o Both domestic high yield bonds and emerging market debt declined in August
when investors expressed their preference for only the highest-quality
securities amid global economic and political uncertainty.

o The Fund's holdings of U.S. Treasury securities served as an anchor for the
portfolio during a time of extreme turbulence in other market sectors.(1)

o Currently, many high-yield bonds and selected foreign bonds appear to be
undervalued, giving rise to potential opportunities to buy these securities at
attractive prices.

The performance of the financial markets over the past several months could be
viewed as "A Tale of Two Markets." Until mid-July, the excitement surrounding
the stock market's continued ascent to new record highs overshadowed the
favorable economic environment that existed for bonds: low inflation and
declining interest rates. However, since late summer, amid heightened global
concern, stocks declined sharply. Yet, despite continued economic concerns
worldwide, the bond market appeared ready to benefit.

      Why have the stock and bond markets responded differently? The financial
crises in Asia and Russia have weakened the earnings of some large U.S.
corporations and have contributed to a slowdown in U.S. economic growth.
Although this slowing economic growth has negatively impacted stocks, it created
a positive environment for bonds. That's because slowing economic growth
generally means fewer inflationary pressures and, as we've recently seen,
interest rates also tend to decline.

      What should you do during this period of relative uncertainty? If you have
well-defined, long-term financial goals and an investment strategy designed to
achieve them, we encourage you to stay the course. However, if you feel your
financial plan is out-of-date or incomplete, now is the time to make
improvements. The best way to cope with short-term volatility is to adhere to a
long-term plan that contains proven strategies, such as diversification among
various financial markets, geographic regions, investment styles and individual
securities. A long-term plan will give you the focus and perspective you need to
put short-term volatility in its proper context.

      As longstanding advocates of financial planning, we have been encouraged
by our shareholders' rational responses to the latest market events. Many of you
tell us that you have a long-term strategy in place, which includes diversifying
your investment portfolio among a number of different asset classes in
accordance with your tolerance for risk. At OppenheimerFunds, our portfolio
management teams include seasoned professionals who have encountered extreme
market volatility in the past, giving them the perspective required to address
risks and take advantage of opportunities in turbulent markets. In our view,
having a well-defined set of financial goals, a disciplined long-term strategy
and the help of experienced investment professionals are all fundamental parts
of The Right Way to Invest.

Sincerely,

/s/ James C. Swain           /s/ Bridget A. Macaskill

An interview with your Fund's managers
- --------------------------------------------------------------------------------

"We're finding some very attractive values in bonds that, in our opinion, were
unfairly punished in the recent declines."

Did extreme volatility in the financial markets affect the Fund's performance?

The month of August was one of the most difficult in memory both for the Fund
and the markets in which it invests. Of the three market sectors in which the
Fund invests--U.S. government, foreign and high yield bonds--two declined
sharply in August, causing the Fund's net asset value to fall. A severe and
simultaneous decline in two different market sectors is a highly unusual event.
Historically, declines in any one sector tend to be offset by good performance
in the two other sectors.

Which sectors of the bond markets declined, and why?

The emerging-markets segment of the foreign bond sector and the domestic high
yield bond market both experienced difficulties.

      Bond prices in the emerging markets of Southeast Asia began to decline in
October 1997, when currency devaluations forced some overextended Asian
companies to default on their debt. Risk-averse investors pulled their capital
out of Southeast Asia and other emerging markets, causing prices of both bonds
and stocks to plummet. More recently in 1998, Japan's failure to enact the
reforms necessary to fix their troubled economy put further pressure on the
emerging markets in Asia. Meanwhile, Russia was forced to devalue its currency
in mid-August because of the apparent ineffectiveness of a plan by the
International Monetary Fund to support Russia's economy. Finally, plunging oil
prices led to fears of currency devaluation in certain Latin American countries.

Closer to home, the domestic high yield bond market responded to many of the
same influences that drove the U.S. stock market lower during the third quarter
of 1998. In the wake of the Asian crisis, some U.S. companies revealed that
their earnings would not meet analysts expectations. In response, investors
attempted to sell all but the most creditworthy securities, including high yield
bonds. In our opinion, they did so without regard to the degree of fundamental
soundness of the individual issuers or business conditions.

How did the U.S. government bond market perform in this environment?

The "flight to quality" that negatively influenced stocks and corporate bonds in
the United States affected even relatively high-quality fixed income investments
such as U.S. agency securities. Despite guarantees from government agencies such
as the Government National Mortgage Association (Ginnie Mae), risk-averse
investors sold these triple-A rated securities in favor of U.S. Treasury
securities, which are considered the most secure investments in the world. In
fact, yields on 30-year Treasury bonds dropped below 5 1/2 percent in August for
the first time since the 1960s.

The Fund benefited from the rally of U.S. Treasury securities because nearly 18%
of the Fund's assets were committed to this market sector as of July 31, before
the foreign and high yield markets' sharp declines in August. In effect, our
holdings of U.S. Treasury securities served as an anchor for the portfolio.

Do you intend to change the way the Fund is managed as a result of the August
declines? 

Absolutely not. Our focus continues to be on long-term performance, not
short-term volatility. We will continue to diversify the Fund's assets in
varying degrees among U.S. government, foreign and domestic high yield bonds. In
our view, August 1998 was an anomaly that is not likely to reoccur anytime soon.

      In this uncertain environment, however, effective risk management has
become more important than ever. What's required in nervous markets like this
one is a long-term perspective combined with some tolerance for short-term
volatility. With patience and discipline, we believe that today's short-term
challenges should give way to longer term opportunities.

Is there a silver lining to the cloud that appears to have settled over the
emerging markets and high yield bond markets? 

In our view, most sectors of the global bond markets are extraordinarily
inexpensive compared to their historical relationships with U.S. Treasury
securities. As a result, we're finding some very attractive values in bonds
that, in our opinion, were unfairly punished in the recent declines. We're
finding particularly good values in North America, South America and Europe.

      We are also finding similar values in high yield bonds. Many corporate
bond prices have declined to levels that appear to reflect a worst-case
scenario, such as a recession in the United States. We believe that a recession
is unlikely in today's low-inflation environment. If and when it becomes clear
to the broader investment community that a recession is unlikely, we expect
corporate bond prices to rise to more normal valuations.

What is your outlook for the future?

News from overseas markets may continue to be unsettling until evidence appears
that Southeast Asia, Japan, Russia and other troubled economies are on the mend.
On the other hand, we believe that Latin American bonds are generally
undervalued, and we are watchful for opportunities to obtain creditworthy bonds
at attractive prices. In the United States, we remain encouraged by the
fundamentals of a resilient economy, particularly the absence of inflationary
pressures.

2. Standardized yield is based on net investment income for the 30-day period
ended 9/30/98. Falling share prices will tend to artificially raise yields.

We expect our core holdings of U.S. Treasury securities to provide a stable
foundation from which we can begin investing opportunistically in carefully
selected, higher yielding domestic and foreign fixed income securities. In our
view, this type of multi-sector diversification continues to be an important
part of The Right Way to Invest in the fixed-income markets.

Fund performance
- --------------------------------------------------------------------------------

How Has the Fund Performed? Below is a discussion by the Manager of the Fund's
performance during its fiscal year ended September 30, 1998, followed by a
graphical comparison of the Fund's performance to two appropriate broad-based
market indices.

      o Management's Discussion of Performance. During the fiscal year ended
September 30, 1998, Oppenheimer Strategic Income Fund's performance was
negatively affected by a number of factors, including weakness in the high yield
and emerging-markets bond markets during the third quarter of 1998. The negative
effects of the overall markets' declines were only partially offset by strength
in the Fund's U.S. government securities portfolio. As a result, the Fund's
performance suffered over the period. The Fund's portfolio holdings, allocations
and strategies are subject to change.

      o Comparing the Fund's Performance to the Market. The graphs that follow
show the performance of a hypothetical $10,000 investment in each class of
shares of the Fund held until September 30, 1998. In the case of Class A shares,
performance is measured over a one- and five-year period and from the inception
of the class on October 16, 1989. In the case of Class B shares, performance is
measured over a one- and five-year period and from the inception of the class on
November 30, 1992. In the case of Class C shares, performance is measured over a
one-year period and from the inception of the class on May 26, 1995. In the case
of Class Y shares, performance is measured since the inception of the class on
January 26, 1998. The graphs assume that all dividends and capital gains
distributions were reinvested in additional shares. The Fund's performance
reflects the deduction of the 4.75% maximum initial sales charge on Class A
shares, the 5% (1-year), 2% (5-year) and 1% (since inception) applicable
contingent deferred sales charge for Class B, and the 1% (1-year) contingent
deferred sales charge for Class C shares.

      The performance of each class of the Fund's shares is compared to two
indices because the Fund invests in a variety of debt securities in domestic and
foreign markets. The Fund's performance is compared to the performance of the
Lehman Brothers Aggregate Bond Index and the Salomon Brothers World Government
Bond Index. The Lehman Brothers Aggregate Bond Index is a broad-based, unmanaged
index of U.S. corporate bond issues, U.S. Government securities and
mortgage-backed securities widely regarded as a measure of the performance of
the domestic debt securities market. The Salomon Brothers World Government Bond
Index is an unmanaged index of fixed rate bonds having a maturity of one year or
more, widely regarded as a benchmark of fixed income performance on a worldwide
basis.

      Index performance reflects the reinvestment of income but does not
consider the effect of capital gains or transaction costs, and none of the data
in the graphs that follow shows the effect of taxes. The Fund's performance
reflects the effects of Fund business and operating expenses. While index
comparisons may be useful to provide a benchmark for the Fund's performance, it
must be noted that the Fund's investments are not limited to the securities in
the indices and include below-investment-grade obligations.

2. Identifies issues considered to be illiquid or restricted -- See Note 8 of
Notes to Financial Statements.

3. 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.

4. Principal-Only Strips represent the right to receive the monthly principal
payments on an underlying pool of mortgage loans. The value of these securities
generally increases as interest rates decline and prepayment rates rise. The
price of these securities is typically more volatile than that of coupon-bearing
bonds of the same maturity. Interest rates disclosed represent current yields
based upon the current cost basis and estimated timing of future cash flows.

5. Represents the current interest rate for a variable rate security.

6. Represents securities sold under Rule 144A, which are exempt from
registration under the Securities Act of 1933, as amended. These securities have
been determined to be liquid under guidelines established by the Board of
Trustees. These securities amount to $433,777,611 or 5.02% of the Fund's net
assets as of September 30, 1998.

7. A sufficient amount of securities has been designated to cover outstanding
forward foreign currency exchange contracts. See Note 5 of Notes to Financial
Statements.

8. Securities with an aggregate market value of $46,936,687 are held in
collateralized accounts to cover initial margin requirements on open futures
sales contracts. See Note 6 of Notes to Financial Statements.

9. For zero coupon bonds, the interest rate shown is the effective yield on the
date of purchase.

================================================================================
1. Significant Accounting Policies

Oppenheimer Strategic Income Fund (the Fund) is a separate series of Oppenheimer
Strategic Funds Trust, a diversified, open-end management investment company
registered under the Investment Company Act of 1940, as amended. The Fund's
investment objective is to seek a high level of current income by investing
mainly in debt securities. The Fund's investment advisor is OppenheimerFunds,
Inc. (the Manager). The Fund offers Class A, Class B, Class C and Class Y
shares. Class A shares are sold with a front-end sales charge. Class B and Class
C shares may be subject to a contingent deferred sales charge. 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 single class.
Classes A, B and C have separate distribution and/or service plans. No such plan
has been adopted for Class Y shares. 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.

- --------------------------------------------------------------------------------
Investment Valuation. Portfolio securities are valued at the close of the New
York Stock Exchange on each trading day. Listed and unlisted securities for
which such information is regularly reported are valued at the last sale price
of the day or, in the absence of sales, at values based on the closing bid or
the last sale price on the prior trading day. Long-term and short-term
"non-money market" debt securities are valued by a portfolio pricing service
approved by the Board of Trustees. Such securities which cannot be valued by the
approved portfolio pricing service are valued using dealer-supplied valuations
provided the Manager is satisfied that the firm rendering the quotes is reliable
and that the quotes reflect current market value, or are valued under
consistently applied procedures established by the Board of Trustees to
determine fair value in good faith. Short-term "money market type" debt
securities having a remaining maturity of 60 days or less are valued at cost (or
last determined market value) adjusted for amortization to maturity of any
premium or discount. Forward foreign currency exchange 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 or
dealer. Options are valued based upon the last sale price on the principal
exchange on which the option is traded or, in the absence of any transactions
that day, the value is based upon the last sale price on the prior trading date
if it is within the spread between the closing bid and asked prices. If the last
sale price is outside the spread, the closing bid is used.

================================================================================
1. Significant Accounting Policies (continued)

Structured Notes. The Fund invests in commodity and foreign currency-linked
structured notes whereby the market value and redemption price are linked to
commodity indices and foreign currency exchange rates. The Fund also invests in
index-linked notes whereby the principal and/or interest payment depend on one
or more market indices. The structured notes may be leveraged, which increases
the notes' volatility relative to the face value of the security. Fluctuations
in values of the securities are recorded as unrealized gains and losses in the
accompanying financial statements. During the year ended September 30, 1998, the
market value of these securities comprised an average of 7% of the Fund's net
assets, and resulted in realized and unrealized losses of $178,967,859.

- --------------------------------------------------------------------------------
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. 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, in a segregated account with its custodian, assets with a market
value equal to 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 September 30,
1998, the Fund had entered into outstanding when-issued or forward commitments
of $189,524,234.

            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 September 30, 1998, securities with an
aggregate market value of $12,720,858, representing 0.15% 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.

- --------------------------------------------------------------------------------
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 September 30, 1998,
the Fund had available for federal income tax purposes an unused capital loss
carryover of approximately $116,832,000, expiring in 2004.

- --------------------------------------------------------------------------------
Distributions to Shareholders. The Fund intends to declare dividends separately
for Class A, Class B, Class C and Class Y shares from net investment income each
day the New York Stock Exchange is open for business and pay such dividends
monthly. Distributions from net realized gains on investments, if any, will be
declared at least once each year.

- --------------------------------------------------------------------------------
Notes to Financial Statements (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 paydown gains and losses and 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.

            The Fund adjusts the classification of distributions to shareholders
to reflect the differences between financial statement amounts and distributions
determined in accordance with income tax regulations. Accordingly, during the
year ended September 30, 1998, amounts have been reclassified to reflect a
decrease in undistributed net investment income of $19,735,915, a decrease in
accumulated net realized loss on investments of $19,735,991, and a decrease in
paid-in capital of $76.

- --------------------------------------------------------------------------------
Other. Investment transactions are accounted for on the date the investments are
purchased or sold (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.

3. Unrealized Gains and Losses on Investments

As of September 30, 1998, net unrealized depreciation on investments and options
written of $443,996,869 was composed of gross appreciation of $314,116,994, and
gross depreciation of $758,113,863.

================================================================================
4. Management Fees and Other Transactions with Affiliates

Management fees paid to the Manager were in accordance with the investment
advisory agreement with the Fund which provides for a fee of 0.75% of the first
$200 million of the Fund's average annual net assets, 0.72% of the next $200
million, 0.69% of the next $200 million, 0.66% of the next $200 million, 0.60%
of the next $200 million and 0.50% of the average annual net assets in excess of
$1 billion. The Fund's management fee for the year ended September 30, 1998, was
0.52% of average annual net assets for Class A, Class B, Class C and Class Y
shares.

            For the year ended September 30, 1998, commissions (sales charges
paid by investors) on sales of Class A shares totaled $20,863,625, of which
$5,846,580 was retained by OppenheimerFunds Distributor, Inc. (OFDI), a
subsidiary of the Manager, as general distributor, and by an affiliated
broker/dealer. Sales charges advanced to broker/dealers by OFDI on sales of the
Fund's Class B and Class C shares totaled $46,878,475 and $3,717,936,
respectively, of which $1,547,059 and $121,658, respectively, was paid to an
affiliated broker/dealer. During the year ended September 30, 1998, OFDI
received contingent deferred sales charges of $8,531,853 and $287,953,
respectively, upon redemption of Class B and Class C shares as reimbursement for
sales commissions advanced by OFDI at the time of sale of such shares.

            OppenheimerFunds Services (OFS), a division of the Manager, is the
transfer and shareholder servicing agent for the Fund and for other Oppenheimer
funds. OFS's total costs of providing such services are allocated ratably to
these funds.

            The Fund has adopted a Service Plan for Class A shares to reimburse
OFDI for a portion of its costs incurred in connection with the personal service
and maintenance of shareholder accounts that hold Class A shares. Reimbursement
is made quarterly at an annual rate that may not exceed 0.25% of the average
annual net assets of Class A shares of the Fund. OFDI uses the service fee to
reimburse brokers, dealers, banks and other financial institutions quarterly for
providing personal service and maintenance of accounts of their customers that
hold Class A shares. During the year ended September 30, 1998, OFDI paid
$730,101 to an affiliated broker/dealer as reimbursement for Class A personal
service and maintenance expenses.

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

================================================================================
The Fund has adopted a Distribution and Service Plan for Class B shares to
reimburse OFDI for its costs in distributing Class B shares and servicing
accounts. Under the Plan, the Fund pays OFDI an annual asset-based sales charge
of 0.75% per year for its services rendered in distributing Class B shares. OFDI
also receives a service fee of 0.25% per year to reimburse dealers for providing
personal services for accounts that hold Class B shares. Each fee is computed on
the average annual net assets of Class B shares, determined as of the close of
each regular business day. During the year ended September 30, 1998, OFDI paid
$205,229 to an affiliated broker/dealer as reimbursement for Class B personal
service and maintenance expenses and retained $31,772,355 as reimbursement for
Class B sales commissions and service fee advances, as well as financing costs.
If the Plan is terminated by the Fund, the Board of Trustees may allow the Fund
to continue payments of the asset-based sales charge to OFDI for distributing
shares before the Plan was terminated. As of September 30, 1998, OFDI had
incurred excess distribution and servicing costs of $134,100,087 for Class B.

            The Fund has adopted a Distribution and Service Plan for Class C
shares to compensate OFDI for its costs in distributing Class C shares and
servicing accounts. Under the Plan, the Fund pays OFDI an annual asset-based
sales charge of 0.75% per year for its services rendered in distributing Class C
shares. OFDI also receives a service fee of 0.25% per year to compensate dealers
for providing personal services for accounts that hold Class C shares. Each fee
is computed on the average annual net assets of Class C shares, determined as of
the close of each regular business day. During the year ended September 30,
1998, OFDI paid $55,567 to an affiliated broker/dealer as compensation for Class
C personal service and maintenance expenses and retained $3,604,125 as
compensation for Class C sales commissions and service fee advances, as well as
financing costs. If the Plan is terminated by the Fund, the Board of Trustees
may allow the Fund to continue payments of the asset-based sales charge to OFDI
for distributing shares before the Plan was terminated. As of September 30,
1998, OFDI had incurred excess distribution and servicing costs of $9,740,259
for Class C.

================================================================================
5. Forward Contracts

A forward foreign currency exchange contract (forward contract) is a commitment
to purchase or sell a foreign currency at a future date, at a negotiated rate.

            The Fund uses forward contracts to seek to manage foreign currency
risks. They may also be used to tactically shift portfolio currency risk. The
Fund generally enters into forward contracts as a hedge upon the purchase or
sale of a security denominated in a foreign currency. In addition, the Fund may
enter into such contracts as a hedge against changes in foreign currency
exchange rates on portfolio positions.

5. Forward Contracts (continued)

Forward 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 or dealer. The Fund will realize a gain or loss upon
the closing or settlement of the forward transaction.

            Securities held in segregated accounts to cover net exposure on
outstanding forward contracts are noted in the Statement of Investments where
applicable. Unrealized appreciation or depreciation on forward contracts is
reported in the Statement of Assets and Liabilities. Realized gains and losses
are reported with all other foreign currency gains and losses in the Fund's
Statement of Operations.

            Risks include the potential inability of the counterparty to meet
the terms of the contract and unanticipated movements in the value of a foreign
currency relative to the U.S. dollar.

As of September 30, 1998, the Fund had outstanding forward contracts as follows:

6. Futures Contracts

The Fund may buy and sell interest rate futures contracts in order to gain
exposure to or protect against changes in interest rates. The Fund may also buy
and sell financial futures. The Fund may buy and sell futures contracts,
primarily to hedge the various commodities exposures inherent in its holdings of
structured notes that are linked to commodities indices. 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 or decreases in commodity prices and the resulting
negative effect on the value of fixed rate portfolio securities. The Fund may
also purchase futures contracts without owning the underlying fixed-income
security as an efficient or cost effective means to gain exposure to changes in
interest rate or commodity prices. The Fund will then either purchase the
underlying fixed-income security or close out the futures contact.

            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 recognizes 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 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.

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.


                      62 Oppenheimer Strategic Income Fund
<PAGE>
 
- --------------------------------------------------------------------------------

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

================================================================================
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
footnote 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 year ended September 30, 1998 was as follows:

8. Illiquid and Restricted Securities

As of September 30, 1998, investments in securities included issues that are
illiquid or restricted. Restricted securities are often purchased in private
placement transactions, are not registered under the Securities Act of 1933, may
have contractual restrictions on resale, and are valued under methods approved
by the Board of Trustees as reflecting fair value. 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 or restricted securities. Certain restricted
securities, eligible for resale to qualified institutional investors, are not
subject to that limit. The aggregate value of illiquid or restricted securities
subject to this limitation as of September 30, 1998 was $584,880,192, which
represents 6.76% of the Fund's net assets, of which $27,355,586 is considered
restricted.

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 0.35%. 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
0.0575% per annum.

            The Fund had no borrowings outstanding during the year ended
September 30, 1998.

Independent Auditors' Report
- --------------------------------------------------------------------------------

================================================================================
The Board of Trustees and Shareholders of
Oppenheimer Strategic Income Fund:

We have audited the accompanying statement of assets and liabilities, including
the statement of investments, of Oppenheimer Strategic Income Fund as of
September 30, 1998, the related statement of operations for the year then ended,
the statements of changes in net assets for the years ended September 30, 1998
and 1997, and the financial highlights for the period October 1, 1993, to
September 30, 1998. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

            We conducted our audits in accordance with generally accepted
auditing standards. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned at September 30, 1998, by correspondence with the custodian and brokers;
where replies were not received from brokers, we performed other auditing
procedures. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

            In our opinion, such financial statements and financial highlights
present fairly, in all material respects, the financial position of Oppenheimer
Strategic Income Fund at September 30, 1998, the results of its operations, the
changes in its net assets, and the financial highlights for the respective
stated periods, in conformity with generally accepted accounting principles.

Federal Income Tax Information (Unaudited)
- --------------------------------------------------------------------------------

================================================================================
In early 1999, shareholders will receive information regarding all dividends and
distributions paid to them by the Fund during calendar year 1998. Regulations of
the U.S. Treasury Department require the Fund to report this information to the
Internal Revenue Service.

            Dividends paid by the Fund during the fiscal year ended September
30, 1998, which are not designated as capital gain distributions should be
multiplied by 2.71% to arrive at the net amount eligible for the corporate
dividend-received deduction.

            The foregoing information is presented to assist shareholders in
reporting distributions received from the Fund to the Internal Revenue Service.
Because of the complexity of the federal regulations which may affect your
individual tax return and the many variations in state and local tax
regulations, we recommend that you consult your tax advisor for specific
guidance.
