NOTES TO FINANCIAL STATEMENTS

September 30, 2012

(unaudited)

NOTE 1—ORGANIZATION

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 currently organized into separate series (each, a “Fund” and collectively, the “Funds”). As of September 30, 2012, the following twenty-one series of the Trust have commenced investment operations: (i) ProShares Ultra DJ-UBS Commodity, ProShares UltraShort DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra DJ-UBS Natural Gas, ProShares UltraShort DJ-UBS Natural Gas, ProShares Ultra Gold, ProShares UltraShort Gold, ProShares Ultra Silver, ProShares UltraShort Silver, ProShares Ultra Australian Dollar, ProShares UltraShort Australian Dollar, ProShares Ultra Euro, ProShares UltraShort Euro, ProShares Ultra Yen and ProShares UltraShort Yen (each, a “Leveraged Fund” and collectively, the “Leveraged Funds”); (ii) ProShares Short Euro (the “Short Euro Fund”); (iii) ProShares Ultra VIX Short-Term Futures ETF and ProShares Short VIX Short-Term Futures ETF (each, a “Geared VIX Fund” and collectively, the “Geared VIX Funds”); and (iv) ProShares VIX Short-Term Futures ETF and ProShares VIX Mid-Term Futures ETF (each, a “Matching VIX Fund” and collectively, the “Matching VIX Funds”). 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 Leveraged Fund, Short Euro Fund, Geared VIX Fund or Matching VIX Fund. The Shares of each Leveraged Fund, the Short Euro Fund, each Geared VIX Fund and each Matching VIX Fund are listed on the New York Stock Exchange Archipelago (“NYSE Arca”).

The Trust has also registered shares for thirty-two additional series: (i) ProShares Short DJ-UBS Natural Gas and ProShares Short Gold (each, a “Short Fund” and collectively, the “Short Funds”); (ii) ProShares UltraShort VIX Short-Term Futures ETF, ProShares Ultra VIX Mid-Term Futures ETF, ProShares Short VIX Mid-Term Futures ETF and ProShares UltraShort VIX Mid-Term Futures ETF (each, a “New Geared VIX Fund” and collectively, the “New Geared VIX Funds”); (iii) ProShares Managed Futures Strategy, ProShares Commodity Managed Futures Strategy and ProShares Financial Managed Futures Strategy (each, a “Managed Futures Fund” and collectively, the “Managed Futures Funds”); (iv) ProShares UltraPro Australian Dollar, ProShares Short Australian Dollar, ProShares UltraPro Short Australian Dollar, ProShares UltraPro Canadian Dollar, ProShares Ultra Canadian Dollar, ProShares Short Canadian Dollar, ProShares UltraShort Canadian Dollar, ProShares UltraPro Short Canadian Dollar, ProShares UltraPro Euro, ProShares UltraPro Short Euro, ProShares UltraPro Swiss Franc, ProShares Ultra Swiss Franc, ProShares Short Swiss Franc, ProShares UltraShort Swiss Franc, ProShares UltraPro Short Swiss Franc, ProShares UltraPro Yen, ProShares Short Yen and ProShares UltraPro Short Yen (each, a “New Currency Fund” and collectively, the “New Currency Funds”); and (v) ProShares UltraPro U.S. Dollar, ProShares Ultra U.S. Dollar, ProShares Short U.S. Dollar, ProShares UltraShort U.S. Dollar and ProShares UltraPro Short U.S. Dollar (each, a “Currency Index Fund” and collectively, the “Currency Index Funds”). The Geared VIX Funds and the Matching VIX Funds are collectively referred to as the “VIX Funds” in these Notes to Financial Statements. 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.

On June 25, 2012, the registered offerings for ProShares UltraPro Australian Dollar, ProShares Short Australian Dollar, ProShares UltraPro Short Australian Dollar, ProShares UltraPro Canadian Dollar, ProShares Short Canadian Dollar, ProShares UltraPro Short Canadian Dollar, ProShares UltraPro Euro, ProShares UltraPro Short Euro, ProShares UltraPro Swiss Franc, ProShares Short Swiss Franc, ProShares UltraPro Short Swiss Franc, ProShares UltraPro Yen, ProShares UltraPro Short Yen and the Currency Index Funds, each of which had never been publicly offered, were terminated. On June 26, 2012, the registered offerings for the Short Funds and the New Geared VIX Funds, each of which had never been publicly offered, were terminated. On September 28, 2012, the registered offerings for ProShares Ultra Canadian Dollar, ProShares UltraShort Canadian Dollar, ProShares Ultra Swiss Franc, ProShares UltraShort Swiss Franc and ProShares Short Yen, each of which had never been publicly offered, were terminated. Thus, as of September 30, 2012, the only Funds that have remaining registered amounts are the Managed Futures Funds.

-114-

As of September 30, 2012, each of the Managed Futures Funds had seed capital, but none of the Managed Futures Funds had commenced investment operations; therefore, these Financial Statements do not include Schedules of Investments, Statements of Operations, Statements of Changes in Shareholders’ Equity or Statements of Cash Flows for the Managed Futures Funds.

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 Ultra DJ-UBS Commodity, ProShares UltraShort DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra Gold, ProShares UltraShort Gold, ProShares Ultra Silver, ProShares UltraShort Silver, ProShares Ultra Euro, ProShares UltraShort Euro, ProShares Ultra Yen and ProShares UltraShort Yen.

Eight of the Funds, ProShares Ultra DJ-UBS Commodity, ProShares UltraShort DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra Euro, ProShares UltraShort Euro, ProShares Ultra Yen and ProShares UltraShort Yen, commenced trading on the NYSE Arca on November 25, 2008. Four of the Funds, ProShares Ultra Gold, ProShares UltraShort Gold, ProShares Ultra Silver, and ProShares UltraShort Silver, commenced trading on the NYSE Arca on December 3, 2008. Two of the Funds, ProShares VIX Short-Term Futures ETF and ProShares VIX Mid-Term Futures ETF, commenced trading on the NYSE Arca on January 3, 2011. Two of the Funds, ProShares Ultra VIX Short-Term Futures ETF and ProShares Short VIX Short-Term Futures ETF, commenced trading on the NYSE Arca on October 3, 2011. Two of the Funds, ProShares Ultra DJ-UBS Natural Gas and ProShares UltraShort DJ-UBS Natural Gas, commenced trading on the NYSE Arca on October 4, 2011. One of the Funds, ProShares Short Euro, commenced trading on the NYSE Arca on June 26, 2012. Two of the Funds, ProShares Ultra Australian Dollar and ProShares UltraShort Australian Dollar, commenced trading on the NYSE Arca on July 17, 2012. As of September 30, 2012, the Managed Futures Funds had not yet commenced trading.

Groups of Funds are collectively referred to in several different ways. References to “Ultra Funds,” “Short Funds” or “UltraShort 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. References to “Managed Futures Funds” refer to the different Funds according to which index the Fund intends to gain exposure.

Each “Ultra” Fund seeks daily investment results (before fees and expenses) that correspond to twice (2x) the daily performance 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 twice the inverse (-2x) of the daily performance of its corresponding benchmark. Daily performance is measured from the calculation of one NAV to the next.

Each of the Geared Funds generally invests in Financial Instruments (i.e., commodity-based, currency-based or equity market volatility-based instruments whose value is derived from the value of an underlying asset, rate or index, including futures contracts and options on futures contracts, swap agreements, forward contracts and other commodity-based or currency-based options contracts) as a substitute for investing directly in commodities, currencies, or equity market volatility products in order to gain exposure to the commodity index, currency benchmark, commodity, currency or to an equity market volatility index. Financial Instruments also are used to produce economically “leveraged” or “inverse” investment results for the Funds. Each Matching VIX Fund seeks daily investment results (before fees and expenses) that match the performance of a benchmark. Each Geared VIX Fund seeks daily investment results (before fees and expenses) that correspond to a multiple, the inverse or inverse multiple of the daily performance of a benchmark. 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”). The Managed Futures Funds will seek to provide investment results (before fees and expenses) that

-115-

correspond to the performance of the S&P Dynamic Futures Index (the “DFI” or the “Index”), the S&P Dynamic Commodities Futures Index (the “DCFI”) or the S&P Dynamic Financial Futures Index (the “DFFI”) (each a “Sub-Index” and collectively, the “Sub-Indexes”). Each Managed Futures Fund intends to obtain exposure to the Index or to a Sub-Index, as applicable, by investing primarily in unleveraged positions in U.S. exchange-traded futures contracts on sixteen different tangible commodities (the “Commodity Futures Contracts”) or futures contracts on eight different financials, such as major currencies and U.S. Treasury securities (the “Financial Futures Contracts” and together with the Commodity Futures Contracts, the “Index Components”).

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 one day should not be expected to be a simple multiple (e.g., 2x, -1 or -2x) of the period return of the corresponding benchmark and will likely differ significantly. The Matching VIX Funds and the Managed Futures Funds seek to achieve their stated investment objective both over a single day and over time.

ProShares Ultra DJ-UBS Commodity, ProShares UltraShort DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra DJ-UBS Natural Gas and ProShares UltraShort DJ-UBS 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.

Renaming of Index

Effective as of January 2, 2012, the official name for the Dow Jones-UBS Crude Oil Sub-Index^SM (Ticker: DJUBSCL) changed to the Dow Jones-UBS WTI Crude Oil Sub-Index^SM. The ticker did not change as a result of the name change.

Share Splits and Reverse Share Splits

Prior to the opening of trading on the NYSE Arca on February 25, 2011, ProShares UltraShort DJ-UBS Commodity and ProShares UltraShort DJ-UBS Crude Oil executed a 1-for-5 reverse split of Shares and ProShares UltraShort Silver and ProShares Ultra DJ-UBS Crude Oil executed a 1-for-4 reverse split of Shares. The funds traded at their post-split prices on February 25, 2011. The ticker symbols for the funds did not change, and they continue to trade on the NYSE Arca.

Prior to the opening of trading on the NYSE Arca on October 13, 2011, ProShares Ultra Silver executed a 2-for-1 split of Shares and ProShares UltraShort Yen executed a 1-for-3 reverse split of Shares. The funds traded at their post-split prices on October 13, 2011. The ticker symbols for the funds did not change, and they continue to trade on the NYSE Arca.

Prior to the opening of trading on the NYSE Arca on March 8, 2012, ProShares Ultra VIX Short-Term Futures ETF executed a 1-for-6 reverse split of Shares. The fund traded at its post-split price on March 8, 2012. The ticker symbol for the fund did not change, and it continues to trade on the NYSE Arca.

Prior to the opening of trading on the NYSE Arca on May 11, 2012, ProShares UltraShort DJ-UBS Natural Gas executed a 3-for-1 split of Shares and ProShares Ultra DJ-UBS Natural Gas and ProShares UltraShort Silver executed a 1-for-5 reverse split of Shares. The funds traded at their post-split prices on May 11, 2012. The ticker symbols for the funds did not change, and they continue to trade on the NYSE Arca.

Prior to the opening of trading on the NYSE Arca on September 7, 2012, ProShares Ultra VIX Short-Term Futures ETF executed a 1-for-10 reverse split of Shares. The fund traded at its post-split price on September 7, 2012. The ticker symbol for the fund did not change, and it continues to trade on the NYSE Arca.

The reverse splits were applied retroactively for all periods presented, reducing the number of Shares outstanding for each of ProShares UltraShort DJ-UBS Commodity, ProShares UltraShort DJ-UBS Crude Oil, ProShares UltraShort Silver, ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort Yen, ProShares Ultra VIX Short-Term Futures ETF and ProShares Ultra DJ-UBS Natural Gas, 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 split.

-116-

The splits were applied retroactively for all periods presented, increasing the number of Shares outstanding for ProShares Ultra Silver and ProShares UltraShort DJ-UBS Natural Gas, 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.

NOTE 2—SIGNIFICANT ACCOUNTING POLICIES

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 U.S. Securities and Exchange Commission (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, 2011, as filed with the SEC on February 29, 2012.

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 September 30, 2012, and represents non-segregated cash with the custodian and does not include short-term investments.

Final Net Asset Value for Fiscal Period

The times of the calculation of the Leveraged Funds’, the Short Euro Fund’s, the Geared VIX Funds’ and the Matching VIX Funds’ final net asset value for creation and redemption of fund Shares for the three months ended September 30, 2012 were as follows. All times are Eastern Standard Time:

-117-

	NAV Calculation Time		NAV Calculation Date
Ultra Silver, UltraShort Silver		7:00 A.M.		September 30
Ultra Gold, UltraShort Gold		10:00 A.M.		September 30
Ultra DJ-UBS Commodity, UltraShort DJ-UBS Commodity		2:30 P.M.		September 30
Ultra DJ-UBS Crude Oil, UltraShort DJ-UBS Crude Oil		2:30 P.M.		September 30
Ultra DJ-UBS Natural Gas, UltraShort DJ-UBS Natural Gas		2:30 P.M.		September 30
Ultra Australian Dollar, UltraShort Australian Dollar		4:00 P.M.		September 30
Ultra Euro, Short Euro, UltraShort Euro		4:00 P.M.		September 30
Ultra Yen, UltraShort Yen		4:00 P.M.		September 30
Ultra VIX Short-Term Futures ETF, VIX Short-Term Futures ETF, Short VIX Short-Term Futures ETF, VIX Mid-Term Futures ETF		4:15 P.M.		September 30

Although the Leveraged Funds’, the Short Euro Fund, the Geared VIX Funds’ and the Matching VIX 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 September 30, 2012.

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 Leveraged Funds, the Short Euro Fund, the Geared VIX Funds and the Matching VIX 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 Leveraged Funds’, Short Euro Fund’s, Geared VIX Funds’ and Matching VIX Funds’ final creation/redemption NAV for the three months ended September 30, 2012.

Investment Valuation

Short-term investments are valued at market price. Treasury securities having a maturity of greater than sixty days are valued at market price. In each of these situations, valuations are typically categorized as Level I in the fair value hierarchy.

Derivatives (futures contracts, swap agreements, forward agreements and foreign currency forward contracts) are generally valued using independent sources and/or agreements with counterparties or other procedures as determined by the Sponsor. Futures contracts, except for those entered into by the Gold, Silver, Australian Dollar and Short Euro Funds, are generally valued at the last settled price on the applicable exchange on which that future trades. Futures contracts entered into by the Gold, Silver, Australian Dollar and Short Euro Funds are valued at the last sales price prior to the time at which the NAV per Share of a Fund is determined. For financial reporting purposes, all futures contracts are valued at last settled price. 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 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. 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 Leveraged Funds’, the Short Euro Fund’s, the Geared VIX Funds’ and the Matching VIX Funds’ policies are intended to result in a calculation of a Leveraged Fund’s, the Short Euro Fund’s, a Geared VIX Fund’s or a Matching VIX Fund’s NAV that fairly reflects investment values as of the time of pricing, a Leveraged Fund, the Short Euro Fund, a Geared VIX Fund or a Matching VIX 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 a Leveraged Fund, the Short Euro Fund, a Geared VIX Fund or a Matching 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.

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 September 30, 2012 using the fair value hierarchy:

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 or will pay 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 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. For the nine months ended September 30, 2012, the Sponsor paid and is currently paying brokerage commissions on VIX futures contracts for the Matching VIX Funds.

Federal Income Tax

Each Fund is registered as a series of a Delaware statutory trust and is or will be 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 or will be 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 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 that the Sponsor believes in combination should produce returns consistent with a Fund’s objective.

All open derivative positions at period-end for each Fund are disclosed in the Schedule of Investments and the notional value of these open positions relative to the shareholders’ equity of each Fund is generally representative of the notional value of open positions to shareholders’ equity throughout the reporting period for each respective Fund. The volume associated with derivative positions varies on a daily basis as each Fund transacts derivative contracts in order to achieve the appropriate exposure, as expressed in notional value, in comparison to shareholders’ equity consistent with each Fund’s investment objective.

-121-

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 effected. The initial margin is segregated as cash 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. 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.

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) commodities/indices, or to create an economic hedge against a position. Swap agreements are two-party contracts entered into primarily with major global financial institutions for a specified period, ranging from a day to more than one year. 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. In the case of futures contracts based indices, such as those used by the Commodity Index Funds, the reference interest rate is zero. 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 an Ultra Fund, the Ultra Fund would be entitled to settlement payments in the event the benchmark increases and would be required to make payments to the swap counterparties in the event 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 an UltraShort Fund, the UltraShort Fund would be required to make payments to the swap counterparties in the event the benchmark increases and would be entitled to settlement payments in the event the benchmark decreases, adjusted for any transaction costs or trading spreads on the notional amount the Funds may pay.

-122-

The net amount of the excess, if any, of each Fund’s obligations over its entitlements with respect to each swap agreement is accrued on a daily basis and an amount of cash and/or securities having an aggregate NAV at least equal to such accrued excess is maintained in a segregated account by the Funds’ 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 Index.

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 (commodity price 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 an imperfect correlation 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 counterparty. A Fund will 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 September 30, 2012 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. 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 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 September 30, 2012, the collateral posted by counterparties consisted of cash and U.S. Treasury Securities.

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 the over-the-counter (“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.

-123-

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 are, in general, not cleared or guaranteed by a third party. The Funds may collateralize 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 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 September 30, 2012, the collateral posted by counterparties consisted of cash and 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 that their counterparties post margin.

A Fund will 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.

NOTE 4—AGREEMENTS

Management Fee

Each Leveraged Fund, the Short Euro Fund and each Geared VIX Fund pays or will pay 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. In the first year of the Leveraged Funds’, the Short Euro Fund’s and the VIX Funds’ operations, the Sponsor did not charge its fee in an amount equal to the organization and offering costs. The Sponsor reimbursed or will reimburse each Leveraged Fund, the Short Euro Fund and each Geared VIX Fund, if applicable, to the extent that its offering costs exceeded or exceed 0.95% of its average daily NAV of each Fund for the first year of operations. 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. The Sponsor will not charge its fee in the first year of operation of each Fund in an amount equal to the offering costs. The Sponsor has agreed to reimburse each Fund to the extent that its offering costs exceed the Management Fee for the first year of operations. The Management Fee is or will be paid in consideration of the Sponsor’s services as commodity pool operator and commodity trading advisor, and for managing the business and affairs of the Funds. From the Management Fee, the Sponsor pays or will pay the fees and expenses of the Administrator, Custodian, Distributor, ProFunds Distributors, Inc. (“PDI”), an affiliated broker-dealer of the Sponsor, Transfer Agent and any index licensors for the Funds, the routine operational, administrative and other ordinary expenses of each Fund, 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, Financial Industry Regulatory Authority (“FINRA”) filing fees, individual 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. For the nine months ended September 30, 2012, the Sponsor paid and is currently paying brokerage commissions on VIX futures contracts for the Matching VIX Funds. Each Fund incurs and pays, and each Managed Futures Fund will incur and pay, its non-recurring and unusual fees and expenses.

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, 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 or will be 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 or will be 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.

-131-

Routine Operational, Administrative and Other Ordinary Expenses

The Sponsor pays or will pay all of the routine operational, administrative and other ordinary expenses of each Fund generally, as determined by the Sponsor including, but not limited to, fees and expenses of the Administrator, Custodian, Distributor, PDI, Transfer Agent, fees payable to index providers, accounting and auditing fees and expenses, 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, FINRA filing fees, individual Schedule K-1 preparation and mailing fees not exceeding 0.10% per annum of the NAV of a Fund, and report preparation and mailing expenses.

Non—Recurring Fees and Expenses

Each Fund pays or will pay all 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 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.

NOTE 5—ORGANIZATION AND OFFERING COSTS

Organization costs are expensed as incurred and offering costs will be amortized by the Funds over a twelve month period on a straight-line basis.

The Sponsor did not and will not charge its Management Fee in the first year of operations of each Leveraged Fund, the Short Euro Fund, each Geared VIX Fund or each Matching VIX Fund in an amount equal to the organization and offering costs. The Sponsor reimbursed or will reimburse each Fund to the extent that its organization and offering costs exceeded 0.95% of each Leveraged Fund’s, the Short Euro Fund’s or each Geared VIX Fund’s and 0.85% of each Matching VIX Fund’s average daily NAV for the first year of operations.

The Sponsor will not charge its Management Fee in the first year of operations of each Fund in an amount equal to the offering costs. The Sponsor has agreed to reimburse each Managed Futures Fund to the extent that its offering costs exceed 0.95% of its average daily NAV for the first year of operations. At September 30, 2012, amounts payable for offering costs are reflected in the Statement of Financial Condition for each Managed Futures Fund.

NOTE 6—CREATION AND REDEMPTION OF CREATION UNITS

Each Fund issues and redeems or will issue and redeem Shares from time to time, but only in one or more Creation Units. A Creation Unit is or will be a block of 50,000 Shares of a Geared Fund or a Managed Futures 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.

-132-

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. Authorized Participants also may pay a variable transaction fee to the Fund of up to 0.10% 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 and nine months ended September 30, 2012, which are included in the Sale 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 one day (as measured from NAV calculation time to NAV calculation time), and not for any other period. The return of a Geared Fund for a period longer than a day is the result of its return for each day compounded over the period and usually will differ from the multiple (2x), the inverse (-1x) or the inverse multiple (-2x) of the return of the Geared Fund’s benchmark for the period. A Fund will lose money if its index performance is flat over time, and it is possible for a Geared Fund to lose money over time even if the performance of its index increases (or decreases in the case of UltraShort or Short Funds), as a result of daily rebalancing, the benchmark’s volatility and compounding. Longer holding periods, higher index volatility 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 index. The Matching VIX Funds and Managed Futures Funds seek to achieve their stated investment objective both over a single day and over time.

Each Ultra or 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 twice as volatile on a daily basis as is the return of a fund with an objective of matching the same benchmark. The daily return of an UltraShort Fund with a -2x multiple is designed to return twice 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 instruments held by a Fund, such as swaps, futures contracts and/or forward contracts, and the performance of the applicable underlying indices, commodities or currencies; (3) bid-ask spreads on such instruments; (4) fees, expenses, transaction costs, financing costs associated with the use of derivatives 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; and (10) accounting standards.

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 over- or under-exposed to the benchmark may prevent such 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 (e.g., 2x or -2x) 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.

-146-

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 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.

Swap agreements and forward contracts are generally traded over the counter and are essentially unregulated by the CFTC. Investors, therefore, do not receive the protection of CFTC regulation or the statutory scheme of the CEA in connection with each Fund’s swap agreements or forward contracts. The lack of regulation in these markets could expose investors to significant losses under certain circumstances including in the event of trading abuses or financial failure by participants.

Unlike in futures contracts, the counterparty to 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 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. 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.

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.

Although the counterparty to a futures contract is often a clearing organization backed by a group of financial institutions, there may also be instances in which the counterparty could fail to perform its obligations, causing significant losses to a Fund.

Leverage Risk

The 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.

-147-

For example, because the Ultra and UltraShort Funds include a two times (2x) or two times the inverse (-2x) multiplier, a single-day movement in the relevant benchmark approaching 50% at any point in the day could result in the total loss or almost total loss of an investor’s investment if that movement is contrary to the investment objective of the Fund in which an investor has invested, even if such Fund’s benchmark subsequently moves in an opposite direction, eliminating all or a portion of the movement. This would be the case with downward single-day or intraday movements in the underlying benchmark of an Ultra Fund or upward one-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 August 2012 may specify an October 2012 expiration. For an Ultra Fund and a Matching VIX Fund, as that contract nears expiration, it may be replaced by selling the October 2012 contract and purchasing the contract expiring in December 2012. 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 October 2012 contract would take place at a price that is higher than the price at which the December 2012 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 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.

NOTE 9—LEGAL PROCEEDINGS

The Trust and certain principals of the Sponsor have been named as defendants (along with several other parties) in a consolidated class action lawsuit filed in the United States District Court for the Southern District of New York, styled In re ProShares Trust Securities Litigation, Civ. No. 09-cv-6935. The complaint, as amended, alleged that the defendants violated Sections 11 and 15 of the Securities Act of 1933 by including untrue statements of material fact and omitting material facts in the Registration Statement for one or more ProShares ETFs and allegedly failing to adequately disclose the Funds’ investment objectives and risks. The six Funds of the Trust named in the complaint were ProShares Ultra Silver, ProShares UltraShort Gold, ProShares Ultra Gold, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra DJ-UBS Crude Oil and ProShares UltraShort Silver. On September 10, 2012, the District Court issued an Opinion and Order dismissing the class action lawsuit in its entirety. On October 3, 2012, the plaintiffs filed a Notice of Appeal appealing the dismissal. The Trust believes the complaint is without merit and that the anticipated outcome will not adversely impact the operation of the Trust or any of its Funds. Accordingly, no loss contingency has been recorded in the balance sheet and the amount of loss, if any, cannot be reasonably estimated at this time.

NOTE 10—SUBSEQUENT EVENTS

Management has evaluated the possibility of subsequent events existing in the Trust’s and the Funds’ financial statements through the date the financial statements were issued. The subsequent events were as follows:

On September 20, 2012, the Trust announced a 2-for-1 split of the Shares of beneficial interest of ProShares Short VIX Short-Term Futures (NYSE Arca symbol “SVXY”). Prior to the opening of trading on the NYSE Arca on October 5, 2012, ProShares Short VIX Short-Term Futures executed a 2-for-1 split of Shares.

The split was effective for shareholders of record after the close of the markets on October 2, 2012, and payable after the close of the markets on October 4, 2012. The fund traded at its post-split price on October 5, 2012. The ticker symbol for the Fund did not change, and it continues to trade on the NYSE Arca.

The split was applied retroactively for all periods presented, increasing the number of Shares outstanding for ProShares Short VIX Short-Term Futures, and resulted in a proportionate decrease in the price per Share and per Share information of ProShares Short VIX Short-Term Futures. Therefore, the split did not change the aggregate net asset value of a shareholder’s investment at the time of the split.

On September 20, 2012, the Trust announced a 1-for-4 reverse split of the Shares of beneficial interest of ProShares UltraShort Gold (NYSE Arca symbol “GLL”). Prior to the opening of trading on the NYSE Arca on October 5, 2012, ProShares UltraShort Gold executed a 1-for-4 reverse split of Shares.

The reverse split was effective for shareholders of record after the close of the markets on October 4, 2012. The fund traded at its post-split price on October 5, 2012. The ticker symbol for the Fund did not change, and it continues to trade on the NYSE Arca.

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

As of September 30, 2012, the Managed Futures Funds had not yet commenced trading.

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

Groups of Funds are collectively referred to in this Quarterly Report on Form 10-Q in several different ways. References to “Ultra Funds,” “Short Funds” or “UltraShort 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. References to “Managed Futures Funds” refer to the different Funds according to which index the Fund intends to gain exposure.

Each “Ultra” Fund seeks daily investment results (before fees and expenses) that correspond to twice (2x) the daily performance of its corresponding

-151-

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 twice the inverse (-2x) of the daily performance of its corresponding benchmark. Daily performance is measured from the calculation of one NAV to the next.

Each of the Geared Funds generally invests in Financial Instruments (i.e., commodity-based, currency-based or equity market volatility-based instruments whose value is derived from the value of an underlying asset, rate or index, including futures contracts and options on futures contracts, swap agreements, forward contracts and other commodity-based or currency-based options contracts) as a substitute for investing directly in commodities, currencies or equity market volatility products in order to gain exposure to the commodity index, currency benchmark, commodity, currency or to an equity market volatility index. Financial Instruments also are used to produce economically “leveraged” or “inverse” investment results for the Funds. Each Matching VIX Fund seeks daily investment results (before fees and expenses) that match the performance of a benchmark. Each Geared VIX Fund seeks daily investment results (before fees and expenses) that correspond to a multiple, the inverse or inverse multiple of the daily performance of a benchmark. Each VIX Fund intends to obtain exposure to its benchmark by investing in futures contracts (“VIX futures contracts”) based on the Chicago Board Options Exchange (“CBOE”) Volatility Index (the “VIX”). The Managed Futures Funds will seek to provide investment results (before fees and expenses) that correspond to the performance of the S&P Dynamic Futures Index (“DFI”), the S&P Dynamic Commodities Futures Index (“DCFI”) or the S&P Dynamic Financial Futures Index (“DFFI”) (each a “Sub-Index” and collectively, the “Sub-Indexes”). Each Managed Futures Fund intends to obtain exposure to the Index or to a Sub-Index, as applicable, by investing primarily in unleveraged positions in U.S. exchange-traded futures contracts on sixteen different tangible commodities (the “Commodity Futures Contracts”) or futures contracts on eight different financials, such as major currencies and U.S. Treasury securities (the “Financial Futures Contracts” and together with the Commodity Futures Contracts, the “Index Components”).

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 2x, -1x 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 inverse investment results. Shareholders should actively monitor their investments. The Geared VIX Funds do not seek to achieve their stated objective over a period greater than one day. The Matching VIX Funds and the Managed Futures Funds seek to achieve their stated investment objective both over a single day and over time.

ProShares Ultra DJ-UBS Commodity, ProShares UltraShort DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra DJ-UBS Natural Gas and ProShares UltraShort DJ-UBS Natural Gas each have a benchmark that is an index designed to track the performance of commodity futures contracts. 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 and Managed Futures Fund continuously offers and redeems or will offer and redeem its Shares in blocks of 50,000 Shares and each Matching VIX Fund continuously offers and redeems its Shares in blocks of 25,000 Shares (each such block a “Creation Unit”). Only Authorized Participants may purchase and redeem Shares from a Fund and then only in Creation Units. An Authorized Participant is an entity that has entered into an Authorized Participant Agreement with one or more of the Funds. Shares of the Funds are offered to Authorized Participants in Creation Units at each Fund’s respective NAV. Authorized Participants may then offer to the public, from time to time, Shares from any Creation Unit they create at a per-Share market price that varies depending on, among other factors, the trading price of the Shares of each Fund on the NYSE Arca, the NAV and the supply of and demand for the Shares at the time of the offer. Shares from the same Creation Unit may be offered at different times and may have different offering prices based upon the above factors. The form of Authorized Participant Agreement and related Authorized Participant Handbook set forth the terms and conditions under which an

-152-

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 and nine months ended September 30, 2012 and 2011, each of the Funds earned interest income as follows:

Each Fund’s underlying swaps, futures and 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.

-153-

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).

Fund Performance

The following table provides summary performance information for the Fund for the three months ended September 30, 2012 and 2011:

	Three Months  Ended September 30, 2012			Three Months Ended September 30, 2011
NAV beginning of period	$	8,231,730		$	16,695,263

Percentage change in Shares outstanding		(14.3	)%		(10.0	)%
Shares created		—			—
Shares redeemed		50,000			50,000
Per Share NAV beginning of period	$	23.52		$	33.39
Per Share NAV end of period	$	28.00		$	26.02
Percentage change in per Share NAV		19.1	%		(22.1	)%
Percentage change in benchmark		9.7	%		(11.3	)%
Benchmark annualized volatility		15.7	%		20.2	%

During the three months ended September 30, 2012, the increase in the Fund’s NAV resulted from the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to 2x of the daily performance of the Dow Jones-UBS Commodity Index. The increase in the Fund’s NAV was offset by a decrease from 350,014 outstanding Shares at June 30, 2012 to 300,014 outstanding Shares at September 30, 2012. By comparison, during the three months ended September 30, 2011, the decrease in the Fund’s NAV resulted primarily from the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to 2x of the daily performance of the Dow Jones-UBS Commodity Index. The decrease in the Fund’s NAV also resulted in part from a decrease from 500,014 outstanding Shares at June 30, 2011 to 450,014 outstanding Shares at September 30, 2011.

For the three months ended September 30, 2012 and 2011, the Fund’s daily performance had a statistical correlation over 0.99 to 2x of the daily performance of its benchmark. The Fund’s per Share NAV increase of 19.1% for the period ended September 30, 2012, as compared to the decrease of 22.1% for the period ended September 30, 2011, was primarily due to an appreciation in the value of the assets of the Fund during the three months ended September 30, 2012.

During the three months ended September 30, 2012, the Fund’s per Share NAV reached its high for the period on September 14, 2012 at $29.39 per Share and reached its low for the period on July 2, 2012 at $23.60 per Share. By comparison, during the three months ended September 30, 2011, the Fund’s per Share NAV reached its high for the period on July 26, 2011 at $36.90 per Share and reached its low for the period on September 30, 2011 at $26.02 per Share.

The benchmark’s rise of 9.7% for the three months ended September 30, 2012, as compared to the benchmark’s decline of 11.3% for the three months ended September 30, 2011, can be attributed to appreciation of the underlying components of the index during the three months ended September 30, 2012.

During the three months ended September 30, 2012, the decrease in the Fund’s NAV resulted primarily from a decrease from 17,649,170 outstanding Shares at June 30, 2012 to 12,199,170 outstanding Shares at September 30, 2012. The decrease in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to 2x of the daily performance of the Dow Jones-UBS WTI Crude Oil Sub-Index. By comparison, during the three months ended September 30, 2011, the decrease in the Fund’s NAV resulted primarily from the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to 2x of the daily performance of the Dow Jones-UBS WTI Crude Oil Sub-Index. The decrease in the Fund’s NAV was offset by an increase from 9,999,170 outstanding Shares at June 30, 2011 to 13,949,170 outstanding Shares at September 30, 2011.

For the three months ended September 30, 2012 and 2011, the Fund’s daily performance had a statistical correlation over 0.99 to 2x of the daily performance of its benchmark. The Fund’s per Share NAV increase of 13.0% for the three months ended September 30, 2012, as compared to the decrease of 36.0% for the three months ended September 30, 2011, was primarily due to appreciation in the value of the assets of the Fund during the three months ended September 30, 2012.

During the three months ended September 30, 2012, the Fund’s per Share NAV reached its high for the period on September 14, 2012 at $36.47 per Share and reached its low for the period on July 10, 2012 at $26.90 per Share.

During the three months ended September 30, 2012, the increase in the Fund’s NAV resulted primarily from an increase from 1,669,944 outstanding Shares at June 30, 2012 to 2,869,944 outstanding Shares at September 30, 2012. The increase in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to 2x of the inverse of the daily performance of the Dow Jones-UBS WTI Crude Oil Sub-Index. By comparison, during the three months ended September 30, 2011, the decrease in the Fund’s NAV resulted from a decrease from 3,319,944 outstanding Shares at June 30, 2011 to 1,119,944 outstanding Shares at September 30, 2011. The decrease in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to 2x of the inverse of the daily performance of the Dow Jones-UBS WTI Crude Oil Sub-Index.

For the three months ended September 30, 2012 and 2011, the Fund’s daily performance had a statistical correlation over 0.99 to 2x of the inverse of the daily performance of its benchmark. The Fund’s per Share NAV decrease of 17.5% for the three months ended September 30, 2012, as compared to the increase of 33.8% for the three months ended September 30, 2011, was primarily due to depreciation in the value of the assets of the Fund during the three months ended September 30, 2012.

During the three months ended September 30, 2012, the Fund’s per Share NAV reached its high for the period on July 2, 2012 at $50.63 per Share and reached its low for the period on September 14, 2012 at $35.28 per Share. By comparison, during the three months ended September 30, 2011, the Fund’s per Share NAV reached its high for the period on August 9, 2011 at $67.93 per Share and reached its low for the period on July 22, 2011 at $44.06 per Share.

The benchmark’s rise of 7.3% for the three months ended September 30, 2012, as compared to the benchmark’s decline of 18.3% for the three months ended September 30, 2011, can be attributed to an increase in the price of WTI Crude Oil during the three months ended September 30, 2012.

During the three months ended September 30, 2012, the increase in the Fund’s NAV resulted from an increase from 4,300,005 outstanding Shares at June 30, 2012 to 8,725,005 outstanding Shares at September 30, 2012.

The Fund’s per Share NAV decrease of 40.6% for the three months ended September 30, 2012, as compared to the increase of 154.2% for the three months ended September 30, 2011, was primarily due to a depreciation in the value of the assets of the Fund during the three months ended September 30, 2012.

The benchmark’s decline of 24.4% for the three months ended September 30, 2012, as compared to the benchmark’s rise of 45.4% for the three months ended September 30, 2011, can be attributed to a decline in prices of the futures contracts that made up the S&P 500 VIX Mid-Term Futures Index during the three months ended September 30, 2012.

The Fund’s per Share NAV decrease of 23.4% for the nine months ended September 30, 2012, as compared to the decrease of 45.4% for the nine months ended September 30, 2011, was primarily due to a lesser depreciation in the value of the assets of the Fund during the nine months ended September 30, 2012.

During the nine months ended September 30, 2012, the Fund’s per Share NAV reached its high for the period on July 19, 2012 at $49.25 per Share and reached its low for the period on June 28, 2012 at $23.36 per Share. By comparison, during the nine months ended September 30, 2011, the Fund’s per Share NAV reached its high for the period on April 29, 2011 at $63.90 per Share and reached its low for the period on September 30, 2011 at $27.31 per Share.

The benchmark’s decline of 9.8% for the nine months ended September 30, 2012, as compared to the benchmark’s decline of 22.3% for the nine months ended September 30, 2011, can be attributed to a lesser decrease in the price of WTI Crude Oil during the nine months ended September 30, 2012.

The following table provides summary performance information for the Fund for the nine months ended September 30, 2012 and 2011:

	Nine Months Ended September 30, 2012			Nine Months Ended September 30, 2011
NAV beginning of period	$	246,813,921		$	99,032,781

Percentage change in benchmark		23.0	%		(0.6	)%
Benchmark annualized volatility		31.0	%		63.8	%

During the nine months ended September 30, 2012, the decrease in the Fund’s NAV resulted from a decrease from 3,218,874 outstanding Shares at December 31, 2011 to 3,158,489 outstanding Shares at September 30, 2012. The decrease in the Fund’s NAV also resulted in part from the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to 2x of the inverse of the daily performance of silver bullion as measured by the U.S. Dollar fixing price for delivery in London. By comparison, during the nine months ended September 30, 2011, the increase in the Fund’s NAV resulted from an increase from 496,496 outstanding Shares at December 31, 2010 to 6,538,874 outstanding Shares at September 30, 2011. The increase in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to 2x of the inverse of the daily performance of silver bullion as measured by the U.S. Dollar fixing price for delivery in London.

For the nine months ended September 30, 2012 and 2011, the Fund’s daily performance had a statistical correlation over 0.99 to 2x of the inverse of the daily performance of its benchmark. The Fund’s per Share NAV decrease of 48.0% for the nine months ended September 30, 2012, as compared to the decrease of 59.1% for the nine months ended September 30, 2011 was primarily due to a lesser depreciation in the value of the assets of the Fund during the nine months ended September 30, 2012.

During the nine months ended September 30, 2012, the Fund’s per Share NAV reached its high for the period on January 3, 2012 at $73.38 per Share and reached its low for the period on September 28, 2012 at $39.88 per Share. By comparison, during the nine months ended September 30, 2011, the Fund’s per Share NAV reached its high for the period on January 25, 2011 at $255.54 per Share and reached its low for the period on August 22, 2011 at $54.63 per Share.

The benchmark’s rise of 23.0% for the nine months ended September 30, 2012, as compared to the benchmark’s decline of 0.6% for the nine months ended September 30, 2011, can be attributed to an increase in the price of spot silver in U.S. Dollar terms during the nine months ended September 30, 2012.

Fund Performance

The following table provides summary performance information for the Fund for the nine months ended September 30, 2012 and 2011:

	Nine Months Ended September 30, 2012			Nine Months Ended September 30, 2011
NAV beginning of period	$	221,131,994		$	207,685,813
NAV end of period	$	249,828,407		$	271,440,942
Percentage change in NAV		13.0	%		30.7	%

Shares outstanding end of period		6,049,294			6,566,671
Percentage change in Shares outstanding		12.0	%		48.7	%
Shares created		3,750,000			6,533,333

Percentage change in per Share NAV		0.8	%		(12.1	)%
Percentage change in benchmark		(1.4	)%		5.3	%
Benchmark annualized volatility		7.8	%		9.0	%

During the nine months ended September 30, 2012, the increase in the Fund’s NAV resulted primarily from an increase from 5,399,294 outstanding Shares at December 31, 2011 to 6,049,294 outstanding Shares at September 30, 2012. 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 inverse of the daily performance of the spot price of the Japanese Yen versus the U.S. Dollar. By comparison, during the nine months ended September 30, 2011, the increase in the Fund’s NAV resulted from an increase from 4,416,671 outstanding Shares at December 31, 2010 to 6,566,671 outstanding Shares at September 30, 2011. The increase in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to 2x of the inverse of the daily performance of the spot price of the Japanese Yen versus the U.S. Dollar.

For the nine months ended September 30, 2012 and 2011, the Fund’s daily performance had a statistical correlation over 0.99 to 2x of the inverse of the daily performance of its benchmark. The Fund’s per Share NAV increase of 0.8% for the nine months ended September 30, 2012, as compared to the decrease of 12.1% for the nine months ended September 30, 2011 was primarily due to an appreciation in the value of the assets held by the Fund during the nine months ended September 30, 2012.

During the nine months ended September 30, 2012, the Fund’s per Share NAV reached its high for the period on March 14, 2012 at $48.20 per Share and reached its low for the period on February 2, 2012 at $40.08 per Share. By comparison, during the nine months ended September 30, 2011, the Fund’s per Share NAV reached its high for the period on April 6, 2011 at $51.44 per Share and reached its low for the period on September 22, 2011 at $40.45 per Share.

The benchmark’s decline of 1.4% for the nine months ended September 30, 2012, as compared to the benchmark’s rise of 5.3% for the nine months ended September 30, 2011, can be attributed to a decline in the value of the Japanese Yen versus the U.S. Dollar during the nine months ended September 30, 2012.

During the nine months ended September 30, 2012, the increase in the Fund’s NAV resulted from an increase from 13,334 outstanding Shares at December 31, 2011 to 6,359,151 outstanding Shares at September 30, 2012. The increase in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to 2x of the daily performance of the S&P 500 VIX Short-Term Futures Index.

For the nine months ended September 30, 2012, the Fund’s daily performance had a statistical correlation over 0.99 to 2x of the daily performance of its benchmark.

During the nine months ended September 30, 2012, the Fund’s per Share NAV reached its high for the period on January 3, 2012 at $649.02 per Share and reached its low for the period on September 24, 2012 at $28.85 per Share.

The benchmark’s decline of 75.0% for the nine months ended September 30, 2012, can be attributed to decreasing prices of the near-term futures contracts on the VIX futures curve.

During the nine months ended September 30, 2012, the increase in the Fund’s NAV resulted from an increase from 400,005 outstanding Shares at December 31, 2011 to 8,725,005 outstanding Shares at September 30, 2012. The increase in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to the daily performance of the S&P 500 VIX Short-Term Futures Index. By comparison, during the nine months ended September 30, 2011, the increase in the Fund’s NAV resulted primarily from an increase from 5 outstanding Shares at December 31, 2010 to 250,005 outstanding Shares at September 30, 2011. The increase in the Fund’s NAV also resulted in part from the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to the daily performance of the S&P 500 VIX Short-Term Futures Index.

For the nine months ended September 30, 2012 and 2011, the Fund’s daily performance had a statistical correlation over 0.99 of the daily performance of its benchmark. The Fund’s per Share NAV decrease of 75.1% for the nine months ended September 30, 2012, as compared to the increase of 44.5% for the nine months ended September 30, 2011, was primarily due to a depreciation in the value of the assets of the Fund during the nine months ended September 30, 2012.

During the nine months ended September 30, 2012, the Fund’s per Share NAV reached its high for the period on January 3, 2012 at $71.63 per Share and reached its low for the period on September 24, 2012 at $18.38 per Share. By comparison, during the nine months ended September 30, 2011, the Fund’s per Share NAV reached its high for the period on September 30, 2011 at $115.59 per Share and reached its low for the period on July 7, 2011 at $43.15 per Share.

The benchmark’s decline of 75.0% for the nine months ended September 30, 2012, as compared to the benchmark’s rise of 47.1% for the nine months ended September 30, 2011, can be attributed to a decline in prices of the near-term futures contracts on the VIX futures curve during the nine months ended September 30, 2012.

During the nine months ended September 30, 2012, the increase in the Fund’s NAV resulted primarily from an increase from 1,225,005 outstanding Shares at December 31, 2011 to 2,425,005 outstanding Shares at September 30, 2012. The increase in the Fund’s NAV was offset by the cumulative effect of the Fund seeking daily investment results (before fees and expenses) that correspond to the daily performance of the S&P 500 VIX Mid-Term Futures Index. By comparison, during the nine months ended September 30, 2011, the increase in the Fund’s NAV resulted primarily from an increase from 5 outstanding Shares at December 31, 2010 to 150,005 outstanding Shares at September 30, 2011.

The benchmark’s decline of 43.8% for the nine months ended September 30, 2012, as compared to the benchmark’s rise of 12.9% for the nine months ended September 30, 2011, can be attributed to a decline in prices of the futures contracts that made up the S&P 500 VIX Mid-Term Futures Index during the nine months ended September 30, 2012.

The Fund’s net income decreased for the nine months ended September 30, 2012, as compared to the nine months ended September 30, 2011, primarily due to a decline in the Fund’s benchmark during the nine months ended September 30, 2012.

Off-Balance Sheet Arrangements and Contractual Obligations

As of November 9, 2012, 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. One officer of the Trust also serves as an officer and owner of the Sponsor.

Market Risk

Trading in futures contracts involves each Fund entering into contractual commitments to purchase or sell a commodity underlying the Fund’s benchmark at a specified date and price, should it hold such futures contract into the deliverable period. Should a Fund enter into a contractual commitment to sell a physical commodity, it would be 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.

-203-

Each Fund’s exposure to market risk is 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.

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 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.

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 a swap agreement defaults, the Fund’s risk of loss 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.

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;

• generally requiring that the counterparty posts collateral in amounts approximately equal to that owed to the Funds, as marked to market daily;

• 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.

The FCM for each Fund, in accepting orders for the purchase or sale of domestic futures contracts, is required by CFTC regulations to separately account for and segregate as belonging to the Fund, all assets of the Fund relating to domestic futures trading, and the FCM is not allowed to commingle such assets with other assets of the FCM. In addition, CFTC regulations also require the FCM to hold in a secure account assets of each Fund related to foreign futures trading.

-204-

The Funds could lose money if the issuer of a debt security is unable to meet its financial obligations or goes bankrupt. The Funds could also lose money if the issuer of a debt security in which it has a short position is upgraded or generally improves its standing. Changes in an issuer’s financial strength or in an issuer’s or debt security’s credit rating also may affect a security’s value and thus have an impact on a Fund’s performance. Credit risk usually applies to most debt securities.

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 or 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 Leveraged Funds, the Short Euro Fund, the Geared VIX Funds and the Matching VIX 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 Leveraged Funds’, Short Euro Fund’s, Geared VIX Funds’ and Matching VIX Funds’ final creation/redemption NAV for the three and nine months ended September 30, 2012.

Short-term investments are valued at market price. Treasury securities having a maturity of greater than sixty days are valued at market price.

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

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

The Funds disclose the fair value of their investments in a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. 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 or will pay its respective brokerage commissions, including applicable exchange fees, NFA fees, give-up fees, pit brokerage fees and other transaction related fees and expenses charged in connection with trading activities for each Fund’s investment in U.S. Commodity Futures Trading Commission regulated investments. Brokerage commissions on futures contracts are recognized on a half-turn basis. The Sponsor is currently paying the brokerage commissions on the VIX futures contracts for the Matching VIX Funds.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Since the ProShares Ultra DJ-UBS Natural Gas Fund, ProShares UltraShort DJ-UBS Natural Gas Fund, ProShares Short Euro, ProShares Ultra Australian Dollar, ProShares UltraShort Australian Dollar, ProShares Ultra VIX Short-Term Futures ETF and ProShares Short VIX Short-Term Futures ETF were not conducting operations as of September 30, 2011, comparisons of the positions in certain Financial Instruments for those funds as of September 30, 2011 have not been provided. As of September 30, 2012, each of the Managed Futures Funds had not commenced investment operations; therefore, these quantitative and qualitative disclosures about market risk do not include comparisons of positions in certain Financial Instruments for the Managed Futures Funds.

Quantitative Disclosure

Commodity Price Sensitivity

Each of the Commodity Funds and the Commodity Index Funds is exposed to commodity price risk through its holdings of Financial Instruments. The following tables provide information about each of the Commodity Funds’ and the Commodity Index Funds’ Financial Instruments, which were sensitive to commodity price risk. As of September 30, 2012 and, as applicable, September 30, 2011, each of the Commodity Funds and the Commodity Index Funds’ positions were as follows:

ProShares Ultra DJ-UBS Commodity:

As of September 30, 2012 and 2011, the ProShares Ultra DJ-UBS Commodity Fund was exposed to commodity price risk through its holding of swap agreements linked to the Dow Jones-UBS Commodity Index. The following tables provide information about the Fund’s swap positions as of September 30, 2012 and 2011, which were sensitive to commodity price risk.

Swap Agreements as of September 30, 2012

Reference Index	Counterparty	Long or Short		Index Close		Notional Amount at Value
DJ-UBS Commodity Index	Goldman Sachs International		Long	$	148.5061	$	11,686,812
DJ-UBS Commodity Index	UBS AG		Long		148.5061		5,108,198

Swap Agreements as of September 30, 2011

Reference Index	Counterparty	Long or Short	Index Close		Notional Amount at Value
DJ-UBS Commodity Index	Goldman Sachs International	Long	$	140.1750	$	6,650,383
DJ-UBS Commodity Index	UBS AG	Long		140.1750		16,811,409

The September 30, 2012 and 2011 swap notional amounts are calculated by multiplying units times the closing level of the Index. These notional amounts will increase (decrease) proportionally with increases (decreases) in the level of the Index. Additional gains (losses) associated with these contracts will be equal to any such subsequent increases (decreases) in notional amount, before accounting for spreads or financing costs associated with the swaps. 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 Trust’s Annual Report on Form 10-K for the year ended December 31, 2011 filed with the U.S. Securities and Exchange Commission (“SEC”) on February 29, 2012 (“the Form 10-K”), for additional information regarding performance for periods longer than one 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.

-207-

ProShares UltraShort DJ-UBS Commodity:

As of September 30, 2012 and 2011, the ProShares UltraShort DJ-UBS Commodity Fund was exposed to inverse commodity price risk through its holding of swap agreements linked to the Dow Jones-UBS Commodity Index. The following tables provide information about the Fund’s short swap positions as of September 30, 2012 and 2011, which were sensitive to commodity price risk.

Swap Agreements as of September 30, 2012

Reference Index	Counterparty	Long or Short	Index Close		Notional Amount at Value
DJ-UBS Commodity Index	Goldman Sachs International	Short	$	148.5061	$	(4,448,127	)
DJ-UBS Commodity Index	UBS AG	Short		148.5061		(1,319,410	)

DJ-UBS Commodity Index	UBS AG	Short		140.1750		(20,136,530	)

The September 30, 2012 and 2011 short swap notional amounts are calculated by multiplying units times the closing level of the Index. These short notional amounts will increase (decrease) proportionally with increases (decreases) in the level of the Index. Additional losses (gains) associated with these contracts will be equal to any such subsequent increases (decreases) in short notional amounts, before accounting for any spreads or financing costs associated with the swaps. The Fund will generally attempt to adjust its positions in Financial Instruments each day to have negative $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 negative two. See “Item 1A. Risk Factors” in the Form 10-K for additional information regarding performance for periods longer than one 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 Ultra DJ-UBS Crude Oil:

As of September 30, 2012 and 2011, the ProShares Ultra DJ-UBS Crude Oil Fund was exposed to commodity price risk through its holding of Crude Oil futures contracts and its holding of swap agreements linked to the Dow Jones-UBS WTI Crude Oil Sub-Index.

The September 30, 2012 and 2011 short futures notional amounts are calculated by multiplying the number of contracts held times the valuation price times the contract multiplier. The September 30, 2012 and 2011 short forward notional amounts equal units multiplied by the forward price. These short notional amounts will increase (decrease) proportionally with increases (decreases) in the price of the futures contract or forward price, as applicable. Additional losses (gains) associated with these contracts will be equal to any such subsequent increases (decreases) in short notional amounts, 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 negative $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 one day. Counterparty risk related to the forward agreements 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.

Each of the Currency Funds is exposed to exchange rate risk through its holdings of Financial Instruments. The following tables provide information about each of the Currency Fund’s Financial Instruments, which are sensitive to changes in exchange rates.

The September 30, 2012 futures notional amount is calculated by multiplying the number of contracts held times the valuation price times the contract multiplier. The notional amount will increase (decrease) proportionally with increases (decreases) in the price of the futures contract. Additional losses (gains) associated with these contracts will be equal to any such subsequent increases (decreases) in short notional amounts, 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 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. See “Item 1A. Risk Factors” in the Form 10-K for additional information regarding performance for periods longer than one day.

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 Ultra Fund seeks daily investment results (before fees and expenses) that correspond to twice (2x) the daily performance 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 twice the inverse (-2x) of the daily performance of its corresponding benchmark. Each Matching VIX Fund seeks investment results (before fees and expenses) that match the performance of a benchmark. The Geared Funds do not seek to achieve these stated investment objectives over a period of time greater than a single day because mathematical compounding prevents the Geared Funds from achieving such results. Performance over longer periods of time will be influenced not only by the cumulative period performance of the corresponding benchmark but equally by the intervening volatility of the benchmark as well as fees and expenses, including costs associated with the use of Financial Instruments such as financing costs and trading spreads. Future period returns, before fees and expenses, cannot be estimated simply by estimating the percent change in the corresponding benchmark and multiplying by two or negative two. 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 one day. The Matching VIX Funds and the Managed Futures Funds seek to achieve their stated investment objective 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 Ultra DJ-UBS Crude Oil and the ProShares UltraShort DJ-UBS Crude Oil Funds are exposed to are direct and inverse exposure, respectively, to the price of crude oil as measured by the return of holding and periodically rolling crude oil futures contracts (the Dow Jones-UBS 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.

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 a Short Fund or 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, -1x 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 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, its 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, subject to certain minimum thresholds.

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).

Part II. OTHER INFORMATION

Item 1. Legal Proceedings.

The Trust and certain principals of the Sponsor have been named as defendants (along with several other parties) in a consolidated class action lawsuit filed in the United States District Court for the Southern District of New York, styled In re ProShares Trust Securities Litigation, Civ. No. 09-cv-6935. The complaint, as amended, alleged that the defendants violated Sections 11 and 15 of the Securities Act of 1933 by including untrue statements of material fact and omitting material facts in the Registration Statement for one or more ProShares ETFs and allegedly failing to adequately disclose the Funds’ investment objectives and risks. The six Funds of the Trust named in the complaint were ProShares Ultra Silver, ProShares UltraShort Gold, ProShares Ultra Gold, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra DJ-UBS Crude Oil and ProShares UltraShort Silver. On September 10, 2012, the District Court issued an Opinion and Order dismissing the class action lawsuit in its entirety. On October 3, 2012, the plaintiffs filed a Notice of Appeal appealing the dismissal. The Trust believes the complaint is without merit and that the anticipated outcome will not adversely impact the operation of the Trust or any of its Funds. Accordingly, no loss contingency has been recorded in the balance sheet and the amount of loss, if any, cannot be reasonably estimated at this time.

Item 1A. Risk Factors.

There has not been a material change to the Risk Factors previously disclosed in the Trust’s Annual Report on Form 10-K for the year ended for the year ended December 31, 2011, filed on February 29, 2012 and in the Trust’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2012, filed on August 9, 2012.

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

(a) None.

(b) The Trust initially registered Shares on a Form S-1 (No. 333-146801), which was declared effective on November 21, 2008, and registered additional Shares on its Registration Statement on Form S-1 (No. 333-156888), which was declared effective on February 13, 2009. The Trust terminated these two offerings before the sale of all Shares registered and re-allocated the remaining amount of the Shares registered among the Funds listed on its Registration Statement on Form S-3 (No. 333-163511), which became effective on December 4, 2009 and registered additional Shares and/or added Funds pursuant to Post-Effective Amendments to that Registration Statement, 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 (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 (No. 333-163511) was declared effective, which registered additional Shares for ProShares Ultra DJ-UBS Crude Oil and terminated the offerings for certain other Funds. New offerings for certain of those Funds were registered on an accompanying Registration Statement on Form S-1 (No. 333-176878), which was also declared effective on June 26, 2012. On September 24, 2012, a Registration Statement on Form S-1 (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 (No. 333-183672) was a combined registration statement acting as a post-effective amendment to the Form S-1 (No. 333-176878), which offerings were terminated upon effectiveness. On September 27, 2012, a Registration Statement on Form S-3 (No. 333-183674) was declared effective, which registered additional Shares for ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Crude Oil and ProShares UltraShort Euro. This registration statement (No. 333-183674) was a combined registration statement acting as a post-effective amendment to the Form S-3 (No. 333-163511), which offerings were terminated upon effectiveness. On September 28, 2012, a post-effective amendment to an S-1 Registration Statement was declared effective, terminating the proposed offerings of ProShares Ultra Canadian Dollar, ProShares Ultra Swiss Franc, ProShares Short Yen, ProShares UltraShort Canadian Dollar and ProShares UltraShort Swiss Franc. Therefore, as of September 30, 2012, the Trust has four registration statements outstanding:

-226-

1) an effective Form S-3 registration statement (No. 333-183674); 2) an effective Form S-1 registration statement (No. 333-183672); 3) another effective Form S-1 registration statement (No. 333-178707); and 4) a Form S-1 registration statement that has not been declared effective (No. 333-178212).

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 be used to collateralize swap agreements or forward contracts or deposited with FCMs as margin in connection with any futures transactions. Each Geared Fund continuously offers and redeems or will continuously offer and redeem and each Managed Futures Fund will continuously offer and redeem its Shares in blocks of 50,000 Shares, and each Matching VIX Fund continuously offers and redeems Shares in blocks of 25,000 Shares. The Managed Futures Funds have not yet commenced investment operations.

NOTE 1—ORGANIZATION

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 currently organized into separate series (each, a “Fund” and collectively, the “Funds”). As of September 30, 2012, the following twenty-one series of the Trust have commenced investment operations: (i) ProShares Ultra DJ-UBS Commodity, ProShares UltraShort DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra DJ-UBS Natural Gas, ProShares UltraShort DJ-UBS Natural Gas, ProShares Ultra Gold, ProShares UltraShort Gold, ProShares Ultra Silver, ProShares UltraShort Silver, ProShares Ultra Australian Dollar, ProShares UltraShort Australian Dollar, ProShares Ultra Euro, ProShares UltraShort Euro, ProShares Ultra Yen and ProShares UltraShort Yen (each, a “Leveraged Fund” and collectively, the “Leveraged Funds”); (ii) ProShares Short Euro (the “Short Euro Fund”); (iii) ProShares Ultra VIX Short-Term Futures ETF and ProShares Short VIX Short-Term Futures ETF (each, a “Geared VIX Fund” and collectively, the “Geared VIX Funds”); and (iv) ProShares VIX Short-Term Futures ETF and ProShares VIX Mid-Term Futures ETF (each, a “Matching VIX Fund” and collectively, the “Matching VIX Funds”). 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 Leveraged Fund, Short Euro Fund, Geared VIX Fund or Matching VIX Fund. The Shares of each Leveraged Fund, the Short Euro Fund, each Geared VIX Fund and each Matching VIX Fund are listed on the New York Stock Exchange Archipelago (“NYSE Arca”).

The Trust has also registered shares for thirty-two additional series: (i) ProShares Short DJ-UBS Natural Gas and ProShares Short Gold (each, a “Short Fund” and collectively, the “Short Funds”); (ii) ProShares UltraShort VIX Short-Term Futures ETF, ProShares Ultra VIX Mid-Term Futures ETF, ProShares Short VIX Mid-Term Futures ETF and ProShares UltraShort VIX Mid-Term Futures ETF (each, a “New Geared VIX Fund” and collectively, the “New Geared VIX Funds”); (iii) ProShares Managed Futures Strategy, ProShares Commodity Managed Futures Strategy and ProShares Financial Managed Futures Strategy (each, a “Managed Futures Fund” and collectively, the “Managed Futures Funds”); (iv) ProShares UltraPro Australian Dollar, ProShares Short Australian Dollar, ProShares UltraPro Short Australian Dollar, ProShares UltraPro Canadian Dollar, ProShares Ultra Canadian Dollar, ProShares Short Canadian Dollar, ProShares UltraShort Canadian Dollar, ProShares UltraPro Short Canadian Dollar, ProShares UltraPro Euro, ProShares UltraPro Short Euro, ProShares UltraPro Swiss Franc, ProShares Ultra Swiss Franc, ProShares Short Swiss Franc, ProShares UltraShort Swiss Franc, ProShares UltraPro Short Swiss Franc, ProShares UltraPro Yen, ProShares Short Yen and ProShares UltraPro Short Yen (each, a “New Currency Fund” and collectively, the “New Currency Funds”); and (v) ProShares UltraPro U.S. Dollar, ProShares Ultra U.S. Dollar, ProShares Short U.S. Dollar, ProShares UltraShort U.S. Dollar and ProShares UltraPro Short U.S. Dollar (each, a “Currency Index Fund” and collectively, the “Currency Index Funds”). The Geared VIX Funds and the Matching VIX Funds are collectively referred to as the “VIX Funds” in these Notes to Financial Statements. 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.

On June 25, 2012, the registered offerings for ProShares UltraPro Australian Dollar, ProShares Short Australian Dollar, ProShares UltraPro Short Australian Dollar, ProShares UltraPro Canadian Dollar, ProShares Short Canadian Dollar, ProShares UltraPro Short Canadian Dollar, ProShares UltraPro Euro, ProShares UltraPro Short Euro, ProShares UltraPro Swiss Franc, ProShares Short Swiss Franc, ProShares UltraPro Short Swiss Franc, ProShares UltraPro Yen, ProShares UltraPro Short Yen and the Currency Index Funds, each of which had never been publicly offered, were terminated. On June 26, 2012, the registered offerings for the Short Funds and the New Geared VIX Funds, each of which had never been publicly offered, were terminated. On September 28, 2012, the registered offerings for ProShares Ultra Canadian Dollar, ProShares UltraShort Canadian Dollar, ProShares Ultra Swiss Franc, ProShares UltraShort Swiss Franc and ProShares Short Yen, each of which had never been publicly offered, were terminated. Thus, as of September 30, 2012, the only Funds that have remaining registered amounts are the Managed Futures Funds.

As of September 30, 2012, each of the Managed Futures Funds had seed capital, but none of the Managed Futures Funds had commenced investment operations; therefore, these Financial Statements do not include Schedules of Investments, Statements of Operations, Statements of Changes in Shareholders’ Equity or Statements of Cash Flows for the Managed Futures Funds.

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 Ultra DJ-UBS Commodity, ProShares UltraShort DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra Gold, ProShares UltraShort Gold, ProShares Ultra Silver, ProShares UltraShort Silver, ProShares Ultra Euro, ProShares UltraShort Euro, ProShares Ultra Yen and ProShares UltraShort Yen.

Eight of the Funds, ProShares Ultra DJ-UBS Commodity, ProShares UltraShort DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra Euro, ProShares UltraShort Euro, ProShares Ultra Yen and ProShares UltraShort Yen, commenced trading on the NYSE Arca on November 25, 2008. Four of the Funds, ProShares Ultra Gold, ProShares UltraShort Gold, ProShares Ultra Silver, and ProShares UltraShort Silver, commenced trading on the NYSE Arca on December 3, 2008. Two of the Funds, ProShares VIX Short-Term Futures ETF and ProShares VIX Mid-Term Futures ETF, commenced trading on the NYSE Arca on January 3, 2011. Two of the Funds, ProShares Ultra VIX Short-Term Futures ETF and ProShares Short VIX Short-Term Futures ETF, commenced trading on the NYSE Arca on October 3, 2011. Two of the Funds, ProShares Ultra DJ-UBS Natural Gas and ProShares UltraShort DJ-UBS Natural Gas, commenced trading on the NYSE Arca on October 4, 2011. One of the Funds, ProShares Short Euro, commenced trading on the NYSE Arca on June 26, 2012. Two of the Funds, ProShares Ultra Australian Dollar and ProShares UltraShort Australian Dollar, commenced trading on the NYSE Arca on July 17, 2012. As of September 30, 2012, the Managed Futures Funds had not yet commenced trading.

Groups of Funds are collectively referred to in several different ways. References to “Ultra Funds,” “Short Funds” or “UltraShort 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. References to “Managed Futures Funds” refer to the different Funds according to which index the Fund intends to gain exposure.

Each “Ultra” Fund seeks daily investment results (before fees and expenses) that correspond to twice (2x) the daily performance 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 twice the inverse (-2x) of the daily performance of its corresponding benchmark. Daily performance is measured from the calculation of one NAV to the next.

Each of the Geared Funds generally invests in Financial Instruments (i.e., commodity-based, currency-based or equity market volatility-based instruments whose value is derived from the value of an underlying asset, rate or index, including futures contracts and options on futures contracts, swap agreements, forward contracts and other commodity-based or currency-based options contracts) as a substitute for investing directly in commodities, currencies, or equity market volatility products in order to gain exposure to the commodity index, currency benchmark, commodity, currency or to an equity market volatility index. Financial Instruments also are used to produce economically “leveraged” or “inverse” investment results for the Funds. Each Matching VIX Fund seeks daily investment results (before fees and expenses) that match the performance of a benchmark. Each Geared VIX Fund seeks daily investment results (before fees and expenses) that correspond to a multiple, the inverse or inverse multiple of the daily performance of a benchmark. 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”). The Managed Futures Funds will seek to provide investment results (before fees and expenses) that correspond to the performance of the S&P Dynamic Futures Index (the “DFI” or the “Index”), the S&P Dynamic Commodities Futures Index (the “DCFI”) or the S&P Dynamic Financial Futures Index (the “DFFI”) (each a “Sub-Index” and collectively, the “Sub-Indexes”). Each Managed Futures Fund intends to obtain exposure to the Index or to a Sub-Index, as applicable, by investing primarily in unleveraged positions in U.S. exchange-traded futures contracts on sixteen different tangible commodities (the “Commodity Futures Contracts”) or futures contracts on eight different financials, such as major currencies and U.S. Treasury securities (the “Financial Futures Contracts” and together with the Commodity Futures Contracts, the “Index Components”).

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 one day should not be expected to be a simple multiple (e.g., 2x, -1 or -2x) of the period return of the corresponding benchmark and will likely differ significantly. The Matching VIX Funds and the Managed Futures Funds seek to achieve their stated investment objective both over a single day and over time.

ProShares Ultra DJ-UBS Commodity, ProShares UltraShort DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra DJ-UBS Natural Gas and ProShares UltraShort DJ-UBS 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.

Renaming of Index

Effective as of January 2, 2012, the official name for the Dow Jones-UBS Crude Oil Sub-Index^SM (Ticker: DJUBSCL) changed to the Dow Jones-UBS WTI Crude Oil Sub-Index^SM. The ticker did not change as a result of the name change.

Share Splits and Reverse Share Splits

Prior to the opening of trading on the NYSE Arca on February 25, 2011, ProShares UltraShort DJ-UBS Commodity and ProShares UltraShort DJ-UBS Crude Oil executed a 1-for-5 reverse split of Shares and ProShares UltraShort Silver and ProShares Ultra DJ-UBS Crude Oil executed a 1-for-4 reverse split of Shares.

Prior to the opening of trading on the NYSE Arca on October 13, 2011, ProShares Ultra Silver executed a 2-for-1 split of Shares and ProShares UltraShort Yen executed a 1-for-3 reverse split of Shares. The funds traded at their post-split prices on October 13, 2011. The ticker symbols for the funds did not change, and they continue to trade on the NYSE Arca.

The fund traded at its post-split price on March 8, 2012. The ticker symbol for the fund did not change, and it continues to trade on the NYSE Arca.

Prior to the opening of trading on the NYSE Arca on May 11, 2012, ProShares UltraShort DJ-UBS Natural Gas executed a 3-for-1 split of Shares and ProShares Ultra DJ-UBS Natural Gas and ProShares UltraShort Silver executed a 1-for-5 reverse split of Shares. The funds traded at their post-split prices on May 11, 2012. The ticker symbols for the funds did not change, and they continue to trade on the NYSE Arca.

Prior to the opening of trading on the NYSE Arca on September 7, 2012, ProShares Ultra VIX Short-Term Futures ETF executed a 1-for-10 reverse split of Shares. The fund traded at its post-split price on September 7, 2012. The ticker symbol for the fund did not change, and it continues to trade on the NYSE Arca.

The reverse splits were applied retroactively for all periods presented, reducing the number of Shares outstanding for each of ProShares UltraShort DJ-UBS Commodity, ProShares UltraShort DJ-UBS Crude Oil, ProShares UltraShort Silver, ProShares Ultra DJ-UBS Crude Oil, ProShares UltraShort Yen, ProShares Ultra VIX Short-Term Futures ETF and ProShares Ultra DJ-UBS Natural Gas, 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 split.

The splits were applied retroactively for all periods presented, increasing the number of Shares outstanding for ProShares Ultra Silver and ProShares UltraShort DJ-UBS Natural Gas, 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.

Legal Proceedings

NOTE 9—LEGAL PROCEEDINGS

The Trust and certain principals of the Sponsor have been named as defendants (along with several other parties) in a consolidated class action lawsuit filed in the United States District Court for the Southern District of New York, styled In re ProShares Trust Securities Litigation, Civ. No. 09-cv-6935. The complaint, as amended, alleged that the defendants violated Sections 11 and 15 of the Securities Act of 1933 by including untrue statements of material fact and omitting material facts in the Registration Statement for one or more ProShares ETFs and allegedly failing to adequately disclose the Funds’ investment objectives and risks. The six Funds of the Trust named in the complaint were ProShares Ultra Silver, ProShares UltraShort Gold, ProShares Ultra Gold, ProShares UltraShort DJ-UBS Crude Oil, ProShares Ultra DJ-UBS Crude Oil and ProShares UltraShort Silver. On September 10, 2012, the District Court issued an Opinion and Order dismissing the class action lawsuit in its entirety. On October 3, 2012, the plaintiffs filed a Notice of Appeal appealing the dismissal. The Trust believes the complaint is without merit and that the anticipated outcome will not adversely impact the operation of the Trust or any of its Funds. Accordingly, no loss contingency has been recorded in the balance sheet and the amount of loss, if any, cannot be reasonably estimated at this time.

Subsequent Events

NOTE 10—SUBSEQUENT EVENTS

Management has evaluated the possibility of subsequent events existing in the Trust’s and the Funds’ financial statements through the date the financial statements were issued. The subsequent events were as follows:

On September 20, 2012, the Trust announced a 2-for-1 split of the Shares of beneficial interest of ProShares Short VIX Short-Term Futures (NYSE Arca symbol “SVXY”). Prior to the opening of trading on the NYSE Arca on October 5, 2012, ProShares Short VIX Short-Term Futures executed a 2-for-1 split of Shares.

The split was effective for shareholders of record after the close of the markets on October 2, 2012, and payable after the close of the markets on October 4, 2012. The fund traded at its post-split price on October 5, 2012. The ticker symbol for the Fund did not change, and it continues to trade on the NYSE Arca.

The split was applied retroactively for all periods presented, increasing the number of Shares outstanding for ProShares Short VIX Short-Term Futures, and resulted in a proportionate decrease in the price per Share and per Share information of ProShares Short VIX Short-Term Futures. Therefore, the split did not change the aggregate net asset value of a shareholder’s investment at the time of the split.

On September 20, 2012, the Trust announced a 1-for-4 reverse split of the Shares of beneficial interest of ProShares UltraShort Gold (NYSE Arca symbol “GLL”). Prior to the opening of trading on the NYSE Arca on October 5, 2012, ProShares UltraShort Gold executed a 1-for-4 reverse split of Shares.

The reverse split was effective for shareholders of record after the close of the markets on October 4, 2012. The fund traded at its post-split price on October 5, 2012. The ticker symbol for the Fund did not change, and it continues to trade on the NYSE Arca.

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

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 that the Sponsor believes in combination should produce returns consistent with a Fund’s objective.

All open derivative positions at period-end for each Fund are disclosed in the Schedule of Investments and the notional value of these open positions relative to the shareholders’ equity of each Fund is generally representative of the notional value of open positions to shareholders’ equity throughout the reporting period for each respective Fund. The volume associated with derivative positions varies on a daily basis as each Fund transacts derivative contracts in order to achieve the appropriate exposure, as expressed in notional value, in comparison to shareholders’ equity consistent with each Fund’s investment objective.

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 effected. The initial margin is segregated as cash 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. 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.

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) commodities/indices, or to create an economic hedge against a position. Swap agreements are two-party contracts entered into primarily with major global financial institutions for a specified period, ranging from a day to more than one year. 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. In the case of futures contracts based indices, such as those used by the Commodity Index Funds, the reference interest rate is zero. 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 an Ultra Fund, the Ultra Fund would be entitled to settlement payments in the event the benchmark increases and would be required to make payments to the swap counterparties in the event 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 an UltraShort Fund, the UltraShort Fund would be required to make payments to the swap counterparties in the event the benchmark increases and would be entitled to settlement payments in the event 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 swap agreement is accrued on a daily basis and an amount of cash and/or securities having an aggregate NAV at least equal to such accrued excess is maintained in a segregated account by the Funds’ 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 Index.

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 (commodity price 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 an imperfect correlation 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 counterparty. A Fund will 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 September 30, 2012 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. 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 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 September 30, 2012, the collateral posted by counterparties consisted of cash and U.S. Treasury Securities.

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 the over-the-counter (“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 are, in general, not cleared or guaranteed by a third party. The Funds may collateralize 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 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 September 30, 2012, the collateral posted by counterparties consisted of cash and 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 that their counterparties post margin.

A Fund will 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.

Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2012

Use Of Estimates & Indemnifications

Use of Estimates & Indemnifications

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts 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.

Statement Of Cash Flows

Statement of Cash Flows

The cash amount shown in the Statements of Cash Flows is the amount reported as cash in the Statement of Financial Condition dated September 30, 2012, and represents non-segregated cash with the custodian and does not include short-term investments.

Final Net Asset Value For Fiscal Period

Final Net Asset Value for Fiscal Period

The times of the calculation of the Leveraged Funds’, the Short Euro Fund’s, the Geared VIX Funds’ and the Matching VIX Funds’ final net asset value for creation and redemption of fund Shares for the three months ended September 30, 2012 were as follows. All times are Eastern Standard Time:

	NAV Calculation Time		NAV Calculation Date
Ultra Silver, UltraShort Silver		7:00 A.M.		September 30
Ultra Gold, UltraShort Gold		10:00 A.M.		September 30
Ultra DJ-UBS Commodity, UltraShort DJ-UBS Commodity		2:30 P.M.		September 30
Ultra DJ-UBS Crude Oil, UltraShort DJ-UBS Crude Oil		2:30 P.M.		September 30
Ultra DJ-UBS Natural Gas, UltraShort DJ-UBS Natural Gas		2:30 P.M.		September 30
Ultra Australian Dollar, UltraShort Australian Dollar		4:00 P.M.		September 30
Ultra Euro, Short Euro, UltraShort Euro		4:00 P.M.		September 30
Ultra Yen, UltraShort Yen		4:00 P.M.		September 30
Ultra VIX Short-Term Futures ETF, VIX Short-Term Futures ETF, Short VIX Short-Term Futures ETF, VIX Mid-Term Futures ETF		4:15 P.M.		September 30

Although the Leveraged Funds’, the Short Euro Fund, the Geared VIX Funds’ and the Matching VIX 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 September 30, 2012.

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 Leveraged Funds, the Short Euro Fund, the Geared VIX Funds and the Matching VIX 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 Leveraged Funds’, Short Euro Fund’s, Geared VIX Funds’ and Matching VIX Funds’ final creation/redemption NAV for the three months ended September 30, 2012.

Investment Valuation

Investment Valuation

Short-term investments are valued at market price. Treasury securities having a maturity of greater than sixty days are valued at market price. In each of these situations, valuations are typically categorized as Level I in the fair value hierarchy.

Derivatives (futures contracts, swap agreements, forward agreements and foreign currency forward contracts) are generally valued using independent sources and/or agreements with counterparties or other procedures as determined by the Sponsor. Futures contracts, except for those entered into by the Gold, Silver, Australian Dollar and Short Euro Funds, are generally valued at the last settled price on the applicable exchange on which that future trades. Futures contracts entered into by the Gold, Silver, Australian Dollar and Short Euro Funds are valued at the last sales price prior to the time at which the NAV per Share of a Fund is determined. For financial reporting purposes, all futures contracts are valued at last settled price. 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 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. 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 Leveraged Funds’, the Short Euro Fund’s, the Geared VIX Funds’ and the Matching VIX Funds’ policies are intended to result in a calculation of a Leveraged Fund’s, the Short Euro Fund’s, a Geared VIX Fund’s or a Matching VIX Fund’s NAV that fairly reflects investment values as of the time of pricing, a Leveraged Fund, the Short Euro Fund, a Geared VIX Fund or a Matching VIX 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 a Leveraged Fund, the Short Euro Fund, a Geared VIX Fund or a Matching 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.

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.

The following table summarizes the valuation of investments at September 30, 2012 using the fair value hierarchy:

Investment Transactions And Related Income

Investment Transactions and Related Income

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

Brokerage Commissions And Fees

Brokerage Commissions and Fees

Each Fund pays or will pay 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 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. For the nine months ended September 30, 2012, the Sponsor paid and is currently paying brokerage commissions on VIX futures contracts for the Matching VIX Funds.

Federal Income Tax

Federal Income Tax

Each Fund is registered as a series of a Delaware statutory trust and is or will be 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 or will be 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 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.

Organization And Offering Costs

NOTE 5—ORGANIZATION AND OFFERING COSTS

Organization costs are expensed as incurred and offering costs will be amortized by the Funds over a twelve month period on a straight-line basis.

The Sponsor did not and will not charge its Management Fee in the first year of operations of each Leveraged Fund, the Short Euro Fund, each Geared VIX Fund or each Matching VIX Fund in an amount equal to the organization and offering costs. The Sponsor reimbursed or will reimburse each Fund to the extent that its organization and offering costs exceeded 0.95% of each Leveraged Fund’s, the Short Euro Fund’s or each Geared VIX Fund’s and 0.85% of each Matching VIX Fund’s average daily NAV for the first year of operations.

The Sponsor will not charge its Management Fee in the first year of operations of each Fund in an amount equal to the offering costs. The Sponsor has agreed to reimburse each Managed Futures Fund to the extent that its offering costs exceed 0.95% of its average daily NAV for the first year of operations. At September 30, 2012, amounts payable for offering costs are reflected in the Statement of Financial Condition for each Managed Futures Fund.

Creation And Redemption Of Creation Units

9 Months Ended

Sep. 30, 2012

Creation And Redemption Of Creation Units

NOTE 6—CREATION AND REDEMPTION OF CREATION UNITS

Each Fund issues and redeems or will issue and redeem Shares from time to time, but only in one or more Creation Units. A Creation Unit is or will be a block of 50,000 Shares of a Geared Fund or a Managed Futures 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. Authorized Participants also may pay a variable transaction fee to the Fund of up to 0.10% 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 and nine months ended September 30, 2012, which are included in the Sale 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 one day (as measured from NAV calculation time to NAV calculation time), and not for any other period. The return of a Geared Fund for a period longer than a day is the result of its return for each day compounded over the period and usually will differ from the multiple (2x), the inverse (-1x) or the inverse multiple (-2x) of the return of the Geared Fund’s benchmark for the period. A Fund will lose money if its index performance is flat over time, and it is possible for a Geared Fund to lose money over time even if the performance of its index increases (or decreases in the case of UltraShort or Short Funds), as a result of daily rebalancing, the benchmark’s volatility and compounding. Longer holding periods, higher index volatility 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 index. The Matching VIX Funds and Managed Futures Funds seek to achieve their stated investment objective both over a single day and over time.

Each Ultra or 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 twice as volatile on a daily basis as is the return of a fund with an objective of matching the same benchmark. The daily return of an UltraShort Fund with a -2x multiple is designed to return twice 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 instruments held by a Fund, such as swaps, futures contracts and/or forward contracts, and the performance of the applicable underlying indices, commodities or currencies; (3) bid-ask spreads on such instruments; (4) fees, expenses, transaction costs, financing costs associated with the use of derivatives 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; and (10) accounting standards.

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 over- or under-exposed to the benchmark may prevent such 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 (e.g., 2x or -2x) 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.

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 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.

Swap agreements and forward contracts are generally traded over the counter and are essentially unregulated by the CFTC. Investors, therefore, do not receive the protection of CFTC regulation or the statutory scheme of the CEA in connection with each Fund’s swap agreements or forward contracts. The lack of regulation in these markets could expose investors to significant losses under certain circumstances including in the event of trading abuses or financial failure by participants.

Unlike in futures contracts, the counterparty to 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 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. 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.

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.

Although the counterparty to a futures contract is often a clearing organization backed by a group of financial institutions, there may also be instances in which the counterparty could fail to perform its obligations, causing significant losses to a Fund.

Leverage Risk

The 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 Ultra and UltraShort Funds include a two times (2x) or two times the inverse (-2x) multiplier, a single-day movement in the relevant benchmark approaching 50% at any point in the day could result in the total loss or almost total loss of an investor’s investment if that movement is contrary to the investment objective of the Fund in which an investor has invested, even if such Fund’s benchmark subsequently moves in an opposite direction, eliminating all or a portion of the movement. This would be the case with downward single-day or intraday movements in the underlying benchmark of an Ultra Fund or upward one-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 August 2012 may specify an October 2012 expiration. For an Ultra Fund and a Matching VIX Fund, as that contract nears expiration, it may be replaced by selling the October 2012 contract and purchasing the contract expiring in December 2012. 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 October 2012 contract would take place at a price that is higher than the price at which the December 2012 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 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.

Significant Accounting Policies

NOTE 2—SIGNIFICANT ACCOUNTING POLICIES

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 U.S. Securities and Exchange Commission (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, 2011, as filed with the SEC on February 29, 2012.

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 September 30, 2012, and represents non-segregated cash with the custodian and does not include short-term investments.

Final Net Asset Value for Fiscal Period

The times of the calculation of the Leveraged Funds’, the Short Euro Fund’s, the Geared VIX Funds’ and the Matching VIX Funds’ final net asset value for creation and redemption of fund Shares for the three months ended September 30, 2012 were as follows. All times are Eastern Standard Time:

	NAV Calculation Time		NAV Calculation Date
Ultra Silver, UltraShort Silver		7:00 A.M.		September 30
Ultra Gold, UltraShort Gold		10:00 A.M.		September 30
Ultra DJ-UBS Commodity, UltraShort DJ-UBS Commodity		2:30 P.M.		September 30
Ultra DJ-UBS Crude Oil, UltraShort DJ-UBS Crude Oil		2:30 P.M.		September 30
Ultra DJ-UBS Natural Gas, UltraShort DJ-UBS Natural Gas		2:30 P.M.		September 30
Ultra Australian Dollar, UltraShort Australian Dollar		4:00 P.M.		September 30
Ultra Euro, Short Euro, UltraShort Euro		4:00 P.M.		September 30
Ultra Yen, UltraShort Yen		4:00 P.M.		September 30
Ultra VIX Short-Term Futures ETF, VIX Short-Term Futures ETF, Short VIX Short-Term Futures ETF, VIX Mid-Term Futures ETF		4:15 P.M.		September 30

Although the Leveraged Funds’, the Short Euro Fund, the Geared VIX Funds’ and the Matching VIX 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 September 30, 2012.

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 Leveraged Funds, the Short Euro Fund, the Geared VIX Funds and the Matching VIX 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 Leveraged Funds’, Short Euro Fund’s, Geared VIX Funds’ and Matching VIX Funds’ final creation/redemption NAV for the three months ended September 30, 2012.

Investment Valuation

Short-term investments are valued at market price. Treasury securities having a maturity of greater than sixty days are valued at market price. In each of these situations, valuations are typically categorized as Level I in the fair value hierarchy.

Derivatives (futures contracts, swap agreements, forward agreements and foreign currency forward contracts) are generally valued using independent sources and/or agreements with counterparties or other procedures as determined by the Sponsor. Futures contracts, except for those entered into by the Gold, Silver, Australian Dollar and Short Euro Funds, are generally valued at the last settled price on the applicable exchange on which that future trades. Futures contracts entered into by the Gold, Silver, Australian Dollar and Short Euro Funds are valued at the last sales price prior to the time at which the NAV per Share of a Fund is determined. For financial reporting purposes, all futures contracts are valued at last settled price. 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 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. 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 Leveraged Funds’, the Short Euro Fund’s, the Geared VIX Funds’ and the Matching VIX Funds’ policies are intended to result in a calculation of a Leveraged Fund’s, the Short Euro Fund’s, a Geared VIX Fund’s or a Matching VIX Fund’s NAV that fairly reflects investment values as of the time of pricing, a Leveraged Fund, the Short Euro Fund, a Geared VIX Fund or a Matching VIX 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 a Leveraged Fund, the Short Euro Fund, a Geared VIX Fund or a Matching 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.

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 or will pay 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 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. For the nine months ended September 30, 2012, the Sponsor paid and is currently paying brokerage commissions on VIX futures contracts for the Matching VIX Funds.

Federal Income Tax

Each Fund is registered as a series of a Delaware statutory trust and is or will be 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 or will be 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 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.
