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, 2006, FOLLOWED BY
A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE BROAD-BASED
MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. We were quite pleased with our
performance during the reporting period, given the strong absolute return of
28.41% for Class A shares (without sales charge) for the 12-month period ended
August 31, 2006. On a relative basis, we outperformed the average Lipper
competitor, placing us in the 2nd quartile of performance.

      The biggest drivers of that relative outperformance were the Industrials
and Materials sectors where our stock selection proved very strong. Our best
performing Industrial stock was Motech Industries, Inc., a solar panel display
manufacturer. Motech was up 86% during the reporting period. In Materials, PT
Aneka Tambang Tbk and Anglo Platinum Ltd. drove performance.

      From a country perspective Brazil and Taiwan were our best performing
countries. In both cases a mix of stock selection and country allocation boosted
results. Allocation played a more prominent role in Taiwan where our underweight
in the latter half of last year (a period where that market significantly
underperformed) helped the Fund.

      Relative to the benchmark, the Morgan Stanley Capital International (MSCI)
Emerging Markets Index, the biggest drag on performance was the Energy sector,
where our lack of Russian holdings cost the Fund 162 basis points in
performance. The Fund has historically avoided Russia because of the appalling
status of minority shareholders and the extremely opaque governance structure at
its leading energy companies. In the past we have been able to compensate for
our underexposure, even with Russia's strong performance, with other holdings.
However, with such strong outperformance for the Russian energy sector in the
reporting period, we were only able to perform in line with our peers. We look
forward to improved governance conditions in the Russian energy sector; a
development which may be hastened by a correction in commodity prices.

      Another underperforming sector for the Fund was Consumer Staples. Here we
were hurt by poor stock selection in which holdings such as Companhia Brasileira
de Distribuicao Grupo Pao de Acucar (a Brazilian grocer) and President Chain
Store Corp. (a collection of convenience stores in Taiwan and China) posted poor
results. CBD was hurt by a shift in consumption away from staples and to
durables (a phenomena which helped other holdings in the portfolio such as Lojas
Americanas SA) while President Chain was hurt by weak consumer spending in
Taiwan; itself a function of a deep political crisis in which the Prime Minister
narrowly avoided impeachment, as well as concerns on relations with China.


                    12 | OPPENHEIMER DEVELOPING MARKETS FUND


      The worst performing countries were Russia, for reasons discussed earlier,
and Korea. Ssangyong Motor Co., one of Korea's auto manufacturers, was a poor
performer in the portfolio. In addition to weakening demand for autos caused by
the rise in oil prices and a slowdown in Korean spending, attempts by the
company to cut back on production were blocked by challenges from union workers.
However, Ssangyong is a solid growth story, whose recent underperformance has
led us to add to our position in the stock.

      In closing, we'd like to remind shareholders that investing in foreign
markets, especially in the securities of emerging countries, 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 each class of shares of the
Fund held until August 31, 2006. In the case of Class A, Class B and Class C
shares, performance is measured from the inception of the Classes on November
18, 1996. In the case of Class N shares, performance is measured from inception
of the Class on March 1, 2001. In the case of Class Y shares, performance is
measured from inception of the Class on September 7, 2005. 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 reinvestments of all dividends and capital gains
distributions. Past performance cannot guarantee future results.

      The Fund's performance is compared to the performance of the Morgan
Stanley Capital International (MSCI) Emerging Markets Index, an unmanaged
capitalization-weighted equity index of issuers located in 26 developing
markets. The MSCI Emerging Markets Index is widely recognized as a measure of
performance in developing markets. Index performance reflects the reinvestment
of income but does not consider the effect of transaction costs, and none of the
data in the graphs shows the effect of taxes. The Fund's performance reflects
the effects of the Fund's 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 investments in
the index.

INVESTMENT IN THE FUND WILL FLUCTUATE SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. CURRENT
PERFORMANCE MAY BE LOWER OR HIGHER THAN THE PERFORMANCE QUOTED. FOR PERFORMANCE
DATA CURRENT TO THE MOST RECENT MONTH END, VISIT US AT WWW.OPPENHEIMERFUNDS.COM,
OR CALL US AT 1.800.525.7048. FUND RETURNS INCLUDE CHANGES IN SHARE PRICE,
REINVESTED DISTRIBUTIONS, AND THE APPLICABLE SALES CHARGE: FOR CLASS A SHARES,
THE CURRENT MAXIMUM INITIAL SALES CHARGE OF 5.75%; FOR CLASS B SHARES, THE
CONTINGENT DEFERRED SALES CHARGE OF 5% (1-YEAR) AND 2% (5-YEAR); AND FOR CLASS C
AND N SHARES, THE CONTINGENT 1% DEFERRED SALES CHARGE FOR THE 1-YEAR PERIOD.
BECAUSE CLASS B SHARES CONVERT TO CLASS A SHARES 72 MONTHS AFTER PURCHASE, SINCE
INCEPTION RETURNS FOR CLASS B SHARES USES CLASS A PERFORMANCE FOR THE PERIOD
AFTER CONVERSION. THERE IS NO SALES CHARGE FOR CLASS Y SHARES. SEE PAGE 19 FOR
FURTHER INFORMATION.

Total returns and the ending account values in the graphs include 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.

INVESTORS SHOULD CONSIDER THE FUND'S INVESTMENT OBJECTIVES, RISKS, AND OTHER
CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. THE FUND'S PROSPECTUS CONTAINS
THIS AND OTHER INFORMATION ABOUT THE FUND, AND MAY BE OBTAINED BY ASKING YOUR
FINANCIAL ADVISOR, CALLING US AT 1.800.525.7048 OR VISITING OUR WEBSITE AT

CLASS B shares of the Fund were first publicly offered on 11/18/96. Unless

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

FUND EXPENSES
- --------------------------------------------------------------------------------

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include sales charges (loads) on purchase payments,
contingent deferred sales charges on redemptions; and redemption fees, if any;
and (2) ongoing costs, including management fees; distribution and service fees;
and other Fund expenses. These examples are intended to help you understand your
ongoing costs (in dollars) of investing in the Fund and to compare these costs
with the ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended August 31, 2006.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line for the class of shares you hold, together with the amount you invested, to
estimate the expense that you paid over the period. Simply divide your account
value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00
= 8.60), then multiply the result by the number in the "actual" line under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the Fund's actual expense ratio for each class of shares, and
an assumed rate of return of 5% per year before expenses, which is not the
Fund's actual return. The hypothetical account values and expenses may not be
used to estimate the actual ending account balance or expenses you paid for the
period. You may use this information to compare the ongoing costs of investing
in the Fund and other funds. To do so, compare this 5% hypothetical example for
the class of shares you hold with the 5% hypothetical examples that appear in
the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as front-end
or contingent deferred sales charges (loads), redemption fees, or a $12.00 fee
imposed annually on accounts valued at less than $500.00 (subject to


                    21 | OPPENHEIMER DEVELOPING MARKETS FUND


FUND EXPENSES
- --------------------------------------------------------------------------------

exceptions described in the Statement of Additional Information). Therefore, the
"hypothetical" lines of the table are useful in comparing ongoing costs only,
and will not help you determine the relative total costs of owning different
funds. In addition, if these transactional costs were included, your costs would
have been higher.

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 184/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended August 31, 2006 are as follows:

CLASS           EXPENSE RATIOS
- ------------------------------
Class A             1.39%
- ------------------------------
Class B             2.16
- ------------------------------
Class C             2.11
- ------------------------------
Class N             1.79
- ------------------------------
Class Y             0.98

The expense ratios reflect voluntary waivers or reimbursements of expenses by
the Fund's Manager and Transfer Agent that can be terminated at any time,
without advance notice. The "Financial Highlights" tables in the Fund's
financial statements, included in this report, also show the gross expense
ratios, without such waivers or reimbursements.

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, Class N and Class Y 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. Class Y shares are sold to certain institutional investors without
either a front-end sales charge or a CDSC, however, the institutional investor
may impose charges on those accounts. All classes of shares have identical
rights and voting privileges with respect to the Fund in general and exclusive
voting rights on matters that affect that class alone. Earnings, net assets and
net asset value per share may differ due to each class having its own expenses,
such as transfer and shareholder servicing agent fees and shareholder
communications, directly attributable to that class. Class A, B, C and N 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 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. The Fund calculates the net asset value of its shares as
of the close of the New York Stock Exchange (the "Exchange"), normally 4:00 P.M.
Eastern time, on each day the Exchange is open for business. Securities may be
valued primarily using dealer-supplied valuations or a portfolio pricing service
authorized by the Board of Trustees. Securities listed or traded on National
Stock Exchanges or other domestic 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(R) 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 traded on
foreign exchanges are valued based on the last sale price on the principal
exchange on which the security is traded, as identified by the portfolio pricing
service, prior to the time when the Fund's assets are valued. In the absence of
a sale, the security is valued at the official closing price on the principal
exchange. Corporate, government and municipal debt instruments having a
remaining maturity in excess of sixty days and all mortgage-backed securities

1. SIGNIFICANT ACCOUNTING POLICIES Continued

will be valued at the mean between the "bid" and "asked" prices. Futures
contracts traded on a commodities or futures exchange will be valued at the
final settlement price or official closing price on the principal exchange as
reported by such principal exchange at its trading session ending at, or most
recently prior to, the time when the Fund's assets are valued. Securities
(including restricted securities) for which market quotations are not readily
available are valued at their fair value. Foreign and domestic securities whose
values have been materially affected by what the Manager identifies as a
significant event occurring before the Fund's assets are valued but after the
close of their respective exchanges will be fair valued. 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. The values of securities denominated in foreign currencies and
amounts related to the purchase and sale of foreign securities and foreign
investment income are translated into U.S. dollars as of the close of the New
York Stock Exchange (the "Exchange"), normally 4:00 P.M. Eastern time, on each
day the Exchange is open for business. Foreign exchange rates may be valued
primarily using dealer supplied valuations or a portfolio pricing service
authorized by the Board of Trustees.

      Reported net realized foreign exchange gains or losses arise from sales of
portfolio securities, sales and maturities of short-term securities, sales of
foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, and the difference between the
amounts of dividends, interest, and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains and losses arise from changes in the
values of assets and liabilities, including investments in securities at fiscal
period end, resulting from changes in exchange rates.

      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. 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.


                    44 | OPPENHEIMER DEVELOPING MARKETS FUND


- --------------------------------------------------------------------------------
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 securities and other investments for
federal income tax purposes.

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, 2006. Net assets of the

The aggregate cost of securities and other investments and the composition of
unrealized appreciation and depreciation of securities and other investments for
federal income tax purposes as of August 31, 2006 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and

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, 2006, the Fund's projected benefit obligations were increased by $361,563
and payments of $21,653 were made to retired trustees, resulting in an
accumulated liability of $463,502 as of August 31, 2006.

      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.
For purposes of determining the amount owed to the Trustee under the plan,
deferred amounts are treated as though equal dollar amounts had been invested in
shares of the Fund or in other Oppenheimer funds selected by the Trustee. The
Fund purchases shares of the funds selected for deferral by the Trustee in
amounts equal to his or her deemed investment, resulting in a Fund asset equal
to the deferred compensation liability. Such assets are included as a component
of "Other" within the asset section of the Statement of Assets and Liabilities.
Deferral of trustees' fees under the plan will not affect the net assets of the
Fund, and


                    46 | OPPENHEIMER DEVELOPING MARKETS FUND


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.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may
include interest expense incurred by the Fund on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Fund pays
interest to its custodian on such cash overdrafts, to the extent they are not
offset by positive cash balances maintained by the Fund, at a rate equal to the
Federal Funds Rate plus 0.50%. The "Reduction to custodian expenses" line item,
if applicable, represents earnings on cash balances maintained by the Fund
during the period. Such interest expense and other custodian fees may be paid
with these earnings.

- --------------------------------------------------------------------------------
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.

- --------------------------------------------------------------------------------
INDEMNIFICATIONS. The Fund's organizational documents provide current and former
trustees and officers with a limited indemnification against liabilities arising
in connection with the performance of their duties to the Fund. In the normal
course of business, the Fund may also enter into contracts that provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown as this would be dependent on future claims that may be made against the
Fund. The risk of material loss from such claims is considered remote.

- --------------------------------------------------------------------------------
OTHER. The preparation of financial statements in conformity with U.S. 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.

payment from the Fund of all or a portion of the service fee and/or asset-based
sales charge in respect to shares sold prior to the effective date of such
termination. The Distributor's aggregate uncompensated expenses under the plan

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


                    50 | OPPENHEIMER DEVELOPING MARKETS FUND


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 gains or losses. Such realized gains and losses are
reported with all other foreign currency gains and losses in the Statement of
Operations.

As of August 31, 2006, the Fund had outstanding foreign currency contracts as
follows:

6. ILLIQUID OR RESTRICTED SECURITIES AND CURRENCY

As of August 31, 2006, investments in securities included issues that are
illiquid or restricted. Restricted securities are 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 also 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 will not invest 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 limitation.
Securities that are illiquid or restricted are marked with the applicable
footnote on the Statement of Investments. Information concerning restricted
currency is as follows:

7. RECENT ACCOUNTING PRONOUNCEMENT

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an
enterprise's financial statements in accordance with FASB Statement No. 109,
ACCOUNTING FOR INCOME TAXES. FIN 48 requires

the evaluation of tax positions taken in the course of preparing the Fund's tax
returns to determine whether it is "more-likely-than-not" that tax positions
taken in the Fund's tax return will be ultimately sustained. A tax liability and
expense must be recorded in respect of any tax position that, in Management's
judgment, will not be fully realized. FIN 48 is effective for fiscal years
beginning after December 15, 2006. As of August 31, 2006, the Manager is
evaluating the implications of FIN 48. Its impact in the Fund's financial
statements has not yet been determined.

8. LITIGATION

A consolidated amended complaint was filed as a putative class action against
the Manager and the Transfer Agent and other defendants (including 51 of the
Oppenheimer funds including the Fund) in the U.S. District Court for the
Southern District of New York on January 10, 2005 and was amended on March 4,
2005. The complaint alleged, among other things, that the Manager charged
excessive fees for distribution and other costs, and that by permitting and/or
participating in those actions, the Directors/Trustees and the Officers of the
funds breached their fiduciary duties to fund shareholders under the Investment
Company Act of 1940 and at common law. The plaintiffs sought unspecified
damages, an accounting of all fees paid, and an award of attorneys' fees and
litigation expenses.

      In response to the defendants' motions to dismiss the suit, seven of the
eight counts in the complaint, including the claims against certain of the
Oppenheimer funds, as nominal defendants, and against certain present and former
Directors, Trustees and Officers of the funds, and the Distributor, as
defendants, were dismissed with prejudice, by court order dated March 10, 2006,
and the remaining count against the Manager and the Transfer Agent was dismissed
with prejudice by court order dated April 5, 2006. The plaintiffs filed an
appeal of those dismissals on May 11, 2006.

      The Manager believes that the allegations contained in the complaint are
without merit and that there are substantial grounds to sustain the district
court's rulings. The Manager also believes that it is premature to render any
opinion as to the likelihood of an outcome unfavorable to it, the funds, the
Directors/Trustees or the Officers on the appeal of the decisions of the
district court, and that no estimate can yet be made with any degree of
certainty as to the amount or range of any potential loss.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
THE BOARD OF TRUSTEES AND SHAREHOLDERS OF OPPENHEIMER DEVELOPING MARKETS FUND:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer Developing Markets Fund, including the statement of investments, as
of August 31, 2006, 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 five-year period then ended. 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 the standards of the Public
Company Accounting Oversight Board (United States). 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, 2006, 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, 2006, 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 five-year period then ended, in conformity with U.S.
generally accepted accounting principles.

FEDERAL INCOME TAX INFORMATION  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
In early 2007, if applicable, shareholders of record will receive information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2006. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

      Capital gain distributions of $0.7529 per share were paid to Class A,
Class B, Class C, Class N and Class Y shareholders, respectively, on December 9,
2005. Whether received in stock or in cash, the capital gain distribution should
be treated by shareholders as a gain from the sale of the capital assets held
for more than one year (long-term capital gains).

      None of the dividends paid by the Fund during the fiscal year ended August
31, 2006 are eligible for the corporate dividend-received deduction.

      A portion, if any, of the dividends paid by the Fund during the fiscal
year ended August 31, 2006 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. $161,061,222 of the Fund's fiscal year taxable income may be
eligible for the lower individual income tax rates. In early 2007, shareholders
of record will receive information regarding the percentage of distributions
that are eligible for lower individual income tax rates.

      The Fund has elected the application of Section 853 of the Internal
Revenue Code to permit shareholders to take a federal income tax credit or
deduction, at their option, on a per share basis for an aggregate amount of
$25,091,542 of foreign income taxes paid by the Fund during the fiscal year
ended August 31, 2006. A separate notice will be mailed to each shareholder,
which will reflect the proportionate share of such foreign taxes which must be
treated by shareholders as gross income for federal income tax purposes.

      Gross income of $138,895,000 was derived from sources within foreign
countries or possessions of the United States.

      Recent tax legislation allows a regulated investment company to designate
distributions not designated as capital gain distributions, as either interest
related dividends or short-term capital gain dividends, both of which are exempt
from the U.S. withholding tax applicable to non U.S. taxpayers. For the fiscal
year ended August 31, 2006, $4,820,091 or 6.10% of the ordinary distributions
paid by the Fund qualifies as an interest related dividend and $258,436,914 or
100% of the short-term capital gain distribution paid by the Fund qualifies as a
short-term capital gain dividend.

      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.

ITEM 2. CODE OF ETHICS.

The registrant has adopted a code of ethics that applies to the registrant's
principal executive officer, principal financial officer, principal accounting
officer or controller or persons performing similar functions.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The Board of Trustees of the registrant has determined that the registrant does
not have an audit committee financial expert serving on its Audit Committee. In
this regard, no member of the Audit Committee was identified as having all of
the technical attributes identified in Instruction 2(b) to Item 3 of Form N-CSR
to qualify as an "audit committee



financial expert," whether through the type of specialized education or
experience described in that Instruction. The Board has concluded that while the
members of the Audit Committee collectively have the necessary attributes and
experience required to serve effectively as an Audit Committee, no single member
possesses all of the required technical attributes through the particular

with respect to its trustees.

(e)   (1) During its regularly scheduled periodic meetings, the registrant's
      audit committee will pre-approve all audit, audit-related, tax and other
      services to be provided by the principal accountants of the registrant.

      The audit committee has delegated pre-approval authority to its Chairman
      for any subsequent new engagements that arise between regularly scheduled
      meeting dates provided that any fees such pre-approved are presented to
      the audit committee at its next regularly scheduled meeting.

      Under applicable laws, pre-approval of non-audit services maybe waived
      provided that: 1) the aggregate amount of all such services provided
      constitutes no more than five percent of the total amount of fees paid by
      the registrant to it principal accountant during the fiscal year in which
      services are provided 2) such services were not recognized by the

      non-audit fees. Those billings did not include any prohibited non-audit
      services as defined by the Securities Exchange Act of 1934.

(h)   The registrant's audit committee of the board of trustees has considered
      whether the provision of non-audit services that were rendered to the
      registrant's investment adviser, and any entity controlling, controlled
      by, or under common control with the investment adviser that provides
      ongoing services to the registrant that were not pre-approved pursuant to
      paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with
      maintaining the principal accountant's independence.

THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.    The Fund's Governance Committee (the "Committee") will evaluate potential
      Board candidates to assess their qualifications. The Committee shall have
      the authority, upon approval of the Board, to retain an executive search
      firm to assist in this effort. The Committee may consider recommendations
      by business and personal contacts of current Board members and by
      executive search firms which the Committee may engage from time to time
      and may also consider shareholder recommendations. The Committee may
      consider the advice and recommendation of the Funds' investment manager
      and its affiliates in making the selection.

2.    The Committee shall screen candidates for Board membership. The Committee
      has not established specific qualifications that it believes must be met
      by a trustee nominee. In evaluating trustee nominees, the Committee
      considers, among other things, an individual's background, skills, and
      experience; whether the individual is an "interested person" as defined in
      the Investment Company Act of 1940; and



      whether the individual would be deemed an "audit committee financial
      expert" within the meaning of applicable SEC rules. The Committee also
      considers whether the individual's background, skills, and experience will
      complement the background, skills, and experience of other nominees and
      will contribute to the Board. There are no differences in the manner in
      which the Committee evaluates nominees for trustees based on whether the
      nominee is recommended by a shareholder.

3.    The Committee may consider nominations from shareholders for the Board at
      such times as the Committee meets to consider new nominees for the Board.
      The Committee shall have the sole discretion to determine the candidates
      to present to the Board and, in such cases where required, to
      shareholders. Recommendations for trustee nominees should, at a minimum,
      be accompanied by the following:

      o     the name, address, and business, educational, and/or other pertinent
            background of the person being recommended;

      o     a statement concerning whether the person is an "interested person"
            as defined in the Investment Company Act of 1940;

      o     any other information that the Funds would be required to include in
            a proxy statement concerning the person if he or she was nominated;
            and

      o     the name and address of the person submitting the recommendation
            and, if that person is a shareholder, the period for which that
            person held Fund shares.

      The recommendation also can include any additional information which the
      person submitting it believes would assist the Committee in evaluating the
      recommendation.

4.    Shareholders should note that a person who owns securities issued by
      Massachusetts Mutual Life Insurance Company (the parent company of the
      Funds' investment adviser) would be deemed an "interested person" under
      the Investment Company Act of 1940. In addition, certain other
      relationships with Massachusetts Mutual Life Insurance Company or its
      subsidiaries, with registered broker-dealers, or with the Funds' outside
      legal counsel may cause a person to be deemed an "interested person."

5.    Before the Committee decides to nominate an individual as a trustee,
      Committee members and other directors customarily interview the individual
      in person. In addition, the individual customarily is asked to complete a
      detailed questionnaire which is designed to elicit information which must
      be disclosed under SEC and stock exchange rules and to determine whether
      the individual is subject to any statutory disqualification from serving
      as a trustee of a registered investment company.

ITEM 11. CONTROLS AND PROCEDURES.



Based on their evaluation of the registrant's disclosure controls and procedures
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of 08/31/2006, the registrant's principal executive officer and
principal financial officer found the registrant's disclosure controls and
procedures to provide reasonable assurances that information required to be
disclosed by the registrant in the reports that it files under the Securities
Exchange Act of 1934 (a) is accumulated and communicated to registrant's
management, including its principal executive officer and principal financial
officer, to allow timely decisions regarding required disclosure, and (b) is
recorded, processed, summarized and reported, within the time periods specified
in the rules and forms adopted by the U.S. Securities and Exchange Commission.

There have been no changes in the registrant's internal controls over financial
reporting that occurred during the registrant's second fiscal quarter of the
period covered by this report that have materially affected, or are reasonably
likely to materially affect, the registrant's internal control over financial
reporting.
