March 27, 1998 

Dear Shareholder, 

     We have begun what promises to be an exciting and challenging year for
investors. The Taxpayer Relief Act of 1997, signed into law by President Clinton
in August, creates many new opportunities for you and your family to take a more
active role in achieving your long-term financial goals.

     Most Americans will benefit from the bill's $95 billion in tax cuts over
five years. The so-called Kiddie Credit gives parents $400 in immediate tax
relief for every child under age 17, and families will find it easier to save
for their children's college expenses through the new Education IRA. The bill
also cuts capital gains tax rates for the first time in over a decade and
loosens restrictions on tax-deductible IRA contributions. Perhaps the most
exciting feature is the new Roth IRA, which allows investment earnings to grow
tax free, not just tax deferred.

     This year more than ever, it could be important for you to talk with your
financial adviser about how to make the tax code work to your advantage. At Van
Kampen American Capital, we have prepared a variety of publications to help you
understand your choices under the new tax legislation. And with the help of your
adviser, we'll work with you to locate the many benefits hidden among the
changing tax landscape.

Economic Overview 

     The nation's economic report card continues to register nearly perfect
grades. Growth is strong, unemployment is low, the budget is headed for surplus,
and the dollar is rising around the world. With the economy running on all
cylinders, consumer confidence soared to a 30-year high in February.

     Despite the strength in the economy, inflation remained under control. The
producer price index actually fell by 1.6 percent during the 12 months through
February. Inflation at the consumer level also was virtually nonexistent, with
the consumer price index rising by only 1.4 percent during the same period. A
strong dollar and significant productivity gains helped offset inflationary
pressures caused by rising wages.

     The Federal Reserve Board left monetary policy unchanged during the six-
month reporting period. In addition to signs that the economy was slowing
modestly from its breakneck pace of early 1997, Fed policy-makers were concerned
about the impact that higher U.S. interest rates might have on the struggling
economies of Southeast Asia. Generally, higher U.S. interest rates cause the
dollar to rise relative to other currencies. With nearly all Asian currencies
already down significantly, a hike in U.S. rates would force monetary
authorities in Asia to choose between letting their currencies decline further
or matching the rate increase, thereby slowing their already-sluggish economies.

     As the reporting period ended, there was little evidence that the Asian
crisis had negatively impacted the U.S. economy. The nation's total output of
goods and services (gross domestic product) grew at a rate of 3.9 percent in the
fourth quarter of 1997, and corporate profits remained strong. A modest pickup
in bond yields in mid-January indicated that global investors were


                                       1                   Continued on page two

increasingly confident that the U.S. economy would escape significant damage
from the slowdown in Asia.

Market Overview 

     Aided by benign inflation at home and an economic crisis overseas, all
sectors of the fixed-income market posted solid returns. In particular, a global
"flight to quality" amid the turmoil in Asia pushed long-term interest rates
sharply lower during the later stages of the reporting period. In the six months
through February, the Merrill Lynch Domestic Master Index gained 5.77 percent.

     The yield on the Treasury's benchmark 30-year bond declined from 6.60
percent at the end of August to 5.66 percent in mid-January as global investors
sought safety in the highly-liquid Treasury market. Demand for fixed-income
securities also increased as investors believed that fallout from the Asian
crisis would slow the U.S. economy enough to keep inflation from rising. But as
evidence indicated that economic growth remained strong, yields on long-term
Treasury bonds rebounded to close the reporting period at 5.91 percent.

     Favorable news about inflation and concerns about Asia combined to make
high-quality long-term bonds the top-performing sector of the fixed-income
market during the reporting period. Long-term Treasury securities gained 10.86
percent for the six months ended in February, compared to 8.04 percent for long-
term corporate issues. Meanwhile, worries that the Asian crisis could lead to an
economic slump in the United States caused modest underperformance among high-
yield bonds, especially during the last quarter of 1997.

Outlook 

     We believe that reduced demand for American exports to Asia and intense
price competition from imports will exert a mild drag on the U.S. economy in
coming months. But while corporate profits could suffer in the near term, slower
economic growth should help to mitigate the inflationary pressures caused by the
tight domestic labor market. That scenario is good for fixed-income investments.

     However, if bond yields continue to drift lower, economic growth in the
U.S. could reaccelerate later in 1998. In recent years, each significant decline
in long-term interest rates has ignited economic growth by making houses, cars,
and other big-ticket consumer goods more affordable. We believe the Federal
Reserve would respond to any significant pickup in economic activity with a
modest increase in short-term interest rates. We also expect the healthy economy
to keep credit spreads relatively tight in coming months.

     As we noted earlier, the Taxpayer Relief Act of 1997 provides attractive
new vehicles through which investors can save for a variety of goals, including
higher education and retirement. We encourage you to work with your financial
adviser to consider how the tax changes can work to your benefit.

     Additional details about your Fund, including a question-and-answer section
with your portfolio management team, are provided in this report. As always, we
are pleased to have the opportunity to serve you through our diverse menu of
quality investments.

                               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 is a 35 basis point move. Sometimes referred to as a percentage
  point.

Credit spread:

  Also called quality spread, the difference in yield between higher-quality
  issues (such as Treasury securities) and lower-quality issues. 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 (Fed):

  A seven-member group that oversees 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.

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.

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
  charge.

Premium redemption:

  The redemption of a bond at a dollar amount above a stated par value, or the
  redemption of a bond by the issuer prior to its maturity date.

Yankee bonds:

  U.S. dollar-denominated bonds issued in the United States by foreign
  governments, banks, and corporations.

                                       4
<PAGE>
 
Yield:

  The annual rate of return on an investment, expressed as a percentage. For
  bonds and notes, the yield is the annual interest divided by the market price.

Yield curve:

  A result of viewing the yields of U.S. Treasury securities maturing in 1, 5,
  10, and 30 years, grouped together, which often reflects 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.

Yield spread:

  The difference in yields between low-quality fixed-income investments and 
  high-quality fixed-income investments. To compensate investors for the added
  risk, low-quality fixed-income securities typically offer investors higher
  yields than high-quality fixed-income securities. The resulting spread is
  commonly expressed in basis points.

                          Portfolio Management Review
- --------------------------------------------------------------------------------

          Van Kampen American Capital High Income Corporate Bond Fund

We recently spoke with the management team of the Van Kampen American Capital
High Income Corporate Bond Fund about the key events and economic forces that
shaped the markets during the past six months. The team includes Ellis S.
Bigelow, 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 six-month period ended February 28, 1998.

Q    How would you characterize the market conditions in which the Fund operated
     during the reporting period?

A    In the past six months, the bond market was most significantly affected by
     a single event: the Asian currency crisis. Although Southeast Asian markets
began to show weakness in August, currency volatility reached a point of chaos
in late October. This situation negatively affected emerging market debt and
caused domestic yields to fall. By the last week of October, the difference in
yield between high yield paper and Treasuries had expanded dramatically, as many
foreign and U.S. investors sought the relative safety and liquidity of U.S.
Treasuries. Spreads narrowed somewhat by the end of the year but were still
wider than they were in August, due to concerns that Asian weakness would
precipitate a slowdown in the U.S. economy.

     For the six-month period ended February 28, 1998, the yield of the
benchmark 10-year Treasury declined 72 basis points, ending the period with a
5.62 percent yield. At the same time, the three-month Treasury yield actually
increased from 5.22 percent on August 31, 1997, to 5.31 percent on February 28,
1998. This produced a considerable flattening of the yield curve--a narrowing of
the difference between long- and short-term bond yields. This scenario often
occurs when market sentiment believes that interest rates could fall, which in
this case was a response to an economic slowdown resulting from the Asian
crisis.

     The high yield market has continued to benefit from relatively strong
technical conditions against this backdrop of volatility. By the end of 1997,
the market boasted record levels of new issuance, and more than $22 billion in
new high yield bonds was issued in the first few months of this year. This
growth in supply has been met with continued high demand. As a result, the high
yield market has nearly doubled in size between 1994 and 1997.
 
Q    How did you manage the Fund in light of these conditions?

A    The investment policy changes that we instituted last year have enabled us
to better address current trends in the marketplace. As stated in your
prospectus, those changes allow us to expand the portfolio's holdings in
investments issued by overseas corporations. More than approximately 20 percent
of all 1997 new issues were non-domestic, reflecting a continuing increase in
international debt. We added several attractive new issues from South America,
Mexico, and Poland to the Fund's portfolio. We also increased the Fund's
holdings in British cable companies, which have performed quite well. In spite
of these additions, the Fund's non-domestic component was slightly smaller than
its August percentage, because we eliminated the Fund's holdings in Southeast
Asia during the reporting period. We continue to watch emerging markets for new
investment opportunities.

     Nearly half of all new issues in 1997 were contained in the media and
communications industries, and this growth is reflected in the Fund's portfolio.
Aside from the increased exposure in this

                                       6
<PAGE>
 
sector, however, our industry line-up remained fairly steady during the period.
We have maintained a high level of exposure in the raw materials and processing
industry, as well as the consumer services sector. We did reduce the Fund's
exposure to energy issues when we began to see signs of weakness in the sector.
Six months ago, energy accounted for approximately 9 percent of long-term
investments, and it's now approximately 4 percent.

     We continued to overweight the Fund's B-rated sector, although the current
percentage is slightly higher than its level in August. The Fund's BB-rated
holdings have decreased, but CCC-rated securities are relatively unchanged.
Noninvestment-grade bonds tend to generate higher yields than investment-grade
bonds and have performed better than high-quality securities when interest rates
rise. The additional income they generate compensates for some of the decline in
principal value due to rising rates. At the same time, when economic growth
accelerates, prospects for credit upgrades improve, which also helps
performance.

     We were pleased with the Fund's surge in new assets during the reporting
period. The Fund's market value of investments at the end of this period was
$814 million, up from $677 million just six months earlier. The majority of new
assets have been invested in new high yield securities, allowing us to maintain
the Fund's cash position at just 4.2 percent. For additional Fund portfolio
highlights, please refer to page eight.

Q    How did the Fund perform during the reporting period?

A    The Fund posted a total return of 6.92 percent/1/ (Class A shares at net
asset value) for the six-month period ended February 28, 1998. By comparison,
the Credit Suisse First Boston High Yield Index returned 6.21 percent for the
same period. The First Boston High Yield Index is a broad-based index that
reflects the general performance of a wide range of selected bonds within the
public high yield debt market. It does not reflect any commissions or sales
charges 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.

Q    What is your outlook for the market over the coming months?

A    The market continues to be driven by a strong domestic economy, a benign
     rate of inflation, and tight labor markets. Nearly six months after the
Asian crisis, it's still unclear whether the weakness in Southeast Asia will
provoke a domestic economic slowdown that requires Federal Reserve Board
intervention. Either the Asian crisis will prove to be a small event in a self-
contained domestic economy, or its impact is large enough to slow domestic
activity and keep rates at a non-inflationary level. With the direction unclear,
we expect the spread between Treasuries and high yields to widen slightly, as
Treasury bonds are favored in light of market uncertainty. However, the
technical aspects that have steered the high yield market upward for the past
year remain strong, and high demand for attractive issues creates a tight 
supply-and-demand scenario. We will continue to monitor future market and
economic factors and position the Fund accordingly.

1. Significant Accounting Policies

Van Kampen American Capital High Income Corporate Bond Fund (the "Fund"), a
Delaware business trust, 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 maximum current income through
investment in high yielding, high risk fixed-income securities. The Fund
commenced investment operations on October 2, 1978. The Fund commenced
distribution of its Class B and Class C shares on July 2, 1992 and July 6, 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 Valuation-Fixed income investments and preferred stock are stated at
value using market quotations. Investments in securities listed on a securities
exchange are valued at the sale price as of the close of such securities
exchange. Unlisted securities and listed securities for which the last sales
price is not available are valued at the last reported bid price. For those
securities where quotations or prices are not available, valuations are
determined in accordance with 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.

  Fund investments include lower-rated debt securities which may be more
susceptible to adverse economic conditions than other 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. At the end of the period, debt securities rated below
investment grade and comparable unrated securities represented approximately 99%
of the investment portfolio. At February 28, 1998, approximately 15% of the
Fund's long-term investments were in non-U.S. issuers, of which the largest
geographic exposure was 5%.

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. At February 28, 1998, there were no
when issued or delayed delivery purchase commitments.

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

                         February 28, 1998 (Unaudited)
- --------------------------------------------------------------------------------
  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 "Adviser") or
its affiliates, the daily aggregate of which is invested in repurchase
agreements. Repurchase agreements are fully collateralized by the underlying
debt security. 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. Income and Expenses-Interest income is recorded on an accrual basis and
dividend income is recorded on the ex-dividend date. Original issue discounts on
debt securities purchased are amortized over the life of the respective
security. Premiums on debt securities are not amortized. Expenses of the Fund
are allocated on a pro rata basis to each class of shares, except for
distribution and service fees and transfer agency costs which are unique to each
class of shares.

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.

  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 such losses against any future realized capital
gains. At August 31, 1997, the Fund had an accumulated capital loss carryforward
for tax purposes of $224,476,411 which expires between August 31, 1998 and
August 31, 2004. Of this amount, $36,374,534 will expire in 1998. Net realized
gains or losses may differ for financial reporting and tax purposes primarily as
a result of the deferral of losses for tax purposes resulting from wash sales.

  At February 28, 1998, for federal income tax purposes, cost of long- and
short-term investments is $779,851,561, the aggregate gross unrealized
appreciation is $38,908,572 and the aggregate gross unrealized depreciation is
$4,482,670, resulting in net unrealized appreciation of $34,425,902.

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. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included in ordinary income for
tax purposes.

2. Investment Advisory Agreement and Other Transactions with Affiliates

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

Average Net Assets                                                  % Per Annum
- --------------------------------------------------------------------------------
First $150 million................................................   .625 of 1%
Next $150 million.................................................   .550 of 1%
Over $300 million.................................................   .500 of 1%

  For the six months ended February 28, 1998, the Fund recognized expenses of
approximately $19,400 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 six months ended February 28, 1998, the Fund recognized expenses of
approximately $62,900 representing Van Kampen American Capital Distributors,
Inc.'s or its affiliates' (collectively "VKAC") cost of providing accounting
services to the Fund.

  ACCESS Investor Services, Inc. ("ACCESS"), an affiliate of the Adviser, serves
as the shareholder servicing agent of the Fund. For the six months ended
February 28, 1998, the Fund recognized expenses of approximately $455,300,
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.

  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 Fund. The maximum annual benefit per
trustee under the plan is equal to $2,500.

                   Notes to Financial Statements (Continued)

                         February 28, 1998 (Unaudited)
================================================================================
  For the six months ended February 28, 1998, VKAC, as Distributor for the Fund,
received commissions on sales of the Fund's Class A shares of approximately
$114,500 and CDSC on redeemed shares of approximately $206,800. Sales charges do
not represent expenses of the Fund.

4. Investment Transactions

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $490,908,433 and $363,895,635,
respectively.

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 or generate potential gain. 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. Upon
disposition, a realized gain or loss is recognized accordingly, except when
taking delivery of a security underlying a futures contract. In this instance,
the recognition of gain or loss is postponed until the disposal of the security
underlying the futures contract.

  During the period, the Fund invested in futures 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 Notes. These contracts are
generally used to manage the portfolio's effective maturity and duration.

  Upon entering into futures 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 six months ended February 28, 1998,
were as follows:


                                                                      Contracts

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% of Class A average net assets and
1.00% each for Class B and Class C average net assets are accrued daily.
Included in these fees for the six months ended February 28, 1998, are payments
retained by VKAC of approximately $903,800.
