NOTES TO FINANCIAL STATEMENTS

June 30, 2018

(unaudited)

NOTE 1 – ORGANIZATION

ProShares Trust II (the “Trust”) is a Delaware statutory trust formed on October 9, 2007 and is currently organized into separate series (each, a “Fund” and collectively, the “Funds”). As of June 30, 2018, the following twenty series of the Trust have commenced investment operations: (i) ProShares VIX Short-Term Futures ETF and ProShares VIX Mid-Term Futures ETF (each, a “Matching VIX Fund” and collectively, the “Matching VIX Funds”); (ii) ProShares Short VIX Short-Term Futures ETF and ProShares Ultra VIX Short-Term Futures ETF (each, a “Geared VIX Fund” and collectively, the “Geared VIX Funds”); (iii) ProShares UltraShort Bloomberg Crude Oil, ProShares UltraPro 3x Short Crude Oil ETF, ProShares UltraShort Bloomberg Natural Gas, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Australian Dollar, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Crude Oil, ProShares UltraPro 3x Crude Oil ETF, ProShares Ultra Bloomberg Natural Gas, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen (each, a “Leveraged Fund” and collectively, the “Leveraged Funds”); and (iv) ProShares Short Euro (the “Short Euro Fund”). Each of the Funds listed above issues common units of beneficial interest (“Shares”), which represent units of fractional undivided beneficial interest in and ownership of only that Fund. The Shares of each Fund are listed on the New York Stock Exchange Archipelago (“NYSE Arca”). The Leveraged Funds, the Short Euro Fund and the Geared VIX Funds, are collectively referred to as the “Geared Funds” in these Notes to Financial Statements. The Geared VIX Funds and the Matching VIX Funds are collectively referred to as the “VIX Funds” in these Notes to Financial Statements.

The Trust had no operations prior to November 24, 2008, other than matters relating to its organization, the registration of each series under the Securities Act of 1933, as amended, and the sale and issuance to ProShare Capital Management LLC (the “Sponsor”) of fourteen Shares at an aggregate purchase price of $350 in each of the following Funds: ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Crude Oil, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen.

Groups of Funds are collectively referred to in several different ways. References to “Short Funds,” “UltraShort Funds,” “UltraPro Short Funds,” “Ultra Funds,” or “UltraPro Funds” refer to the different Funds based upon their investment objectives, but without distinguishing among the Funds’ benchmarks.

References to “Commodity Index Funds,” “Commodity Funds” and “Currency Funds” refer to the different Funds according to their general benchmark categories without distinguishing among the Funds’ investment objectives or Fund-specific benchmarks. References to “VIX Funds” refer to the different Funds based upon their investment objective and their general benchmark categories.

Effective as of close of business on February 27, 2018, the investment objective of ProShares Ultra VIX Short-Term Futures ETF and ProShares Short VIX Short-Term Futures ETF changed.

ProShares Ultra VIX Short-Term Futures ETF changed its investment objective to seek daily investment results, before fees and expenses, that correspond to one and one-half times (1.5x) of the performance of the S&P 500 VIX Short-Term Futures Index for a single day. Prior to the close of business on February 27, 2018, the Fund’s investment objective was to seek results, before fees and expenses, that correspond to two times (2x) the performance of the Index for a single day.

ProShares Short VIX Short-Term Futures ETF changed its investment objective to seek daily investment results, before fees and expenses, that correspond to one-half the inverse (-0.5x) of the performance of the S&P 500 VIX Short-Term Futures Index for a single day. Prior to the close of business on February 27, 2018, the Fund’s investment objective was to seek results, before fees and expenses, that correspond to the inverse (-1x) of the Index for a single day.

Each “Short” Fund seeks daily investment results, before fees and expenses, that correspond to either one-half inverse (-0.5x) or inverse (-1x) of the daily performance of its corresponding benchmark. Each “UltraShort” Fund seeks daily investment results, before fees and expenses, that correspond to two times the inverse (-2x) of the daily performance of its corresponding benchmark. Each

108

“UltraPro Short” Fund seeks daily investment results, before fees and expenses, that correspond to three times the inverse (-3x) of the daily performance of its corresponding benchmark. Each “Ultra” Fund seeks daily investment results, before fees and expenses, that correspond to either one and one-half times (1.5x) or two times (2x) the daily performance of its corresponding benchmark. Each “UltraPro” Fund seeks daily investment results, before fees and expenses, that correspond to three times (3x) the daily performance of its corresponding benchmark. Each Matching VIX Fund seeks investment results, before fees and expenses, that match the performance of its corresponding benchmark. Daily performance is measured from the calculation of one NAV to the next.

The Geared Funds do not seek to achieve their stated investment objective over a period of time greater than a single day because mathematical compounding prevents the Geared Funds from achieving such results. Accordingly, results over periods of time greater than a single day should not be expected to be a simple multiple (e.g., -0.5x, -1x, -2x, 1.5x, 2x, -3x or 3x) of the period return of the corresponding benchmark and will likely differ significantly.

As described in the prospectus for each Fund, each of the Funds intends to invest in financial instruments “Financial Instruments” (Financial Instruments are instruments whose value is derived from the value of an underlying asset, rate or benchmark, including futures contracts, swap agreements, forward contracts and other instruments) as a substitute for investing directly in commodities, currencies, or spot volatility products in order to gain exposure to the VIX Index, natural gas, crude oil, precious metals, or currencies, as applicable. Financial Instruments also are used to produce economically “inverse,” “inverse leveraged” or “leveraged” investment results for the Geared Funds.

The reverse splits were applied retroactively for all periods presented, reducing the number of Shares outstanding for each of the Funds, and resulted in a proportionate increase in the price per Share and per Share information of each such Fund. Therefore, the reverse splits did not change the aggregate net asset value of a shareholder’s investment at the time of the reverse split.

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

Each Fund is an investment company, as defined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946 “Financial Services — Investment Companies.” As such, the Funds follow the investment company accounting and reporting guidance. The following is a summary of significant accounting policies followed by each Fund, as applicable, in preparation of its financial statements. These policies are in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Certain prior year amounts have been reclassified to conform to the current year presentation.

109

The accompanying unaudited financial statements were prepared in accordance with GAAP for interim financial information and with the instructions for Form 10-Q and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). In the opinion of management, all material adjustments, consisting only of normal recurring adjustments, considered necessary for a fair statement of the interim period financial statements have been made. Interim period results are not necessarily indicative of results for a full-year period. These financial statements and the notes thereto should be read in conjunction with the Trust’s and the Funds’ financial statements included in the Trust’s Annual Report on Form 10-K/A for the year ended December 31, 2017, as filed with the SEC on March 26, 2018.

Use of Estimates & Indemnifications

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

In the normal course of business, the Trust enters into contracts that contain a variety of representations which provide general indemnifications. The Trust’s maximum exposure under these arrangements cannot be known; however, the Trust expects any risk of loss to be remote.

Basis of Presentation

Pursuant to rules and regulations of the SEC, audited financial statements are presented for the Trust as a whole, as the SEC registrant, and for each Fund individually. The debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to a particular Fund shall be enforceable only against the assets of such Fund and not against the assets of the Trust generally or any other Fund. Accordingly, the assets of one Fund of the Trust include only those funds and other assets that are paid to, held by or distributed to the Trust for the purchase of Shares in that Fund.

Statement of Cash Flows

The cash amount shown in the Statements of Cash Flows is the amount reported as cash in the Statement of Financial Condition dated June 30, 2018, and represents cash, segregated cash balances with brokers for futures contracts, segregated cash with brokers for swap agreements, segregated cash with brokers for forward agreements, and segregated cash with brokers for foreign currency forward agreements but does not include short-term investments.

Final Net Asset Value for Fiscal Period

The cut-off times and the times of the calculation of the Funds’ final net asset value for creation and redemption of fund Shares for the six months ended June 30, 2018 were as follows. All times are Eastern Standard Time:

* Although the Funds’ shares may continue to trade on secondary markets subsequent to the calculation of the final NAV, these times represent the final opportunity to transact in creation or redemption units for the six months ended June 30, 2018.

Market value per Share is determined at the close of the NYSE Arca and may be later than when the Funds’ NAV per Share is calculated.

For financial reporting purposes, the Funds value transactions based upon the final closing price in their primary markets. Accordingly, the investment valuations in these financial statements may differ from those used in the calculation of certain of the Funds’ final creation/redemption NAV for the six months ended June 30, 2018.

Investment Valuation

Short-term investments are valued at amortized cost which approximates fair value for daily NAV purposes. For financial reporting purposes, short-term investments are valued at their market price using information provided by a third-party pricing service or market quotations. In each of these situations, valuations are typically categorized as Level I in the fair value hierarchy.

Derivatives (e.g., futures contracts, swap agreements, forward agreements and foreign currency forward contracts) are typically valued using independent sources and/or agreements with counterparties or other procedures as determined by the Sponsor. Futures contracts, except for those entered into by the Gold, Silver, Australian Dollar and Short Euro Funds, are typically valued at the last settled price on the applicable exchange on which that future trades. Futures contracts entered into by the Gold, Silver, Australian Dollar and Short Euro Funds are typically valued at the last sales price prior to the time at which the NAV per Share of a Fund is determined. For financial reporting purposes, all futures contracts are typically valued at the last settled price. Futures contracts valuations are typically categorized as Level I in the fair value hierarchy. Swap agreements, forward agreements and foreign currency forward contracts valuations are typically categorized as Level II in the fair value hierarchy. The Sponsor may in its sole discretion choose to determine a fair value price as the basis for determining the market value of such position. Such fair value prices would generally be determined based on available inputs about the current value of the underlying financial instrument or commodity and would be based on principles that the Sponsor deems fair and equitable so long as such principles are consistent with industry standards. The Sponsor may fair value an asset of a Fund pursuant to the policies the Sponsor has adopted, which are consistent with normal industry standards. Depending on the source and relevant significance of valuation inputs, these instruments may be classified as Level II or Level III in the fair value hierarchy.

Fair value pricing may require subjective determinations about the value of an investment. While the Funds’ policies are intended to result in a calculation of its respective Fund’s NAV that fairly reflects investment values as of the time of pricing, such Fund cannot ensure that fair values determined by the Sponsor or persons acting at their direction would accurately reflect the price that a Fund could obtain for an investment if it were to dispose of that investment as of the time of pricing (for instance, in a forced or distressed sale). The prices used by such Fund may differ from the value that would be realized if the investments were sold and the differences could be material to the financial statements.

Fair Value of Financial Instruments

The Funds disclose the fair value of their investments in a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The disclosure requirements establish a fair value hierarchy that distinguishes between: (1) market participant assumptions developed based on market data obtained from sources independent of the Funds (observable inputs); and (2) the Funds’ own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the disclosure requirements hierarchy are as follows:

Level I – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

111

Level II – Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level II assets include the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs).

Level III – Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available.

In some instances, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest input level that is significant to the fair value measurement in its entirety.

Fair value measurements also require additional disclosure when the volume and level of activity for the asset or liability have significantly decreased, as well as when circumstances indicate that a transaction is not orderly.

The Funds’ policy is to recognize transfers between valuation levels at the end of the reporting period.

At June 30, 2018, there were no significant transfers in or out of Level I and Level II fair value measurements.

Investment Transactions and Related Income

Investment transactions are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized appreciation/depreciation on open contracts are reflected in the Statements of Financial Condition and changes in the unrealized appreciation/depreciation between periods are reflected in the Statements of Operations. Discounts on short-term securities purchased are amortized and reflected as Interest Income in the Statements of Operations.

Brokerage Commissions and Fees

Each Fund pays its respective brokerage commissions, including applicable exchange fees, National Futures Association (“NFA”) fees, give-up fees, pit brokerage fees and other transaction related fees and expenses charged in connection with trading activities for each Fund’s investment in U.S. Commodity Futures Trading Commission (“CFTC”) regulated investments. The effects of trading spreads, financing costs/fees associated with Financial Instruments, and costs relating to the purchase of U.S. Treasury securities or similar high credit quality short-term fixed-income would also be borne by the Funds. Brokerage commissions on futures contracts are recognized on a half-turn basis (e.g., the first half is recognized when the contract is purchased (opened) and the second half is recognized when the transaction is closed). The Sponsor is currently paying brokerage commissions on VIX futures contracts for the Matching VIX Funds that exceed variable create/redeem fees collected by more than 0.02% of the Matching VIX Fund’s average net assets annually.

Federal Income Tax

Each Fund is registered as a series of a Delaware statutory trust and is treated as a partnership for U.S. federal income tax purposes. Accordingly, no Fund expects to incur U.S. federal income tax liability; rather, each beneficial owner of a Fund’s Shares is required to take into account its allocable share of its Fund’s income, gain, loss, deductions and other items for its Fund’s taxable year ending with or within the beneficial owner’s taxable year.

Management of the Funds has reviewed all open tax years and major jurisdictions (i.e., the last four tax year ends and the interim tax period since then, as applicable) and concluded that there is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken in future tax returns. The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. On an ongoing basis, management will monitor its tax positions taken under the interpretation to determine if adjustments to conclusions are necessary based on factors including, but not limited to, on-going analysis of tax law, regulation, and interpretations thereof.

New Accounting Pronouncements

In November 2016, the FASB issued Accounting Standards Update No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash” (“ASU 2016-18”), which amends ASC 230 to provide guidance on the classification and presentation of changes in restricted cash and restricted cash equivalents on the statement of cash flows. The ASU has been adopted for the current reporting period under the retrospective transition method. The adoption had no significant impact to the Statement of Cash Flows.

NOTE 3 – INVESTMENTS

Short-Term Investments

The Funds may purchase U.S. Treasury Bills, agency securities, and other high-credit quality short-term fixed income or similar securities with original maturities of one year or less. A portion of these investments may be posted as collateral in connection with swap agreements, futures, and/or forward contracts.

114

Accounting for Derivative Instruments

In seeking to achieve each Fund’s investment objective, the Sponsor uses a mathematical approach to investing. Using this approach, the Sponsor determines the type, quantity and mix of investment positions, including derivative positions, which the Sponsor believes in combination, should produce returns consistent with a Fund’s objective.

All open derivative positions at period end are reflected on each respective Fund’s Schedule of Investments. Certain Funds utilized a varying level of derivative instruments in conjunction with investment securities in seeking to meet their investment objective during the period. While the volume of open positions may vary on a daily basis as each Fund transacts derivatives contracts in order to achieve the appropriate exposure to meet its investment objective, the volume of these open positions relative to the net assets of each respective Fund at the date of this report is generally representative of open positions throughout the reporting period.

As discussed in Note 1, the Short VIX Short-Term Futures ETF and the Ultra VIX Short-Term Futures ETF changed their investment objectives and target exposures as of the close of business on February 27, 2018. From this time through the effective end of the reporting period, the volume of the derivative exposure relative to the net assets was generally representative to their current investment objectives. From the beginning of the reporting period until the close of business on February 27, 2018, the volume of the derivative exposure relative to the net assets was generally representative to their previous investment objectives.

Following is a description of the derivative instruments used by the Funds during the reporting period, including the primary underlying risk exposures related to each instrument type.

Futures Contracts

The Funds may enter into futures contracts to gain exposure to changes in the value of, or as a substitute for investing directly in (or shorting), an underlying index, currency or commodity. A futures contract obligates the seller to deliver (and the purchaser to accept) the future delivery of a specified quantity and type of asset at a specified time and place. The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity, if applicable, or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery, or by cash settlement at expiration of contract.

Upon entering into a futures contract, each Fund is required to deposit and maintain as collateral at least such initial margin as required by the exchange on which the transaction is affected. The initial margin is segregated as cash and/or securities balances with brokers for futures contracts, as disclosed in the Statements of Financial Condition, and is restricted as to its use. The Funds that enter into futures contracts maintain collateral at the broker in the form of cash and/or securities. Pursuant to the futures contract, each Fund generally agrees to receive from or pay to the broker(s) an amount of cash equal to the daily fluctuation in value of the futures contract. Such receipts or payments are known as variation margin and are recorded by each Fund as unrealized gains or losses. Each Fund will realize a gain or loss upon closing of a futures transaction.

Futures contracts involve, to varying degrees, elements of market risk (specifically commodity price risk or equity market volatility risk) and exposure to loss in excess of the amount of variation margin. The face or contract amounts reflect the extent of the total exposure each Fund has in the particular classes of instruments. Additional risks associated with the use of futures contracts are imperfect correlation between movements in the price of the futures contracts and the market value of the underlying index or commodity and the possibility of an illiquid market for a futures contract. With futures contracts, there is minimal but some counterparty risk to the Funds since futures contracts are exchange-traded and the exchange’s clearinghouse, as counterparty to all exchange-traded futures contracts, guarantees the futures contracts against default. Many futures exchanges and boards of trade limit the amount of fluctuation permitted in futures contract prices during a single trading day. Once the daily limit has been reached in a particular contract, no trades may be made that day at a price beyond that limit or trading may be suspended for specified times during the trading day. Futures contracts prices could move to the limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and potentially subjecting a Fund to substantial losses. If trading is not possible, or if a Fund determines not to close a futures position in anticipation of adverse price movements, the Fund will be required to make daily cash payments of variation margin. The risk the Fund will be unable to close out a futures position will be minimized by entering into such transactions on a national exchange with an active and liquid secondary market.

115

Swap Agreements

Certain of the Funds enter into swap agreements for purposes of pursuing their investment objectives or as a substitute for investing directly in (or shorting) an underlying index, currency or commodity, or to create an economic hedge against a position. Swap agreements are two-party contracts that have traditionally been entered into primarily with institutional investors in over-the-counter (“OTC”) markets for a specified period, ranging from a day to more than one year. However, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) provides for significant reforms of the OTC derivative markets, including a requirement to execute certain swap transactions on a CFTC-regulated market and/or to clear such transactions through a CFTC-regulated central clearing organization. In a standard swap transaction, two parties agree to exchange the returns earned or realized on a particular predetermined investment, instrument or index in exchange for a fixed or floating rate of return in respect of a predetermined notional amount. Transaction or commission costs are reflected in the benchmark level at which the transaction is entered into. The gross returns to be exchanged are calculated with respect to a notional amount and the benchmark returns to which the swap is linked. Swap agreements do not involve the delivery of underlying instruments.

Generally, swap agreements entered into by the Funds calculate and settle the obligations of the parties to the agreement on a “net basis” with a single payment. Consequently, each Fund’s current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of such obligations (or rights) (the “net amount”). In a typical swap agreement entered into by a Matching VIX Fund, an Ultra Fund, or an UltraPro Fund, the Matching VIX Fund, Ultra Fund, or UltraPro Fund would be entitled to settlement payments in the event the level of the benchmark increases and would be required to make payments to the swap counterparties in the event the level of the benchmark decreases, adjusted for any transaction costs or trading spreads on the notional amount the Funds may pay. In a typical swap agreement entered into by a Short Fund, an UltraShort Fund, or an UltraPro Short Fund, the Short Fund, UlraShort Fund, or UltraPro Short Fund would be required to make payments to the swap counterparties in the event the level of the benchmark increases and would be entitled to settlement payments in the event the level of the benchmark decreases, adjusted for any transaction costs or trading spreads on the notional amount the Funds may pay.

The net amount of the excess, if any, of each Fund’s obligations over its entitlements with respect to each uncleared swap agreement is accrued on a daily basis and an amount of cash and/or securities having an aggregate value at least equal to such accrued excess is maintained for the benefit of the counterparty in a segregated account by the Funds’ Custodian. The net amount of the excess, if any, of each Fund’s entitlements over its obligations with respect to each uncleared swap agreement is accrued on a daily basis and an amount of cash and/or securities having an aggregate value at least equal to such accrued excess is maintained for the benefit of the Fund in a segregated account by the Fund’s Custodian. Until a swap agreement is settled in cash, the gain or loss on the notional amount less any transaction costs or trading spreads payable by each Fund on the notional amount are recorded as “unrealized appreciation or depreciation on swap agreements” and, when cash is exchanged, the gain or loss realized is recorded as “realized gains or losses on swap agreements.” Swap agreements are generally valued at the last settled price of the benchmark referenced asset.

Swap agreements contain various conditions, events of default, termination events, covenants and representations. The triggering of certain events or the default on certain terms of the agreement could allow a party to terminate a transaction under the agreement and request immediate payment in an amount equal to the net positions owed the party under the agreement. This could cause a Fund to have to enter into a new transaction with the same counterparty, enter in to a transaction with a different counterparty or seek to achieve its investment objective through any number of different investments or investment techniques.

Swap agreements involve, to varying degrees, elements of market risk and exposure to loss in excess of the unrealized gain/loss reflected. The notional amounts reflect the extent of the total investment exposure each Fund has under the swap agreement, which may exceed the NAV of each Fund. Additional risks associated with the use of swap agreements are imperfect correlations between movements in the notional amount and the price of the underlying reference index and the inability of counterparties to perform. Each Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. A Fund will typically enter into swap agreements only with major global financial institutions. The creditworthiness of each of the firms that is a party to a swap agreement is monitored by the Sponsor. The Sponsor may use various techniques to minimize credit risk including early termination and payment, using different counterparties, limiting the net amount due from any individual counterparty and generally requiring collateral to be posted by the counterparty in an amount approximately equal to that owed to the Funds. All of the outstanding swap agreements at June 30, 2018 contractually terminate within one month but may be terminated without penalty by either party daily. Upon termination, the Fund is entitled to pay or receive the “unrealized appreciation or depreciation” amount.

The Funds, as applicable, collateralize swap agreements by segregating or designating cash and/or certain securities as indicated on the Statements of Financial Condition or Schedules of Investments. As noted above, collateral posted in connection with uncleared derivative transactions is held for the benefit of the counterparty in a segregated tri-party account at the Custodian to protect the counterparty against non-payment by the Funds. The collateral held in this account is restricted as to its use. In the event of a default by the counterparty, the Funds will seek withdrawal of this collateral from the segregated account and may incur certain costs in exercising its right with respect to the collateral. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Funds may experience significant delays in obtaining any recovery in a bankruptcy or other reorganizational proceeding. The Funds may obtain only limited recovery or may obtain no recovery in such circumstances.

The Funds remain subject to credit risk with respect to the amount they expect to receive from counterparties. However, the Funds have sought to mitigate these risks in connection with uncleared swaps by generally requiring that the counterparties for each Fund agree to post collateral for the benefit of the Fund, marked to market daily, in an amount approximately equal to what the counterparty owes the Fund, subject to certain minimum thresholds. In the event of the bankruptcy of a counterparty, such Fund will have direct access to the collateral received from the counterparty, generally as of the day prior to the bankruptcy, because there is a one day time lag between the Fund’s request for collateral and the delivery of such collateral. To the extent any such collateral is insufficient, the Funds will be exposed to counterparty risk as described above, including the possible delays in recovering amounts as a result of bankruptcy proceedings. As of June 30, 2018, the collateral posted by counterparties consisted of cash and/or U.S. Treasury securities.

The counterparty/credit risk for cleared derivative transactions is generally lower than for uncleared OTC derivatives since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries.

Forward Contracts

Certain of the Funds enter into forward contracts for purposes of pursuing their investment objectives and as a substitute for investing directly in (or shorting) commodities and/or currencies. A forward contract is an agreement between two parties to purchase or sell a specified quantity of an asset at or before a specified date in the future at a specified price. Forward contracts are typically traded in OTC markets and all details of the contracts are negotiated between the counterparties to the agreement. Accordingly, the forward contracts are valued by reference to the contracts traded in the OTC markets.

The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or currency, establishing an opposite position in the contract and recognizing the profit or loss on both positions simultaneously on the delivery date or, in some instances, paying a cash settlement before the designated date of delivery. The forward contracts are adjusted by the daily fluctuation of the underlying commodity or currency and any gains or losses are recorded for financial statement purposes as unrealized gains or losses until the contract settlement date.

Forward contracts have traditionally not been cleared or guaranteed by a third party. As a result of the Dodd-Frank Act, the CFTC now regulates non-deliverable forwards (including deliverable forwards where the parties do not take delivery). Certain non-deliverable forward contracts, such as non-deliverable foreign exchange forwards, may be subject to regulation as swap agreements, including mandatory clearing. Changes in the forward markets may entail increased costs and result in burdensome reporting requirements.

The Funds may collateralize uncleared forward commodity contracts by segregating or designating cash and/or certain securities as indicated on their Statements of Financial Condition or Schedules of Investments. Such collateral is held for the benefit of the counterparty in a segregated tri-party account at the Custodian to protect the counterparty against non-payment by the Funds. The collateral held in this account is restricted as to its use. In the event of a default by the counterparty, the Funds will seek withdrawal of this collateral from the segregated account and may incur certain costs in exercising its right with respect to the collateral. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Funds may experience significant delays in obtaining any recovery in a bankruptcy or other reorganizational proceeding. The Funds may obtain only limited recovery or may obtain no recovery in such circumstances.

As of June 30, 2018, the collateral posted by counterparties consisted of cash and/or U.S. Treasury securities.

Participants in trading foreign exchange forward contracts often do not require margin deposits, but rely upon internal credit limitations and their judgments regarding the creditworthiness of their counterparties. In recent years, however, many OTC market participants in foreign exchange trading have begun to require their counterparties to post margin.

A Fund will typically enter into forward contracts only with major global financial institutions. The creditworthiness of each of the firms that is a party to a forward contract is monitored by the Sponsor.

The counterparty/credit risk for cleared derivative transactions is generally lower than for uncleared OTC derivatives since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries.

Offsetting Assets and Liabilities

Each Fund is subject to master netting agreements or similar arrangements that allow for amounts owed between each Fund and the counterparty to be netted upon an early termination. The party that has the larger payable pays the excess of the larger amount over the smaller amount to the other party. The master netting agreements or similar arrangements do not apply to amounts owed to/from different counterparties. As described above, the Funds utilize derivative instruments to achieve their investment objective during the year. The amounts shown in the Statements of Financial Condition do not take into consideration the effects of legally enforceable master netting agreements or similar arrangements.

For financial reporting purposes, the Funds do not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statements of Financial Condition. The following table presents each Fund’s derivatives by investment type and by counterparty net of amounts available for offset under a master netting agreement and the related collateral received or pledged by the Funds as of June 30, 2018.

Asset (Liability) amounts shown in the table below represent amounts owed to (by) the Funds for the derivative-related investments at June 30, 2018. These amounts may be collateralized by cash or financial instruments, segregated for the benefit of the Funds or the counterparties, depending on whether the related contracts are in an appreciated or depreciated position at period end. Amounts shown in the column labeled “Net Amount” represent the uncollateralized portions of these amounts at period end. These amounts may be un-collateralized due to timing differences related to market movements or due to minimum thresholds for collateral movement, as further described above under the caption “Accounting for Derivative Instruments”.

Asset (Liability) amounts shown in the table below represent amounts owed to (by) the Funds for the derivative-related investments at December 31, 2017. These amounts may be collateralized by cash or financial instruments, segregated for the benefit of the Funds or the counterparties, depending on whether the related contracts are in an appreciated or depreciated position at period end. Amounts shown in the column labeled “Net Amount” represent the uncollateralized portions of these amounts at period end. These amounts may be un-collateralized due to timing differences related to market movements or due to minimum thresholds for collateral movement, as further described above under the caption “Accounting for Derivative Instruments”.

NOTE 4 – AGREEMENTS

Management Fee

Each Leveraged Fund, the Short Euro Fund and each Geared VIX Fund pays the Sponsor a Management Fee, monthly in arrears, in an amount equal to 0.95% per annum of its average daily NAV of such Fund. Each Matching VIX Fund pays the Sponsor a Management Fee, monthly in arrears, in an amount equal to 0.85% per annum of its average daily NAV of such Fund. The Sponsor has not and will not charge a Management Fee in each of the Fund’s first year of operations in an amount equal to the offering costs. The Sponsor has reimbursed and will reimburse each Fund, to the extent that its offering costs exceed the Management Fee, for the first year of operations.

The Management Fee is paid in consideration of the Sponsor’s trading advisory services and the other services provided to the Fund that the Sponsor pays directly. From the Management Fee, the Sponsor pays all of the routine operational, administrative and other ordinary expenses of each Fund, generally as determined by the Sponsor, including but not limited to the Administrator, Custodian, Distributor, ProFunds Distributors, Inc. (“PDI”), an affiliated broker-dealer of the Sponsor, Transfer Agent, accounting and auditing fees and expenses, any index licensors for the Funds, and the normal and expected expenses incurred in connection with the continuous offering of Shares of each Fund after the commencement of its trading operations, including, but not limited to, expenses such as tax preparation expenses, legal fees not in excess of $100,000 per annum, ongoing SEC registration fees not exceeding 0.021% per annum of the NAV of a Fund and Financial Industry Regulatory Authority (“FINRA”) filing fees, individual ScheduleK-1 preparation and mailing fees not exceeding 0.10% per annum of the net assets of a Fund, and report preparation and mailing expenses.

Non-Recurring Fees and Expenses

Each Fund pays all its non-recurring and unusual fees and expenses, if any, as determined by the Sponsor. Non-recurring and unusual fees and expenses are fees and expenses that are unexpected or unusual in nature, such as legal claims and liabilities, litigation costs or indemnification or other material expenses which are not currently anticipated obligations of the Funds.

The Administrator

The Sponsor and the Trust, for itself and on behalf of each Fund, has appointed Brown Brothers Harriman & Co. (“BBH&Co.”) as the Administrator of the Funds, and the Sponsor, and the Trust, on its own behalf and on behalf of each Fund, and BBH&Co. have entered into an Administrative Agency Agreement (the “Administration Agreement”) in connection therewith. Pursuant to the terms of the Administration Agreement and under the supervision and direction of the Sponsor and the Trust, BBH&Co. prepares and files certain regulatory filings on behalf of the Funds. BBH&Co. may also perform other services for the Funds pursuant to the Administration Agreement as mutually agreed upon by the Sponsor, the Trust and BBH&Co. from time to time. Pursuant to the terms of the Administration Agreement, BBH&Co. also serves as the Transfer Agent of the Funds. The Administrator’s fees are paid on behalf of the Funds by the Sponsor.

The Custodian

BBH&Co. serves as the Custodian of the Funds, and the Trust, on its own behalf and on behalf of each Fund, and BBH&Co. have entered into a Custodian Agreement in connection therewith. Pursuant to the terms of the Custodian Agreement, BBH&Co. is responsible for the holding and safekeeping of assets delivered to it by the Funds, and performing various administrative duties in accordance with instructions delivered to BBH&Co. by the Funds. The Custodian’s fees are paid on behalf of the Funds by the Sponsor.

129

The Distributor

SEI Investments Distribution Co. (“SEI”), serves as Distributor of the Funds and assists the Sponsor and the Administrator with certain functions and duties relating to distribution and marketing, including taking creation and redemption orders, consulting with the marketing staff of the Sponsor and its affiliates with respect to compliance with the requirements of FINRA and/or the NFA in connection with marketing efforts, and reviewing and filing of marketing materials with FINRA and/or the NFA. SEI retains all marketing materials separately for each Fund, at c/o SEI, One Freedom Valley Drive, Oaks, PA 19456. The Sponsor, on behalf of each Fund, has entered into a Distribution Services Agreement with SEI. The Sponsor pays SEI for performing its duties on behalf of the Funds.

NOTE 5 – OFFERING COSTS

Offering costs will be amortized by the Funds over a twelve month period on a straight-line basis beginning once the fund commences operations. The Sponsor will not charge its Management Fee in the first year of operations of a Fund in an amount equal to the offering costs. Normal and expected expenses incurred in connection with the continuous offering of Shares of a Fund after the commencement of its trading operations will be paid by the Sponsor. The Sponsor has reimbursed ProShares UltraPro 3x Crude Oil ETF and ProShares UltraPro 3x Short Crude Oil ETF to the extent that their respective offering costs exceeded 0.95% of their average daily NAV during their first year of operations.

NOTE 6 – CREATION AND REDEMPTION OF CREATION UNITS

Each Fund issues and redeems shares from time to time, but only in one or more Creation Units. A Creation Unit is a block of 50,000 Shares of a Geared Fund and 25,000 Shares of a Matching VIX Fund. Creation Units may be created or redeemed only by Authorized Participants. As a result of the Share splits and reverse Share splits as described in Note 1, certain redemptions as disclosed in the Statements of Changes in Shareholders’ Equity reflect payment of fractional share balances on beneficial shareholder accounts.

Except when aggregated in Creation Units, the Shares are not redeemable securities. Retail investors, therefore, generally will not be able to purchase or redeem Shares directly from or with a Fund. Rather, most retail investors will purchase or sell Shares in the secondary market with the assistance of a broker. Thus, some of the information contained in these Notes to Financial Statements—such as references to the Transaction Fees imposed on purchases and redemptions is not relevant to retail investors.

Transaction Fees on Creation and Redemption Transactions

The manner by which Creation Units are purchased or redeemed is governed by the terms of the Authorized Participant Agreement and Authorized Participant Handbook. By placing a purchase order, an Authorized Participant agrees to: (1) deposit cash with the Custodian; and (2) if permitted by the Sponsor in its sole discretion, enter into or arrange for an exchange of futures contract for related position or block trade with the relevant fund whereby the Authorized Participant would also transfer to such Fund a number and type of exchange-traded futures contracts at or near the closing settlement price for such contracts on the purchase order date.

Authorized Participants may pay a fixed transaction fee of up to $250 in connection with each order to create or redeem a Creation Unit in order to compensate BBH&Co., as the Administrator, the Custodian and the Transfer Agent of each Fund and its Shares, for services in processing the creation and redemption of Creation Units and to offset the costs of increasing or decreasing derivative positions. Authorized Participants also may pay a variable transaction fee to the Fund of up to 0.10% (and a variable transaction fee to the Matching VIX Funds of 0.05%) of the value of the Creation Unit that is purchased or redeemed unless the transaction fee is waived or otherwise adjusted by the Sponsor. The Sponsor provides such Authorized Participant with prompt notice in advance of any such waiver or adjustment of the transaction fee. Authorized Participants may sell the Shares included in the Creation Units they purchase from the Funds to other investors in the secondary market.

NOTE 8 – RISK

Correlation and Compounding Risk

The Geared Funds do not seek to achieve their stated investment objective over a period of time greater than a single day (as measured from NAV calculation time to NAV calculation time). The return of a Geared Fund for a period longer than a single day is the result of its return for each day compounded over the period and usually will differ from the one-half inverse (-0.5x), the inverse (-1x), two times the inverse (-2x), one and one-half times (1.5x) of the return, two times (2x) of the return, three times the inverse (-3x), or three times of the return (3x) of the Geared Fund’s benchmark for the period. A Geared Fund will lose money if its benchmark performance is flat over time, and it is possible for a Geared Fund to lose money over time even if the performance of its benchmark increases (or decreases in the case of Short, UltraShort and UltraPro Short Funds), as a result of daily rebalancing, the benchmark’s volatility, compounding, and other factors. Longer holding periods, higher benchmark volatility, inverse exposure and greater leverage each affect the impact of compounding on a Geared Fund’s returns. Daily compounding of a Geared Fund’s investment returns can dramatically and adversely affect its longer-term performance during periods of high volatility. Volatility may be at least as important to a Geared Fund’s return fora period as the return of the Geared Fund’s underlying benchmark. The Matching VIX Funds seek to achieve their stated investment objective over time.

Each Ultra, UltraShort, UltraPro and UltraPro Short Fund uses leverage and should produce daily returns that are more volatile than that of its benchmark. For example, the daily return of an Ultra or UltraPro Fund with a 1.5x or 2x or 3x multiple should be approximately one and one-half or two or three times as volatile on a daily basis as is the return of a fund with an objective of matching the same benchmark. The daily return of an UltraShort or UltraPro Short Fund is designed to return two times the inverse (-2x) or three times the inverse (-3x) of the return that would be expected of a fund with an objective of matching the same benchmark. The Geared Funds are not appropriate for all investors and present significant risks not applicable to other types funds. The Leveraged Funds use leverage and are riskier than similarly benchmarked exchange-traded funds that do not use leverage. An investor should only consider an investment in a Geared Fund if he or she understands the consequences of seeking daily leveraged, daily inverse or daily inverse leveraged investment results. Shareholders who invest in the Funds should actively manage and monitor their investments, as frequently as daily.

While the Funds seek to meet their investment objectives, there is no guarantee they will do so. Factors that may affect a Fund’s ability to meet its investment objective include: (1) the Sponsor’s ability to purchase and sell Financial Instruments in a manner that correlates to a Fund’s objective; (2) an imperfect correlation between the performance of Financial Instruments held by a Fund and the performance of the applicable benchmark; (3) bid-ask spreads on such Financial Instruments; (4) fees, expenses, transaction costs, financing costs associated with the use of Financial Instruments and commission costs; (5) holding or trading instruments in a market that has become illiquid or disrupted; (6) a Fund’s Share prices being rounded to the nearest cent and/or valuation methodology; (7) changes to a benchmark index that are not disseminated in advance; (8) the need to conform a Fund’s portfolio holdings to comply with investment restrictions or policies or regulatory or tax law requirements; (9) early and unanticipated closings of the markets on which the holdings of a Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions; (10) accounting standards; and (11) differences caused by a Fund obtaining exposure to only a representative sample of the components of a benchmark, over weighting or under weighting certain components of a benchmark or obtaining exposure to assets that are not included in a benchmark.

A number of factors may affect a Geared Fund’s ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that a Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent a Geared Fund from achieving its investment objective. In order to achieve a high degree of correlation with their underlying benchmarks, the Geared Funds seek to rebalance their portfolios daily to keep exposure consistent with their investment objectives. Being materially under- or over-exposed to the benchmark may prevent such Geared Funds from achieving a high degree of correlation with such benchmark. Market disruptions or closure, large amounts of assets into or out of the Geared Funds, regulatory restrictions, extreme market volatility, and other factors will adversely affect such Funds’ ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by the benchmarks’ movements during each day. Because of this, it is unlikely that the Geared Funds will be perfectly exposed (i.e., -0.5x, -1x, -2x, 1.5x, 2x, -3x or 3x as applicable) to its benchmark at the end of each day, and the likelihood of being materially under- or over-exposed is higher on days when the benchmark levels are volatile near the close of the trading day.

148

Each Geared Fund seeks to rebalance its portfolio on a daily basis. The time and manner in which a Geared Fund rebalances its portfolio may vary from day to day depending upon market conditions and other circumstances at the discretion of the Sponsor. Unlike other funds that do not rebalance their portfolios as frequently, each Geared Fund may be subject to increased trading costs associated with daily portfolio rebalancing in order to maintain appropriate exposure to the underlying benchmarks.

Counterparty Risk

Each Fund may use derivatives such as swap agreements and forward contracts (collectively referred to herein as “derivatives”) in the manner described herein as a means to achieve their respective investment objectives. The use of derivatives by a Fund exposes the Fund to counterparty risks.

Regulatory Treatment

Derivatives are generally traded in over-the-counter (“OTC”) markets and have only recently become subject to comprehensive regulation in the United States. Cash-settled forwards are generally regulated as “swaps”, whereas physically settled forwards are generally not subject to regulation (in the case of commodities other than currencies) or subject to the federal securities laws (in the case of securities).

Title VII of the Dodd-Frank Act (“Title VII”) created a regulatory regime for derivatives, with the CFTC responsible for the regulation of swaps and the SEC responsible for the regulation of “security-based swaps.” The SEC requirements have largely yet to be made effective, but the CFTC requirements are largely in place. The CFTC requirements have included rules for some of the types of transactions in which the Funds will engage, including mandatory clearing and exchange trading, reporting, and margin for uncleared swaps. Title VII also created new categories of regulated market participants, such as “swap dealers,” “security-based swap dealers,” “major swap participants,” and “major security-based swap participants” who are, or will be, subject to significant new capital,

registration, recordkeeping, reporting, disclosure, business conduct and other regulatory requirements. The regulatory requirements under Title VII continue to be developed and there may be further modifications that could impact the Funds.

As noted, the CFTC rules may not apply to all of the swap agreements and forward contracts entered into by the Funds. Investors, therefore, may not receive the protection of CFTC regulation or the statutory scheme of the CEA in connection with each Fund’s swap agreements or forward contracts. The lack of regulation in these markets could expose investors to significant losses under certain circumstances, including in the event of trading abuses or financial failure by participants.

Counterparty Credit Risk

The Funds will be subject to the credit risk of the counterparties to the derivatives. In the case of cleared derivatives, the Funds will have credit risk to the clearing corporation in a similar manner as the Funds would for futures contracts. In the case of uncleared derivatives, the Funds will be subject to the credit risk of the counterparty to the transaction – typically a single bank or financial institution. As a result, a Fund is subject to increased credit risk with respect to the amount it expects to receive from counterparties to uncleared derivatives entered into as part of that Fund’s principal investment strategy. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, a Fund could suffer significant losses on these contracts and the value of an

investor’s investment in a Fund may decline.

The Funds have sought to mitigate these risks by generally requiring that the counterparties for each Fund agree to post collateral for the benefit of the Fund, marked to market daily, subject to certain minimum thresholds. However, there are no limitations on the percentage of assets each Fund may invest in swap agreements or forward contracts with a particular counterparty. To the extent any such collateral is insufficient or there are delays in accessing the collateral, the Funds will be exposed to counterparty risk as described above, including possible delays in recovering amounts as a result of bankruptcy proceedings. The Funds typically enter into transactions only with major, global financial institutions.

149

OTC derivatives of the type that may be utilized by the Funds are generally less liquid than futures contracts because they are not traded on an exchange, do not have uniform terms and conditions, and are generally entered into based upon the creditworthiness of the parties and the availability of credit support, such as collateral, and in general, are not transferable without the consent of the counterparty. These agreements contain various conditions, events of default, termination events, covenants and representations. The triggering of certain events or the default on certain terms of the agreement could allow a party to terminate a transaction under the agreement and request immediate payment in an amount equal to the net positions owed to the party under the agreement. For example, if the level of the Fund’s benchmark has a dramatic intraday move that would cause a material decline in the Fund’s NAV, the terms of the swap may permit the counterparty to immediately close out the transaction with the Fund. In that event, it may not be possible for the Fund to enter into another swap or to invest in other Financial Instruments necessary to achieve the desired exposure consistent with the Fund’s objective. This, in turn, may prevent the Fund from achieving its investment objective, particularly if the level of the Fund’s benchmark reverses all or part of its intraday move by the end of the day.

In addition, cleared derivatives benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. To the extent the Fund enters into cleared swap transactions, the Fund will deposit collateral with an FCM in cleared swaps customer accounts, which are required by CFTC regulations to be separate from its proprietary collateral posted for cleared swaps transactions. Cleared swap customer collateral is subject to regulations that closely parallel the regulations governing customer segregated funds for futures transactions but provide certain additional protections to cleared swaps collateral in the event of a clearing broker or clearing broker customer default. For example, in the event of a default of both the clearing broker and a customer of the clearing broker, a clearing house is only permitted to access the cleared swaps collateral in the legally separate (but operationally comingled) account of the defaulting cleared swap customer of the clearing broker, as opposed to the treatment of customer segregated funds, under which the clearing house may access all of the commingled customer segregated funds of a defaulting clearing broker. Uncleared derivatives entered into directly between two counterparties do not necessarily benefit from such protections, particularly if entered into with an entity that is not registered as a “swap dealer” with the CFTC. This exposes the Funds to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Funds to suffer a loss.

150

The Sponsor regularly reviews the performance of its counterparties for, among other things, creditworthiness and execution quality. In addition, the Sponsor periodically considers the addition of new counterparties and the counterparties used by a Fund may change at any time. Each day, the Funds disclose their portfolio holdings as of the prior Business Day. Each Fund’s portfolio holdings identifies its counterparties, as applicable. This portfolio holdings information may be accessed through the web on the Sponsor’s website at www.ProShares.com.

Each counterparty and/or any of its affiliates may be an Authorized Participant or shareholder of a Fund, subject to applicable law.

The counterparty risk for cleared derivatives transactions is generally lower than for uncleared OTC derivatives. Once a transaction is cleared, the clearing organization is substituted and is a Fund’s counterparty on the derivative. The clearing organization guarantees the performance of the other side of the derivative. Nevertheless, some risk remains, as there is no assurance that the clearing organization, or its members, will satisfy its obligations to a Fund.

Leverage Risk

The Leveraged Funds may utilize leverage in seeking to achieve their respective investment objectives and will lose more money in market environments adverse to their respective daily investment objectives than funds that do not employ leverage. The use of leveraged and/or inverse leveraged positions could result in the total loss of an investor’s investment, even over periods as short as a single day.

For example, because the UltraShort Funds and Ultra Funds (except for the Ultra VIX Short-Term Futures ETF which includes a one and one-half times multiplier) include a two times the inverse (-2x), or a two times (2x) multiplier, a single-day movement in the relevant benchmark approaching 50% at any point in the day could result in the total loss or almost total loss of an investor’s investment if that movement is contrary to the investment objective of the Fund in which an investor has invested, even if such Fund’s benchmark subsequently moves in an opposite direction, eliminating all or a portion of the movement. For UltraPro Fund and UltraPro Short Fund, because the Funds include a three times (3x) or three times the inverse (-3x) multiplier, a single day movement in the benchmark approaching 33% at any point in the day could result in the total loss or almost total loss of an investor’s investment if that movement is contrary to the investment objective of the Fund in which an investor has invested, even if the benchmark subsequently moves in an opposite direction, eliminating all or a portion of the movement. This would be the case with downward single-day or intraday movements in the underlying benchmark of an Ultra Fund and UltraPro Fund or upward single-day or intraday movements in the benchmark of an UltraShort Fund and UltraPro Short Fund, even if the underlying benchmark maintains a level greater than zero at all times.

Liquidity Risk

Financial Instruments cannot always be liquidated at the desired price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A market disruption can also make it difficult to liquidate a position or find a swap or forward contract counterparty at a reasonable cost. Market illiquidity may cause losses for the Funds. The large size of the positions which the Funds may acquire increases the risk of illiquidity by both making their positions more difficult to liquidate and increasing the losses incurred while trying to do so. Any type of disruption or illiquidity will potentially be exacerbated due to the fact that the Funds will typically invest in Financial Instruments related to one benchmark, which in many cases is highly concentrated.

“Contango” and “Backwardation” Risk

In Funds that hold futures contracts, as the futures contracts near expiration, they are generally replaced by contracts that have a later expiration. Thus, for example, a contract purchased and held in November 2017 may specify a January 2018 expiration. As that contract nears expiration, it may be replaced by selling the January 2018 contract and purchasing the contract expiring in March 2018. This process is referred to as “rolling.” Rolling may have a positive or negative impact on performance. For example, historically, the prices of certain types of futures contracts have frequently been higher for contracts with shorter-term expirations than for contracts with longer-term expirations, which is referred to as “backwardation.” In these circumstances, absent other factors, the sale of the January

151

2018 contract would take place at a price that is higher than the price at which the March 2018 contract is purchased, thereby creating a gain in connection with rolling. While certain types of futures contracts have historically exhibited consistent periods of backwardation, backwardation will likely not exist in these markets at all times. The presence of contango (where prices of contracts are higher in the distant delivery months than in the nearer delivery months due to the costs of long-term storage of a physical commodity prior to delivery or other factors) in certain futures contracts at the time of rolling would be expected to adversely affect an Ultra Fund, an UltraPro Fund or a Matching VIX Fund that invests in such futures, and positively affect a Short Fund, an UltraShort Fund or an UltraPro Short Fund that invests in such futures. Similarly, the presence of backwardation in certain futures contracts at the time of rolling such contracts would be expected to adversely affect the Short Funds, UltraShort Funds, and UltraPro Short Funds, and positively affect the Ultra Funds, UltraPro Funds and Matching VIX Funds.

Since the introduction of VIX futures contracts, there have frequently been periods where VIX futures prices reflect higher expected volatility levels further out in time. This can result in a loss from “rolling” the VIX futures to maintain the constant weighted average maturity of the applicable VIX Futures Index. Losses from exchanging a lower priced VIX future for a higher priced longer-term future in the rolling process would adversely affect the value of each VIX Futures Index and, accordingly, decrease the return of the Ultra VIX Short-Term Futures ETF and the Matching VIX Funds.

Gold and silver have historically exhibited persistent “contango” markets rather than backwardation. Natural gas, like crude oil, moves in and out of backwardation and contango but historically has been in contango most commonly.

Introduction

ProShares Trust II (the “Trust”) is a Delaware statutory trust formed on October 9, 2007 and is currently organized into separate series (each, a “Fund” and collectively, the “Funds”). As of June 30, 2018, the following twenty series of the Trust have commenced investment operations: (i) ProShares VIX Short-Term Futures ETF and ProShares VIX Mid-Term Futures ETF (each, a “Matching VIX Fund” and collectively, the “Matching VIX Funds”); (ii) ProShares Short VIX Short-Term Futures ETF and ProShares Ultra VIX Short-Term Futures ETF (each, a “Geared VIX Fund” and collectively, the “Geared VIX Funds”); (iii) ProShares UltraShort Bloomberg Crude Oil, ProShares UltraPro 3x Short Crude Oil ETF, ProShares UltraShort Bloomberg Natural Gas, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Australian Dollar, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Crude Oil, ProShares UltraPro 3x Crude Oil ETF, ProShares Ultra Bloomberg Natural Gas, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen (each, a “Leveraged Fund” and collectively, the “Leveraged Funds”); and (iv) ProShares Short Euro (the “Short Euro Fund”). Each of the Funds listed above issues common units of beneficial interest (“Shares”), which represent units of fractional undivided beneficial interest in and ownership of only that Fund. The Shares of each Fund are listed on the New York Stock Exchange Archipelago (“NYSE Arca”). The Leveraged Funds, the Short Euro Fund and the Geared VIX Funds, are collectively referred to as the “Geared Funds” in this Quarterly Report on Form 10-Q. The Geared VIX Funds and the Matching VIX Funds are collectively referred to as the “VIX Funds” in this Quarterly Report on Form 10-Q.

The Trust had no operations prior to November 24, 2008, other than matters relating to its organization, the registration of each series under the Securities Act of 1933, as amended, and the sale and issuance to ProShare Capital Management LLC (the “Sponsor”) of fourteen Shares at an aggregate purchase price of $350 in each of the following Funds: ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Crude Oil, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen.

The Sponsor also serves as the Trust’s commodity pool operator. Wilmington Trust Company serves as the Trustee of the Trust (the “Trustee”). The Funds are commodity pools, as defined under the CEA and the applicable regulations of the Commodity Futures Trading Commission (the “CFTC”) and are operated by the Sponsor, a commodity pool operator registered with the CFTC. The Trust is not an investment company registered under the Investment Company Act of 1940, as amended.

Groups of Funds are collectively referred to in this Quarterly Report on Form 10-Q in several different ways. References to “Short Funds,” “UltraShort Funds,” “UltraPro Short Funds,” “Ultra Funds,” or “UltraPro Funds” refer to the different Funds based upon their investment objectives, but without distinguishing among the Funds’ benchmarks. References to “Commodity Index Funds”, “Commodity Funds” and “Currency Funds” refer to the different Funds according to their general benchmark categories without distinguishing among the Funds’ investment objectives or Fund-specific benchmarks. References to “VIX Funds” refer to the different Funds based upon their investment objective and their general benchmark categories.

Effective as of close of business on February 27, 2018, the investment objective of ProShares Ultra VIX Short-Term Futures ETF and ProShares Short VIX Short-Term Futures ETF changed.

153

ProShares Ultra VIX Short-Term Futures ETF changed its investment objective to seek daily investment results, before fees and expenses, that correspond to one and one-half times (1.5x) of the performance of the S&P 500 VIX Short-Term Futures Index for a single day. Prior to the close of business on February 27, 2018, the Fund’s investment objective was to seek results, before fees and expenses, that correspond to two times (2x) the performance of the Index for a single day.

ProShares Short VIX Short-Term Futures ETF changed its investment objective to seek daily investment results, before fees and expenses, that correspond to one-half the inverse (-0.5x) of the performance of the S&P 500 VIX Short-Term Futures Index for a single day. Prior to the close of business on February 27, 2018, the Fund’s investment objective was to seek results, before fees and expenses, that correspond to the inverse (-1x) of the Index for a single day.

As described in the prospectus for each Fund, each of the Funds intends to invest in financial instruments “Financial Instruments” (Financial Instruments are instruments whose value is derived from the value of an underlying asset, rate or benchmark including futures contracts, swap agreements, forward contracts and other instruments) as a substitute for investing directly in commodities, currencies, or spot volatility products in order to gain exposure to the VIX Index, natural gas, crude oil, precious metals, or currencies, as applicable. Financial Instruments also are used to produce economically “inverse,” “inverse leveraged” or “leveraged” investment results for the Geared Funds.

Each “Short” Fund seeks daily investment results, before fees and expenses, that correspond to either one-half inverse (-0.5x) or inverse (-1x) of the daily performance of its corresponding benchmark. Each “UltraShort” Fund seeks daily investment results, before fees and expenses, that correspond to two times the inverse (-2x) of the daily performance of its corresponding benchmark. Each “UltraPro Short” Fund seeks daily investment results, before fees and expenses, that correspond to three times the inverse (-3x) of the daily performance of its corresponding benchmark. Each “Ultra” Fund seeks daily investment results, before fees and expenses, that correspond to either one and one-half times (1.5x) or to two times (2x) the daily performance of its corresponding benchmark. Each “UltraPro” Fund seeks daily investment results, before fees and expenses, that correspond to three times (3x) of the daily performance of its corresponding benchmark. Each Matching VIX Fund seeks investment results, before fees and expenses, both over a single day and over time, that match the performance of its corresponding benchmark. Daily performance is measured from the calculation of one NAV to the next.

Each Geared Fund seeks investment results for a single day only, not for any other period. A “single day” is measured from the time a Fund calculates its respective net asset value per Share (“NAV”) to the time of the Fund’s next NAV calculation. This is different from most exchange-traded funds and means that the return of such Fund for a period longer than a single trading day will be the result of each day’s returns compounded over the period, which will very likely differ from -0.5x, -1x, -2x, 1.5x, 2x, -3x or 3x of the return of the benchmark to which such Fund is benchmarked for that period. In periods of higher market volatility, the volatility of the benchmark may be at least as important to a Geared Fund’s return for the period as the return of the benchmark. Geared Funds, that use leverage, are riskier than similarly benchmarked exchange-traded funds that do not use leverage. Accordingly, these Funds may not be suitable for all investors and should be used only by knowledgeable investors who understand the potential consequences of seeking daily leveraged, inverse or inverse leveraged investment results. Shareholders who invest in the Geared Funds should actively manage and monitor their investments, as frequently as daily.

Each Matching VIX Fund seeks results, before fees and expenses, that match the performance of the S&P 500 VIX Short-Term Futures Index (the “Short-Term VIX Index”) or the S&P 500 VIX Mid-Term Futures Index (the “Mid-Term VIX Index”) (each a “VIX Futures Index”). Each Geared VIX Fund seeks daily investment results, before fees and expenses, that correspond to a multiple or the inverse of the daily performance of the Short-Term VIX Index. Each VIX Fund intends to obtain exposure to its benchmark by investing primarily in futures contracts (“VIX futures contracts”) based on the Chicago Board Options Exchange (“CBOE”) Volatility Index (the “VIX”).

ProShares UltraShort Bloomberg Crude Oil, ProShares UltraPro 3x Short Crude Oil ETF, ProShares UltraShort Bloomberg Natural Gas, ProShares Ultra Bloomberg Crude Oil, ProShares UltraPro 3x Crude Oil ETF, and ProShares Ultra Bloomberg Natural Gas are benchmarked to indices designed to track the performance of commodity futures contracts, as applicable. The daily performance of these indexes and the corresponding Funds will likely be very different from the daily performance of the price of the related physical commodities.

154

Each Geared Fund continuously offers and redeems its Shares in blocks of 50,000 Shares and each Matching VIX Fund continuously offers and redeems its Shares in blocks of 25,000 Shares (each such block a “Creation Unit”). Only Authorized Participants may purchase and redeem Shares from a Fund and then only in Creation Units. An Authorized Participant is an entity that has entered into an Authorized Participant Agreement with one or more of the Funds. Shares of the Funds are offered to Authorized Participants in Creation Units at each Fund’s respective NAV. Authorized Participants may then offer to the public, from time to time, Shares from any Creation Unit they create at a per-Share market price that varies depending on, among other factors, the trading price of the Shares of each Fund on the NYSE Arca, the NAV and the supply of and demand for the Shares at the time of the offer. Shares from the same Creation Unit may be offered at different times and may have different offering prices based upon the above factors. The form of Authorized Participant Agreement and related Authorized Participant Handbook set forth the terms and conditions under which an Authorized Participant may purchase or redeem a Creation Unit. Authorized Participants do not receive from any Fund, the Sponsor, or any of their affiliates, any underwriting fees or compensation in connection with their sale of Shares to the public.

Liquidity and Capital Resources

In order to collateralize derivatives positions in indices, commodities or currencies, a portion of the NAV of each Fund is held in cash and/or U.S. Treasury securities, agency securities, or other high credit quality short term fixed-income or similar securities (such as shares of money market funds, bank deposits, bank money market accounts, certain variable rate-demand notes and repurchase agreements collateralized by government securities, whether denominated in U.S. dollars or the applicable foreign currency with respect to a Currency Fund). A portion of these investments may be posted as collateral in connection with swap agreements, futures, and/or forward contracts. The percentage that U.S. Treasury bills and other short-term fixed-income securities bear to the shareholders’ equity of each Fund varies from period to period as the market values of the underlying swaps, futures contracts and forward contracts change. During the three and six months ended June 30, 2018 and 2017, each of the Funds earned interest income as follows:

Each Fund’s underlying swaps, futures, forward contracts and foreign currency forward contracts, as applicable, may be subject to periods of illiquidity because of market conditions, regulatory considerations and other reasons. For example, swaps and forward contracts are not traded on an exchange, do not have uniform terms and conditions, and in general are not transferable without the consent of the counterparty. In the case of futures contracts, commodity exchanges may limit fluctuations in certain futures contract prices during a single day by regulations referred to as “daily limits.” During a single day, no futures trades may be executed at prices beyond the daily limit. Once the price of a futures contract has increased or decreased by an amount equal to the daily limit, positions in such futures contracts can neither be taken nor liquidated unless the traders are willing to effect trades at or within the limit. Futures contract prices have occasionally moved to the daily limit for several consecutive days with little or no trading. Such market conditions could prevent a Fund from promptly liquidating its futures positions.

Entry into swap agreements or forward contracts may further impact liquidity because these contractual agreements are executed “off-exchange” between private parties and, therefore, the time required to offset or “unwind” these positions may be greater than that for exchange-traded instruments. This potential delay could be exacerbated to the extent a counterparty is not a United States person.

The large size of the positions in which a Fund may acquire increases the risk of illiquidity by both making their positions more difficult to liquidate and increasing the losses incurred while trying to do so. Any type of disruption or illiquidity will potentially be exacerbated due to the fact that the Funds will typically invest in Financial Investments related to one benchmark, which in many cases is highly concentrated.

Because each Fund may enter into swaps and may trade futures and forward contracts, its capital is at risk due to changes in the value of these contracts (market risk) or the inability of counterparties to perform under the terms of the contracts (credit risk).

Market Risk

Trading in derivatives contracts involves each Fund entering into contractual commitments to purchase or sell a commodity, currency or spot volatility product underlying such Fund’s benchmark at a specified date and price, should it hold such derivative contract into the deliverable period. Should a Fund enter into a contractual commitment to sell a physical commodity, currency or spot volatility product, it would be required to make delivery of that commodity, currency or spot volatility product at the contract price and then repurchase the contract at prevailing market prices or settle in cash. Since the repurchase price to which the value of a commodity, currency or spot volatility product can rise is unlimited, entering into commitments to sell commodities, currencies or spot volatility products would expose a Fund to theoretically unlimited risk.

For more information, see “Item 3. Quantitative and Qualitative Disclosures About Market Risk” in this Quarterly Report on Form

10-Q.

Credit Risk

When a Fund enters into swap agreements, futures contracts or forward contracts, the Fund is exposed to credit risk that the counterparty to the contract will not meet its obligations.

The counterparty for futures contracts traded on United States and most foreign futures exchanges as well as certain swaps is the clearing house associated with the particular exchange. In general, clearing houses are backed by their corporate members who may be required to share in the financial burden resulting from the nonperformance by one of their members and, as such, should significantly reduce this credit risk. In cases where the clearing house is not backed by the clearing members (i.e., some foreign exchanges, which may become applicable in the future), it may be backed by a consortium of banks or other financial institutions.

Certain swap and forward agreements are contracted for directly with counterparties. There can be no assurance that any counterparty, clearing member or clearing house will meet its obligations to a Fund.

156

Swap agreements do not generally involve the delivery of underlying assets either at the outset of a transaction or upon settlement. Accordingly, if the counterparty to an uncleared swap agreement defaults, the Fund’s risk of loss typically consists of the net amount of payments that the Fund is contractually entitled to receive, if any. Swap counterparty risk is generally limited to the amount of any unrealized gains, although in the event of a counterparty bankruptcy, there could be delays and costs associated with the recovery of collateral posted in segregated tri-party accounts at the Fund’s custodian bank.

Forward agreements do not involve the delivery of assets at the onset of a transaction, but may be settled physically in the underlying asset if such contracts are held to expiration, particularly in the case of currency forwards. Thus, prior to settlement, if the counterparty to a forward contract defaults, a Fund’s risk of loss will generally consist of the net amount of payments that the Fund is contractually entitled to receive, if any. However, if physically settled forwards are held until expiration (presently, there is no plan to do this), at the time of settlement, a Fund may be at risk for the full notional value of the forward contracts depending on the type of settlement procedures used.

The Sponsor attempts to minimize certain of these market and credit risks by normally:

• executing and clearing trades with creditworthy counterparties, as determined by the Sponsor;

• limiting the outstanding amounts due from counterparties to the Funds;

• not posting margin directly with a counterparty;

• requiring that the counterparty posts collateral in amounts approximately equal to that owed to the Funds, as marked to market daily, subject to certain minimum thresholds; and

• ensuring that deliverable contracts are not held to such a date when delivery of the underlying asset could be called for.

Off-Balance Sheet Arrangements and Contractual Obligations

As of August 2, 2018, the Funds have not used, nor do they expect to use in the future, special purpose entities to facilitate off-balance sheet financing arrangements and have no loan guarantee arrangements or off-balance sheet arrangements of any kind other than agreements entered into in the normal course of business, which may include indemnification provisions related to certain risks service providers undertake in performing services which are in the best interests of the Funds. While each Fund’s exposure under such indemnification provisions cannot be estimated, these general business indemnifications are not expected to have a material impact on a Fund’s financial position.

Management fee payments made to the Sponsor are calculated as a fixed percentage of each Fund’s NAV. As such, the Sponsor cannot anticipate the payment amounts that will be required under these arrangements for future periods as NAVs are not known until a future date. The agreement with the Sponsor may be terminated by either party upon 30 days written notice to the other party.

Critical Accounting Policies

The Trust’s and the Funds’ critical accounting policies are as follows:

Preparation of the financial statements and related disclosures in compliance with accounting principles generally accepted in the United States of America requires the application of appropriate accounting rules and guidance, as well as the use of estimates. The Trust’s and the Funds’ application of these policies involves judgments and actual results may differ from the estimates used.

Each Fund has significant exposure to Financial Instruments. The Funds hold a significant portion of their assets in swaps, futures, forward contracts or foreign currency forward contracts, all of which are recorded on a trade date basis and at fair value in the financial statements, with changes in fair value reported in the Statements of Operations.

157

The use of fair value to measure Financial Instruments, with related unrealized gains or losses recognized in earnings in each period, is fundamental to the Trust’s and the Funds’ financial statements. The fair value of a Financial Instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price).

For financial reporting purposes, the Funds value investments based upon the closing price in their primary markets. Accordingly, the investment valuations in these financial statements may differ from those used in the calculation of certain Funds’ final creation/redemption NAV for the three and six months ended June 30, 2018.

Short-term investments are valued at amortized cost which approximates fair value for daily NAV purposes. For financial reporting purposes, short-term investments are valued at their market price using information provided by a third-party pricing service or market quotations.

Derivatives (e.g., futures contracts, swap agreements, forward agreements and foreign currency forward contracts) are generally valued using independent sources and/or agreements with counterparties or other procedures as determined by the Sponsor. Futures contracts, except for those entered into by the Gold, Silver, Australian Dollar and Short Euro Funds, are generally valued at the last settled price on the applicable exchange on which that future trades. Futures contracts entered into by the Gold, Silver, Australian Dollar and Short Euro Funds are valued at the last sales price prior to the time at which the NAV per Share of a Fund is determined. For financial reporting purposes, all futures contracts are valued at last settled price. If there was no sale on that day, and for non-exchange-traded derivatives, the Sponsor may in its sole discretion choose to determine a fair value price as the basis for determining the market value of such position for such day. Such fair value prices would be generally determined based on available inputs about the current value of the underlying financial instrument or commodity and would be based on principles that the Sponsor deems fair and equitable so long as such principles are consistent with normal industry standards. When market closing prices are not available, the Sponsor may fair value an asset of a Fund pursuant to the policies the Sponsor has adopted, which are consistent with normal industry standards.

Fair value pricing may require subjective determinations about the value of an investment. While each Leveraged and VIX Fund’s policy is intended to result in a calculation of the Leveraged or the VIX Fund’s NAV that fairly reflects investment values as of the time of pricing, the Leveraged and the VIX Funds cannot ensure that fair values determined by the Sponsor or persons acting at their direction would accurately reflect the price that the Leveraged or the VIX Fund could obtain for an investment if it were to dispose of that investment as of the time of pricing (for instance, in a forced or distressed sale).

The prices used by the Leveraged or the VIX Fund may differ from the value that would be realized if the investments were sold and the differences could be material to the financial statements.

The Funds disclose the fair value of their investments in a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value.

Discounts on short-term securities purchased are amortized and reflected as Interest Income in the Statements of Operations.

Realized gains (losses) and changes in unrealized gain (loss) on open positions are determined on a specific identification basis and recognized in the Statements of Operations in the period in which the contract is closed or the changes occur, respectively.

Each Fund pays its respective brokerage commissions, including applicable exchange fees, NFA fees, give-up fees, pit brokerage fees and other transaction related fees and expenses charged in connection with trading activities for each Fund’s investment in U.S. Commodity Futures Trading Commission regulated investments. Brokerage commissions on futures contracts are recognized on a half-turn basis. The Sponsor is currently paying brokerage commissions on VIX futures contracts for the Matching VIX Funds that exceed variable create/redeem fees collected by more than 0.02% of the Matching VIX Fund’s average net assets annually.

Results of Operations for the Three Months Ended June 30, 2018 Compared to the Three Months Ended June 30, 2017

ProShares Short Euro

Fund Performance

The following table provides summary performance information for the Fund for the three months ended June 30, 2018 and 2017:

	Three Months Ended June 30, 2018			Three Months Ended June 30, 2017
NAV beginning of period	$	7,850,562		$	15,578,470

Percentage change in NAV		6.0	%		(33.0	)%
Shares outstanding beginning of period		200,000			350,000
Shares outstanding end of period		200,000			250,000
Percentage change in shares outstanding		0.0	%		(28.6	)%
Shares created		—			—
Shares redeemed		—			100,000
Per share NAV beginning of period	$	39.25		$	44.51
Per share NAV end of period	$	41.60		$	41.74
Percentage change in per share NAV		6.0	%		(6.2	)%
Percentage change in benchmark		(5.1	)%		7.1	%
Benchmark annualized volatility		7.4	%		7.4	%

During the three months ended June 30, 2018, the increase in the Fund’s NAV resulted from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to the inverse (-1x) of the daily performance of the spot price of the euro versus the U.S. dollar. There was no net change in the Fund’s outstanding Shares from March 31, 2018 to June 30, 2018. By comparison, during the three months ended June 30, 2017, the decrease in the Fund’s NAV resulted primarily from a decrease from 350,000 outstanding Shares at March 31, 2017 to 250,000 outstanding Shares at June 30, 2017. The decrease in the Fund’s NAV also resulted in part from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to the inverse (-1x) of the daily performance of the spot price of the euro versus the U.S. dollar.

For the three months ended June 30, 2018 and 2017 the Fund’s daily performance had a statistical correlation over 0.99 of the inverse of the daily performance of its benchmark. The Fund’s per Share NAV increase of 6.0% for the three months ended June 30, 2018, as compared to the Fund’s per Share NAV decrease of 6.2% for the three months ended June 30, 2017, was primarily due to an appreciation in the value of the assets of the Fund during the three months ended June 30, 2018.

During the three months ended June 30, 2018, the Fund’s per Share NAV reached its high for the period on June 27, 2018 at $42.00 per Share and reached its low for the period on April 16, 2018 at $39.02 per Share. By comparison, during the three months ended June 30, 2017, the Fund’s per Share NAV reached its high for the period on April 10, 2017 at $44.89 per Share and reached its low for the period on June 29, 2017 at $41.66 per Share.

The benchmark’s decline of 5.1% for the three months ended June 30, 2018, as compared to the benchmark’s rise of 7.1% for the three months ended June 30, 2017, can be attributed to a decline in the value of the euro versus the U.S. dollar during the period ended June 30, 2018.

Net Income/Loss

The following table provides summary income information for the Fund for the three months ended June 30, 2018 and 2017:

	Three Months Ended June 30, 2018		Three Months Ended June 30, 2017
Net investment income (loss)	$	7,908	$	(11,755	)

Change in net unrealized appreciation/depreciation		17,048		(66,049	)
Net income (loss)	$	468,767	$	(895,844	)

The Fund’s net income increased for the three months ended June 30, 2018, as compared to the three months ended June 30, 2017, primarily due to a decrease in the value of the euro versus the U.S. dollar during the three months ended June 30, 2018.

Percentage change in benchmark		(23.1	)%		(18.7	)%
Benchmark annualized volatility		59.9	%		56.3	%

During the three months ended June 30, 2018, the decrease in the Fund’s NAV resulted from a decrease from 59,800,000 outstanding Shares at March 31, 2018 to 41,350,000 outstanding Shares at June 30, 2018. The decrease in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to one-half the inverse (-0.5x) of the daily performance of the S&P 500 VIX Short-Term Futures Index. By comparison, during the three months ended June 30, 2017, the increase in the Fund’s NAV resulted primarily from an increase from 6,900,000 outstanding Shares at March 31, 2017 to 9,900,000 outstanding Shares at June 30, 2017. The increase in the Fund’s NAV also resulted in part from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to the inverse (-1x) of the daily performance of the S&P 500 VIX Short-Term Futures Index.

For the three months ended June 30, 2018, the Fund’s daily performance had a statistical correlation over 0.99 to 0.5x of the inverse of the daily performance of its benchmark. For the three months ended June 30, 2017, the Fund’s daily performance had a statistical correlation over ..99 to the inverse of the daily performance of its benchmark. The Fund’s per Share NAV increase of 10.2% for the three months ended June 30, 2018, as compared to the Fund’s per Share NAV increase of 13.6% for the three months ended June 30, 2017, was primarily due to a lesser appreciation in the value of the assets of the Fund during the three months ended June 30, 2018.

160

During the three months ended June 30, 2018, the Fund’s per Share NAV reached its high for the period on June 18, 2018 at $13.99 per Share and reached its low for the period on April 2, 2018 at $11.20 per Share. By comparison, during the three months ended June 30, 2017, the Fund’s per Share NAV reached its high for the period on June 26, 2017 at $84.17 per Share and reached its low for the period on April 13, 2017 at $60.18 per Share.

The benchmark’s decline of 23.1% for the three months ended June 30, 2018, as compared to the benchmark’s decline of 18.7% for the three months ended June 30, 2017, can be attributed to a greater decline of the prices of the near-term futures contracts on the VIX futures curve during the three months ended June 30, 2018.

Net Income/Loss

The following table provides summary income information for the Fund for the three months ended June 30, 2018 and 2017:

	Three Months Ended June 30, 2018			Three Months Ended June 30, 2017
Net investment income (loss)	$	(645,154	)	$	(1,366,200	)

Net income (loss)	$	69,583,789		$	156,943,095

The Fund’s net income decreased for the three months ended June 30, 2018, as compared to the three months ended June 30, 2017, primarily due to a greater decline in the prices of the near-term futures contracts on the VIX futures curve during the three months ended June 30, 2018.

During the three months ended June 30, 2018, the increase in the Fund’s NAV resulted from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to two times (2x) the daily performance of the Bloomberg WTI Crude Oil Subindex^SM. The increase in the Fund’s NAV was offset by a decrease from 14,961,317 outstanding Shares at March 31, 2018 to 13,261,317 outstanding Shares at June 30, 2018. By comparison, during the three months ended June 30, 2017, the increase in the Fund’s NAV resulted from an increase from 46,611,317 outstanding Shares at March 31, 2017 to 64,761,317 outstanding Shares at June 30, 2017. The increase in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to two times (2x) the daily performance of the Bloomberg WTI Crude Oil Subindex^SM.

For the three months ended June 30, 2018 and 2017, the Fund’s daily performance had a statistical correlation over 0.99 to 2x of the daily performance of its benchmark.

During the three months ended June 30, 2018, the decrease in the Fund’s NAV resulted from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to two times (2x) the daily performance of the spot price of the Japanese yen versus the U.S. dollar. There was no net change in the Fund’s outstanding Shares from March 31, 2018 to June 30, 2018.

During the three months ended June 30, 2018, the decrease in the Fund’s NAV resulted from a decrease from 9,250,000 outstanding Shares at March 31, 2018 to 7,800,000 outstanding Shares at June 30, 2018. The decrease in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to two times the inverse (-2x) of the daily performance of the spot price of the euro versus the U.S. dollar. By comparison, during the three months ended June 30, 2017, the decrease in the Fund’s NAV resulted primarily from a decrease from 11,250,000 outstanding Shares at March 31, 2017 to 10,250,000 outstanding Shares at June 30, 2017. The decrease in the Fund’s NAV also resulted in part from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to two times the inverse (-2x) of the daily performance of the spot price of the euro versus the U.S. dollar.

For the three months ended June 30, 2018 and 2017, the Fund’s daily performance had a statistical correlation over 0.99 to 2x of the inverse of the daily performance of its benchmark.

During the three months ended June 30, 2018, the Fund’s per Share NAV reached its high for the period on May 29, 2018 at $23.27 per Share and reached its low for the period on April 16, 2018 at $20.13 per Share.

The benchmark’s decline of 5.1% for the three months ended June 30, 2018, as compared to the benchmark’s rise of 7.1% for the three months ended June 30, 2017, can be attributed to a decline in the value of the euro versus the U.S. dollar during the three months ended June 30, 2018.

During the six months ended June 30, 2018, the increase in the Fund’s NAV resulted from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to the inverse (-1x) of the daily performance of the spot price of the euro versus the U.S. dollar. There was no net change in the Fund’s outstanding Shares from December 31, 2017 to June 30, 2018. By comparison, during the six months ended June 30, 2017, the decrease in the Fund’s NAV resulted primarily from a decrease from 350,000 outstanding Shares at December 31, 2016 to 250,000 outstanding Shares at June 30, 2017. The decrease in the Fund’s NAV also resulted in part from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to the inverse (-1x) of the daily performance of the spot price of the euro versus the U.S. dollar.

For the six months ended June 30, 2018 and 2017, the Fund’s daily performance had a statistical correlation over 0.99 of the inverse of the daily performance of its benchmark. The Fund’s per Share NAV increase of 4.1% for the six months ended June 30, 2018, as compared to the Fund’s per Share NAV decrease of 7.4% for the six months ended June 30, 2017, was primarily due to an appreciation in the value of the assets held by the Fund during the six months ended June 30, 2018.

During the six months ended June 30, 2018, the Fund’s per Share NAV reached its high for the period on June 27, 2018 at $42.00 per Share and reached its low for the period on February 1, 2018 at $38.43 per Share. By comparison, during the six months ended June 30, 2017, the Fund’s per Share NAV reached its high for the period on January 3, 2017 at $45.65 per Share and reached its low for the period on June 29, 2017 at $41.66 per Share.

The benchmark’s decline of 2.7% for the six months ended June 30, 2018, as compared to the benchmark’s rise of 8.5% for the six months ended June 30, 2017, can be attributed to a decrease in the value of the euro versus the U.S. dollar during the period ended June 30, 2018.

During the six months ended June 30, 2018, the decrease in the Fund’s NAV resulted from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to the inverse (-1x) of the daily performance of the S&P 500 VIX Short-Term Futures Index prior to the close of business on February 27, 2018, and one-half the inverse (-0.5x) of the daily performance of the S&P 500 VIX Short-Term Futures Index, effective as of the close of business, February 27, 2018, through the end of the reporting period. The decrease in the Fund’s NAV was offset by an increase from 6,050,000 outstanding Shares at December 31, 2017 to 41,350,000 outstanding Shares at June 30, 2018. By comparison, during the six months ended June 30, 2017, the increase in the Fund’s NAV resulted primarily from an increase from 5,000,000 outstanding Shares at December 31, 2016 to 9,900,000 outstanding Shares at June 30, 2017. The increase in the Fund’s NAV also resulted in part from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to the inverse (-1x) of the daily performance of the S&P 500 VIX Short-Term Futures Index.

For the six months ended June 30, 2018 and 2017, the Fund’s daily performance had a statistical correlation over 0.99 of the inverse of the daily performance of its benchmark prior to the close of business on February 27, 2018, and to one-half the inverse of the daily performance of its benchmark as of the close of business, February 27, 2018, through the end of the reporting period. The Fund’s per Share NAV decrease of 90.0% for the six months ended June 30, 2018, as compared to the Fund’s per Share NAV increase of 75.6% for the six months ended June 30, 2017, was primarily due to a rise in prices of the first and second month VIX futures during the six months ended June 30, 2018.

During the six months ended June 30, 2018, the Fund’s per Share NAV reached its high for the period on January 11, 2018 at $138.18 per Share and reached its low for the period on February 5, 2018 at $3.96 per Share.

The benchmark’s rise of 31.6% for the six months ended June 30, 2018, as compared to the benchmark’s decline of 49.4% for the six months ended June 30, 2017, can be attributed to an increase of the prices of the near-term futures contracts on the VIX futures curve during the six months ended June 30, 2018.

By comparison, during the six months ended June 30, 2017, the decrease in the Fund’s NAV resulted from a decrease from 2,800,000 outstanding Shares at December 31, 2016 to 2,350,000 outstanding Shares at June 30, 2017.

Benchmark annualized volatility		8.4	%		7.6	%

During the six months ended June 30, 2018, the decrease in the Fund’s NAV resulted from a decrease from 300,000 outstanding Shares at December 31, 2017 to 150,000 outstanding Shares at June 30, 2018. The decrease in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to two times the inverse (-2x) of the daily performance of the spot price of the Australian dollar versus the U.S. dollar. By comparison, during the six months ended June 30, 2017, the decrease in the Fund’s NAV resulted primarily from a decrease from 300,000 outstanding Shares at December 31, 2016 to 250,000 outstanding Shares at June 30, 2017. The decrease in the Fund’s NAV also resulted in part from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to two times the inverse (-2x) of the daily performance of the spot price of the Australian dollar versus the U.S. dollar.

For the six months ended June 30, 2018 and 2017, the Fund’s daily performance had a statistical correlation over 0.99 to 2x of the inverse of the daily performance of its benchmark.

During the six months ended June 30, 2018, the Fund’s per Share NAV reached its high for the period on June 27, 2018 at $51.44 per Share and reached its low for the period on January 26, 2018 at $42.30 per Share.

During the six months ended June 30, 2018, the decrease in the Fund’s NAV resulted primarily from a decrease from 1,749,290 outstanding Shares at December 31, 2017 to 1,149,290 outstanding Shares at June 30, 2018. The decrease in the Fund’s NAV also resulted in part from the cumulative effect of the Fund seeking daily investment results, before fees and expenses, that correspond to two times the inverse (-2x) of the daily performance of the spot price of the Japanese yen versus the U.S. dollar. By comparison, during the six months ended June 30, 2017, the decrease in the Fund’s NAV resulted primarily from a decrease from 3,449,290 outstanding Shares at December 31, 2016 to 2,299,290 outstanding Shares at June 30, 2017.

The Fund’s per Share NAV decrease of 1.9% for the six months ended June 30, 2018, as compared to the Fund’s per Share NAV decrease of 7.7% for the six months ended June 30, 2017, was primarily due to a lesser depreciation in the value of the assets held by the Fund during the six months ended June 30, 2018.

During the six months ended June 30, 2018, the Fund’s per Share NAV reached its high for the period on January 5, 2018 at $75.55 per Share and reached its low for the period on March 23, 2018 at $65.08 per Share.

Quantitative Disclosure

Exchange Rate Sensitivity, Equity Market Volatility Sensitivity, and Commodity Price Sensitivity

Each of the Funds is exposed to certain risks pertaining to the use of Financial Instruments. Each of the Currency Funds is exposed to exchange rate risk through its holdings of Financial Instruments. Each of the VIX Funds is exposed to equity market volatility risk through its holdings of Financial Instruments. Each of the Commodity Funds and Commodity Index Funds is exposed to commodity price risk through its holdings of Financial Instruments.

The tables below provide information about each of the Currency Funds’ Financial Instruments, VIX Funds’ Financial Instruments, and Commodity Funds’ and the Commodity Index Funds’ Financial Instruments. As of June 30, 2018 and 2017, each of the Funds’ positions were as follows:

ProShares Short Euro:

As of June 30, 2018 and 2017, the ProShares Short Euro Fund was exposed to inverse exchange rate price risk through its holdings of Euro/USD foreign currency futures contracts. The following table provides information about the Fund’s positions in these Financial Instruments as of June 30, 2018 and 2017, which were sensitive to exchange rate price risk.

	Futures Positions as of June 30, 2018
Contract	Long or Short	Expiration	Contracts		Valuation Price		Contract Multiplier		Notional Amount at Value
Euro Fx Currency Futures (CME)	Short	September 2018		57	$	1.1737		125,000	$	(8,362,256	)

		Futures Positions as of June 30, 2017
Contract	Long or Short	Expiration	Contracts		Valuation Price		Contract Multiplier		Notional Amount at Value
Euro Fx Currency Futures (CME)	Short	September 2017		73	$	1.1467		125,000	$	(10,463,638	)

The June 30, 2018 and 2017 short futures notional values are calculated by multiplying the number of contracts held times the valuation price times the contract multiplier. The short notional values will increase (decrease) proportionally with decreases (increases) in the price of the futures contract. Additional gains (losses) associated with these contracts will be equal to any such subsequent decreases (increases) in short notional values, before accounting for spreads or transaction or financing costs. The Fund will generally attempt to adjust its positions in Financial Instruments each day to have $1.00 of short exposure to the euro for every $1.00 of net assets. Future period returns, before fees and expenses, cannot be estimated simply by estimating the appreciation or depreciation of the euro and multiplying by negative one. See “Item 1A. Risk Factors” in the Form 10-K/A for additional information regarding performance for periods longer than a single day.

ProShares Short VIX Short-Term Futures ETF:

As of June 30, 2018 and 2017, the ProShares Short VIX Short-Term Futures ETF Fund was exposed to inverse equity market volatility risk through its holding of VIX futures contracts.

The June 30, 2018 and 2017 short futures notional values are calculated by multiplying the number of contracts held times the valuation price times the contract multiplier. The short notional values will increase (decrease) proportionally with decreases (increases) in the price of the futures contract. Additional gains (losses) associated with these contracts will be equal to any such subsequent decreases (increases) in short notional values, before accounting for spreads or transaction or financing costs. Prior to the close of business on February 27, 2018, the Fund generally attempted to adjust its positions in Financial Instruments each day to have $1.00 of short exposure to the Index for every $1.00 of net assets.

The June 30, 2018 and 2017 futures notional values are calculated by multiplying the number of contracts held times the valuation price times the contract multiplier. The June 30, 2018 and 2017 swap notional values are calculated by multiplying the number of units times the closing level of the Index. These notional values will increase (decrease) proportionally with increases (decreases) in the price of the futures contract or the level of the Index, as applicable. Additional gains (losses) associated with these contracts will be equal to any such subsequent increases (decreases) in notional values, before accounting for spreads or transaction or financing costs. The Fund will generally attempt to adjust its positions in Financial Instruments each day to have $2.00 of exposure to the Index for every $1.00 of net assets. Future period returns, before fees and expenses, cannot be estimated simply by estimating the return of the Index and multiplying by two. See “Item 1A. Risk Factors” in the Form 10-K/A for additional information regarding performance for periods longer than a single day. Swap counterparty risk is generally limited to the amount of any unrealized gains, although in the event of a counterparty bankruptcy, there could be delays and costs associated with recovering collateral posted in segregated tri-party accounts at the Fund’s custodian bank.

The June 30, 2018 and 2017 USD market value equals the number of euros multiplied by the forward rate.

These notional values will increase (decrease) proportionally with increases (decreases) in the forward price. Additional gains (losses) associated with these contracts will be equal to any such subsequent increases (decreases) in notional values, before accounting for spreads or transaction or financing costs. The Fund will generally attempt to adjust its positions in Financial Instruments each day to have $2.00 of exposure to the euro for every $1.00 of net assets. Future period returns, before fees and expenses, cannot be estimated simply by estimating the appreciation or depreciation of the euro and multiplying by two. See “Item 1A. Risk Factors” in the Form 10-K/A for additional information regarding performance for periods longer than a single day. Counterparty risk related to foreign currency forward contracts is generally limited to the amount of any unrealized gains, although in the event of a counterparty bankruptcy, there could be delays and costs associated with recovering collateral posted in segregated tri-party accounts at the Fund’s custodian bank.

The June 30, 2018 and 2017 USD market values equal the number of euros multiplied by the forward rate. These short notional values will increase (decrease) proportionally with decreases (increases) in the forward price. Additional gains (losses) associated with these contracts will be equal to any such subsequent decreases (increases) in short notional values, before accounting for spreads or transaction or financing costs. The Fund will generally attempt to adjust its positions in Financial Instruments each day to have $2.00 of short exposure to the euro for every $1.00 of net assets. Future period returns, before fees and expenses, cannot be estimated simply by estimating the appreciation or depreciation of the euro and multiplying by negative two. See “Item 1A. Risk Factors” in the Form 10-K/A for additional information regarding performance for periods longer than a single day. Counterparty risk related to foreign currency forward contracts is generally limited to the amount of any unrealized gains, although in the event of a counterparty bankruptcy, there could be delays and costs associated with recovering collateral posted in segregated tri-party accounts at the Fund’s custodian bank.

Qualitative Disclosure

As described above in Item 2 in this Quarterly Report on Form 10-Q, it is the investment objective of each Geared Fund to seek daily investment results, before fees and expenses, which correspond to a multiple, the inverse or an inverse multiple of the daily performance, of its corresponding benchmark. Each Short Fund seeks daily investment results, before fees and expenses, that correspond to one-half the inverse (-0.5x) or the inverse (-1x) of the daily performance of its corresponding benchmark. Each UltraShort Fund seeks daily investment results, before fees and expenses, that correspond to two times the inverse (-2x) of the daily performance of its corresponding benchmark. Each Ultra Fund seeks daily investment results, before fees and expenses, that correspond to one and one-half times (1.5x) or two times (2x) the daily performance of its corresponding benchmark. Each UltraPro Short Fund seeks daily investment results, before fees and expenses, that correspond to three times the inverse (-3x) of daily performance of its corresponding benchmark. Each UltraPro Fund seeks daily investment results, before fees and expenses, that correspond to three times (3x) daily performance of its corresponding benchmark. Each Matching VIX Fund seeks investment results before fees and expenses, that match the performance of a benchmark. The Geared Funds do not seek to achieve these stated investment objectives over a period of time greater than a single day because mathematical compounding prevents the Geared Funds from achieving such results. Performance over longer periods of time will be influenced not only by the cumulative period performance of the corresponding benchmark but equally by the intervening volatility of the benchmark as well as fees and expenses, including costs associated with the use of Financial Instruments such as financing costs and trading spreads. Future period returns, before fees and expenses, cannot be estimated simply by estimating the percent change in the corresponding benchmark and multiplying by negative three, negative two, negative one, negative one-half, one, one and one-half, two or three. Shareholders who invest in the Funds should actively manage and monitor their investments, as frequently as daily. See “Item 1A. Risk Factors” in the Form 10-K/A for additional information regarding performance for periods longer than a single day.

228

Primary Market Risk Exposure

The primary market risks that the Funds are exposed to depend on each Fund’s investment objective and corresponding benchmark. For example, the primary market risk that the ProShares UltraShort Bloomberg Crude Oil and the ProShares Ultra Bloomberg Crude Oil Funds are exposed to are inverse and long exposure, respectively, to the price of crude oil as measured by the return of holding and periodically rolling crude oil futures contracts (the Bloomberg Commodity Index and its sub-indexes are based on the price of rolling futures positions, rather than on the cash price for immediate delivery of the corresponding commodity).

Each Fund’s exposure to market risk is further influenced by a number of factors, including the liquidity of the markets in which the contracts are traded and the relationships among the contracts held. The inherent uncertainty of each Fund’s trading strategies and other factors, could ultimately lead to a loss of all or substantially all of investors’ capital.

As described above in Item 2 in this Quarterly Report on Form 10-Q, trading in certain futures contracts or forward agreements involves each Fund entering into contractual commitments to purchase or sell a commodity underlying a Fund’s benchmark at a specified date and price, should it hold such futures contracts or forward agreements into the deliverable period. Should a Fund enter into a contractual commitment to sell a physical commodity, it is required to make delivery of that commodity at the contract price and then repurchase the contract at prevailing market prices or settle in cash. Since the repurchase price to which the value of a commodity can rise is unlimited, entering into commitments to sell commodities would expose a Fund to theoretically unlimited risk.

Commodity Price Sensitivity

As further described in “Item 1A. Risk Factors” in the Form 10-K/A, the value of the Shares of each Fund relates directly to the value of, and realized profit or loss from, the Financial Instruments and other assets held by the Fund and fluctuations in the price of these assets could materially adversely affect an investment in the Shares. With regard to the Commodity Index Funds or the Commodity Funds, several factors may affect the price of a commodity underlying a Commodity Index Fund or a Commodity Fund, and in turn, the Financial Instruments and other assets, if any, owned by such a Fund. The impact of changes in the price of a physical commodity or of a commodity index (comprised of commodity futures contracts) will affect investors differently depending upon the Fund in which investors invest. Daily increases in the price of an underlying commodity or commodity index will negatively impact the daily performance of Shares of an UltraShort Fund and daily decreases in the price of an underlying commodity or commodity index will negatively impact the daily performance of Shares of an Ultra Fund.

Additionally, performance over time is a cumulative effect of geometrically linking each day’s leveraged or inverse leveraged returns. For instance, if a corresponding benchmark was up 10% and then down 10%, which would result in a (1.1*0.9)-1 = -1% period benchmark return, the two-day period return for a theoretical two-times fund would be equal to a (1.2 *0.8)-1 = -4% period Fund return (rather than simply two times the period return of the benchmark).

Exchange Rate Sensitivity

As further described in “Item 1A. Risk Factors” in the Form 10-K/A, the value of the Shares of each Fund relates directly to the value of, and realized profit or loss from, the Financial Instruments and other assets held by the Fund and fluctuations in the price of these assets could materially adversely affect an investment in the Shares. With regard to the Currency Funds, several factors may affect the value of the foreign currencies or the U.S. dollar, and, in turn, the Financial Instruments and other assets, if any, owned by a Fund. The impact of changes in the price of a currency will affect investors differently depending upon the Fund in which investors invest. Daily increases in the price of a currency will negatively impact the daily performance of Shares of a Short Fund or an UltraShort Fund and daily decreases in the price of a currency will negatively impact the daily performance of Shares of an Ultra Fund.

Additionally, performance over time is a cumulative effect of geometrically linking each day’s leveraged or inverse leveraged returns. For instance, if a corresponding benchmark was up 10% and then down 10%, which would result in a (1.1*0.9)-1 = -1% period benchmark return, the two-day period return for a theoretical two-times fund would be equal to a (1.2 *0.8)-1 = -4% period Fund return (rather than simply two times the period return of the benchmark).

229

Equity Market Volatility Sensitivity

As further described in “Item 1A. Risk Factors” in the Form 10-K/A, the value of the Shares of each VIX Fund relates directly to the value of, and realized profit or loss from, the Financial Instruments and other assets held by the Fund and fluctuations in the price of these assets could materially adversely affect an investment in the Shares. Several factors may affect the price and/or liquidity of VIX futures contracts and other assets, if any, owned by a VIX Fund. The impact of changes in the price of these assets will affect investors differently depending upon the Fund in which investors invest.

Managing Market Risks

Each Fund seeks to remain fully exposed to the corresponding benchmark at the levels implied by the relevant investment objective (-0.5x, -1x, -2x, 1.5x, 2x, -3x, 3x), regardless of market direction or sentiment. At the close of the relevant markets each trading day (see NAV calculation times), each Fund will seek to position its portfolio so that its exposure to its benchmark is consistent with its investment objective. As described above in Item 2 of this Quarterly Report on Form 10-Q, these adjustments are done through the use of various Financial Instruments. No attempt is made to adjust market exposure in order to avoid changes to the benchmark that would cause the Funds to lose value. Factors common to all Funds that may require portfolio re-positioning are create/redeem activity and index rebalances.

For Geared Funds, the impact of the index’s movements each day also affects whether the Fund’s portfolio needs to be rebalanced. For example, if the index for an Ultra Fund or UltraPro Fund has risen on a given day, net assets of the Fund should rise. As a result, the Fund’s long exposure will need to be increased to the extent there are not offsetting factors such as redemption activity. Conversely, if the Index has fallen on a given day, net assets of an Ultra Fund or UltraPro Fund should fall. As a result, the Fund’s long exposure will generally need to be decreased. Net assets for Short Funds, UltraShort Funds or UltraPro Short Funds will generally decrease when the Index rises on a given day. As a result, the Fund’s short exposure may need to be decreased. Conversely, if the Index has fallen on a given day, a Short Fund’s, an UltraShort Fund’s, or UltraPro Short Fund’s assets should rise. As a result, the Fund’s short exposure may need to be increased.

The use of certain Financial Instruments introduces counterparty risk. A Fund will be subject to credit risk with respect to the amount it expects to receive from counterparties to Financial Instruments entered into by the Fund. A Fund may be negatively impacted if a counterparty fails to perform its obligations. Each Fund intends to enter into swap and forward agreements only with major global financial institutions that meet certain credit quality standards and monitoring policies. Each Fund may use various techniques to minimize credit risk including early termination or reset and payment, limiting the net amount due from any individual counterparty, and generally requiring that the counterparty post collateral with respect to amounts owed to the Funds, marked to market daily.

Most Financial Instruments held by the Funds are “unfunded” meaning that the Fund will obtain exposure to the corresponding benchmark while still being in possession of its original cash assets. The cash positions that result from use of such Financial Instruments are held in a manner to minimize both interest rate and credit risk. During the reporting period, cash positions were maintained in both non-interest bearing and interest bearing demand deposit accounts. The Funds may also invest a portion of this cash in cash equivalents (such as shares of money market funds, bank deposits, bank money market accounts, certain variable rate-demand notes and repurchase agreements collateralized by government securities).

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

a) None.

b) The Trust initially registered Shares on its Registration Statement on Form S-1 (File No. 333-146801), which was declared effective on November 21, 2008, and registered additional Shares on its Registration Statement on Form S-1 (File No. 333-156888), which was declared effective on February 13, 2009. The Trust terminated these two offerings before the sale of all registered Shares and reallocated the remaining amount of the registered Shares among the Funds listed on its Registration Statement on Form S-3 (File No. 333-163511), which became effective on December 4, 2009. It then registered additional Shares and/or added Funds pursuant to post-effective amendments to that Registration Statement on Form S-3, which became effective on May 28, 2010, November 5, 2010, December 23, 2010 and April 13, 2011, as well as on a Registration Statement on Form S-1 (File No. 333-178707), which became effective on June 25, 2012.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization

NOTE 1 – ORGANIZATION

ProShares Trust II (the “Trust”) is a Delaware statutory trust formed on October 9, 2007 and is currently organized into separate series (each, a “Fund” and collectively, the “Funds”). As of June 30, 2018, the following twenty series of the Trust have commenced investment operations: (i) ProShares VIX Short-Term Futures ETF and ProShares VIX Mid-Term Futures ETF (each, a “Matching VIX Fund” and collectively, the “Matching VIX Funds”); (ii) ProShares Short VIX Short-Term Futures ETF and ProShares Ultra VIX Short-Term Futures ETF (each, a “Geared VIX Fund” and collectively, the “Geared VIX Funds”); (iii) ProShares UltraShort Bloomberg Crude Oil, ProShares UltraPro 3x Short Crude Oil ETF, ProShares UltraShort Bloomberg Natural Gas, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Australian Dollar, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Crude Oil, ProShares UltraPro 3x Crude Oil ETF, ProShares Ultra Bloomberg Natural Gas, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen (each, a “Leveraged Fund” and collectively, the “Leveraged Funds”); and (iv) ProShares Short Euro (the “Short Euro Fund”). Each of the Funds listed above issues common units of beneficial interest (“Shares”), which represent units of fractional undivided beneficial interest in and ownership of only that Fund. The Shares of each Fund are listed on the New York Stock Exchange Archipelago (“NYSE Arca”). The Leveraged Funds, the Short Euro Fund and the Geared VIX Funds, are collectively referred to as the “Geared Funds” in these Notes to Financial Statements. The Geared VIX Funds and the Matching VIX Funds are collectively referred to as the “VIX Funds” in these Notes to Financial Statements.

The Trust had no operations prior to November 24, 2008, other than matters relating to its organization, the registration of each series under the Securities Act of 1933, as amended, and the sale and issuance to ProShare Capital Management LLC (the “Sponsor”) of fourteen Shares at an aggregate purchase price of $350 in each of the following Funds: ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Crude Oil, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen.

Groups of Funds are collectively referred to in several different ways. References to “Short Funds,” “UltraShort Funds,” “UltraPro Short Funds,” “Ultra Funds,” or “UltraPro Funds” refer to the different Funds based upon their investment objectives, but without distinguishing among the Funds’ benchmarks.

References to “Commodity Index Funds,” “Commodity Funds” and “Currency Funds” refer to the different Funds according to their general benchmark categories without distinguishing among the Funds’ investment objectives or Fund-specific benchmarks. References to “VIX Funds” refer to the different Funds based upon their investment objective and their general benchmark categories.

Effective as of close of business on February 27, 2018, the investment objective of ProShares Ultra VIX Short-Term Futures ETF and ProShares Short VIX Short-Term Futures ETF changed.

ProShares Ultra VIX Short-Term Futures ETF changed its investment objective to seek daily investment results, before fees and expenses, that correspond to one and one-half times (1.5x) of the performance of the S&P 500 VIX Short-Term Futures Index for a single day. Prior to the close of business on February 27, 2018, the Fund’s investment objective was to seek results, before fees and expenses, that correspond to two times (2x) the performance of the Index for a single day.

ProShares Short VIX Short-Term Futures ETF changed its investment objective to seek daily investment results, before fees and expenses, that correspond to one-half the inverse (-0.5x) of the performance of the S&P 500 VIX Short-Term Futures Index for a single day. Prior to the close of business on February 27, 2018, the Fund’s investment objective was to seek results, before fees and expenses, that correspond to the inverse (-1x) of the Index for a single day.

Each “Short” Fund seeks daily investment results, before fees and expenses, that correspond to either one-half inverse (-0.5x) or inverse (-1x) of the daily performance of its corresponding benchmark. Each “UltraShort” Fund seeks daily investment results, before fees and expenses, that correspond to two times the inverse (-2x) of the daily performance of its corresponding benchmark. Each “UltraPro Short” Fund seeks daily investment results, before fees and expenses, that correspond to three times the inverse (-3x) of the daily performance of its corresponding benchmark. Each “Ultra” Fund seeks daily investment results, before fees and expenses, that correspond to either one and one-half times (1.5x) or two times (2x) the daily performance of its corresponding benchmark. Each “UltraPro” Fund seeks daily investment results, before fees and expenses, that correspond to three times (3x) the daily performance of its corresponding benchmark. Each Matching VIX Fund seeks investment results, before fees and expenses, that match the performance of its corresponding benchmark. Daily performance is measured from the calculation of one NAV to the next.

The Geared Funds do not seek to achieve their stated investment objective over a period of time greater than a single day because mathematical compounding prevents the Geared Funds from achieving such results. Accordingly, results over periods of time greater than a single day should not be expected to be a simple multiple (e.g., -0.5x, -1x, -2x, 1.5x, 2x, -3x or 3x) of the period return of the corresponding benchmark and will likely differ significantly.

As described in the prospectus for each Fund, each of the Funds intends to invest in financial instruments “Financial Instruments” (Financial Instruments are instruments whose value is derived from the value of an underlying asset, rate or benchmark, including futures contracts, swap agreements, forward contracts and other instruments) as a substitute for investing directly in commodities, currencies, or spot volatility products in order to gain exposure to the VIX Index, natural gas, crude oil, precious metals, or currencies, as applicable. Financial Instruments also are used to produce economically “inverse,” “inverse leveraged” or “leveraged” investment results for the Geared Funds.

Share Splits and Reverse Share Splits

The table below includes Share splits and reverse Share splits for the Funds during the year ended December 31, 2017 and during

six months ended June 30, 2018. The ticker symbols for these Funds did not change, and each Fund continues to trade on the NYSE Arca.

Fund	Execution Date     (Prior to Opening     of Trading)	Type of Split	Date Trading Resumed at Post- Split Price
ProShares UltraShort Bloomberg Crude Oil	January 11, 2017	2-for-1 Share split	January 12, 2017
ProShares Ultra Bloomberg Crude Oil	January 11, 2017	1-for-2 reverse Share split	January 12, 2017
ProShares Ultra VIX Short-Term Futures ETF	January 11, 2017	1-for-5 reverse Share split	January 12, 2017
ProShares Short VIX Short-Term Futures ETF	July 12, 2017	2-for-1 Share split	July 17, 2017
ProShares VIX Short-Term Futures ETF	July 14, 2017	1-for-4 reverse Share split	July 17, 2017
ProShares Ultra VIX Short-Term Futures ETF	July 14, 2017	1-for-4 reverse Share split	July 17, 2017
ProShares Ultra Bloomberg Natural Gas	March 19, 2018	1-for-5 reverse Share split	March 20, 2018
ProShares UltraPro 3x Short Crude Oil ETF	March 19, 2018	1-for-4 reverse Share split	March 20, 2018

The reverse splits were applied retroactively for all periods presented, reducing the number of Shares outstanding for each of the Funds, and resulted in a proportionate increase in the price per Share and per Share information of each such Fund. Therefore, the reverse splits did not change the aggregate net asset value of a shareholder’s investment at the time of the reverse split.

Accounting Policies [Abstract]

Significant Accounting Policies

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

Each Fund is an investment company, as defined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946 “Financial Services — Investment Companies.” As such, the Funds follow the investment company accounting and reporting guidance. The following is a summary of significant accounting policies followed by each Fund, as applicable, in preparation of its financial statements. These policies are in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Certain prior year amounts have been reclassified to conform to the current year presentation.

The accompanying unaudited financial statements were prepared in accordance with GAAP for interim financial information and with the instructions for Form 10-Q and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). In the opinion of management, all material adjustments, consisting only of normal recurring adjustments, considered necessary for a fair statement of the interim period financial statements have been made. Interim period results are not necessarily indicative of results for a full-year period. These financial statements and the notes thereto should be read in conjunction with the Trust’s and the Funds’ financial statements included in the Trust’s Annual Report on Form 10-K/A for the year ended December 31, 2017, as filed with the SEC on March 26, 2018.

Use of Estimates & Indemnifications

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

In the normal course of business, the Trust enters into contracts that contain a variety of representations which provide general indemnifications. The Trust’s maximum exposure under these arrangements cannot be known; however, the Trust expects any risk of loss to be remote.

Basis of Presentation

Pursuant to rules and regulations of the SEC, audited financial statements are presented for the Trust as a whole, as the SEC registrant, and for each Fund individually. The debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to a particular Fund shall be enforceable only against the assets of such Fund and not against the assets of the Trust generally or any other Fund. Accordingly, the assets of one Fund of the Trust include only those funds and other assets that are paid to, held by or distributed to the Trust for the purchase of Shares in that Fund.

Statement of Cash Flows

The cash amount shown in the Statements of Cash Flows is the amount reported as cash in the Statement of Financial Condition dated June 30, 2018, and represents cash, segregated cash balances with brokers for futures contracts, segregated cash with brokers for swap agreements, segregated cash with brokers for forward agreements, and segregated cash with brokers for foreign currency forward agreements but does not include short-term investments.

Final Net Asset Value for Fiscal Period

The cut-off times and the times of the calculation of the Funds’ final net asset value for creation and redemption of fund Shares for the six months ended June 30, 2018 were as follows. All times are Eastern Standard Time:

VIX Mid-Term Futures ETF	2:00 p.m.	4:15 p.m.	June 29, 2018

* Although the Funds’ shares may continue to trade on secondary markets subsequent to the calculation of the final NAV, these times represent the final opportunity to transact in creation or redemption units for the six months ended June 30, 2018.

Market value per Share is determined at the close of the NYSE Arca and may be later than when the Funds’ NAV per Share is calculated.

For financial reporting purposes, the Funds value transactions based upon the final closing price in their primary markets. Accordingly, the investment valuations in these financial statements may differ from those used in the calculation of certain of the Funds’ final creation/redemption NAV for the six months ended June 30, 2018.

Investment Valuation

Short-term investments are valued at amortized cost which approximates fair value for daily NAV purposes. For financial reporting purposes, short-term investments are valued at their market price using information provided by a third-party pricing service or market quotations. In each of these situations, valuations are typically categorized as Level I in the fair value hierarchy.

Derivatives (e.g., futures contracts, swap agreements, forward agreements and foreign currency forward contracts) are typically valued using independent sources and/or agreements with counterparties or other procedures as determined by the Sponsor. Futures contracts, except for those entered into by the Gold, Silver, Australian Dollar and Short Euro Funds, are typically valued at the last settled price on the applicable exchange on which that future trades. Futures contracts entered into by the Gold, Silver, Australian Dollar and Short Euro Funds are typically valued at the last sales price prior to the time at which the NAV per Share of a Fund is determined. For financial reporting purposes, all futures contracts are typically valued at the last settled price. Futures contracts valuations are typically categorized as Level I in the fair value hierarchy. Swap agreements, forward agreements and foreign currency forward contracts valuations are typically categorized as Level II in the fair value hierarchy. The Sponsor may in its sole discretion choose to determine a fair value price as the basis for determining the market value of such position. Such fair value prices would generally be determined based on available inputs about the current value of the underlying financial instrument or commodity and would be based on principles that the Sponsor deems fair and equitable so long as such principles are consistent with industry standards. The Sponsor may fair value an asset of a Fund pursuant to the policies the Sponsor has adopted, which are consistent with normal industry standards. Depending on the source and relevant significance of valuation inputs, these instruments may be classified as Level II or Level III in the fair value hierarchy.

Fair value pricing may require subjective determinations about the value of an investment. While the Funds’ policies are intended to result in a calculation of its respective Fund’s NAV that fairly reflects investment values as of the time of pricing, such Fund cannot ensure that fair values determined by the Sponsor or persons acting at their direction would accurately reflect the price that a Fund could obtain for an investment if it were to dispose of that investment as of the time of pricing (for instance, in a forced or distressed sale). The prices used by such Fund may differ from the value that would be realized if the investments were sold and the differences could be material to the financial statements.

Fair Value of Financial Instruments

The Funds disclose the fair value of their investments in a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The disclosure requirements establish a fair value hierarchy that distinguishes between: (1) market participant assumptions developed based on market data obtained from sources independent of the Funds (observable inputs); and (2) the Funds’ own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the disclosure requirements hierarchy are as follows:

Level I – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level II – Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level II assets include the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs).

Level III – Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available.

In some instances, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest input level that is significant to the fair value measurement in its entirety.

Fair value measurements also require additional disclosure when the volume and level of activity for the asset or liability have significantly decreased, as well as when circumstances indicate that a transaction is not orderly.

The following table summarizes the valuation of investments at June 30, 2018 using the fair value hierarchy:

* Includes cumulative appreciation/depreciation of futures contracts as reported in the Schedules of Investments. Only current day’s variation margin is reported within the Statements of Financial Condition in receivable/payable on open futures.

At June 30, 2018, there were no Level III portfolio investments for which significant unobservable inputs were used to determine fair value.

The Funds’ policy is to recognize transfers between valuation levels at the end of the reporting period.

At June 30, 2018, there were no significant transfers in or out of Level I and Level II fair value measurements.

The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those securities.

At December 31, 2017, there were no Level III portfolio investments for which significant unobservable inputs were used to determine fair value.

The Funds’ policy is to recognize transfers between valuation levels at the end of the reporting period.

At December 31, 2017, there were no significant transfers in or out of Level I and Level II fair value measurements.

The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those securities.

Investment Transactions and Related Income

Investment transactions are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized appreciation/depreciation on open contracts are reflected in the Statements of Financial Condition and changes in the unrealized appreciation/depreciation between periods are reflected in the Statements of Operations. Discounts on short-term securities purchased are amortized and reflected as Interest Income in the Statements of Operations.

Brokerage Commissions and Fees

Each Fund pays its respective brokerage commissions, including applicable exchange fees, National Futures Association (“NFA”) fees, give-up fees, pit brokerage fees and other transaction related fees and expenses charged in connection with trading activities for each Fund’s investment in U.S. Commodity Futures Trading Commission (“CFTC”) regulated investments. The effects of trading spreads, financing costs/fees associated with Financial Instruments, and costs relating to the purchase of U.S. Treasury securities or similar high credit quality short-term fixed-income would also be borne by the Funds. Brokerage commissions on futures contracts are recognized on a half-turn basis (e.g., the first half is recognized when the contract is purchased (opened) and the second half is recognized when the transaction is closed). The Sponsor is currently paying brokerage commissions on VIX futures contracts for the Matching VIX Funds that exceed variable create/redeem fees collected by more than 0.02% of the Matching VIX Fund’s average net assets annually.

Federal Income Tax

Each Fund is registered as a series of a Delaware statutory trust and is treated as a partnership for U.S. federal income tax purposes. Accordingly, no Fund expects to incur U.S. federal income tax liability; rather, each beneficial owner of a Fund’s Shares is required to take into account its allocable share of its Fund’s income, gain, loss, deductions and other items for its Fund’s taxable year ending with or within the beneficial owner’s taxable year.

Management of the Funds has reviewed all open tax years and major jurisdictions (i.e., the last four tax year ends and the interim tax period since then, as applicable) and concluded that there is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken in future tax returns. The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. On an ongoing basis, management will monitor its tax positions taken under the interpretation to determine if adjustments to conclusions are necessary based on factors including, but not limited to, on-going analysis of tax law, regulation, and interpretations thereof.

New Accounting Pronouncements

In November 2016, the FASB issued Accounting Standards Update No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash” (“ASU 2016-18”), which amends ASC 230 to provide guidance on the classification and presentation of changes in restricted cash and restricted cash equivalents on the statement of cash flows. The ASU has been adopted for the current reporting period under the retrospective transition method. The adoption had no significant impact to the Statement of Cash Flows.

Investments

NOTE 3 – INVESTMENTS

Short-Term Investments

The Funds may purchase U.S. Treasury Bills, agency securities, and other high-credit quality short-term fixed income or similar securities with original maturities of one year or less. A portion of these investments may be posted as collateral in connection with swap agreements, futures, and/or forward contracts.

Accounting for Derivative Instruments

In seeking to achieve each Fund’s investment objective, the Sponsor uses a mathematical approach to investing. Using this approach, the Sponsor determines the type, quantity and mix of investment positions, including derivative positions, which the Sponsor believes in combination, should produce returns consistent with a Fund’s objective.

All open derivative positions at period end are reflected on each respective Fund’s Schedule of Investments. Certain Funds utilized a varying level of derivative instruments in conjunction with investment securities in seeking to meet their investment objective during the period. While the volume of open positions may vary on a daily basis as each Fund transacts derivatives contracts in order to achieve the appropriate exposure to meet its investment objective, the volume of these open positions relative to the net assets of each respective Fund at the date of this report is generally representative of open positions throughout the reporting period.

As discussed in Note 1, the Short VIX Short-Term Futures ETF and the Ultra VIX Short-Term Futures ETF changed their investment objectives and target exposures as of the close of business on February 27, 2018. From this time through the effective end of the reporting period, the volume of the derivative exposure relative to the net assets was generally representative to their current investment objectives. From the beginning of the reporting period until the close of business on February 27, 2018, the volume of the derivative exposure relative to the net assets was generally representative to their previous investment objectives.

Following is a description of the derivative instruments used by the Funds during the reporting period, including the primary underlying risk exposures related to each instrument type.

Futures Contracts

The Funds may enter into futures contracts to gain exposure to changes in the value of, or as a substitute for investing directly in (or shorting), an underlying index, currency or commodity. A futures contract obligates the seller to deliver (and the purchaser to accept) the future delivery of a specified quantity and type of asset at a specified time and place. The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity, if applicable, or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery, or by cash settlement at expiration of contract.

Upon entering into a futures contract, each Fund is required to deposit and maintain as collateral at least such initial margin as required by the exchange on which the transaction is affected. The initial margin is segregated as cash and/or securities balances with brokers for futures contracts, as disclosed in the Statements of Financial Condition, and is restricted as to its use. The Funds that enter into futures contracts maintain collateral at the broker in the form of cash and/or securities. Pursuant to the futures contract, each Fund generally agrees to receive from or pay to the broker(s) an amount of cash equal to the daily fluctuation in value of the futures contract. Such receipts or payments are known as variation margin and are recorded by each Fund as unrealized gains or losses. Each Fund will realize a gain or loss upon closing of a futures transaction.

Futures contracts involve, to varying degrees, elements of market risk (specifically commodity price risk or equity market volatility risk) and exposure to loss in excess of the amount of variation margin. The face or contract amounts reflect the extent of the total exposure each Fund has in the particular classes of instruments. Additional risks associated with the use of futures contracts are imperfect correlation between movements in the price of the futures contracts and the market value of the underlying index or commodity and the possibility of an illiquid market for a futures contract. With futures contracts, there is minimal but some counterparty risk to the Funds since futures contracts are exchange-traded and the exchange’s clearinghouse, as counterparty to all exchange-traded futures contracts, guarantees the futures contracts against default. Many futures exchanges and boards of trade limit the amount of fluctuation permitted in futures contract prices during a single trading day. Once the daily limit has been reached in a particular contract, no trades may be made that day at a price beyond that limit or trading may be suspended for specified times during the trading day. Futures contracts prices could move to the limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and potentially subjecting a Fund to substantial losses. If trading is not possible, or if a Fund determines not to close a futures position in anticipation of adverse price movements, the Fund will be required to make daily cash payments of variation margin. The risk the Fund will be unable to close out a futures position will be minimized by entering into such transactions on a national exchange with an active and liquid secondary market.

Swap Agreements

Certain of the Funds enter into swap agreements for purposes of pursuing their investment objectives or as a substitute for investing directly in (or shorting) an underlying index, currency or commodity, or to create an economic hedge against a position. Swap agreements are two-party contracts that have traditionally been entered into primarily with institutional investors in over-the-counter (“OTC”) markets for a specified period, ranging from a day to more than one year. However, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) provides for significant reforms of the OTC derivative markets, including a requirement to execute certain swap transactions on a CFTC-regulated market and/or to clear such transactions through a CFTC-regulated central clearing organization. In a standard swap transaction, two parties agree to exchange the returns earned or realized on a particular predetermined investment, instrument or index in exchange for a fixed or floating rate of return in respect of a predetermined notional amount. Transaction or commission costs are reflected in the benchmark level at which the transaction is entered into. The gross returns to be exchanged are calculated with respect to a notional amount and the benchmark returns to which the swap is linked. Swap agreements do not involve the delivery of underlying instruments.

Generally, swap agreements entered into by the Funds calculate and settle the obligations of the parties to the agreement on a “net basis” with a single payment. Consequently, each Fund’s current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of such obligations (or rights) (the “net amount”). In a typical swap agreement entered into by a Matching VIX Fund, an Ultra Fund, or an UltraPro Fund, the Matching VIX Fund, Ultra Fund, or UltraPro Fund would be entitled to settlement payments in the event the level of the benchmark increases and would be required to make payments to the swap counterparties in the event the level of the benchmark decreases, adjusted for any transaction costs or trading spreads on the notional amount the Funds may pay. In a typical swap agreement entered into by a Short Fund, an UltraShort Fund, or an UltraPro Short Fund, the Short Fund, UlraShort Fund, or UltraPro Short Fund would be required to make payments to the swap counterparties in the event the level of the benchmark increases and would be entitled to settlement payments in the event the level of the benchmark decreases, adjusted for any transaction costs or trading spreads on the notional amount the Funds may pay.

The net amount of the excess, if any, of each Fund’s obligations over its entitlements with respect to each uncleared swap agreement is accrued on a daily basis and an amount of cash and/or securities having an aggregate value at least equal to such accrued excess is maintained for the benefit of the counterparty in a segregated account by the Funds’ Custodian. The net amount of the excess, if any, of each Fund’s entitlements over its obligations with respect to each uncleared swap agreement is accrued on a daily basis and an amount of cash and/or securities having an aggregate value at least equal to such accrued excess is maintained for the benefit of the Fund in a segregated account by the Fund’s Custodian. Until a swap agreement is settled in cash, the gain or loss on the notional amount less any transaction costs or trading spreads payable by each Fund on the notional amount are recorded as “unrealized appreciation or depreciation on swap agreements” and, when cash is exchanged, the gain or loss realized is recorded as “realized gains or losses on swap agreements.” Swap agreements are generally valued at the last settled price of the benchmark referenced asset.

Swap agreements contain various conditions, events of default, termination events, covenants and representations. The triggering of certain events or the default on certain terms of the agreement could allow a party to terminate a transaction under the agreement and request immediate payment in an amount equal to the net positions owed the party under the agreement. This could cause a Fund to have to enter into a new transaction with the same counterparty, enter in to a transaction with a different counterparty or seek to achieve its investment objective through any number of different investments or investment techniques.

Swap agreements involve, to varying degrees, elements of market risk and exposure to loss in excess of the unrealized gain/loss reflected. The notional amounts reflect the extent of the total investment exposure each Fund has under the swap agreement, which may exceed the NAV of each Fund. Additional risks associated with the use of swap agreements are imperfect correlations between movements in the notional amount and the price of the underlying reference index and the inability of counterparties to perform. Each Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. A Fund will typically enter into swap agreements only with major global financial institutions. The creditworthiness of each of the firms that is a party to a swap agreement is monitored by the Sponsor. The Sponsor may use various techniques to minimize credit risk including early termination and payment, using different counterparties, limiting the net amount due from any individual counterparty and generally requiring collateral to be posted by the counterparty in an amount approximately equal to that owed to the Funds. All of the outstanding swap agreements at June 30, 2018 contractually terminate within one month but may be terminated without penalty by either party daily. Upon termination, the Fund is entitled to pay or receive the “unrealized appreciation or depreciation” amount.

The Funds, as applicable, collateralize swap agreements by segregating or designating cash and/or certain securities as indicated on the Statements of Financial Condition or Schedules of Investments. As noted above, collateral posted in connection with uncleared derivative transactions is held for the benefit of the counterparty in a segregated tri-party account at the Custodian to protect the counterparty against non-payment by the Funds. The collateral held in this account is restricted as to its use. In the event of a default by the counterparty, the Funds will seek withdrawal of this collateral from the segregated account and may incur certain costs in exercising its right with respect to the collateral. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Funds may experience significant delays in obtaining any recovery in a bankruptcy or other reorganizational proceeding. The Funds may obtain only limited recovery or may obtain no recovery in such circumstances.

The Funds remain subject to credit risk with respect to the amount they expect to receive from counterparties. However, the Funds have sought to mitigate these risks in connection with uncleared swaps by generally requiring that the counterparties for each Fund agree to post collateral for the benefit of the Fund, marked to market daily, in an amount approximately equal to what the counterparty owes the Fund, subject to certain minimum thresholds. In the event of the bankruptcy of a counterparty, such Fund will have direct access to the collateral received from the counterparty, generally as of the day prior to the bankruptcy, because there is a one day time lag between the Fund’s request for collateral and the delivery of such collateral. To the extent any such collateral is insufficient, the Funds will be exposed to counterparty risk as described above, including the possible delays in recovering amounts as a result of bankruptcy proceedings. As of June 30, 2018, the collateral posted by counterparties consisted of cash and/or U.S. Treasury securities.

The counterparty/credit risk for cleared derivative transactions is generally lower than for uncleared OTC derivatives since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries.

Forward Contracts

Certain of the Funds enter into forward contracts for purposes of pursuing their investment objectives and as a substitute for investing directly in (or shorting) commodities and/or currencies. A forward contract is an agreement between two parties to purchase or sell a specified quantity of an asset at or before a specified date in the future at a specified price. Forward contracts are typically traded in OTC markets and all details of the contracts are negotiated between the counterparties to the agreement. Accordingly, the forward contracts are valued by reference to the contracts traded in the OTC markets.

The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or currency, establishing an opposite position in the contract and recognizing the profit or loss on both positions simultaneously on the delivery date or, in some instances, paying a cash settlement before the designated date of delivery. The forward contracts are adjusted by the daily fluctuation of the underlying commodity or currency and any gains or losses are recorded for financial statement purposes as unrealized gains or losses until the contract settlement date.

Forward contracts have traditionally not been cleared or guaranteed by a third party. As a result of the Dodd-Frank Act, the CFTC now regulates non-deliverable forwards (including deliverable forwards where the parties do not take delivery). Certain non-deliverable forward contracts, such as non-deliverable foreign exchange forwards, may be subject to regulation as swap agreements, including mandatory clearing. Changes in the forward markets may entail increased costs and result in burdensome reporting requirements.

The Funds may collateralize uncleared forward commodity contracts by segregating or designating cash and/or certain securities as indicated on their Statements of Financial Condition or Schedules of Investments. Such collateral is held for the benefit of the counterparty in a segregated tri-party account at the Custodian to protect the counterparty against non-payment by the Funds. The collateral held in this account is restricted as to its use. In the event of a default by the counterparty, the Funds will seek withdrawal of this collateral from the segregated account and may incur certain costs in exercising its right with respect to the collateral. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, the Funds may experience significant delays in obtaining any recovery in a bankruptcy or other reorganizational proceeding. The Funds may obtain only limited recovery or may obtain no recovery in such circumstances.

The Funds remain subject to credit risk with respect to the amount they expect to receive from counterparties. However, the Funds have sought to mitigate these risks by generally requiring that the counterparties for each Fund agree to post collateral for the benefit of the Fund, marked to market daily, in an amount approximately equal to what the counterparty owes the Fund, subject to minimum thresholds. In the event of the bankruptcy of a counterparty, the Fund will have direct access to the collateral received from the counterparty, generally as of the day prior to the bankruptcy, because there is a one day time lag between the Fund’s request for collateral and the delivery of such collateral. To the extent any such collateral is insufficient, the Fund will be exposed to counterparty risk as described above, including the possible delays in recovering amounts as a result of bankruptcy proceedings. As of June 30, 2018, the collateral posted by counterparties consisted of cash and/or U.S. Treasury securities.

Participants in trading foreign exchange forward contracts often do not require margin deposits, but rely upon internal credit limitations and their judgments regarding the creditworthiness of their counterparties. In recent years, however, many OTC market participants in foreign exchange trading have begun to require their counterparties to post margin.

A Fund will typically enter into forward contracts only with major global financial institutions. The creditworthiness of each of the firms that is a party to a forward contract is monitored by the Sponsor.

The counterparty/credit risk for cleared derivative transactions is generally lower than for uncleared OTC derivatives since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries.

Offsetting Assets and Liabilities

Each Fund is subject to master netting agreements or similar arrangements that allow for amounts owed between each Fund and the counterparty to be netted upon an early termination. The party that has the larger payable pays the excess of the larger amount over the smaller amount to the other party. The master netting agreements or similar arrangements do not apply to amounts owed to/from different counterparties. As described above, the Funds utilize derivative instruments to achieve their investment objective during the year. The amounts shown in the Statements of Financial Condition do not take into consideration the effects of legally enforceable master netting agreements or similar arrangements.

For financial reporting purposes, the Funds do not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statements of Financial Condition. The following table presents each Fund’s derivatives by investment type and by counterparty net of amounts available for offset under a master netting agreement and the related collateral received or pledged by the Funds as of June 30, 2018.

Asset (Liability) amounts shown in the table below represent amounts owed to (by) the Funds for the derivative-related investments at June 30, 2018. These amounts may be collateralized by cash or financial instruments, segregated for the benefit of the Funds or the counterparties, depending on whether the related contracts are in an appreciated or depreciated position at period end. Amounts shown in the column labeled “Net Amount” represent the uncollateralized portions of these amounts at period end. These amounts may be un-collateralized due to timing differences related to market movements or due to minimum thresholds for collateral movement, as further described above under the caption “Accounting for Derivative Instruments”.

Agreements

NOTE 4 – AGREEMENTS

Management Fee

Each Leveraged Fund, the Short Euro Fund and each Geared VIX Fund pays the Sponsor a Management Fee, monthly in arrears, in an amount equal to 0.95% per annum of its average daily NAV of such Fund. Each Matching VIX Fund pays the Sponsor a Management Fee, monthly in arrears, in an amount equal to 0.85% per annum of its average daily NAV of such Fund. The Sponsor has not and will not charge a Management Fee in each of the Fund’s first year of operations in an amount equal to the offering costs. The Sponsor has reimbursed and will reimburse each Fund, to the extent that its offering costs exceed the Management Fee, for the first year of operations.

The Management Fee is paid in consideration of the Sponsor’s trading advisory services and the other services provided to the Fund that the Sponsor pays directly. From the Management Fee, the Sponsor pays all of the routine operational, administrative and other ordinary expenses of each Fund, generally as determined by the Sponsor, including but not limited to the Administrator, Custodian, Distributor, ProFunds Distributors, Inc. (“PDI”), an affiliated broker-dealer of the Sponsor, Transfer Agent, accounting and auditing fees and expenses, any index licensors for the Funds, and the normal and expected expenses incurred in connection with the continuous offering of Shares of each Fund after the commencement of its trading operations, including, but not limited to, expenses such as tax preparation expenses, legal fees not in excess of $100,000 per annum, ongoing SEC registration fees not exceeding 0.021% per annum of the NAV of a Fund and Financial Industry Regulatory Authority (“FINRA”) filing fees, individual ScheduleK-1 preparation and mailing fees not exceeding 0.10% per annum of the net assets of a Fund, and report preparation and mailing expenses.

Non-Recurring Fees and Expenses

Each Fund pays all its non-recurring and unusual fees and expenses, if any, as determined by the Sponsor. Non-recurring and unusual fees and expenses are fees and expenses that are unexpected or unusual in nature, such as legal claims and liabilities, litigation costs or indemnification or other material expenses which are not currently anticipated obligations of the Funds.

The Administrator

The Sponsor and the Trust, for itself and on behalf of each Fund, has appointed Brown Brothers Harriman & Co. (“BBH&Co.”) as the Administrator of the Funds, and the Sponsor, and the Trust, on its own behalf and on behalf of each Fund, and BBH&Co. have entered into an Administrative Agency Agreement (the “Administration Agreement”) in connection therewith. Pursuant to the terms of the Administration Agreement and under the supervision and direction of the Sponsor and the Trust, BBH&Co. prepares and files certain regulatory filings on behalf of the Funds. BBH&Co. may also perform other services for the Funds pursuant to the Administration Agreement as mutually agreed upon by the Sponsor, the Trust and BBH&Co. from time to time. Pursuant to the terms of the Administration Agreement, BBH&Co. also serves as the Transfer Agent of the Funds. The Administrator’s fees are paid on behalf of the Funds by the Sponsor.

The Custodian

BBH&Co. serves as the Custodian of the Funds, and the Trust, on its own behalf and on behalf of each Fund, and BBH&Co. have entered into a Custodian Agreement in connection therewith. Pursuant to the terms of the Custodian Agreement, BBH&Co. is responsible for the holding and safekeeping of assets delivered to it by the Funds, and performing various administrative duties in accordance with instructions delivered to BBH&Co. by the Funds. The Custodian’s fees are paid on behalf of the Funds by the Sponsor.

The Distributor

SEI Investments Distribution Co. (“SEI”), serves as Distributor of the Funds and assists the Sponsor and the Administrator with certain functions and duties relating to distribution and marketing, including taking creation and redemption orders, consulting with the marketing staff of the Sponsor and its affiliates with respect to compliance with the requirements of FINRA and/or the NFA in connection with marketing efforts, and reviewing and filing of marketing materials with FINRA and/or the NFA. SEI retains all marketing materials separately for each Fund, at c/o SEI, One Freedom Valley Drive, Oaks, PA 19456. The Sponsor, on behalf of each Fund, has entered into a Distribution Services Agreement with SEI. The Sponsor pays SEI for performing its duties on behalf of the Funds.

Creation and Redemption of Creation Units

Text Block [Abstract]

Creation and Redemption of Creation Units

NOTE 6 – CREATION AND REDEMPTION OF CREATION UNITS

Each Fund issues and redeems shares from time to time, but only in one or more Creation Units. A Creation Unit is a block of 50,000 Shares of a Geared Fund and 25,000 Shares of a Matching VIX Fund. Creation Units may be created or redeemed only by Authorized Participants. As a result of the Share splits and reverse Share splits as described in Note 1, certain redemptions as disclosed in the Statements of Changes in Shareholders’ Equity reflect payment of fractional share balances on beneficial shareholder accounts.

Except when aggregated in Creation Units, the Shares are not redeemable securities. Retail investors, therefore, generally will not be able to purchase or redeem Shares directly from or with a Fund. Rather, most retail investors will purchase or sell Shares in the secondary market with the assistance of a broker. Thus, some of the information contained in these Notes to Financial Statements—such as references to the Transaction Fees imposed on purchases and redemptions is not relevant to retail investors.

Transaction Fees on Creation and Redemption Transactions

The manner by which Creation Units are purchased or redeemed is governed by the terms of the Authorized Participant Agreement and Authorized Participant Handbook. By placing a purchase order, an Authorized Participant agrees to: (1) deposit cash with the Custodian; and (2) if permitted by the Sponsor in its sole discretion, enter into or arrange for an exchange of futures contract for related position or block trade with the relevant fund whereby the Authorized Participant would also transfer to such Fund a number and type of exchange-traded futures contracts at or near the closing settlement price for such contracts on the purchase order date.

Authorized Participants may pay a fixed transaction fee of up to $250 in connection with each order to create or redeem a Creation Unit in order to compensate BBH&Co., as the Administrator, the Custodian and the Transfer Agent of each Fund and its Shares, for services in processing the creation and redemption of Creation Units and to offset the costs of increasing or decreasing derivative positions. Authorized Participants also may pay a variable transaction fee to the Fund of up to 0.10% (and a variable transaction fee to the Matching VIX Funds of 0.05%) of the value of the Creation Unit that is purchased or redeemed unless the transaction fee is waived or otherwise adjusted by the Sponsor. The Sponsor provides such Authorized Participant with prompt notice in advance of any such waiver or adjustment of the transaction fee.

Risks and Uncertainties [Abstract]

Risk

NOTE 8 – RISK

Correlation and Compounding Risk

The Geared Funds do not seek to achieve their stated investment objective over a period of time greater than a single day (as measured from NAV calculation time to NAV calculation time). The return of a Geared Fund for a period longer than a single day is the result of its return for each day compounded over the period and usually will differ from the one-half inverse (-0.5x), the inverse (-1x), two times the inverse (-2x), one and one-half times (1.5x) of the return, two times (2x) of the return, three times the inverse (-3x), or three times of the return (3x) of the Geared Fund’s benchmark for the period. A Geared Fund will lose money if its benchmark performance is flat over time, and it is possible for a Geared Fund to lose money over time even if the performance of its benchmark increases (or decreases in the case of Short, UltraShort and UltraPro Short Funds), as a result of daily rebalancing, the benchmark’s volatility, compounding, and other factors. Longer holding periods, higher benchmark volatility, inverse exposure and greater leverage each affect the impact of compounding on a Geared Fund’s returns. Daily compounding of a Geared Fund’s investment returns can dramatically and adversely affect its longer-term performance during periods of high volatility. Volatility may be at least as important to a Geared Fund’s return fora period as the return of the Geared Fund’s underlying benchmark. The Matching VIX Funds seek to achieve their stated investment objective over time.

Each Ultra, UltraShort, UltraPro and UltraPro Short Fund uses leverage and should produce daily returns that are more volatile than that of its benchmark. For example, the daily return of an Ultra or UltraPro Fund with a 1.5x or 2x or 3x multiple should be approximately one and one-half or two or three times as volatile on a daily basis as is the return of a fund with an objective of matching the same benchmark. The daily return of an UltraShort or UltraPro Short Fund is designed to return two times the inverse (-2x) or three times the inverse (-3x) of the return that would be expected of a fund with an objective of matching the same benchmark. The Geared Funds are not appropriate for all investors and present significant risks not applicable to other types funds. The Leveraged Funds use leverage and are riskier than similarly benchmarked exchange-traded funds that do not use leverage. An investor should only consider an investment in a Geared Fund if he or she understands the consequences of seeking daily leveraged, daily inverse or daily inverse leveraged investment results. Shareholders who invest in the Funds should actively manage and monitor their investments, as frequently as daily.

While the Funds seek to meet their investment objectives, there is no guarantee they will do so. Factors that may affect a Fund’s ability to meet its investment objective include: (1) the Sponsor’s ability to purchase and sell Financial Instruments in a manner that correlates to a Fund’s objective; (2) an imperfect correlation between the performance of Financial Instruments held by a Fund and the performance of the applicable benchmark; (3) bid-ask spreads on such Financial Instruments; (4) fees, expenses, transaction costs, financing costs associated with the use of Financial Instruments and commission costs; (5) holding or trading instruments in a market that has become illiquid or disrupted; (6) a Fund’s Share prices being rounded to the nearest cent and/or valuation methodology; (7) changes to a benchmark index that are not disseminated in advance; (8) the need to conform a Fund’s portfolio holdings to comply with investment restrictions or policies or regulatory or tax law requirements; (9) early and unanticipated closings of the markets on which the holdings of a Fund trade, resulting in the inability of the Fund to execute intended portfolio transactions; (10) accounting standards; and (11) differences caused by a Fund obtaining exposure to only a representative sample of the components of a benchmark, over weighting or under weighting certain components of a benchmark or obtaining exposure to assets that are not included in a benchmark.

A number of factors may affect a Geared Fund’s ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that a Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent a Geared Fund from achieving its investment objective. In order to achieve a high degree of correlation with their underlying benchmarks, the Geared Funds seek to rebalance their portfolios daily to keep exposure consistent with their investment objectives. Being materially under- or over-exposed to the benchmark may prevent such Geared Funds from achieving a high degree of correlation with such benchmark. Market disruptions or closure, large amounts of assets into or out of the Geared Funds, regulatory restrictions, extreme market volatility, and other factors will adversely affect such Funds’ ability to adjust exposure to requisite levels. The target amount of portfolio exposure is impacted dynamically by the benchmarks’ movements during each day. Because of this, it is unlikely that the Geared Funds will be perfectly exposed (i.e., -0.5x, -1x, -2x, 1.5x, 2x, -3x or 3x as applicable) to its benchmark at the end of each day, and the likelihood of being materially under- or over-exposed is higher on days when the benchmark levels are volatile near the close of the trading day.

Each Geared Fund seeks to rebalance its portfolio on a daily basis. The time and manner in which a Geared Fund rebalances its portfolio may vary from day to day depending upon market conditions and other circumstances at the discretion of the Sponsor. Unlike other funds that do not rebalance their portfolios as frequently, each Geared Fund may be subject to increased trading costs associated with daily portfolio rebalancing in order to maintain appropriate exposure to the underlying benchmarks.

Counterparty Risk

Each Fund may use derivatives such as swap agreements and forward contracts (collectively referred to herein as “derivatives”) in the manner described herein as a means to achieve their respective investment objectives. The use of derivatives by a Fund exposes the Fund to counterparty risks.

Regulatory Treatment

Derivatives are generally traded in over-the-counter (“OTC”) markets and have only recently become subject to comprehensive regulation in the United States. Cash-settled forwards are generally regulated as “swaps”, whereas physically settled forwards are generally not subject to regulation (in the case of commodities other than currencies) or subject to the federal securities laws (in the case of securities).

Title VII of the Dodd-Frank Act (“Title VII”) created a regulatory regime for derivatives, with the CFTC responsible for the regulation of swaps and the SEC responsible for the regulation of “security-based swaps.” The SEC requirements have largely yet to be made effective, but the CFTC requirements are largely in place. The CFTC requirements have included rules for some of the types of transactions in which the Funds will engage, including mandatory clearing and exchange trading, reporting, and margin for uncleared swaps. Title VII also created new categories of regulated market participants, such as “swap dealers,” “security-based swap dealers,” “major swap participants,” and “major security-based swap participants” who are, or will be, subject to significant new capital,

registration, recordkeeping, reporting, disclosure, business conduct and other regulatory requirements. The regulatory requirements under Title VII continue to be developed and there may be further modifications that could impact the Funds.

As noted, the CFTC rules may not apply to all of the swap agreements and forward contracts entered into by the Funds. Investors, therefore, may not receive the protection of CFTC regulation or the statutory scheme of the CEA in connection with each Fund’s swap agreements or forward contracts. The lack of regulation in these markets could expose investors to significant losses under certain circumstances, including in the event of trading abuses or financial failure by participants.

Counterparty Credit Risk

The Funds will be subject to the credit risk of the counterparties to the derivatives. In the case of cleared derivatives, the Funds will have credit risk to the clearing corporation in a similar manner as the Funds would for futures contracts. In the case of uncleared derivatives, the Funds will be subject to the credit risk of the counterparty to the transaction – typically a single bank or financial institution. As a result, a Fund is subject to increased credit risk with respect to the amount it expects to receive from counterparties to uncleared derivatives entered into as part of that Fund’s principal investment strategy. If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, a Fund could suffer significant losses on these contracts and the value of an

investor’s investment in a Fund may decline.

The Funds have sought to mitigate these risks by generally requiring that the counterparties for each Fund agree to post collateral for the benefit of the Fund, marked to market daily, subject to certain minimum thresholds. However, there are no limitations on the percentage of assets each Fund may invest in swap agreements or forward contracts with a particular counterparty. To the extent any such collateral is insufficient or there are delays in accessing the collateral, the Funds will be exposed to counterparty risk as described above, including possible delays in recovering amounts as a result of bankruptcy proceedings. The Funds typically enter into transactions only with major, global financial institutions.

OTC derivatives of the type that may be utilized by the Funds are generally less liquid than futures contracts because they are not traded on an exchange, do not have uniform terms and conditions, and are generally entered into based upon the creditworthiness of the parties and the availability of credit support, such as collateral, and in general, are not transferable without the consent of the counterparty. These agreements contain various conditions, events of default, termination events, covenants and representations. The triggering of certain events or the default on certain terms of the agreement could allow a party to terminate a transaction under the agreement and request immediate payment in an amount equal to the net positions owed to the party under the agreement. For example, if the level of the Fund’s benchmark has a dramatic intraday move that would cause a material decline in the Fund’s NAV, the terms of the swap may permit the counterparty to immediately close out the transaction with the Fund. In that event, it may not be possible for the Fund to enter into another swap or to invest in other Financial Instruments necessary to achieve the desired exposure consistent with the Fund’s objective. This, in turn, may prevent the Fund from achieving its investment objective, particularly if the level of the Fund’s benchmark reverses all or part of its intraday move by the end of the day.

In addition, cleared derivatives benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. To the extent the Fund enters into cleared swap transactions, the Fund will deposit collateral with an FCM in cleared swaps customer accounts, which are required by CFTC regulations to be separate from its proprietary collateral posted for cleared swaps transactions. Cleared swap customer collateral is subject to regulations that closely parallel the regulations governing customer segregated funds for futures transactions but provide certain additional protections to cleared swaps collateral in the event of a clearing broker or clearing broker customer default. For example, in the event of a default of both the clearing broker and a customer of the clearing broker, a clearing house is only permitted to access the cleared swaps collateral in the legally separate (but operationally comingled) account of the defaulting cleared swap customer of the clearing broker, as opposed to the treatment of customer segregated funds, under which the clearing house may access all of the commingled customer segregated funds of a defaulting clearing broker. Uncleared derivatives entered into directly between two counterparties do not necessarily benefit from such protections, particularly if entered into with an entity that is not registered as a “swap dealer” with the CFTC. This exposes the Funds to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Funds to suffer a loss.

The Sponsor regularly reviews the performance of its counterparties for, among other things, creditworthiness and execution quality. In addition, the Sponsor periodically considers the addition of new counterparties and the counterparties used by a Fund may change at any time. Each day, the Funds disclose their portfolio holdings as of the prior Business Day. Each Fund’s portfolio holdings identifies its counterparties, as applicable. This portfolio holdings information may be accessed through the web on the Sponsor’s website at www.ProShares.com.

Each counterparty and/or any of its affiliates may be an Authorized Participant or shareholder of a Fund, subject to applicable law.

The counterparty risk for cleared derivatives transactions is generally lower than for uncleared OTC derivatives. Once a transaction is cleared, the clearing organization is substituted and is a Fund’s counterparty on the derivative. The clearing organization guarantees the performance of the other side of the derivative. Nevertheless, some risk remains, as there is no assurance that the clearing organization, or its members, will satisfy its obligations to a Fund.

Leverage Risk

The Leveraged Funds may utilize leverage in seeking to achieve their respective investment objectives and will lose more money in market environments adverse to their respective daily investment objectives than funds that do not employ leverage. The use of leveraged and/or inverse leveraged positions could result in the total loss of an investor’s investment, even over periods as short as a single day.

For example, because the UltraShort Funds and Ultra Funds (except for the Ultra VIX Short-Term Futures ETF which includes a one and one-half times multiplier) include a two times the inverse (-2x), or a two times (2x) multiplier, a single-day movement in the relevant benchmark approaching 50% at any point in the day could result in the total loss or almost total loss of an investor’s investment if that movement is contrary to the investment objective of the Fund in which an investor has invested, even if such Fund’s benchmark subsequently moves in an opposite direction, eliminating all or a portion of the movement. For UltraPro Fund and UltraPro Short Fund, because the Funds include a three times (3x) or three times the inverse (-3x) multiplier, a single day movement in the benchmark approaching 33% at any point in the day could result in the total loss or almost total loss of an investor’s investment if that movement is contrary to the investment objective of the Fund in which an investor has invested, even if the benchmark subsequently moves in an opposite direction, eliminating all or a portion of the movement. This would be the case with downward single-day or intraday movements in the underlying benchmark of an Ultra Fund and UltraPro Fund or upward single-day or intraday movements in the benchmark of an UltraShort Fund and UltraPro Short Fund, even if the underlying benchmark maintains a level greater than zero at all times.

Liquidity Risk

Financial Instruments cannot always be liquidated at the desired price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A market disruption can also make it difficult to liquidate a position or find a swap or forward contract counterparty at a reasonable cost. Market illiquidity may cause losses for the Funds. The large size of the positions which the Funds may acquire increases the risk of illiquidity by both making their positions more difficult to liquidate and increasing the losses incurred while trying to do so. Any type of disruption or illiquidity will potentially be exacerbated due to the fact that the Funds will typically invest in Financial Instruments related to one benchmark, which in many cases is highly concentrated.

“Contango” and “Backwardation” Risk

In Funds that hold futures contracts, as the futures contracts near expiration, they are generally replaced by contracts that have a later expiration. Thus, for example, a contract purchased and held in November 2017 may specify a January 2018 expiration. As that contract nears expiration, it may be replaced by selling the January 2018 contract and purchasing the contract expiring in March 2018. This process is referred to as “rolling.” Rolling may have a positive or negative impact on performance. For example, historically, the prices of certain types of futures contracts have frequently been higher for contracts with shorter-term expirations than for contracts with longer-term expirations, which is referred to as “backwardation.” In these circumstances, absent other factors, the sale of the January

2018 contract would take place at a price that is higher than the price at which the March 2018 contract is purchased, thereby creating a gain in connection with rolling. While certain types of futures contracts have historically exhibited consistent periods of backwardation, backwardation will likely not exist in these markets at all times. The presence of contango (where prices of contracts are higher in the distant delivery months than in the nearer delivery months due to the costs of long-term storage of a physical commodity prior to delivery or other factors) in certain futures contracts at the time of rolling would be expected to adversely affect an Ultra Fund, an UltraPro Fund or a Matching VIX Fund that invests in such futures, and positively affect a Short Fund, an UltraShort Fund or an UltraPro Short Fund that invests in such futures. Similarly, the presence of backwardation in certain futures contracts at the time of rolling such contracts would be expected to adversely affect the Short Funds, UltraShort Funds, and UltraPro Short Funds, and positively affect the Ultra Funds, UltraPro Funds and Matching VIX Funds.

Since the introduction of VIX futures contracts, there have frequently been periods where VIX futures prices reflect higher expected volatility levels further out in time. This can result in a loss from “rolling” the VIX futures to maintain the constant weighted average maturity of the applicable VIX Futures Index. Losses from exchanging a lower priced VIX future for a higher priced longer-term future in the rolling process would adversely affect the value of each VIX Futures Index and, accordingly, decrease the return of the Ultra VIX Short-Term Futures ETF and the Matching VIX Funds.

Gold and silver have historically exhibited persistent “contango” markets rather than backwardation. Natural gas, like crude oil, moves in and out of backwardation and contango but historically has been in contango most commonly.

Accounting Policies [Abstract]

Use of Estimates & Indemnifications

Use of Estimates & Indemnifications

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

In the normal course of business, the Trust enters into contracts that contain a variety of representations which provide general indemnifications. The Trust’s maximum exposure under these arrangements cannot be known; however, the Trust expects any risk of loss to be remote.

Basis of Presentation

Basis of Presentation

Pursuant to rules and regulations of the SEC, audited financial statements are presented for the Trust as a whole, as the SEC registrant, and for each Fund individually. The debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to a particular Fund shall be enforceable only against the assets of such Fund and not against the assets of the Trust generally or any other Fund. Accordingly, the assets of one Fund of the Trust include only those funds and other assets that are paid to, held by or distributed to the Trust for the purchase of Shares in that Fund.

Statement of Cash Flows

Statement of Cash Flows

The cash amount shown in the Statements of Cash Flows is the amount reported as cash in the Statement of Financial Condition dated June 30, 2018, and represents cash, segregated cash balances with brokers for futures contracts, segregated cash with brokers for swap agreements, segregated cash with brokers for forward agreements, and segregated cash with brokers for foreign currency forward agreements but does not include short-term investments.

* Although the Funds’ shares may continue to trade on secondary markets subsequent to the calculation of the final NAV, these times represent the final opportunity to transact in creation or redemption units for the six months ended June 30, 2018.

Market value per Share is determined at the close of the NYSE Arca and may be later than when the Funds’ NAV per Share is calculated.

For financial reporting purposes, the Funds value transactions based upon the final closing price in their primary markets. Accordingly, the investment valuations in these financial statements may differ from those used in the calculation of certain of the Funds’ final creation/redemption NAV for the six months ended June 30, 2018.

Investment Valuation

Investment Valuation

Short-term investments are valued at amortized cost which approximates fair value for daily NAV purposes. For financial reporting purposes, short-term investments are valued at their market price using information provided by a third-party pricing service or market quotations. In each of these situations, valuations are typically categorized as Level I in the fair value hierarchy.

Derivatives (e.g., futures contracts, swap agreements, forward agreements and foreign currency forward contracts) are typically valued using independent sources and/or agreements with counterparties or other procedures as determined by the Sponsor. Futures contracts, except for those entered into by the Gold, Silver, Australian Dollar and Short Euro Funds, are typically valued at the last settled price on the applicable exchange on which that future trades. Futures contracts entered into by the Gold, Silver, Australian Dollar and Short Euro Funds are typically valued at the last sales price prior to the time at which the NAV per Share of a Fund is determined. For financial reporting purposes, all futures contracts are typically valued at the last settled price. Futures contracts valuations are typically categorized as Level I in the fair value hierarchy. Swap agreements, forward agreements and foreign currency forward contracts valuations are typically categorized as Level II in the fair value hierarchy. The Sponsor may in its sole discretion choose to determine a fair value price as the basis for determining the market value of such position. Such fair value prices would generally be determined based on available inputs about the current value of the underlying financial instrument or commodity and would be based on principles that the Sponsor deems fair and equitable so long as such principles are consistent with industry standards. The Sponsor may fair value an asset of a Fund pursuant to the policies the Sponsor has adopted, which are consistent with normal industry standards. Depending on the source and relevant significance of valuation inputs, these instruments may be classified as Level II or Level III in the fair value hierarchy.

Fair value pricing may require subjective determinations about the value of an investment. While the Funds’ policies are intended to result in a calculation of its respective Fund’s NAV that fairly reflects investment values as of the time of pricing, such Fund cannot ensure that fair values determined by the Sponsor or persons acting at their direction would accurately reflect the price that a Fund could obtain for an investment if it were to dispose of that investment as of the time of pricing (for instance, in a forced or distressed sale). The prices used by such Fund may differ from the value that would be realized if the investments were sold and the differences could be material to the financial statements.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The Funds disclose the fair value of their investments in a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The disclosure requirements establish a fair value hierarchy that distinguishes between: (1) market participant assumptions developed based on market data obtained from sources independent of the Funds (observable inputs); and (2) the Funds’ own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the disclosure requirements hierarchy are as follows:

Level I – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level II – Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level II assets include the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs).

Level III – Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available.

In some instances, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest input level that is significant to the fair value measurement in its entirety.

Fair value measurements also require additional disclosure when the volume and level of activity for the asset or liability have significantly decreased, as well as when circumstances indicate that a transaction is not orderly.

Investment Transactions and Related Income

Investment Transactions and Related Income

Investment transactions are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized appreciation/depreciation on open contracts are reflected in the Statements of Financial Condition and changes in the unrealized appreciation/depreciation between periods are reflected in the Statements of Operations. Discounts on short-term securities purchased are amortized and reflected as Interest Income in the Statements of Operations.

Brokerage Commissions and Fees

Brokerage Commissions and Fees

Each Fund pays its respective brokerage commissions, including applicable exchange fees, National Futures Association (“NFA”) fees, give-up fees, pit brokerage fees and other transaction related fees and expenses charged in connection with trading activities for each Fund’s investment in U.S. Commodity Futures Trading Commission (“CFTC”) regulated investments. The effects of trading spreads, financing costs/fees associated with Financial Instruments, and costs relating to the purchase of U.S. Treasury securities or similar high credit quality short-term fixed-income would also be borne by the Funds. Brokerage commissions on futures contracts are recognized on a half-turn basis (e.g., the first half is recognized when the contract is purchased (opened) and the second half is recognized when the transaction is closed). The Sponsor is currently paying brokerage commissions on VIX futures contracts for the Matching VIX Funds that exceed variable create/redeem fees collected by more than 0.02% of the Matching VIX Fund’s average net assets annually.

Federal Income Tax

Federal Income Tax

Each Fund is registered as a series of a Delaware statutory trust and is treated as a partnership for U.S. federal income tax purposes. Accordingly, no Fund expects to incur U.S. federal income tax liability; rather, each beneficial owner of a Fund’s Shares is required to take into account its allocable share of its Fund’s income, gain, loss, deductions and other items for its Fund’s taxable year ending with or within the beneficial owner’s taxable year.

Management of the Funds has reviewed all open tax years and major jurisdictions (i.e., the last four tax year ends and the interim tax period since then, as applicable) and concluded that there is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken in future tax returns. The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. On an ongoing basis, management will monitor its tax positions taken under the interpretation to determine if adjustments to conclusions are necessary based on factors including, but not limited to, on-going analysis of tax law, regulation, and interpretations thereof.

New Accounting Pronouncements

New Accounting Pronouncements

In November 2016, the FASB issued Accounting Standards Update No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash” (“ASU 2016-18”), which amends ASC 230 to provide guidance on the classification and presentation of changes in restricted cash and restricted cash equivalents on the statement of cash flows. The ASU has been adopted for the current reporting period under the retrospective transition method. The adoption had no significant impact to the Statement of Cash Flows.

At June 30, 2018, there were no Level III portfolio investments for which significant unobservable inputs were used to determine fair value.

The Funds’ policy is to recognize transfers between valuation levels at the end of the reporting period.

At June 30, 2018, there were no significant transfers in or out of Level I and Level II fair value measurements.

The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those securities.

The following table summarizes the valuation of investments at December 31, 2017 using the fair value hierarchy:

Gross Amounts Not Offset in Statements of Financial Condition

Asset (Liability) amounts shown in the table below represent amounts owed to (by) the Funds for the derivative-related investments at June 30, 2018. These amounts may be collateralized by cash or financial instruments, segregated for the benefit of the Funds or the counterparties, depending on whether the related contracts are in an appreciated or depreciated position at period end. Amounts shown in the column labeled “Net Amount” represent the uncollateralized portions of these amounts at period end. These amounts may be un-collateralized due to timing differences related to market movements or due to minimum thresholds for collateral movement, as further described above under the caption “Accounting for Derivative Instruments”.
