Fund Performance Discussion

MARKET OVERVIEW

The U.S. economy continued to perform well during the reporting period. U.S. 2018 gross domestic product (GDP) increased at an estimated 4.2% annualized rate over the second quarter of 2018, significantly exceeding its 2% trend growth of this expansion. Private consumption, the driving force of the economy in recent years, is growing at a stable rate. Additionally, business fixed investment has gained momentum in recent months and is broadening across sectors. With increasingly less slack in the economy, strong profits, and the corporate tax cuts, we believe investment should support growth and productivity improvements.

The Federal Reserve (Fed) hiked the Fed Funds target rate by 25 basis points twice – in March and June – ending the period in a range of 1.75% - 2.00%. The Fed is on track to deliver 1-2 more hikes this year, as the economy is near the Fed’s dual mandate of full employment and price stability. On the inflation front, underlying inflation is around the Fed’s 2% target. The unemployment rate is at historical lows; however, the rising labor participation rate and stable wage growth suggest that there may still be some slack in the labor market. The Federal Open Market Committee (FOMC) under new chair Jerome Powell’s leadership signaled that the Fed will remain cautious and tighten policy gradually,

giving comfort to the markets. Thus far, the Fed’s hiking cycle has been orderly.

Despite the strength of the U.S. economy and the Fed’s orderly hiking cycle, international economic and geopolitical concerns were noticeable during the reporting period and caused some market turbulence. Trade tensions were on the rise and there were pockets of political issues. Such tensions, especially regarding trade, made an impact on some investment decisions, as noted in the Fed’s minutes. So far, the measures implemented are not of major economic significance, in our view. At this point, we believe there is more rhetoric than actual impactful decisions. The risk remains, however, that trade issues hit confidence or that retaliations could lead to more significant measures. While these are still not the baseline, risks are elevated and worth carefully monitoring.

In this environment, markets were volatile this reporting period. Equity markets in the U.S. produced positive results and outperformed international equities, with the S&P 500 Index returning 16.24% and the MSCI All Country

World Index returning 10.97%. In fixed income markets, the Bloomberg Barclays U.S. Aggregate Bond Index produced a -0.80% return. Credit slightly outperformed for the

reporting period, with the Bloomberg Barclays Credit Index returning -0.66%.

FUND REVIEW

Against this backdrop, the Fund’s Class A shares (without sales charge) produced a return of -1.67% this reporting period, underperforming the Bloomberg Barclays U.S. Aggregate Bond Index’s (the “Index”) return of -0.80%.

The primary detractors from performance included security selection within the banking and technology sectors. Top contributors to the Fund’s performance included security selection within consumer cyclical and energy. Also contributing was the Fund’s allocation to high yield credit.

STRATEGY & OUTLOOK

We believe macroeconomic fundamentals should remain solid with a potential increase in U.S. growth due to the stimulus package and tax reform. We believe the Fed may raise interest rates two more times this year depending on economic data after the most recent increase in June.

We remain cautiously engaged in investment-grade corporate credit with modest exposure to typically high Sharpe Ratio BB-rated corporates. As a result, we continue to be less likely to meaningfully increase credit risk,

absent specific relative value opportunities. We typically avoid B-rated and below high yield corporate bonds.

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. Returns do not consider capital gains or income taxes on an individual’s investment. For performance data current to the most recent month-end, visit oppenheimerfunds.com or call 1.800. CALL OPP (225.5677). 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 C shares, the contingent deferred sales charge of 1% for the 1-year period. There is no sales charge for Class I, Class R and Class Y shares. Returns for periods of less than one year are cumulative and not annualized. See Fund prospectuses and summary prospectuses for more information on share classes and sales charges .

Standardized yield is based on an SEC-standardized formula designed to approximate the Fund’s annualized hypothetical current income from securities less expenses for the 30-day period ended July 31, 2018 and that date’s maximum offering price (for Class A shares) or net asset value (for all other share classes). Each result is compounded semiannually and then annualized. Falling share prices will tend to artificially raise yields. The unsubsidized

7 OPPENHEIMER CORPORATE BOND FUND

standardized yield is computed under an SEC-standardized formula based on net income earned for the 30-day period ended July 31, 2018. The calculation excludes any expense reimbursements and thus may result in a lower yield.

The Bloomberg Barclays U.S. Aggregate Bond Index is an index of U.S dollar-denominated, investment-grade U.S. corporate government and mortgage-backed securities. The Index is unmanaged and cannot be purchased directly by investors. 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 comprising the Index. Index performance includes reinvestment of income, but does not reflect transaction costs, fees, expenses or taxes. Index performance is shown for illustrative purposes only as a benchmark for the Fund’s performance, and does not predict or depict performance of the Fund. The Fund’s performance reflects the effects of the Fund’s business and operating expenses.

The views in the Fund Performance Discussion represent the opinions of this Fund’s portfolio manager(s) and are not intended as investment advice or to predict or depict the performance of any investment. These views are as of the close of business on July 31, 2018, and are subject to change based on subsequent developments. The Fund’s portfolio and strategies are subject to change.

Before investing in any of the Oppenheimer funds, investors should carefully consider a fund’s investment objectives, risks, charges and expenses. Fund prospectuses and summary prospectuses contain this and other information about the funds, and may be obtained by asking your financial advisor, visiting oppenheimerfunds.com, or calling 1.800.CALL OPP (225.5677). Read prospectuses and summary prospectuses carefully before investing.

Shares of Oppenheimer funds are not deposits or obligations of any bank, are not guaranteed by any bank, are not insured by the FDIC or any other agency, and involve investment risks, including the possible loss of the principal amount invested.

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 and/or contingent deferred sales charges on redemptions; 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 July 31, 2018.

Actual Expenses. The first section of the table provides information about actual account values and actual expenses. You may use the information in this section for the class of shares you hold, together with the amount you invested, to estimate the expense that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00 = 8.60), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During 6 Months Ended July 31, 2018” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes. The second section of the table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio for each class of shares, and an assumed rate of return of 5% per year for each class before expenses, which is not the 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). Therefore, the “hypothetical” section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Class R	1,000.00	1,018.89	5.97
Class Y	1,000.00	1,021.37	3.46

Expenses are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period). Those annualized expense ratios, excluding indirect expenses from affiliated funds, based on the 6-month period ended July 31, 2018 are as follows:


Class	Expense Ratios
Class A		0.93%
Class C		1.69
Class I		0.55
Class R		1.19
Class Y		0.69

The expense ratios reflect voluntary and/or contractual waivers and/or reimbursements of expenses by the Fund’s Manager and Transfer Agent. Some of these undertakings may be modified or terminated at any time, as indicated in the Fund’s prospectus. The “Financial Highlights” tables in the Fund’s financial statements, included in this report, also show the gross expense ratios, without such waivers or reimbursements and reduction to custodian expenses, if applicable.

34 OPPENHEIMER CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS July 31, 2018

1. Organization

Oppenheimer Corporate Bond Fund (the “Fund”) is registered under the Investment Company Act of 1940 (“1940 Act”), as amended, as an open-end diversified management investment company. 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 offers Class A, Class C, Class I, Class R 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 C and Class R shares are sold without a front-end sales charge but may be subject to a contingent deferred sales charge (“CDSC”). Class R shares are sold only through retirement plans. Retirement plans that offer Class R shares may impose charges on those accounts. Class I and Class Y shares are sold to certain institutional investors or intermediaries without either a front-end sales charge or a CDSC, however, the intermediaries may impose charges on their accountholders who beneficially own Class I and Class Y shares. 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, C and R shares have separate distribution and/or service plans under which they pay fees. Class I and Class Y shares do not pay such fees.

The following is a summary of significant accounting policies followed in the Fund’s preparation of financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”).

2. Significant Accounting Policies

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

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.

Dividends and Distributions to Shareholders. Dividends and distributions to shareholders, which are determined in accordance with income tax regulations and may differ from U.S. GAAP, 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 or at other times as determined necessary by the Manager.

Investment Income. Dividend income is recorded on the ex-dividend date or upon

35 OPPENHEIMER CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS Continued

2. Significant Accounting Policies (Continued)

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 value of the securities received. Withholding taxes on foreign dividends, if any, and capital gains taxes on foreign investments, if any, have been provided for in accordance with the Fund’s understanding of the applicable tax rules and regulations. Interest income, if any, is recognized on an accrual basis. Discount and premium, which are included in interest income on the Statement of Operations, are amortized or accreted daily.

Custodian Fees. “Custodian fees and expenses” in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdrafts, to the extent they are not offset by positive cash balances maintained by the Fund, at a rate equal to the Federal Funds Rate plus 2.00%. The “Reduction to custodian expenses” line item, if applicable, represents earnings on cash balances maintained by the Fund during the period. Such interest expense and other custodian fees may be paid with these earnings.

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

Indemnifications. The Fund’s organizational documents provide current and former Trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund’s maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

Federal Taxes. The Fund intends to comply with provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its investment company taxable income, including any net realized gain on investments not offset by capital loss carryforwards, if any, to shareholders. Therefore, no federal income or excise tax provision is required. The Fund files income tax returns in U.S. federal and applicable state jurisdictions. The statute of limitations on the Fund’s tax return filings generally remains open for the three preceding fiscal reporting period ends. The Fund has analyzed its tax positions for the fiscal year ended July 31, 2018, including open tax years, and does not believe there are any uncertain tax positions requiring recognition in the Fund’s financial statements.

The tax components of capital shown in the following table 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.

2. Significant Accounting Policies (Continued)


Undistributed Net Investment Income	Undistributed Long-Term Gain		Accumulated Loss Carryforward ^1,2,3		Net Unrealized Depreciation Based on cost of Securities and Other Investments for Federal Income Tax Purposes
$110,613		$—		$2,810,210		$3,656,756

1. At period end, the Fund had $2,810,210 of net capital loss carryforward available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions.

2. During the reporting period, the Fund did not utilize any capital loss carryforward.

3. During the previous reporting period, the Fund utilized $2,161,432 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 are determined in accordance with federal income tax requirements, which may differ from the character of net investment income or net realized gains presented in those financial statements in accordance with U.S. GAAP. 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 the reporting period. Net assets of the Fund were unaffected by the reclassifications.

The aggregate cost of securities and other investments and the composition of unrealized appreciation and depreciation of securities and other investments for federal income tax purposes at period end are noted in the following table. The primary difference between book and tax appreciation or depreciation of securities and other investments, if applicable, is attributable to the tax deferral of losses or tax realization of financial statement unrealized gain or loss.

Federal tax cost of securities	$	207,007,374
Federal tax cost of other investments		(85,812,001)

Gross unrealized appreciation	$	1,535,942
Gross unrealized depreciation		(5,192,698)

Net unrealized depreciation	$	(3,656,756)

Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

New Accounting Pronouncement. In March 2017, Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”), ASU 2017-08. This provides guidance related to the amortization period for certain purchased callable debt securities held at a premium. The ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. The Manager is evaluating the impacts of these changes on the financial statements .

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

38 OPPENHEIMER CORPORATE BOND FUND

3. Securities Valuation (Continued)

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, 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.

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 that are included in the Fund’s Statement of Assets and Liabilities at period end based on valuation input level:

4. 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

40 OPPENHEIMER CORPORATE BOND FUND

4. Investments and Risks (Continued)

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 as follows:


	When-Issued or Delayed Delivery Basis Transactions
Purchased securities		$ 633,100

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

NOTES TO FINANCIAL STATEMENTS Continued

4. Investments and Risks (Continued)

securities are reported on a schedule following the Statement of Investments.

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 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

42 OPPENHEIMER CORPORATE BOND FUND

6. Use of Derivatives (Continued)

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.

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

43 OPPENHEIMER CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS Continued

6. Use of Derivatives (Continued)

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 $47,897,404 and $57,161,872 on futures contracts purchased and sold, respectively.

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.

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. 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. 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.

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

44 OPPENHEIMER CORPORATE BOND FUND

6. Use of Derivatives (Continued)

“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 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.

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 $694,231 on credit default swaps to sell protection.

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

At period end, the Fund had no credit default swap agreements outstanding.

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.

Purchased swaptions are reported as a component of investments in the Statement of Investments and the Statement of Assets and Liabilities. 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. The net change in unrealized appreciation or depreciation on written swaptions is separately reported in the Statement of Operations. 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 for the amount of the premium paid or received.

45 OPPENHEIMER CORPORATE BOND FUND

NOTES TO FINANCIAL STATEMENTS Continued

6. Use of Derivatives (Continued)

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 buy or sell credit protection through credit default swaps in order to decrease or increase exposure to the credit risk of individual issuers and/ or indexes of issuers. A swaption selling protection becomes more valuable as the likelihood of a credit event on the reference asset decreases. A swaption buying protection becomes more valuable as the likelihood of a credit event on the reference asset increases.

At period end, the Fund had no purchased swaption contracts outstanding.

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 $1,919 and $862 on purchased and written swaptions, respectively.

At period end, the Fund had no written swaption contracts outstanding.

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. 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

46 OPPENHEIMER CORPORATE BOND FUND

6. Use of Derivatives (Continued)

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 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 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.

9. Fees and Other Transactions with Affiliates

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


Fee Schedule
Up to $500 million	0.45	%
Next $500 million	0.40
Next $4 billion	0.35
Over $5 billion	0.30

The Fund’s effective management fee for the reporting period was 0.45% of average annual net assets before any applicable waivers.

Sub-Adviser Fees. The Manager has retained the Sub-Adviser to provide the day-to-day portfolio management of the Fund. Under the Sub-Advisory Agreement, the Manager pays the Sub-Adviser an annual fee in monthly installments, equal to a percentage of the investment management fee collected by the Manager from the Fund, which shall be calculated after any investment management fee waivers. The fee paid to the Sub-Adviser is paid by the Manager, not by the Fund.

Transfer Agent Fees. OFI Global (the “Transfer Agent”) serves as the transfer and shareholder servicing agent for the Fund. The Fund pays the Transfer Agent a fee based on annual net assets, which shall be calculated after any applicable fee waivers. Fees incurred and

average net assets for each class with respect to these services are detailed in the Statement of Operations and Financial Highlights, respectively.

Sub-Transfer Agent Fees. The Transfer Agent has retained Shareholder Services, Inc., a wholly-owned subsidiary of OFI (the “Sub-Transfer Agent”), to provide the day-to-day transfer agent and shareholder servicing of the Fund. Under the Sub-Transfer Agency Agreement, the Transfer Agent pays the Sub-Transfer Agent an annual fee in monthly installments, equal to a percentage of the transfer agent fee collected by the Transfer Agent from the Fund, which shall be calculated after any applicable fee waivers. The fee paid to the Sub-Transfer Agent is paid by the Transfer Agent, not by the Fund.

Trustees’ Compensation. The Fund’s Board of Trustees (“Board”) has adopted a compensation deferral plan for Independent Trustees that enables Trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from the Fund. For purposes of determining the amount owed to the Trustees 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 Trustees. The Fund purchases shares of the funds selected for deferral by the Trustees 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 with the compensation deferral plan.

Distribution and Service Plan (12b-1) Fees. Under its General Distributor’s Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the “Distributor”) acts as the Fund’s principal underwriter in the continuous public offering of the Fund’s classes of shares.

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

Distribution and Service Plans for Class C and Class R Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class C and Class R shares pursuant to Rule 12b-1 under the 1940 Act to compensate the Distributor for distributing those share classes,

maintaining accounts and providing shareholder services. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class C shares’ daily net assets and 0.25% on Class R shares’ daily net assets. The Fund also pays a service fee under the Plans at an annual rate of 0.25% of daily net assets. The Plans continue in effect from year to year only if the Fund’s Board of Trustees votes annually to approve their continuance at an in person meeting called for that purpose. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations.

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

Waivers and Reimbursements of Expenses. Effective for the period January 1, 2017 through December 31, 2017, the Transfer Agent voluntarily waived and/or reimbursed Fund expenses in an amount equal to 0.015% of average annual net assets for Classes A, C, R and Y.

Class A	$	8,375

During the reporting period, the Manager waived fees and/or reimbursed the Fund $34,622 for these management fees. This fee waiver and/or expense reimbursement may not be amended or withdrawn for one year from the date of the Fund’s prospectus, unless approved by the Board.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees

Oppenheimer Corporate Bond Fund :

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Oppenheimer Corporate Bond Fund (the “Fund”), including the statement of investments, as of July 31, 2018, the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two year period then ended, and the related notes (collectively, the “financial statements”) and the financial highlights for each of the years in the five year period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of July 31, 2018, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two year period then ended, and the financial highlights for each of the years in the five year period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

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 are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. 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, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of July 31, 2018, by correspondence with the custodian, brokers and the transfer agent, or by other appropriate auditing procedures. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

KPMG _LLP

We have not been able to determine the specific year that we began serving as the auditor of one or more Oppenheimer Funds investment companies, however we are aware that we have served as the auditor of one or more Oppenheimer Funds investment companies since at least 1969.

FEDERAL INCOME TAX INFORMATION Unaudited

In early 2018, if applicable, shareholders of record received information regarding all dividends and distributions paid to them by the Fund during calendar year 2017.

None of the dividends paid by the Fund during the reporting period are eligible for the corporate dividend-received deduction.

Dividends, if any, paid by the Fund during the reporting period which are not designated as capital gain distributions, may be eligible for lower individual income tax rates to the extent that the Fund has received qualified dividend income as stipulated by recent tax legislation. In early 2018, shareholders of record received information regarding the percentage of distributions that are eligible for lower individual income tax rates. The amount will be the maximum amount allowed.

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 reporting period, the maximum amount allowable but not less than $4,774,786 of the ordinary distributions to be paid by the Fund qualifies as an interest related dividend.

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.

Householding—Delivery of Shareholder Documents

This is to inform you about OppenheimerFunds’ “householding” policy. If more than one member of your household maintains an account in a particular fund, OppenheimerFunds will mail only one copy of the fund’s prospectus (or, if available, the fund’s summary prospectus), annual and semiannual report and privacy policy. The consolidation of these mailings, called householding, benefits your fund through reduced mailing expense, and benefits you by reducing the volume of mail you receive from OppenheimerFunds. Householding does not affect the delivery of your account statements.

Please note that we will continue to household these mailings for as long as you remain an OppenheimerFunds shareholder, unless you request otherwise. If you prefer to receive multiple copies of these materials, please call us at 1.800.CALL-OPP (225-5677). You may also notify us in writing or via email. We will begin sending you individual copies of the prospectus (or, if available, the summary prospectus), reports and privacy policy within 30 days of receiving your request to stop householding.

All transactions conducted via our websites, including redemptions, exchanges and purchases, are secured by the highest encryption standards available. SSL is used to establish a secure connection between your PC and OppenheimerFunds’ server. It transmits information in an encrypted and scrambled format.

Encryption is achieved through an electronic scrambling technology that uses a “key” to code and then decode the data. Encryption acts like the cable converter box you may have on your television set. It scrambles data with a secret code so that no one can make sense of it while it is being transmitted. When the data reaches its destination, the same software unscrambles the data.

Other Security Measures

We maintain physical, electronic and procedural safeguards to protect your personal account information. Our employees and agents have access to that information only so that they may offer you products or provide services, for example, when responding to your account questions.

How You Can Help

You can also do your part to keep your account information private and to prevent unauthorized transactions. If you obtain a user ID and password for your account, safeguard that information. Strengthening your online credentials–your online security profile–typically your user name, password, and security questions and answers, can be one of your most important lines of defense on the Internet.

CODE OF ETHICS FOR PRINCIPAL EXECUTIVE AND FINANCIAL OFFICERS OF THE OPPENHEIMER FUNDS, OPPENHEIMERFUNDS, INC., OFI GLOBAL ASSET MANAGEMENT, INC. AND OFI STEELPATH, INC.

This Code of Ethics for Principal Executive and Financial Officers (referred to in this document as the “Code”) has been adopted by each of the investment companies for which OppenheimerFunds, Inc. (“OFI”), OFI Global Asset Management, Inc. (“OFI Global”) , OFI SteelPath, Inc. (“OFI SteelPath”) or one of OFI’s other subsidiaries (referred to collectively in this document as “OFI”) acts as investment adviser (individually, a “Fund” and collectively, the “Funds”), and by OFI to effectuate compliance with Section 406 under the Sarbanes-Oxley Act of 2002 and the rules adopted to implement Section 406.

This Code applies to OFI’s and each Fund’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions (“Covered Officers”). A listing of positions currently within the ambit of Covered Officers is attached as Exhibit A . ¹

I NTRODUCTION / D EFINITION / P OLICY S TATEMENT :

In general, the principles that govern honest and ethical conduct, including the avoidance of conflicts of interest between personal and professional relationships, reflect, at the minimum, the following: (1) the duty at all times in performing any responsibilities as a Fund financial officer, controller, accountant or principal executive officer to place the interests of the Funds ahead of personal interests; (2) the fundamental standard that Covered Officers should not take inappropriate advantage of their positions; (3) the duty to assure that a Fund’s financial statements and reports to its shareholders are prepared honestly and accurately in accordance with applicable rules, regulations and accounting standards; and (4) the duty to conduct the Funds’ business and affairs in an honest and ethical manner. Each Covered Officer should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

It is acknowledged that, as a result of the contractual relationship between each Fund and OFI, of which the Covered Officers are also officers or employees, and subject to OFI’s fiduciary duties to each Fund, the Covered Officers may, in the normal course of their duties, be involved in establishing policies and implementing decisions that will have different effects on OFI and the Funds. It is further acknowledged that the participation of the Covered Officers in such activities is inherent in the contractual relationship between each Fund and OFI and is consistent with the expectations of the Board of Trustees/Directors of the performance by the Covered Officers of their duties as officers of the Funds.

The obligations imposed by this Code on Covered Officers are separate from and in addition to any obligations that may be imposed on such persons as Covered Persons under the Code of Ethics adopted by OFI and the Funds under Rule 17j-1 of the Investment Company Act of 1940, as amended and any other code of conduct applicable to Covered Officers in whatever capacity they serve. This Code does not incorporate by reference any provisions of the Rule 17j-1 Code of Ethics and accordingly, any violations or waivers granted under the Rule 17j-1 Code of Ethics will not be considered a violation or waiver under this Code.

P OLICY D ETAILS :

A.	POLICY STATEMENT

Overview . As a means of implementing Section 406 of SOX (“Section 406”), the SEC has adopted certain rules that require a mutual fund to disclose:

•

Whether or not it has adopted a code of ethics that applies to the mutual fund’s principal executive officer, principal financial officer, principal accounting officer, controller or any other person that performs similar functions (each a “Covered Officer” and, collectively, the “Covered Officers”);

•

Why, if it has not adopted such code, it has not done so; and

•

Amendments to, and waivers from, the code of ethics relating to any of the Covered Officers.

Section 406 defines a “code of ethics” to mean such standards as are reasonable necessary to promote:

•

Honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

•

Full, fair, accurate, timely and understandable disclosure in the periodic reports required to be filed by the issuer; and

•

Compliance with applicable laws, rules and regulations.

This Code of Ethics for Principal Executive and Financial Officers (the “Executive Code”) sets forth standards and procedures to ensure compliance with SOX Section 406 and shall apply to each Covered Officer of the Funds and ETF Trust (referred to herein as the “Funds”).

Honest and ethical conduct . This Executive Code is intended to assure that the behavior of Covered Officers does not put, or appear to put, the interests of other parties above those of the Funds and that conflicts of interest are identified and handled ethically. A conflict of interest occurs when a Covered Officer allows, or appears to allow, advantages that could otherwise be avoided or ameliorated, to other parties at the expense of a Fund. Such advantages may benefit a Covered Officer’s own private interests over the interests of the Funds. Conflicts of interest may also arise when, in addition to serving as a Covered Officer of the Funds, a Covered Officer also holds a position as an officer or employee of an investment adviser or other entity retained by a Fund. A conflict of interest may be created if a Covered Officer who also serves as an officer or employee of an investment adviser to the Funds, provides benefits to another party that are improper, or that are a breach of the Covered Officer’s fiduciary relationship to the Funds, if the benefit was derived from such Covered Officer’s position with the Funds.

The compliance programs and procedures of the Funds and the investment adviser(s) to the Funds are designed to prevent, or identify and correct, violations of provisions set forth in the Investment Company Act and the Investment Advisers Act, including certain conflict of interest provisions. The obligations imposed by this Executive Code on Covered Officers are separate and in addition to any obligations imposed on such persons under any other procedures, such as the Code of Ethics adopted by the Funds and the investment advisers to the Funds pursuant to Rule 17j-1 under the Investment Company Act. This Executive Code does not, and is not intended to, repeat or replace these programs and procedures. Violations of such other programs and procedures shall be addressed in accordance with the applicable program or procedure, unless or until it is determined that a violation of such program and procedure is also a violation of this Executive Code.

If a Covered Officer becomes aware of a conflict of interest or perceives there to be a conflict of interest, such Covered Officer shall promptly report the matter to the Funds’ Chief Compliance Officer or the OFI General Counsel. Upon receipt of a report, the Chief Compliance Officer or OFI General Counsel will take prompt steps to determine whether a conflict or perceived conflict of interest exists. If it is determined that an actual or perceived conflict of interest exists, the Chief Compliance Officer or OFI General Counsel will take steps to resolve the conflict or the appearance of a conflict. If it is determined that no conflict or appearance of a conflict exists, the Chief Compliance Officer or OFI General Counsel shall meet with the Covered Officer to advise him or her of such finding and of his or her reason for taking no action. In lieu of determining whether a conflict or appearance of conflict exists, the matter may be referred to the Funds’ Boards.

Prohibited Activity : No Covered Officer shall, in connection with carrying out his or her duties on behalf of the Funds:

•

Use information concerning business and affairs of the Funds, including the investment intentions of the Funds, for personal gain to himself or herself, his or her family or friends or any other person, or in a manner detrimental to the interests of the Funds or the shareholders of the Funds;

•

Use his or her ability to influence investment intentions for personal gain to himself or herself, his or her family or friends or any other person or in a manner detrimental to the Funds or the shareholders of the Funds;

•

Use his or her personal influence or personal relationships to influence the preparation and issuance of financial reports of a Fund whereby the Covered Officer would benefit personally to the detriment of Funds or the shareholders of the Funds;

•

Intentionally take any action or fail to take any action in connection with his or her official acts on behalf of the Funds that causes the Funds to violate applicable laws, rules and regulations;

•

Employ any device, scheme, artifice or manipulative practice to defraud the Funds or the shareholders of the Funds;

•

Intentionally cause the Funds to make any untrue statement of a material fact or omit to state a material fact that conflicts with statements made in official documents, regulatory filings, financial statements or communications to the public;

•

Intentionally cause the Funds to fail to comply with applicable laws, rules and regulations, including failure to comply with the requirement of full, fair, accurate, understandable and timely disclosure in reports and documents that the Funds file with, or submit to, the SEC and in other public communications;

•

Intentionally mislead or fail to provide material information to the independent auditors of the Funds or to the Board of Trustees/Directors or the officers of the Funds or their investment adviser(s) in connection with financial reporting matters;

•

Intentionally cause a Fund to be financially disadvantaged or to bear unwarranted expenses;

•

Retaliate against others for, or otherwise discourage the reporting of, actual or apparent violations of this Code.

Waivers . Covered Officers requesting a waiver of any of the provisions of the Executive Code must submit a written request for such waiver to the Compliance Department, setting forth the basis of such request and all necessary facts upon which such request can be evaluated.

The Compliance Department shall review such request and make a written determination thereon, which shall be binding. The Compliance Department may, in reviewing such request, consult in its discretion with legal counsel to the Funds, or the Board, if applicable.

In determining whether to waive any of the provisions of this Code, the Compliance Department shall consider whether the proposed waiver:

•

Is prohibited by this Executive Code;

•

Is consistent with honest and ethical conduct; and

•

Will result in a conflict of interest between the Covered Officer’s personal and professional obligations to a Fund.

For purposes of clarification, a determination by a Board as to the appropriate handling of a conflict of interest that has been disclosed to it and that does not involve unethical or fraudulent conduct does not constitute a waiver of this Executive Code.

Sanctions . Any violation of this Executive Code shall be subject to the imposition of such sanctions as may be deemed appropriate under the circumstances and may include, without limitation, a letter of censure, suspension from employment or termination of employment.

B.	POLICY IMPLEMENTATION

Each Covered Officer shall:

•

Certify that he or she has received, read and understands his or her obligations under the Executive Code (upon becoming subject to the Executive Code and annually thereafter); and

•

Includes the current Executive Code as an exhibit; and

•

Provides disclosure with respect to any waivers that have been granted under the Executive Code.

Amendments . At least annually, the Board of each Fund shall review the Executive Code and consider whether any amendments are necessary or desirable. Proposed amendments to the Executive Code shall be presented to the Boards for review and approval at such times other than the annual review as deemed necessary or desirable by the Chief Compliance Officer.
