NOTES TO FINANCIAL STATEMENTS

March 31, 2016

(unaudited)

NOTE 1 – ORGANIZATION

ProShares Trust II (formerly known as the Commodities and Currencies Trust) (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 March 31, 2016, 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”); and (iii) ProShares UltraShort Bloomberg Commodity, ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Bloomberg Natural Gas, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Australian Dollar, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Commodity, ProShares Ultra Bloomberg Crude Oil, 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.

On May 22, 2015, the Trust announced plans to liquidate ProShares Ultra Australian Dollar (ticker symbol: GDAY). ProShares Ultra Australian Dollar was closed to purchases and redemptions as of the close of regular trading on the NYSE Arca on June 18, 2015. Beginning June 19, 2015, no secondary market for ProShares Ultra Australian Dollar’s Shares remained. Proceeds of the liquidation were distributed to shareholders on June 29, 2015. Any shareholders remaining in the fund on June 29, 2015 automatically had their shares redeemed for cash at ProShares Ultra Australian Dollar’s net asset value per Share as of June 19, 2015. On June 30, 2015, the NYSE Arca filed a Form 25 removing the listing of ProShares Ultra Australian Dollar on the NYSE Arca. On July 10, 2015 a Form 15 was filed with the U.S. Securities and Exchange Commission (“SEC”) terminating the registration of ProShares Ultra Australian Dollar.

On February 18, 2016, the Trust announced plans to liquidate ProShares Managed Futures Strategy (ticker symbol: FUTS). ProShares Managed Futures Strategy was closed to purchases and redemptions as of the close of regular trading on the NYSE Arca on March 18, 2016. Beginning March 21, 2016, no secondary market for ProShares Managed Futures Strategy’s Shares remained. Proceeds of the liquidation were distributed to shareholders on March 30, 2016. Any shareholders remaining in the fund on March 30, 2016 automatically had their shares redeemed for cash at ProShares Managed Futures Strategy’s net asset value per Share as of March 21, 2016. On March 31, 2016, the NYSE Arca filed a Form 25 removing the listing of ProShares Managed Futures Strategy on the NYSE Arca. On April 11, 2016 a Form 15 was filed with the SEC terminating the registration of ProShares Managed Futures Strategy.

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 Commodity, ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Commodity, 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,” or “Ultra Funds” refer to the different Funds based upon their investment objectives, but without distinguishing among the Funds’ benchmarks.

106

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.

Each “Short” Fund seeks daily investment results (before fees and expenses) that correspond to 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 two times (2x) 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.

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., -1x, -2x or 2x) of the period return of the corresponding benchmark and will likely differ significantly.

The Matching VIX Funds seek to achieve their stated investment objective both over a single day and over time.

Each of the Funds generally invests in Financial Instruments (i.e., instruments whose value is derived from the value of an underlying asset, rate or index, 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 its applicable underlying commodity futures index, commodity, currency exchange rate or equity volatility index. 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, 2015. There were no Share splits or reverse Share splits during the three months ended March 31, 2016. The ticker symbols for these Funds did not change, and each Fund continues to trade on the NYSE Arca.

	Execution Date		Date Trading
	(Prior to Opening		Resumed at Post-
Fund	of Trading)	Type of Split	Split Price
ProShares Ultra VIX Short-Term Futures ETF	May 20, 2015	1-for-5 reverse Share split	May 20, 2015
ProShares UltraShort Silver	November 13, 2015	2-for-1 Share split	November 13, 2015
ProShares Ultra Bloomberg Commodity	May 20, 2015	1-for-4 reverse Share split	May 20, 2015
ProShares Ultra Bloomberg Crude Oil	May 20, 2015	1-for-5 reverse Share split	May 20, 2015
ProShares Ultra Bloomberg Natural Gas	May 20, 2015	1-for-4 reverse Share split	May 20, 2015
ProShares Ultra Yen	May 20, 2015	1-for-4 reverse Share split	May 20, 2015

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”).

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 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 for the year ended December 31, 2015, as filed with the SEC on February 29, 2016.

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 and disclosures in these financial statements. 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 March 31, 2016, and represents non-segregated cash with the custodian and 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 three months ended March 31, 2016 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 three months ended March 31, 2016.

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 three months ended March 31, 2016.

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 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 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. 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 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. 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. 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.

109

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 March 31, 2016 using the fair value hierarchy:

At March 31, 2016, 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 March 31, 2016, 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 or similar securities 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). Through July 30, 2014, the Sponsor paid brokerage commissions on VIX futures contracts for the Matching VIX Funds. On July 31, 2014, the Sponsor began paying, and 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.

112

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.

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 and/or used as collateral for a Fund’s trading in futures and 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.

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 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

113

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 or an Ultra Fund, the Matching VIX Fund or Ultra 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 or an UltraShort Fund, the Short Fund or UltraShort 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

114

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.

The Trust, on behalf of a Fund, may enter into agreements with certain counterparties for derivative transactions. 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 the party under the agreement. This could cause a Fund to have to enter into a new transaction with the same counterparty, enter into 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 March 31, 2016 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. 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, 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 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 March 31, 2016, 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.

115

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 contract 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. 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 March 31, 2016, 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.

116

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 March 31, 2016:

Asset (Liability) amounts shown in the table below represent amounts owed to (by) the Funds for the derivative-related investments at March 31, 2016. 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 did not and will not charge the Management Fee in the first year of operation of each Fund in an amount equal to the offering costs. The Sponsor reimbursed 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 services as commodity pool operator, and for managing the business and affairs of the Funds. 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 and 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 Schedule K-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 which 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. Such fees and expenses are those that are non-recurring, unexpected or unusual in nature.

126

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.

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.

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 dictated 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 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 $500 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.

Transaction fees for the three months ended March 31, 2016, which are included in the Addition and/or Redemption of Shares on the Statements of Changes in Shareholders’ Equity, were as follows:

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 inverse (-1x), two times the inverse (-2x), or two times (2x) of the return of the Geared Fund’s benchmark for the period. A 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 and UltraShort Funds), as a result of daily rebalancing, the benchmark’s volatility and compounding. Longer holding periods, higher benchmark volatility, inverse exposure and greater leverage each affect the impact of compounding on a 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 for a period as the return of the Fund’s underlying benchmark. The Matching VIX Funds seek to achieve their stated investment objective both over a single day and over time.

Each Ultra and UltraShort 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 Fund with a 2x multiple should be approximately two 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 a Short or UltraShort Fund is designed to return the inverse (-1x) or two times the inverse (-2x) 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 different risks than other 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. Daily objective geared funds, if used properly and in conjunction with the investor’s view on the future direction and volatility of the markets, can be useful tools for investors who want to manage their exposure to various markets and market segments and who are willing to monitor and/or periodically rebalance their portfolios. Shareholders who invest in the Funds should actively manage and monitor their investments, as frequently as daily.

While the Funds expect to meet their investment objectives, several factors may affect their ability to do so. Among these factors are: (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 instruments traded 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, overweighting or underweighting 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 or extreme market volatility 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., -1x, -2x or 2x, 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. In addition, 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.

135

Counterparty Risk

Certain of the Funds will use swap agreements and/or forward contracts as a means to achieve their respective investment objectives. Such Funds will use either swap agreements and/or forward contracts referencing their respective benchmarks. These Funds may also invest in other swap agreements or forward contracts if such instruments tend to exhibit trading prices or returns that correlate with the benchmark or a component of the benchmark and will further the investment objective of the Fund. Certain Funds may invest in swap agreements or forward contracts if position accountability rules or position limits are reached with respect to specific futures contracts or the market for a specific futures contract experiences emergencies (e.g., natural disaster, terrorist attack or an act of God) or disruptions (e.g., a trading halt or a flash crash) that prevent the Funds from obtaining the appropriate amount of investment exposure to the affected futures contract or certain other futures contracts. Although unlikely, those Funds, under these circumstances, could have 100% exposure to swap agreements or forward contracts.

Swap agreements and forward contracts are generally traded in OTC markets and have only recently become subject to regulation by the CFTC. CFTC rules, however, do not cover all types of swap agreements and forward contracts. Investors, therefore, may not receive the protection of CFTC regulation or the statutory scheme of the Commodity Exchange Act (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.

The Funds will be subject to credit risk with respect to the counterparties to the derivatives contracts (whether a clearing corporation in the case of cleared instruments or another third party in the case of OTC uncleared instruments). Unlike in futures contracts, the counterparty to uncleared swap agreements or forward contracts is generally a single bank or other financial institution, rather than a clearing organization backed by a group of financial institutions. As a result, a Fund is subject to credit risk with respect to the amount it expects to receive from counterparties to uncleared swaps and forward contracts 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 its 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 swaps or forward contracts are 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. 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 agreement 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 derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. Transactions entered into directly between two counterparties generally do not benefit from such protections. 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.

Each counterparty and/or any of its affiliates may be an Authorized Participant or shareholder of a Fund.

136

The counterparty 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 house for performance of financial obligations. However, there can be no assurance that the clearing house, or its members, will satisfy its obligations to the 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.

For example, because the UltraShort Funds and Ultra Funds 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 (for an UltraShort Fund or an UltraShort Fund) 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. This would be the case with downward single-day or intraday movements in the underlying benchmark of an Ultra Fund or upward single-day or intraday movements in the benchmark of an UltraShort 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 2015 may specify a January 2016 expiration. As that contract nears expiration, it may be replaced by selling the January 2016 contract and purchasing the contract expiring in March 2016. 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 2016 contract would take place at a price that is higher than the price at which the March 2016 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 or a Matching VIX Fund that invests in such futures, and positively affect a Short Fund or an UltraShort 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 and UltraShort Funds, and positively affect the Ultra 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.

137

Gold and silver historically exhibit 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. It is generally believed this is because the market needs to build inventories for most of the year in order to have enough storage to make it through a normal winter. Periods of backwardation are typically thought to be caused by demand shocks or supply shortages such as an unusually cold winter or a hurricane.

Introduction

ProShares Trust II (formerly known as the Commodities and Currencies Trust) (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 March 31, 2016, 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”); and (iii) ProShares UltraShort Bloomberg Commodity, ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Bloomberg Natural Gas, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Australian Dollar, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Commodity, ProShares Ultra Bloomberg Crude Oil, 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.

On February 18, 2016, the Trust announced plans to liquidate ProShares Managed Futures Strategy (ticker symbol: FUTS). ProShares Managed Futures Strategy was closed to purchases and redemptions as of the close of regular trading on the NYSE Arca on March 18, 2016. Beginning March 21, 2016, no secondary market for ProShares Managed Futures Strategy’s Shares remained. Proceeds of the liquidation were distributed to shareholders on March 30, 2016. Any shareholders remaining in the fund on March 30, 2016 automatically had their shares redeemed for cash at ProShares Managed Futures Strategy’s net asset value per Share as of March 21, 2016. On March 31, 2016, the NYSE Arca filed a Form 25 removing the listing of ProShares Managed Futures Strategy on the NYSE Arca. On April 11, 2016, a Form 15 was filed with the U.S. Securities and Exchange Commission (“SEC”) terminating the registration of ProShares Managed Futures Strategy.

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 Commodity, ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Commodity, ProShares Ultra Bloomberg Crude Oil, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen.

ProShare Capital Management LLC serves as the Trust’s Sponsor (the “Sponsor”) and commodity pool operator. Wilmington Trust Company serves as the Trustee of the Trust (the “Trustee”). The Funds are commodity pools, as defined in the Commodity Exchange Act (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.

139

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,” or “Ultra 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.

Each of the Funds generally invests in Financial Instruments (i.e., instruments whose value is derived from the value of an underlying asset, rate or index, 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 its applicable commodity futures index, commodity, currency exchange rate or equity volatility index. 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 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 two times (2x) 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 longer periods. 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 -1x, -2x or 2x of the return of the index 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 are riskier than similarly benchmarked exchange-traded funds that are not geared. 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 Funds should actively manage and monitor their investments, as frequently as daily. The Geared VIX Funds do not seek to achieve their stated objective over a period greater than a single day. Each Matching VIX Fund seeks results (before fees and expenses), both over a single day and over time, 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 Commodity, ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Bloomberg Natural Gas, ProShares Ultra Bloomberg Commodity, ProShares Ultra Bloomberg Crude Oil and ProShares Ultra Bloomberg Natural Gas each have a benchmark that is an index 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.

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

140

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 significant portion of the net assets 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 and each Fund’s trading in futures and 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 months ended March 31, 2016 and 2015 each of the Funds earned interest income as follows:

	Interest Income		Interest Income
	Three Months Ended		Three Months Ended

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.

141

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 the Fund’s benchmark at a specified date and price, should it hold such derivatives 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.

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 recovery 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.

142

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;

• limiting the amount of margin or premium posted at a futures commission merchant (“FCM”); 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 May 2, 2016, 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 amount of payments 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.

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 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 Funds’ final creation/redemption NAV for the three months ended March 31, 2016.

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

143

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. See Note 2 in Item 1 of this Quarterly Report on Form 10-Q for further information.

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. Through July 30, 2014, the Sponsor paid brokerage commissions on VIX futures contracts for the Matching VIX Funds. On July 31, 2014, the Sponsor began paying, and 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.

During the three months ended March 31, 2016, the increase in the Fund’s NAV resulted primarily from an increase 7,996,533 outstanding Shares at December 31, 2015 to 8,046,526 outstanding Shares at March 31, 2016. 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 2x of the daily performance of silver bullion as measured by the London Silver Price. By comparison, during the three months ended March 31, 2015, the increase in the Fund’s NAV resulted primarily from an increase from 7,396,533 outstanding Shares at December 31, 2014 to 7,646,533 outstanding Shares at March 31, 2015. 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 2x of the daily performance of silver bullion as measured by the London Silver Price.

Equity Market Volatility Sensitivity

Each of the VIX Funds is exposed to equity market volatility risk through its holdings of Financial Instruments. The following tables provide information about each of the VIX Funds’ Financial Instruments, which are sensitive to changes in equity market volatility indexes. As of March 31, 2016 and 2015, each of the VIX Funds’ positions were as follows:

ProShares VIX Short-Term Futures ETF

As of March 31, 2016 and 2015, the ProShares VIX Short-Term Futures ETF Fund was exposed to equity market volatility risk through its holding of VIX futures contracts. The following table provides information about the Fund’s positions in VIX futures contracts as of March 31, 2016 and 2015, which were sensitive to equity market volatility risk.

Futures Positions as of March 31, 2016

	Long or				Valuation		Contract		Notional Amount
Contract	Short	Expiration	Contracts		Price		Multiplier		at Value
VIX Futures (CBOE)	Long	April 2016		5,157	$	15.93		1,000	$	82,125,225

VIX Futures (CBOE)	Long	May 2015		4,594		17.83		1,000		81,888,050

The March 31, 2016 and 2015 futures notional values are calculated by multiplying the number of contracts held times the valuation price times the contract multiplier. The notional values will increase (decrease) proportionally with increases (decreases) in the price of the futures contract. 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 match the performance of the Index. While the above information properly represents the then current equity price risk and is adequate for estimating the following day’s gains or losses, estimates of future values over longer periods should take the Fund’s daily rebalancing efforts into account. Future period returns, before fees and expenses, cannot be estimated simply by estimating the return of the Index. See “Item 1A. Risk Factors” in the Trust’s Annual Report on Form 10-K for the year ended December 31, 2015 filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 29, 2016 (the “Form 10-K”), for additional information regarding performance for periods longer than a single day.

The March 31, 2016 and 2015 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 Index for every $1.00 of net assets. While the above information properly represents the then current equity price risk and is adequate for estimating the following day’s gains or losses, estimates of future values over longer periods should take the Fund’s daily rebalancing efforts into account. Future period returns, before fees and expenses, cannot be estimated simply by estimating the return of the Index and multiplying by negative one. See “Item 1A. Risk Factors” in the Form 10-K for additional information regarding performance for periods longer than a single day.

The March 31, 2016 and 2015 futures notional values are calculated by multiplying the number of contracts held times the valuation price times the contract multiplier. 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. While the above information properly represents the then current equity price risk and is adequate for estimating the following day’s gains or losses, estimates of future values over longer periods should take the Fund’s daily rebalancing efforts into account. 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 for additional information regarding performance for periods longer than a single day.

Bloomberg Commodity Index	UBS AG	Short		98.1230		(2,475,856	)

The March 31, 2016 and 2015 short swap notional values are calculated by multiplying units times the closing level of the Index. These short notional values will increase (decrease) proportionally with decreases (increases) in the level of the Index. 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 Index for every $1.00 of net assets. While the above information properly represents the then current commodity price risk and is adequate for estimating the following day’s gains or losses, estimates of future values over longer periods should take the Fund’s daily rebalancing efforts into account. Future period returns, before fees and expenses, cannot be estimated simply by estimating the return of the Index and multiplying by negative two. See “Item 1A. Risk Factors” in the Form 10-K, 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 March 31, 2016 and 2015 short futures notional values are calculated by multiplying the number of contracts held times the valuation price times the contract multiplier. The March 31, 2016 and 2015 short swap notional values are calculated by multiplying the number of units times the closing level of the Index. These short notional values will increase (decrease) proportionally with decreases (increases) 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 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 Index for every $1.00 of net assets. While the above information properly represents the then current commodity price risk and is adequate for estimating the following day’s gains or losses, estimates of future values over longer periods should take the Fund’s daily rebalancing efforts into account. Future period returns, before fees and expenses, cannot be estimated simply by estimating the return of the Index and multiplying by negative two. See “Item 1A. Risk Factors” in the Form 10-K 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.

ProShares UltraShort Bloomberg Natural Gas:

As of March 31, 2016 and 2015, the ProShares UltraShort Bloomberg Natural Gas Fund was exposed to inverse commodity price risk through its holding of Natural Gas futures contracts.

The March 31, 2016 and 2015 futures notional values are calculated by multiplying the number of contracts held times the valuation price times the contract multiplier. The March 31, 2016 and 2015 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. While the above information properly represents the then current commodity price risk and is adequate for estimating the following day’s gains or losses, estimates of future values over longer periods should take the Fund’s daily rebalancing efforts into account. 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 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.

181

the above information properly represents the then current exchange rate price risk and is adequate for estimating the following day’s gains or losses, estimates of future values over longer periods should take the Fund’s daily rebalancing efforts into account. Future period returns, before fees and expenses, cannot be estimated simply by estimating the appreciation or depreciation of the yen and multiplying by two. See “Item 1A. Risk Factors” in the Form 10-K 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 of 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, whether positive or negative, of its corresponding benchmark. Each Short Fund seeks daily investment results (before fees and expenses) that correspond to 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 two times (2x) 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 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 two or negative two. Each Matching VIX Fund seek investment results (before fees and expenses), both over a single day and over time, that match the performance of a benchmark. 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 for additional information regarding performance for periods longer than a single day. The Matching VIX Funds seek to achieve their stated objectives both over a single day and over time.

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 direct 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 as well as the development of drastic market occurrences could ultimately lead to a loss of all or substantially all of investors’ capital.

As described above in Item 2 of 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.

182

Commodity Price Sensitivity

As further described in “Item 1A. Risk Factors” in the Form 10-K, 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, 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).

Equity Market Volatility Sensitivity

As further described in “Item 1A. Risk Factors” in the Form 10-K, 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 (-1x, -2x, or 2x), 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 during the day also affects whether the Fund’s portfolio needs to be re-positioned. For example, if the index for an Ultra 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

183

should fall. As a result, the Fund’s long exposure will generally need to be decreased. Net assets for Short Funds or UltraShort 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 or an UltraShort 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 a non-interest bearing demand deposit account. The Funds 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).

(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 re-allocated 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. On June 26, 2012, a post-effective amendment to the Registration Statement on Form S-3 (File No. 333-163511) was declared effective, which registered additional Shares for ProShares Ultra Bloomberg Crude Oil and terminated the offerings for certain publicly offered Funds and certain Funds that had never been publicly offered. New offerings for those Funds that had been publicly offered were registered on an accompanying Registration Statement on Form S-1 (File No. 333-176878), which was also declared effective on June 26, 2012. On September 24, 2012, a Registration Statement on Form S-1 (File No. 333-183672) was declared effective, which registered additional Shares for ProShares Ultra VIX Short-Term Futures ETF, ProShares VIX Short-Term Futures ETF and ProShares Short VIX Short-Term Futures ETF. This registration statement (File No. 333-183672) was a combined prospectus and acted as a post-effective amendment to the Form S-1 (File No. 333-176878). On September 27, 2012, a Registration Statement on Form S-3 (File No. 333-183674) was declared effective, which registered additional Shares for ProShares Ultra Bloomberg Crude Oil, ProShares UltraShort Bloomberg Crude Oil and ProShares UltraShort Euro. This registration statement was a combined prospectus and acted as a post-effective amendment to the Form S-3 (File No. 333-163511). On September 28, 2012, a post-effective amendment to a Registration Statement on Form S-1 (File No. 333-178707) was declared effective, terminating the proposed offerings of several unlaunched currency funds. On January 30, 2013, a Registration Statement on Form S-1 (File No. 333-185288) was declared effective. That registration statement, which registered additional Shares to ProShares Short VIX Short-Term Futures ETF, acted as a combined prospectus and post-effective amendment to the Trust’s Form S-1 Registration Statements (File Nos. 333-183672 and 333-178707).

Also, on January 30, 2013, a Registration Statement on Form S-3 (File No. 333-185289) was declared effective. That registration statement, which registered additional Shares to ProShares Ultra Bloomberg Crude Oil, ProShares UltraShort Euro, ProShares Ultra VIX Short-Term Futures ETF and ProShares VIX Short-Term Futures ETF, acted as a combined prospectus and post-effective amendment to the Trust’s Form S-1 Registration Statement (File No. 333-193672) and Form S-3 Registration Statement (File No. 333-183674). On April 24, 2013, a post-effective amendment to the Form S-1 Registration Statement (File No. 333-185288) was declared effective, terminating the registered but unlaunched offerings related to: ProShares UltraPro Short Euro, ProShares Managed Futures Strategy and ProShares Commodity Managed Futures Strategy. On April 29, 2013, a Registration Statement on Form S-3 (File No. 333-187820) was declared effective, which registered additional Shares for ProShares Ultra Bloomberg Crude Oil, ProShares UltraShort Bloomberg Crude

186

Oil, ProShares Ultra Silver, ProShares UltraShort Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra VIX Short-Term Futures ETF and ProShares VIX Short-Term Futures ETF. That registration statement was a combined prospectus and acted as a post-effective amendment to the Form S-3 (File No. 333-185289). On May 21, 2013, a Registration Statement on Form S-1 (File 333-188215) was declared effective, which registered additional Shares for ProShares Ultra Bloomberg Natural Gas, ProShares UltraShort Bloomberg Natural Gas, ProShares Short VIX Short-Term Futures ETF and ProShares VIX Mid-Term Futures ETF. That registration statement was a combined prospectus and acted as a post-effective amendment to the Form S-1 (File No. 333-185288). On July 30, 2013, a Registration Statement on Form S-3 (File No. 333-189967) was declared effective, which registered additional Shares for ProShares Bloomberg Crude Oil and ProShares UltraShort Yen and partially terminated registered and unissued Shares of ProShares Ultra Bloomberg Crude Oil, ProShares Ultra Silver, ProShares UltraShort Silver, ProShares UltraShort Euro and ProShares VIX Short-Term Futures ETF. That registration statement was a combined prospectus and acted as a post-effective amendment to the Form S-3 (File No. 333-187820). On May 6, 2014, a post-effective amendment to the Form S-1 Registration Statement (File No. 333-188215) was declared effective, updating the Form S-1 Registration Statement by, among other things, incorporating by reference the audited financial statements for the fiscal year ended December 31, 2013. The post-effective amendment did not register any additional shares. On July 30, 2014, a Registration Statement on Form S-1 (File No. 333-196884) was declared effective, which partially terminated registered and unissued Shares of ProShares VIX Mid-Term Futures ETF, ProShares Ultra Bloomberg Commodity, ProShares Ultra Euro, ProShares Ultra Yen and ProShares UltraShort Bloomberg Commodity. That registration statement was a combined prospectus and acted as a post-effective amendment to two Form S-1 registration statements (File Nos. 333-188215 and 333-185288). On July 30, 2014, a Registration Statement on Form S-3 (File No. 333-196885) was also declared effective, which registered additional Shares for ProShares Ultra Bloomberg Crude Oil, ProShares UltraShort Bloomberg Crude Oil and ProShares UltraShort Euro and partially terminated registered and unissued Shares of ProShares Ultra Gold, ProShares Ultra Silver and ProShares UltraShort Silver. That Registration Statement also was a combined prospectus and acted as a post-effective amendment to the Form S-3 (File No. 333-189967). Through the July 30, 2014 filings, ProShares Short VIX Short-Term Futures ETF was transferred from the Form S-1 to the Form S-3. On September 29, 2014, a Registration Statement on Form S-1 (File No. 333-198189) was declared effective, which registered a new offering of the Managed Futures Fund and acted as a post-effective amendment to the Form S-1 Registration Statement (File No. 333-196884). On November 25, 2014, a Registration Statement on Form S-1 (File No. 333-199642) was declared effective, which registered additional Shares for ProShares Ultra Bloomberg Natural Gas, ProShares UltraShort Bloomberg Natural Gas and ProShares UltraShort Silver. That registration statement was a combined prospectus and acted as a post-effective amendment to the Form S-1 registration statement (File No. 333-198189) and the Form S-3 registration statement (333-196885). On November 25, 2014, a Registration Statement on Form S-3 (File No. 333-199641) was also declared effective, which registered additional Shares for ProShares Ultra Bloomberg Crude Oil, ProShares Ultra Gold, ProShares UltraShort Gold, ProShares Ultra Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra VIX Short-Term Futures ETF, ProShares Short VIX Short-Term Futures ETF and ProShares VIX Short-Term Futures ETF. That Registration Statement also was a combined prospectus and acted as a post-effective amendment to the Form S-3 (File No. 333-196885). Through the November 25, 2014 filings, ProShares UltraShort Silver was transferred from the Form S-3 to the Form S-1. On March 31, 2015, a Registration Statement on Form S-1 (File No. 333-202724) was declared effective, which registered additional Shares for ProShares VIX Mid-Term Futures ETF, ProShares Managed Futures Strategy, ProShares Ultra Bloomberg Commodity, ProShares Ultra Bloomberg Natural Gas, ProShares UltraShort Bloomberg Natural Gas, ProShares UltraShort Silver, ProShares Ultra Australian Dollar, ProShares UltraShort Australian Dollar, ProShares Ultra Euro, ProShares Short Euro and ProShares Ultra Yen. That registration statement was a combined prospectus and acted as a post-effective amendment to the Form S-1 registration statement (File No. 333-199642). On March 31, 2015, a Registration Statement on Form S-3 (File No. 333-202725) was also declared effective, which registered additional Shares for ProShares Ultra Bloomberg Crude Oil, ProShares UltraShort Bloomberg Crude Oil, ProShares Ultra Gold, ProShares UltraShort Gold, ProShares Ultra Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra VIX Short-Term Futures ETF, ProShares Short VIX Short-Term Futures ETF and ProShares VIX Short-Term Futures ETF. That Registration Statement also was a combined prospectus

187

and acted as a post-effective amendment to the Form S-3 (File No. 333-199641). On August 11, 2015, a Registration Statement on Form S-1 (File No. 333-202724) was declared effective which removed ProShares Ultra Australian Dollar from the Form S-1; no additional shares were registered with that filing. That registration statement was a combined prospectus and acted as a pre-effective amendment to post-effective amendment No. 1 of the Form S-1. On March 30, 2016, Post-Effective Amendment No. 1 to the Registration Statement on Form S-3 (File No. 333-202725) was declared effective, which removed from registration all of the Shares that remained unsold thereunder as of the close of business on March 30, 2016. On March 30, 2016, a Registration Statement on Form S-3 (File No. 333-210024) was declared effective, which registered additional Shares for ProShares Ultra Bloomberg Crude Oil, ProShares UltraShort Bloomberg Crude Oil, ProShares Ultra Gold, ProShares UltraShort Gold, ProShares Ultra Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra VIX Short Term Futures ETF, ProShares Short VIX Short-Term Futures ETF, ProShares VIX Short Term Futures ETF. Thus, as of March 31, 2016, the Trust had two effective registration statements outstanding: 1) a Form S-1 Registration Statement (No. 333-202724); and 2) a Form S-3 Registration Statement (No. 333-210024).

Substantially all of the proceeds received by each Fund from the issuance and sale of Shares to Authorized Participants are used by each Fund to enter into Financial Instruments relating to that Fund’s benchmark in combination with cash or cash equivalents and/or U.S. Treasury securities or other high credit quality, short-term fixed-income or similar securities (such as shares of money market funds and collateralized repurchase agreements) that may in part be used for direct investment or deposited with the FCMs as margin in connection with futures contracts or in segregated accounts at the Funds’ custodian bank as collateral for swap agreements or forward contracts, as applicable. Each Geared Fund continuously offers and redeems its Shares in blocks of 50,000 Shares, and each Matching VIX Fund continuously offers and redeems Shares in blocks of 25,000 Shares.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization

NOTE 1 – ORGANIZATION

ProShares Trust II (formerly known as the Commodities and Currencies Trust) (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 March 31, 2016, 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”); and (iii) ProShares UltraShort Bloomberg Commodity, ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Bloomberg Natural Gas, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Australian Dollar, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Commodity, ProShares Ultra Bloomberg Crude Oil, 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.

On May 22, 2015, the Trust announced plans to liquidate ProShares Ultra Australian Dollar (ticker symbol: GDAY). ProShares Ultra Australian Dollar was closed to purchases and redemptions as of the close of regular trading on the NYSE Arca on June 18, 2015. Beginning June 19, 2015, no secondary market for ProShares Ultra Australian Dollar’s Shares remained. Proceeds of the liquidation were distributed to shareholders on June 29, 2015. Any shareholders remaining in the fund on June 29, 2015 automatically had their shares redeemed for cash at ProShares Ultra Australian Dollar’s net asset value per Share as of June 19, 2015. On June 30, 2015, the NYSE Arca filed a Form 25 removing the listing of ProShares Ultra Australian Dollar on the NYSE Arca. On July 10, 2015 a Form 15 was filed with the U.S. Securities and Exchange Commission (“SEC”) terminating the registration of ProShares Ultra Australian Dollar.

On February 18, 2016, the Trust announced plans to liquidate ProShares Managed Futures Strategy (ticker symbol: FUTS). ProShares Managed Futures Strategy was closed to purchases and redemptions as of the close of regular trading on the NYSE Arca on March 18, 2016. Beginning March 21, 2016, no secondary market for ProShares Managed Futures Strategy’s Shares remained. Proceeds of the liquidation were distributed to shareholders on March 30, 2016. Any shareholders remaining in the fund on March 30, 2016 automatically had their shares redeemed for cash at ProShares Managed Futures Strategy’s net asset value per Share as of March 21, 2016. On March 31, 2016, the NYSE Arca filed a Form 25 removing the listing of ProShares Managed Futures Strategy on the NYSE Arca. On April 11, 2016 a Form 15 was filed with the SEC terminating the registration of ProShares Managed Futures Strategy.

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 Commodity, ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Commodity, 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,” or “Ultra 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.

Each “Short” Fund seeks daily investment results (before fees and expenses) that correspond to 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 two times (2x) 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.

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., -1x, -2x or 2x) of the period return of the corresponding benchmark and will likely differ significantly.

The Matching VIX Funds seek to achieve their stated investment objective both over a single day and over time.

Each of the Funds generally invests in Financial Instruments (i.e., instruments whose value is derived from the value of an underlying asset, rate or index, 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 its applicable underlying commodity futures index, commodity, currency exchange rate or equity volatility index. 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, 2015. There were no Share splits or reverse Share splits during the three months ended March 31, 2016. The ticker symbols for these Funds did not change, and each Fund continues to trade on the NYSE Arca.

	Execution Date		Date Trading
	(Prior to Opening		Resumed at Post-
Fund	of Trading)	Type of Split	Split Price
ProShares Ultra VIX Short-Term Futures ETF	May 20, 2015	1-for-5 reverse Share split	May 20, 2015
ProShares UltraShort Silver	November 13, 2015	2-for-1 Share split	November 13, 2015
ProShares Ultra Bloomberg Commodity	May 20, 2015	1-for-4 reverse Share split	May 20, 2015
ProShares Ultra Bloomberg Crude Oil	May 20, 2015	1-for-5 reverse Share split	May 20, 2015
ProShares Ultra Bloomberg Natural Gas	May 20, 2015	1-for-4 reverse Share split	May 20, 2015
ProShares Ultra Yen	May 20, 2015	1-for-4 reverse Share split	May 20, 2015

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.

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

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 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 for the year ended December 31, 2015, as filed with the SEC on February 29, 2016.

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 and disclosures in these financial statements. 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 March 31, 2016, and represents non-segregated cash with the custodian and 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 three months ended March 31, 2016 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 three months ended March 31, 2016.

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 three months ended March 31, 2016.

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 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 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. 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 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. 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. 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.

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 or similar securities 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). Through July 30, 2014, the Sponsor paid brokerage commissions on VIX futures contracts for the Matching VIX Funds. On July 31, 2014, the Sponsor began paying, and 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.

Investments, Debt and Equity Securities [Abstract]

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 and/or used as collateral for a Fund’s trading in futures and 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.

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 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 or an Ultra Fund, the Matching VIX Fund or Ultra 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 or an UltraShort Fund, the Short Fund or UltraShort 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.

The Trust, on behalf of a Fund, may enter into agreements with certain counterparties for derivative transactions. 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 the party under the agreement. This could cause a Fund to have to enter into a new transaction with the same counterparty, enter into 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 March 31, 2016 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. 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, 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 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 March 31, 2016, 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 contract 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. 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 March 31, 2016, 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 March 31, 2016:

Asset (Liability) amounts shown in the table below represent amounts owed to (by) the Funds for the derivative-related investments at March 31, 2016. 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 did not and will not charge the Management Fee in the first year of operation of each Fund in an amount equal to the offering costs. The Sponsor reimbursed 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 services as commodity pool operator, and for managing the business and affairs of the Funds. 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 and 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 Schedule K-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 which 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. Such fees and expenses are those that are non-recurring, unexpected or unusual in nature.

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.

Creation and Redemption of Creation Units

3 Months Ended

Mar. 31, 2016

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 dictated 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 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 $500 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.

Transaction fees for the three months ended March 31, 2016, which are included in the Addition and/or Redemption of Shares on the Statements of Changes in Shareholders’ Equity, were as follows:

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 inverse (-1x), two times the inverse (-2x), or two times (2x) of the return of the Geared Fund’s benchmark for the period. A 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 and UltraShort Funds), as a result of daily rebalancing, the benchmark’s volatility and compounding. Longer holding periods, higher benchmark volatility, inverse exposure and greater leverage each affect the impact of compounding on a 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 for a period as the return of the Fund’s underlying benchmark. The Matching VIX Funds seek to achieve their stated investment objective both over a single day and over time.

Each Ultra and UltraShort 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 Fund with a 2x multiple should be approximately two 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 a Short or UltraShort Fund is designed to return the inverse (-1x) or two times the inverse (-2x) 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 different risks than other 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. Daily objective geared funds, if used properly and in conjunction with the investor’s view on the future direction and volatility of the markets, can be useful tools for investors who want to manage their exposure to various markets and market segments and who are willing to monitor and/or periodically rebalance their portfolios. Shareholders who invest in the Funds should actively manage and monitor their investments, as frequently as daily.

While the Funds expect to meet their investment objectives, several factors may affect their ability to do so. Among these factors are: (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 instruments traded 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, overweighting or underweighting 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 or extreme market volatility 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., -1x, -2x or 2x, 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. In addition, 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

Certain of the Funds will use swap agreements and/or forward contracts as a means to achieve their respective investment objectives. Such Funds will use either swap agreements and/or forward contracts referencing their respective benchmarks. These Funds may also invest in other swap agreements or forward contracts if such instruments tend to exhibit trading prices or returns that correlate with the benchmark or a component of the benchmark and will further the investment objective of the Fund. Certain Funds may invest in swap agreements or forward contracts if position accountability rules or position limits are reached with respect to specific futures contracts or the market for a specific futures contract experiences emergencies (e.g., natural disaster, terrorist attack or an act of God) or disruptions (e.g., a trading halt or a flash crash) that prevent the Funds from obtaining the appropriate amount of investment exposure to the affected futures contract or certain other futures contracts. Although unlikely, those Funds, under these circumstances, could have 100% exposure to swap agreements or forward contracts.

Swap agreements and forward contracts are generally traded in OTC markets and have only recently become subject to regulation by the CFTC. CFTC rules, however, do not cover all types of swap agreements and forward contracts. Investors, therefore, may not receive the protection of CFTC regulation or the statutory scheme of the Commodity Exchange Act (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.

The Funds will be subject to credit risk with respect to the counterparties to the derivatives contracts (whether a clearing corporation in the case of cleared instruments or another third party in the case of OTC uncleared instruments). Unlike in futures contracts, the counterparty to uncleared swap agreements or forward contracts is generally a single bank or other financial institution, rather than a clearing organization backed by a group of financial institutions. As a result, a Fund is subject to credit risk with respect to the amount it expects to receive from counterparties to uncleared swaps and forward contracts 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 its 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 swaps or forward contracts are 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. 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 agreement 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 derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. Transactions entered into directly between two counterparties generally do not benefit from such protections. 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.

Each counterparty and/or any of its affiliates may be an Authorized Participant or shareholder of a Fund.

The counterparty 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 house for performance of financial obligations. However, there can be no assurance that the clearing house, or its members, will satisfy its obligations to the 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.

For example, because the UltraShort Funds and Ultra Funds 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 (for an UltraShort Fund or an UltraShort Fund) 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. This would be the case with downward single-day or intraday movements in the underlying benchmark of an Ultra Fund or upward single-day or intraday movements in the benchmark of an UltraShort 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 2015 may specify a January 2016 expiration. As that contract nears expiration, it may be replaced by selling the January 2016 contract and purchasing the contract expiring in March 2016. 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 2016 contract would take place at a price that is higher than the price at which the March 2016 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 or a Matching VIX Fund that invests in such futures, and positively affect a Short Fund or an UltraShort 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 and UltraShort Funds, and positively affect the Ultra 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 historically exhibit 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. It is generally believed this is because the market needs to build inventories for most of the year in order to have enough storage to make it through a normal winter. Periods of backwardation are typically thought to be caused by demand shocks or supply shortages such as an unusually cold winter or a hurricane.

Use of Estimates and 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 and disclosures in these financial statements. 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.

* 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 three months ended March 31, 2016.

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 three months ended March 31, 2016.

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 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 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. 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 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. 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. 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.

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 or similar securities 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). Through July 30, 2014, the Sponsor paid brokerage commissions on VIX futures contracts for the Matching VIX Funds. On July 31, 2014, the Sponsor began paying, and 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.

Asset (Liability) amounts shown in the table below represent amounts owed to (by) the Funds for the derivative-related investments at March 31, 2016. 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”.
