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.

CLASS A shares of the Fund were first publicly offered on 4/15/88. The Fund's
maximum sales charge for Class A shares was lower prior to 3/29/91, so actual
performance may have been higher. 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.

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
agreements with the Distributor.

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

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, 2005.

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


                         11 | OPPENHEIMER CORE BOND FUND


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

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          1,021.57           3.26

Hypothetical assumes 5% 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 based on
the 6-month period ended June 30, 2005 are as follows:

CLASS         EXPENSE RATIOS
- ----------------------------
Class A           0.90%
- ----------------------------
Class B           1.65
- ----------------------------
Class C           1.65
- ----------------------------
Class N           1.15
- ----------------------------
Class Y           0.65

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

FOOTNOTES TO STATEMENT OF INVESTMENTS

1. Illiquid or restricted security. The aggregate value of illiquid or
restricted securities as of June 30, 2005 was $29,405,936, which represents
3.85% of the Fund's net assets, none of which is considered restricted. See Note
7 of Notes to Financial Statements.

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

3. Partial or fully-loaned security--See Note 8 of Notes to Financial
Statements.

4. When-issued security or forward commitment to be delivered and settled after
June 30, 2005. See Note 1 of Notes to Financial Statements.

5. 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 $20,753,847 or 2.72% of the Fund's net assets
as of June 30, 2005.

6. 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 $1,398,267 or 0.18% of the Fund's net assets as of
June 30, 2005.

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

8. All or a portion of the security is held in collateralized accounts to cover
initial margin requirements on open futures sales contracts. The aggregate
market value of such securities is $4,593,927. See Note 5 of Notes to Financial
Statements.

9. 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 $16,093,884 or 2.11% of the Fund's net
assets as of June 30, 2005.

10. Issue is in default. See Note 1 of Notes to Financial Statements.

11. Non-income producing security.

12. This bond has no contractual maturity date, is not redeemable and
contractually pays an indefinite stream of interest.

13. Received as the result of issuer reorganization.

14. The security has been segregated to satisfy the forward commitment to return
the cash collateral received in securities lending transactions upon the
borrower's return of the securities loaned. See Note 8 of Notes to Financial
Statements.

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Core Bond Fund (the Fund), formerly Oppenheimer Bond 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. On
January 14, 2005, shareholders of the Fund approved a modification to the Fund's
investment objective. Effective January 21, 2005, the Fund's investment
objective is to seek total return by investing mainly in debt instruments.
Previously, the Fund's investment objective was to seek a high level of current
income 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 listed
or traded on National Stock Exchanges or other domestic or foreign exchanges are
valued based on the last sale price of the security traded on that exchange
prior to the time when the Fund's assets are valued. Securities traded on NASDAQ
are valued based on the closing price provided by NASDAQ prior to the time when
the Fund's assets are valued. In the absence of a sale, the security is valued
at the last sale price on the prior trading day, if it is within the spread of
the closing "bid" and "asked" prices, and if not, at the closing bid price.
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 trading session ending at, or most recently prior to, the time
when the Fund's assets are valued. Securities

1. SIGNIFICANT ACCOUNTING POLICIES Continued

may be valued primarily using dealer-supplied valuations or a portfolio pricing
service authorized by the Board of Trustees. Securities (including restricted
securities) for which market quotations are not readily available are valued at
their fair value. Foreign and domestic securities whose values have been
materially affected by what the Manager identifies as a significant event
occurring before the Fund's assets are valued but after the close of their
respective exchanges will be fair valued. Fair value is determined in good faith
using consistently applied procedures under the supervision of the Board of
Trustees. Short-term "money market type" debt securities with remaining
maturities of sixty days or less are valued at amortized cost (which
approximates market value).

- --------------------------------------------------------------------------------
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 can take place up to 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, 2005, the Fund had purchased $368,496,919
of securities issued on a when-issued basis or forward commitment and sold
$91,006,746 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.


                         40 | OPPENHEIMER CORE BOND FUND


- --------------------------------------------------------------------------------
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, 2005, securities with an aggregate
market value of $259,625, representing 0.03% of the Fund's net assets, were in
default.

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

- --------------------------------------------------------------------------------
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, 2005, the Fund had available for federal income tax
purposes an estimated capital loss carryforward of $26,089. 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,
2005, it is estimated that the Fund will utilize $1,981,270 of capital loss
carryforward to offset realized capital gains. During the year ended December
31, 2004, the Fund utilized $10,865,230 of capital loss carryforward to offset
capital gains realized in that fiscal year.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

As of December 31, 2004, the Fund had available for federal income tax purposes
unused capital loss carryforward as follows:

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Board of Trustees has adopted a deferred
compensation plan for independent trustees that enables trustees to elect to
defer receipt of all or a portion of the annual compensation they are entitled
to receive from the Fund. For purposes of determining the amount owed to the
Trustee under the plan, deferred amounts are treated as though equal dollar
amounts had been invested in shares of the Fund or in other Oppenheimer funds
selected by the Trustee. The Fund purchases shares of the funds selected for
deferral by the Trustee in amounts equal to his or her deemed investment,
resulting in a Fund asset equal to the deferred compensation liability. Such
assets are included as a component of "Other" within the asset section of the
Statement of Assets and Liabilities. Deferral of trustees' fees under the plan
will not affect the net assets of the Fund, and will not materially affect the
Fund's assets, liabilities or net investment income per share. Amounts will be
deferred until distributed in accordance to the Plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date. Income 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 at a rate equal to the Federal
Funds Rate plus 0.50%. The Reduction to Custodian Expenses line item, if
applicable, represents earnings on cash balances maintained by the Fund during
the period. Such interest expense and other custodian fees may be paid with
these earnings.

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


                         42 | OPPENHEIMER CORE BOND FUND


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

pay dealers, brokers, banks and other financial institutions quarterly 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
years. Fees incurred by the Fund under the Plan are detailed in the Statement of

also receives a service fee of up to 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 plan at June 30, 2005
for Class B, Class C and Class N shares were $3,359,784, $1,809,987 and
$512,161, 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 table below for the period indicated.

WAIVERS AND REIMBURSEMENTS OF EXPENSES. Effective March 1, 2004, the Manager has
voluntarily undertaken to limit the "Total Annual Operating Expenses" for all
classes of shares so that "Total Annual Operating 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, 2005, the Manager reimbursed the Fund $305,016, $171,107,
$90,220, $38,717 and $55,625 for Class A, Class B, Class C, Class N and Class Y,
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.
During the six months ended June 30, 2005, OFS waived $7,238 for Class N shares.
This undertaking may be amended or withdrawn at any time.

5. 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.

      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 as 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, 2005, the Fund had outstanding futures contracts as follows:



                                                                                      UNREALIZED

6. TOTAL RETURN SWAP CONTRACTS

The Fund may enter into a total return swap transaction to maintain a total
return on a particular investment, or portion of its portfolio, or for other
non-speculative purposes. Because the principal amount is not exchanged, it
represents neither an asset nor a liability to either counterparty, and is
referred to as notional. The Fund records an increase or decrease to unrealized
gain (loss), in the amount due to or owed by the Fund at termination or
settlement. Total return swaps are subject to risks (if the counterparty fails
to meet its obligations).

As of June 30, 2005, the Fund had entered into the following total return swap
agreements:



                                           PAID BY        RECEIVED BY

7. ILLIQUID OR RESTRICTED SECURITIES

As of June 30, 2005, investments in securities included issues that are illiquid
or restricted. Restricted securities are purchased in private placement
transactions, are not registered under the Securities Act of 1933, may have
contractual restrictions on resale, and are valued under methods approved by the
Board of Trustees as reflecting fair value. A security may also be considered
illiquid if it lacks a readily available market or if its valuation has not
changed for a certain period of time. The Fund will not invest more than 15% of
its net assets (determined at the time of purchase and reviewed periodically) in
illiquid or restricted securities. Certain restricted securities, eligible for
resale to qualified institutional investors, are not subject to that limitation.
Securities that are illiquid or restricted are marked with the applicable
footnote on the Statement of Investments. Information concerning restricted
securities is as follows:

8. 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 US
Treasury obligations 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 of the funds 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.
Cash collateral is invested in cash equivalents. The Fund retains a portion of
the interest earned from the collateral. The Fund also continues to receive
interest or dividends paid on the securities loaned. As of June 30, 2005, the
Fund had on loan securities valued at $68,201,035. Collateral of $69,424,840 was
received for the loans, of which $57,365,537 was received in cash and
subsequently invested in approved instruments.

- --------------------------------------------------------------------------------
9. LITIGATION

A consolidated amended complaint has been filed as putative derivative and class
actions against the Manager, OFS and the Distributor, as well as 51 of the
Oppenheimer funds (as "Nominal Defendants") including the Fund, 30 present and
former Directors or Trustees and 8 present and former officers of the funds.
This complaint, initially filed in the U.S. District Court for the Southern
District of New York on January 10, 2005 and amended on March 4, 2005,
consolidates into a single action and amends six individual previously filed
putative derivative and class action complaints. Like those prior complaints,
the complaint alleges that the Manager charged excessive fees for distribution
and other costs, improperly used assets of the funds in the form of directed
brokerage commissions and 12b-1 fees to pay brokers to promote sales of the
funds, and failed to properly disclose the use of assets of the funds to make
those payments in violation of the Investment Company Act of 1940 and the
Investment Advisers Act of 1940. Also, like those prior complaints, the
complaint further alleges that by permitting and/or participating in those
actions, the Directors/Trustees and the Officers breached their fiduciary duties
to shareholders of the funds under the Investment Company Act of 1940 and at
common law. The complaint seeks unspecified compensatory and punitive damages,
rescission of the funds' investment advisory agreements, an accounting of all
fees paid, and an award of attorneys' fees and litigation expenses.

      The defendants believe that the allegations contained in the Complaints
are without merit and that they have meritorious defenses against the claims
asserted. The defendants intend to defend these lawsuits vigorously and to
contest any claimed liability. The defendants believe that it is premature to
render any opinion as to the likelihood of an outcome unfavorable to them and
that no estimate can yet be made with any degree of certainty as to the amount
or range of any potential loss.

BOARD APPROVAL OF THE FUND'S INVESTMENT ADVISORY AGREEMENT  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Each year, the Board of Trustees (the "Board"), including a majority of the
independent Trustees, is required to determine whether to renew the Fund's
advisory agreement. The Investment Company Act of 1940, as amended, requires
that the Board request and evaluate, and that the Manager provide, such
information as may be reasonably necessary to evaluate the terms of the advisory
agreement. The Board employs an independent consultant to prepare a report that
provides information, including comparative information, that the Board requests
for this purpose. In addition, the Board receives information throughout the
year regarding Fund services, fees, expenses and performance.

      NATURE AND EXTENT OF SERVICES. In considering the renewal of the Fund's
advisory agreement for the current year, the Board evaluated the nature and
extent of the services provided by the Manager and its affiliates. The Manager
provides the Fund with office space, facilities and equipment; administrative,
accounting, clerical, legal and compliance personnel; securities trading
services; oversight of third party service providers and the services of the
portfolio managers and the Manager's investment team, who provide research,
analysis and other advisory services in regard to the Fund's investments.

      QUALITY OF SERVICES. The Board also considered the quality of the services
provided and the quality of the Manager's resources that are available to the
Fund. The Board noted that the Manager has had over forty years of experience as
an investment adviser and that its assets under management rank it among the top
mutual fund managers in the United States. The Board evaluated the Manager's
administrative, accounting, legal and compliance services and information the
Board received regarding the experience and professional qualifications of the
Manager's personnel and the size and functions of its staff. The Board members
also considered their experiences as directors or trustees of the Fund and other
funds advised by the Manager. The Board received and reviewed information
regarding the quality of services provided by affiliates of the Manager, which
it also reviews at other times during the year in connection with the renewal of
the Fund's service agreements. The Board was aware that there are alternatives
to retaining the Manager.

      PORTFOLIO MANAGEMENT SERVICES AND PERFORMANCE. In its evaluation of the
quality of the portfolio management services to be provided, the Board
considered the experience of the Fund's portfolio managers and the Manager's
fixed-income investment team and analysts. The Fund has been managed by a
portfolio management team comprised of Angelo Manioudakis, Benjamin Gord and
Charles Moon since April 2002. Mr. Manioudakis has been a Senior Vice President
of the Manager and of HarbourView Asset Management Corporation since April 2002
and a Senior Vice President of OFI Institutional Asset Management, Inc. since
June 2002. Mr. Gord and Mr. Moon have been Vice Presidents of the

BOARD APPROVAL OF THE FUND'S INVESTMENT ADVISORY AGREEMENT
Unaudited / Continued
- --------------------------------------------------------------------------------

Manager since April 2002. Messrs. Manioudakis, Gord and Moon have each had
between 10 and 15 years of experience managing fixed-income investments.

      The Board also reviewed information, prepared by the Manager and by the
independent consultant, comparing the Fund's historical performance to relevant
market indices and to the performance of other A-rated corporate debt funds
(including both funds advised by the Manager and funds advised by other
investment advisers). The Board also receives and reviews comparative
performance information regarding the Fund and other funds at each Board
meeting. The Board noted that the Fund's five-year and ten-year performance was
below its peer group average. However, the Fund's one-year and three-year
performance was better than its peer group average.

      MANAGEMENT FEES AND EXPENSES. The Board also reviewed information,
including comparative information, regarding the fees paid to the Manager and
its affiliates and the other expenses borne by the Fund. The independent
consultant provided comparative data in regard to the fees and expenses of the
Fund, other A-rated corporate debt funds and other funds with comparable asset
levels and distribution features. The Manager has agreed to voluntarily limit
the "Total Annual Operating Expenses" for all classes of shares so that "Total
Annual Operating Expenses," as percentages of average daily net assets, will not
exceed: 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. The
Board noted that the Fund's contractual and actual management fees and its total
expenses are all lower than its peer group average. In addition, the Board
evaluated the comparability of the fees charged and the services provided to the
Fund to the fees charged and services provided to other types of entities
advised by the Manager.

      PROFITABILITY OF THE MANAGER AND AFFILIATES. The Board also reviewed
information regarding the cost of services provided by the Manager and its
affiliates and the Manager's profitability. The Board considered that the
Manager must be able to pay and retain experienced professional personnel at
competitive rates to provide services to the Fund and that maintaining the
financial viability of the Manager is important in order for the Manager to
continue to provide significant services to the Fund and its shareholders. In
addition the Board considered information that was provided regarding the direct
and indirect benefits the Manager receives as a result of its relationship with
the Fund, including compensation paid to the Manager's affiliates.

      ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may
realize economies of scale in managing and supporting the Fund and the current
level of Fund assets in relation to the Fund's breakpoint schedule for its
management fees. The


                         52 | OPPENHEIMER CORE BOND FUND


Board considered that the Fund has not experienced recent asset growth and that,
based on current asset levels, the Fund is not yet approaching its last
management fee breakpoint.

      CONCLUSIONS. These factors were also considered by the independent
Trustees meeting separately from the full Board, assisted by experienced counsel
to the Fund and to the independent Trustees. Fund counsel and the independent
Trustees' counsel are both independent of the Manager within the meaning and
intent of the Securities and Exchange Commission Rules.

      Based on its review of the information it received and its evaluations
described above, the Board, including a majority of the independent Trustees,
concluded that the nature, extent and quality of the services provided to the
Fund by the Manager are a benefit to the Fund and in the best interest of the
Fund's shareholders and that the amount and structure of the compensation
received by the Manager and its affiliates are reasonable in relation to the
services provided. Accordingly, the Board elected to continue the advisory
agreement for another year. In arriving at this decision, the Board did not
single out any factor or factors as being more important than others, but
considered all of the factors together. The Board judged the terms and
conditions of the advisory agreement, including the management fee, in light of
all of the surrounding circumstances.

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

      1.    The Funds' 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 June 30, 2005 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 has materially affected, or is 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.
