NOTES
- --------------------------------------------------------------------------------

      Total returns include changes in share price and reinvestment of dividends
      and capital gains distributions in a hypothetical investment for the
      periods shown. Cumulative total returns are not annualized. 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 WWW.OPPENHEIMERFUNDS.COM. READ THE PROSPECTUS
      CAREFULLY BEFORE INVESTING.

      The Fund's investment strategy and focus can change over time. The mention
      of specific Fund holdings does not constitute a recommendation by
      OppenheimerFunds, Inc.

      CLASS A shares of the Fund were first publicly offered on 4/15/88. Unless
      otherwise noted, Class A returns include the current maximum initial sales
      charge of 4.75%.

      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 10-year
      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 7/11/95. Unless
      otherwise noted, Class C returns include the contingent deferred sales

      CLASS Y shares of the Fund were first publicly offered on 4/27/98. Class Y
      shares are offered only to certain institutional investors under a special
      agreement with the Distributor, and to present or former officers,
      directors, trustees or employees (and their eligible family members) of
      the Fund, the Manager, its affiliates, its parent company and the
      subsidiaries of its parent company, and retirement plans established for
      the benefit of such individuals.

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

                         12 | OPPENHEIMER CORE BOND FUND



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 applicable); 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 June
      30, 2008.

      ACTUAL EXPENSES. The first section of the table provides information about
      actual account values and actual expenses. You may use the information in
      this section 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 first section 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 second section of the
      table provides 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 for each
      class before expenses, which is not the 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), or a $12.00 fee
      imposed annually on accounts valued at less than $500.00 (subject to
      exceptions described in

      the Statement of Additional Information). Therefore, the "hypothetical"
      section of the table is 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.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 182/366
(to reflect the one-half year period). Those annualized expense ratios,
excluding indirect expenses from affiliated fund, based on the 6-month period
ended June 30, 2008 are as follows:



CLASS              EXPENSE RATIOS
- -----------------------------------
                
Class A                 0.87%

Class Y                 0.48


The expense ratios reflect reduction to custodian expenses and voluntary waivers
or reimbursements of expenses by the Fund's Manager 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 and reduction to
custodian expenses, if applicable.

FOOTNOTES TO STATEMENT OF INVESTMENTS

1. Represents the current interest rate for a variable or increasing rate
security.

2. Illiquid security. The aggregate value of illiquid securities as of June
30, 2008 was $51,312,546, which represents 2.16% of the Fund's net assets. See
Note 7 of accompanying Notes.

3. Interest-Only Strips represent the right to receive the monthly interest
payments on an underlying pool of mortgage loans. These securities typically
decline in price as interest rates decline. Most other fixed income securities
increase in price when interest rates decline. The principal amount of the
underlying pool represents the notional amount on which current interest is
calculated. The price of these securities is typically more sensitive to changes
in prepayment rates than traditional mortgage-backed securities (for example,
GNMA pass-throughs). Interest rates disclosed represent current yields based
upon the current cost basis and estimated timing and amount of future cash
flows. These securities amount to $76,501,303 or 3.23% of the Fund's net assets
as of June 30, 2008.

4. Principal-Only Strips represent the right to receive the monthly principal
payments on an underlying pool of mortgage loans. The value of these securities
generally increases as interest rates decline and prepayment rates rise. The
price of these securities is typically more volatile than that of coupon-bearing
bonds of the same maturity. Interest rates disclosed represent current yields
based upon the current cost basis and estimated timing of future cash flows.
These securities amount to $1,385,414 or 0.06% of the Fund's net assets as of
June 30, 2008.

5. When-issued security or delayed delivery to be delivered and settled after
June 30, 2008. See Note 1 of accompanying Notes.

6. All or a portion of the security is held in collateralized accounts to
cover initial margin requirements on open futures contracts. The aggregate
market value of such securities is $5,069,311. See Note 5 of accompanying Notes.

7. Zero coupon bond reflects effective yield on the date of purchase.

8. 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 $74,919,511 or 3.16% of the Fund's net
assets as of June 30, 2008.

9. Partial or fully-loaned security. See Note 8 of accompanying Notes.

VALUATION INPUTS
- --------------------------------------------------------------------------------

Various data inputs are used in determining the value of each of the Fund's
investments as of the reporting period end. These data inputs are categorized in
the following hierarchy under applicable financial accounting standards:

      1)  Level 1 - quoted prices in active markets for identical assets or
          liabilities (including securities actively traded on a securities
          exchange)

      2)  Level 2 - inputs other than quoted prices that are observable for
          the asset (such as quoted prices for similar assets and
          market-corroborated inputs such as interest rates, prepayment
          speeds, credit risks, etc.)

      3)  Level 3 - unobservable inputs (including the Manager's own judgments
          about assumptions that market participants would use in pricing the
          asset).

The market value of the Fund's investments was determined based on the following
inputs as of June 30, 2008:



                                                                        INVESTMENTS   OTHER FINANCIAL

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Core Bond Fund (the "Fund"), is a separate fund of Oppenheimer
Integrity Funds, an open-end management investment company registered under the
Investment Company Act of 1940, as amended. The Fund's investment objective is
to seek total return by investing mainly in debt instruments. The Fund's
investment adviser 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 72
months after the date of purchase.

     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 trading.

     Effective for fiscal periods beginning after November 15, 2007, FASB
Statement of Financial Accounting Standards No. 157, Fair Value Measurements,
establishes a hierarchy for measuring fair value of assets and liabilities. As
required by the standard, each investment asset or liability of the Fund is
assigned a level at measurement date based on the significance and source of the
inputs to its valuation. Quoted prices in active markets for identical
securities are classified as "Level 1", inputs other than quoted prices for an
asset that are observable are classified as "Level 2" and unobservable inputs,
including the Manager's judgment about the assumptions that a market participant
would use in pricing an asset or liability are classified as "Level 3". The
inputs used for valuing securities are not necessarily an indication of the
risks associated with investing in those securities. A table summarizing the
Fund's investments under these levels of classification is included following
the Statement of Investments.

     Securities are valued using quoted market prices, when available, as
supplied primarily either by portfolio pricing services approved by the Board of
Trustees or dealers. These securities are typically classified within Level 1 or
2; however, they may be designated as

                        F43 | OPPENHEIMER CORE BOND FUND



NOTE TO FINANCIAL STATEMENTS Unaudited / Continued

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES Continued

Level 3 if the dealer or portfolio pricing service values a security through an
internal model with significant unobservable market data inputs.

     Securities traded on a registered U.S. securities exchange are valued based
on the last sale price of the security reported on the principal exchange on
which traded, prior to the time when the Fund's assets are valued. Securities
whose principal exchange is NASDAQ(R) are valued based on the official closing
prices reported 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 current day's closing "bid"
and "asked" prices, and if not, at the current day's closing bid price. A
foreign security traded on a foreign exchange is valued based on the last sale
price on the principal exchange on which the security is traded, as identified
by the portfolio pricing service used by the Manager, prior to the time when the
Fund's assets are valued. In the absence of a sale, the security is valued at
the most recent official closing price on the principal exchange on which it is
traded.

     Shares of a registered investment company that are not traded on an
exchange are valued at that investment company's net asset value per share.

     Corporate, government and municipal debt instruments having a remaining
maturity in excess of sixty days and all mortgage-backed securities,
collateralized mortgage obligations and other asset-backed securities are valued
at the mean between the "bid" and "asked" prices.

     "Money market-type" debt instruments with remaining maturities of sixty
days or less are valued at cost adjusted by the amortization of discount or
premium to maturity (amortized cost), which approximates market value. These
securities are typically designated as Level 2.

     In the absence of a readily available quoted market price, including for
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 the securities' respective exchanges, the Manager, acting
through its internal valuation committee, in good faith determines the fair
valuation of that asset using consistently applied procedures under the
supervision of the Board of Trustees (which reviews those fair valuations by the
Manager). Those procedures include certain standardized methodologies to fair
value securities. Such methodologies include, but are not limited to, pricing
securities initially at cost and subsequently adjusting the value based on:
changes in company specific fundamentals, changes in an appropriate securities
index, or changes in the value of similar securities which may be adjusted for
any discounts related to resale restrictions. When possible, such methodologies
use observable market inputs such as quoted prices of similar securities,
observable interest rates, currency rates and yield curves. The methodologies
used for valuing securities are not necessarily an indication of the risks
associated with investing in those securities.

                        F44 | OPPENHEIMER CORE BOND FUND



     Fair valued securities may be classified as "Level 3" if the valuation
primarily reflects the Manager's own assumptions about the inputs that market
participants would use in valuing such securities.

     There have been no significant changes to the fair valuation methodologies
during the period.

- --------------------------------------------------------------------------------
SECURITIES ON A WHEN-ISSUED OR DELAYED DELIVERY BASIS. The Fund may purchase
securities on a "when-issued" basis, and may purchase or sell securities on a
"delayed delivery" basis. "When-issued" or "delayed delivery" refers to
securities whose terms and indenture are available and for which a market
exists, but which are not available for immediate delivery. Delivery and payment
for securities that have been purchased by the Fund on a when-issued basis
normally takes place within six months and possibly as long as two years or more
after the trade date. During this period, such securities do not earn interest,
are subject to market fluctuation and may increase or decrease in value prior to
their delivery. The purchase of securities on a when-issued basis may increase
the volatility of the Fund's net asset value to the extent the Fund executes
such transactions while remaining substantially fully invested. When the Fund
engages in when-issued or delayed delivery transactions, it relies on the buyer
or seller, as the case may be, to complete the transaction. Their failure to do
so may cause the Fund to lose the opportunity to obtain or dispose of the
security at a price and yield it considers advantageous. The Fund maintains
internally designated assets with a market value equal to or greater than the
amount of its purchase commitments. The Fund may also sell securities that it
purchased on a when-issued basis or forward commitment prior to settlement of
the original purchase.

As of June 30, 2008, the Fund had purchased securities issued on a when-issued
or delayed delivery basis and sold securities issued on a delayed delivery basis
as follows:

        
        
                                        WHEN-ISSUED OR DELAYED DELIVERY
                                                     BASIS TRANSACTIONS
        ---------------------------------------------------------------
                                     
        Purchased securities                               $423,065,384
        

The Fund may enter into "forward roll" transactions with respect to
mortgage-related securities. In this type of transaction, the Fund sells a
mortgage-related security to a buyer and simultaneously agrees to repurchase a
similar security (same type, coupon and maturity) at a later date at a set
price. During the period between the sale and the repurchase, the Fund will not
be entitled to receive interest and principal payments on the securities that
have been sold. The Fund records the incremental difference between the forward
purchase and sale of each forward roll as realized gain (loss) on investments or
as fee income in the case of such transactions that have an associated fee in
lieu of a difference in the forward purchase and sale price.

     Risks of entering into forward roll transactions include the potential
inability of the counterparty to meet the terms of the agreement; the potential
of the Fund to receive inferior securities at redelivery as compared to the
securities sold to the counterparty; counterparty credit risk. To assure its
future payment of the purchase price, the Fund

maintains internally designated assets with a market value equal to or greater
than the payment obligation under the roll.

- --------------------------------------------------------------------------------
CREDIT RISK. The Fund invests in high-yield, non-investment-grade bonds, which
may be subject to a greater degree of credit risk. Credit risk relates to the
ability of the issuer to meet interest or principal payments or both as they
become due. The Fund may acquire securities in default, and is not obligated to
dispose of securities whose issuers subsequently default. As of June 30, 2008,
securities with an aggregate market value of $2, representing less than .01% of
the Fund's net assets, were in default.

- --------------------------------------------------------------------------------
INVESTMENT IN OPPENHEIMER INSTITUTIONAL MONEY MARKET FUND. The Fund is permitted
to invest daily available cash balances in an affiliated money market fund. The
Fund may invest the available cash in Class E shares of Oppenheimer
Institutional Money Market Fund ("IMMF") to seek current income while preserving
liquidity. IMMF is a registered open-end management investment company,
regulated as a money market fund under the Investment Company Act of 1940, as
amended. The Manager is also the investment adviser of IMMF. The Fund's
investment in IMMF is included in the Statement of Investments. As a
shareholder, the Fund is subject to its proportional share of IMMF's Class E
expenses, including its management fee. The Manager will waive fees and/or
reimburse Fund expenses in an amount equal to the indirect management fees
incurred through the Fund's investment in IMMF.

- --------------------------------------------------------------------------------
REPURCHASE AGREEMENTS. The Fund requires its custodian bank 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 collateral is required to be
sufficient to cover payments of interest and principal. 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.

- --------------------------------------------------------------------------------
INVESTMENTS WITH OFF-BALANCE SHEET MARKET RISK. The Fund enters into financial
instrument transactions (such as swaps, futures, options and other derivatives)
that may have off-balance sheet market risk. Off-balance sheet market risk
exists when the maximum potential loss on a particular financial instrument is
greater than the value of such financial instrument, as reflected in the Fund's
Statement of Assets and Liabilities.

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

                        F46 | OPPENHEIMER CORE BOND FUND


- --------------------------------------------------------------------------------
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 Fund files income tax returns in U.S. federal and applicable state
jurisdictions. The statute of limitations on the Fund's tax return filings
generally remain open for the three preceding fiscal reporting period ends.

During the fiscal year ended December 31, 2007, the Fund did not utilize any
capital loss carryforward to offset capital gains realized in that fiscal year.
As of December 31, 2007, the Fund had available for federal income tax purposes
straddle losses of $260,082 and unused capital loss carryforwards as follows:

As of June 30, 2008, the Fund had available for federal income tax purposes an
estimated capital loss carryforward of $9,736,980. This estimated capital loss
carryforward represents carryforward as of the end of the last fiscal year,
increased for losses deferred under tax accounting rules to the current fiscal
year and is increased or decreased by capital losses or gains realized in the
first six months of the current fiscal year. During the six months ended June
30, 2008, it is estimated that the Fund will utilize $5,787,253 of capital loss
carryforward to offset realized capital gains.

     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.

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 June 30, 2008 are noted in the following
table. The primary difference between book and tax appreciation or depreciation
of securities and other investments, if applicable, is attributable to the tax
deferral of losses or tax realization of financial statement unrealized gain or
loss.

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Board of Trustees has adopted a compensation
deferral 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 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 compensation deferral plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations and
may differ from U.S. generally accepted accounting principles, are recorded on
the ex-dividend date. Income distributions, if any, are declared daily and paid
monthly. 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 is recognized on an accrual basis. Discount and
premium, which are included in interest income on the Statement of Operations,
are amortized or accreted daily.

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

                        F48 | OPPENHEIMER CORE BOND FUND


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 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 increases and
decreases in net assets from operations during the reporting period. Actual
results could differ from those estimates.

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEES. Under the investment advisory agreement, the Fund pays the
Manager a management fee based on the daily net assets of the Fund at an annual
rate as shown in the following table:

        
        
        FEE SCHEDULE
        ---------------------------------------------
                                             
        Up to $1 billion                        0.50%
        Over $1 billion                         0.35
        

- -------------------------------------------------------------------------------
ADMINISTRATION SERVICE FEES. The Fund pays the Manager a fee of $1,500 per year
for preparing and filing the Fund's tax returns.

- -------------------------------------------------------------------------------
TRANSFER AGENT FEES. OppenheimerFunds Services ("OFS"), a division of the
Manager, acts as the transfer and shareholder servicing agent for the Fund. The
Fund pays OFS a per account fee. For the six months ended June 30, 2008, the
Fund paid $1,570,998 to OFS for services to the Fund.

                        F50 | OPPENHEIMER CORE BOND FUND


     Additionally, Class Y shares are subject to minimum fees of $10,000
annually for assets of $10 million or more. The Class Y shares are subject to
the minimum fees in the event that the per account fee does not equal or exceed
the applicable minimum fees. OFS may voluntarily waive the minimum fees.

- -------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLAN (12b-1) FEES. Under its General Distributor's
Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the "Distributor")
acts as the Fund's principal underwriter in the continuous public offering of
the Fund's classes of shares.

- -------------------------------------------------------------------------------
SERVICE PLAN FOR CLASS A SHARES. The Fund has adopted a Service Plan (the
"Plan") for Class A shares under Rule 12b-1 of the Investment Company Act of
1940. Under the Plan, the Fund reimburses the Distributor for a portion of its
costs incurred for services provided to accounts that hold Class A shares.
Reimbursement is made periodically at an annual rate of up to 0.25% of the
average annual net assets of Class A shares of the Fund. The Distributor
currently uses all of those fees to pay dealers, brokers, banks and other
financial institutions periodically for providing personal service and
maintenance of accounts of their customers that hold Class A shares. Any
unreimbursed expenses the Distributor incurs with respect to Class A shares in
any fiscal year cannot be recovered in subsequent periods. Fees incurred by the
Fund under the Plan are detailed in the Statement of Operations.

- -------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund
has adopted Distribution and Service Plans (the "Plans") for Class B, Class C
and Class N shares under Rule 12b-1 of the Investment Company Act of 1940 to
compensate the Distributor for its services in connection with the distribution
of those shares and servicing accounts. Under the Plans, the Fund pays the
Distributor an annual asset-based sales charge of 0.75% on Class B and Class C
shares and 0.25% on Class N shares. The Distributor also receives a service fee
of 0.25% per year under each plan. If either the Class B, Class C or Class N
plan is terminated by the Fund or by the shareholders of a class, the Board of
Trustees and its independent trustees must determine whether the Distributor
shall be entitled to 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 Plans at June 30, 2008 for Class B, Class C and Class N
shares were $1,925,856, $3,134,879, $1,399,831, respectively. Fees incurred by
the Fund under the Plans are detailed in the Statement of Operations.

- -------------------------------------------------------------------------------
SALES CHARGES. Front-end sales charges and contingent deferred sales charges
("CDSC") do not represent expenses of the Fund. They are deducted from the
proceeds of sales of Fund shares prior to investment or from redemption proceeds
prior to remittance, as applicable. The sales charges retained by the
Distributor from the sale of shares and the CDSC retained by the Distributor on
the redemption of shares is shown in the following table for the period
indicated.

- --------------------------------------------------------------------------------
WAIVERS AND REIMBURSEMENTS OF EXPENSES. Effective March 1, 2004, the Manager has
voluntarily undertaken to limit the "Total Expenses" for all classes of shares
so that "Total expenses after waivers, payments and/or reimbursements and
reduction to custodian expenses" as percentages of average daily net assets,
will not exceed the following annual rates: 0.90% for the Class A shares; 1.65%
for the Class B and Class C shares, respectively; 1.15% for the Class N shares
and 0.65% for the Class Y shares. During the six months ended June 30, 2008, the
Manager reimbursed the Fund $64,567 and $35,917 for Class B and Class N shares,
respectively. The Manager may terminate this voluntary expense limitation
arrangement at any time without notice to shareholders.

     OFS has voluntarily agreed to limit transfer and shareholder servicing
agent fees for all classes to 0.35% of average annual net assets per class. This
undertaking may be amended or withdrawn at any time.

     The Manager will waive fees and/or reimburse Fund expenses in an amount
equal to the indirect management fees incurred through the Fund's investment in
IMMF. During the six months ended June 30, 2008, the Manager waived $34,554 for
IMMF management fees.

- -------------------------------------------------------------------------------
5. FUTURES CONTRACTS

A futures contract is a commitment to buy or sell a specific amount of a
financial instrument at a negotiated price on a stipulated future date. The Fund
may buy and sell futures contracts and may also buy or write put or call options
on these futures contracts.

     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.

     Upon entering into a futures contract, the Fund is required to deposit
either cash or securities (initial margin) in an amount equal to a certain
percentage of the contract value. Subsequent payments (variation margin) are
made or received by the Fund each day. The variation margin payments are equal
to the daily changes in the contract value and are recorded as unrealized gains
and losses.

     Futures contracts are reported on a schedule following the Statement of
Investments. Securities held in collateralized accounts to cover initial margin
requirements on open futures contracts are noted in the Statement of
Investments. Cash held by the broker to cover initial margin requirements on
open futures contracts and the receivable and/or

                        F52 | OPPENHEIMER CORE BOND FUND


payable for the daily mark to market for the variation margin are noted in the
Statement of Assets and Liabilities. The net change in unrealized appreciation
and depreciation is reported in the Statement of Operations. Realized gains
(losses) are reported in the Statement of Operations at the closing or
expiration of futures contracts.

     Risks of entering into futures contracts (and related options) include the
possibility that there may be an illiquid market where the Fund is unable to
liquidate the contract or enter into an offsetting position and, if used for
hedging purposes, the risk that the price of the contract will correlate
imperfectly with the prices of the Fund's securities.

- -------------------------------------------------------------------------------
6. SWAP  CONTRACTS

The Fund may enter into swap contract agreements with a counterparty to exchange
a series of cash flows based on either specified reference rates, or the
occurrence of a credit event, over a specified period. Such contracts may
include interest rate, equity, debt, index, total return, credit and currency
swaps.

     Swaps are marked to market daily using primarily quotations from pricing
services, counterparties and brokers. Swap contracts are reported on a schedule
following the Statement of Investments. The value of the contracts is separately
disclosed on the Statement of Assets and Liabilities. The unrealized
appreciation (depreciation) related to the change in the valuation of the
notional amount of the swap is combined with the accrued interest due to (owed
by) the Fund at termination or settlement. The net change in this amount during
the period is included on the Statement of Operations. The Fund also records any
periodic payments received from (paid to) the counterparty, including at
termination, under such contracts as realized gain (loss) on the Statement of
Operations.

     Risks of entering into swap contracts include credit, market and liquidity
risk. Credit risk arises from the possibility that the counterparty will
default. If the counterparty defaults, the Fund's loss will consist of the net
amount of contractual payments that the Fund has not yet received. Market risk
is the risk that the value of the contract will depreciate due to unfavorable
changes in the reference asset. If there is an illiquid market for the
agreement, the Fund may be unable to close the contract prior to contract
termination.

- -------------------------------------------------------------------------------
CREDIT DEFAULT SWAP CONTRACTS. A credit default swap is a bilateral contract
that enables an investor to buy or sell protection against a defined-issuer
credit event. The Fund may enter into credit default swaps on a single security,
or a basket of securities.

     In a credit default swap contract, the purchaser of the contract will pay a
periodic interest fee, similar to an insurance premium, on the notional amount
of the swap contract to the counterparty (the seller of the contract). If there
is a credit event (for example, bankruptcy or a failure to timely pay interest
or principal), the purchaser will exercise the contract and will receive a
payment from the seller of the contract equal to the notional value of the
credit default swap contract less the value of the underlying security. In the
event that the credit default swap is exercised due to a credit event, the

NOTE TO FINANCIAL STATEMENTS Unaudited / Continued
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
6. SWAP CONTRACTS Continued

difference between the value of the underlying security and the notional amount
is recorded as realized gain (loss) and is included on the Statement of
Operations.

     Risks of credit default swaps include, but are not limited to, the cost of
paying for credit protection if there are no credit events, or the cost of
selling protection (paying the notional amount) when a credit event occurs,
pricing transparency when assessing the cost of a credit default swap, and the
need to fund the delivery obligation (either cash or defaulted securities).

- --------------------------------------------------------------------------------
INTEREST RATE SWAP CONTRACTS. An interest rate swap is an agreement between
counter-parties to exchange periodic interest payments on the notional amount of
the contract. One cash flow stream will typically be a floating rate payment
based upon a specified index while the other is typically a fixed rate.

     Interest rate swap agreements include interest rate risk. There is a risk,
based on future movements of interest rates where the payments made by the Fund
under a swap agreement will be greater than the payments it received.

- --------------------------------------------------------------------------------
TOTAL RETURN SWAP CONTRACTS. A total return swap is an agreement between
counter-parties to exchange a set of future cash flows on the notional amount of
the contract. One cash flow is typically based on a reference interest rate or
index and the other on the total return of a reference asset such as a security,
a basket of securities, or an index. The total return includes appreciation or
depreciation on the reference asset, plus any interest or dividend payments.

- --------------------------------------------------------------------------------
7. ILLIQUID  SECURITIES

As of June 30, 2008, investments in securities included issues that are
illiquid. Investments may be illiquid because they do not have an active trading
market, making it difficult to value them or dispose of them promptly at an
acceptable price. The Fund will not invest more than 15% of its net assets
(determined at the time of purchase and reviewed periodically) in illiquid
securities. Securities that are illiquid are marked with an applicable footnote
on the Statement of Investments.

- --------------------------------------------------------------------------------
8. SECURITIES  LENDING

The Fund lends portfolio securities from time to time in order to earn
additional income in the form of fees or interest on securities received as
collateral or the investment of any cash received as collateral. The loans are
secured by collateral (either securities, letters of credit, or cash) in an
amount not less than 100% of the market value of the loaned securities during
the period of the loan. The market value of the loaned securities is determined
at the close of each business day and any additional required collateral is
delivered to the Fund on the next business day. If the borrower defaults on its
obligation to return the securities loaned because of insolvency or other
reasons, the Fund could experience delays and cost in recovering the securities
loaned or in gaining access to the collateral. The Fund

                        F54 | OPPENHEIMER CORE BOND FUND


continues to receive the economic benefit of interest or dividends paid on the
securities loaned in the form of a substitute payment received from the borrower
and recognizes the gain or loss in the fair value of the securities loaned that
may occur during the term of the loan. The Fund has the right under the lending
agreement to recover the securities from the borrower on demand. As of June 30,
2008, the Fund had on loan securities valued at $20,525,747. Collateral of
$21,763,265 was received for the loans, all of which was received in cash and
subsequently invested in approved instruments.

- --------------------------------------------------------------------------------
9. RECENT ACCOUNTING PRONOUNCEMENT

In March 2008, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 161, "Disclosures about
Derivative Instruments and Hedging Activities." This standard requires enhanced
disclosures about derivative and hedging activities, including qualitative
disclosures about how and why the Fund uses derivative instruments, how these
activities are accounted for, and their effect on the Fund's financial position,
financial performance and cash flows. SFAS No. 161 is effective for financial
statements issued for fiscal years beginning after November 15, 2008 and interim
periods within those fiscal years. At this time, management is evaluating the
implications of SFAS No. 161 and its impact on the Fund's financial statements
and related disclosures.

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:

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

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

      -     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

      -     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 06/30/2008, 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.
