FUND PERFORMANCE DISCUSSION


How Has the Fund Performed? Below is a discussion, by OppenheimerFunds, Inc., of
the Fund's performance during its fiscal year ended August 31, 2003, followed by
a graphical comparison of the Fund's performance to an appropriate broad-based
market index.
Management's Discussion of Fund Performance. Oppenheimer Developing Markets
Fund Class A shares returned 27.93% (without sales charge) for the
fiscal year ended August 31, 2003. This compares to a one-year total
return of 29.27% for its benchmark index, the Morgan Stanley Capital
International (MSCI) Emerging Markets Free Index. The Fund considered the effect
of worldwide growth themes and sought to identify what are believed to be
well-managed, reasonably valued companies that may benefit from these themes.
   The largest country weights in the Fund for the period were in India, South
Korea, Brazil and Mexico, where the Fund continued to find opportunities to
invest in good business at good prices. Our investment decisions were made
through a bottom-up approach with the primary consideration being the company in
which we invest. We found more companies in the above countries to be
interesting investments because of the price structures, risk/reward profiles
and overall quality of companies available there.
   The Fund owned fewer companies directly in Russia and China compared with the
benchmark index during the period because of our concerns with the quality of
information, legal structure and corporate governance regulations in both of
these countries. While these markets experienced significant growth during the
period, the Fund was unable to find suitable investments that fulfilled the
Fund's quality criteria for risk/reward profile, valuation, financial reporting
or shareholder protection.
   Among the Fund's principal individual contributors was application software
company Amdocs Ltd. The Israel-based provider of customer care and billing
services to the telecommunications industry had a strong balance sheet,
high-quality customer base and was available at what we regarded was an
attractive multiple. The stock price rebounded from its lows as telecom
companies continued to spend money on a key source of their competitive
advantage, customer care. Next, Mexico's leading low-cost housing developer
Corporacion GEO SA de CV benefited from the availability of cheaper credit to
the housing market and a government commitment to increase the levels of home
ownership in the country. In a similar vein, Housing Development Finance Corp.
Ltd, India's largest and lowest cost home mortgage lender, advanced as economic
conditions and declining interest rates boosted demand. Another contributor was
Brazilian supermarket operator Lojas Americanas SA, where management efforts in
restructuring and cost cutting, as well as store remodeling led to higher sales
profits.

FUND PERFORMANCE DISCUSSION


   In contrast, LG Home Shopping, Inc., a leading South Korean home shopping
network, came under severe pressure as rising defaults forced the government to
intervene in the issuance of personal credit cards. While headline events
deflated consumer confidence, increased competition also factored into the
stock's decline. Given the excellent long-term profile for the company, we
believed this setback is merely temporary. Taiwanese convenience store operator
President Chain Store Corporation also fell when investors questioned its
involvement in a larger-scale mall project. In light of continued strong cash
flow generation in its core business, the Fund has used recent declines to
increase its position.
   Country, industry sector and market capitalization weightings were the result
of individual stock selection and do not reflect predetermined target
allocations. The Fund's holdings, allocations, management and strategies are
subject to change. Investing in emerging market securities poses considerable
risks, including heightened volatility, political and economic uncertainty,
currency fluctuations and higher expenses.
   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 from the inception date of November 18, 1996
until August 31, 2003. In the case of Class N shares, performance is measured
from inception of the Class on March 1, 2001. The Fund's performance reflects
the deduction of the maximum initial sales charge on Class A shares, the
applicable contingent deferred sales charge on Class B, Class C and Class N
shares, and reinvestment of all dividends and capital gains distributions.
   The Fund's performance is compared to the performance of the Morgan Stanley
Capital International (MSCI) Emerging Markets Free Index, an unmanaged
capitalization-weighted equity index of issuers located in 25 developing
markets. The MSCI Emerging Markets Free Index is widely recognized as a measure
of performance in developing markets. 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 show the effect of taxes.
The Fund's performance reflects the effect 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 index shown.

NOTES


In reviewing performance and rankings, please remember that past performance
cannot guarantee future results. Investment return and principal value of an
investment in the Fund will fluctuate so that an investor's shares, when
redeemed, may be worth more or less than the original cost. Because of ongoing
market volatility, the Fund's performance may be subject to substantial
fluctuations, and current performance may be more or less than the results
shown. For updates on the Fund's performance, visit our website at
www.oppenheimerfunds.com.

Total returns and the ending account values in the graph includes changes in
share price and reinvestment of dividends and capital gains distributions in a
hypothetical investment for the periods shown. The Fund's total returns shown do
not reflect the deduction of income taxes on an individual's investment. Taxes
may reduce your actual investment returns on income or gains paid by the Fund or
any gains you may realize if you sell your shares. For more complete information
about the Fund, including charges, expenses and risks, please refer to the
prospectus. To obtain a copy, call your financial advisor, call OppenheimerFunds
Distributor, Inc. at 1.800.CALL OPP (1.800.225.5677). Read the prospectus
carefully before you invest or send money.

Class A shares of the Fund were first publicly offered on 11/18/96. Unless
otherwise noted, Class A returns include the maximum initial sales charge of
5.75%.

Class B shares of the Fund were first publicly offered on 11/18/96. Unless
otherwise noted, Class B returns include the applicable contingent deferred
sales charge of 5% (1-year) and 2% (5-year). Because Class B shares convert to
Class A shares 72 months after purchase, the "since inception" return for Class
B uses Class A performance for the period after conversion. Class B shares are
subject to an annual 0.75% asset-based sales charge.

Class C shares of the Fund were first publicly offered on 11/18/96. Unless
otherwise noted, Class C returns include the contingent deferred sales charge of
1% for one-year period. Class C shares are subject to a 0.75% annual asset-based
sales charge.

Class N shares of the Fund were first publicly offered on 3/1/01.Class N shares
are offered only through retirement plans. Unless otherwise noted, Class N
returns include the contingent deferred sales charge of 1% for the 1-year
period. Class N shares are subject to an annual 0.25% asset-based sales charge.

An explanation of the calculation of performance is in the Fund's Statement of
Additional Information.

NOTES TO FINANCIAL STATEMENTS



- --------------------------------------------------------------------------------
 1. Significant Accounting Policies
 Oppenheimer Developing Markets 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 aggressively seek
 capital appreciation. The Fund's investment advisor is OppenheimerFunds, Inc.
 (the Manager).
    The Fund offers Class A, Class B, Class C and Class N shares. Class A shares
 are sold at their offering price, which is normally net asset value plus a
 front-end sales charge. Class B, Class C and Class N shares are sold without a
 front-end sales charge but may be subject to a contingent deferred sales charge
 (CDSC). Class N shares are sold only through retirement plans. Retirement plans
 that offer Class N shares may impose charges on those accounts. All classes of
 shares have identical rights and voting privileges. Earnings, net assets and
 net asset value per share may differ by minor amounts due to each class having
 its own expenses directly attributable to that class. Classes A, B, C and N
 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 Fund assesses a 2% fee on the proceeds of fund shares that are redeemed
 (either by selling or exchanging to another Oppenheimer fund) within 30 days of
 their purchase. The fee, which is retained by the Fund, is accounted for as an
 addition to paid-in capital.
    The following is a summary of significant accounting policies consistently
 followed by the Fund.
- --------------------------------------------------------------------------------
 Securities Valuation. Securities listed or traded on National Stock Exchanges
 or other domestic or foreign exchanges are valued based on the last sale price
 of the security traded on that exchange prior to the time when the Fund's
 assets are valued. Securities traded on NASDAQ are valued based on the closing
 price provided by NASDAQ prior to the time when the Fund's assets are valued.
 In the absence of a sale, the security is valued 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 using consistently applied procedures under the supervision of the Board
 of Trustees. Short-term "money market type" debt securities with remaining
 maturities of sixty days or less are valued at amortized cost (which
 approximates market value).
- --------------------------------------------------------------------------------
 Foreign Currency Translation. The Fund's accounting records 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.

NOTES TO FINANCIAL STATEMENTS  Continued


- --------------------------------------------------------------------------------
 1. Significant Accounting Policies Continued
    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.
- --------------------------------------------------------------------------------
 Joint Repurchase Agreements. Pursuant to an Exemptive Order issued by the
 Securities and Exchange Commission, the Fund, along with other affiliated funds
 advised by the Manager, may transfer uninvested cash balances into joint
 trading accounts on a daily basis. Secured by U.S. government securities, these
 balances are invested in one or more repurchase agreements. Securities pledged
 as collateral for repurchase agreements are held by a custodian bank until the
 agreements mature. Each agreement requires that the market value of the
 collateral be sufficient to cover payments of interest and principal. In the
 event of default by the other party to the agreement, retention of the
 collateral may be subject to legal proceedings.
- --------------------------------------------------------------------------------
 Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than
 those attributable to a specific class), gains and losses are allocated on a
 daily basis 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 comply with provisions of the Internal
 Revenue Code applicable to regulated investment companies and to distribute
 substantially all of its investment company taxable income, including any net
 realized gain on investments not offset by capital loss carryforwards, if any,
 to shareholders, therefore, no federal income or excise tax provision is
 required.

 The tax components of capital shown in the table below represent distribution
 requirements the Fund must satisfy under the income tax regulations, losses the
 Fund may be able to offset against income and gains realized in future years
 and unrealized appreciation or depreciation of investment for federal income
 tax purposes.

1. As of August 31, 2003, the Fund had $19,295,605 of net capital loss
carryforwards available to offset future realized capital gains, if any, and
thereby reduce future taxable gain distributions. As of August 31, 2003, details
of the capital loss carryforwards were as follows:

                              Expiring

2. During the fiscal years ended August 31, 2003 and August 31, 2002, the Fund
did not utilize any capital loss carryforwards.
3. As of August 31, 2003, the Fund had $12,594,237 of post-October losses
available to offset future realized capital gains, if any. Such losses, if
unutilized, will expire in 2012.

Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Fund. Accordingly, the
following amounts have been reclassified for August 31, 2003. Net assets of the
Fund were unaffected by the reclassifications.

     From                 To                             Net

 The aggregate cost of investments and the composition of unrealized
 appreciation and depreciation of investments for federal income tax purposes as
 of August 31, 2003 are noted below. The primary difference between book and tax
 appreciation or depreciation of investments, if applicable, is attributable to
 the tax deferral of losses or tax realization of financial statement unrealized
 gain or loss.

NOTES TO FINANCIAL STATEMENTS  Continued



- --------------------------------------------------------------------------------
 1. Significant Accounting Policies Continued
 Certain foreign countries impose a tax on capital gains which is accrued by the
 Fund based on unrealized appreciation, if any, on affected securities. The tax
 is paid when the gain is realized.
- --------------------------------------------------------------------------------
 Trustees' Compensation. The Fund has adopted an unfunded 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
 August 31, 2003, the Fund's projected benefit obligations were increased by
 $8,677 and payments of $1,368 were made to retired trustees, resulting in an
 accumulated liability of $44,365 as of August 31, 2003.
    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 the annual compensation they are entitled to receive from the
 Fund. Under the plan, deferred amounts are treated as though equal dollar
 amounts had been invested in shares of the Fund or are invested in other
 selected Oppenheimer 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. Amounts will be
 deferred until distributed in accordance to the Plan.
- --------------------------------------------------------------------------------
 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. Income and capital gain distributions, if
 any, are declared and paid annually.
- --------------------------------------------------------------------------------
 Investment Income. Dividend income is recorded on the ex-dividend date or upon
 ex-dividend notification in the case of certain foreign dividends where the
 ex-dividend date may have passed. Non-cash dividends included in dividend
 income, if any, are recorded at the fair market value of the securities
 received. Interest income, which includes accretion of discount and
 amortization of premium, is accrued as earned.
- --------------------------------------------------------------------------------
 Expense Offset Arrangement. The reduction of custodian fees represents earnings
 on cash balances maintained by the Fund.
- --------------------------------------------------------------------------------
 Security Transactions. Security transactions are recorded on the trade date.
 Realized gains and losses on securities sold are determined on the basis of
 identified cost.
- --------------------------------------------------------------------------------
 Other. The preparation of financial statements in conformity with accounting
 principles generally accepted in the United States of America 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.

 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 to settle specific purchases or sales of securities
 denominated in a foreign currency and for protection from adverse exchange rate
 fluctuation. 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 prevailing foreign currency exchange rates.
 Unrealized appreciation and depreciation on foreign currency contracts are
 reported in the Statement of Assets and Liabilities as a receivable or payable
 and in the Statement of Operations with the change in unrealized appreciation
 or depreciation.
    The Fund may realize a gain or loss upon the closing or settlement of the
 foreign transaction. Contracts closed or settled with the same broker are
 recorded as net realized gain or loss. Such realized gains and losses are
 reported with all other foreign currency gains and losses in the Statement of
 Operations.

 As of August 31, 2003, the Fund had outstanding foreign currency contracts as
 follows:



                                         Contract            Valuation
                           Expiration      Amount                as of          Unrealized           Unrealized

- --------------------------------------------------------------------------------
 6. Illiquid Securities
 As of August 31, 2003, 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 15% 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 August
 31, 2003 was $36,546,349, which represents 4.82% of the Fund's net assets.



                    29 | OPPENHEIMER DEVELOPING MARKETS FUND


NOTES TO FINANCIAL STATEMENTS  Continued



- --------------------------------------------------------------------------------
 7. Borrowing and Lending Arrangements
 The Fund entered into an "interfund borrowing and lending arrangement" with
 other funds in the Oppenheimer funds complex, to allow funds to borrow for
 liquidity purposes. The arrangement was initiated pursuant to exemptive relief
 granted by the Securities and Exchange Commission to allow these affiliated
 funds to lend money to, and borrow money from, each other, in an attempt to
 reduce borrowing costs below those of bank loan facilities. Under the
 arrangement the Fund may lend money to other Oppenheimer funds and may borrow
 from other Oppenheimer funds at a rate set by the Fund's Board of Trustees,
 based upon a recommendation by the Manager. The Fund's borrowings, if any, are
 subject to asset coverage requirements under the Investment Company Act and the
 provisions of the SEC order and other applicable regulations. If the Fund
 borrows money, there is a risk that the loan could be called on one day's
 notice, in which case the Fund might have to borrow from a bank at higher rates
 if a loan were not available from another Oppenheimer fund. If the Fund lends
 money to another fund, it will be subject to the risk that the other fund might
 not repay the loan in a timely manner, or at all.
    The Fund had no interfund borrowings or loans outstanding during the year
 ended or at August 31, 2003.

    We conducted our audits in accordance with auditing standards generally
 accepted in the United States of America. 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 August 31, 2003, by
 correspondence with the custodian and brokers or by other appropriate auditing
 procedures where replies from brokers were not received. 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 Developing Markets Fund as of August 31, 2003, the results of its
 operations for the year then ended, the changes in its net assets for each of

 FEDERAL INCOME TAX INFORMATION  Unaudited


- --------------------------------------------------------------------------------
 In early 2004, if applicable, shareholders of record will receive information
 regarding all dividends and distributions paid to them by the Fund during
 calendar year 2003. Regulations of the U.S. Treasury Department require the
 Fund to report this information to the Internal Revenue Service.
    Dividends of $0.1966, $0.0939, $0.1241 and $0.2229 per share were paid to
 Class A, Class B, Class C and Class N shareholders, respectively, on December
 12, 2002, all of which was designated as "ordinary income" for federal income
 tax purposes.
    None of the dividends paid by the Fund during the year ended August 31, 2003
 are eligible for the corporate dividend-received deduction.
    A portion of the dividends paid by the Fund during the fiscal year ended
 August 31, 2003 which are not designated as capital gain distributions are
 eligible for lower individual income tax rates to the extent that the Fund has
 received qualified dividend income as stipulated by recent tax legislation.
 $17,402,617 of the Fund's fiscal year taxable income is eligible for the lower
 individual income tax rates. In early 2004, shareholders of record will receive
 information regarding the percentage of distributions that are eligible for
 lower individual income tax rates.
    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.
