The distribution of the Fund's Class B and Class
C shares commenced on July 20, 1992 and December 10, 1993, respectively.

     The following is a summary of significant accounting policies consistently
followed by the Fund 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 Valuations--Municipal bonds are valued by independent pricing
services or dealers using the most recently quoted bid price or, in the absence
of market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services are valued at fair value
using procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost.

     The Fund's investments include lower-rated and unrated debt securities
which may be more susceptible to adverse economic conditions than investment
grade holdings. These securities are often subordinated to the prior claims of
other senior lenders and uncertainties exist as to an issuer's ability to meet
principal and interest payments. Securities rated below investment grade and
comparable unrated securities represented approximately 73% of the Fund's
investment portfolio at the end of the period.

B.  Security Transactions--Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when issued" or "delayed delivery"
basis, with settlement to occur at a later date. The value of the security so
purchased is subject to market fluctuations during this period. The Fund will
maintain, in a segregated account with its custodian, assets having an aggregate
value at least equal to the amount of the when issued or delayed delivery
purchase commitments until payment is made.

     The Fund may invest in repurchase agreements, which are short-term
investments in which the Fund acquires ownership of a debt security and the
seller agrees to repurchase the security at a future time and specified price.
The Fund may invest independently in repurchase agreements, or transfer
uninvested cash balances into a pooled cash account along with other investment
companies advised by Van Kampen American Capital Asset Management, Inc. (the
"Advisor") or its affiliates, the daily aggregate of which is invested in
repurchase agreements. Repurchase agreements are fully collateralized by the
underlying debt securities. The Fund will make payment for such securities only
upon physical delivery or evidence of book entry transfer to the account of the
custodian bank. The seller is required to maintain the value of the underlying
security at not less than the repurchase proceeds due the Fund.

C.  Investment Income--Interest income is recorded on an accrual basis. Bond
premium and original issue discount are amortized over the life of each
applicable security.

D. Federal Income Taxes--It is the Fund'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.

                   Notes to Financial Statements (Continued)

                               November 30, 1997
- --------------------------------------------------------------------------------

     The Fund 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 these losses against any future realized capital
gains. At November 30, 1997, the Fund had an accumulated capital loss
carryforward for tax purposes of $23,896,048 which expires between November 30,
1998 and November 30, 2005. Of this amount, $192,128 will expire in 1998. Net
realized gains or losses differ for financial reporting and tax purposes
primarily as a result of the deferral of post October 31 losses which are not
recognized for tax purposes until the first day of the following fiscal year and
gains or losses recognized for tax purposes on open futures positions at
November 31, 1997.

     At November 30, 1997, for federal income tax purposes, cost of long- and
short-term investments is $1,225,423,763; the aggregate gross unrealized
appreciation is $68,669,479 and the aggregate gross unrealized depreciation is
$3,899,421, resulting in net unrealized appreciation of $64,770,058.

E. Distribution of Income and Gains--The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually. Permanent book and tax basis differences relating to the
expiration of a portion of the capital loss carryforward totaling $2,674,127
were reclassified from net realized gain/loss on securities to capital.
Additionally, permanent differences relating to the recognition of expenses
associated with the consolidation of the VKAC open-end fund complex totaling
$14,032 were reclassified from accumulated undistributed net investment income
to capital.

     For the year ended November 30, 1997, 99.99% of the income distributions
made by the Fund were exempt from federal income taxes. In January, 1998, the
Fund will provide tax information to shareholders for the 1997 calendar year.

2. Investment Advisory Agreement and Other Transactions with Affiliates

Under the terms of the Funds Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Fund for an annual fee payable
monthly as follows:

<TABLE>

<S>                                                                  <C>

Next $300 million...................................................   .55 of 1%

</TABLE> 

     The Adviser agreed to reimburse the Fund for certain trustees' compensation
in connection with the July, 1995 increase in the number of trustees of the
Fund. This reimbursement was effective through December 31, 1996.

     For the year ended November 30, 1997, the Fund recognized expenses of
approximately $41,900 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Fund, of which a trustee of the
Fund is an affiliated person.

     For the year ended November 30, 1997, the Fund recognized expenses of
approximately $240,500 representing Van Kampen American Capital Distributors,
Inc.'s or its affiliates' (collectively "VKAC") cost of providing accounting
services to the Fund. These services are provided by VKAC at cost.

     ACCESS Investor Services, Inc., an affiliate of the Adviser, serves as the
shareholder servicing agent for the Fund. For the year ended November 30, 1997,
the Fund recognized expenses of approximately $643,900, representing ACCESS'
cost of providing transfer agency and shareholder services plus a profit.

     Certain officers and trustees of the Fund are also officers and directors
of VKAC. The Fund does not compensate its officers or trustees who are officers
of VKAC.

                               November 30, 1997
- --------------------------------------------------------------------------------

     The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of VKAC. 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 under the plan is equal to $2,500.

3. Capital Transactions

The Fund has outstanding three classes of shares of beneficial interest, Classes
A, B and C, each with a par value of $.01 per share. There are an unlimited
number of shares of each class authorized. At November 30, 1997, capital
aggregated $757,169,936, $410,171,761 and $88,150,812 for Classes A, B, and C,
respectively. For the year ended November 30, 1997, transactions were as

     Class B and C shares are offered without a front end sales charge, but are
subject to a contingent deferred sales charge (CDSC). The CDSC will be imposed
on most redemptions made within five years of the purchase for Class B and one
year of the purchase for Class C as detailed in the following schedule. The
Class B and C shares bear the expense of their respective deferred sales
arrangements, including higher distribution and service fees and incremental
transfer agency costs.

5. Derivative Financial Instruments

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

     The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in the unrealized
appreciation/depreciation on securities. Upon disposition, a realized gain or
loss is recognized accordingly, except when exercising an option contract or
taking delivery of a security underlying a futures contract. In these instances
the recognition of gain or loss is postponed until the disposal of the security
underlying the option or futures contract.

     During the period the Fund invested in future contracts, a type of
derivative. A futures contract is an agreement involving the delivery of a
particular asset on a specified future date at an agreed upon price. The Fund
generally invests in futures on U.S. Treasury Bonds and the Municipal Bond Index
and typically closes the contract prior to the delivery date. These contracts
are generally used to manage the portfolio's effective maturity and duration.

     Upon entering into future contracts, the Fund maintains, in a segregated
account with its custodian, securities with a value equal to its obligation
under the futures contracts. During the period the futures contract is open,
payments are received from or made to the broker based upon changes in the value
of the contract (the variation margin).

     Transactions in futures contracts for the year ended November 30, 1997,
were as follows:

6. Distribution and Service Plans

The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940 and a service plan (collectively
the "Plans"). The Plans govern payments for the distribution of the Fund's
shares, ongoing shareholder services and maintenance of shareholder accounts.

     Annual fees under the Plans of up to .25% for Class A net assets and 1.00%
each for Class B and Class C net assets are accrued daily. Included in these
fees for the year ended November 30, 1997, are payments to VKAC of approximately
$3,006,800.

                       Report of Independent Accountants


To the Shareholders and Board of Trustees of
Van Kampen American Capital High Yield Municipal Fund

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Van Kampen American Capital High
Yield Municipal Fund (the "Fund"), a series of the Van Kampen American Capital
Tax-Exempt Trust, at November 30, 1997, and the results of its operations, the
changes in its net assets and the financial highlights for each of the periods
presented, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at
November 30, 1997 by correspondence with the custodian and brokers and the
application of alternative auditing procedures where confirmations from brokers
were not received, provide a reasonable basis for the opinion expressed above.
