Fund Performance Discussion

The Fund’s Class A shares (without sales charge) returned 3.84% during the one-year reporting period, underperforming the J.P. Morgan Leveraged Loan Index (the “Index”), which returned 4.79%.

MARKET HIGHLIGHTS

Riskier investments, such as stocks, continued to gain value over the second half of 2017 in an environment of positive global economic growth, rising corporate earnings, and expectations that more business-friendly regulatory, tax, and fiscal policies from the U.S. government would continue to support stock prices. At the same time, interest rates in most major markets climbed gradually as some major central banks shifted to less accommodative monetary policies when labor markets strengthened and inflationary pressures intensified. In the United States,

the Federal Reserve raised interest rates three times over this reporting period and began to unwind its balance sheet.

Heightened volatility returned to the financial markets over the first seven months of 2018. Although several broad measures of global and U.S. stock market performance set new record highs in January 2018, financial markets soon encountered renewed concerns stemming from inflationary pressures in the United States and growing concerns over a potential global trade war.

For the one-year period ended July 31, 2018, the J.P. Morgan Leveraged Loan Index returned 4.79% and continued to demonstrate less sensitivity to the increased volatility across equity and the broader fixed-income markets. In comparison, high yield, as represented by the J.P. Morgan Domestic High Yield Index, returned 1.18% as the high yield sector has experienced pressure due to swings in equities, fixed income and oil markets. For a period that has been characterized by rising Treasury rates and volatility, loans have performed well.

FUND REVIEW

The primary detractor from relative performance this period was security selection in the Retail sector, where a children’s apparel company filed for Chapter 11 bankruptcy in early 2018. It has since emerged from bankruptcy with a significantly de-leveraged balance sheet. We believe the potential recovery value is greater than its current market valuation and continue to maintain a position. Other detractors included security selection within the Automotive and Broadcasting sectors.

During the reporting period, the Fund experienced its strongest outperformance versus the Index in the Financial sector, where security selection benefited. A strong driver of performance in the Financial sector was a

registered investment advisory firm that has continued to see strong demand for its loans. Other top contributors included security selection in the Metals and Mining and Telecommunications sectors.

In addition, the Fund actively employs leverage to seek to enhance returns. During the reporting period, the use of leverage contributed positively to the total return of the Fund.

STRATEGY & OUTLOOK

At the end of the reporting period, relative to the Index, the Fund had modest overweights in the Broadcasting, Metals and Mining, and Automotive (parts suppliers) sectors and modest underweights in the Industrials, Healthcare, and Technology sectors. The overall credit quality of the portfolio has improved during the reporting period. In the current market environment, the team has found that on a relative value basis, loans issued by companies with less leverage on their balance sheets tend to offer better risk-adjusted return characteristics than those with more debt.

At period end, the overall credit quality of the loan market is also solid with defaults of approximately 2.5%. While select sectors, such as Healthcare and Retail, are experiencing challenges specific to their industries, we believe credit fundamentals can

continue to remain healthy for the remainder of 2018.

The percentages above are based on the market value of the Fund’s securities as of July 31, 2018, and are subject to change. Except for securities labeled “Unrated,” all securities have been rated by at least one Nationally Recognized Statistical Rating Organization (“NRSRO”), such as S&P Global Ratings (“S&P”). For securities rated only by an NRSRO other than S&P, OppenheimerFunds, Inc. (the “Sub-Adviser”) converts that rating to the equivalent S&P rating. If two or more NRSROs have assigned a rating to a security, the highest S&P equivalent rating is used. For securities not rated by an NRSRO, the Sub-Adviser uses its own credit analysis to assign ratings in categories similar to those of S&P. The use of similar categories is not an indication that the Sub-Adviser’s credit analysis process is consistent or comparable with any NRSRO’s process were that NRSRO to rate the same security. Fund assets invested in Oppenheimer Institutional Government Money Market Fund are assigned that fund’s S&P rating, which is currently AAA. For the purposes of this table, “investment-grade” securities are securities rated within the NRSROs’ four highest rating categories (AAA, AA, A and BBB). Unrated securities do not necessarily indicate low credit quality, and may or may not be the equivalent of investment-grade. Please consult the Fund’s prospectus and Statement of Additional Information for further information.

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 3.50% and for Class C shares, the 1% contingent deferred sales charge for the 1-year period. There is no sales charge for Class I and 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 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 Fund’s performance is compared to the performance of the J.P. Morgan Leveraged Loan Index, which tracks the performance of U.S. dollar denominated senior floating rate bank loans. 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 I	1,000.00	1,017.60	7.28
Class Y	1,000.00	1,017.06	7.83

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		1.82	%
Class C		2.62
Class I		1.45
Class Y		1.56

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.

NOTES TO FINANCIAL STATEMENTS July 31, 2018

1. Organization

Oppenheimer Senior Floating Rate Plus 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 income. 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 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 shares are sold without a front-end sales charge but may be subject to a contingent deferred sales charge (“CDSC”). 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 and C 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 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

2. Significant Accounting Policies (Continued)

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 0.50%. The “Reduction to custodian expenses” line item, if applicable, represents earnings on cash balances maintained by the Fund during the period. Such interest expense and other custodian fees may be paid with these earnings.

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

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.

$55,435		$—		$2,743,442		$879,492

1. At period end, the Fund had $2,743,442 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 utilized $126,499 of capital loss carryforward to offset capital gains realized in that fiscal year.

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

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.

Reduction to Accumulated Net Investment Income	Reduction to Accumulated Net Realized Loss on Investments
$330,754		$330,754

Distributions paid from:

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.

Gross unrealized appreciation	$	1,557,971
Gross unrealized depreciation		(2,437,463)
Net unrealized depreciation	$	(879,492)

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:

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

44       OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

3. Securities Valuation (Continued)

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 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.

Loans are valued at the mean between the bid and asked prices utilizing evaluated prices obtained from third party pricing services or broker-dealers. Standard inputs generally considered by third-party pricing vendors include information obtained from market participants regarding broker-dealer price quotations.

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

3. Securities Valuation (Continued)

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 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:

(a) Securities classified as Level 3 whose unadjusted values were provided by a pricing service or broker-dealer for which such inputs are unobservable. The Manager periodically reviews pricing vendor and broker methodologies and inputs to confirm they are determined using unobservable inputs and have been appropriately classified. Such securities’ fair valuations could change significantly based on changes in unobservable inputs used by the pricing service or broker.

(b) The Fund fair values certain corporate loans using a discounted cash flow model which incorporates the Company’s EBITDA and leverage to determine an implied rating. The yield to maturity on other issues with similar leverage and rating is used as a basis for the discount rate, with an additional illiquidity discount applied. The illiquidity discount was determined based on the implied discount rate at origination. The Manager periodically reviews the financial statements and monitors such investments for additional market information or the occurrence of a significant event which would warrant a re-evaluation of the security’s fair valuation. Such security’s fair valuation could increase (decrease) significantly based on a decrease (increase) in the illiquidity discount. Such security’s fair

48       OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

3. Securities Valuation (Continued)

valuation could also increase (decrease) based on an increase (decrease) in the implied rating or a decrease (increase) in the yield to maturity on other issues.

(c) The Fund fair values certain securities held at a nominal value to reflect the low probability of receipt of future payments to be received. The Manager monitors such investments for additional market information or the occurrence of a significant event which would warrant a re-evaluation of the security’s fair valuation.

(d) The Fund fair values certain common stocks received from a restructuring at the estimated amount of future recovery proceeds. This estimate is based on the market value of the original loan held prior to the restructuring (as determined by a pricing service) less the cash distribution received as part of the restructuring. The Manager monitors such investments for additional market information or the occurrence of a significant event which would warrant a re-evaluation of the security’s fair valuation. A significant increase (decrease) in the market value of the original loan position will result in a significant increase (decrease) to the fair value of the investment.

(e) The Fund fair values certain common stocks received following a merger at the estimated amount of future recovery proceeds from the sale of assets as disclosed within the Company’s financial statements, less cash distributions received. The Manager monitors such investments for additional market information or the occurrence of a significant event which would warrant a re-evaluation of the security’s fair valuation. A significant increase (decrease) in the auction proceeds will result in a significant increase (decrease) to the fair value of the investment.

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 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.

Senior Loans. Under normal market conditions, the Fund will invest at least 80% of its net assets (plus borrowings for investment purposes) in floating rate senior loans made to U.S. and foreign borrowers that are corporations, partnerships or other business entities. The Fund

49       OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

NOTES TO FINANCIAL STATEMENTS Continued

4. Investments and Risks (Continued)

will do so either as an original lender or as a purchaser of a loan assignment or a participation interest in a loan. While most of these loans will be collateralized, the Fund can invest without limit in uncollateralized floating rate senior loans. Senior loans are often issued in connection with recapitalizations, acquisitions, leveraged buyouts, and refinancing of borrowers. The senior loans pay interest at rates that float above (or are adjusted periodically based on) a benchmark that reflects current interest rates. Senior loans generally are not listed on any national securities exchange or automated quotation system and no active trading market exists for some senior loans. As a result, some senior loans are illiquid, which may make it difficult for the Fund to value them or dispose of them at an acceptable price when necessary.

To the extent that a secondary market does exist for certain senior loans, the market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods.

When investing in senior loans, the Fund generally will have a contractual relationship only with the lender, not with the relevant borrower. As a result, the Fund generally will have the right to receive payments of principal, interest, and any fees to which it is entitled only from the lender selling the participation and only upon receipt by the lender of the payments from the relevant borrower. The Fund may not directly benefit from the collateral supporting the debt obligation in which it has purchased the participation. As a result, the Fund will assume the credit risk of both the borrower and the institution selling the participation to the Fund.

At period end, securities with an aggregate market value of $82,061,524, representing 110.89% of the Fund’s net assets were comprised of senior loans.

Securities on a When-Issued or Delayed Delivery Basis. The Fund purchases and sells interests in Senior Loans and other portfolio 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.

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

50       OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

4. Investments and Risks (Continued)

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.

Credit Risk. Senior loans are subject to credit risk. Credit risk relates to the ability of the borrower under a senior loan to make interest and principal payments as they become due. The Fund’s investments in senior loans are subject to risk of missing an interest and/or principal payment.

Information concerning securities not accruing income at period end is as follows:

Cost	$2,257,769
Market Value	$1,995,283
Market Value as % of Net Assets	2.70%

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,

5. Market Risk Factors (Continued)

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.

8. 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 $200 million	0.80%
Next $200 million	0.77
Next $200 million	0.74
Next $200 million	0.71
Next $4.2 billion	0.65
Over $5 billion	0.63

The Fund’s effective management fee for the reporting period was 0.80% 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

NOTES TO FINANCIAL STATEMENTS Continued

8. Fees and Other Transactions with Affiliates (Continued)

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 Plan for Class C Shares. The Fund has adopted a Distribution and Service Plan (the “Plan”) for Class C 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 Plan, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class C shares’ daily net assets. The Fund also pays a service fee under the Plan at an annual rate of 0.25% of daily net assets. The Plan continues 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 Plan 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.

Year Ended	Class A Front-End Sales Charges Retained by Distributor		Class A Contingent Deferred Sales Charges Retained by Distributor		Class C  Contingent  Deferred  Sales Charges  Retained by  Distributor

8. Fees and Other Transactions with Affiliates (Continued)

Waivers and Reimbursements of Expenses. The Manager has contractually agreed to waive fees and/or reimburse the Fund for certain expenses so the that “Expenses after payments, waivers and/or reimbursements and reduction to custodian expenses excluding interest and fees from borrowings” will not exceed the following annual rates: 1.30% for Class A shares, 2.10% for Class C shares, 0.95% for Class I shares and 1.05% for Class Y shares.

During the reporting period, the Manager waived fees and/or reimbursed the Fund as follows:

Class A	$48,449
Class C	18,141
Class I	883
Class Y	42,374

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.

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, and Y.

During the reporting period, the Transfer Agent waived fees and/or reimbursed the Fund for transfer agent and shareholder servicing agent fees as follows:

Class A	$1,873
Class C	935

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 IGMMF. During the reporting period, the Manager waived fees and/or reimbursed the Fund $602 for IGMMF 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.

9. Borrowings and Other Financing

Borrowings. The Fund has entered into a Loan and Security Agreement (the “Agreement”) with Deutsche Bank (the “Bank”), that enables it to borrow up to $50 million. To secure loans under the Agreement, the Fund has granted a security interest in its senior loans and other portfolio securities to the Bank. Interest is charged to the Fund, based on its borrowings, at a spread above three-month LIBOR (4.0486% at period end). The Fund pays additional fees annually under the Agreement for management and administration of the facility as well as ongoing commitment fees all of which are based on the total facility size. Total fees and interest that are included in expenses on the Fund’s Statement of Operations related to its participation in the loan facility during the reporting period equal 0.45% of the Fund’s average net assets on an annualized basis. Under the Agreement, the Fund has the right to

55       OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

NOTES TO FINANCIAL STATEMENTS Continued

9. Borrowings and Other Financing (Continued)

prepay loans and terminate its participation in the loan facility at any time upon prior notice to the lenders.

The Fund can borrow money from the Bank in amounts up to one third of its total assets (including the amount borrowed) less all liabilities and indebtedness other than borrowings (meaning that the value of those assets must be at least 300% of the amount borrowed). The Fund can use those borrowings for investment-related purposes such as purchasing senior loans and other portfolio securities. The Fund also may borrow to meet redemption obligations or for temporary and emergency purposes. When the Fund invests borrowed money in senior loans or other portfolio securities, it is using a speculative investment technique known as leverage and changes in the value of the Fund’s investments will have a larger effect on its share price than if it did not borrow because of the effect of leverage.

The Fund will pay interest and may pay other fees in connection with loans. If the Fund does borrow, it will be subject to greater expenses than funds that do not borrow. The interest on borrowed money and the other fees incurred in conjunction with loans are an expense that might reduce the Fund’s yield and return. Expenses incurred by the Fund with respect to interest on borrowings and related fees are disclosed separately or as other expenses on the Statement of Operations.

At period end, the Fund had borrowings outstanding at an interest rate of 4.0486%.

Details of the borrowings for the reporting period are as follows:

Average Daily Loan Balance	$	7,332,877
Average Daily Interest Rate		3.5474	%
Fees Paid	$	75,000
Interest Paid	$	239,253

Loan Commitments. Pursuant to the terms of certain credit agreements, the Fund has unfunded loan commitments of $42,000 at period end. The Fund generally will maintain with its custodian, liquid investments having an aggregate value at least equal to the par value of unfunded loan commitments. At period end, these investments have a market value of $41,837 and have been included as Corporate Loans in the Statement of Investments.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees

Oppenheimer Senior Floating Rate Plus Fund:

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Oppenheimer Senior Floating Rate Plus Fund (the “Fund”), including the statement of investments, as of July 31, 2018, the related statements of operations and cash flows 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 four year period then ended, and for the period from August 23, 2013 (commencement of operations) to July 31, 2014. 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 and its cash flows 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 four year period then ended, and for the period from August 23, 2013 (commencement of operations) to July 31, 2014, 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.

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.

Dividends, if any, paid by the Fund during the reporting period which are not designated as capital gain distributions should be multiplied by the maximum amount allowable but not less than 2.47% to arrive at the amount eligible for the corporate dividend-received deduction.

A portion, if any, of the dividends paid by the Fund during the reporting period which are not designated as capital gain distributions are eligible for lower individual income tax rates to the extent that the Fund has received qualified dividend income as stipulated by recent tax legislation. The maximum amount allowable but not less than $78,090 of the Fund’s fiscal year taxable income may be eligible for the lower individual income tax rates. In early 2018, shareholders of record received information regarding the percentage of distributions that are eligible for lower individual income tax rates.

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 $2,854,219 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.

Internet Security and Encryption

In general, the email services provided by our website are encrypted and provide a secure and private means of communication with us. To protect your own privacy, confidential and/ or personal information should only be communicated via email when you are advised that you are using a secure website.

As a security measure, we do not include personal or account information in non-secure emails, and we advise you not to send such information to us in non-secure emails. Instead, you may take advantage of the secure features of our website to encrypt your email correspondence. To do this, you will need to use a browser that supports Secure Sockets Layer (SSL) protocol.

● 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.

● You can exit the secure area by closing your browser or, for added security, you can use the Log Out button before you close your browser.

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.
