These securities have been determined to be liquid under guidelines established by the Board of Trustees. These securities amount to $572,362,829 or 27.30% of the Fund’s net assets at period end.

2. Represents the current interest rate for a variable or increasing rate security, determined as [Referenced Rate + Basis-point spread].

3. Interest-Only Strips represent the right to receive the monthly interest payments on an underlying pool of mortgage loans. These securities typically decline in price as interest rates decline. Most other fixed income securities increase in price when interest rates decline. The principal amount of the underlying pool represents the notional amount on which current interest is calculated. The price of these securities is typically more sensitive to changes in prepayment rates than traditional mortgage-backed securities (for example, GNMA pass-throughs). Interest rates disclosed represent current yields based upon the current cost basis and estimated timing and amount of future cash flows. These securities amount to $16,720,692 or 0.80% of the Fund’s net assets at period end.

4. Interest rate is less than 0.0005%.

5. Principal-Only Strips represent the right to receive the monthly principal payments on an underlying pool of mortgage loans. The value of these securities generally increases as interest rates decline and prepayment rates rise. The price of these securities is typically more volatile than that of coupon-bearing bonds of the same maturity. Interest rates disclosed represent current yields based upon the current cost basis and estimated timing of future cash flows. These securities amount to $88,895 or less than 0.005% of the Fund’s net assets at period end.

6. All or a portion of the security position is when-issued or delayed delivery to be delivered and settled after period end. See Note 3 of the accompanying Notes.

7. Restricted security. The aggregate value of restricted securities at period end was $3,041,263, which represents 0.15% of the Fund’s net assets. See Note 3 of the accompanying Notes. Information concerning restricted securities is as follows:

NOTES TO STATEMENT OF INVESTMENTS March 31, 2018 Unaudited

1. Organization

Oppenheimer Total Return Bond Fund (the “Fund”), is a separate fund of Oppenheimer Integrity Funds, a diversified open-end management investment company registered under the Investment Company Act of 1940 (“1940 Act”), as amended. The Fund’s investment objective is to seek total return. The Fund’s investment adviser is OFI Global Asset Management, Inc. (“OFI Global” or the “Manager”), a wholly-owned subsidiary of OppenheimerFunds, Inc. (“OFI” or the “Sub-Adviser”). The Manager has entered into a sub-advisory agreement with OFI.

2. Securities Valuation

The Fund calculates the net asset value of its shares as of 4:00 P.M. Eastern Time, on each day the New York Stock Exchange (the “Exchange”) is open for trading, except in the case of a scheduled early closing of the Exchange, in which case the Fund will calculate net asset value of the shares as of the scheduled early closing time of the Exchange.

The Fund’s Board has adopted procedures for the valuation of the Fund’s securities and has delegated the day-to-day responsibility for valuation determinations under those procedures to the Manager. The Manager has established a Valuation Committee which is responsible for determining a fair valuation for any security for which market quotations are not readily available. The Valuation Committee’s fair valuation determinations are subject to review, approval and ratification by the Fund’s Board at least quarterly or more frequently, if necessary.

Valuation Methods and Inputs

Securities are valued primarily using unadjusted quoted market prices, when available, as supplied by third party pricing services or broker-dealers.

The following methodologies are used to determine the market value or the fair value of the types of securities described below:

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

Corporate and government debt securities (of U.S. or foreign issuers) and municipal debt securities, short-term notes, mortgage-backed securities, collateralized mortgage obligations, and asset-backed securities are valued at the mean between the bid and asked prices utilizing evaluated prices obtained from third party pricing services or broker-dealers who may use matrix pricing methods to determine the evaluated prices. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, sometimes at lower prices than institutional round lot trades. Standard inputs generally considered by third-party pricing vendors include reported trade data, broker-dealer price quotations, benchmark yields, issuer spreads on comparable securities, the credit quality, yield, maturity, as well as other appropriate factors.

Futures contracts and futures options 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,

32        OPPENHEIMER TOTAL RETURN BOND FUND

2. Securities Valuation (Continued)

the time when the Fund’s assets are valued.

Securities for which market quotations are not readily available, or when a significant event has occurred that would materially affect the value of the security, are fair valued either (i) by a standardized fair valuation methodology applicable to the security type or the significant event as previously approved by the Valuation Committee and the Fund’s Board or (ii) as determined in good faith by the Manager’s Valuation Committee. The Valuation Committee considers all relevant facts that are reasonably available, through either public information or information available to the Manager, when determining the fair value of a security. Those standardized fair valuation methodologies include, but are not limited to, valuing securities at the last sale price or initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be further adjusted for any discounts related to security-specific resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted quoted prices of similar securities, observable interest rates, currency rates and yield curves. The methodologies used for valuing securities are not necessarily an indication of the risks associated with investing in those securities nor can it be assured that the Fund can obtain the fair value assigned to a security if it were to sell the security.

To assess the continuing appropriateness of security valuations, the Manager regularly compares prior day prices and sale prices to the current day prices and challenges those prices exceeding certain tolerance levels with the third party pricing service or broker source. For those securities valued by fair valuations, whether through a standardized fair valuation methodology or a fair valuation determination, the Valuation Committee reviews and affirms the reasonableness of the valuations based on such methodologies and fair valuation determinations on a regular basis after considering all relevant information that is reasonably available.

Classifications

Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Various data inputs may be used in determining the value of each of the Fund’s investments as of the reporting period end.

These data inputs are categorized in the following hierarchy under applicable financial accounting standards:

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

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

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

The inputs used for valuing securities are not necessarily an indication of the risks associated

33        OPPENHEIMER TOTAL RETURN BOND FUND

NOTES TO STATEMENT OF INVESTMENTS Unaudited / Continued

2. Securities Valuation (Continued)

with investing in those securities.

The Fund classifies each of its investments in investment companies which are publicly offered as Level 1. Investment companies that are not publicly offered, if any, are classified as Level 2 in the fair value hierarchy.

3. Investments and Risks

Investments in Affiliated Funds. The Fund is permitted to invest in other mutual funds advised by the Manager (“Affiliated Funds”). Affiliated Funds are open-end management investment companies registered under the 1940 Act, as amended. The Manager is the investment adviser of, and the Sub-Adviser provides investment and related advisory services to, the Affiliated Funds. When applicable, the Fund’s investments in Affiliated Funds are included in the Statement of Investments. Shares of Affiliated Funds are valued at their net asset value per share. As a shareholder, the Fund is subject to its proportional share of the Affiliated Funds’ expenses, including their management fee. The Manager will waive fees and/ or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund’s investment in the Affiliated Funds.

Each of the Affiliated Funds in which the Fund invests has its own investment risks, and those risks can affect the value of the Fund’s investments and therefore the value of the Fund’s shares. To the extent that the Fund invests more of its assets in one Affiliated Fund than in another, the Fund will have greater exposure to the risks of that Affiliated Fund.

Investments in Money Market Instruments. The Fund is permitted to invest its free cash balances in money market instruments to provide liquidity or for defensive purposes. The Fund may invest in money market instruments by investing in Class E shares of Oppenheimer Institutional Government Money Market Fund (“IGMMF”), which is an Affiliated Fund. IGMMF is regulated as a money market fund under the 1940 Act, as amended. The Fund may also invest in money market instruments directly or in other affiliated or unaffiliated money market funds.

Securities on a When-Issued or Delayed Delivery Basis. The Fund may purchase securities on a “when-issued” basis, and may purchase or sell securities on a “delayed delivery” basis. “When-issued” or “delayed delivery” refers to securities whose terms and indenture are available and for which a market exists, but which are not available for immediate delivery. Delivery and payment for securities that have been purchased by the Fund on a when-issued basis normally takes place within six months and possibly as long as two years or more after the trade date. During this period, such securities do not earn interest, are subject to market fluctuation and may increase or decrease in value prior to their delivery. The purchase of securities on a when-issued basis may increase the volatility of the Fund’s net asset value to the extent the Fund executes such transactions while remaining substantially fully invested. When the Fund engages in when-issued or delayed delivery transactions, it relies on the buyer or seller, as the case may be, to complete the transaction. Their failure to do so may cause the Fund to lose the opportunity to obtain or dispose of the security at a price and yield it considers advantageous. The Fund may also sell securities that it purchased on a when-issued basis or forward commitment prior to settlement of the original purchase.

At period end, the Fund had purchased securities issued on a when-issued or delayed delivery basis and sold securities issued on a delayed delivery basis as follows:

NOTES TO STATEMENT OF INVESTMENTS Unaudited / Continued

3. Investments and Risks (Continued)

	When-Issued or
	Delayed Delivery
	Basis Transactions
Purchased securities		$842,861,985
Sold securities		183,850,994

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

Forward roll transactions may be deemed to entail embedded leverage since the Fund purchases mortgage-related securities with extended settlement dates rather than paying for the securities under a normal settlement cycle. This embedded leverage increases the Fund’s market value of investments relative to its net assets which can incrementally increase the volatility of the Fund’s performance. Forward roll transactions can be replicated over multiple settlement periods.

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; and counterparty credit risk.

At period end, the counterparty pledged $1,382,109 of collateral to the Fund for forward roll transactions.

At period end, the Fund pledged $1,435,543 of collateral to the counterparty for forward roll transactions.

Restricted Securities. At period end, investments in securities included issues that are restricted. A restricted security may have a contractual restriction on its resale and is valued under methods approved by the Board of Trustees as reflecting fair value. Securities that are restricted are marked with an applicable footnote on the Statement of Investments. Restricted securities are reported on a schedule following the Statement of Investments.

4. Market Risk Factors

The Fund’s investments in securities and/or financial derivatives may expose the Fund to various market risk factors:

Commodity Risk. Commodity risk relates to the change in value of commodities or commodity indexes as they relate to increases or decreases in the commodities market.

36        OPPENHEIMER TOTAL RETURN BOND FUND

4. Market Risk Factors (Continued)

Commodities are physical assets that have tangible properties. Examples of these types of assets are crude oil, heating oil, metals, livestock, and agricultural products.

Credit Risk. Credit risk relates to the ability of the issuer of debt to meet interest and principal payments, or both, as they come due. In general, lower-grade, higher-yield debt securities are subject to credit risk to a greater extent than lower-yield, higher-quality securities.

Equity Risk. Equity risk relates to the change in value of equity securities as they relate to increases or decreases in the general market.

Foreign Exchange Rate Risk. Foreign exchange rate risk relates to the change in the U.S. dollar value of a security held that is denominated in a foreign currency. The U.S. dollar value of a foreign currency denominated security will decrease as the dollar appreciates against the currency, while the U.S. dollar value will increase as the dollar depreciates against the currency.

Interest Rate Risk. Interest rate risk refers to the fluctuations in value of fixed-income securities resulting from the inverse relationship between price and yield. For example, an increase in general interest rates will tend to reduce the market value of already issued fixed-income investments, and a decline in general interest rates will tend to increase their value. In addition, debt securities with longer maturities, which tend to have higher yields, are subject to potentially greater fluctuations in value from changes in interest rates than obligations with shorter maturities.

Volatility Risk. Volatility risk refers to the magnitude of the movement, but not the direction of the movement, in a financial instrument’s price over a defined time period. Large increases or decreases in a financial instrument’s price over a relative time period typically indicate greater volatility risk, while small increases or decreases in its price typically indicate lower volatility risk.

5. Use of Derivatives

The Fund’s investment objective not only permits the Fund to purchase investment securities, it also allows the Fund to enter into various types of derivatives contracts, including, but not limited to, futures contracts, forward currency exchange contracts, credit default swaps, interest rate swaps, total return swaps, variance swaps and purchased and written options. In doing so, the Fund will employ strategies in differing combinations to permit it to increase, decrease, or change the level or types of exposure to market risk factors. These instruments may allow the Fund to pursue its objectives more quickly and efficiently than if it were to make direct purchases or sales of securities capable of effecting a similar response to market factors. Such contracts may be entered into through a bilateral over-the-counter (“OTC”) transaction, or through a securities or futures exchange and cleared through a clearinghouse.

Derivatives may have little or no initial cash investment relative to their market value exposure and therefore can produce significant gains or losses in excess of their cost due to changes in the market risk factors and the overall market. This use of embedded leverage allows the Fund to increase its market value exposure relative to its net assets and can

37        OPPENHEIMER TOTAL RETURN BOND FUND

NOTES TO STATEMENT OF INVESTMENTS Unaudited / Continued

5. Use of Derivatives (Continued)

substantially increase the volatility of the Fund’s performance. In instances where the Fund is using derivatives to decrease, or hedge, exposures to market risk factors for securities held by the Fund, there are also risks that those derivatives may not perform as expected resulting in losses for the combined or hedged positions. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment.

Additional associated risks from investing in derivatives also exist and potentially could have significant effects on the valuation of the derivative and the Fund. Typically, the associated risks are not the risks that the Fund is attempting to increase or decrease exposure to, per its investment objectives, but are the additional risks from investing in derivatives. Examples of these associated risks are liquidity risk, which is the risk that the Fund will not be able to sell the derivative in the open market in a timely manner, and counterparty credit risk, which is the risk that the counterparty will not fulfill its obligation to the Fund.

The Fund’s actual exposures to these market risk factors and associated risks during the period are discussed in further detail, by derivative type, below.

Futures Contracts

A futures contract is a commitment to buy or sell a specific amount of a commodity, financial instrument or currency at a negotiated price on a stipulated future date. The Fund may buy and sell futures contracts and may also buy or write put or call options on these futures contracts. Futures contracts and options thereon are generally entered into on a regulated futures exchange and cleared through a clearinghouse associated with the exchange.

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 in an account registered in the futures commission merchant’s name. Subsequent payments (variation margin) are paid to or from the futures commission merchant each day equal to the daily changes in the contract value. Such payments are recorded as unrealized gains and losses. Should the Fund fail to make requested variation margin payments, the futures commission merchant can gain access to the initial margin to satisfy the Fund’s payment obligations.

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

The Fund may purchase and/or sell financial futures contracts and options on futures contracts to gain exposure to, or decrease exposure to interest rate risk, equity risk, foreign exchange rate risk, volatility risk, or commodity risk.

During the reporting period, the Fund had an ending monthly average market value of $191,371,676 and $552,578,755 on futures contracts purchased and sold, respectively.

38        OPPENHEIMER TOTAL RETURN BOND FUND

5. Use of Derivatives (Continued)

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

Counterparty Credit Risk. Derivative positions are subject to the risk that the counterparty will not fulfill its obligation to the Fund. The Fund intends to enter into derivative transactions with counterparties that the Manager believes to be creditworthy at the time of the transaction.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities in the annual and semiannual reports. Bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events.

The Fund’s risk of loss from counterparty credit risk on exchange-traded derivatives cleared through a clearinghouse and for centrally cleared swaps is generally considered lower than as compared to OTC derivatives. However, counterparty credit risk exists with respect to initial and variation margin deposited/paid by the Fund that is held in futures commission merchant, broker and/or clearinghouse accounts for such exchange-traded derivatives and for centrally cleared swaps.

With respect to centrally cleared swaps, such transactions will be submitted for clearing, and if cleared, will be held in accounts at futures commission merchants or brokers that are members of clearinghouses. While brokers, futures commission merchants and clearinghouses are required to segregate customer margin from their own assets, in the event that a broker, futures commission merchant or clearinghouse becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker, futures commission merchant or clearinghouse for all its customers, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s, futures commission merchant’s or clearinghouse’s customers, potentially resulting in losses to the Fund.

There is the risk that a broker, futures commission merchant or clearinghouse will decline to clear a transaction on the Fund’s behalf, and the Fund may be required to pay a termination fee to the executing broker with whom the Fund initially enters into the transaction. Clearinghouses may also be permitted to terminate centrally cleared swaps at any time. The Fund is also subject to the risk that the broker or futures commission merchant will improperly use the Fund’s assets deposited/paid as initial or variation margin to satisfy payment obligations of another customer. In the event of a default by another customer of the broker or futures commission merchant, the Fund might not receive its variation margin payments from the clearinghouse, due to the manner in which variation margin payments are aggregated for all customers of the broker/futures commission merchant.

Collateral and margin requirements differ by type of derivative. Margin requirements are established by the broker, futures commission merchant or clearinghouse for exchange-traded and cleared derivatives, including centrally cleared swaps. Brokers, futures commission

NOTES TO STATEMENT OF INVESTMENTS Unaudited / Continued

5. Use of Derivatives (Continued)

merchants and clearinghouses can ask for margin in excess of the regulatory minimum, or increase the margin amount, in certain circumstances.

For financial reporting purposes, cash collateral that has been pledged to cover obligations of the Fund, if any, is reported separately on the Statement of Assets and Liabilities in the annual and semiannual reports as cash pledged as collateral. Non-cash collateral pledged by the Fund, if any, is noted in the Statement of Investments. Generally, the amount of collateral due from or to a party must exceed a minimum transfer amount threshold (e.g. $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance.

NOTES TO STATEMENT OF INVESTMENTS March 31, 2018 Unaudited

1. Organization

Oppenheimer Global Unconstrained Bond Fund (the “Fund”), is a series of Oppenheimer Integrity Funds, a diversified open-end management investment company registered under the Investment Company Act of 1940 (“1940 Act”), as amended. The Fund’s investment objective is to seek total return. The Fund’s investment adviser is OFI Global Asset Management, Inc. (“OFI Global” or the “Manager”), a wholly-owned subsidiary of OppenheimerFunds, Inc. (“OFI” or the “Sub-Adviser”). The Manager has entered into a sub-advisory agreement with OFI. The Fund commenced operations on January 26, 2018.

2. Significant Accounting Policies

Security Valuation. All investments in securities are recorded at their estimated fair value, as described in Note 3.

Foreign Currency Translation. The books and records of the Fund are maintained in U.S. dollars. Any foreign currency amounts are translated into U.S. dollars on the following basis: (1) Value of investment securities, other assets and liabilities — at the exchange rates prevailing at market close as described in Note 3.

(2) Purchases and sales of investment securities, income and expenses — at the rates of exchange prevailing on the respective dates of such transactions.

3. Securities Valuation

The Fund calculates the net asset value of its shares as of 4:00 P.M. Eastern Time, on each day the New York Stock Exchange (the “Exchange”) is open for trading, except in the case of a scheduled early closing of the Exchange, in which case the Fund will calculate net asset value of the shares as of the scheduled early closing time of the Exchange.

The Fund’s Board has adopted procedures for the valuation of the Fund’s securities and has delegated the day-to-day responsibility for valuation determinations under those procedures to the Manager. The Manager has established a Valuation Committee which is responsible for determining a fair valuation for any security for which market quotations are not readily available. The Valuation Committee’s fair valuation determinations are subject to review, approval and ratification by the Fund’s Board at least quarterly or more frequently, if necessary.

Valuation Methods and Inputs

Securities are valued primarily using unadjusted quoted market prices, when available, as supplied by third party pricing services or broker-dealers.

The following methodologies are used to determine the market value or the fair value of the types of securities described below:

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

Corporate and government debt securities (of U.S. or foreign issuers) and municipal debt securities, short-term notes, mortgage-backed securities, collateralized mortgage obligations,

NOTES TO STATEMENT OF INVESTMENTS Unaudited / Continued

3. Securities Valuation (Continued)

and asset-backed securities are valued at the mean between the bid and asked prices utilizing evaluated prices obtained from third party pricing services or broker-dealers who may use matrix pricing methods to determine the evaluated prices. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, sometimes at lower prices than institutional round lot trades. Standard inputs generally considered by third-party pricing vendors include reported trade data, broker-dealer price quotations, benchmark yields, issuer spreads on comparable securities, the credit quality, yield, maturity, as well as other appropriate factors.

Structured securities, swaps, swaptions, and other over-the-counter derivatives are valued utilizing evaluated prices obtained from third party pricing services or broker-dealers. Standard inputs generally considered by third-party pricing vendors include market information relevant to the underlying reference asset such as the price of financial instruments, stock market indices, foreign currencies, interest rate spreads, commodities, credit spreads, credit event probabilities, index values, individual security values, forward interest rates, variable interest rates, volatility measures, and forward currency rates, or the occurrence of other specific events.

Forward foreign currency exchange contracts are valued utilizing current and forward currency rates obtained from third party pricing services. When the settlement date of a contract is an interim date for which a quotation is not available, interpolated values are derived using the nearest dated forward currency rate.

Securities for which market quotations are not readily available, or when a significant event has occurred that would materially affect the value of the security, are fair valued either (i) by a standardized fair valuation methodology applicable to the security type or the significant event as previously approved by the Valuation Committee and the Fund’s Board or (ii) as determined in good faith by the Manager’s Valuation Committee. The Valuation Committee considers all relevant facts that are reasonably available, through either public information or information available to the Manager, when determining the fair value of a security. Those standardized fair valuation methodologies include, but are not limited to, valuing securities at the last sale price or initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be further adjusted for any discounts related to security-specific resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted quoted prices of similar securities, observable interest rates, currency rates and yield curves. The methodologies used for valuing securities are not necessarily an indication of the risks associated with investing in those securities nor can it be assured that the Fund can obtain the fair value assigned to a security if it were to sell the security.

Classifications

Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Various data inputs may be used in determining the value of each of the Fund’s investments as of the reporting period end.

10        OPPENHEIMER GLOBAL UNCONSTRAINED BOND FUND

3. Securities Valuation (Continued)

These data inputs are categorized in the following hierarchy under applicable financial accounting standards:

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

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

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

The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

The Fund classifies each of its investments in investment companies which are publicly offered as Level 1. Investment companies that are not publicly offered, if any, are classified as Level 2 in the fair value hierarchy.

the contract’s value from trade date. All additional assets and liabilities included in the above table are reported at their market value at measurement date.

4. Investments and Risks

Risks of Foreign Investing. The Fund may invest in foreign securities which are subject to special risks. Securities traded in foreign markets may be less liquid and more volatile than those traded in U.S. markets. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company’s operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of investments denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those investments. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company’s assets, or other political and economic factors. In addition, due to the inter-relationship of global economies and financial markets, changes in political and economic factors in one country or region could adversely affect conditions in another country or region. Investments in foreign securities may also expose the Fund to time-zone arbitrage risk. Foreign securities may trade on weekends or other days when the Fund does not price its shares. At times, the Fund may emphasize investments in a particular country or region and may be subject to greater risks from adverse events that occur in that country or region. Foreign securities and foreign currencies held in foreign banks and securities depositories may be subject to limited or no regulatory oversight.

Investments in Affiliated Funds. The Fund is permitted to invest in other mutual funds advised by the Manager (“Affiliated Funds”). Affiliated Funds are open-end management investment companies registered under the 1940 Act, as amended. The Manager is the investment adviser of, and the Sub-Adviser provides investment and related advisory services to, the Affiliated Funds. When applicable, the Fund’s investments in Affiliated Funds are included in the Statement of Investments. Shares of Affiliated Funds are valued at their net asset value per share. As a shareholder, the Fund is subject to its proportional share of the Affiliated Funds’ expenses, including their management fee. The Manager will waive fees and/ or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund’s investment in the Affiliated Funds.

Each of the Affiliated Funds in which the Fund invests has its own investment risks, and those risks can affect the value of the Fund’s investments and therefore the value of the Fund’s shares. To the extent that the Fund invests more of its assets in one Affiliated Fund than in another, the Fund will have greater exposure to the risks of that Affiliated Fund.

Investments in Money Market Instruments. The Fund is permitted to invest its free cash balances in money market instruments to provide liquidity or for defensive purposes. The

12        OPPENHEIMER GLOBAL UNCONSTRAINED BOND FUND

4. Investments and Risks (Continued)

Fund may invest in money market instruments by investing in Class E shares of Oppenheimer Institutional Government Money Market Fund (“IGMMF”), which is an Affiliated Fund. IGMMF is regulated as a money market fund under the 1940 Act, as amended. The Fund may also invest in money market instruments directly or in other affiliated or unaffiliated money market funds.

Sovereign Debt Risk. The Fund invests in sovereign debt securities, which are subject to certain special risks. These risks include, but are not limited to, the risk that a governmental entity may delay or refuse, or otherwise be unable, to pay interest or repay the principal on its sovereign debt. There may also be no legal process for collecting sovereign debt that a government does not pay or bankruptcy proceedings through which all or part of such sovereign debt may be collected. In addition, a restructuring or default of sovereign debt may also cause additional impacts to the financial markets, such as downgrades to credit ratings, reduced liquidity and increased volatility, among others.

5. Market Risk Factors

The Fund’s investments in securities and/or financial derivatives may expose the Fund to various market risk factors:

Commodity Risk. Commodity risk relates to the change in value of commodities or commodity indexes as they relate to increases or decreases in the commodities market. Commodities are physical assets that have tangible properties. Examples of these types of assets are crude oil, heating oil, metals, livestock, and agricultural products.

Credit Risk. Credit risk relates to the ability of the issuer of debt to meet interest and principal payments, or both, as they come due. In general, lower-grade, higher-yield debt securities are subject to credit risk to a greater extent than lower-yield, higher-quality securities.

Equity Risk. Equity risk relates to the change in value of equity securities as they relate to increases or decreases in the general market.

Foreign Exchange Rate Risk. Foreign exchange rate risk relates to the change in the U.S. dollar value of a security held that is denominated in a foreign currency. The U.S. dollar value of a foreign currency denominated security will decrease as the dollar appreciates against the currency, while the U.S. dollar value will increase as the dollar depreciates against the currency.

Interest Rate Risk. Interest rate risk refers to the fluctuations in value of fixed-income securities resulting from the inverse relationship between price and yield. For example, an increase in general interest rates will tend to reduce the market value of already issued fixed-income investments, and a decline in general interest rates will tend to increase their value. In addition, debt securities with longer maturities, which tend to have higher yields, are subject to potentially greater fluctuations in value from changes in interest rates than obligations with shorter maturities.

Volatility Risk. Volatility risk refers to the magnitude of the movement, but not the

13        OPPENHEIMER GLOBAL UNCONSTRAINED BOND FUND

NOTES TO STATEMENT OF INVESTMENTS Unaudited / Continued

5. Market Risk Factors (Continued)

direction of the movement, in a financial instrument’s price over a defined time period. Large increases or decreases in a financial instrument’s price over a relative time period typically indicate greater volatility risk, while small increases or decreases in its price typically indicate lower volatility risk.

6. Use of Derivatives

The Fund’s investment objective not only permits the Fund to purchase investment securities, it also allows the Fund to enter into various types of derivatives contracts, including, but not limited to, futures contracts, forward currency exchange contracts, credit default swaps, interest rate swaps, total return swaps, variance swaps and purchased and written options. In doing so, the Fund will employ strategies in differing combinations to permit it to increase, decrease, or change the level or types of exposure to market risk factors. These instruments may allow the Fund to pursue its objectives more quickly and efficiently than if it were to make direct purchases or sales of securities capable of effecting a similar response to market factors. Such contracts may be entered into through a bilateral over-the-counter (“OTC”) transaction, or through a securities or futures exchange and cleared through a clearinghouse.

Derivatives may have little or no initial cash investment relative to their market value exposure and therefore can produce significant gains or losses in excess of their cost due to changes in the market risk factors and the overall market. This use of embedded leverage allows the Fund to increase its market value exposure relative to its net assets and can substantially increase the volatility of the Fund’s performance. In instances where the Fund is using derivatives to decrease, or hedge, exposures to market risk factors for securities held by the Fund, there are also risks that those derivatives may not perform as expected resulting in losses for the combined or hedged positions. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment.

Additional associated risks from investing in derivatives also exist and potentially could have significant effects on the valuation of the derivative and the Fund. Typically, the associated risks are not the risks that the Fund is attempting to increase or decrease exposure to, per its investment objectives, but are the additional risks from investing in derivatives. Examples of these associated risks are liquidity risk, which is the risk that the Fund will not be able to sell the derivative in the open market in a timely manner, and counterparty credit risk, which is the risk that the counterparty will not fulfill its obligation to the Fund.

The Fund’s actual exposures to these market risk factors and associated risks during the period are discussed in further detail, by derivative type, below.

Forward Currency Exchange Contracts

The Fund may enter into forward currency exchange contracts (“forward contracts”) for the purchase or sale of a foreign currency at a negotiated rate at a future date. Such contracts are traded in the OTC inter-bank currency dealer market.

Forward contracts are reported on a schedule following the Statement of Investments. The unrealized appreciation (depreciation) is reported in the Statement of Assets and Liabilities

14        OPPENHEIMER GLOBAL UNCONSTRAINED BOND FUND

6. Use of Derivatives (Continued)

in the annual and semiannual reports as a receivable (or payable) and in the Statement of Operations in the annual and semiannual reports within the change in unrealized appreciation (depreciation). At contract close, the difference between the original cost of the contract and the value at the close date is recorded as a realized gain (loss) in the Statement of Operations in the annual and semiannual reports.

The Fund may enter into forward foreign currency exchange contracts in order to decrease exposure to foreign exchange rate risk associated with either specific transactions or portfolio instruments or to increase exposure to foreign exchange rate risk.

During the reporting period, the Fund had daily average contract amounts on forward contracts to buy and sell of $551,793 and $1,113,583, respectively.

Additional associated risk to the Fund includes counterparty credit risk. Counterparty credit risk arises from the possibility that the counterparty to a forward contract will default and fail to perform its obligations to the Fund.

Futures Contracts

A futures contract is a commitment to buy or sell a specific amount of a commodity, financial instrument or currency at a negotiated price on a stipulated future date. The Fund may buy and sell futures contracts and may also buy or write put or call options on these futures contracts. Futures contracts and options thereon are generally entered into on a regulated futures exchange and cleared through a clearinghouse associated with the exchange.

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 in an account registered in the futures commission merchant’s name. Subsequent payments (variation margin) are paid to or from the futures commission merchant each day equal to the daily changes in the contract value. Such payments are recorded as unrealized gains and losses. Should the Fund fail to make requested variation margin payments, the futures commission merchant can gain access to the initial margin to satisfy the Fund’s payment obligations.

Futures contracts are reported on a schedule following the Statement of Investments. Securities held by a futures commission merchant to cover initial margin requirements on open futures contracts are noted in the Statement of Investments. Cash held by a futures commission merchant to cover initial margin requirements on open futures contracts and the receivable and/or payable for the daily mark to market for the variation margin are noted in the Statement of Assets and Liabilities in the annual and semiannual reports. The net change in unrealized appreciation and depreciation is reported in the Statement of Operations in the annual and semiannual reports. Realized gains (losses) are reported in the Statement of Operations in the annual and semiannual reports at the closing or expiration of futures contracts.

The Fund may purchase and/or sell financial futures contracts and options on futures contracts to gain exposure to, or decrease exposure to interest rate risk, equity risk, foreign exchange rate risk, volatility risk, or commodity risk.

Additional associated risks of entering into futures contracts (and related options) include

15        OPPENHEIMER GLOBAL UNCONSTRAINED BOND FUND

NOTES TO STATEMENT OF INVESTMENTS Unaudited / Continued

6. Use of Derivatives (Continued)

the possibility that there may be an illiquid market where the Fund is unable to liquidate the contract or enter into an offsetting position and, if used for hedging purposes, the risk that the price of the contract will correlate imperfectly with the prices of the Fund’s securities.

At period end, the Fund had no futures contracts outstanding.

Option Activity

The Fund may buy and sell put and call options, or write put and call options. When an option is written, the Fund receives a premium and becomes obligated to sell or purchase the underlying security, currency or other underlying financial instrument at a fixed price, upon exercise of the option.

Options can be traded through an exchange or through a privately negotiated arrangement with a dealer in an OTC transaction. Options traded through an exchange are generally cleared through a clearinghouse (such as The Options Clearing Corporation). The difference between the premium received or paid, and market value of the option, is recorded as unrealized appreciation or depreciation. The net change in unrealized appreciation or depreciation is reported in the Statement of Operations in the annual and semiannual reports. When an option is exercised, the cost of the security purchased or the proceeds of the security sale are adjusted by the amount of premium received or paid. Upon the expiration or closing of the option transaction, a gain or loss is reported in the Statement of Operations in the annual and semiannual reports.

Foreign Currency Options. The Fund may purchase or write call and put options on currencies to increase or decrease exposure to foreign exchange rate risk. A purchased call, or written put option becomes more valuable as the price of the underlying financial instrument appreciates relative to the strike price. A purchased put, or written call option becomes more valuable as the price of the underlying financial instrument depreciates relative to the strike price.

During the reporting period, the Fund had an ending monthly average market value of $9,902 and $688 on purchased call options and purchased put options, respectively.

Options written, if any, are reported in a schedule following the Statement of Investments and as a liability in the Statement of Assets and Liabilities in the annual and semiannual reports. Securities held in collateral accounts to cover potential obligations with respect to outstanding written options are noted in the Statement of Investments.

The risk in writing a call option is the market price of the underlying security increasing above the strike price and the option being exercised. The Fund must then purchase the underlying security at the higher market price and deliver it for the strike price or, if it owns the underlying security, deliver it at the strike price and forego any benefit from the increase in the price of the underlying security above the strike price. The risk in writing a put option is the market price of the underlying security decreasing below the strike price and the option being exercised. The Fund must then purchase the underlying security at the strike price when the market price of the underlying security is below the strike price. Alternatively, the Fund could also close out a written option position, in which case the risk is that the closing transaction will require a premium to be paid by the Fund that is greater than the premium the Fund

16        OPPENHEIMER GLOBAL UNCONSTRAINED BOND FUND

6. Use of Derivatives (Continued)

received. When writing options, the Fund has the additional risk that there may be an illiquid market where the Fund is unable to close the contact. The risk in buying an option is that the Fund pays a premium for the option, and the option may be worth less than the premium paid or expire worthless.

During the reporting period, the Fund had an ending monthly average market value of $13,003 and $55,229 on written call options and written put options, respectively.

Additional associated risks to the Fund include counterparty credit risk and liquidity risk.

Swap Contracts

The Fund may enter into swap contract agreements with a counterparty to exchange a series of cash flows based on either specified reference rates, the price or volatility of asset or non-asset references, or the occurrence of a credit event, over a specified period. Swaps can be executed in a bi-lateral privately negotiated arrangement with a dealer in an OTC transaction (“OTC swaps”) or executed on a regulated market. Certain swaps, regardless of the venue of their execution, are required to be cleared through a clearinghouse (“centrally cleared swaps”). Swap contracts may include interest rate, equity, debt, index, total return, credit default, currency, and volatility swaps.

Swap contracts are reported on a schedule following the Statement of Investments. The values of centrally cleared swap and OTC swap contracts are aggregated by positive and negative values and disclosed separately on the Statement of Assets and Liabilities in the annual and semiannual reports. The unrealized appreciation (depreciation) related to the change in the valuation of the notional amount of the swap is combined with the accrued interest due to (owed by) the Fund, if any, at termination or settlement. The net change in this amount during the period is included on the Statement of Operations in the annual and semiannual reports. The Fund also records any periodic payments received from (paid to) the counterparty, including at termination, under such contracts as realized gain (loss) on the Statement of Operations in the annual and semiannual reports.

Swap contract agreements are exposed to the market risk factor of the specific underlying reference rate or asset. Swap contracts are typically more attractively priced compared to similar investments in related cash securities because they isolate the risk to one market risk factor and eliminate the other market risk factors. Investments in cash securities (for instance bonds) have exposure to multiple risk factors (credit and interest rate risk). Because swaps have embedded leverage, they can expose the Fund to substantial risk in the isolated market risk factor.

Credit Default Swap Contracts. A credit default swap is a contract that enables an investor to buy or sell protection against a defined-issuer credit event, such as the issuer’s failure to make timely payments of interest or principal on a debt security, bankruptcy or restructuring. The Fund may enter into credit default swaps either by buying or selling protection on a corporate issuer, sovereign issuer, or a basket or index of issuers (the “reference asset”).

The buyer of protection pays a periodic fee to the seller of protection based on the notional amount of the swap contract. The seller of protection agrees to compensate the

17        OPPENHEIMER GLOBAL UNCONSTRAINED BOND FUND

NOTES TO STATEMENT OF INVESTMENTS Unaudited / Continued

6. Use of Derivatives (Continued)

buyer of protection for future potential losses as a result of a credit event on the reference asset. The contract effectively transfers the credit event risk of the reference asset from the buyer of protection to the seller of protection.

The ongoing value of the contract will fluctuate throughout the term of the contract based primarily on the credit risk of the reference asset. If the credit quality of the reference asset improves relative to the credit quality at contract initiation, the buyer of protection may have an unrealized loss greater than the anticipated periodic fee owed. This unrealized loss would be the result of current credit protection being cheaper than the cost of credit protection at contract initiation. If the buyer elects to terminate the contract prior to its maturity, and there has been no credit event, this unrealized loss will become realized. If the contract is held to maturity, and there has been no credit event, the realized loss will be equal to the periodic fee paid over the life of the contract.

If there is a credit event, the buyer of protection can exercise its rights under the contract and receive a payment from the seller of protection equal to the notional amount of the swap less the market value of specified debt securities issued by the reference asset. Upon exercise of the contract the difference between such value and the notional amount is recorded as realized gain (loss) and is included on the Statement of Operations in the annual and semiannual reports.

The Fund may purchase or sell credit protection through credit default swaps to increase or decrease exposure to the credit risk of individual issuers and/or indexes of issuers that are either unavailable or considered to be less attractive in the bond market.

For the reporting period, the Fund had ending monthly average notional amounts of $375,000 on credit default swaps to buy protection.

Additional associated risks to the Fund include counterparty credit risk and liquidity risk.

Interest Rate Swap Contracts. An interest rate swap is an agreement between counterparties to exchange periodic payments based on interest rates. One cash flow stream will typically be a floating rate payment based upon a specified floating interest rate while the other is typically a fixed interest rate.

The Fund may enter into interest rate swaps in which it pays the fixed or floating interest rate in order to increase or decrease exposure to interest rate risk. Typically, if relative interest rates rise, floating payments under a swap agreement will be greater than the fixed payments.

For the reporting period, the Fund had ending monthly average notional amounts of $3,748,600 and $6,032,725 on interest rate swaps which pay a fixed rate and interest rate swaps which receive a fixed rate, respectively.

Additional associated risks to the Fund include counterparty credit risk and liquidity risk.

Swaption Transactions

The Fund may enter into a swaption contract which grants the purchaser the right, but not the obligation, to enter into a swap transaction at preset terms detailed in the underlying agreement within a specified period of time. The purchaser pays a premium to the swaption writer who bears the risk of unfavorable changes in the preset terms on the underlying swap.

18        OPPENHEIMER GLOBAL UNCONSTRAINED BOND FUND

6. Use of Derivatives (Continued)

Purchased swaptions are reported as a component of investments in the Statement of Investments and the Statement of Assets and Liabilities in the annual and semiannual reports. Written swaptions are reported on a schedule following the Statement of Investments and their value is reported as a separate asset or liability line item in the Statement of Assets and Liabilities in the annual and semiannual reports. The net change in unrealized appreciation or depreciation on written swaptions is separately reported in the Statement of Operations in the annual and semiannual reports. When a swaption is exercised, the cost of the swap is adjusted by the amount of premium paid or received. Upon the expiration or closing of an unexercised swaption contract, a gain or loss is reported in the Statement of Operations in the annual and semiannual reports for the amount of the premium paid or received.

The Fund generally will incur a greater risk when it writes a swaption than when it purchases a swaption. When the Fund writes a swaption it will become obligated, upon exercise of the swaption, according to the terms of the underlying agreement. Swaption contracts written by the Fund do not give rise to counterparty credit risk prior to exercise as they obligate the Fund, not its counterparty, to perform. When the Fund purchases a swaption it only risks losing the amount of the premium it paid if the swaption expires unexercised. However, when the Fund exercises a purchased swaption there is a risk that the counterparty will fail to perform or otherwise default on its obligations under the swaption contract.

The Fund may purchase swaptions which give it the option to enter into an interest rate swap in which it pays a floating or fixed interest rate and receives a fixed or floating interest rate in order to increase or decrease exposure to interest rate risk. Purchasing the fixed portion of this swaption becomes more valuable as the reference interest rate decreases relative to the preset interest rate. Purchasing the floating portion of this swaption becomes more valuable as the reference interest rate increases relative to the preset interest rate.

The Fund may write swaptions which give it the obligation, if exercised by the purchaser, to enter into an interest rate swap in which it pays a fixed or floating interest rate and receives a floating or fixed interest rate in order to increase or decrease exposure to interest rate risk. A written swaption paying a fixed rate becomes more valuable as the reference interest rate increases relative to the preset interest rate. A written swaption paying a floating rate becomes more valuable as the reference interest rate decreases relative to the preset interest rate.

The Fund may write swaptions which give it the obligation, if exercised by the purchaser, to sell or buy credit protection through credit default swaps in order to increase or decrease exposure to the credit risk of individual issuers and/or indexes of issuers. A written swaption selling protection becomes more valuable as the likelihood of a credit event on the reference asset decreases. A written swaption buying protection becomes more valuable as the likelihood of a credit event on the reference asset increases.

During the reporting period, the Fund had an ending monthly average market value of $87,316 and $75,482 on purchased and written swaptions, respectively.

Counterparty Credit Risk. Derivative positions are subject to the risk that the counterparty will not fulfill its obligation to the Fund. The Fund intends to enter into derivative transactions

19        OPPENHEIMER GLOBAL UNCONSTRAINED BOND FUND

NOTES TO STATEMENT OF INVESTMENTS Unaudited / Continued

6. Use of Derivatives (Continued)

with counterparties that the Manager believes to be creditworthy at the time of the transaction.

The Fund’s risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund. For OTC options purchased, the Fund bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by the Fund should the counterparty fail to perform under the contracts. Options written by the Fund do not typically give rise to counterparty credit risk, as options written generally obligate the Fund and not the counterparty to perform.

To reduce counterparty risk with respect to OTC transactions, the Fund has entered into master netting arrangements, established within the Fund’s International Swap and Derivatives Association, Inc. (“ISDA”) master agreements, which allow the Fund to make (or to have an entitlement to receive) a single net payment in the event of default (close-out netting) for outstanding payables and receivables with respect to certain OTC positions in swaps, options, swaptions, and forward currency exchange contracts for each individual counterparty. In addition, the Fund may require that certain counterparties post cash and/or securities in collateral accounts to cover their net payment obligations for those derivative contracts subject to ISDA master agreements. If the counterparty fails to perform under these contracts and agreements, the cash and/or securities will be made available to the Fund.

ISDA master agreements include credit related contingent features which allow counterparties to OTC derivatives to terminate derivative contracts prior to maturity in the event that, for example, the Fund’s net assets decline by a stated percentage or the Fund fails to meet the terms of its ISDA master agreements, which would cause the Fund to accelerate payment of any net liability owed to the counterparty.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities in the annual and semiannual reports. Bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events.

The Fund’s risk of loss from counterparty credit risk on exchange-traded derivatives cleared through a clearinghouse and for centrally cleared swaps is generally considered lower than as compared to OTC derivatives. However, counterparty credit risk exists with respect to initial and variation margin deposited/paid by the Fund that is held in futures commission merchant, broker and/or clearinghouse accounts for such exchange-traded derivatives and for centrally cleared swaps.

With respect to centrally cleared swaps, such transactions will be submitted for clearing, and if cleared, will be held in accounts at futures commission merchants or brokers that are members of clearinghouses. While brokers, futures commission merchants and clearinghouses are required to segregate customer margin from their own assets, in the event that a broker, futures commission merchant or clearinghouse becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker, futures commission merchant or clearinghouse for all its customers, U.S. bankruptcy laws will

20        OPPENHEIMER GLOBAL UNCONSTRAINED BOND FUND

6. Use of Derivatives (Continued)

typically allocate that shortfall on a pro-rata basis across all the broker’s, futures commission merchant’s or clearinghouse’s customers, potentially resulting in losses to the Fund.

There is the risk that a broker, futures commission merchant or clearinghouse will decline to clear a transaction on the Fund’s behalf, and the Fund may be required to pay a termination fee to the executing broker with whom the Fund initially enters into the transaction. Clearinghouses may also be permitted to terminate centrally cleared swaps at any time. The Fund is also subject to the risk that the broker or futures commission merchant will improperly use the Fund’s assets deposited/paid as initial or variation margin to satisfy payment obligations of another customer. In the event of a default by another customer of the broker or futures commission merchant, the Fund might not receive its variation margin payments from the clearinghouse, due to the manner in which variation margin payments are aggregated for all customers of the broker/futures commission merchant.

Collateral and margin requirements differ by type of derivative. Margin requirements are established by the broker, futures commission merchant or clearinghouse for exchange-traded and cleared derivatives, including centrally cleared swaps. Brokers, futures commission merchants and clearinghouses can ask for margin in excess of the regulatory minimum, or increase the margin amount, in certain circumstances.

Collateral terms are contract specific for OTC derivatives. For derivatives traded under an ISDA master agreement, the collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of any collateral currently pledged by the Fund or the counterparty.

For financial reporting purposes, cash collateral that has been pledged to cover obligations of the Fund, if any, is reported separately on the Statement of Assets and Liabilities in the annual and semiannual reports as cash pledged as collateral. Non-cash collateral pledged by the Fund, if any, is noted in the Statement of Investments. Generally, the amount of collateral due from or to a party must exceed a minimum transfer amount threshold (e.g. $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance.

NOTES TO STATEMENT OF INVESTMENTSMarch 31, 2018 Unaudited

1. Organization

Oppenheimer Preferred Securities and Income Fund (the “Fund”), is a separate fund of Oppenheimer Integrity Funds, a diversified open-end management investment company registered under the Investment Company Act of 1940 (“1940 Act”), as amended. The Fund’s investment objective is to seek total return. The Fund’s investment adviser is OFI Global Asset Management, Inc. (“OFI Global” or the “Manager”), a wholly-owned subsidiary of OppenheimerFunds, Inc. (“OFI” or the “Sub-Adviser”). The Manager has entered into a sub-advisory agreement with OFI. The Fund commenced operations on February 12, 2018.

2. Securities Valuation

The Fund calculates the net asset value of its shares as of 4:00 P.M. Eastern Time, on each day the New York Stock Exchange (the “Exchange”) is open for trading, except in the case of a scheduled early closing of the Exchange, in which case the Fund will calculate net asset value of the shares as of the scheduled early closing time of the Exchange.

The Fund’s Board has adopted procedures for the valuation of the Fund’s securities and has delegated the day-to-day responsibility for valuation determinations under those procedures to the Manager. The Manager has established a Valuation Committee which is responsible for determining a fair valuation for any security for which market quotations are not readily available. The Valuation Committee’s fair valuation determinations are subject to review, approval and ratification by the Fund’s Board at least quarterly or more frequently, if necessary.

Valuation Methods and Inputs

Securities are valued primarily using unadjusted quoted market prices, when available, as supplied by third party pricing services or broker-dealers.

The following methodologies are used to determine the market value or the fair value of the types of securities described below:

Equity securities traded on a securities exchange (including exchange-traded derivatives other than futures and futures options) are valued based on the official closing price on the principal exchange on which the security is traded, as identified by the Manager, prior to the time when the Fund’s assets are valued. If the official closing price is unavailable, the security is valued at the last sale price on the principal exchange on which it is traded, or if no sales occurred, the security is valued at the mean between the quoted bid and asked prices. Over-the-counter equity securities are valued at the last published sale price, or if no sales occurred, at the mean between the quoted bid and asked prices. Events occurring after the close of trading on foreign exchanges may result in adjustments to the valuation of foreign securities to more accurately reflect their fair value as of the time when the Fund’s assets are valued.

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

Corporate and government debt securities (of U.S. or foreign issuers) and municipal debt securities, short-term notes, mortgage-backed securities, collateralized mortgage obligations, and asset-backed securities are valued at the mean between the bid and asked prices utilizing

NOTES TO STATEMENT OF INVESTMENTSUnaudited / Continued

2. Securities Valuation (Continued)

evaluated prices obtained from third party pricing services or broker-dealers who may use matrix pricing methods to determine the evaluated prices. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, sometimes at lower prices than institutional round lot trades. Standard inputs generally considered by third-party pricing vendors include reported trade data, broker-dealer price quotations, benchmark yields, issuer spreads on comparable securities, the credit quality, yield, maturity, as well as other appropriate factors.

Securities for which market quotations are not readily available, or when a significant event has occurred that would materially affect the value of the security, are fair valued either (i) by a standardized fair valuation methodology applicable to the security type or the significant event as previously approved by the Valuation Committee and the Fund’s Board or (ii) as determined in good faith by the Manager’s Valuation Committee. The Valuation Committee considers all relevant facts that are reasonably available, through either public information or information available to the Manager, when determining the fair value of a security. Those standardized fair valuation methodologies include, but are not limited to, valuing securities at the last sale price or initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be further adjusted for any discounts related to security-specific resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted quoted prices of similar securities, observable interest rates, currency rates and yield curves. The methodologies used for valuing securities are not necessarily an indication of the risks associated with investing in those securities nor can it be assured that the Fund can obtain the fair value assigned to a security if it were to sell the security.

Classifications

Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Various data inputs may be used in determining the value of each of the Fund’s investments as of the reporting period end.

These data inputs are categorized in the following hierarchy under applicable financial accounting standards:

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

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

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

The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

The Fund classifies each of its investments in investment companies which are publicly

offered as Level 1. Investment companies that are not publicly offered, if any, are classified as Level 2 in the fair value hierarchy.

The table below categorizes amounts at period end based on valuation input level:

Forward currency exchange contracts and futures contracts, if any, are reported at their unrealized appreciation/depreciation at measurement date, which represents the change in the contract’s value from trade date. All additional assets and liabilities included in the above table are reported at their market value at measurement date.

3. Investments and Risks

Investments in Affiliated Funds. The Fund is permitted to invest in other mutual funds advised by the Manager (“Affiliated Funds”). Affiliated Funds are open-end management investment companies registered under the 1940 Act, as amended. The Manager is the investment adviser of, and the Sub-Adviser provides investment and related advisory services to, the Affiliated Funds. When applicable, the Fund’s investments in Affiliated Funds are included in the Statement of Investments. Shares of Affiliated Funds are valued at their net asset value per share. As a shareholder, the Fund is subject to its proportional share of the Affiliated Funds’ expenses, including their management fee. The Manager will waive fees and/ or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund’s investment in the Affiliated Funds.

Each of the Affiliated Funds in which the Fund invests has its own investment risks, and those risks can affect the value of the Fund’s investments and therefore the value of the Fund’s shares. To the extent that the Fund invests more of its assets in one Affiliated Fund than in another, the Fund will have greater exposure to the risks of that Affiliated Fund.

Investments in Money Market Instruments. The Fund is permitted to invest its free cash balances in money market instruments to provide liquidity or for defensive purposes. The Fund may invest in money market instruments by investing in Class E shares of Oppenheimer Institutional Government Money Market Fund (“IGMMF”), which is an Affiliated Fund. IGMMF is regulated as a money market fund under the 1940 Act, as amended. The Fund may also invest in money market instruments directly or in other affiliated or unaffiliated money market

3. Investments and Risks (Continued)

funds.

Equity Security Risk. Stocks and other equity securities fluctuate in price. The value of the Fund’s portfolio may be affected by changes in the equity markets generally. Equity markets may experience significant short-term volatility and may fall sharply at times. Different markets may behave differently from each other and U.S. equity markets may move in the opposite direction from one or more foreign stock markets. Adverse events in any part of the equity or fixed-income markets may have unexpected negative effects on other market segments.

The prices of individual equity securities generally do not all move in the same direction at the same time and a variety of factors can affect the price of a particular company’s securities. These factors may include, but are not limited to, poor earnings reports, a loss of customers, litigation against the company, general unfavorable performance of the company’s sector or industry, or changes in government regulations affecting the company or its industry.

4. Market Risk Factors

The Fund’s investments in securities and/or financial derivatives may expose the Fund to various market risk factors:

Commodity Risk. Commodity risk relates to the change in value of commodities or commodity indexes as they relate to increases or decreases in the commodities market. Commodities are physical assets that have tangible properties. Examples of these types of assets are crude oil, heating oil, metals, livestock, and agricultural products.

Credit Risk. Credit risk relates to the ability of the issuer of debt to meet interest and principal payments, or both, as they come due. In general, lower-grade, higher-yield debt securities are subject to credit risk to a greater extent than lower-yield, higher-quality securities.

Equity Risk. Equity risk relates to the change in value of equity securities as they relate to increases or decreases in the general market.

Foreign Exchange Rate Risk. Foreign exchange rate risk relates to the change in the U.S. dollar value of a security held that is denominated in a foreign currency. The U.S. dollar value of a foreign currency denominated security will decrease as the dollar appreciates against the currency, while the U.S. dollar value will increase as the dollar depreciates against the currency.

Interest Rate Risk. Interest rate risk refers to the fluctuations in value of fixed-income securities resulting from the inverse relationship between price and yield. For example, an increase in general interest rates will tend to reduce the market value of already issued fixed-income investments, and a decline in general interest rates will tend to increase their value. In addition, debt securities with longer maturities, which tend to have higher yields, are subject to potentially greater fluctuations in value from changes in interest rates than obligations with shorter maturities.

Volatility Risk. Volatility risk refers to the magnitude of the movement, but not the direction of the movement, in a financial instrument’s price over a defined time period.

8      OPPENHEIMER PREFERRED SECURITIES AND INCOME FUND

4. Market Risk Factors (Continued)

Large increases or decreases in a financial instrument’s price over a relative time period typically indicate greater volatility risk, while small increases or decreases in its price typically indicate lower volatility risk.

Item 2. Controls and Procedures.

(a) 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 3/31/2018, 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 the 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.

(b) There have been no significant changes in the registrant’s internal controls over financial reporting that occurred during the registrant’s last fiscal quarter that has materially affected, or is reasonably likely to materially affect, the registrant’s internal control over financial reporting.
