Organization | NOTE 1 – ORGANIZATION ProShares Trust II (formerly known as the Commodities and Currencies Trust) (the “Trust”) is a Delaware statutory trust formed on October 9, 2007 and is currently organized into separate series (each, a “Fund” and collectively, the “Funds”). As of March 31, 2014, the following twenty-one series of the Trust have commenced investment operations: (i) ProShares UltraShort DJ-UBS Commodity, ProShares UltraShort DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Natural Gas, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Australian Dollar, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares Ultra DJ-UBS Natural Gas, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Australian Dollar, ProShares Ultra Euro and ProShares Ultra 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 Leveraged Funds, the Short Euro Fund and the Geared VIX Funds, are collectively referred to as the “Geared Funds” in these Notes to Financial Statements. The Geared VIX Funds and the Matching VIX Funds are collectively referred to as the “VIX Funds” in these Notes to Financial Statements. The Trust registered shares for thirty-two additional series: (i) ProShares Short DJ-UBS Natural Gas and ProShares Short Gold (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 (collectively, the “New Geared VIX Funds”); (iii) ProShares Managed Futures Strategy and ProShares Commodity Managed Futures Strategy (each, a “Managed Futures Fund” and collectively, the “Managed Futures Funds”); (iv) ProShares Financial Managed Futures Strategy; (v) 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; and (vi) 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 (collectively, the “Currency Index Funds”). The thirty-two additional series were never publicly offered and their registration has subsequently been terminated. Thus, as of March 31, 2014, the only Funds that have registered amounts are the twenty-one series of the Trust that have commenced investment operations. The Trust had no operations prior to November 24, 2008, other than matters relating to its organization, the registration of each series under the Securities Act of 1933, as amended, and the sale and issuance to ProShare Capital Management LLC (the “Sponsor”) of fourteen Shares at an aggregate purchase price of $350 in each of the following Funds: ProShares UltraShort DJ-UBS Commodity, ProShares UltraShort DJ-UBS Crude Oil, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen. Groups of Funds are collectively referred to in several different ways. References to “Short Funds,” “UltraShort Funds,” or “Ultra Funds” refer to the different Funds based upon their investment objectives, but without distinguishing among the Funds’ benchmarks. References to “Commodity Index Funds,” “Commodity Funds” and “Currency Funds” refer to the different Funds according to their general benchmark categories without distinguishing among the Funds’ investment objectives or Fund-specific benchmarks. References to “VIX Funds” refer to the different Funds based upon their investment objective and their general benchmark categories. Each “Short” Fund seeks daily investment results (before fees and expenses) that correspond to the inverse (-1x) of the daily performance of its corresponding benchmark. Each “UltraShort” Fund seeks daily investment results (before fees and expenses) that correspond to two times the inverse (-2x) of the daily performance of its corresponding benchmark. Each “Ultra” Fund seeks daily investment results (before fees and expenses) that correspond to two times (2x) the daily performance of its corresponding benchmark. Each Matching VIX Fund seeks investment results (before fees and expenses), both over a single day and over time, that match the performance of its corresponding benchmark. Daily performance is measured from the calculation of one NAV to the next. Each of the Funds generally invests in Financial Instruments (i.e., instruments whose value is derived from the value of an underlying asset, rate or index, including futures contracts, swap agreements, forward contracts and other instruments) as a substitute for investing directly in commodities, currencies, or spot volatility products in order to gain exposure to the commodity futures index, commodity, currency or exchange rate, equity volatility index or applicable commodity or financial futures contracts. Financial Instruments also are used to produce economically “inverse”, “inverse leveraged” or “leveraged” investment results for the Geared Funds. The Geared Funds do not seek to achieve their stated investment objective over a period of time greater than a single day because mathematical compounding prevents the Geared Funds from achieving such results. Accordingly, results over periods of time greater than a single day should not be expected to be a simple multiple (e.g., -1x, -2x or 2x) of the period return of the corresponding benchmark and will likely differ significantly. The Matching VIX Funds seek to achieve their stated investment objective both over a single day and over time. Share Splits and Reverse Share Splits The table below includes Share splits and reverse Share splits for the Funds during the three months ended March 31, 2014 and year ended December 31, 2013. The ticker symbols for these Funds did not change and each Fund 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 Natural Gas, ProShares Ultra Silver, ProShares VIX Short-Term Futures ETF and ProShares Ultra VIX Short-Term Futures ETF, and resulted in a proportionate increase in the price per Share and per Share information of each such Fund. Therefore, the reverse splits did not change the aggregate net asset value of a shareholder’s investment at the time of the reverse split.
