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%.

CLASS B shares of the Fund were first publicly offered on 5/3/93. Unless
otherwise noted, Class B returns include the applicable contingent deferred
sales charge of 5% (1-year) and 2% (5-year). Because Class B shares convert to
Class A shares 72 months after purchase, the 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 charge of
1% for the 1-year period. Class C shares are subject to an annual 0.75%
asset-based sales charge.

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


                         12 | OPPENHEIMER CORE BOND FUND



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 special

                         13 | 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 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 June 30, 2007.

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), 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" 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.

Class Y Hypothetical               1,000.00      1,022.36      2.46

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 181/365
(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, 2007 are as follows:

CLASS          EXPENSE RATIOS
- -----------------------------
Class A             0.87%
- -----------------------------
Class B             1.64
- -----------------------------
Class C             1.64
- -----------------------------
Class N             1.14
- -----------------------------
Class Y             0.49

The expense ratio reflects reduction to custodian fees and voluntary waiver or
reimbursement 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.

FOOTNOTES TO STATEMENT OF INVESTMENTS

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

2. 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 $56,392,609 or 3.27% of the Fund's net
assets as of June 30, 2007.

3. Illiquid security. The aggregate value of illiquid securities as of June 30,
2007 was $46,573,901, which represents 2.70% of the Fund's net assets. See Note
9 of accompanying Notes.

4. 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 $61,227,258 or 3.55% of the Fund's net assets
as of June 30, 2007.

5. 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 $2,796,573 or 0.16% of the Fund's net assets as of
June 30, 2007.

6. When-issued security or forward commitment to be delivered and settled after
June 30, 2007. See Note 1 of accompanying Notes.

7. Partial or fully-loaned security. See Note 10 of accompanying Notes.

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

9. 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 $2,141,189. See Note 6 of accompanying Notes.

10. Non-income producing security.

11. Issue is in default. See Note 1 of accompanying Notes.

12. Interest or dividend is paid-in-kind, when applicable.

13. This bond has no contractual maturity date, is not redeemable and
contractually pays an indefinite stream of interest. Rate reported represents
the current interest rate for this variable rate security.

14. Rate shown is the 7-day yield as of June 30, 2007.

15. Is or was an affiliate, as defined in the Investment Company Act of 1940, at
or during the period ended June 30, 2007, by virtue of the Fund owning at least
5% of the voting securities of the issuer or as a result of the Fund and the
issuer having the same investment advisor. Transactions during the period in
which the issuer was an affiliate are as follows:

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 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 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
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


                         42 | OPPENHEIMER CORE BOND FUND



trading session ending at, or most recently prior to, the time when the Fund's
assets are valued. Options are valued daily based upon the last sale price on
the principal exchange on which the option is traded. 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. Investments in open-end registered investment companies (including
affiliated funds) are valued at that fund's net asset value. Short-term "money
market type" debt securities with remaining maturities of sixty days or less are
valued at amortized cost (which approximates market value).

- --------------------------------------------------------------------------------
SECURITIES ON A WHEN-ISSUED BASIS OR FORWARD COMMITMENT. Delivery and payment
for securities that have been purchased by the Fund on a when-issued basis or
forward commitment take place generally at least ten days or more after the
trade date. Normally the settlement date occurs within six months after the
trade date; however, the Fund may, from time to time, purchase securities whose
settlement date extends six months or more beyond 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 Fund
maintains internally designated assets with a market value equal to or greater
than the amount of its purchase commitments. The purchase of securities on a
when-issued basis or forward commitment may increase the volatility of the
Fund's net asset value to the extent the Fund executes such transactions while
remaining substantially fully invested. 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, 2007, the Fund had purchased $423,979,102
of securities issued on a when-issued basis or forward commitment and sold
$107,700,182 of securities issued on a when-issued basis or forward commitment.

      In connection with its ability to purchase or sell securities on a
when-issued basis, the Fund may enter into forward roll transactions with
respect to mortgage-related securities. Forward roll transactions require the
sale of securities for delivery in the current month, and a simultaneous
agreement with the same counterparty to repurchase similar (same type, coupon
and maturity) but not identical securities on a specified future date. 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; and the potential
pay down speed variance between the mortgage-related pools.

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

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.

- --------------------------------------------------------------------------------
SECURITY CREDIT RISK. The Fund invests in high-yield securities, which may be
subject to a greater degree of credit risk, market fluctuations and loss of
income and principal, and may be more sensitive to economic conditions than
lower-yielding, higher-rated fixed-income securities. The Fund may acquire
securities in default, and is not obligated to dispose of securities whose
issuers subsequently default. As of June 30, 2007, securities with an aggregate
market value of $2, representing less than 0.005% 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") which seeks current income and
stability of principal. 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 advisor 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.


                         44 | OPPENHEIMER CORE BOND FUND



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

- --------------------------------------------------------------------------------
INVESTMENTS WITH OFF BALANCE SHEET 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.

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

      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.

      As of June 30, 2007, the Fund had available for federal income tax
purposes an estimated capital loss carryforward of $22,662,330 expiring by 2015.
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. As of June
30, 2007, it is estimated that the Fund will not utilize any capital loss
carryforward to offset realized capital gains. During the fiscal year ended
December 31, 2006, the Fund did not utilize any capital loss carryforward to
offset capital gains realized in that fiscal year.

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

- --------------------------------------------------------------------------------
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,
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, 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.


                         46 | OPPENHEIMER CORE BOND FUND



- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
Realized gains and losses on securities sold are determined on the basis of
identified cost.

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

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

$1,124,656 to OFS for services to the Fund.

      Additionally, Class Y shares are subject to minimum fees of $10,000 per
annum 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.


                         48 | OPPENHEIMER CORE BOND FUND



- --------------------------------------------------------------------------------
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 for Class A
shares. It 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 services 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 for Class B, Class C and Class N
shares 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 determines its
uncompensated expenses under the plan at calendar quarter ends. The
Distributor's aggregate uncompensated expenses under the plan at June 30, 2007
for Class B, Class C and Class N shares were $2,368,013, $2,820,813 and
$1,038,104, 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.

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

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 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, 2007, the Manager
reimbursed the Fund $513, $76,407, $16,957 and $38,721 for Class A, Class B,
Class C 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, 2007, the Manager waived $54,207 for
IMMF management fees.

- --------------------------------------------------------------------------------
5. FOREIGN CURRENCY CONTRACTS

A foreign currency contract is a commitment to purchase or sell a foreign
currency at a future date, at a negotiated rate. The Fund may enter into foreign
currency contracts to settle specific purchases or sales of securities
denominated in a foreign currency and for protection from adverse exchange rate
fluctuation. Risks to the Fund include the potential inability of the
counterparty to meet the terms of the contract.

      The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using prevailing foreign currency exchange rates.
Unrealized appreciation and depreciation on foreign currency contracts are
reported in the Statement of Assets and Liabilities as a receivable or payable
and in the Statement of Operations with the change in unrealized appreciation or
depreciation.

      The Fund may realize a gain or loss upon the closing or settlement of the
foreign transaction. Contracts closed or settled with the same broker are
recorded as net realized 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 June 30, 2007, the Fund had no outstanding foreign currency
contracts.

- --------------------------------------------------------------------------------
6. FUTURES CONTRACTS

A futures contract is a commitment to buy or sell a specific amount of a
commodity or financial instrument at a negotiated price on a stipulated future
date. Futures contracts are traded on a commodity exchange. The Fund may buy and
sell futures contracts that relate to broadly based securities indices
(financial futures) or debt securities (interest rate futures) in order to gain
exposure to or protection from changes in market value of stocks and bonds or
interest rates. The Fund may also buy or write put or call options on these
futures contracts.


                         50 | OPPENHEIMER CORE BOND FUND



      The Fund generally sells futures contracts as a hedge against increases in
interest rates and decreases in market value of portfolio securities. The Fund
may also purchase futures contracts to gain exposure to market changes as it may
be more efficient or cost effective than actually buying securities.

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

      Cash held by the broker to cover initial margin requirements on open
futures contracts is noted in the Statement of Assets and Liabilities.
Securities held in collateralized accounts to cover initial margin requirements
on open futures contracts are noted in the Statement of Investments. The
Statement of Assets and Liabilities reflects a receivable and/or payable for the
daily mark to market for variation margin. Realized gains and losses are
reported in the Statement of Operations at the closing and expiration of futures
contracts. The net change in unrealized appreciation and depreciation is
reported in the Statement of Operations.

      Risks of entering into futures contracts (and related options) include the
possibility that there may be an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.

As of June 30, 2007, the Fund had outstanding futures contracts as follows:



                                                                            UNREALIZED

7. 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 to hedge an existing position or to obtain exposure to a
security or market by purchasing or selling credit protection. The Fund may
enter into credit default swaps on a single security, or a basket of securities.


                         51 | OPPENHEIMER CORE BOND FUND



NOTES TO FINANCIAL STATEMENTS  Unaudited / Continued
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
7. CREDIT DEFAULT SWAP CONTRACTS Continued

      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.

      The periodic interest fees are accrued daily as a component of unrealized
appreciation (depreciation) and are recorded as realized gain (loss) upon
payment. In the event that the credit default swap is exercised due to a credit
event, the 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.

      Credit default swaps are marked to market daily using primarily quotations
from counter-parties and brokers. 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.

      Risks of credit default swaps include, but are not limited to, the cost of
paying for credit protection if there are no credit events, pricing transparency
when assessing the cost of a credit default swap, counterparty risk, adverse
pricing when purchasing bonds to satisfy its delivery obligation, and the need
to fund the delivery obligation (either cash or defaulted securities depending
on whether the Fund is the purchaser or seller of the credit default swap
contract, respectively).

Information regarding such credit default swaps as of June 30, 2007 is as
follows:

8. TOTAL RETURN SWAP CONTRACTS

A total return swap is an agreement under which a set of future cash flows is
exchanged between two counterparties. One cash flow stream will typically be
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. Payments under the swap are based on an
agreed upon principal amount but since this principal amount is not exchanged,
it represents neither an asset nor a liability to either counterparty, and is
referred to as notional. Total return swaps are marked to market daily using
primarily quotations from counterparties and brokers. 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 amount 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. The primary risks associated with total return swaps are credit
risks (if the counterparty fails to meet its obligations) and market risk (if
there is no liquid market for the agreement or unfavorable changes occur in the
reference asset).

As of June 30, 2007, the Fund had entered into the following total return swap
agreements:



                            NOTIONAL             PAID BY             RECEIVED BY   TERMINATION

9. ILLIQUID SECURITIES

As of June 30, 2007, investments in securities included issues that are
illiquid. A security may be considered illiquid if it lacks a readily available
market or if its valuation has not changed for a certain period of time. The
Fund 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 the applicable footnote on the Statement of
Investments.

- --------------------------------------------------------------------------------
10. SECURITIES LENDING

The Fund lends portfolio securities from time to time in order to earn
additional income. In return, the Fund receives collateral in the form of
securities, letters of credit or cash, against the loaned securities and
maintains collateral 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 business each day. If the Fund is
undercollateralized at the close of business due to an increase in market value
of securities on loan, additional collateral is requested from the borrowing
counterparty and is delivered to the Fund on the next business day. Cash
collateral may be invested in approved investments and the Fund bears the risk
of any loss in value of these investments. The Fund retains a portion of the
interest earned from the collateral. 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 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. As of June 30, 2007, the Fund had
on loan securities valued at $87,135,932, which are included in the Statement of
Assets and Liabilities as "Investments, at value" and, when applicable, as
"Receivable for Investments sold." Collateral of $88,646,614 was received for
the loans, $75,429,997 of which was received in cash and subsequently invested
in approved investments. In addition, collateral of $13,216,617 was also
received in the form of securities.

- --------------------------------------------------------------------------------
11. RECENT ACCOUNTING PRONOUNCEMENT

In September 2006, Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 157, FAIR VALUE MEASUREMENTS. This
standard establishes a single authoritative definition of fair value, sets out a
framework for measuring fair value and expands disclosures about fair value
measurements. SFAS No. 157 applies to fair value measurements already required
or permitted by existing standards. SFAS No. 157 is effective for financial
statements issued for fiscal years beginning after November 15, 2007, and
interim periods within those fiscal years. As of June 30, 2007, the Manager does
not believe the adoption of SFAS No. 157 will materially impact the financial
statement amounts; however, additional disclosures may be required about the
inputs used to develop the measurements and the effect of certain of the
measurements on changes in net assets for the period.

$122,287,022 and Class N net assets of $43,300,947 on March 23, 2006. The net

limitations. The exchange qualified as a tax-free reorganization for federal
income tax purposes.

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 06/30/2007, 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.

ITEM 12. EXHIBITS.

(a)  (1)  Not applicable to semiannual reports.

     (2)  Exhibits attached hereto.

     (3)  Not applicable.

(b)  Exhibit attached hereto.
