Fund Performance Discussion

The Fund’s Class A shares (without sales charge) produced a total return of 6.31% during the reporting period. In comparison, master limited partnerships (“MLPs”), as measured by the Alerian MLP Index (AMZ), provided a total return gain of 9.28%. Please note that the returns for the Alerian MLP Index are calculated pre-tax, while the Fund’s returns are calculated post corporate tax. During the same period, the S&P 500 Index produced a total return gain of 8.06%.

Over the twelve-month reporting period ended November 30, 2016, the midstream sector outperformed the broader markets as the lows of the current energy cycle appear to have been reached and the beginnings of a recovery appear to be unfolding. Late in the period, the Organization of Petroleum Exporting Countries (“OPEC”) provided a potential acceleration to the rebalancing of crude oil supply and demand by announcing formal plans to reduce its production to 32.5 million barrels of oil per day (MMbbls/d) by January 2017. Agreements with non-OPEC countries to provide additional support via another 0.6 MMbbls/d of supply reductions were also announced, most notably with Russia electing to reduce production by 0.3 MMbbls/d. The larger than expected supply reduction sent oil prices sharply higher and many energy equities even more so. This reduced supply from OPEC members will pull the consensus estimates for the 2017 oil market balance back firmly into an undersupplied position, thereby beginning the process of working down

OPPENHEIMER STEELPATH MLP SELECT 40 FUND 3

global inventories. And, importantly for U.S. midstream investors, the OPEC cut helps reduce the market forces that were driving near-term U.S. production, and thus midstream throughput, lower. Further, we continue to believe that this energy down cycle has shifted the call on U.S.-sourced volumes higher over the medium-term. This improving fundamental commodity picture, combined with midstream valuations that remain below long-term averages, makes a compelling case for midstream investment.

Over the reporting period, we estimate approximately $26 billion of new equity supply entered the market through either secondary offerings, initial public offerings, or “at-the-market” programs in which primary units trade into the market anonymously throughout the normal trading day. This pace of equity issuance represents an increase from approximately $20 billion that was raised over the twelve month reporting period ended November 30, 2015. MLPs also raised approximately $23 billion of debt capital during the period. Most MLPs pay out the majority of excess cash flow as distributions to investors, and therefore must raise external capital to fund growth projects and to fund acquisitions.

MACRO REVIEW

West Texas Intermediate (WTI) crude oil prices ended the reporting period at $49.44 per barrel, up 19% from the prior year. Global crude prices, as measured by Brent crude oil, traded 13% higher over the reporting period. The crude oil price improvement appears linked to the continued moderation in U.S. crude production, healthy demand growth, and the aforementioned OPEC deal to reduce supply. Brent exited the period at a $1 per barrel premium to WTI, which is near the historic norm. However, this reversion represents a departure from the $8 to $9 per barrel Brent premium that has generally existed since 2009.

Henry Hub natural gas spot prices exited the period at $3.30 per million British thermal units (“mmbtu”), up 58% over the reporting period. Natural gas pricing has benefited from a long awaited realignment of supply-demand in which natural gas usage as a heating and electric generation fuel has increased as gas production volume growth has declined, and as increased exports have become a reality via both liquefied natural gas and new pipelines to Mexico.

Mont Belvieu NGL prices ended the reporting period at $23.92 per barrel, a 26% increase over the reporting period. All of the NGL purity products ended the period higher than the same time in the prior year. Frac spreads, a measure of natural gas processing economics, ended the period at $0.28 per gallon, up 4% over the reporting period. Generally, the greater the frac spread, the greater the incentive for producers to seek natural gas processing capacity.

The yield curve modestly flattened over the reporting period as short rates rose more than the yields on longer-dated maturities. The ten-year Treasury yield rose 18 basis points to end the period at 2.38%. The MLP yield spread at period-end, as measured by the AMZ and the 10-year Treasury bond, narrowed by 115 basis points to 5.05%.

4 OPPENHEIMER STEELPATH MLP SELECT 40 FUND

Over the reporting period, real estate investment trusts (“REITs”) and utilities, two competing yield-oriented equity asset classes, posted total returns of 5.65% (as measured by the Dow Jones Equity REIT Total Return Index) and 16.31% (as measured by the Dow Jones Utility Average Index), respectively, as compared to the AMZ’s 9.28% total return. Price to forward distributable cash flow (DCF), a commonly watched ratio within the MLP sector, increased over the period but remains below the ten-year average.

SUBSECTOR REVIEW

Performance among subsectors in the midstream, or energy infrastructure, MLP asset class varied for the reporting period. On average, the gathering and processing subsector provided the best performance over the period, buoyed by improving commodity prices supporting improved volumetric projections. The natural gas pipeline group followed as investors continued to express preference for long-haul natural gas pipelines, particularly those backed by utility demand pull.

The marine subsector experienced the weakest performance over the reporting period as several entities substantially reduced cash distributions to investors. The propane subsector also lagged over the reporting period as market participants appeared to rotate out of the subsector in favor of more traditional midstream names and as rising propane prices could result in some margin pressure in future periods.

FUND REVIEW

Key contributors to the Fund were Williams Partners LP (WPZ) and DCP Midstream Partners, LP (DPM).

WPZ units outperformed over the period after the proposed merger with Energy Transfer was terminated in late June and the Williams enterprise subsequently focused on strengthening its balance sheet, improving liquidity, and preserving its investment grade credit rating. During the period The Williams Companies (WMB) began execution of plans to reinvest $1.7 billion into WPZ, its daughter partnership, via a private purchase of common units and a concurrently announced distribution reinvestment program (“DRIP”). The Williams family also announced a restructuring of gathering agreements with elevated counterparty risk and the sale of Canadian assets that raised $1 billion in cash proceeds.

DPM units benefited from an improving commodity price environment and good operating results. At the partnership’s parent level, management has also been effective at reducing costs, streamlining operations, and reducing commodity price exposure, which have improved market participant sentiment toward DPM units.

OPPENHEIMER STEELPATH MLP SELECT 40 FUND 5

Key detractors from the Fund were Sunoco LP (SUN) and Teekay LNG Partners (TGP).

SUN units underperformed over the period as investor concern increased over the partnership’s elevated leverage metrics following a series of significant acquisitions. We believe the partnership’s diverse geographic footprint and focus on the resilient fuel distribution business should provide the potential for steady long-term operational performance.

TGP units experienced declines early in the reporting period after announcing an unexpected distribution reduction. TGP’s decision to change its dividend payout philosophy was unexpected as the company’s operating performance has continued to be very resilient. TGP’s heavily contracted fleet of LNG carriers generate cash flows that are largely insulated from near-term movements in commodity prices.

Please note that significant decreases in cash distributions from the Fund’s MLP investments and/or significant declines in the fair value of its investments may impact the Fund’s assessment regarding the recoverability of certain deferred tax assets, which may result in the recording of a valuation allowance. If a valuation allowance is established, this could have a material impact on the Fund’s net asset value and results of operations for the period. The Fund had a valuation allowance in place for a portion of the reporting period, but did not have one in place at period end. See Note 2 of the Notes to Financial Statements for more information.

OUTLOOK

We believe we have seen the worst of this energy market down cycle. The rate of midstream growth will likely moderate from peak levels, but average distributions are still likely to grow. Midstream operators may also stand to benefit as they make more efficient use of their existing assets. We believe current market valuations underestimate the potential for renewed business growth going forward and remain optimistic on the sector’s prospects. For this reason, we believe MLPs continue to offer attractive total return potential based on the potential for price appreciation and stable or growing distribution streams.

The Fund’s performance is compared to the performance of the S&P 500 Index and the Alerian MLP Index. The S&P 500 Index is a broad-based measure of domestic stock performance. The Alerian MLP Index is a composite of the 50 most prominent Master Limited Partnerships that provides investors with an unbiased, comprehensive benchmark for this emerging asset class. The Alerian MLP Index, which is calculated using a float-adjusted, capitalization-weighted methodology, is disseminated real-time on a total-return basis. The indices are 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 indices.

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 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 November 30, 2016.

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 November 30, 2016” 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). 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 W	1,000.00	999.15	25.84
CLASS Y	1,000.00	999.13	25.86

Expenses are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 183/366 (to reflect the one-half year period). Those annualized expense ratios, excluding indirect expenses from affiliated funds, based on the 6-month period ended November 30, 2016 are as follows:    

Class	Expense Ratios
CLASS A	5.42%
CLASS C	6.17
CLASS I	5.10
CLASS W	5.17
CLASS Y	5.17

The expense ratios for Class A, C, W, and Y reflect 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, if applicable.

OPPENHEIMER STEELPATH MLP SELECT 40 FUND 23

NOTES TO FINANCIAL STATEMENTS

1. Organization

Oppenheimer SteelPath MLP Select 40 Fund (the “Fund”), a separate series of Oppenheimer SteelPath MLP Funds Trust, is a diversified open-end management investment company registered under the Investment Company Act of 1940, as amended. The Fund’s investment objective is to seek total return. The Fund’s investment adviser is OFI SteelPath, Inc. (the “Adviser” or “Manager”), a wholly-owned subsidiary of OppenheimerFunds, Inc. (“OFI” or “Oppenheimer”).

The Fund offers Class A, Class C, Class I, Class W and Class Y shares. Effective June 28, 2013, Class I shares were renamed Class Y shares and Class Y shares were renamed Class W shares. Effective after August 30, 2013, Class W shares are no longer offered for purchase. Class A shares are sold at their offering price, which is normally net asset value plus a front-end sales charge. Effective June 28, 2013, although there is no initial sales charge on Class A purchases totaling $1 million or more, those Class A shares may be subject to a 1.00% contingent deferred sales charge (“CDSC”) if shares are redeemed within an 18-month “holding period” measured from the date of purchase. Class C shares are sold without a front-end sales charge but may be subject to a CDSC of 1.00% of the redemption proceeds if Class C shares are redeemed within one year of purchase. Class I shares are only available to eligible institutional investors. Class I shares are sold at net asset value per share without a sales charge or CDSC. An institutional investor that buys Class I shares for its customers’ accounts may impose charges on those accounts. Class Y shares are sold at net asset value per share without a sales charge directly to institutional investors that have special agreements with OppenheimerFunds Distributor, Inc. (the “Distributor”) for that purpose. They may include insurance companies, registered investment companies, employee benefit plans and section 529 plans, among others. An institutional investor that buys Class Y shares for its customers’ accounts may impose charges on those accounts. All classes of shares have identical rights and voting privileges with respect to the Fund in general and exclusive voting rights on matters that affect that class alone. Earnings, net assets and net asset value per share may differ due to each class having its own expenses, such as transfer and shareholder servicing agent fees and shareholder communications, directly attributable to that class. Class A and C shares have separate distribution and/or service plans under which they pay fees. Class I, W, and Y shares do not pay such fees.

The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification Topic 946 Financial Services- Investment Companies.

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”).

NOTES TO FINANCIAL STATEMENTS (Continued)

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. generally accepted accounting principles, are recorded on the ex-dividend date. Dividends, if any, are declared and distributed monthly for the Fund. The estimated characterization of the distributions paid will be either a qualified dividend or distribution (return of capital). This estimate is based on the Fund’s operating results during the period. It is anticipated that a significant portion of the distributions will be comprised of return of capital as a result of the tax character of cash distributions made by the Fund’s investments. The actual characterization of the distributions made during the period will not be determined until after the end of the fiscal year. The Fund will inform shareholders of the final tax character of the distributions on IRS Form 1099 DIV in February 2017. For the year ended November 30, 2016, the Fund distributions are expected to be comprised of 100% return of capital.

Return of Capital Estimates. Distributions received from the Fund’s investments in MLPs generally are comprised of income and return of capital. The Fund records investment income and return of capital based on estimates made at the time such distributions are received. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on information received from MLPs after their tax reporting periods are concluded. For the year ended November 30, 2016, the Fund estimated that 100% of the MLP distributions received would be treated as 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 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, if applicable, are amortized or accreted daily.

Custodian Fees. “Custody fees” 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

OPPENHEIMER STEELPATH MLP SELECT 40 FUND 25

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

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 using 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 Income Taxes. The Fund does not intend to qualify as a regulated investment company pursuant to Subchapter M of the Internal Revenue Code, but will rather be taxed as a corporation. As a corporation, the Fund is obligated to pay federal, state and local income tax on taxable income. Currently, the maximum marginal regular federal income tax rate for a corporation is 35 percent. Upon enactment, a change in the federal income tax rate could have a material impact to the Fund. The Fund may be subject to a 20 percent alternative minimum tax on its federal alternative minimum taxable income to the extent that its alternative minimum tax exceeds its regular federal income tax. The Fund is currently using an estimated rate of 1.7 percent for state and local tax, net of federal tax expense.

The Fund’s income tax provision consists of the following as of November 30, 2016:

Current tax expense (benefit)
Federal	$	—
State		—
Total current tax expense	$	—
Deferred tax expense (benefit)
Federal	$	98,347,279
State		4,776,868
Total deferred tax expense	$	103,124,147

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

The reconciliation between the federal statutory income tax rate of 35% and the effective tax rate on net investment income (loss) and realized and unrealized gain (loss) follows:

	Amount			Rate
Application of federal statutory income tax rate	$	100,410,387			35.00	%
State income taxes net of federal benefit		4,877,076			1.70	%
Effect of permanent differences		(2,163,316	)		(0.75	%)
Total income tax expense (benefit)	$	103,124,147			35.95	%

The Fund intends to invest its assets primarily in MLPs, which generally are treated as partnerships for federal income tax purposes. As a limited partner in the MLPs, the Fund reports its allocable share of the MLP’s taxable income in computing its own taxable income. The Fund’s tax expense or benefit will be included in the Statement of Operations based on the component of income or gains (losses) to which such expense or benefit relates. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Such temporary differences are principally: (i) taxes on unrealized gains/(losses), which are attributable to the temporary difference between fair market value and tax basis, (ii) the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes and (iii) the net tax benefit of accumulated net operating losses and capital loss carryforwards. Deferred tax assets and liabilities are measured using effective tax rates expected to apply to taxable income in the years such temporary differences are realized or otherwise settled. To the extent the Fund has a deferred tax asset, consideration is given to whether or not a valuation allowance is required. A valuation allowance is required if, based on the evaluation criterion provided by ASC 740, Income Taxes (ASC 740), it is more-likely-than-not some portion or all of the deferred tax asset will not be realized. Among the factors considered in assessing the Fund’s valuation allowance are: the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of the statutory carryforward periods, significant redemptions, and the associated risks that operating and capital loss carryforwards may expire unused.

At November 30, 2016, the Fund determined a valuation allowance was not required. In evaluating a valuation allowance on a portion of the deferred tax asset, significant consideration was given to the current and expected level of MLP distributions, unrealized gains and losses on MLP investments and the expiration dates for net operating losses and capital loss carryovers. Market cycles, the severity and duration of historical deferred tax assets and the impact of current and future redemptions were also considered. The Fund intends to assess whether a valuation allowance is required to offset some or all of any deferred tax asset balance in connection with the calculation of the Fund’s daily NAV; however, to the

OPPENHEIMER STEELPATH MLP SELECT 40 FUND 27

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

extent the final valuation allowance differs from the estimates of the Fund used in calculating the Fund’s daily NAV, the application of such final valuation allowance in these Financial Statements could have a material impact on the Fund’s NAV. Through the consideration of these factors, the Fund has determined that it is more likely than not the deferred tax asset, net of the valuation allowance, if required, will be realized.

Unexpected significant decreases in cash distributions from the Fund’s MLP investments, significant declines in the fair value of its investments, significant redemptions or increased risk of expiring net operating losses or capital loss carryovers may change the Fund’s assessment regarding the recoverability of its deferred tax assets and may result in a change to the valuation allowance. Modifications of the valuation allowance could have a material impact on the Fund’s net asset value.

Components of the Fund’s deferred tax assets and liabilities as of November 30, 2016 are as follows:

Deferred tax assets:
Net operating loss carryforward (tax basis)	$	190,460,705
Capital loss carryforward (tax basis)		40,614,150
Book to tax differences - Income recognized from MLPs		1,094,220
Organizational costs		7,648
Total deferred tax asset		232,176,723
Deferred tax liabilities:
Net unrealized gains on investment securities (tax basis)		(306,220,403	)
Total deferred tax liability		(306,220,403	)
Total net deferred tax asset/(liability)	$	(74,043,680	)

The Fund may rely, to some extent, on information provided by the MLPs, which may not necessarily be timely, to estimate taxable income allocable to MLP units held in its portfolio, and to estimate its associated deferred tax liability or asset. Such estimates are made in good faith. From time to time, as new information becomes available, the Fund will modify its estimates or assumptions regarding its tax liability or asset.

The Fund’s policy is to classify interest and penalties associated with underpayment of federal and state income taxes, if any, as income tax expense on its Statement of Operations. As of November 30, 2016, the Fund does not have any interest or penalties associated with the underpayment of any income taxes.

The Fund files income tax returns in the U.S. federal jurisdiction and various states. The Fund has reviewed all major jurisdictions and concluded that there is no significant impact on the Fund’s net assets and no tax liability resulting from unrecognized tax benefits relating to uncertain tax positions expected to be taken on its tax returns. Furthermore, management of the Fund is not aware of any uncertain tax positions for which it is reasonably possible that the total amount of unrecognized tax benefit will significantly change in the next 12 months.

At November 30, 2016, the Fund had net operating loss carryforwards for federal income tax purposes, which may be carried forward for 20 years, as follows:

Expiration Date
11/30/2030	$	525,993
11/30/2031		11,179,881
11/30/2032		33,698,662

11/30/2036		125,817,103
Total	$	518,965,777

At November 30, 2016, the Funds had net capital loss carryforwards for federal income tax purposes, which may be carried forward for 5 years, as follows:

Expiration Date
11/30/2021		110,665,259
Total	$	110,665,259

At November 30, 2016, gross unrealized appreciation and depreciation of investments, based on cost for federal income tax purposes were as follows:

Cost of Investments	$	2,301,371,175
Gross Unrealized Appreciation	$	1,049,704,859
Gross Unrealized Depreciation		(218,647,958	)
Net Unrealized Appreciation (Depreciation) on Investments	$	831,056,901

The difference between cost amounts for financial statement and federal income tax purposes is due primarily to timing differences in recognizing certain gains and losses in security transactions.

OPPENHEIMER STEELPATH MLP SELECT 40 FUND 29

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

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.

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, 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 of Trustees (the “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 Adviser. The Adviser 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:

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. If the official closing price or last sales 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) 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.

30 OPPENHEIMER STEELPATH MLP SELECT 40 FUND

NOTES TO FINANCIAL STATEMENTS (Continued)

3. Securities Valuation (Continued)

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 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.

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 Adviser, 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 Adviser’s Valuation Committee. The Valuation Committee considers all relevant facts that are reasonably available, through either public information or information available to the Adviser, when determining the fair value of a security. Fair value determinations by the Adviser 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

OPPENHEIMER STEELPATH MLP SELECT 40 FUND 31

NOTES TO FINANCIAL STATEMENTS (Continued)

3. Securities Valuation (Continued)

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 Adviser, or its third party service provider who is subject to oversight by the Adviser, 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.)

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

4. Investments and Risks

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

NOTES TO FINANCIAL STATEMENTS (Continued)

4. Investments and Risks (Continued)

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.

Master Limited Partnerships (“MLPs”). Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowings for investment purposes) in the equity securities of MLPs.

MLPs issue common units that represent an equity ownership interest in a partnership and provide limited voting rights. MLP common units are registered with the Securities and Exchange Commission (“SEC”), and are freely tradable on securities exchanges such as the NYSE and the NASDAQ Stock Market (“NASDAQ”), or in the over-the-counter (“OTC”) market. An MLP consists of one or more general partners, who conduct the business, and one or more limited partners, who contribute capital. MLP common unit holders have a limited role in the partnership’s operations and management. The Fund, as a limited partner, normally would not be liable for the debts of the MLP beyond the amounts the Fund has contributed, but would not be shielded to the same extent that a shareholder of a corporation would be. In certain circumstances creditors of an MLP would have the right to seek return of capital distributed to a limited partner. This right of an MLP’s creditors would continue after the Fund sold its investment in the MLP.

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

Concentration Risk. Under normal circumstances, the Fund invests at least 80% of its net assets (plus amounts of any borrowing for investment purposes) in the equity securities of MLPs. MLPs are subject to certain risks, such as supply and demand risk, depletion and exploration risk, commodity pricing risk, acquisition risk, and the risk associated with the hazards inherent in midstream energy industry activities. A substantial portion of the cash flow received by the Fund is derived from investment in equity securities of MLPs. The amount of cash that a MLP has available for distributions, and the tax character of such distributions, are dependent upon the amount of cash generated by the MLP’s operations.

5. Market Risk Factors

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

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

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

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

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

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

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

7. Purchases and Sales of Securities

The aggregate cost of purchases and proceeds from sales of securities, other than short-term obligations, for the year ended November 30, 2016, were as follows:

	Purchases		Sales
Investment securities	$	822,453,292	$	277,327,172

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:

Net Assets up to $3 Billion	Net Assets Greater than $3 Billion and up to $5 Billion	Net Assets in Excess of $5 Billion
0.70%	0.68%	0.65%

The Fund’s effective management fee for the year ended November 30, 2016 was 0.70% of average annual net assets before any applicable waivers.

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 with respect to these services are detailed in the Statement of Operations.

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 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

38 OPPENHEIMER STEELPATH MLP SELECT 40 FUND

NOTES TO FINANCIAL STATEMENTS (Continued)

8. Fees and Other Transactions with Affiliates (Continued)

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

Distribution and Service Plans for Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for distributing those share classes, maintaining accounts and providing shareholder services. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class C shares daily net assets. The Fund also pays a service fee under the Plans at an annual rate of 0.25% of daily net assets.

The Plan and Plans continue in effect from year to year only if the Fund’s Board votes annually to approve their continuance at an in person meeting called for that purpose. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations.

OPPENHEIMER STEELPATH MLP SELECT 40 FUND 39

NOTES TO FINANCIAL STATEMENTS (Continued)

8. Fees and Other Transactions with Affiliates (Continued)

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 C Contingent Deferred Sales Charges Retained by Distributor
November 30, 2016	$	278,818	$	79,925

Waivers and Reimbursements of Expenses. The Manager has contractually agreed to limit fees and/or reimburse expenses of the Fund to the extent that the Fund’s total annual fund operating expenses (exclusive of interest, taxes, such as deferred tax expenses, brokerage commissions, acquired fund fees and expenses, dividend costs related to short sales, and litigation expense, if any) exceed 1.10% for Class A shares, 1.85% for Class C shares, 0.85% for Class W shares, and 0.85% for Class Y shares.

The Fund’s total annual operating expenses after fee waiver and/or expense reimbursement (“Net Expenses”) will be higher than these amounts to the extent that the Fund incurs expenses excluded from the expense cap. Because the Fund’s deferred income tax expense/(benefit) and borrowing fees are excluded from the expense cap, the Fund’s Net Expenses for each class of shares is increased/(decreased) by the amount of this expense. During the year ended November 30, 2016, the Manager reimbursed $722,508, $569,794, $11,751, and $1,710,654 for Class A, Class C, Class W, and Class Y respectively. This undertaking may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein, unless approved by the Fund’s Board of Trustees.

The Manager can be reimbursed by the Fund within three years after the date the fee limitation and/or expense reimbursement has been made by the Manager, provided that such repayment does not cause the expenses of any class of the Fund to exceed the foregoing limits.

9. Borrowing Agreement

The Fund, along with Oppenheimer SteelPath MLP Alpha Plus Fund, Oppenheimer SteelPath MLP Income Fund, and Oppenheimer SteelPath MLP Alpha Fund (collectively, the “Trust”), is a borrower in a $700 million revolving credit agreement (“Loan Agreement”) with a major lending institution (the “Lender”). The Fund is permitted to borrow up to the lesser of one-third of the Fund’s total assets, or the maximum amount permitted pursuant to the Fund’s investment limitations. The borrowing, if any, is fully collateralized throughout the term of the borrowing with securities or other assets of the Fund. The Fund is not liable for borrowings of other Funds in the Trust. Securities that have been pledged as collateral for the borrowing are indicated in the Statement of Investments.

Borrowings under the Loan Agreement are charged interest at a calculated rate computed by the Lender based on the one month LIBOR rate plus 0.65% per annum. An unused commitment fee at the rate of 0.125% per annum is charged for any undrawn portion of the credit facility, and each member of the Trust will pay its pro rata share of this fee. A facility fee of 0.20% was charged on the commitment amount, and each party of the Trust paid its pro rata share of this fee. The borrowing is due November 17, 2017, unless another date is mutually agreed upon by the parties of the Loan Agreement. For the period ended November 30, 2016, the Fund paid $552,174 in borrowing fees. The Fund did not utilize the facility during the period ended November 30, 2016.

10. Pending Litigation

In 2009, several putative class action lawsuits were filed and later consolidated before the U.S. District Court for the District of Colorado in connection with the investment performance of Oppenheimer Rochester California Municipal Fund (the “California Fund”), a fund advised by OppenheimerFunds, Inc. (“OFI”) – the parent company of the manager and distributed by OppenheimerFunds Distributor, Inc. (“OFDI”) . The plaintiffs asserted claims against OFI, OFDI and certain present and former trustees and officers of the California Fund under the federal securities laws, alleging, among other things, that the disclosure documents of the California Fund contained misrepresentations and omissions and the investment policies of the California Fund were not followed. An amended complaint and a motion to dismiss were filed, and in 2011, the court issued an order which granted in part and denied in part the defendants’ motion to dismiss. In October 2015, following a successful appeal by defendants and a subsequent hearing, the court granted plaintiffs’ motion for class certification and appointed class representatives and class counsel.

OFI and OFDI believe the suit is without merit; that it is premature to render any opinion as to the likelihood of an outcome unfavorable to them in the Suit; and that no estimate can yet be made as to the amount or range of any potential loss. Furthermore, OFI believes that the suit should not impair the ability of OFI or OFDI to perform their respective duties to the Fund and that the outcome of the suit should not have any material effect on the operations of any of the Oppenheimer funds.

We have audited the accompanying statement of assets and liabilities, including the statement of investments, of Oppenheimer SteelPath MLP Select 40 Fund (the “Fund”), a series of Oppenheimer SteelPath MLP Funds Trust, as of November 30, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of November 30, 2016, by correspondence with the custodian and brokers or by other auditing procedures as appropriate in the circumstances. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Oppenheimer SteelPath MLP Select 40 Fund as of November 30, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

BOARD APPROVAL OF THE FUND’S INVESTMENT
ADVISORY AGREEMENT Unaudited

The Fund has entered into an investment advisory agreement (the “Agreement”) with OFI SteelPath, Inc. (“OFI SteelPath” or the “Manager”). Each year, the Board of Trustees (the “Board”), including a majority of the independent Trustees, is required to determine whether to approve the terms of the Agreement and the renewal thereof. The Investment Company Act of 1940, as amended, requires that the Board request and evaluate, and that the Manager provide, such information as may be reasonably necessary to evaluate the terms of the Agreement. The Board employs an independent consultant to prepare a report that provides information, including comparative information that the Board requests for that purpose. In addition to in-person meetings focused on this evaluation, the Board receives information throughout the year regarding Fund services, fees, expenses and performance.

The Manager and the independent consultant provided information to the Board on the following factors: (i) the nature, quality and extent of the Manager’s services, (ii) the comparative investment performance of the Fund and the Manager, (iii) the fees and expenses of the Fund, including comparative fee and expense information, (iv) the profitability of the Manager and its 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 Manager from its relationship with the Fund. The Board was aware that there are alternatives to retaining the Manager.

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 Manager’s key personnel who provide such services. The Manager’s duties include providing the Fund with the services of the portfolio managers and investment team, who provide research, analysis and other advisory services in regard to the Fund’s investments; and securities trading services. The Manager is responsible for 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 Manager is also responsible for providing certain administrative services to the Fund. Those services, some of which are performed by affiliates of the Manager, 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 U.S. Securities and Exchange Commission; preparing periodic reports regarding the operations of the Fund for its shareholders; preparing proxy materials for shareholder meetings; and preparing the registration statements required by federal and state securities laws for the sale of the Fund’s shares. The Manager also provides the Fund with office space, facilities and equipment.

BOARD APPROVAL OF THE FUND’S INVESTMENT
ADVISORY AGREEMENT Unaudited / (Continued)

The Board also considered the quality of the services provided and the quality of the Manager’s resources that are available to the Fund. In evaluating the Manager, the Board considered the history, reputation, qualification and background of the Manager, including its corporate parent, OppenheimerFunds, Inc. (“OFI”) and corporate affiliate, OFI Global Asset Management, Inc. (“OFI Global” and OFI and OFI Global are collectively referred to hereinafter as “OFI”), and the fact that OFI has over 50 years of experience as an investment adviser and that its assets under management rank it among the top mutual fund managers in the United States. The Board evaluated the Manager’s and OFI’s advisory, administrative, accounting, legal, compliance and risk management services, and information the Board has received regarding the experience and professional qualifications of the Manager’s and OFI’s 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 Stuart Cartner and Brian Watson, the portfolio managers for the Fund, and the Manager’s investment team and analysts. The Board members also considered the totality of their experiences with the Manager and OFI as trustees of the Fund and other funds advised by the Manager or OFI. The Board considered information regarding the quality of services provided by affiliates of the Manager, which the Board members have become knowledgeable about through their experiences with the Manager or OFI and in connection with the renewal of the Fund’s service agreements. The Board concluded, in light of the Manager’s and OFI’s experience, reputation, personnel, operations and resources that the Fund benefits from the services provided under the Agreement.

Investment Performance of the Manager and the Fund. Throughout the year, the Manager provided information on the investment performance of the Fund and the Manager, including comparative performance information. The Board also reviewed information, prepared by the Manager and by the independent consultant, comparing the Fund’s historical performance to relevant market indices and to the performance of other retail energy limited partnership funds. The Board noted that the Fund outperformed its category median for the one-, three- and five-year periods.

Fees and Expenses of the Fund. The Board reviewed the fees paid to the Manager and the other expenses borne by the Fund. The independent consultant provided comparative data in regard to the fees and expenses of the Fund and other retail energy limited partnership funds with comparable asset levels and distribution features. The Board noted that the Fund’s contractual management fee and its total expenses were lower than their respective peer group medians and category medians. The Board considered that the Manager has contractually agreed to waive fees and/or reimburse the Fund so that total expenses, as a percentage of average daily net assets, will not exceed the following annual rates: 1.10% for Class A shares, 1.85% for Class C shares, and 0.85% for Class Y shares and Class W shares. The fee limitation may not be amended or withdrawn prior to March 30, 2017, unless approved by the Board.

ADVISORY AGREEMENT Unaudited / (Continued)

Economies of Scale and Profits Realized by the Manager. The Board considered information regarding the Manager’s costs in serving as the Fund’s investment adviser, including the costs associated with the personnel and systems necessary to manage the Fund, and information regarding the Manager’s profitability from its relationship with the Fund. The Board also considered that the Manager must be able to pay and retain experienced professional personnel at competitive rates to provide quality services to the Fund. The Board reviewed whether the Manager may 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 Manager. In addition to considering the profits realized by the Manager, the Board considered information that was provided regarding the direct and indirect benefits the Manager receives as a result of its relationship with the Fund, including compensation paid to the Manager’s affiliates and research provided to the Manager in connection with permissible brokerage arrangements (soft dollar arrangements).

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 Manager within the meaning and intent of the Securities and Exchange Commission Rules.

Based on its review of the information it received and its evaluations described above, the Board, including a majority of the independent Trustees, decided to continue the Agreement through August 31, 2017. 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 Agreement, including the management fees, in light of all the surrounding circumstances.

For any distribution that took place over the last six months of the Fund’s reporting period, the table below details, on a per-share basis, the percentage of the Fund’s total distribution payment amount that was derived from the following sources: net income, net profit from the sale of securities, and other capital sources. This information is based upon income and capital gains using generally accepted accounting principles as of the date of each distribution. For certain securities, such as Master Limited Partnerships (“MLPs”), the percentages attributed to each category are estimated using historical information because the character of the amounts received from the MLPs in which the Fund invests is unknown until after the end of the calendar year. Because the Fund is actively managed, the relative amount of the Fund’s total distributions derived from various sources over the calendar year may change. Please note that this information should not be used for tax reporting purposes as the tax character of distributable income may differ from the amounts used for this notification. You will receive IRS tax forms in the first quarter of each calendar year detailing the actual amount of the taxable and non-taxable portion of distributions paid to you during the tax year.

For the most current information, please go to oppenheimerfunds.com. Select your Fund, then the ’Detailed’ tab; where ‘Dividends’ are shown, the Fund’s latest pay date will be followed by the sources of any distribution, updated daily.

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.

Fund Performance Discussion

The Fund’s Class A shares (without sales charge) produced a total return of 5.25% during the reporting period. In comparison, master limited partnerships (“MLPs”), as measured by the Alerian MLP Index (AMZ), provided a total return gain of 9.28%. Please note that the returns for the Alerian MLP Index are calculated pre-tax, while the Fund’s returns are calculated post corporate tax. During the same period, the S&P 500 Index produced a total return gain of 8.06%.

Over the twelve-month reporting period ended November 30, 2016, the midstream sector outperformed the broader markets as the lows of the current energy cycle appear to have been reached and the beginnings of a recovery appear to be unfolding. Late in the period, the Organization of Petroleum Exporting Countries (“OPEC”) provided a potential acceleration to the rebalancing of crude oil supply and demand by announcing formal plans to reduce its production to 32.5 million barrels of oil per day (MMbbls/d) by January 2017. Agreements with non-OPEC countries to provide additional support via another 0.6 MMbbls/d of supply reductions were also announced, most notably with Russia electing to reduce production by 0.3 MMbbls/d. The larger than expected supply reduction sent oil prices sharply higher and many energy equities even more so. This reduced supply from OPEC members will pull the consensus estimates for the 2017 oil market balance back firmly into an undersupplied position, thereby beginning the process of working down

OPPENHEIMER STEELPATH MLP ALPHA FUND 3

global inventories. And, importantly for U.S. midstream investors, the OPEC cut helps reduce the market forces that were driving near-term U.S. production, and thus midstream throughput, lower. Further, we continue to believe that this energy down cycle has shifted the call on U.S.-sourced volumes higher over the medium-term. This improving fundamental commodity picture, combined with midstream valuations that remain below long-term averages, makes a compelling case for midstream investment.

Over the reporting period, we estimate approximately $26 billion of new equity supply entered the market through either secondary offerings, initial public offerings, or “at-the-market” programs in which primary units trade into the market anonymously throughout the normal trading day. This pace of equity issuance represents an increase from approximately $20 billion that was raised over the twelve month reporting period ended November 30, 2015. MLPs also raised approximately $23 billion of debt capital during the period. Most MLPs pay out the majority of excess cash flow as distributions to investors, and therefore must raise external capital to fund growth projects and to fund acquisitions.

MACRO REVIEW

West Texas Intermediate (WTI) crude oil prices ended the reporting period at $49.44 per barrel, up 19% from the prior year. Global crude prices, as measured by Brent crude oil, traded 13% higher over the reporting period. The crude oil price improvement appears linked to the continued moderation in U.S. crude production, healthy demand growth, and the aforementioned OPEC deal to reduce supply. Brent exited the period at a $1 per barrel premium to WTI, which is near the historic norm. However, this reversion represents a departure from the $8 to $9 per barrel Brent premium that has generally existed since 2009.

Henry Hub natural gas spot prices exited the period at $3.30 per million British thermal units (“mmbtu”), up 58% over the reporting period. Natural gas pricing has benefited from a long awaited realignment of supply-demand in which natural gas usage as a heating and electric generation fuel has increased as gas production volume growth has declined, and as increased exports have become a reality via both liquefied natural gas and new pipelines to Mexico.

Mont Belvieu NGL prices ended the reporting period at $23.92 per barrel, a 26% increase over the reporting period. All of the NGL purity products ended the period higher than the same time in the prior year. Frac spreads, a measure of natural gas processing economics, ended the period at $0.28 per gallon, up 4% over the reporting period. Generally, the greater the frac spread, the greater the incentive for producers to seek natural gas processing capacity.

The yield curve modestly flattened over the reporting period as short rates rose more than the yields on longer-dated maturities. The ten-year Treasury yield rose 18 basis points to end the period at 2.38%. The MLP yield spread at period-end, as

4 OPPENHEIMER STEELPATH MLP ALPHA FUND

measured by the AMZ and the 10-year Treasury bond, narrowed by 115 basis points to 5.05%.

Over the reporting period, real estate investment trusts (“REITs”) and utilities, two competing yield-oriented equity asset classes, posted total returns of 5.65% (as measured by the Dow Jones Equity REIT Total Return Index) and 16.31% (as measured by the Dow Jones Utility Average Index), respectively, as compared to the AMZ’s 9.28% total return. Price to forward distributable cash flow (DCF), a commonly watched ratio within the MLP sector, increased over the period but remains below the ten-year average.

SUBSECTOR REVIEW

Performance among subsectors in the midstream, or energy infrastructure, MLP asset class varied for the reporting period. On average, the gathering and processing subsector provided the best performance over the period, buoyed by improving commodity prices supporting improved volumetric projections. The natural gas pipeline group followed as investors continued to express preference for long-haul natural gas pipelines, particularly those backed by utility demand pull.

The marine subsector experienced the weakest performance over the reporting period as several entities substantially reduced cash distributions to investors. The propane subsector also lagged over the reporting period as market participants appeared to rotate out of the subsector in favor of more traditional midstream names and as rising propane prices could result in some margin pressure in future periods.

FUND REVIEW

Key contributors to the Fund were Williams Partners, LP (WPZ) and Tallgrass Energy GP, LP (TEGP).

WPZ units outperformed over the period after the proposed merger with Energy Transfer was terminated in late June and the Williams enterprise subsequently focused on strengthening its balance sheet, improving liquidity, and preserving its investment grade credit rating. During the period The Williams Companies (WMB) began execution of plans to reinvest $1.7 billion into WPZ, its daughter partnership, via a private purchase of common units and a concurrently announced distribution reinvestment program (“DRIP”). The Williams family also announced a restructuring of gathering agreements that served to reduce counterparty risk and the sale of Canadian assets that raised $1 billion in cash proceeds.

TEGP units outperformed over the period as the general partner’s underlying operating partnership, Tallgrass Energy Partners (TEP), reaffirmed annual distribution growth guidance of at least 20% for the period of 2015 through 2017. Additionally, the partnership’s sponsor announced an agreement to acquire additional interests in the Rockies Express Pipeline, which aids longer-term growth prospects. Notably, TEGP’s board approved a $100 million buyback program of TEP or TEGP units.

OPPENHEIMER STEELPATH MLP ALPHA FUND 5

Key detractors from the Fund were Energy Transfer Equity LP (ETE) and The Williams Companies (WMB).

Both ETE and WMB units detracted from performance over the reporting period on investor concern over the planned merger of ETE and WMB. After the merger was terminated in late June, each entity executed measures to support their respective daughter partnerships, some at the expense of current parent cash flows. While the equity price performance of both entities lagged over the reporting period, each has recovered substantially from the lows.

Please note that significant decreases in cash distributions from the Fund’s MLP investments and/or significant declines in the fair value of its investments may impact the Fund’s assessment regarding the recoverability of certain deferred tax assets, which may result in the recording of a valuation allowance. If a valuation allowance is established, this could have a material impact on the Fund’s net asset value and results of operations for the period. The Fund had a valuation allowance in place for a portion of the reporting period, but did not have one in place at period end. See Note 2 of the Notes to Financial Statements for more information.

OUTLOOK

We believe we have seen the worst of this energy market down cycle. The rate of midstream growth will likely moderate from peak levels, but average distributions are still likely to grow. Midstream operators may also stand to benefit as they make more efficient use of their existing assets. We believe current market valuations underestimate the potential for renewed business growth going forward and remain optimistic on the sector’s prospects. For this reason, we believe MLPs continue to offer attractive total return potential based on the potential for price appreciation and stable or growing distribution streams.

The Fund’s performance is compared to the performance of the S&P 500 Index and the Alerian MLP Index. The S&P 500 Index is a broad-based measure of domestic stock performance. The Alerian MLP Index is a composite of the 50 most prominent Master Limited Partnerships that provides investors with an unbiased, comprehensive benchmark for this emerging asset class. The Alerian MLP Index, which is calculated using a float-adjusted, capitalization-weighted methodology, is disseminated real-time on a total-return basis. The indices are 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 indices. Index performance includes reinvestment of income, but does not reflect transaction costs, fees, expenses or

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 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 November 30, 2016.

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 November 30, 2016” 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). 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	999.00	25.99
CLASS Y	1,000.00	998.53	26.45

Expenses are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 183/366 (to reflect the one-half year period). Those annualized expense ratios, excluding indirect expenses from affiliated funds, based on the 6-month period ended November 30, 2016 are as follows:

Class	Expense Ratios
CLASS A	5.54%
CLASS C	6.29
CLASS I	5.20
CLASS Y	5.29

The expense ratios for Class A, C, and Y reflect 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, if applicable.

OPPENHEIMER STEELPATH MLP ALPHA FUND 21

NOTES TO FINANCIAL STATEMENTS

1. Organization

Oppenheimer SteelPath MLP Alpha Fund (the “Fund”), a separate series of Oppenheimer SteelPath MLP Funds Trust, is a non-diversified open-end management investment company registered under the Investment Company Act of 1940, as amended. The Fund’s investment objective is to seek total return. The Fund’s investment adviser is OFI SteelPath, Inc. (the “Adviser” or “Manager”), a wholly-owned subsidiary of OppenheimerFunds, Inc. (“OFI” or “Oppenheimer”).

The Fund offers Class A, Class C, Class I, and Class Y shares. Effective June 28, 2013, Class I shares were renamed Class Y shares. Class A shares are sold at their offering price, which is normally net asset value plus a front-end sales charge. Effective June 28, 2013 although there is no initial sales charge on Class A purchases totaling $1 million or more, those Class A shares may be subject to a 1.00% contingent deferred sales charge (“CDSC”) if shares are redeemed within an 18-month “holding period” measured from the date of purchase. Class C shares are sold without a front-end sales charge but may be subject to a CDSC of 1.00% of the redemption proceeds if Class C shares are redeemed within one year of purchase. Class I shares are only available to eligible institutional investors. Class I shares are sold at net asset value per share without a sales charge or CDSC. An institutional investor that buys Class I shares for its customers’ accounts may impose charges on those accounts. Class Y shares are sold at net asset value per share without a sales charge directly to institutional investors that have special agreements with OppenheimerFunds Distributor, Inc. (the “Distributor) for that purpose. They may include insurance companies, registered investment companies, employee benefit plans and section 529 plans, among others. An institutional investor that buys Class Y shares for its customers’ accounts may impose charges on those accounts. All classes of shares have identical rights and voting privileges with respect to the Fund in general and exclusive voting rights on matters that affect that class alone. Earnings, net assets and net asset value per share may differ due to each class having its own expenses, such as transfer and shareholder servicing agent fees and shareholder communications, directly attributable to that class. Class A and C shares have separate distribution and/or service plans under which they pay fees. Class I and Y shares do not pay such fees.

The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification Topic 946 Financial Services- Investment Companies.

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. generally accepted accounting principles, are recorded on the ex-dividend date. Dividends, if any, are declared and distributed monthly for the Fund. The estimated characterization of the distributions paid will be either a qualified dividend or distribution (return of capital). This estimate is based on the Fund’s operating results during the period. It is anticipated that a significant portion of the distributions will be comprised of return of capital as a result of the tax character of cash distributions made by the Fund’s investments. The actual characterization of the distributions made during the period will not be determined until after the end of the fiscal year. The Fund will inform shareholders of the final tax character of the distributions on IRS Form 1099 DIV in February 2017. For the year ended November 30, 2016, the Fund distributions are expected to be comprised of 100% return of capital.

Return of Capital Estimates. Distributions received from the Fund’s investments in MLPs generally are comprised of income and return of capital. The Fund records investment income and return of capital based on estimates made at the time such distributions are received. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on information received from MLPs after their tax reporting periods are concluded. For the year ended November 30, 2016, the Fund estimated that 100% of the MLP distributions received would be treated as 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 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, if applicable, are amortized or accreted daily.

Custodian Fees. “Custody fees” 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 using 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 Income Taxes. The Fund does not intend to qualify as a regulated investment company pursuant to Subchapter M of the Internal Revenue Code, but will rather be taxed as a corporation. As a corporation, the Fund is obligated to pay federal, state and local income tax on taxable income. Currently, the maximum marginal regular federal income tax rate for a corporation is 35 percent. Upon enactment, a change in the federal income tax rate could have a material impact to the Fund. The Fund may be subject to a 20 percent alternative minimum tax on its federal alternative minimum taxable income to the extent that its alternative minimum tax exceeds its regular federal income tax. The Fund is currently using an estimated rate of 1.7 percent for state and local tax, net of federal tax expense.

The Fund’s income tax provision consists of the following as of November 30, 2016:

Current tax expense (benefit)
Federal	$	—
State		—
Total current tax expense	$	—
Deferred tax expense (benefit)
Federal	$	77,627,185
State		4,412,938
Total deferred tax expense	$	82,040,123

The reconciliation between the federal statutory income tax rate of 35% and the effective tax rate on net investment income (loss) and realized and unrealized gain (loss) follows:

	Amount			Rate
Application of federal statutory income tax rate	$	80,315,926			35.00	%
State income taxes net of federal benefit		3,901,059			1.70	%
Effect of state tax rate change		642,475			0.28	%
Effect of permanent differences		(2,819,337	)		(1.23	%)
Total income tax expense (benefit)	$	82,040,123			35.75	%

The Fund intends to invest its assets primarily in MLPs, which generally are treated as partnerships for federal income tax purposes. As a limited partner in the MLPs, the Fund reports its allocable share of the MLP’s taxable income in computing its own taxable income. The Fund’s tax expense or benefit will be included in the Statement of Operations based on the component of income or gains (losses) to which such expense or benefit relates. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Such temporary differences are principally: (i) taxes on unrealized gains/(losses), which are attributable to the temporary difference between fair market value and tax basis, (ii) the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes and (iii) the net tax benefit of accumulated net operating losses and capital loss carryforwards. Deferred tax assets and liabilities are measured using effective tax rates expected to apply to taxable income in the years such temporary differences are realized or otherwise settled. To the extent the Fund has a deferred tax asset, consideration is given to whether or not a valuation allowance is required. A valuation allowance is required if, based on the evaluation criterion provided by ASC 740, Income Taxes (ASC 740), it is more-likely-than-not some portion or all of the deferred tax asset will not be realized. Among the factors considered in assessing the Fund’s valuation allowance are: the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of the statutory carryforward periods, significant redemptions, and the associated risks that operating and capital loss carryforwards may expire unused.

At November 30, 2016, the Fund determined a valuation allowance was not required. In evaluating a valuation allowance on a portion of the deferred tax asset, significant consideration was given to the current and expected level of MLP distributions, unrealized gains and losses on MLP investments and the expiration dates for net operating losses and capital loss carryovers. Market cycles, the severity and duration of historical deferred tax assets and the impact of current and future redemptions were also considered. The Fund intends to assess whether a valuation allowance is required to offset some or all of any deferred tax asset balance in connection with the calculation of the Fund’s daily NAV; however, to the

OPPENHEIMER STEELPATH MLP ALPHA FUND 25

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

extent the final valuation allowance differs from the estimates of the Fund used in calculating the Fund’s daily NAV, the application of such final valuation allowance in these Financial Statements could have a material impact on the Fund’s NAV. Through the consideration of these factors, the Fund has determined that it is more likely than not the deferred tax asset, net of the valuation allowance, if required, will be realized.

Unexpected significant decreases in cash distributions from the Fund’s MLP investments, significant declines in the fair value of its investments, significant redemptions or increased risk of expiring net operating losses or capital loss carryovers may change the Fund’s assessment regarding the recoverability of its deferred tax assets and may result in a change to the valuation allowance. Modifications of the valuation allowance could have a material impact on the Fund’s net asset value.

Components of the Fund’s deferred tax assets and liabilities as of November 30, 2016 are as follows:

Deferred tax assets:
Net operating loss carryforward (tax basis)	$	155,676,320
Capital loss carryforward (tax basis)		286,712,630
Book to tax differences - Income recognized from MLPs		11,193,901
Total deferred tax asset		453,582,851
Deferred tax liabilities:
Net unrealized gains on investment securities (tax basis)		(292,212,410	)
Total deferred tax liability		(292,212,410	)
Total net deferred tax asset/(liability)	$	161,370,441

The Fund may rely, to some extent, on information provided by the MLPs, which may not necessarily be timely, to estimate taxable income allocable to MLP units held in its portfolio, and to estimate its associated deferred tax liability or asset. Such estimates are made in good faith. From time to time, as new information becomes available, the Fund will modify its estimates or assumptions regarding its tax liability or asset.

The Fund’s policy is to classify interest and penalties associated with underpayment of federal and state income taxes, if any, as income tax expense on its Statement of Operations. As of November 30, 2016, the Fund does not have any interest or penalties associated with the underpayment of any income taxes.

The Fund files income tax returns in the U.S. federal jurisdiction and various states. The Fund has reviewed all major jurisdictions and concluded that there is no significant impact on the Fund’s net assets and no tax liability resulting from unrecognized tax benefits relating to

26 OPPENHEIMER STEELPATH MLP ALPHA FUND

2. Significant Accounting Policies (Continued)

uncertain tax positions expected to be taken on its tax returns. Furthermore, management of the Fund is not aware of any uncertain tax positions for which it is reasonably possible that the total amount of unrecognized tax benefit will significantly change in the next 12 months.

At November 30, 2016, the Fund had net operating loss carryforwards for federal income tax purposes, which may be carried forward for 20 years, as follows:

Expiration Date
11/30/2030	$	1,194,164
11/30/2031		7,264,183
11/30/2032		34,906,904
11/30/2033		59,435,302
11/30/2034		89,553,891
11/30/2035		148,345,011
11/30/2036		83,486,702
Total	$	424,186,157

At November 30, 2016, the Fund had net capital loss carryforwards for federal income tax purposes, which may be carried forward for 5 years, as follows:

Expiration Date
11/30/2020	$	201,946,664
11/30/2021		579,286,660
Total	$	781,233,324

At November 30, 2016, gross unrealized appreciation and depreciation of investments, based on cost for federal income tax purposes were as follows:

Cost of Investments	$	2,532,934,397
Gross Unrealized Appreciation	$	1,040,605,954
Gross Unrealized Depreciation		(242,434,367	)
Net Unrealized Appreciation (Depreciation) on Investments	$	798,171,587

The difference between cost amounts for financial statement and federal income tax purposes is due primarily to timing differences in recognizing certain gains and losses in security transactions.

OPPENHEIMER STEELPATH MLP ALPHA FUND 27

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

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.

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 of Trustees (the “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 Adviser. The Adviser 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:

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. If the official closing price or last sales 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) 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.

28 OPPENHEIMER STEELPATH MLP ALPHA FUND

NOTES TO FINANCIAL STATEMENTS (Continued)

3. Securities Valuation (Continued)

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 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.

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

OPPENHEIMER STEELPATH MLP ALPHA FUND 29

NOTES TO FINANCIAL STATEMENTS (Continued)

3. Securities Valuation (Continued)

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.)

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.

There have been no transfers between pricing levels for the Fund. It is the Fund’s policy to recognize transfers at the beginning of the reporting period.

4. Investments and Risks

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

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

Master Limited Partnerships (“MLPs”). Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowings for investment purposes) in the equity securities of MLPs.

OPPENHEIMER STEELPATH MLP ALPHA FUND 31

NOTES TO FINANCIAL STATEMENTS (Continued)

4. Investments and Risks (Continued)

MLPs issue common units that represent an equity ownership interest in a partnership and provide limited voting rights. MLP common units are registered with the Securities and Exchange Commission (“SEC”), and are freely tradable on securities exchanges such as the NYSE and the NASDAQ Stock Market (“NASDAQ”), or in the over-the-counter (“OTC”) market. An MLP consists of one or more general partners, who conduct the business, and one or more limited partners, who contribute capital. MLP common unit holders have a limited role in the partnership’s operations and management. The Fund, as a limited partner, normally would not be liable for the debts of the MLP beyond the amounts the Fund has contributed, but would not be shielded to the same extent that a shareholder of a corporation would be. In certain circumstances creditors of an MLP would have the right to seek return of capital distributed to a limited partner. This right of an MLP’s creditors would continue after the Fund sold its investment in the MLP.

Concentration Risk. Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowing for investment purposes) in the equity securities of MLPs. MLPs are subject to certain risks, such as supply and demand risk, depletion and exploration risk, commodity pricing risk, acquisition risk, and the risk associated with the hazards inherent in midstream energy industry activities. A substantial portion of the cash flow received by the Fund is derived from investment in equity securities of MLPs. The amount of cash that a MLP has available for distributions, and the tax character of such distributions, are dependent upon the amount of cash generated by the MLP’s operations.

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.

32 OPPENHEIMER STEELPATH MLP ALPHA FUND

NOTES TO FINANCIAL STATEMENTS (Continued)

5. Market Risk Factors (Continued)

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

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

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

6. Shares of Beneficial Interest

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

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:

Net Assets up to $3 Billion	Net Assets Greater than $3 Billion and up to $5 Billion	Net Assets in Excess of $5 Billion
1.10%	1.08%	1.05%

The Fund’s effective management fee for the year ended November 30, 2016 was 1.10% of average annual net assets before any applicable waivers.

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 with respect to these services are detailed in the Statement of Operations.

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 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, if applicable. 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, the Distributor acts as the Fund’s principal underwriter in the continuous public offering of the Fund’s classes of shares.

OPPENHEIMER STEELPATH MLP ALPHA FUND 35

NOTES TO FINANCIAL STATEMENTS (Continued)

8. Fees and Other Transactions with Affiliates (Continued)

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

Distribution and Service Plans for Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for distributing those share classes, maintaining accounts and providing shareholder services. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class C shares daily net assets. The Fund also pays a service fee under the Plans at an annual rate of 0.25% of daily net assets.

The Plan and Plans continue in effect from year to year only if the Fund’s Board votes annually to approve their continuance at an in person meeting called for that purpose. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations.

Sales Charges. Front-end sales charges and contingent deferred sales charges (“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
November 30, 2016	$	492,043	$	29,915	$	96,191

Waivers and Reimbursements of Expenses. The Manager has contractually agreed to limit fees and/or reimburse expenses of the Fund to the extent that the Fund’s total annual fund operating expenses (exclusive of interest, taxes, such as deferred tax expenses,

brokerage commissions, acquired fund fees and expenses, dividend costs related to short sales, and litigation expense, if any) exceed 1.50% for Class A shares, 2.25% for Class C shares, and 1.25% for Class Y shares.

The Fund’s total annual operating expenses after fee waiver and/or expense reimbursement (“Net Expenses”) will be higher than these amounts to the extent that the Fund incurs expenses excluded from the expense cap. Because the Fund’s deferred income tax expense/(benefit) and borrowing fees are excluded from the expense cap, the Fund’s Net Expenses for each class of shares is increased/(decreased) by the amount of this expense. During the year ended November 30, 2016, the Manager reimbursed $1,177,180, $816,992, and $1,617,340 for Class A, Class C, and Class Y, respectively. This undertaking may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein, unless approved by the Fund’s Board.

The Manager can be reimbursed by the Fund within three years after the date the fee limitation and/or expense reimbursement has been made by the Manager, provided that such repayment does not cause the expenses of any class of the Fund to exceed the foregoing limits.

The following table represents amounts eligible for recovery at November 30, 2016:

Eligible Expense Recoupment Expiring:
November 30, 2017	$	4,876,625
November 30, 2018		4,954,289
November 30, 2019		3,611,512

During the year ended November 30, 2016, the Adviser did not recoup any expenses.

9. Borrowing Agreement

The Fund, along with Oppenheimer SteelPath MLP Alpha Plus Fund, Oppenheimer SteelPath MLP Income Fund, and Oppenheimer SteelPath MLP Select 40 Fund (collectively, the “Trust”), is a borrower in a $700 million revolving credit agreement (the “Loan Agreement”) with a major lending institution (the “Lender”). The Fund is permitted to borrow up to the lesser of one-third of the Fund’s total assets, or the maximum amount permitted pursuant to the Fund’s investment limitations. The borrowing, if any, is fully collateralized throughout the term of the borrowing with securities or other assets of the Fund. The Fund is not liable for borrowings of other Funds in the Trust. Securities that have been pledged as collateral for the borrowing are indicated in the Statement of Investments.

9. Borrowing Agreement (Continued)

Borrowings under the Loan Agreement are charged interest at a calculated rate computed by the Lender based on the one month LIBOR rate plus 0.65% per annum. An unused commitment fee at the rate of 0.125% per annum is charged for any undrawn portion of the credit facility, and each member of the Trust will pay its pro rata share of this fee. A facility fee of 0.20% was charged on the commitment amount, and each party of the Trust paid its pro rata share of this fee. The borrowing is due November 17, 2017, unless another date is mutually agreed upon by the parties of the Loan Agreement. For the year ended November 30, 2016, the Fund paid $714,275 in borrowing fees. The Fund did not utilize the facility during the year ended November 30, 2016.

10. Pending Litigation

In 2009, several putative class action lawsuits were filed and later consolidated before the U.S. District Court for the District of Colorado in connection with the investment performance of Oppenheimer Rochester California Municipal Fund (the “California Fund”), a fund advised by OppenheimerFunds, Inc. (“OFI”) – the parent company of the manager and distributed by OppenheimerFunds Distributor, Inc. (“OFDI”). The plaintiffs asserted claims against OFI, OFDI and certain present and former trustees and officers of the California Fund under the federal securities laws, alleging, among other things, that the disclosure documents of the California Fund contained misrepresentations and omissions and the investment policies of the California Fund were not followed. An amended complaint and a motion to dismiss were filed, and in 2011, the court issued an order which granted in part and denied in part the defendants’ motion to dismiss. In October 2015, following a successful appeal by defendants and a subsequent hearing, the court granted plaintiffs’ motion for class certification and appointed class representatives and class counsel.

OFI and OFDI believe the suit is without merit; that it is premature to render any opinion as to the likelihood of an outcome unfavorable to them in the Suit; and that no estimate can yet be made as to the amount or range of any potential loss. Furthermore, OFI believes that the suit should not impair the ability of OFI or OFDI to perform their respective duties to the Fund and that the outcome of the suit should not have any material effect on the operations of any of the Oppenheimer funds.

These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of November 30, 2016, by correspondence with the custodian and brokers or by other auditing procedures as appropriate in the circumstances. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Oppenheimer SteelPath MLP Alpha Fund as of November 30, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

BOARD APPROVAL OF THE FUND’S INVESTMENT
ADVISORY AGREEMENT Unaudited

The Fund has entered into an investment advisory agreement (the “Agreement”) with OFI SteelPath, Inc. (“OFI SteelPath” or the “Manager”). Each year, the Board of Trustees (the “Board”), including a majority of the independent Trustees, is required to determine whether to approve the terms of the Agreement and the renewal thereof. The Investment Company Act of 1940, as amended, requires that the Board request and evaluate, and that the Manager provide, such information as may be reasonably necessary to evaluate the terms of the Agreement. The Board employs an independent consultant to prepare a report that provides information, including comparative information that the Board requests for that purpose. In addition to in-person meetings focused on this evaluation, the Board receives information throughout the year regarding Fund services, fees, expenses and performance.

The Manager and the independent consultant provided information to the Board on the following factors: (i) the nature, quality and extent of the Manager’s services, (ii) the comparative investment performance of the Fund and the Manager, (iii) the fees and expenses of the Fund, including comparative fee and expense information, (iv) the profitability of the Manager and its 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 Manager from its relationship with the Fund. The Board was aware that there are alternatives to retaining the Manager.

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 Manager’s key personnel who provide such services. The Manager’s duties include providing the Fund with the services of the portfolio managers and investment team, who provide research, analysis and other advisory services in regard to the Fund’s investments; and securities trading services. The Manager is responsible for 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 Manager is also responsible for providing certain administrative services to the Fund. Those services, some of which are performed by affiliates of the Manager, 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 U.S. Securities and Exchange Commission; preparing periodic reports regarding the operations of the Fund for its shareholders; preparing proxy materials for shareholder meetings; and preparing the registration statements required by federal and state securities laws for the sale of the Fund’s shares. The Manager also provides the Fund with office space, facilities and equipment.

ADVISORY AGREEMENT Unaudited / (Continued)

The Board also considered the quality of the services provided and the quality of the Manager’s resources that are available to the Fund. In evaluating the Manager, the Board considered the history, reputation, qualification and background of the Manager, including its corporate parent, OppenheimerFunds, Inc. (“OFI”) and corporate affiliate, OFI Global Asset Management, Inc. (“OFI Global” and OFI and OFI Global are collectively referred to hereinafter as “OFI”), and the fact that OFI has over 50 years of experience as an investment adviser and that its assets under management rank it among the top mutual fund managers in the United States. The Board evaluated the Manager’s and OFI’s advisory, administrative, accounting, legal, compliance and risk management services, and information the Board has received regarding the experience and professional qualifications of the Manager’s and OFI’s 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 Stuart Cartner and Brian Watson, the portfolio managers for the Fund, and the Manager’s investment team and analysts. The Board members also considered the totality of their experiences with the Manager and OFI as trustees of the Fund and other funds advised by the Manager or OFI. The Board considered information regarding the quality of services provided by affiliates of the Manager, which the Board members have become knowledgeable about through their experiences with the Manager or OFI and in connection with the renewal of the Fund’s service agreements. The Board concluded, in light of the Manager’s and OFI’s experience, reputation, personnel, operations and resources that the Fund benefits from the services provided under the Agreement.

Investment Performance of the Manager and the Fund. Throughout the year, the Manager provided information on the investment performance of the Fund and the Manager, including comparative performance information. The Board also reviewed information, prepared by the Manager and the independent consultant, comparing the Fund’s historical performance to relevant market indices and to the performance of other retail energy limited partnership funds. The Board noted that the Fund outperformed its category median for the one- and three-year periods, and that it performed in line with its category median for the five-year period.

Fees and Expenses of the Fund. The Board reviewed the fees paid to the Manager and the other expenses borne by the Fund. The Board also considered the comparability of the fees charged and the services provided to the Fund to the fees and services for other clients or accounts advised by the Adviser. The independent consultant provided comparative data in regard to the fees and expenses of the Fund and other retail energy limited partnership funds with comparable asset levels and distribution features. The Board noted that the Fund’s contractual management fee was equal to its category median and one basis point higher than its peer group median and that the Fund’s total expenses, net of waivers, were one basis point lower than its category median and equal to its peer group median. The Board considered that the Fund’s contractual management fee includes both the advisory fee and the administrative fee, which contribute to the Fund’s costs and noted that the administrative

OPPENHEIMER STEELPATH MLP ALPHA FUND 41

BOARD APPROVAL OF THE FUND’S INVESTMENT
ADVISORY AGREEMENT Unaudited / (Continued)

fee reflects the complex tax work associated with the Fund’s MLP investments. The Board considered that the Manager has contractually agreed to waive fees and/or reimburse the Fund so that total expenses, as a percentage of average daily net assets, will not exceed the following annual rates: 1.50% for Class A shares, 2.25% for Class C shares and 1.25% for Class Y shares. The fee limitation may not be amended or withdrawn prior to its expiration on March 30, 2017, unless approved by the Board.

Economies of Scale and Profits Realized by the Manager. The Board considered information regarding the Manager’s costs in serving as the Fund’s investment adviser, including the costs associated with the personnel and systems necessary to manage the Fund, and information regarding the Manager’s profitability from its relationship with the Fund. The Board also considered that the Manager must be able to pay and retain experienced professional personnel at competitive rates to provide quality services to the Fund. The Board reviewed whether the Manager may 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 Manager. In addition to considering the profits realized by the Manager, the Board considered information that was provided regarding the direct and indirect benefits the Manager receives as a result of its relationship with the Fund, including compensation paid to the Manager’s affiliates and research provided to the Manager in connection with permissible brokerage arrangements (soft dollar arrangements).

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 Manager within the meaning and intent of the Securities and Exchange Commission Rules.

Based on its review of the information it received and its evaluations described above, the Board, including a majority of the independent Trustees, decided to continue the Agreement through August 31, 2017. 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 Agreement, including the management fees, in light of all the surrounding circumstances.

DISTRIBUTION SOURCES Unaudited

For any distribution that took place over the last six months of the Fund’s reporting period, the table below details, on a per-share basis, the percentage of the Fund’s total distribution payment amount that was derived from the following sources: net income, net profit from the sale of securities, and other capital sources. This information is based upon income and capital gains using generally accepted accounting principles as of the date of each distribution. For certain securities, such as Master Limited Partnerships (“MLPs”), the percentages attributed to each category are estimated using historical information because the character of the amounts received from the MLPs in which the Fund invests is unknown until after the end of the calendar year. Because the Fund is actively managed, the relative amount of the Fund’s total distributions derived from various sources over the calendar year may change. Please note that this information should not be used for tax reporting purposes as the tax character of distributable income may differ from the amounts used for this notification. You will receive IRS tax forms in the first quarter of each calendar year detailing the actual amount of the taxable and non-taxable portion of distributions paid to you during the tax year.

For the most current information, please go to oppenheimerfunds.com. Select your Fund, then the ’Detailed’ tab; where ‘Dividends’ are shown, the Fund’s latest pay date will be followed by the sources of any distribution, updated daily.

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.

Fund Performance Discussion

The Fund’s Class A shares (without sales charge) produced a total return of 7.29% during the reporting period. In comparison, master limited partnerships (“MLPs”), as measured by the Alerian MLP Index (AMZ), provided a total return gain of 9.28%. Please note that the returns for the Alerian MLP Index are calculated pre-tax, while the Fund’s returns are calculated post corporate tax. During the same period, the S&P 500 Index produced a total return gain of 8.06%.

Over the twelve-month reporting period ended November 30, 2016, the midstream sector outperformed the broader markets as the lows of the current energy cycle appear to have been reached and the beginnings of a recovery appear to be unfolding. Late in the period, the Organization of Petroleum Exporting Countries (“OPEC”) provided a potential acceleration to the rebalancing of crude oil supply and demand by announcing formal plans to reduce its production to 32.5 million barrels of oil per day (MMbbls/d) by January 2017. Agreements with non-OPEC countries to provide additional support via another 0.6 MMbbls/d of supply reductions were also announced, most notably with Russia electing to reduce production by 0.3 MMbbls/d. The larger than expected supply reduction sent oil prices sharply higher and many energy equities even more so. This reduced supply from OPEC members will pull the consensus estimates for the 2017 oil market balance back firmly into an undersupplied position, thereby beginning the process of working down

OPPENHEIMER STEELPATH MLP INCOME FUND 3

global inventories. And, importantly for U.S. midstream investors, the OPEC cut helps reduce the market forces that were driving near-term U.S. production, and thus midstream throughput, lower. Further, we continue to believe that this energy down cycle has shifted the call on U.S.-sourced volumes higher over the medium-term. This improving fundamental commodity picture, combined with midstream valuations that remain below long-term averages, makes a compelling case for midstream investment.

Over the reporting period, we estimate approximately $26 billion of new equity supply entered the market through either secondary offerings, initial public offerings, or “at-the-market” programs in which primary units trade into the market anonymously throughout the normal trading day. This pace of equity issuance represents an increase from approximately $20 billion that was raised over the twelve month reporting period ended November 30, 2015. MLPs also raised approximately $23 billion of debt capital during the period. Most MLPs pay out the majority of excess cash flow as distributions to investors, and therefore must raise external capital to fund growth projects and to fund acquisitions.

MACRO REVIEW

West Texas Intermediate (WTI) crude oil prices ended the reporting period at $49.44 per barrel, up 19% from the prior year. Global crude prices, as measured by Brent crude oil, traded 13% higher over the reporting period. The crude oil price improvement appears linked to the continued moderation in U.S. crude production, healthy demand growth, and the aforementioned OPEC deal to reduce supply. Brent exited the period at a $1 per barrel premium to WTI, which is near the historic norm. However, this reversion represents a departure from the $8 to $9 per barrel Brent premium that has generally existed since 2009.

Henry Hub natural gas spot prices exited the period at $3.30 per million British thermal units (“mmbtu”), up 58% over the reporting period. Natural gas pricing has benefited from a long awaited realignment of supply-demand in which natural gas usage as a heating and electric generation fuel has increased as gas production volume growth has declined, and as increased exports have become a reality via both liquefied natural gas and new pipelines to Mexico.

Mont Belvieu NGL prices ended the reporting period at $23.92 per barrel, a 26% increase over the reporting period. All of the NGL purity products ended the period higher than the same time in the prior year. Frac spreads, a measure of natural gas processing economics, ended the period at $0.28 per gallon, up 4% over the reporting period. Generally, the greater the frac spread, the greater the incentive for producers to seek natural gas processing capacity.

The yield curve modestly flattened over the reporting period as short rates rose more than the yields on longer-dated maturities. The ten-year Treasury yield rose 18 basis points to end the period at 2.38%.

4 OPPENHEIMER STEELPATH MLP INCOME FUND

The MLP yield spread at period-end, as measured by the AMZ and the 10-year Treasury bond, narrowed by 115 basis points to 5.05%.

Over the reporting period, real estate investment trusts (“REITs”) and utilities, two competing yield-oriented equity asset classes, posted total returns of 5.65% (as measured by the Dow Jones Equity REIT Total Return Index) and 16.31% (as measured by the Dow Jones Utility Average Index), respectively, as compared to the AMZ’s 9.28% total return. Price to forward distributable cash flow (DCF), a commonly watched ratio within the MLP sector, increased over the period but remains below the ten-year average.

SUBSECTOR REVIEW

Performance among subsectors in the midstream, or energy infrastructure, MLP asset class varied for the reporting period. On average, the gathering and processing subsector provided the best performance over the period, buoyed by improving commodity prices supporting improved volumetric projections. The natural gas pipeline group followed as investors continued to express preference for long-haul natural gas pipelines, particularly those backed by utility demand pull.

The marine subsector experienced the weakest performance over the reporting period as several entities substantially reduced cash distributions to investors. The propane subsector also lagged over the reporting period as market participants appeared to rotate out of the subsector in favor of more traditional midstream names and as rising propane prices could result in some margin pressure in future periods.

FUND REVIEW

Key contributors to the Fund were NuStar Energy LP (NS) and ONEOK Partners, LP (OKS).

NuStar units contributed positively to the portfolio during the period as the partnership continued to deliver robust financial results supported by a strong portfolio of contractual agreements. Investor comfort with the partnership’s cash flow generation ability and attractive yield likely contributed to the outperformance during the period.

OKS units performed well over the period, benefiting from processing margin improvements and after aggressively converting much of its commodity-exposed contracts to a fee-based business. Sentiment also improved among market participants regarding forward-looking ethane recoveries.

Key detractors from the Fund were Teekay LNG Partners LP (TGP) and Sunoco LP (SUN).

TGP units experienced declines early in the reporting period after announcing an unexpected distribution reduction. TGP’s decision to change its dividend payout philosophy was unexpected as the company’s operating performance has continued to be very resilient. TGP’s heavily contracted fleet of LNG

OPPENHEIMER STEELPATH MLP INCOME FUND 5

carriers generate cash flows that are largely insulated from near-term movements in commodity prices.

SUN units underperformed over the period as investor concern increased over the partnership’s elevated leverage metrics following a series of significant acquisitions. We believe the partnership’s diverse geographic footprint and focus on the resilient fuel distribution business should provide the potential for steady long-term operational performance.

Please note that significant decreases in cash distributions from the Fund’s MLP investments and/or significant declines in the fair value of its investments may impact the Fund’s assessment regarding the recoverability of certain deferred tax assets, which may result in the recording of a valuation allowance. If a valuation allowance is established, this could have a material impact on the Fund’s net asset value and results of operations for the period. The Fund had a valuation allowance in place for a portion of the reporting period, but did not have one in place at period end. See Note 2 of the Notes to Financial Statements for more information.

OUTLOOK

We believe we have seen the worst of this energy market down cycle. The rate of midstream growth will likely moderate from peak levels, but average distributions are still likely to grow. Midstream operators may also stand to benefit as they make more efficient use of their existing assets. We believe current market valuations underestimate the potential for renewed business growth going forward and remain optimistic on the sector’s prospects. For this reason, we believe MLPs continue to offer attractive total return potential based on the potential for price appreciation and stable or growing distribution streams.

The Fund’s performance is compared to the performance of the S&P 500 Index and the Alerian MLP Index. The S&P 500 Index is a broad-based measure of domestic stock performance. The Alerian MLP Index is a composite of the 50 most prominent Master Limited Partnerships that provides investors with an unbiased, comprehensive benchmark for this emerging asset class. The Alerian MLP Index, which is calculated using a float-adjusted, capitalization-weighted methodology, is disseminated real-time on a total-return basis. The indices are 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 indices. 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 Fund’s investment strategy and focus can change over time. The mention of specific fund holdings does not constitute a recommendation by OppenheimerFunds, Inc. or its affiliates.

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, 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 November 30, 2016.

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 November 30, 2016” 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). 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	1,005.42	19.63
CLASS Y	1,000.00	1,004.94	20.11

Expenses are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 183/366 (to reflect the one-half year period). Those annualized expense ratios, excluding indirect expenses from affiliated funds, based on the 6-month period ended November 30, 2016 are as follows:

Class	Expense Ratios
CLASS A	4.26%
CLASS C	5.01
CLASS I	3.92
CLASS Y	4.01

The expense ratios for Class A, C, and Y reflect 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, if applicable.

OPPENHEIMER STEELPATH MLP INCOME FUND 23

NOTES TO FINANCIAL STATEMENTS

1. Organization

Oppenheimer SteelPath MLP Income Fund (the “Fund”), a separate series of Oppenheimer SteelPath MLP Funds Trust, is a non-diversified open-end management investment company registered under the Investment Company Act of 1940, as amended. The Fund’s investment objective is to seek total return. The Fund’s investment adviser is OFI SteelPath, Inc. (the “Adviser” or “Manager”), a wholly-owned subsidiary of OppenheimerFunds, Inc. (“OFI” or “Oppenheimer”).

The Fund offers Class A, Class C, Class I, and Class Y shares. Effective as of January 25, 2016, the Fund is open to new investors, subject to the terms described in the Prospectus dated March 28, 2016, as supplemented. Effective June 28, 2013, Class I shares were renamed Class Y shares. Class A shares are sold at their offering price, which is normally net asset value plus a front-end sales charge. Effective June 28, 2013 although there is no initial sales charge on Class A purchases totaling $1 million or more, those Class A shares may be subject to a 1.00% contingent deferred sales charge (“CDSC”) if shares are redeemed within an 18-month “holding period” measured from the date of purchase. Class C shares are sold without a front-end sales charge but may be subject to a CDSC of 1.00% of the redemption proceeds if Class C shares are redeemed within one year of purchase. Class I shares are only available to eligible institutional investors. Class I shares are sold at net asset value per share without a sales charge or CDSC. An institutional investor that buys Class I shares for its customers’ accounts may impose charges on those accounts. Class Y shares are sold at net asset value per share without a sales charge directly to institutional investors that have special agreements with OppenheimerFunds Distributor, Inc. (the “Distributor”) for that purpose. They may include insurance companies, registered investment companies, employee benefit plans and section 529 plans, among others. An institutional investor that buys Class Y shares for its customers’ accounts may impose charges on those accounts. All classes of shares have identical rights and voting privileges with respect to the Fund in general and exclusive voting rights on matters that affect that class alone. Earnings, net assets and net asset value per share may differ due to each class having its own expenses, such as transfer and shareholder servicing agent fees and shareholder communications, directly attributable to that class. Class A and C shares have separate distribution and/or service plans under which they pay fees. Class I and Y shares do not pay such fees.

The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification Topic 946 Financial Services- Investment Companies.

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”).

NOTES TO FINANCIAL STATEMENTS (Continued)

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. generally accepted accounting principles, are recorded on the ex-dividend date. Dividends, if any, are declared and distributed monthly for the Fund. The estimated characterization of the distributions paid will be either a qualified dividend or distribution (return of capital). This estimate is based on the Fund’s operating results during the period. It is anticipated that a significant portion of the distributions will be comprised of return of capital as a result of the tax character of cash distributions made by the Fund’s investments. The actual characterization of the distributions made during the period will not be determined until after the end of the fiscal year. The Fund will inform shareholders of the final tax character of the distributions on IRS Form 1099 DIV in February 2017. For the year ended November 30, 2016, the Fund distributions are expected to be comprised of 100% return of capital.

Return of Capital Estimates. Distributions received from the Fund’s investments in MLPs generally are comprised of income and return of capital. The Fund records investment income and return of capital based on estimates made at the time such distributions are received. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on information received from MLPs after their tax reporting periods are concluded. For the year ended November 30, 2016, the Fund estimated that 100% of the MLP distributions received would be treated as 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 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, if applicable, are amortized or accreted daily.

Custodian Fees. “Custody fees” 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

OPPENHEIMER STEELPATH MLP INCOME FUND 25

2. Significant Accounting Policies (Continued)

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 using 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 Income Taxes. The Fund does not intend to qualify as a regulated investment company pursuant to Subchapter M of the Internal Revenue Code, but will rather be taxed as a corporation. As a corporation, the Fund is obligated to pay federal, state and local income tax on taxable income. Currently, the maximum marginal regular federal income tax rate for a corporation is 35 percent. Upon enactment, a change in the federal income tax rate could have a material impact to the Fund. The Fund may be subject to a 20 percent alternative minimum tax on its federal alternative minimum taxable income to the extent that its alternative minimum tax exceeds its regular federal income tax. The Fund is currently using an estimated rate of 1.5 percent for state and local tax, net of federal tax expense.

The Fund’s income tax provision consists of the following as of November 30, 2016:

Current tax expense/(benefit)
Federal	$	—
State		—
Total current tax expense	$	—
Deferred tax expense/(benefit)
Federal	$	59,059,269
State		4,993,667
Total deferred tax expense	$	64,052,936

2. Significant Accounting Policies (Continued)

The reconciliation between the federal statutory income tax rate of 35% and the effective tax rate on net investment income (loss) and realized and unrealized gain (loss) follows:

	Amount			Rate
Application of federal statutory income tax rate	$	109,664,735			35.00	%
State income taxes net of federal benefit		4,699,917			1.50	%
Effect of state tax rate change		2,462,555			0.79	%
Effect of permanent differences		(273,458	)		(0.09	%)
Change in valuation allowance		(52,500,813	)		(16.76	%)
Total income tax expense (benefit)	$	64,052,936			20.44	%

For the year ended November 30, 2016 the Fund’s effective tax rate of 20.44% (net expense) differed from the combined federal and state statutory tax rate of 36.5% (net expense) mainly due to the change in valuation allowance primarily as a result of the change in unrealized appreciation.

The Fund intends to invest its assets primarily in MLPs, which generally are treated as partnerships for federal income tax purposes. As a limited partner in the MLPs, the Fund reports its allocable share of the MLP’s taxable income in computing its own taxable income. The Fund’s tax expense or benefit will be included in the Statement of Operations based on the component of income or gains (losses) to which such expense or benefit relates. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Such temporary differences are principally: (i) taxes on unrealized gains/(losses), which are attributable to the temporary difference between fair market value and tax basis, (ii) the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes and (iii) the net tax benefit of accumulated net operating losses and capital loss carryforwards. Deferred tax assets and liabilities are measured using effective tax rates expected to apply to taxable income in the years such temporary differences are realized or otherwise settled. To the extent the Fund has a deferred tax asset, consideration is given to whether or not a valuation allowance is required. A valuation allowance is required if, based on the evaluation criterion provided by ASC 740, Income Taxes (ASC 740), it is more-likely-than-not some portion or all of the deferred tax asset will not be realized. Among the factors considered in assessing the Fund’s valuation allowance are: the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of the statutory carryforward periods, significant redemptions, and the associated risks that operating and capital loss carryforwards may expire unused.

OPPENHEIMER STEELPATH MLP INCOME FUND 27

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

At November 30, 2016, the Fund determined a valuation allowance was not required. In evaluating a valuation allowance on a portion of the deferred tax asset, significant consideration was given to the current and expected level of MLP distributions, unrealized gains and losses on MLP investments and the expiration dates for net operating losses and capital loss carryovers. Market cycles, the severity and duration of historical deferred tax assets and the impact of current and future redemptions were also considered. The Fund intends to assess whether a valuation allowance is required to offset some or all of any deferred tax asset balance in connection with the calculation of the Fund’s daily NAV; however, to the extent the final valuation allowance differs from the estimates of the Fund used in calculating the Fund’s daily NAV, the application of such final valuation allowance in these Financial Statements could have a material impact on the Fund’s NAV. Through the consideration of these factors, the Fund has determined that it is more likely than not the deferred tax asset, net of the valuation allowance, if required, will be realized.

Unexpected significant decreases in cash distributions from the Fund’s MLP investments, significant declines in the fair value of its investments, significant redemptions, or increased risk of expiring net operating losses or capital loss carryovers may change the Fund’s assessment regarding the recoverability of its deferred tax assets and may result in a change to the valuation allowance. Modifications of the valuation allowance could have a material impact on the Fund’s net asset value.

Components of the Fund’s deferred tax assets and liabilities as of November 30, 2016 are as follows:

Deferred tax assets:
Net operating loss carryforward (tax basis)	$	204,091,121
Capital loss carryforward (tax basis)		192,089,996
Book to tax differences - Income recognized from MLPs		5,115,697
Total deferred tax asset		401,296,814
Deferred tax liabilities:
Net unrealized gains on investment securities (tax basis)	$	(214,205,670	)
Total deferred tax liability		(214,205,670	)
Total net deferred tax asset/(liability)	$	187,091,144

The Fund may rely, to some extent, on information provided by the MLPs, which may not necessarily be timely, to estimate taxable income allocable to MLP units held in its portfolio, and to estimate its associated deferred tax liability or asset. Such estimates are made in good faith. From time to time, as new information becomes available, the Fund will modify its estimates or assumptions regarding its tax liability or asset.

2. Significant Accounting Policies (Continued)

The Fund’s policy is to classify interest and penalties associated with underpayment of federal and state income taxes, if any, as income tax expense on its Statement of Operations. As of November 30, 2016, the Fund does not have any interest or penalties associated with the underpayment of any income taxes.

The Fund files income tax returns in the U.S. federal jurisdiction and various states. The Fund has reviewed all major jurisdictions and concluded that there is no significant impact on the Fund’s net assets and no tax liability resulting from unrecognized tax benefits relating to uncertain tax positions expected to be taken on its tax returns. Furthermore, management of the Fund is not aware of any uncertain tax positions for which it is reasonably possible that the total amount of unrecognized tax benefit will significantly change in the next 12 months.

At November 30, 2016, the Fund had net operating loss carryforwards for federal income tax purposes, which may be carried forward for 20 years, as follows:

Expiration Date
11/30/2030	$	3,877

2. Significant Accounting Policies (Continued)

The difference between cost amounts for financial statement and federal income tax purposes is due primarily to timing differences in recognizing certain gains and losses in security transactions.

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.

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 of Trustees (the “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 Adviser. The Adviser 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:

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. If the official closing price or last sales 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,

30 OPPENHEIMER STEELPATH MLP INCOME FUND

NOTES TO FINANCIAL STATEMENTS (Continued)

3. Securities Valuation (Continued)

the security is valued by using one of the following methodologies (listed in order of priority): (1) 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 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.

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 Adviser, 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 Adviser’s Valuation Committee. The Valuation Committee considers all relevant facts that are reasonably available, through either public information or

OPPENHEIMER STEELPATH MLP INCOME FUND 31

NOTES TO FINANCIAL STATEMENTS (Continued)

3. Securities Valuation (Continued)

information available to the Adviser, when determining the fair value of a security. Fair value determinations by the Adviser 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 Adviser, or its third party service provider who is subject to oversight by the Adviser, 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.)

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

The following table summarizes the valuation techniques and significant unobservable inputs used in determining fair value measurements for those investments classified as Level 3 as of November 30, 2016:

Type of Investment	Values as of November 30, 2016		Valuation Technique	Unobservable Input	Range of Unobservable Inputs			Unobservable Input Used
Preferred Master Limited Partnership Shares	$	14,881,890	Discounted Cash Flow Model	Estimated yield		8.1% - 13.2	%		11.4	%(a)

Total	$	44,926,890

(a) The Fund fair values certain preferred shares using a discounted cash flow model which values the shares at the expected value of common units to be received in PIK conversion based on: the current price of the common shares (observable), the 20-day volume weighted average price (VWAP) of the common shares (observable), the 3-day volume weighted average price of the common shares (observable), and a discount rate, which is derived from the estimated yield and an illiquidity discount. Such security’s fair valuation could decrease (increase) significantly based on an increase (decrease) in the illiquidity discount. Such security’s fair valuation could increase (decrease) significantly based on an increase (decrease) in expected yields.

(b) The Fund fair values certain preferred shares using a discounted cash flow model, which incorporates an illiquidity discount and the expected yield based on the average yield on comparable companies’ equity. Such security’s fair valuation could decrease (increase) significantly based on an increase (decrease) in the illiquidity discount. Such security’s fair valuation could decrease (increase) significantly based on an increase (decrease) in expected yields.

There have been no transfers between pricing levels for the Fund. It is the Fund’s policy to recognize transfers at the beginning of the reporting period.

4. Investments and Risks

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

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

Master Limited Partnerships (“MLPs”). Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowings for investment purposes) in the equity securities of MLPs.

MLPs issue common units that represent an equity ownership interest in a partnership and provide limited voting rights. MLP common units are registered with the Securities and Exchange Commission (“SEC”), and are freely tradable on securities exchanges such as the NYSE and the NASDAQ Stock Market (“NASDAQ”), or in the over-the-counter (“OTC”) market. An MLP consists of one or more general partners, who conduct the business, and one or more limited partners, who contribute capital. MLP common unit holders have a limited role in the partnership’s operations and management. The Fund, as a limited partner, normally would not be liable for the debts of the MLP beyond the amounts the Fund has contributed, but would not be shielded to the same extent that a shareholder of a corporation would be. In certain circumstances creditors of an MLP would have the right to seek return of capital distributed to a limited partner. This right of an MLP’s creditors would continue after the Fund sold its investment in the MLP.

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

Concentration Risk. Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowing for investment purposes) in the equity securities of MLPs. MLPs are subject to certain risks, such as supply and demand risk, depletion and exploration risk, commodity pricing risk, acquisition risk, and the risk associated with the hazards inherent in midstream energy industry activities. A substantial portion of the cash

OPPENHEIMER STEELPATH MLP INCOME FUND 35

NOTES TO FINANCIAL STATEMENTS (Continued)

4. Investments and Risks (Continued)

flow received by the Fund is derived from investment in equity securities of MLPs. The amount of cash that a MLP has available for distributions, and the tax character of such distributions, are dependent upon the amount of cash generated by the MLP’s operations.

5. Market Risk Factors

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

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

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

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

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

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

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

	Purchases		Sales
Investment securities	$	1,288,005,086	$	650,181,461

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:

Net Assets up to $3 Billion	Net Assets Greater than $3 Billion and up to $5 Billion	Net Assets in Excess of $5 Billion
0.95%	0.93%	0.90%

The Fund’s effective management fee for the year ended November 30, 2016 was 0.95% of average annual net assets before any applicable waivers.

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 with respect to these services are detailed in the Statement of Operations.

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 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

38 OPPENHEIMER STEELPATH MLP INCOME FUND

NOTES TO FINANCIAL STATEMENTS (Continued)

8. Fees and Other Transactions with Affiliates (Continued)

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

Distribution and Service Plans for Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for distributing those share classes, maintaining accounts and providing shareholder services. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class C shares daily net assets. The Fund also pays a service fee under the Plans at an annual rate of 0.25% of daily net assets.

The Plan and Plans continue in effect from year to year only if the Fund’s Board votes annually to approve their continuance at an in person meeting called for that purpose. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations.

8. Fees and Other Transactions with Affiliates (Continued)

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
November 30, 2016	$	2,371,164	$	6,858	$	83,096

Waivers and Reimbursements of Expenses. The Manager has contractually agreed to limit fees and/or reimburse expenses of the Fund to the extent that the Fund’s total annual fund operating expenses (exclusive of interest, taxes, such as deferred tax expenses, brokerage commissions, acquired fund fees and expenses, dividend costs related to short sales, and litigation expense, if any) exceed 1.35% for Class A shares, 2.10% for Class C shares, and 1.10% for Class Y shares.

The Fund’s total annual operating expenses after fee waiver and/or expense reimbursement (“Net Expenses”) will be higher than these amounts to the extent that the Fund incurs expenses excluded from the expense cap. Because the Fund’s deferred income tax expense/(benefit) and borrowing fees are excluded from the expense cap, the Fund’s Net Expenses for each class of shares is increased/(decreased) by the amount of this expense. During the year ended November 30, 2016, the Manager reimbursed $1,608,024, $1,194,846, and $790,237 for Class A, Class C, and Class Y, respectively. This undertaking may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein, unless approved by the Fund’s Board of Trustees.

The Manager can be reimbursed by the Fund within three years after the date the fee limitation and/or expense reimbursement has been made by the Manager, provided that such repayment does not cause the expenses of any class of the Fund to exceed the foregoing limits.

The following table represents amounts eligible for recovery at November 30, 2016:

Eligible Expense Recoupment Expiring:
November 30, 2017	$	4,687,900

9. Borrowing Agreement

The Fund, along with Oppenheimer SteelPath MLP Alpha Plus Fund, Oppenheimer SteelPath MLP Alpha Fund, and Oppenheimer SteelPath MLP Select 40 Fund (collectively, the “Trust”), is a borrower in a $700 million revolving credit agreement (the “Loan Agreement”) with a major lending institution (the “Lender”). The Fund is permitted to borrow up to the lesser of one-third of the Fund’s total assets, or the maximum amount permitted pursuant to the Fund’s investment limitations. The borrowing, if any, is fully collateralized throughout the term of the borrowing with securities or other assets of the Fund. The Fund is not liable for borrowings of other Funds in the Trust. Securities that have been pledged as collateral for the borrowing are indicated in the Statement of Investments.

Borrowings under the Loan Agreement are charged interest at a calculated rate computed by the Lender based on the one month LIBOR rate plus 0.65% per annum. An unused commitment fee at the rate of 0.125% per annum is charged for any undrawn portion of the credit facility, and each member of the Trust will pay its pro rata share of this fee. A facility fee of 0.20% was charged on the commitment amount, and each party of the Trust paid its pro rata share of this fee. The borrowing is due November 17, 2017, unless another date is mutually agreed upon by the parties of the Loan Agreement. For the year ended November 30, 2016, the Fund paid $659,039 in borrowing fees. The Fund did not utilize the facility during the year ended November 30, 2016.

10. Pending Litigation

In 2009, several putative class action lawsuits were filed and later consolidated before the U.S. District Court for the District of Colorado in connection with the investment performance of Oppenheimer Rochester California Municipal Fund (the “California Fund”), a fund advised by OppenheimerFunds, Inc. (“OFI”) – the parent company of the manager and distributed by OppenheimerFunds Distributor, Inc. (“OFDI”). The plaintiffs asserted claims against OFI, OFDI and certain present and former trustees and officers of the California Fund under the federal securities laws, alleging, among other things, that the disclosure documents of the California Fund contained misrepresentations and omissions and the investment policies of the California Fund were not followed. An amended complaint and a motion to dismiss were filed, and in 2011, the court issued an order which granted in part and denied in part the

10. Pending Litigation (Continued)

defendants’ motion to dismiss. In October 2015, following a successful appeal by defendants and a subsequent hearing, the court granted plaintiffs’ motion for class certification and appointed class representatives and class counsel.

OFI and OFDI believe the suit is without merit; that it is premature to render any opinion as to the likelihood of an outcome unfavorable to them in the Suit; and that no estimate can yet be made as to the amount or range of any potential loss. Furthermore, OFI believes that the suit should not impair the ability of OFI or OFDI to perform their respective duties to the Fund and that the outcome of the suit should not have any material effect on the operations of any of the Oppenheimer funds.

REPORT OF INDEPENDENT REGISTERED PUBLIC
ACCOUNTING FIRM

To the Shareholders of Oppenheimer SteelPath MLP Income Fund and
Board of Trustees of Oppenheimer SteelPath MLP Funds Trust

We have audited the accompanying statement of assets and liabilities, including the statement of investments, of Oppenheimer SteelPath MLP Income Fund (the “Fund”), a series of Oppenheimer SteelPath MLP Funds Trust, as of November 30, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of November 30, 2016, by correspondence with the custodian and brokers or by other auditing procedures as appropriate in the circumstances. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Oppenheimer SteelPath MLP Income Fund as of November 30, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

The Fund has entered into an investment advisory agreement (the “Agreement”) with OFI SteelPath, Inc. (“OFI SteelPath” or the “Manager”). Each year, the Board of Trustees (the “Board”), including a majority of the independent Trustees, is required to determine whether to approve the terms of the Agreement and the renewal thereof. The Investment Company Act of 1940, as amended, requires that the Board request and evaluate, and that the Manager provide, such information as may be reasonably necessary to evaluate the terms of the Agreement. The Board employs an independent consultant to prepare a report that provides information, including comparative information that the Board requests for that purpose. In addition to in-person meetings focused on this evaluation, the Board receives information throughout the year regarding Fund services, fees, expenses and performance.

The Manager and the independent consultant provided information to the Board on the following factors: (i) the nature, quality and extent of the Manager’s services, (ii) the comparative investment performance of the Fund and the Manager, (iii) the fees and expenses of the Fund, including comparative fee and expense information, (iv) the profitability of the Manager and its 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 Manager from its relationship with the Fund. The Board was aware that there are alternatives to retaining the Manager.

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 Manager’s key personnel who provide such services. The Manager’s duties include providing the Fund with the services of the portfolio managers and investment team, who provide research, analysis and other advisory services in regard to the Fund’s investments; and securities trading services. The Manager is responsible for 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 Manager is also responsible for providing certain administrative services to the Fund. Those services, some of which are performed by affiliates of the Manager, 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 U.S. Securities and Exchange Commission; preparing periodic reports regarding the operations of the Fund for its shareholders; preparing proxy materials for shareholder meetings; and preparing the registration statements required by federal and state securities laws for the sale of the Fund’s shares. The Manager also provides the Fund with office space, facilities and equipment.

The Board also considered the quality of the services provided and the quality of the Manager’s resources that are available to the Fund. In evaluating the Manager, the Board considered the history, reputation, qualification and background of the Manager, including its corporate parent, OppenheimerFunds, Inc. (“OFI”) and corporate affiliate, OFI Global Asset Management, Inc. (“OFI Global” and OFI and OFI Global are collectively referred to hereinafter as “OFI”), and the fact that OFI has over 50 years of experience as an investment adviser and that its assets under management rank it among the top mutual fund managers in the United States. The Board evaluated the Manager’s and OFI’s advisory, administrative, accounting, legal, compliance and risk management services, and information the Board has received regarding the experience and professional qualifications of the Manager’s and OFI’s 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 Stuart Cartner and Brian Watson, the portfolio managers for the Fund, and the Manager’s investment team and analysts. The Board members also considered the totality of their experiences with the Manager and OFI as trustees of the Fund and other funds advised by the Manager or OFI. The Board considered information regarding the quality of services provided by affiliates of the Manager, which the Board members have become knowledgeable about through their experiences with the Manager or OFI and in connection with the renewal of the Fund’s service agreements. The Board concluded, in light of the Manager’s and OFI’s experience, reputation, personnel, operations and resources that the Fund benefits from the services provided under the Agreement.

Investment Performance of the Manager and the Fund. Throughout the year, the Manager provided information on the investment performance of the Fund and the Manager, including comparative performance information. The Board also reviewed information, prepared by the Manager and by the independent consultant, comparing the Fund’s historical performance to relevant market indices and to the performance of other retail energy limited partnership funds. The Board noted that the Fund outperformed its category median for the one- and three-year periods and underperformed its category median for the five-year period.

Fees and Expenses of the Fund. The Board reviewed the fees paid to the Manager and the other expenses borne by the Fund. The Board also considered the comparability of the fees charged and the services provided to the Fund to the fees and services for other clients or accounts advised by the Adviser. The independent consultant provided comparative data in regard to the fees and expenses of the Fund and other retail energy limited partnership funds with comparable asset levels and distribution features. The Board noted that the Fund’s contractual management fee and total expenses were lower than their respective peer group medians and category medians. The Board considered that the Manager has contractually agreed to waive fees and/or reimburse the Fund so that total expenses, as a percentage of average daily net assets, will not exceed the following annual rates: 1.35% for Class A shares, 2.10% for Class C shares and 1.10% for Class Y shares. The fee limitation may not be amended or withdrawn prior to its expiration on March 30, 2017, unless approved by the Board.

Economies of Scale and Profits Realized by the Manager. The Board considered information regarding the Manager’s costs in serving as the Fund’s investment adviser, including the costs associated with the personnel and systems necessary to manage the Fund, and information regarding the Manager’s profitability from its relationship with the Fund. The Board also considered that the Manager must be able to pay and retain experienced professional personnel at competitive rates to provide quality services to the Fund. The Board reviewed whether the Manager may 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 Manager. In addition to considering the profits realized by the Manager, the Board considered information that was provided regarding the direct and indirect benefits the Manager receives as a result of its relationship with the Fund, including compensation paid to the Manager’s affiliates and research provided to the Manager in connection with permissible brokerage arrangements (soft dollar arrangements).

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 Manager within the meaning and intent of the Securities and Exchange Commission Rules.

Based on its review of the information it received and its evaluations described above, the Board, including a majority of the independent Trustees, decided to continue the Agreement through August 31, 2017. 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 Agreement, including the management fees, in light of all the surrounding circumstances.

DISTRIBUTION SOURCES Unaudited

For any distribution that took place over the last six months of the Fund’s reporting period, the table below details, on a per-share basis, the percentage of the Fund’s total distribution payment amount that was derived from the following sources: net income, net profit from the sale of securities, and other capital sources. This information is based upon income and capital gains using generally accepted accounting principles as of the date of each distribution. For certain securities, such as Master Limited Partnerships (“MLPs”), the percentages attributed to each category are estimated using historical information because the character of the amounts received from the MLPs in which the Fund invests is unknown until after the end of the calendar year. Because the Fund is actively managed, the relative amount of the Fund’s total distributions derived from various sources over the calendar year may change. Please note that this information should not be used for tax reporting purposes as the tax character of distributable income may differ from the amounts used for this notification. You will receive IRS tax forms in the first quarter of each calendar year detailing the actual amount of the taxable and non-taxable portion of distributions paid to you during the tax year.

For the most current information, please go to oppenheimerfunds.com. Select your Fund, then the ’Detailed’ tab; where ‘Dividends’ are shown, the Fund’s latest pay date will be followed by the sources of any distribution, updated daily.

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.

Fund Performance Discussion

The Fund’s Class A shares (without sales charge) produced a total return of 6.66% during the reporting period. In comparison, master limited partnerships (“MLPs”), as measured by the Alerian MLP Index (AMZ), provided a total return gain of 9.28%. Please note that the returns for the Alerian MLP Index are calculated pre-tax, while the Fund’s returns are calculated post corporate tax. During the same period, the S&P 500 Index produced a total return gain of 8.06%.

Over the twelve-month reporting period ended November 30, 2016, the midstream sector outperformed the broader markets as the lows of the current energy cycle appear to have been reached and the beginnings of a recovery appear to be unfolding. Late in the period, the Organization of Petroleum Exporting Countries (“OPEC”) provided a potential acceleration to the rebalancing of crude oil supply and demand by announcing formal plans to reduce its production to 32.5 million barrels of oil per day (MMbbls/d) by January 2017. Agreements with non-OPEC countries to provide additional support via another 0.6 MMbbls/d of supply reductions were also announced, most notably with Russia electing to reduce production by 0.3 MMbbls/d. The larger than expected supply reduction sent oil prices sharply higher and many energy equities even more so. This reduced supply from OPEC members will pull the consensus estimates for the 2017 oil market balance back firmly

OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND 3

into an undersupplied position, thereby beginning the process of working down global inventories. And, importantly for U.S. midstream investors, the OPEC cut helps reduce the market forces that were driving near-term U.S. production, and thus midstream throughput, lower. Further, we continue to believe that this energy down cycle has shifted the call on U.S.-sourced volumes higher over the medium-term. This improving fundamental commodity picture, combined with midstream valuations that remain below long-term averages, makes a compelling case for midstream investment.

Over the reporting period, we estimate approximately $26 billion of new equity supply entered the market through either secondary offerings, initial public offerings, or “at-the-market” programs in which primary units trade into the market anonymously throughout the normal trading day. This pace of equity issuance represents an increase from approximately $20 billion that was raised over the twelve month reporting period ended November 30, 2015. MLPs also raised approximately $23 billion of debt capital during the period. Most MLPs pay out the majority of excess cash flow as distributions to investors, and therefore must raise external capital to fund growth projects and to fund acquisitions.

MACRO REVIEW

West Texas Intermediate (WTI) crude oil prices ended the reporting period at $49.44 per barrel, up 19% from the prior year. Global crude prices, as measured by Brent crude oil, traded 13% higher over the reporting period. The crude oil price improvement appears linked to the continued moderation in U.S. crude production, healthy demand growth, and the aforementioned OPEC deal to reduce supply. Brent exited the period at a $1 per barrel premium to WTI, which is near the historic norm. However, this reversion represents a departure from the $8 to $9 per barrel Brent premium that has generally existed since 2009.

Henry Hub natural gas spot prices exited the period at $3.30 per million British thermal units (“mmbtu”), up 58% over the reporting period. Natural gas pricing has benefited from a long awaited realignment of supply-demand in which natural gas usage as a heating and electric generation fuel has increased as gas production volume growth has declined, and as increased exports have become a reality via both liquefied natural gas and new pipelines to Mexico.

Mont Belvieu NGL prices ended the reporting period at $23.92 per barrel, a 26% increase over the reporting period. All of the NGL purity products ended the period higher than the same time in the prior year. Frac spreads, a measure of natural gas processing economics, ended the period at $0.28 per gallon, up 4% over the reporting period. Generally, the greater the frac spread, the greater the incentive for producers to seek natural gas processing capacity.

The yield curve modestly flattened over the reporting period as short rates rose more than the yields on longer-dated maturities. The ten-year Treasury yield rose 18 basis points to end the period at 2.38%. The MLP yield spread at period-end, as

4 OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND

measured by the AMZ and the 10-year Treasury bond, narrowed by 115 basis points to 5.05%.

Over the reporting period, real estate investment trusts (“REITs”) and utilities, two competing yield-oriented equity asset classes, posted total returns of 5.65% (as measured by the Dow Jones Equity REIT Total Return Index) and 16.31% (as measured by the Dow Jones Utility Average Index), respectively, as compared to the AMZ’s 9.28% total return. Price to forward distributable cash flow (DCF), a commonly watched ratio within the MLP sector, increased over the period but remains below the ten-year average.

SUBSECTOR REVIEW

Performance among subsectors in the midstream, or energy infrastructure, MLP asset class varied for the reporting period. On average, the gathering and processing subsector provided the best performance over the period, buoyed by improving commodity prices supporting improved volumetric projections. The natural gas pipeline group followed as investors continued to express preference for long-haul natural gas pipelines, particularly those backed by utility demand pull.

The marine subsector experienced the weakest performance over the reporting period as several entities substantially reduced cash distributions to investors. The propane subsector also lagged over the reporting period as market participants appeared to rotate out of the subsector in favor of more traditional midstream names and as rising propane prices could result in some margin pressure in future periods.

FUND REVIEW

Key contributors to the Fund were Williams Partners, LP (WPZ) and Tallgrass Energy GP, LP (TEGP).

WPZ units outperformed over the period after the proposed merger with Energy Transfer was terminated in late June and the Williams enterprise subsequently focused on strengthening its balance sheet, improving liquidity, and preserving its investment grade credit rating. During the period The Williams Companies (WMB) began execution of plans to reinvest $1.7 billion into WPZ, its daughter partnership, via a private purchase of common units and a concurrently announced distribution reinvestment program (“DRIP”). The Williams family also announced a restructuring of gathering agreements that served to reduce counterparty risk and the sale of Canadian assets that raised $1 billion in cash proceeds.

TEGP units outperformed over the period as the general partner’s underlying operating partnership, Tallgrass Energy Partners (TEP), reaffirmed annual distribution growth guidance of at least 20% for the period of 2015 through 2017. Additionally, the partnership’s sponsor announced an agreement to acquire additional interests in the Rockies Express Pipeline, which aids longer-term growth prospects. Notably, TEGP’s board approved a $100 million buyback program of TEP or TEGP units.

OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND 5

Key detractors from the Fund were Energy Transfer Equity LP (ETE) and The Williams Companies (WMB).

Both ETE and WMB units detracted from performance over the reporting period on investor concern over the planned merger of ETE and WMB. After the merger was terminated in late June, each entity executed measures to support their respective daughter partnerships, some at the expense of current parent cash flows. While the equity price performance of both entities lagged over the reporting period, each has recovered substantially from the lows.

Separately, the Fund also obtains leverage through borrowing, which did not produce a significant impact to its performance this reporting period. Please note that to the extent the Fund obtains leverage through borrowing, there will be the potential for greater gains and the risk of magnified losses.

Please note that significant decreases in cash distributions from the Fund’s MLP investments and/or significant declines in the fair value of its investments may impact the Fund’s assessment regarding the recoverability of certain deferred tax assets, which may result in the recording of a valuation allowance. If a valuation allowance is established, this could have a material impact on the Fund’s net asset value and results of operations for the period. The Fund had a valuation allowance in place throughout the entire reporting period. See Note 2 of the Notes to Financial Statements for more information.

OUTLOOK

We believe we have seen the worst of this energy market down cycle. The rate of midstream growth will likely moderate from peak levels, but average distributions are still likely to grow. Midstream operators may also stand to benefit as they make more efficient use of their existing assets. We believe current market valuations underestimate the potential for renewed business growth going forward and remain optimistic on the sector’s prospects. For this reason, we believe MLPs continue to offer attractive total return potential based on the potential for price appreciation and stable or growing distribution streams.

The Fund’s performance is compared to the performance of the S&P 500 Index and the Alerian MLP Index. The S&P 500 Index is a broad-based measure of domestic stock performance. The Alerian MLP Index is a composite of the 50 most prominent Master Limited Partnerships that provides investors with an unbiased, comprehensive benchmark for this emerging asset class. The Alerian MLP Index, which is calculated using a float-adjusted, capitalization-weighted methodology, is disseminated real-time on a total-return basis. The indices are 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 indices. Index performance includes reinvestment of income, but does not reflect transaction costs, fees, expenses or

8 OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND

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 Fund’s investment strategy and focus can change over time. The mention of specific fund holdings does not constitute a recommendation by OppenheimerFunds, Inc. or its affiliates.

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 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 November 30, 2016.

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 November 30, 2016” 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). 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.

Returns do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. The returns do not include adjustments in accordance with generally accepted accounting principles required at the period end for financial reporting purposes.

5. Annualized for less than full year.

6. Includes interest, borrowing and franchise tax expense. Without interest, borrowing and franchise tax expense, the net expense ratio would be 1.66%, 1.61%, 1.74% and 1.75%, for the years ended November 30, 2016, November 30, 2015, November 28, 2014, and November 29, 2013, respectively.

7. Includes interest expense. Without interest expense the net expense ratio would be 1.75%.

8. Deferred tax expense estimate for the ratio calculation is derived from the net investment income/loss, and realized and unrealized gains/losses.

9. Effective December 1, 2013 the deferred tax expense and deferred tax benefit are allocated based on average net assets. Prior to December 1, 2013 the deferred tax expense and deferred tax benefit were allocated based on specific class expenses.

10. Deferred tax benefit for the ratio calculation is derived from net investment income/loss only.

NOTES TO FINANCIAL STATEMENTS

1. Organization

Oppenheimer SteelPath MLP Alpha Plus Fund (the “Fund”), a separate series of Oppenheimer SteelPath MLP Funds Trust, is a non-diversified open-end management investment company registered under the Investment Company Act of 1940, as amended. The Fund’s investment objective is to seek total return. The Fund’s investment adviser is OFI SteelPath, Inc. (the “Adviser” or “Manager”), a wholly-owned subsidiary of OppenheimerFunds, Inc. (“OFI” or “Oppenheimer”).

The Fund offers Class A, Class C, Class I, and Class Y shares. Effective June 28, 2013, Class I shares were renamed Class Y shares. Class A shares are sold at their offering price, which is normally net asset value plus a front-end sales charge. Effective June 28, 2013 although there is no initial sales charge on Class A purchases totaling $1 million or more, those Class A shares may be subject to a 1.00% contingent deferred sales charge (”CDSC”) if shares are redeemed within an 18-month “holding period” measured from the date of purchase. Class C shares are sold without a front-end sales charge but may be subject to a CDSC of 1.00% of the redemption proceeds if Class C shares are redeemed within one year of purchase. Class I shares are only available to eligible institutional investors. Class I shares are sold at net asset value per share without a sales charge or CDSC. An institutional investor that buys Class I shares for its customers’ accounts may impose charges on those accounts. Class Y shares are sold at net asset value per share without a sales charge directly to institutional investors that have special agreements with OppenheimerFunds Distributor, Inc. (the “Distributor”) for that purpose. They may include insurance companies, registered investment companies, employee benefit plans and section 529 plans, among others. An institutional investor that buys Class Y shares for its customers’ accounts may impose charges on those accounts. All classes of shares have identical rights and voting privileges with respect to the Fund in general and exclusive voting rights on matters that affect that class alone. Earnings, net assets and net asset value per share may differ due to each class having its own expenses, such as transfer and shareholder servicing agent fees and shareholder communications, directly attributable to that class. Class A and C shares have separate distribution and/or service plans under which they pay fees. Class I and Y shares do not pay such fees.

The Fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standard Codification Topic 946 Financial Services- Investment Companies.

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”).

OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND 23

NOTES TO FINANCIAL STATEMENTS (Continued)

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. generally accepted accounting principles, are recorded on the ex-dividend date. Dividends, if any, are declared and distributed monthly for the Fund. The estimated characterization of the distributions paid will be either a qualified dividend or distribution (return of capital). This estimate is based on the Fund’s operating results during the period. It is anticipated that a significant portion of the distributions will be comprised of return of capital as a result of the tax character of cash distributions made by the Fund’s investments. The actual characterization of the distributions made during the period will not be determined until after the end of the fiscal year. The Fund will inform shareholders of the final tax character of the distributions on IRS Form 1099 DIV in February 2017. For the year ended November 30, 2016, the Fund distributions are expected to be comprised of 100% return of capital.

Return of Capital Estimates. Distributions received from the Fund’s investments in MLPs generally are comprised of income and return of capital. The Fund records investment income and return of capital based on estimates made at the time such distributions are received. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on information received from MLPs after their tax reporting periods are concluded. For the year ended November 30, 2016, the Fund estimated that 100% of the MLP distributions received would be treated as 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 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, if applicable, are amortized or accreted daily.

Custodian Fees. “Custody fees” 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

24 OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

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 using 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 Income Taxes. The Fund does not intend to qualify as a regulated investment company pursuant to Subchapter M of the Internal Revenue Code, but will rather be taxed as a corporation. As a corporation, the Fund is obligated to pay federal, state and local income tax on taxable income. Currently, the maximum marginal regular federal income tax rate for a corporation is 35 percent. Upon enactment, a change in the federal income tax rate could have a material impact to the Fund. The Fund may be subject to a 20 percent alternative minimum tax on its federal alternative minimum taxable income to the extent that its alternative minimum tax exceeds its regular federal income tax. The Fund is currently using an estimated rate of 1.7 percent for state and local tax, net of federal tax expense.

The Fund’s income tax provision consists of the following as of November 30, 2016:

Current tax expense (benefit)
Federal	$	—
State		—
Total current tax expense	$	—
Deferred tax expense (benefit)
Federal	$	2,187,331
State		206,908
Total deferred tax expense	$	2,394,239

OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND 25

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

The reconciliation between the federal statutory income tax rate of 35% and the effective tax rate on net investment income (loss) and realized and unrealized gain (loss) follows:

	Amount			Rate
Application of federal statutory income tax rate	$	5,851,985			35.00	%
State income taxes net of federal benefit		284,239			1.70	%
Effect of state tax rate change		100,667			0.60	%
Effect of permanent differences		(77,350	)		(0.46	%)
Change in valuation allowance		(3,765,302	)		(22.52	%)
Total income tax expense (benefit)	$	2,394,239			14.32	%

For the year ended November 30, 2016 the Fund’s effective tax rate of 14.32% (net expense) differed from the combined federal and state statutory tax rate of 36.70% (net expense) mainly due to the change in valuation allowance primarily as a result of the change in unrealized appreciation.

The Fund intends to invest its assets primarily in MLPs, which generally are treated as partnerships for federal income tax purposes. As a limited partner in the MLPs, the Fund reports its allocable share of the MLP’s taxable income in computing its own taxable income. The Fund’s tax expense or benefit will be included in the Statement of Operations based on the component of income or gains (losses) to which such expense or benefit relates. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Such temporary differences are principally: (i) taxes on unrealized gains/(losses), which are attributable to the temporary difference between fair market value and tax basis, (ii) the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes and (iii) the net tax benefit of accumulated net operating losses and capital loss carryforwards. Deferred tax assets and liabilities are measured using effective tax rates expected to apply to taxable income in the years such temporary differences are realized or otherwise settled. To the extent the Fund has a deferred tax asset, consideration is given to whether or not a valuation allowance is required. A valuation allowance is required if, based on the evaluation criterion provided by ASC 740, Income Taxes (ASC 740), it is more-likely-than-not some portion or all of the deferred tax asset will not be realized. Among the factors considered in assessing the Fund’s valuation allowance are: the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of the statutory carryforward periods, significant redemptions, and the associated risks that operating and capital loss carryforwards may expire unused.

26 OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

At November 30, 2016, the Fund determined a valuation allowance was required. In implementing a valuation allowance on a portion of the deferred tax asset, significant consideration was given to the current and expected level of MLP distributions, unrealized gains and losses on MLP investments and the expiration dates for net operating losses and capital loss carryovers. Market cycles, the severity and duration of historical deferred tax assets and the impact of current and future redemptions were also considered. Through the consideration of these factors, the Fund has determined that it is more likely than not the deferred tax asset, net of the valuation allowance, will be realized.

Unexpected significant decreases in cash distributions from the Fund’s MLP investments, significant declines in the fair value of its investments, significant redemptions, or increased risk of expiring net operating losses or capital loss carryovers may change the Fund’s assessment regarding the recoverability of its deferred tax assets and may result in a change to the valuation allowance. Modifications of the valuation allowance could have a material impact on the Fund’s net asset value.

Components of the Fund’s deferred tax assets and liabilities as of November 30, 2016 are as follows:

Deferred tax assets:
Net operating loss carryforward (tax basis)	$	13,124,432
Capital loss carryforward (tax basis)		32,996,530
Book to tax differences - Income recognized from MLPs		697,667
Valuation allowance		(16,329,331	)
Total deferred tax asset		30,489,298
Deferred tax liabilities:
Net unrealized gains on investment securities (tax basis)		(15,370,464	)
Total deferred tax liability		(15,370,464	)
Total net deferred tax asset/(liability)	$	15,118,834

The Fund may rely, to some extent, on information provided by the MLPs, which may not necessarily be timely, to estimate taxable income allocable to MLP units held in its portfolio, and to estimate its associated deferred tax liability or asset. Such estimates are made in good faith. From time to time, as new information becomes available, the Fund will modify its estimates or assumptions regarding its tax liability or asset.

OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND 27

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

The Fund’s policy is to classify interest and penalties associated with underpayment of federal and state income taxes, if any, as income tax expense on its Statement of Operations. As of November 30, 2016, the Fund does not have any interest or penalties associated with the underpayment of any income taxes.

The Fund files income tax returns in the U.S. federal jurisdiction and various states. The Fund has reviewed all major jurisdictions and concluded that there is no significant impact on the Fund’s net assets and no tax liability resulting from unrecognized tax benefits relating to uncertain tax positions expected to be taken on its tax returns. Furthermore, management of the Fund is not aware of any uncertain tax positions for which it is reasonably possible that the total amount of unrecognized tax benefit will significantly change in the next 12 months.

At November 30, 2016, the Fund had net operating loss carryforwards for federal income tax purposes, which may be carried forward for 20 years, as follows:

Expiration Date
11/30/2032	$	30,185
11/30/2033		2,160,318
11/30/2034		12,911,167
11/30/2035		6,544,238
11/30/2036		14,115,488
Total	$	35,761,396

At November 30, 2016, the Fund had net capital loss carryforwards for federal income tax purposes, which may be carried forward for 5 years, as follows:

Expiration Date
11/30/2020	$	43,028,252
11/30/2021		46,880,550
Total	$	89,908,802

At November 30, 2016, gross unrealized appreciation and depreciation of investments, based on cost for federal income tax purposes were as follows:

Cost of Investments	$	268,239,877
Gross Unrealized Appreciation	$	63,784,324
Gross Unrealized Depreciation		(21,723,570	)
Net Unrealized Appreciation (Depreciation) on Investments	$	42,060,754

28 OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND

NOTES TO FINANCIAL STATEMENTS (Continued)

2. Significant Accounting Policies (Continued)

The difference between cost amounts for financial statement and federal income tax purposes is due primarily to timing differences in recognizing certain gains and losses in security transactions.

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.

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 of Trustees (the “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 Adviser. The Adviser 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:

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. If the official closing price or last sales 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

OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND 29

NOTES TO FINANCIAL STATEMENTS (Continued)

3. Securities Valuation (Continued)

exchange or two dealers, the security is valued by using one of the following methodologies (listed in order of priority): (1) 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 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.

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 Adviser, 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 Adviser’s Valuation Committee. The Valuation Committee considers all relevant facts that are reasonably available, through either public information or information available to the Adviser, when determining the fair value of a security. Fair value determinations by the Adviser are subject

30 OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND

NOTES TO FINANCIAL STATEMENTS (Continued)

3. Securities Valuation (Continued)

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 Adviser, or its third party service provider who is subject to oversight by the Adviser, 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.)

3) Level 3-significant unobservable inputs (including the Adviser’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 did not hold any Level 3 securities during the year ended November 30, 2016.

There have been no transfers between pricing levels for the Fund. It is the Fund’s policy to recognize transfers at the beginning of the reporting period.

4. Investments and Risks

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

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

Master Limited Partnerships (“MLPs”). Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowings for investment purposes) in the equity securities of MLPs.

32 OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND

NOTES TO FINANCIAL STATEMENTS (Continued)

4. Investments and Risks (Continued)

MLPs issue common units that represent an equity ownership interest in a partnership and provide limited voting rights. MLP common units are registered with the Securities and Exchange Commission (“SEC”), and are freely tradable on securities exchanges such as the NYSE and the NASDAQ Stock Market (“NASDAQ”), or in the over-the-counter (“OTC”) market. An MLP consists of one or more general partners, who conduct the business, and one or more limited partners, who contribute capital. MLP common unit holders have a limited role in the partnership’s operations and management. The Fund, as a limited partner, normally would not be liable for the debts of the MLP beyond the amounts the Fund has contributed, but would not be shielded to the same extent that a shareholder of a corporation would be. In certain circumstances creditors of an MLP would have the right to seek return of capital distributed to a limited partner. This right of an MLP’s creditors would continue after the Fund sold its investment in the MLP.

Concentration Risk. Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of borrowing for investment purposes) in the equity securities of MLPs. MLPs are subject to certain risks, such as supply and demand risk, depletion and exploration risk, commodity pricing risk, acquisition risk, and the risk associated with the hazards inherent in midstream energy industry activities. A substantial portion of the cash flow received by the Fund is derived from investment in equity securities of MLPs. The amount of cash that a MLP has available for distributions, and the tax character of such distributions, are dependent upon the amount of cash generated by the MLP’s operations.

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.

OPPENHEIMER STEELPATH MLP ALPHA PLUS FUND 33

NOTES TO FINANCIAL STATEMENTS (Continued)

5. Market Risk Factors (Continued)

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

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

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

6. 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:

8. Fees and Other Transactions with Affiliates (Continued)

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 with respect to these services are detailed in the Statement of Operations.

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 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, if applicable. 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, 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 under Rule 12b-1 of the Investment Company Act of 1940. 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.

8. Fees and Other Transactions with Affiliates (Continued)

Distribution and Service Plans for Class C Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for Class C shares under Rule 12b-1 of the Investment Company Act of 1940 to compensate the Distributor for distributing those share classes, maintaining accounts and providing shareholder services. Under the Plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class C shares daily net assets. The Fund also pays a service fee under the Plans at an annual rate of 0.25% of daily net assets.

The Plan and Plans continue in effect from year to year only if the Fund’s Board votes annually to approve their continuance at an in person meeting called for that purpose. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations.

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

Year Ended	Class A Front-End Sales Charges Retained by Distributor		Class C Contingent Deferred Sales Charges Retained by Distributor
November 30, 2016	$	50,740	$	7,177

Waivers and Reimbursements of Expenses. The Manager has contractually agreed to limit fees and/or reimburse expenses of the Fund to the extent that the Fund’s total annual fund operating expenses (exclusive of interest, taxes, such as deferred tax expenses, brokerage commissions, acquired fund fees and expenses, dividend costs related to short sales, litigation expense, if any) exceed 2.00% for Class A shares, 2.75% for Class C shares, and 1.75% for Class Y shares. The Fund’s total annual operating expenses after fee waiver and/or expense reimbursement (“Net Expenses”) will be higher than these amounts to the extent that the Fund incurs expenses excluded from the expense cap. Because the Fund’s deferred income tax expense/(benefit), borrowing fees, and interest expense are excluded from the expense cap, the Fund’s Net Expenses for each class of shares is increased/(decreased) by the amount of these expenses. This undertaking may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein, unless approved by the Trust’s Board of Trustees.

8. Fees and Other Transactions with Affiliates (Continued)

The Manager can be reimbursed by the Fund within three years after the date the fee limitation and/or expense reimbursement has been made by the Manager, provided that such repayment does not cause the expenses of any class of the Fund to exceed the foregoing limits.

During the year ended November 30, 2016, the Adviser did not waive any expenses and does not have any previously waived expenses eligible for recovery.

Related Party. The Interested Trustees and officers of the Fund are also officers or trustees of companies affiliated with the Manager, Distributor, and Transfer Agent.

9. Borrowing Agreement

The Fund, along with Oppenheimer SteelPath MLP Alpha Fund, Oppenheimer SteelPath MLP Income Fund, and Oppenheimer SteelPath MLP Select 40 Fund (collectively, the “Trust”), is a borrower in a $700 million revolving credit agreement (the “Loan Agreement”) with a major lending institution (the “Lender”). The Fund is permitted to borrow up to the lesser of one-third of the Fund’s total assets, or the maximum amount permitted pursuant to the Fund’s investment limitations. Amounts borrowed under the Loan Agreement, if any, are invested by the Fund under the direction of the Manager consistent with the Fund’s investment objective and policies, and as such, the related investments are subject to normal market fluctuations and investment risks, including the risk of loss due to a decline in value. The borrowing, if any, is fully collateralized throughout the term of the borrowing with securities or other assets of the Fund. The Fund is not liable for borrowings of other Funds in the Trust. Securities that have been pledged as collateral for the borrowing are indicated in the Statement of Investments.

Borrowings under the Loan Agreement are charged interest at a calculated rate computed by the Lender based on the one month LIBOR rate plus 0.65% per annum. An unused commitment fee at the rate of 0.125% per annum is charged for any undrawn portion of the credit facility, and each member of the Trust will pay its pro rata share of this fee. A facility fee of 0.20% was charged on the commitment amount, and each party of the Trust paid its pro rata share of this fee. The borrowing is due November 17, 2017, unless another date is mutually agreed upon by the parties of the Loan Agreement. For the year ended November 30, 2016, the Fund paid $374,604 in borrowing fees. The payable on borrowing balance and interest rate at November 30, 2016 was $74,000,000 and 1.27%, respectively.

10. Pending Litigation

In 2009, several putative class action lawsuits were filed and later consolidated before the U.S. District Court for the District of Colorado in connection with the investment performance of Oppenheimer Rochester California Municipal Fund (the “California Fund”), a fund advised by OppenheimerFunds, Inc. (“OFI”) – the parent company of the manager and distributed by OppenheimerFunds Distributor, Inc. (“OFDI”) . The plaintiffs asserted claims against OFI, OFDI and certain present and former trustees and officers of the California Fund under the federal securities laws, alleging, among other things, that the disclosure documents of the California Fund contained misrepresentations and omissions and the investment policies of the California Fund were not followed. An amended complaint and a motion to dismiss were filed, and in 2011, the court issued an order which granted in part and denied in part the defendants’ motion to dismiss. In October 2015, following a successful appeal by defendants and a subsequent hearing, the court granted plaintiffs’ motion for class certification and appointed class representatives and class counsel.

OFI and OFDI believe the suit is without merit; that it is premature to render any opinion as to the likelihood of an outcome unfavorable to them in the Suit; and that no estimate can yet be made as to the amount or range of any potential loss. Furthermore, OFI believes that the suit should not impair the ability of OFI or OFDI to perform their respective duties to the Fund and that the outcome of the suit should not have any material effect on the operations of any of the Oppenheimer funds.

BOARD APPROVAL OF THE FUND’S INVESTMENT
ADVISORY AGREEMENT Unaudited

The Fund has entered into an investment advisory agreement (the “Agreement”) with OFI SteelPath, Inc. (“OFI SteelPath” or the “Manager”). Each year, the Board of Trustees (the “Board”), including a majority of the independent Trustees, is required to determine whether to approve the terms of the Agreement and the renewal thereof. The Investment Company Act of 1940, as amended, requires that the Board request and evaluate, and that the Manager provide, such information as may be reasonably necessary to evaluate the terms of the Agreement. The Board employs an independent consultant to prepare a report that provides information, including comparative information that the Board requests for that purpose. In addition to in-person meetings focused on this evaluation, the Board receives information throughout the year regarding Fund services, fees, expenses and performance.

The Manager and the independent consultant provided information to the Board on the following factors: (i) the nature, quality and extent of the Manager’s services, (ii) the comparative investment performance of the Fund and the Manager, (iii) the fees and expenses of the Fund, including comparative fee and expense information, (iv) the profitability of the Manager and its 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 Manager from its relationship with the Fund. The Board was aware that there are alternatives to retaining the Manager.

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 Manager’s key personnel who provide such services. The Manager’s duties include providing the Fund with the services of the portfolio managers and investment team, who provide research, analysis and other advisory services in regard to the Fund’s investments; and securities trading services. The Manager is responsible for 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 Manager is also responsible for providing certain administrative services to the Fund. Those services, some of which are performed by affiliates of the Manager, 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 U.S. Securities and Exchange Commission; preparing periodic reports regarding the operations of the Fund for its shareholders; preparing proxy materials for shareholder meetings; and preparing the registration statements required by federal and state securities laws for the sale of the Fund’s shares. The Manager also provides the Fund with office space, facilities and equipment.

BOARD APPROVAL OF THE FUND’S INVESTMENT
ADVISORY AGREEMENT Unaudited / (Continued)

The Board also considered the quality of the services provided and the quality of the Manager’s resources that are available to the Fund. In evaluating the Manager, the Board considered the history, reputation, qualification and background of the Manager, including its corporate parent, OppenheimerFunds, Inc. (“OFI”) and corporate affiliate, OFI Global Asset Management, Inc. (“OFI Global” and OFI and OFI Global are collectively referred to hereinafter as “OFI”), and the fact that OFI has over 50 years of experience as an investment adviser and that its assets under management rank it among the top mutual fund managers in the United States. The Board evaluated the Manager’s and OFI’s advisory, administrative, accounting, legal, compliance and risk management services, and information the Board has received regarding the experience and professional qualifications of the Manager’s and OFI’s 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 Stuart Cartner and Brian Watson, the portfolio managers for the Fund, and the Manager’s investment team and analysts. The Board members also considered the totality of their experiences with the Manager and OFI as trustees of the Fund and other funds advised by the Manager or OFI. The Board considered information regarding the quality of services provided by affiliates of the Manager, which the Board members have become knowledgeable about through their experiences with the Manager or OFI and in connection with the renewal of the Fund’s service agreements. The Board concluded, in light of the Manager’s and OFI’s experience, reputation, personnel, operations and resources that the Fund benefits from the services provided under the Agreement.

Investment Performance of the Manager and the Fund. Throughout the year, the Manager provided information on the investment performance of the Fund and the Manager, including comparative performance information. The Board also reviewed information, prepared by the Manager and by the independent consultant, comparing the Fund’s historical performance to relevant market indices and to the performance of other retail energy limited partnership funds. The Board noted that the Fund’s performance for the three-year period was equal to that of its performance category median, although its performance for the one-year period was lower than its performance category median. The Board considered the Manager’s assertion that energy markets continued to struggle throughout 2015 under a historically sharp and prolonged crude oil price correction and, as a result, the debt and equity capital markets for energy companies experienced severe disruption. The Board noted the Fund’s performance has improved since February 2016, and that the Fund outperformed its category for the year-to-date period ended June 30, 2016.

Fees and Expenses of the Fund. The Board reviewed the fees paid to the Manager and the other expenses borne by the Fund. The independent consultant provided comparative data in regard to the fees and expenses of the Fund and other retail energy limited partnership funds with comparable asset levels and distribution features. The Board noted that the Fund’s contractual management fee was higher than its peer group median and category median. The Board also noted that the Fund’s total expenses were higher than its peer group median and category median. The Board considered that the Fund’s contractual management fee includes

BOARD APPROVAL OF THE FUND’S INVESTMENT
ADVISORY AGREEMENT Unaudited / (Continued)

both the advisory fee and the administrative fee, which contribute to the Fund’s costs and noted that the administrative fee reflects the complex tax work associated with the Fund’s master limited partnership (“MLP”) investments. The Board further considered that the Fund strategically employs leverage to attempt to enhance returns and to seek to offset the deferred tax expenses. The Board also considered management’s assertion that the Fund ranks poorly within its peer group, since other funds in the group do not employ leverage as an investment technique. In this regard, the Board considered the Manager’s assertion that closed-end funds that invest in MLPs and employ leverage provide a more appropriate comparison, and noted that the Fund’s total expense ratio is the lowest among the top five (ranked by assets under management) closed-end, levered, MLP funds. The Board noted that the Manager has contractually agreed to waive fees and/or reimburse the Fund so that total expenses, as a percentage of average daily net assets, will not exceed the following annual rates: 2.00% for Class A shares, 2.75% for Class C shares and 1.75% for Class Y shares. The fee limitation may not be amended or withdrawn prior to its expiration on March 30, 2017, unless approved by the Board.

Economies of Scale and Profits Realized by the Manager. The Board considered information regarding the Manager’s costs in serving as the Fund’s investment adviser, including the costs associated with the personnel and systems necessary to manage the Fund, and information regarding the Manager’s profitability from its relationship with the Fund. The Board also considered that the Manager must be able to pay and retain experienced professional personnel at competitive rates to provide quality services to the Fund. The Board reviewed whether the Manager may 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 Manager. In addition to considering the profits realized by the Manager, the Board considered information that was provided regarding the direct and indirect benefits the Manager receives as a result of its relationship with the Fund, including compensation paid to the Manager’s affiliates and research provided to the Manager in connection with permissible brokerage arrangements (soft dollar arrangements).

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 Manager within the meaning and intent of the Securities and Exchange Commission Rules.

Based on its review of the information it received and its evaluations described above, the Board, including a majority of the independent Trustees, decided to continue the Agreement through August 31, 2017. 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 Agreement, including the management fees, in light of all the surrounding circumstances.

DISTRIBUTION SOURCES Unaudited

For any distribution that took place over the last six months of the Fund’s reporting period, the table below details, on a per-share basis, the percentage of the Fund’s total distribution payment amount that was derived from the following sources: net income, net profit from the sale of securities, and other capital sources. This information is based upon income and capital gains using generally accepted accounting principles as of the date of each distribution. For certain securities, such as Master Limited Partnerships (“MLPs”), the percentages attributed to each category are estimated using historical information because the character of the amounts received from the MLPs in which the Fund invests is unknown until after the end of the calendar year. Because the Fund is actively managed, the relative amount of the Fund’s total distributions derived from various sources over the calendar year may change. Please note that this information should not be used for tax reporting purposes as the tax character of distributable income may differ from the amounts used for this notification. You will receive IRS tax forms in the first quarter of each calendar year detailing the actual amount of the taxable and non-taxable portion of distributions paid to you during the tax year.

For the most current information, please go to oppenheimerfunds.com. Select your Fund, then the ’Detailed’ tab; where ‘Dividends’ are shown, the Fund’s latest pay date will be followed by the sources of any distribution, updated daily.

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.
