Dear shareholder,
- --------------------------------------------------------------------------------
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financial plan is out-of-date or incomplete, now is the time to make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/ Bridget A.Macaskill

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

How did the Fund perform during the last twelve months?

Sharp declines in many of the world's markets hurt the performance of
Oppenheimer Multiple Strategies Fund during the one-year period ended September
30, 1998. Nevertheless, our strategy of broad diversification across asset
classes and investment styles enabled us to limit our losses and provide
investors with current income while taking advantage of opportunities that arose
in this very challenging environment.

What made this such a challenging period?

Asian markets experienced economic difficulties throughout the year. With no
resolution to Asia's problems in sight, and with Russia facing an economic and
political crisis of its own, investors began to lose confidence in emerging
markets throughout the world. As a result, emerging stock and bond markets
suffered sharp losses. The impact was felt in developed markets as well. Many
U.S. and European multinational companies saw profits decline as foreign demand
for products weakened. Financial institutions with exposure to emerging markets
suffered from concerns over asset quality.

     Within the United States, corporate profit growth slowed and average stock
prices fell sharply. Much of the equity market's remaining strength became
concentrated among the largest and most visible companies, though even that
segment showed increasing weakness and volatility. On the other hand, the U.S.
bond market responded favorably to an environment of slowing growth and
continuing low inflation. Long-term U.S. Treasury bonds performed well
throughout the period, providing investors with a combination of competitive
yields and capital appreciation.

How did the Fund allocate its assets during the period?

As of September 30, 1998, the Fund's invested assets were allocated 51% to
stocks, 43% to bonds and 6% to cash. Not surprisingly, considering its
diversified nature, the Fund shared in both the strengths and weaknesses of the
financial markets. By maintaining the Fund's exposure to a wide range of U.S.and
global equities and bonds, we enabled shareholders to participate in attractive
investment opportunities, while not putting too many eggs in any one basket.

     Looking ahead, we generally strive to maintain about an equal mix of
equities, fixed-income securities and cash. We believe this allocation will
enable us to produce attractive returns with low risks over a full market cycle.
We also believe this allocation will produce a portfolio that can perform well
in many different market environments.

What actions did you take in response to the equity market's volatility?

Because we were concerned about relatively high valuations in U.S. equities, we
sold some of our most successful holdings during the period to lock in profits.
We reallocated those assets to cash and the fixed-income markets. However, many
of our remaining positions suffered as equity markets weakened. For example, the
value of our technology holdings fell as a result of the crisis in Asia, a major
market for technology products.

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

Many of our financial stocks were negatively affected by concerns over their
exposure to emerging market loans. Oil service stocks dropped in the face of
slackening global energy demand and lower oil prices.

     We responded by focusing on high quality companies in areas that we believe
continue to hold significant potential for future growth. With stocks beaten
down throughout these sectors, many of the best companies in their respective
industries were available at prices we believed to be excellent values.
Therefore, we took the opportunity to trade up to companies we consider likely
to be among the first to rebound when conditions again become favorable.

     We also found selected opportunities in emerging markets. Stock prices in
many of these markets fell without regard for the strengths and weaknesses of
individual companies. Even companies with stable finances, recession-resistant
products and strong balance sheets saw their stock prices fall. We cautiously
explored these markets for such opportunities,and made small investments in a
few companies that met our criteria.

How did you manage the fixed-income portion of the Fund during the period?

Our approach to fixed-income investing is to diversify the Fund's assets among
U.S. Treasury securities, high-yield

2. Total returns include changes in share price and reinvestment of dividends
and capital gains distributions in a hypothetical investment for the periods
shown. Class A returns include the current maximum initial sales charge of
5.75%. Class A shares were first publicly offered on 4/24/87. The Fund's maximum
sales charge for Class A shares was lower prior to 4/1/91, so actual performance
may have been higher. Class B returns include the applicable contingent deferred
sales charge of 5% (1-year) and 3% (since inception on 8/29/95). Class C returns
for the one-year result include the contingent deferred sales charge of 1%.
Class C shares have an inception date of 12/1/93. Class B and C shares are
subject to an annual 0.75% asset-based sales charge. An explanation of the
different performance calculations is in the Fund's prospectus.

corporate bonds and foreign bonds.This approach enables us to capture extra
yield while reducing risks. That's because these three bond markets generally
react differently to changing environments. For example, within the U.S.
Treasury market, the greatest risk is maturity; within foreign markets, the
major risk is currency; and for high-yield corporate bonds, the greatest risk is
credit. By participating in all three markets, we've been able to earn
incrementally higher yields because we've always enjoyed some exposure to
whichever areas are performing best under existing conditions.

     As we mentioned earlier, the Fund's U.S. Treasuries holdings performed
particularly well this year. We also took advantage of volatility in overseas
fixed-income markets, particularly in Latin America.During the first half of
this fiscal year, we purchased Brady Bonds, which are U.S.dollar-denominated
bonds issued by Latin American governments and secured by the U.S.Federal
Reserve Bank. As the value of those bonds increased, we took the opportunity to
sell many. Now, the Asian crisis is creating new values in those same markets.
We are making opportunistic reinvestments in Brazil and certain other Latin
American countries. We believe these countries are likely to withstand their
current economic difficulties and eventually thrive because of their abundant
resources, growing populations and improving governments.

What is your outlook for the future?

We remain cautiously optimistic about the market's prospects over the coming
months. While many domestic equities still appear somewhat overvalued and
earnings growth seems to be slowing, market fundamentals, such as consumer
spending and money flows, remain strong.

And although Asian economies and Russia continue to struggle, the rest of the
world has thus far weathered the situation fairly well. In Europe, companies are
beginning to benefit from the management changes and corporate restructurings
that helped U.S. companies become more efficient over the past decade. Latin
America has also learned some difficult lessons and appears to be on track
toward better economic growth.

     The last twelve months of volatility and uncertainty illustrate the
importance of a broad-based investment strategy. We remain dedicated to our
highly diversified approach as we face the challenges ahead, searching for
attractive investments throughout the world. It's a strategy that in the past
has generally served our shareholders well...and that we believe continues to
make Oppenheimer Multiple Strategies Fund part of The Right Way to Invest.

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.

     . Management's Discussion of Performance. During the past fiscal year that
ended September 30, 1998, weakness in Asian economies and pressures on corporate
earnings introduced greater volatility into equities markets, causing the Fund's
overall performance to suffer. However, the Fund's losses were limited by strong
bond performance, especially in U.S. Treasury securities, driven by low rates of
inflation. The Fund also realized profits from its investments in U.S. corporate
and Latin American bonds. We found opportunities to take profits in some of the
Fund's best-performing stock holdings. Falling prices in certain sectors,
including technology, finance and oil service, provided opportunities to shift
assets to higher quality holdings within the same sector. The Fund's portfolio
and our management strategies are subject to change.

     . Comparing the Fund's Performance to the Market. The graphs that follow
show the performance of a hypothetical $10,000 investment in Class A, Class B
and Class C shares of the Fund held until September 30, 1998. In the case of
Class A shares, performance is measured over a 10-year period. In the case of
Class B shares, performance is measured from inception of the Class on August
29, 1995. In the case of Class C shares, performance is measured from inception
of the Class on December 1, 1993. The Fund's performance reflects the deduction
of the 5.75% maximum initial sales charge on Class A shares, the 5% (1-year) and
3% (since inception) applicable contingent deferred sales charge for Class B,
and the 1% (1-year) contingent deferred sales charge for Class C shares. The
graphs assume that all dividends and capital gains distributions were reinvested
in additional shares.

     Because the Fund invests in a variety of equity and fixed income
securities, the Fund's performance is compared to the performance of two
indices: (i) the Standard & Poor's (S&P) 500 Index, a broad-based index of
equity securities widely regarded as a general measure of the performance of the
U.S. equity securities market; and (ii) the Lehman Brothers Aggregate Bond
Index, an unmanaged index of U.S. Government Treasury and agency issues,
investment grade corporate bond issues and fixed rate mortgage-backed
securities. That index is widely regarded as a measure of the performance of the
domestic debt securities market.

     Index performance reflects the reinvestment of dividends 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 or
countries in the indices.

4. Interest or dividend is paid-in-kind.

5. 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 $6,531,248 or 0.88% of the Fund's net
assets as of September 30, 1998.

6. Face amount is reported in U.S. Dollars, except for those denoted in the
following currencies:

ARP--Argentine Peso                       GBP--British Pound Sterling
AUD--Australian Dollar                    ITL--Italian Lira
CAD--Canadian Dollar                      NOK--Norwegian Krone
DEM--German Mark                          NZD--New Zealand Dollar
DKK--Danish Krone                         PLZ--Polish Zloty
ESP--Spanish Peseta                       ZAR--South African Rand
FIM--Finnish Markka

7. 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.

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

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

10. Represents the current interest rate for an increasing rate security.

11. Denotes a step bond: a zero coupon bond that converts to a fixed or variable
interest rate at a designated future date.

12. Units may be comprised of several components, such as debt and equity
and/or warrants to equity at some point in the future. For units which represent
debt securities, face amount disclosed represents total underlying principal.

================================================================================
1. Significant Accounting Policies
Oppenheimer Multiple Strategies Fund (the Fund) is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund's investment objective is to seek high
total investment return consistent with preservation of principal. 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 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 distribution and/or
service plan, expenses directly attributable to that class and exclusive voting
rights with respect to matters affecting that class. 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 an 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.
- --------------------------------------------------------------------------------
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 rate 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.
- --------------------------------------------------------------------------------
Trustees' Fees and Expenses. The Fund has adopted a nonfunded retirement plan
for the Fund's independent Trustees. Benefits are based on years of service and
fees paid to each Trustee during the years of service. During the year ended
September 30, 1998, a credit of $64,022 was made for the Fund's projected
benefit obligations, and payments of $9,051 were made to retired Trustees,
resulting in an accumulated liability of $189,122 as of September 30, 1998.

            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 fees 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 Trustee in shares of one or more Oppenheimer
funds selected by the Trustee. The amount paid to the Trustee 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 income per
share.

Notes to Financial Statements (Continued)
================================================================================

================================================================================
1. Significant Accounting Policies  (continued)
Distributions to Shareholders. Dividends and distributions to shareholders are
recorded on the ex-dividend date.
- --------------------------------------------------------------------------------
Classification of Distributions to Shareholders. Net investment income (loss)
and net realized gain (loss) may differ for financial statement and tax purposes
because of the recognition of certain foreign currency gains (losses) as
ordinary income (loss) for tax purposes. The character of the 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 an
increase in paid-in capital of $591,836, a decrease in undistributed net
investment income of $159,958, and a decrease in accumulated net realized gain
on investments of $431,878.
- --------------------------------------------------------------------------------
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.

4.  Management Fees and Other Transactions with Affiliates
Management fees paid to the Manager are in accordance with the investment
advisory agreement with the Fund which provides for a fee of 0.75% on the first
$200 million of average annual net assets, 0.72% on the next $200 million, 0.69%
of the next $200 million, 0.66% of the next $200 million, 0.60% of the next $700
million, and 0.58% of average annual net assets in excess of $1.5 billion. The
agreement was amended per resolutions adopted by the Board of Trustees on
December 11, 1997 to add the final breakpoint of 0.58% on average annual net
assets in excess of $1.5 billion.

             For the year ended September 30, 1998, commissions (sales charges
paid by investors) on sales of Class A shares totaled $910,294, of which 
$288,141 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 $878,710 and $134,394, respectively, of which $47,196
and $3,702, respectively, was paid to an affiliated broker/dealer. During the
year ended September 30, 1998, OFDI received contingent deferred sales charges
of $164,466 and $11,263, 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 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 
$83,283 to an affiliated broker/dealer as reimbursement for Class A personal
service and maintenance expenses.

             The Fund has adopted Distribution and Service Plans for Class B and
Class C shares to compensate OFDI for its costs in distributing Class B and
Class C shares and servicing accounts. Under the Plans, the Fund pays OFDI an
annual asset-based sales charge of 0.75% per year on Class B and Class C shares
for its services rendered in distributing Class B and 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 B and C shares. Each fee is
computed on the average annual net assets of Class B or Class C shares,
determined as of the close of each regular business day. During the

================================================================================

================================================================================

================================================================================
year ended September 30, 1998, OFDI paid $7,327 and $14,113, respectively, to an
affiliated broker/dealer as compensation for Class B and Class C personal
service and maintenance expenses and retained $618,987 and $227,791,
respectively, as compensation for Class B and Class C sales commissions and
service fee advances, as well as financing costs. If either 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 $2,811,387 for Class B and $576,876 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.

            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. 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 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:

7. 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 $3,332,413,
which represents 0.45% of the Fund's net assets.

8. Acquisition of Oppenheimer Fund and Oppenheimer Strategic Income & Growth
   Fund
On June 20, 1997, the Fund acquired all the net assets of Oppenheimer Fund,

$45,364,088 on June 20, 1997. The net assets acquired included net unrealized

================================================================================
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 Multiple Strategies Fund:

We have audited the accompanying statements of investments and assets and
liabilities of Oppenheimer Multiple Strategies Fund as of September 30, 1998,
and the related statement of operations for the year then ended, the statements
of changes in net assets for each of the years in the two-year period then
ended, and the financial highlights for each of the years in the two-year period
then ended, the nine-month period ended September 30, 1996, and each of the
years in the three-year period ended December 31, 1995. 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 as of September 30, 1998, by correspondence with the custodian and
brokers; and where confirmations 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, the financial statements and financial highlights
referred to above present fairly, in all material respects, the financial
position of Oppenheimer Multiple Strategies Fund as of September 30, 1998, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years in the two-year period then ended, the
nine-month period ended September 30, 1996, and each of the years in the
three-year period ended December 31, 1995, 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.

            Distributions of $1.3978, $1.3599 and $1.3596 per share were paid to
Class A, Class B and Class C shareholders, respectively, on December 19, 1997,
of which, for each class of shares, $0.2933 was designated as a capital gain
distribution in the "28% Rate Group" and $0.7208 was designated as a capital
gain distribution in the "20% Rate Group" for federal income tax purposes.
Whether received in stock or cash, the capital gain distribution should be
treated by shareholders as a gain from the sale of capital assets.

             Dividends paid by the Fund during the year ended September 30,
1998, which are not designated as capital gain distributions should be
multiplied by 21.82% 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.
