Fund Performance Discussion

The Fund’s Class A shares (without sales charge) produced a total return of -2.04% during the six-month reporting period, lagging its benchmark, the J.P. Morgan Leveraged Loan Index, which returned 0.06%. Senior loans generally fell out of favor at a time when risk-averse global investors engaged in a “flight to quality” toward fixed-rate U.S. Treasury securities. The Fund’s results compared to the benchmark were constrained by shortfalls in the energy sector, and its use of leverage further magnified underperformance.

MARKET OVERVIEW

The U.S. economic recovery continued to gain momentum over the reporting period, as evidenced by a 5.0% annualized Gross Domestic Product (“GDP”) growth rate for the third quarter of 2014 and an estimated 2.2% growth rate for the fourth quarter. The domestic economy responded positively to a falling unemployment rate, the creation of hundreds of thousands of new jobs each month, intensifying domestic manufacturing activity, and improved consumer and business confidence. These encouraging developments made the Federal Reserve (the “Fed”) comfortable in ending its massive quantitative easing program by the end of October 2014. However, as it has since December 2007, the Fed left its target for short-term interest rates unchanged in a historically low range between 0% and 0.25%.

In contrast to the improving U.S. economy, most overseas markets continued to struggle with economic weakness and deflationary pressures. Most notably, crude oil prices plummeted over the reporting period due to a glut of supply amid tepid global demand. In response, central banks in Europe and Japan

implemented aggressively accommodative monetary policy measures that drove yields of higher quality sovereign bonds to very low levels. Global investors engaged in a “flight to quality” in which they sought more competitive levels of current income from sovereign bonds in other markets. These risk-averse investors increasingly turned to U.S. Treasury obligations, where surging demand for a limited supply of securities drove yields lower over the reporting period. Falling long-term interest rates defied the expectations of many analysts, as yields of U.S. government securities typically climb during economic recoveries.

In this environment, unfavorable supply-and-demand dynamics stemming from the global flight to quality caused senior loans to underperform their fixed-rate counterparts. Yet, it is important to note that underlying credit fundamentals in the loan market generally remained sound, as evidenced by a default rate of less than 2%. The energy sector represented one notable exception: the sharp decline in energy commodity prices undermined the earnings of some companies

engaged in the production of oil and natural gas.

FUND REVIEW

The Fund’s performance compared to its benchmark was dampened by overweight exposure to the struggling energy sector. We reduced the Fund’s positions in the energy sector toward a more market-neutral weighting as oil prices fell, but it was not sufficient to completely avoid the adverse impact of the sector’s relative weakness. The Fund’s use of leverage magnified the impact of this shortfall.

The Fund achieved more positive results in other areas of the senior loan market. The Fund’s investments in the transportation sector fared particularly well, in part due to investors’ positive response to the refinancing of a formerly distressed loan to a company whose business fundamentals have improved. Our decision to reduce the Fund’s exposure to the coal production industry helped bolster relative results in the metals-and-mining industry group. Favorable individual credit selections also buoyed relative performance in the health care sector.

STRATEGY & OUTLOOK

As of the reporting period’s end, we have remained optimistic regarding the impact of a sustained U.S. economic recovery on credit fundamentals in the senior loan market. In

our judgment, global deflation concerns are likely to moderate as energy prices stabilize, and aggressively accommodative monetary policies in Europe and Japan could support better economic conditions in overseas markets. These potential developments could revive investors’ interest in riskier asset classes that provide highly competitive levels of current income.

In the meantime, we have seen no signs of abatement in the U.S. economic recovery. In fact, many analysts believe that the Fed is poised to begin raising short-term interest rates later in 2015 if, as expected, labor market conditions continue to improve and inflationary pressures begin to increase. Historically, rising short-term interest rates have been good for assets with floating rates, including senior loans.

In anticipation of improved investor sentiment in the bank loan market, we have maintained the Fund’s focus on loans with credit ratings in the “single B” category, which we believe offer particularly attractive yields and valuations. The Fund ended the reporting period without major emphases or de-emphases on individual market sectors or industry groups, but we intend to continue to monitor the energy sector carefully, and we are prepared to reduce exposure further if warranted by macroeconomic and industry developments.

The percentages above are based on the market value of the Fund’s securities as of January 30, 2015, and are subject to change. Except for securities labeled “Unrated” and except for certain securities issued or guaranteed by a foreign sovereign, all securities have been rated by at least one Nationally Recognized Statistical Rating Organization (“NRSRO”), such as Standard & Poor’s (“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. Unrated securities issued or guaranteed by a foreign sovereign are assigned a credit rating equal to the highest NRSRO rating assigned to that foreign sovereign. 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 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 CDSC of 1% for the 1-year period. There is no sales charge for Class I and Class Y shares. Returns for periods of less than one year are cumulative and not annualized.

Standardized yield is based on net investment income for the 30-day period ended 1/31/15 and the maximum offering price at the end of the period (including the maximum sales charge) for Class A shares and the net asset value for Class C, Class I, and Class Y shares. Each result is compounded semiannually and then annualized. Falling share prices will tend to artificially raise yields.

The Fund’s performance is compared to the performance of the J.P. Morgan Leveraged Loan Index and the Credit Suisse Leveraged Loan Index. The J.P. Morgan Leveraged Loan Index tracks the performance of U.S. dollar denominated senior floating rate bank loans. The Credit

Fund Expenses

Fund Expenses. As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, which may include sales charges (loads) on purchase payments, contingent deferred sales charges on redemptions; and (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 for Actual Expenses are based on an investment of $1,000.00 invested at the beginning of the period, August 23, 2013 (commencement of operations) and held for the period ended January 30, 2015.

The Hypothetical Examples for Comparison Purposes are based on an investment of $1,000.00 invested on May 1, 2013 and held for the six months ended January 30, 2015.

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 Period” 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 actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example for the class of shares you hold with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as front-end or contingent deferred sales charges (loads), or a $12.00 fee imposed annually on accounts valued at less than $500.00 (subject to exceptions described in the Statement of Additional Information). 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		1,016.24		8.93
Class Y		1,000.00		1,015.59		9.59

Expenses are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period). Those annualized expense ratios, excluding indirect expenses from affiliated funds, based on the 6-month period ended January 30, 2015 are as follows:

Class	Expense Ratios
Class A		2.12	%
Class C		2.93
Class I		1.76
Class Y		1.89

The expense ratios reflect voluntary and/or contractual waivers and/or reimbursements of expenses by the Fund’s Manager. 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 January 30, 2015 Unaudited

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 commenced operations on August 23, 2013. As of January 30, 2015, approximately 30% of the shares of the Fund were owned by the Manager, other funds advised or sub-advised by the Manager or an affiliate of the Manager.

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 consistently followed by the Fund.

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

Semiannual and Annual Periods. The last day of the Fund’s semiannual and annual periods was the last day the New York Stock Exchange was open for trading. The Fund’s financial statements have been presented through that date to maintain consistency with the Fund’s net asset value calculations used for shareholder transactions.

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.

2. Significant Accounting Policies (Continued)

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. generally accepted accounting principles, 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.

The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made to shareholders prior to the Fund’s fiscal year end may ultimately be categorized as a tax return of capital.

Investment Income. Dividend income is recorded on the ex-dividend date or upon ex-dividend notification in the case of certain foreign dividends where the ex-dividend date may have passed. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Interest income 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 at a rate equal to the Federal Funds Rate.

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 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 remain open for the three preceding fiscal reporting period ends.

2. Significant Accounting Policies (Continued)

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

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 as of January 30, 2015 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	$	61,488,499
Gross unrealized appreciation	$	101,076
Gross unrealized depreciation		(1,874,533	)
Net unrealized depreciation	$	(1,773,457	)

Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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.

3. Securities Valuation

The Fund calculates the net asset value of its shares as of the close of the New York Stock Exchange (the “Exchange”), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading.

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 its next regularly scheduled meeting covering the calendar quarter in which the fair valuation was determined.

Valuation Methods and Inputs

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

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

38      OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

3. Securities Valuation (Continued)

Securities traded on a registered U.S. securities exchange (including exchange-traded derivatives other than futures and futures options) are valued based on the last sale price of the security reported on the principal exchange on which it is traded, prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the current day’s closing “bid” and “asked” prices, and if not, at the current day’s closing bid price. A security of a foreign issuer traded on a foreign exchange, but not listed on a registered U.S. securities exchange, is valued based on the last sale price on the principal exchange on which the security is traded, as identified by the third party pricing service used by the Manager, prior to the time when the Fund’s assets are valued. If the last sale price is unavailable, the security is valued at the most recent official closing price on the principal exchange on which it is traded. If the last sales price or official closing price for a foreign security is not available, the security is valued at the mean between the bid and asked price per the exchange or, if not available from the exchange, obtained from two dealers. If bid and asked prices are not available from either the exchange or two dealers, the security is valued by using one of the following methodologies (listed in order of priority): (1) using a bid from the exchange, (2) the mean between the bid and asked price as provided by a single dealer, or (3) a bid from a single dealer.

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, event-linked bonds, loans, 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.

Short-term money market type debt securities with a remaining maturity of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity (amortized cost), which approximates market value. Short-term debt securities with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing evaluated prices obtained from third party pricing services or broker-dealers.

A description of the standard inputs that may generally be considered by the third party pricing vendors in determining their evaluated prices is provided below.

Security Type	Standard inputs generally considered by third-party pricing vendors
Corporate debt, government debt, municipal, mortgage-backed and asset-backed securities	Reported trade data, broker-dealer price quotations, benchmark yields, issuer spreads on comparable securities, the credit quality, yield, maturity, and other appropriate factors.
Loans	Information obtained from market participants regarding reported trade data and broker-dealer price quotations.
Event-linked bonds	Information obtained from market participants regarding reported trade data and broker-dealer price quotations.

3. Securities Valuation (Continued)

If a market value or price cannot be determined for a security using the methodologies described above, or if, in the “good faith” opinion of the Manager, the market value or price obtained does not constitute a “readily available market quotation,” or a significant event has occurred that would materially affect the value of the security, the security is 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. Fair value determinations by the Manager are subject to review, approval and ratification by the Fund’s Board at its next regularly scheduled meeting covering the calendar quarter in which the fair valuation was determined. Those fair valuation standardized 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, or its third party service provider who is subject to oversight by the Manager, regularly compares prior day prices, prices on comparable securities, and sale prices to the current day prices and challenges those prices exceeding certain tolerance levels with the third party pricing service or broker source. For those securities valued by fair valuations, whether through a standardized fair valuation methodology or a fair valuation determination, the Valuation Committee reviews and affirms the reasonableness of the valuations based on such methodologies and fair valuation determinations on a regular basis after considering all relevant information that is reasonably available.

Classifications

Each investment asset or liability of the Fund is assigned a level at measurement date based on the significance and source of the inputs to its valuation. Various data inputs are 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.)

40      OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

3. Securities Valuation (Continued)

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 table below categorizes amounts that are included in the Fund’s Statement of Assets and Liabilities as of January 30, 2015 based on valuation input level:

					Level 3—
	Level 1—		Level 2—		Significant
	Unadjusted		Other Significant		Unobservable
	Quoted Prices		Observable Inputs		Inputs		Value

Total Assets	$	—	$	59,715,042	$	—	$	59,715,042

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

4. Investments and Risks

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 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 also under normal market conditions invest up to 10% of its net assets (plus borrowings for investment purposes) 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.

As of January 30, 2015, securities with an aggregate market value of $59,613,192, representing 134.02% 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

41      OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

NOTES TO FINANCIAL STATEMENTS Unaudited / Continued

4. Investments and Risks (Continued)

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.

Restricted Securities. As of January 30, 2015, investments in securities included issues that are restricted. A restricted security may have a contractual restriction on its resale and is valued under methods approved by the Board of Trustees as reflecting fair value. Securities that are restricted are marked with an applicable footnote on the Statement of Investments. Restricted securities are reported on a schedule following the Statement of Investments.

5. Shares of Beneficial Interest

The Fund has authorized an unlimited number of $0.001 par value shares of beneficial interest of each class. Transactions in shares of beneficial interest were as follows:

6. Purchases and Sales of Securities

The aggregate cost of purchases and proceeds from sales of securities, other than short-term obligations and investments in IMMF, for the six months ended January 30, 2015 were as follows:

	Purchases		Sales
Investment securities		$15,882,534		$24,132,402

7. 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 management fee for the fiscal six months ended January 30, 2015 was 0.81% of average annual net assets before any applicable waivers.

43      OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

NOTES TO FINANCIAL STATEMENTS Unaudited / Continued

7. Fees and Other Transactions with Affiliates (Continued)

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. 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 Trustee under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of the Fund or in other Oppenheimer funds selected by the Trustee. The Fund purchases shares of the funds selected for deferral by the Trustee in amounts equal to his or her deemed investment, resulting in a Fund asset equal to the deferred compensation liability. Such assets are included as a component of “Other” within the asset section of the Statement of Assets and Liabilities. Deferral of Trustees’ fees under the plan will not affect the net assets of the Fund and will not materially affect the Fund’s assets, liabilities or net investment income per share. Amounts will be deferred until distributed in accordance with the compensation deferral plan.

Offering and Organizational Costs. The Manager paid all initial offering and organizational costs associated with the registration and seeding of the Fund.

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

44       OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

7. Fees and Other Transactions with Affiliates (Continued)

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 vote annually to approve its 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.

Six Months 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
January 30, 2015	$	12,673	$	1,662	$	855

Waivers and Reimbursements of Expenses. The Manager has voluntarily 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 1.30% of average annual net assets for Class A shares, 2.10% of average annual net assets for Class C shares, 0.95% of average annual net assets for Class I shares and 1.05% of average annual nets assets for Class Y shares. During the six months ended January 30, 2015, the Manager reimbursed $51,684, $13,494, $14 and $6,941 for Class A, Class C, Class I and Class Y shares, respectively.

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 IMMF. During the six months ended January 30, 2015, the Manager waived fees and/or reimbursed the Fund $508 for IMMF management fees.

7. Fees and Other Transactions with Affiliates (Continued)

These undertakings may be modified or terminated as set forth according to the terms in the prospectus.

8. 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 (1.9531% as of January 30, 2015). 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 six months ended January 30, 2015 equal 0.82% of the Fund’s average net assets on an annualized basis. Under the Agreement, the Fund has the right to 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.

As of January 30, 2015, the Fund had borrowings outstanding at an interest rate of 1.9531%. Details of the borrowings for the six months ended January 30, 2015 are as follows:

Average Daily Loan Balance	$	17,842,663
Average Daily Interest Rate		1.939	%
Fees Paid	$	—
Interest Paid	$	164,784

46       OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

8. Borrowings and Other Financing (Continued)

Loan Commitments. Pursuant to the terms of certain credit agreements, the Fund has unfunded loan commitments of $44,460 at January 30, 2015. 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 January 30, 2015, these commitments have a market value of $44,460 and have been included as Corporate Loans in the Statement of Investments. The following commitments are subject to funding based on the borrower’s discretion. The Fund is obligated to fund these commitments at the time of the request by the borrower. These commitments have been excluded from the Statement of Investments. The unrealized appreciation/depreciation on these commitments is recorded as an asset/liability on the Statement of Assets and Liabilities.

9. Pending Litigation

In 2009, seven class action lawsuits were filed in the U.S. District Court for the District of Colorado against OppenheimerFunds, Inc. (“OFI”), OppenheimerFunds Distributor, Inc., the Fund’s principal underwriter and distributor (the “Distributor”), and certain funds (but not including the Fund) advised by OFI Global Asset Management, Inc. and distributed by the Distributor (the “Defendant Funds”). The lawsuits also named as defendants certain officers and current and former trustees of the respective Defendant Funds. The lawsuits raised claims under federal securities laws and alleged, among other things, that the disclosure documents of the respective Defendant Funds contained misrepresentations and omissions and that the respective Defendant Funds’ investment policies were not followed. The plaintiffs in these actions sought unspecified damages, equitable relief and awards of attorneys’ fees and litigation expenses. The Defendant Funds’ Boards of Trustees also engaged counsel to represent the Funds and the present and former Independent Trustees named in those suits. In March 2014, the parties in six of these lawsuits executed stipulations and agreements of settlement resolving those actions. In July 2014, the court entered an order and final judgment approving the settlements as fair, reasonable and adequate. The settlements do not resolve a seventh outstanding lawsuit relating to Oppenheimer Rochester California Municipal Fund (the “California Fund Suit”). OFI believes the California Fund Suit is without legal merit and is defending the suit vigorously. While it is premature to render any opinion as to the outcome in the California Fund Suit, or whether any costs that OFI may bear in defending the California Fund Suit might not be reimbursed by insurance, OFI believes the California Fund Suit should not impair the ability of OFI or the Distributor to perform their respective duties to the Fund, and that the outcome of the California Fund Suit should not have any material effect on the operations of any of the Oppenheimer funds.

47       OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

BOARD APPROVAL OF THE FUND’S INVESTMENT ADVISORY AND

SUB-ADVISORY AGREEMENTS Unaudited

The Fund has entered into an investment advisory agreement with OFI Global Asset Management, Inc. (“OFI Global” or the “Adviser”), a wholly-owned subsidiary of OppenheimerFunds, Inc. (“OFI” or the “Sub-Adviser”) (“OFI Global” and “OFI” together the “Managers”) and OFI Global has entered into a sub-advisory agreement with OFI whereby OFI provides investment sub-advisory services to the Fund (collectively, the “Agreements”). Each year, the Board of Trustees (the “Board”), including a majority of the independent Trustees, is required to determine whether to renew the Agreements. The Investment Company Act of 1940, as amended, requires that the Board request and evaluate, and that the Managers provide, such information as may be reasonably necessary to evaluate the terms of the Agreements. The Board employs an independent consultant to prepare a report that provides information, including comparative information that the Board requests for that purpose. In addition to in-person meetings focused on this evaluation, the Board receives information throughout the year regarding Fund services, fees, expenses and performance.

The Adviser, Sub-Adviser and the independent consultant provided information to the Board on the following factors: (i) the nature, quality and extent of the Managers’ services, (ii) the investment performance of the Fund and the Managers, (iii) the fees and expenses of the Fund, including comparative expense information, (iv) the profitability of the Managers and their affiliates, including an analysis of the cost of providing services, (v) whether economies of scale are realized as the Fund grows and whether fee levels reflect these economies of scale for Fund investors and (vi) other benefits to the Managers from their relationship with the Fund. The Board was aware that there are alternatives to retaining the Managers.

Outlined below is a summary of the principal information considered by the Board as well as the Board’s conclusions.

Nature, Quality and Extent of Services. The Board considered information about the nature, quality and extent of the services provided to the Fund and information regarding the Managers’ key personnel who provide such services. The Sub-Adviser’s duties include providing the Fund with the services of the portfolio managers and the Sub-Adviser’s investment team, who provide research, analysis and other advisory services in regard to the Fund’s investments; securities trading services; oversight of third-party service providers; monitoring compliance with applicable Fund policies and procedures and adherence to the Fund’s investment restrictions; and risk management. The Managers are responsible for providing certain administrative services to the Fund as well. Those services include providing and supervising all administrative and clerical personnel who are necessary in order to provide effective corporate administration for the Fund; compiling and maintaining records with respect to the Fund’s operations; preparing and filing reports required by the Securities and Exchange Commission; preparing periodic reports regarding the operations of the Fund for its shareholders; preparing proxy materials for shareholder meetings; and preparing the registration statements required by Federal and state securities laws for the sale of the Fund’s shares. The Managers also provide the Fund with office space, facilities and equipment.

The Board also considered the quality of the services provided and the quality of the Managers’ resources that are available to the Fund. The Board took account of the fact that the Sub-Adviser has had over fifty years of experience as an investment adviser and that its assets under management rank it among the top mutual fund managers in the United States. The Board evaluated the Sub-Adviser’s advisory, administrative, accounting, legal, compliance

services and risk management, and information the Board has received regarding the experience and professional qualifications of the Managers’ key personnel and the size and functions of its staff. In its evaluation of the quality of the portfolio management services provided, the Board considered the experience of Joseph Welsh and Margaret Hui, the portfolio managers for the Fund, and the Sub-Adviser’s investment team and analysts. The Board members also considered the totality of their experiences with the Managers as directors or trustees of the Fund and other funds advised by the Managers. The Board considered information regarding the quality of services provided by affiliates of the Managers, which its members have become knowledgeable about in connection with the renewal of the Fund’s service agreements. The Board concluded, in light of the Managers’ experience, reputation, personnel, operations and resources that the Fund benefits from the services provided under the Agreements.

Investment Performance of the Manager, the Sub-Adviser and the Fund. The Board considered that the Fund was launched on August 23, 2013 and therefore does not have a full calendar year of performance. The Board noted that the Fund’s 2014 performance is strong, ranking in the 12th percentile of its category for the year-to-date period ended April 30, 2014.

Costs of Services by the Manager. The Board reviewed the fees paid to the Manager and the Sub-Adviser and the other expenses borne by the Fund. The Board noted that the Manager, not the Fund, pays the Sub-Adviser’s fee under the sub-advisory agreement. The independent consultant provided comparative data in regard to the fees and expenses of the Fund and other retail bank loan funds with comparable asset levels and distribution features. The Board also noted that the Fund’s contractual management fees and total expenses were higher than their respective peer group medians and category medians. Within the total asset range of $0 to $50 million, the Fund’s effective management fee rate was higher than its peer group median and category median. The Board considered that the Fund’s contractual management fees ranked in the fourth quintile of its expense group and that its total expenses ranked in the fifth quintiles of its expense group. The Board also considered that the Fund employs leverage in its investment strategy, which according to the Manager, justifies slightly higher fees and expenses than many of the funds in the peer group. The Board also considered that the Manager has contractually agreed to waive fees and/or reimburse certain expenses so that the total annual fund operating expenses as a percentage of average daily net assets will not exceed the following annual rates: 1.30% for Class A Shares, 2.10% for Class C Shares, 1.05% for Class Y Shares, and 0.95% for Class I Shares.

Economies of Scale and Profits Realized by the Manager and Sub-Adviser. The Board considered information regarding the Managers’ costs in serving as the Fund’s investment adviser and sub-adviser, including the costs associated with the personnel and systems necessary to manage the Fund. The Board reviewed whether the Managers realize economies of scale in managing and supporting the Fund. The Board noted that the Fund currently has management fee breakpoints, which are intended to share with Fund shareholders economies of scale that may exist as the Fund’s assets grow.

Other Benefits to the Managers. In addition to considering the profits realized by the Managers, the Board considered information that was provided regarding the direct and indirect benefits the Managers receive as a result of their relationship with the Fund, including

49       OPPENHEIMER SENIOR FLOATING RATE PLUS FUND

BOARD APPROVAL OF THE FUND’S INVESTMENT ADVISORY AND

SUB-ADVISORY AGREEMENTS Unaudited / Continued

compensation paid to the Managers’ affiliates. The Board also considered that the Managers must be able to pay and retain experienced professional personnel at competitive rates to provide quality services to the Fund.

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

Based on its review of the information it received and its evaluations described above, the Board, including a majority of the independent Trustees, decided to continue the Agreements through August 31, 2015. In arriving at its decision, the Board did not identify any factor or factors as being more important than others, but considered all of the above information, and considered the terms and conditions of the Agreements, including the management fees, in light of all the surrounding circumstances.

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.

Disclosure of Information

Copies of confirmations, account statements and other documents reporting activity in your fund accounts are made available to your financial advisor (as designated by you). We may also use details about you and your investments to help us, our financial service affiliates, or firms that jointly market their financial products and services with ours, to better serve your investment needs or suggest financial services or educational material that may be of interest to you.

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.

We do not guarantee or warrant that any part of our website, including files available for download, are free of viruses or other harmful code. It is your responsibility to take appropriate precautions, such as use of an anti-virus software package, to protect your computer hardware and software.

— All transactions, including redemptions, exchanges and purchases, are secured by SSL and 128-bit encryption. 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 either 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, do not allow it to be used by anyone else. Also, take special precautions when accessing your account on a computer used by others.
