PRESIDENT'S LETTER

DEAR SHAREHOLDER,
--------------------------------------------------------------------------------

For many years, we have encouraged investors to consider whether they could
tolerate more risk in their long-term investments by participating in the stock
market, which has historically provided higher long-term returns than any other
asset class. Today, however, we have a very different concern: some investors
may have assumed too much risk by concentrating their investments in just a
handful of stocks or sectors or by "chasing performance."

    Several months ago, Alan Greenspan, the Chairman of the Federal Reserve
Board, stated his view that the spectacular returns some sectors of the market
were then experiencing may have been partly responsible for pushing our economy
to growth rates that could lead to higher inflation. Today it is clear that the
dramatic rise in the prices of a narrow segment of the market created enormous
wealth for some investors. The result of this newfound wealth has been a
substantial increase in spending that the Federal Reserve Board believes could
threaten the healthy growth of our economy.

    That's why the Fed has been raising interest rates steadily and decisively
over the past year. By making borrowing more expensive, the Fed has been
attempting to slow economic growth. It is a precarious balancing act: too much
tightening creates the risk of recession, while too little opens the door to
inflation.

    The implications of the Fed's resolve are clear: investors must continue to
be prepared for near-term market volatility. In the bond market, higher interest
rates usually lead to lower bond prices. In the stock market, slower economic
growth often reduces corporate earnings and puts downward pressure on stock
prices. Highly valued stocks can be particularly vulnerable to a correction. The
Securities and Exchange Commission Chairman, Arthur Levitt, has been cautioning
investors against the expectation that the types of returns seen in the recent
bull market will last forever.

PRESIDENT'S LETTER
--------------------------------------------------------------------------------

    Because of the prospect of continued market volatility, we encourage you to
consider diversifying your investments. Indeed, diversification may help you
mitigate the effects of sharp declines in any one area. It may also help you
better position your portfolio to seek greater returns over the long run.

    While some "new economy" stocks have risen over the last year, many
so-called "old economy" stocks are selling at low prices. In the bond market,
higher interest rates over the short term may reduce inflation concerns, which
should be beneficial over the long term. By buying out-of-favor investments, you
may be able to profit when and if they return to favor.

    What specific investments should you consider today so that you are prepared
for tomorrow? The answer depends on your individual investing goals, risk
tolerance and financial circumstances. We urge you to talk with your financial
advisor about ways to diversify your portfolio. This may include con-sidering
global diversification as part of your strategy. While investing abroad has
special risks, such as the effects of foreign currency fluctuations, it also
offers opportunities to participate in global economic growth and to hedge
against the volatility in U.S. markets.

    We thank you for your continued confidence in OppenheimerFunds, The Right
Way to Invest.

Sincerely,

/s/ BRIDGET A. MACASKILL

AN INTERVIEW WITH YOUR FUND'S MANAGERS
--------------------------------------------------------------------------------

HOW DID OPPENHEIMER WORLD BOND FUND PERFORM OVER THE SIX-MONTH PERIOD THAT ENDED
APRIL 30, 2000?

A. We are generally pleased with the Fund's returns in what has been a mixed bag
for global bond markets. During the six-month reporting period, stronger than
expected economic growth throughout the world fueled concerns that inflationary
pressures might reemerge. As a result, tighter monetary policy worldwide pushed
many bond yields higher. Because bond yields and prices generally move in
opposite directions, higher interest rates eroded the value of many fixed income
securities. However, by focusing on what we believed were the highest yielding,
positive performing sectors of the global bond market, we were able to provide a
competitive yield in a declining market.(1)

WHAT WAS THE ECONOMIC ENVIRONMENT LIKE DURING THE PERIOD?

When the reporting period began on November 1, 1999, it had become apparent that
many of the world's economies were growing robustly. The emerging markets of
Asia, Eastern Europe and, to a lesser extent, Latin America, had made a
remarkable recovery from the 1998 global financial crisis. Many developed
markets stabilized, with most European economies experiencing moderate growth,
while Japan's economy showed only budding signs of recovery after nearly a
decade of recession.

1. Investing in foreign bonds, especially in emerging markets, entails higher
expenses and risks, such as foreign currency fluctuations. Investing in high
yield junk bonds carries greater risk of volatility and default. Please see the
prospectus for more information on the risks of investing in the Fund.

AN INTERVIEW WITH YOUR FUND'S MANAGERS
--------------------------------------------------------------------------------

"Although the past six months have been challenging for many bonds, our focus on
high-yielding securities helped enhance the Fund's performance."

    In the United States, the economy was robust, but a combination of tight
labor markets, rising commodity prices and high levels of consumer borrowing
raised fears of higher inflation down the road. Additionally, Federal Reserve
Chairman Alan Greenspan voiced concern over the "wealth effect," as stock
valuations continued to rise and income from investments in the stock market
fueled vigorous household spending. Questioning the economy's ability to sustain
its rapid growth, the Federal Reserve Board continued to raise short-term
interest rates, with additional hikes in November, February and March.

    While many bond investors were prepared for these moves, they were less so
for the U.S. Treasury Department's buyback program, announced in late January of
this year. This repurchase of a larger-than-expected portion of outstanding
Treasury debt created an acute imbalance between supply and demand for U. S.
Treasury securities, particularly on the long end of the maturity spectrum. With
long bonds already in short supply, increased demand drove prices up
dramatically. However, as yields on longer-term bonds dipped below yields on
shorter issues, inverting the yield curve, longer issues still in circulation
became even more valuable.

HOW DID YOU MANAGE THE FUND IN THIS ENVIRONMENT?

We have focused on seeking to maximize income in a rising interest rate
environment. We generally avoided lower yielding securities from countries with
relatively low rates of economic growth. Instead, we emphasized higher yielding
bonds from countries with strong economies. Focusing on credit-sensitive rather
than interest rate-sensitive bonds helped provide above-average income streams,
which helped offset the effects of declining bond prices.

WHERE HAVE YOU FOUND THE MOST ATTRACTIVE OPPORTUNITIES FOR INVESTMENT DURING THE
PAST SIX MONTHS?

Of the various international markets, emerging-market bonds contributed the most
to performance. Consistent with our value orientation, we purchased many of our
current holdings in 1998, when they fell out of favor due to the global
financial crisis. As market conditions and investor interest have improved, we
have taken a more aggressive stance.

    On the other hand, our holdings of foreign bonds from many developed markets
were negatively influenced by the strength of the U.S. dollar relative to most
European currencies, including the euro. Many European economies were growing at
slower rates than the U.S. economy, making U.S. investments relatively more
attractive to domestic and foreign investors alike. However, we believe there
are investment opportunities in the United Kingdom and many Scandinavian
countries.

    In the United States, we allocated part of the portfolio to "spread
products" such as mortgage-backed securities. These types of securities
typically provide extra yield above Treasuries, and generally perform better in
a rising-rate environment. Throughout the last six months, we sought to take
advantage of weakness in the mortgage-backed securities sector to add what we
believed were a number of compelling high-quality holdings.

yields.

WHAT IS YOUR OUTLOOK OVER THE FORESEEABLE FUTURE?

We remain optimistic. We expect the Federal Reserve and other central banks to
employ tighter monetary policy until they see evidence that inflation will
remain under control. In our view, U.S. investors could expect to see several
more interest-rate increases, which we believe have already been priced into
long-term bond yields. Because of its size and scope, the U.S. economy
influences many worldwide markets. However, we believe that any further price
erosion among longer-term bonds should be limited.

    We will seek to continue to manage the Fund in a way that takes advantage of
the changing relationships among the various sectors of the global bond market.
In fact, adhering to our long-term investment discipline is just one of the many
reasons why Oppenheimer World Bond Fund is an important part of The Right Way to
Invest.

(1.) Interest-Only Strips represent the right to receive the monthly interest
payments on an underlying pool of mortgage loans. These securities typically
decline in price as interest rates decline. Most other fixed income securities
increase in price when interest rates decline. The principal amount of the
underlying pool represents the notional amount on which current interest is
calculated. The price of these securities is typically more sensitive to changes
in prepayment rates than traditional mortgage-backed securities (for example,
GNMA pass-throughs). Interest rates disclosed represent current yields based
upon the current cost basis and estimated timing and amount of future cash
flows.
(2.) Option footnote: Note: Insert worksheet option.
(3.) A sufficient amount of securities has been designated to cover outstanding
foreign currency contracts. See Note 5 of Notes to Financial Statements.
(4.) Identifies issues considered to be illiquid--See Note 8 of Notes to
Financial Statements.
(5.) Represents the current interest rate for a variable or increasing rate
security.

NOTES TO FINANCIAL STATEMENTS Unaudited

===============================================================================
1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer World Bond Fund (the Fund) is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
The Fund's investment objective is to seek total return. The Fund's investment
advisor is OppenheimerFunds, Inc. (the Manager).

     The Fund offers Class A, Class B and Class C shares. Class A shares are
sold at their offering price, which is normally net asset value plus an initial
sales charge. Class B and Class C shares are sold without an initial sales
charge but may be subject to a contingent deferred sales charge (CDSC). All
classes of shares have identical rights to earnings, assets and voting
privileges, except that each class has its own expenses directly attributable to
that class and exclusive voting rights with respect to matters affecting that
class. Classes A, B and C shares have separate distribution and/or service
plans. Class B shares will automatically convert to Class A shares six years
after the date of purchase. The following is a summary of significant accounting
policies consistently followed by the Fund.
--------------------------------------------------------------------------------
SECURITIES VALUATION. Securities for which quotations are readily available are
valued at the last sale price, or if in the absence of a sale, at the last sale
price on the prior trading day if it is within the spread of the closing bid and
asked prices, and if not, at the closing bid price. Securities (including
restricted securities) for which quotations are not readily available are valued
primarily using dealer-supplied valuations, a portfolio pricing service
authorized by the Board of Trustees, or at their fair value. Fair value is
determined in good faith under consistently applied procedures under the
supervision of the Board of Trustees. Foreign currency contracts are valued
based on the closing prices of the forward currency contract rates in the London
foreign exchange markets on a daily basis as provided by a reliable bank, dealer
or pricing service. Short-term "money market type" debt securities with
remaining maturities of sixty days or less are valued at cost (or last
determined market value) and adjusted for amortization or accretion to maturity
of any premium or discount.
--------------------------------------------------------------------------------
STRUCTURED NOTES. The Fund invests in foreign currency-linked structured notes
whose market value and redemption price are linked to foreign currency exchange
rates. The structured notes may be leveraged, which increases the notes'
volatility relative to the face of the security. Fluctuations in value of these
securities are recorded as unrealized gains and losses in the accompanying
financial statements. As of April 30, 2000, the market value of these securities
comprised 3.21% of the Fund's net assets and resulted in realized and unrealized
losses of $322,391. The Fund also hedges a portion of the foreign currency
exposure generated by these securities, as discussed in Note 5.

===============================================================================
1. SIGNIFICANT ACCOUNTING POLICIES Continued
SECURITIES PURCHASED ON A WHEN-ISSUED BASIS. Delivery and payment for securities
that have been purchased by the Fund on a forward commitment or when-issued
basis can take place a month or more after the transaction date. Normally the
settlement date occurs within six months after the transaction date; however,
the Fund may, from time to time, purchase securities whose settlement date
extends beyond six months and possibly as long as two years or more beyond trade
date. During this period, such securities do not earn interest, are subject to
market fluctuation and may increase or decrease in value prior to their
delivery. The Fund maintains segregated assets with a market value equal to or
greater than the amount of its purchase commitments. The purchase of securities
on a when-issued or forward commitment basis may increase the volatility of the
Fund's net asset value to the extent the Fund makes such purchases while
remaining substantially fully invested. As of April 30, 2000, the Fund had
entered into net outstanding when-issued or forward commitments of $161,311.

     In connection with its ability to purchase securities on a when-issued or
forward commitment basis, the Fund may enter into mortgage dollar-rolls in which
the Fund sells securities for delivery in the current month and simultaneously
contracts with the same counterparty to repurchase similar (same type, coupon
and maturity) but not identical securities on a specified future date. The Fund
records each dollar-roll as a sale and a new purchase transaction.
-------------------------------------------------------------------------------
SECURITY CREDIT RISK. The Fund invests in high yield securities, which may be
subject to a greater degree of credit risk, greater market fluctuations and risk
of loss of income and principal, and may be more sensitive to economic
conditions than lower yielding, higher rated fixed income securities. The Fund
may acquire securities in default, and is not obligated to dispose of securities
whose issuers subsequently default. As of April 30, 2000, securities with an
aggregate market value of $613,430, representing 1.49% of the Fund's net assets,
were in default.
-------------------------------------------------------------------------------
FOREIGN CURRENCY TRANSLATION. The accounting records of the Fund are maintained
in U.S. dollars. Prices of securities denominated in foreign currencies are
translated into U.S. dollars at the closing rates of exchange. Amounts related
to the purchase and sale of foreign securities and investment income are
translated at the rates of exchange prevailing on the respective dates of such
transactions.
    The effect of changes in foreign currency exchange rates on investments is
separately identified from the fluctuations arising from changes in market
values of securities held and reported with all other foreign currency gains and
losses in the Fund's Statement of Operations.

                         24 OPPENHEIMER WORLD BOND FUND


<PAGE>   27

-------------------------------------------------------------------------------
REPURCHASE AGREEMENTS. The Fund requires the custodian to take possession, to
have legally segregated in the Federal Reserve Book Entry System or to have
segregated within the custodian's vault, all securities held as collateral for
repurchase agreements. The market value of the underlying securities is required
to be at least 102% of the resale price at the time of purchase. If the seller
of the agreement defaults and the value of the collateral declines, or if the
seller enters an insolvency proceeding, realization of the value of the
collateral by the Fund may be delayed or limited.
-------------------------------------------------------------------------------
ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated daily to
each class of shares based upon the relative proportion of net assets
represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.
-------------------------------------------------------------------------------
FEDERAL TAXES. The Fund intends to continue to comply with provisions of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income, including any net realized gain on
investments not offset by loss carryovers, to shareholders. Therefore, no
federal income or excise tax provision is required. As of October 31, 1999, the
Fund had available for federal income tax purposes an unused capital loss
carryover of approximately $8,678,000, which expires between 2002 and 2007.
    The Manager believes that for the Fund's fiscal year ending October 31,
2000, a tax return of capital is likely to occur. The dollar and per share
amounts for the fiscal year are not estimable as of April 30, 2000.
-------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan for the
Fund's independent Board of Trustees. Benefits are based on years of service and
fees paid to each trustee during the years of service. During the six months
ended April 30, 2000, a credit of $6,368 was made for the Fund's projected
benefit obligations and payments of $2,592 were made to retired trustees,
resulting in an accumulated liability of $78,308 as of April 30, 2000.
    The Board of Trustees has adopted a deferred compensation plan for
independent trustees that enables trustees to elect to defer receipt of all or a
portion of annual compensation they are entitled to receive from the Fund. Under
the plan, the compensation deferred is periodically adjusted as though an
equivalent amount had been invested for the Board of Trustees in shares of one
or more Oppenheimer funds selected by the trustee. The amount paid to the Board
of Trustees under the plan will be determined based upon the performance of the
selected funds. Deferral of trustees' fees under the plan will not affect the
net assets of the Fund, and will not materially affect the Fund's assets,
liabilities or net investment income per share.
-------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date.

NOTES TO FINANCIAL STATEMENTS Unaudited/Continued

===============================================================================
1. SIGNIFICANT ACCOUNTING POLICIES Continued
CLASSIFICATION OF DISTRIBUTIONS TO SHAREHOLDERS. Net investment income (loss)
and net realized gain (loss) may differ for financial statement and tax purposes
primarily because of the recognition of certain foreign currency gains (losses)
as ordinary income (loss) for tax purposes. The character of distributions made
during the year from net investment income or net realized gains may differ from
its ultimate characterization for federal income tax purposes. Also, due to
timing of dividend distributions, the fiscal year in which amounts are
distributed may differ from the fiscal year in which the income or realized gain
was recorded by the Fund.
-------------------------------------------------------------------------------
EXPENSE OFFSET ARRANGEMENTS. Expenses paid indirectly represent a reduction of
custodian fees for earnings on cash balances maintained by the Fund.
-------------------------------------------------------------------------------
OTHER. Investment transactions are accounted for as of trade date and dividend
income is recorded on the ex-dividend date. Discount on securities purchased is
amortized over the life of the respective securities, in accordance with federal
income tax requirements. Realized gains and losses on investments and options
written and unrealized appreciation and depreciation are determined on an
identified cost basis, which is the same basis used for federal income tax
purposes. Dividends-in-kind are recognized as income on the ex-dividend date, at
the current market value of the underlying security. Interest on payment-in-kind
debt instruments is accrued as income at the coupon rate and a market adjustment
is made periodically.

     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 income and expenses during the reporting
period. Actual results could differ from those estimates.

The Fund has adopted a Service Plan for Class A shares and Distribution and

Company Act. Under those plans the Fund pays the Distributor for all or a
portion of its costs incurred in connection with the distribution and/or
servicing of the shares of the particular class.

-------------------------------------------------------------------------------
CLASS A SERVICE PLAN FEES. Under the Class A service plan, the Distributor
currently uses the fees it receives from the Fund to pay brokers, dealers and
other financial institutions. The Class A service plan permits reimbursements to
the Distributor at a rate of up to 0.25% of average annual net assets of Class A
shares purchased. The Distributor makes payments to plan recipients quarterly at
an annual rate not to exceed 0.25% of the average annual net assets consisting
of Class A shares of the Fund. For the six months ended April 30, 2000, payments
under the Class A plan totaled $34,733, all of which was paid by the Distributor
to recipients. Any unreimbursed expenses the Distributor incurs with respect to
Class A shares in any fiscal year cannot be recovered in subsequent years.
-------------------------------------------------------------------------------
CLASS B AND CLASS C DISTRIBUTION AND SERVICE PLAN FEES. Under each plan, service
fees and distribution fees are computed on the average of the net asset value of
shares in the respective class, determined as of the close of each regular
business day during the period. The Class B and Class C plans provide for the
Distributor to be compensated at a flat rate, whether the Distributor's
distribution expenses are more or less than the amounts paid by the Fund under
the plan during the period for which the fee is paid.
    The Distributor retains the asset-based sales charge on Class B shares. The
Distributor retains the asset-based sales charge on Class C shares during the
first year the shares are outstanding. The asset-based sales charges on Class B
and Class C shares allow investors to buy shares without a front-end sales
charge while allowing the Distributor to compensate dealers that sell those
shares.
    The Distributor's actual expenses in selling Class B and Class C shares may
be more than the payments it receives from the contingent deferred sales charges
collected on redeemed shares and asset-based sales charges from the Fund under
the plans. If any plan is terminated by the Fund, the Board of Trustees may
allow the Fund to continue payments of the asset-based sales charge to the
Distributor for distributing shares before the plan was terminated. The plans
allow for the carryforward of distribution expenses, to be recovered from
asset-based sales charges in subsequent fiscal periods.

Distribution fees paid to the Distributor for the six months ended April 30,
2000, were as follows:

5. FOREIGN CURRENCY CONTRACTS

A foreign currency contract is a commitment to purchase or sell a foreign
currency at a future date, at a negotiated rate. The Fund may enter into foreign
currency contracts for operational purposes and to seek to protect against
adverse exchange rate fluctuations. Risks to the Fund include the potential
inability of the counterparty to meet the terms of the contract.
    The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates as provided by
a reliable bank, dealer or pricing service. Unrealized appreciation and
depreciation on foreign currency contracts are reported in the Statement of
Assets and Liabilities.
    The Fund may realize a gain or loss upon the closing or settlement of the
foreign currency transactions. Realized gains and losses are reported with all
other foreign currency gains and losses in the Statement of Operations.
    Securities denominated in foreign currency to cover net exposure on
outstanding foreign currency contracts are noted in the Statement of Investments
where applicable.

As of April 30, 2000, the Fund had outstanding foreign currency contracts as
follows:

6. FUTURES CONTRACTS

The Fund may buy and sell futures contracts in order to gain exposure to or to
seek to protect against changes in interest rates. The Fund may also buy or
write put or call options on these futures contracts.
    The Fund generally sells futures contracts to hedge against increases in
interest rates and the resulting negative effect on the value of fixed rate
portfolio securities. The Fund may also purchase futures contracts to gain
exposure to changes in interest rates as it may be more efficient or cost
effective than actually buying fixed income securities.
    Upon entering into a futures contract, the Fund is required to deposit
either cash or securities (initial margin) in an amount equal to a certain
percentage of the contract value. Subsequent payments (variation margin) are
made or received by the Fund each day. The variation margin payments are equal
to the daily changes in the contract value and are recorded as unrealized gains
and losses. The Fund may recognize a realized gain or loss when the contract is
closed or expires.
    Securities held in collateralized accounts to cover initial margin
requirements on open futures contracts are noted in the Statement of
Investments. The Statement of Assets and Liabilities reflects a receivable
and/or payable for the daily mark to market for variation margin.
    Risks of entering into futures contracts (and related options) include the
possibility that there may be an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.

As of April 30, 2000, the Fund had outstanding futures contracts as follows:

7. OPTION ACTIVITY

The Fund may buy and sell put and call options, or write put and covered call
options on portfolio securities in order to produce incremental earnings or
protect against changes in the value of portfolio securities.
    The Fund generally purchases put options or writes covered call options to
hedge against adverse movements in the value of portfolio holdings. When an
option is written, the Fund receives a premium and becomes obligated to sell or
purchase the underlying security at a fixed price, upon exercise of the option.
    Options are valued daily based upon the last sale price on the principal
exchange on which the option is traded and unrealized appreciation or
depreciation is recorded. The Fund will realize a gain or loss upon the
expiration or closing of the option transaction. When an option is exercised,
the proceeds on sales for a written call option, the purchase cost for a written
put option, or the cost of the security for a purchased put or call option is
adjusted by the amount of premium received or paid.
    Securities designated to cover outstanding call options are noted in the
Statement of Investments where applicable. Shares subject to call, expiration
date, exercise price, premium received and market value are detailed in a note
to the Statement of Investments. Options written are reported as a liability in
the Statement of Assets and Liabilities. Gains and losses are reported in the
Statement of Operations.
    The risk in writing a call option is that the Fund gives up the opportunity
for profit if the market price of the security increases and the option is
exercised. The risk in writing a put option is that the Fund may incur a loss if
the market price of the security decreases and the option is exercised. The risk
in buying an option is that the Fund pays a premium whether or not the option is
exercised. The Fund also has the additional risk of not being able to enter into
a closing transaction if a liquid secondary market does not exist.

Written option activity for the six months ended April 30, 2000 was as follows:

8. ILLIQUID SECURITIES

As of April 30, 2000, investments in securities included issues that are
illiquid. A security may be considered illiquid if it lacks a readily available
market or if its valuation has not changed for a certain period of time. The
Fund intends to invest no more than 10% of its net assets (determined at the
time of purchase and reviewed periodically) in illiquid securities. The
aggregate value of illiquid securities subject to this limitation as of April
30, 2000 was $2,374,720, which represents 5.77% of the Fund's net assets.
-------------------------------------------------------------------------------
9. BANK BORROWINGS

The Fund may borrow from a bank for temporary or emergency purposes including,
without limitation, funding of shareholder redemptions provided asset coverage
for borrowings exceeds 300%. The Fund has entered into an agreement which
enables it to participate with other Oppenheimer funds in an unsecured line of
credit with a bank, which permits borrowings up to $400 million, collectively.
Interest is charged to each fund, based on its borrowings, at a rate equal to
the Federal Funds Rate plus 0.45%. Borrowings are payable 30 days after such
loan is executed. The Fund also pays a commitment fee equal to its pro rata
share of the average unutilized amount of the credit facility at a rate of 0.08%
per annum.
     The Fund had no borrowings outstanding during the six months ended April
 30, 2000.
