FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE FUND PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF
THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED DECEMBER 31, 2005, FOLLOWED
BY A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE
BROAD-BASED MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. The Oppenheimer Core Bond Fund
delivered a favorable, competitive yield and total return for the 12-month
period ended December 31, 2005, during which the Fund outpaced the median of its
peer group of similarly managed funds while only slightly trailing its primary
benchmark, the Citigroup Broad Investment Grade Bond Index. The Fund's positive
fiscal-year results can be attributed primarily to active management of the
portfolio's exposure to interest-rate risk, and secondarily, to sector decisions
and individual security selection among corporate bonds and agency and
mortgage-related securities.

      Throughout the period, we generally kept the portfolio's duration, or
interest-rate sensitivity, significantly lower than that of our benchmark. Since
the year was underscored by generally rising rates, this decision proved to be
the most prominent contributor to performance for the year. At the same time,
while maintaining our less-than-market exposure to interest-rate risk, we made
slight adjustments to our interest-rate positioning at various points throughout
the year so as to capitalize on interest-rate shifts and movements in the yield
curve as they occurred. As such, our flexible, active management of the
portfolio's duration, while maintaining an overall short duration position, also
substantially benefited returns.

      Although our overall exposure to the mortgage sector did not support
performance as strongly as it did last year, successful security selection
within the mortgage category added to returns this year. For example, our
decision to invest in seasoned, older mortgage securities that were showing
reasonably good levels of prepayment activity helped performance, as these
mortgages managed to fare well amidst a generally struggling mortgage market.

      Within the portfolio's exposure to the credit (corporate bond) sector, our
decision to underweight longer-term, BBB-rated credit securities added to
performance, since this segment of the investment grade corporate bond
market--generally considered to be among the riskiest types of credit securities
in that market--underperformed the corporate sector as a whole. Our
substantially underweighted exposure to these bonds supported the Fund's returns
for the year, as did our decision to underweight industrial bonds, which also
lagged. At the same time, the fact that we chose to overweight our exposure to
the financials sector, particularly to brokerage companies, definitively added
to returns, as this sector of the high-grade corporate market fared well amidst
positive earnings results throughout 2005.

      Finally, our tactical allocation to high-yield bonds in general helped
buoy performance this year. On the negative side, security selection within the
high-yield, or "junk" allocation


                         11 | OPPENHEIMER CORE BOND FUND


FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

of the portfolio detracted from returns. Our decision to own a few, select
high-yield bonds issued by companies in the auto, auto parts and homebuilding
sectors cost us a few basis points of performance, as some of the bonds in these
sectors struggled.

      Similarly, had we maintained the underweighted exposure to longer-maturity
industrial bonds that we established early in the period, we might have
preserved a few basis points of performance. Our decision to move to a neutral
exposure to these bonds later in the year hurt us when these types of corporate
bonds lagged the general market.

COMPARING THE FUND'S PERFORMANCE TO THE MARKET. The graphs that follow show the
performance of a hypothetical $10,000 investment in each class of shares of the
Fund held until December 31, 2005. In the case of Class A, Class B and Class C
shares, performance is measured over a ten-fiscal-year period. In the case of
Class N shares, performance is measured from inception of the Class on March 1,
2001. In the case of Class Y shares, performance is measured from inception of
the Class on April 27, 1998. The Fund's performance reflects the deduction of
the maximum initial sales charge on Class A shares, the applicable contingent
deferred sales charge on Class B, Class C and Class N shares, and reinvestments
of all dividends and capital gains distributions. Past performance cannot
guarantee future results.

      Beginning January 21, 2005, the Fund changed its primary benchmark index
from the Lehman Brothers Credit Index to the Citigroup Broad Investment Grade
Bond Index ("Citigroup Index") because the Fund believes that the Citigroup
Index is a more appropriate benchmark reflecting the types of securities in
which the Fund invests. The Citigroup Index consists of securities having a
higher grade and a lower modified duration than the securities in the Lehman
Brothers Credit Index.

      The Fund's performance is compared to the performance of its former
primary benchmark, the Lehman Brothers Credit Index, a broad-based, unmanaged
index of publicly-issued non-convertible investment grade corporate debt of U.S.
issuers, widely recognized as a measure of the U.S. fixed-rate corporate bond
market. Performance is also compared to its primary benchmark, the Citigroup
Broad Investment Grade Bond Index, a market-capitalization weighted index that
includes fixed-rate Treasury, government-sponsored, corporate and mortgage
securities. The Fund has also added a secondary benchmark, the Lehman Brothers
Aggregate Bond Index, an unmanaged index of U.S. corporate and government bonds,
to which its performance is compared. Index performance reflects the
reinvestment of income but does not consider the effect of transaction costs,
and none of the data in the graphs shows the effect of taxes. The Fund's
performance reflects the effects of the Fund's business and operating expenses.
While index comparisons may be useful to provide a benchmark for the Fund's
performance, it must be noted that the Fund's investments are not limited to the
investments in the index.

THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH DOES NOT
GUARANTEE FUTURE RESULTS. THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN

THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH DOES NOT
GUARANTEE FUTURE RESULTS. THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN
INVESTMENT IN THE FUND WILL FLUCTUATE SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. CURRENT
PERFORMANCE MAY BE LOWER OR HIGHER THAN THE PERFORMANCE QUOTED. FOR PERFORMANCE
DATA CURRENT TO THE MOST RECENT MONTH END, VISIT US AT WWW.OPPENHEIMERFUNDS.COM,
OR CALL US AT 1.800.525.7048. FUND RETURNS INCLUDE CHANGES IN SHARE PRICE,
REINVESTED DISTRIBUTIONS, AND THE APPLICABLE SALES CHARGE: FOR CLASS A SHARES,
THE CURRENT MAXIMUM INITIAL SALES CHARGE OF 4.75%; FOR CLASS B SHARES, THE
CONTINGENT DEFERRED SALES CHARGE OF 5% (1-YEAR) AND 2% (5-YEAR); AND FOR CLASS C
AND N SHARES, THE 1% CONTINGENT DEFERRED SALES CHARGE FOR THE 1-YEAR PERIOD.
THERE IS NO SALES CHARGE FOR CLASS Y SHARES. BECAUSE CLASS B SHARES CONVERT TO
CLASS A SHARES 72 MONTHS AFTER PURCHASE, 10-YEAR RETURNS FOR CLASS B SHARES USES
CLASS A PERFORMANCE FOR THE PERIOD AFTER CONVERSION. SEE PAGE 18 FOR FURTHER
INFORMATION.

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

Total returns and the ending account values in the graphs include changes in
share price and reinvestment of dividends and capital gains distributions in a
hypothetical investment for the periods shown. The Fund's total returns shown do
not reflect the deduction of income taxes on an individual's investment. Taxes
may reduce your actual investment returns on income or gains paid by the Fund or
any gains you may realize if you sell your shares.

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


                         18 | 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
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 December 31, 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


                         20 | OPPENHEIMER CORE BOND FUND


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

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 184/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended December 31, 2005 are as follows:

CLASS            EXPENSE RATIOS
- -------------------------------
Class A               0.89%
- -------------------------------
Class B               1.63
- -------------------------------
Class C               1.64
- -------------------------------
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.

STATEMENT OF INVESTMENTS  Continued
- --------------------------------------------------------------------------------

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 $27,003,045 or 2.90% of the Fund's net
assets as of December 31, 2005.

3. Illiquid or restricted security. The aggregate value of illiquid or
restricted securities as of December 31, 2005 was $2,613,697, which represents
0.28% of the Fund's net assets, none of which is considered restricted. See Note
7 of Notes to Financial Statements.

4. When-issued security or forward commitment to be delivered and settled after
December 31, 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 $32,445,492 or 3.49% of the Fund's net assets
as of December 31, 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 $3,361,486 or 0.36% of the Fund's net assets as of
December 31, 2005.

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

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

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. 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 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 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, in the country that is 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

NOTES TO FINANCIAL STATEMENTS  Continued

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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 (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 December 31, 2005, the Fund had purchased
$277,324,641 of securities issued on a when-issued basis or forward commitment
and sold $66,242,815 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


                         48 | OPPENHEIMER CORE BOND FUND


receive inferior securities at redelivery as compared to the securities sold to
the counter-party; counterparty credit risk; and the potential pay down speed
variance between the mortgage-related pools.

- --------------------------------------------------------------------------------
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 December 31, 2005, securities with an
aggregate market value of $66,695, representing 0.01% 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.

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

1. As of December 31, 2005, the Fund had $7,251,448 of net capital loss
carryforwards available to offset future realized capital gains, if any, and
thereby reduce future taxable gain distributions. As of December 31, 2005,
details of the capital loss carryforwards were as follows:

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

2. During the fiscal year ended December 31, 2005, the Fund did not utilize any
capital loss carryforward.

3. During the fiscal year ended December 31, 2004, the Fund utilized $10,865,230
of capital loss carryforward to offset capital gains realized in that fiscal
year.

Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Fund. Accordingly, the
following amounts have been reclassified for December 31, 2005. Net assets of
the Fund were unaffected by the reclassifications.

difference between book and tax appreciation or depreciation of securities and

- --------------------------------------------------------------------------------
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 to the extent they are not
offset by positive cash balances maintained by the Fund. 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. At December 31, 2005, the
Fund had

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 year ended December 31, 2005, the Manager
reimbursed the Fund $673,792, $353,012, $193,931,


                         54 | OPPENHEIMER CORE BOND FUND


$86,056 and $93,972 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 year ended December 31, 2005, OFS waived $10,938 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.

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 unrealized gain (loss) related to the valuation of
such contracts as well as the amount due to (owed by) the Fund at termination or
settlement is combined and separately disclosed as an asset (liability) on the
Statement of Assets and Liabilities. The Fund also records any periodic payments
received from (paid to) the counterparty under such contracts as realized gain
(loss) on the Statement of Operations. Total return swaps are subject to risks
(if the counterparty fails to meet its obligations).

As of December 31, 2005, the Fund had entered into the following total return
swap agreements:



SWAP                                                                NOTIONAL       TERMINATION         UNREALIZED

                      Floating Rate Payer Payment Amount
                      is positive, the Counterparty will pay
                      such amount to the Fund. If the sums
                      are negative, then the Fund shall pay

7. ILLIQUID OR RESTRICTED SECURITIES

As of December 31, 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 U.S.
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 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 December 31,
2005, the Fund had on loan securities valued at $48,959,258. Collateral of
$49,810,823 was received for the loans, of which $37,556,713 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

9. LITIGATION Continued

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.

10. FUND REORGANIZATION

On September 14, 2005, the Board of Trustees of Oppenheimer Total Return Bond
Fund ("Total Return Bond Fund") approved a proposal to reorganize Total Return
Bond Fund with and into the Fund. A Special Meeting of the Shareholders of Total
Return Bond Fund is scheduled for March 15, 2006 to approve an Agreement and
Plan of Reorganization between Total Return Bond Fund and the Fund, and the
transactions contemplated thereby, including (a) the transfer of substantially
all the assets of Total Return Bond Fund to the Fund in exchange for Class A,
Class B, Class C, and Class N shares of the Fund, (b) the distribution of Class
A, Class B, Class C, and Class N shares of the Fund to the Class A, Class B,
Class C, and Class N shareholders of Total Return Bond Fund in complete
liquidation of Total Return Bond Fund and (c) the cancellation of the
outstanding shares of Total Return Bond Fund.

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

- --------------------------------------------------------------------------------
TO THE BOARD OF TRUSTEE AND SHAREHOLDERS OF OPPENHEIMER CORE BOND FUND:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer Core Bond Fund, a series of Oppenheimer Integrity Funds, including
the statement of investments, as of December 31, 2005, and the related statement
of operations for the year then ended, the statements of changes in net assets
for each of the two years in the period then ended, and the financial highlights
for each of the five years in the periods presented. These financial statements
and financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

      We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
The Fund is not required to have, nor were we engaged to perform, an audit of
its internal control over financial reporting. Our audit includes consideration
of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of December 31, 2005, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Oppenheimer Core Bond Fund as of December 31, 2005, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the five years in the periods presented, in conformity with accounting
principles generally accepted in the United States of America.

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

- --------------------------------------------------------------------------------
In early 2006, if applicable, shareholders of record received information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2005. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

      Recent tax legislation allows a regulated investment company to designate
distributions not designated as capital gain distributions, as either interest
related dividends or short-term capital gain dividends, both of which are exempt
from the U.S. withholding tax applicable to non U.S. taxpayers. For the fiscal
year ended December 31, 2005, $31,371,839 or 98.70% of the ordinary
distributions paid by the Fund qualifies as an interest related dividend. The
Fund did not distribute a short-term capital gain.

      The foregoing information is presented to assist shareholders in reporting
distributions received from the Fund to the Internal Revenue Service. Because of
the complexity of the federal regulations which may affect your individual tax
return and the many variations in state and local tax regulations, we recommend
that you consult your tax advisor for specific guidance.

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
investment advisory agreement (the "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 Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information, that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Fund services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Fund and the Manager,
(iii) the fees and expenses of the Fund, including comparative expense
information, (iv) the profitability of the Manager, including an analysis of the
cost of providing services, (v) whether economies of scale are realized as the
Fund grows and whether fee levels reflect these economies of scale for Fund
investors and (vi) other benefits to the Manager from its relationship with the
Fund. Outlined below is a summary of the principal information considered by the
Board as well as the Board's conclusions.

      NATURE, QUALITY, AND EXTENT OF SERVICES. The Board considered information
on the nature and extent of the services provided to the Fund and information
regarding the Manager's key personnel that provide such services. The Manager's
duties include providing the Fund with the services of the portfolio manager and
the Manager's investment team, who provide research, analysis and other advisory
services in regard to the Fund's investments; securities trading services;
oversight of third party service providers; monitoring compliance with
applicable Fund policies and procedures and adherence to the Fund's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Fund as well. Those services include providing and supervising
all administrative and clerical personnel that are necessary in order to provide
effective corporate administration for the Fund; compiling and maintaining
records with respect to the Fund's operations; preparing and filing reports
required by the Securities and Exchange Commission; preparing periodic reports
regarding the operations of the Fund for its shareholders; preparing proxy
materials for shareholder meetings; and preparing the registration statements
required by Federal and state securities laws for the sale of the Fund's shares.
The Manager also provides the Fund with office space, facilities and equipment.


                         62 | OPPENHEIMER CORE BOND FUND


      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
took account of the fact 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 has received regarding the experience and professional qualifications of
the Manager's key personnel and the size and functions of its staff providing
investment management services to the Fund. The Board also considered compliance
reports from the Fund's Chief Compliance Officer. In its evaluation of the
quality of the portfolio management services 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, Charles Moon,
Geoffrey Caan and Antulio N. Bomfim. Messrs. Manioudakis, Gord, Caan, Moon and
Bomfim have each had between 11 and 15 years of experience managing fixed-income
investments. The Board members also considered the totality of their experiences
with the Manager, as directors or trustees of the Fund and other funds advised
by the Manager. In light of the foregoing, the Board concluded that the Fund
benefits from the services provided under the Agreement as a result of the
Manager's experience, reputation, personnel, operations, and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the
Manager provided information on the performance of the Fund and the Manager at
each Board meeting, including comparative performance information. 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 intermediate investment-grade debt funds
(including both funds advised by the Manager and funds advised by other
investment advisers). The Board noted that the Fund's one-year, three-year,
five-year and ten-year performance were all better than its peer group median.

      COSTS OF SERVICES AND PROFITS REALIZED BY THE MANAGER. The Board
considered in formation regarding the Manager's costs in serving as the Fund's
investment adviser, including the costs associated with the personnel and
systems necessary to manage the Fund, and information regarding the Manager's
profitability from its relationship with the Fund. The Board reviewed the fees
paid to the Manager and the other expenses borne by the Fund. The Board also
evaluated the comparability of the fees charged and the services provided to the
Fund to the fees and services for other clients or accounts advised

BOARD APPROVAL OF THE FUND'S INVESTMENT

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

by the Manager. The independent consultant provided comparative data in regard
to the fees and expenses of the Fund, other intermediate investment-grade debt
funds and other funds with comparable asset levels and distribution features.
The Board noted that the Fund's contractual and actual management fees and total
expenses, which are all lower than its peer group median and average. In light
of this, the Board concluded that the management fee was reasonable.

      ECONOMIES OF SCALE. The Board considered whether the Manager may realize
economies of scale in managing and supporting the Fund, whether those economies
of scale benefit the Fund's shareholders and the current level of Fund assets in
relation to the Fund's management fee breakpoints, which are intended to share
with shareholders economies of scale that may exist as the Fund grows.

      OTHER BENEFITS TO THE MANAGER. In addition to considering the profits
realized by the Manager, 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. The Board also considered the nature and quality of services
provided by affiliates of the Manager, which it reviews at other times during
the year in connection with the renewal of the Fund's service agreements. 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.

      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,
decided 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 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 December 31, 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



have materially affected, or are reasonably likely to materially affect, the
registrant's internal control over financial reporting.
