Organization | 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 March 31, 2013, 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 also registered shares for three additional series; ProShares UltraPro Short Euro, ProShares Managed Futures Strategy and ProShares Commodity Managed Futures Strategy, collectively referred to as the “New Funds”. As of March 31, 2013, each of the New Funds had seed capital, but none of these Funds had commenced investment operations. On April 24 2013, the registered offerings for each of the New Funds, which had never been publicly offered, were terminated. 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. Eight of the Funds, ProShares UltraShort DJ-UBS Commodity, ProShares UltraShort DJ-UBS Crude Oil, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil, ProShares Ultra Euro and ProShares Ultra Yen commenced trading on the NYSE Arca on November 25, 2008. Four of the Funds, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares Ultra Gold and ProShares Ultra 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 UltraShort DJ-UBS Natural Gas and ProShares Ultra 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 UltraShort Australian Dollar and ProShares Ultra Australian Dollar, commenced trading on the NYSE Arca on July 17, 2012. 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. 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 “leveraged,” “inverse” or “inverse leveraged” investment results for the Geared Funds. Each Matching VIX Fund seeks results (before fees and expenses), both over a single day and over time, that match the performance of the S&P 500 VIX Short-Term Futures Index (the “Short-Term VIX Index”) or the S&P 500 VIX Mid-Term Futures Index (the “Mid-Term VIX Index”) (each a “VIX Futures Index”). Each Geared VIX Fund seeks daily investment results (before fees and expenses) that correspond to a multiple or the inverse of the daily performance of 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 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. ProShares UltraShort DJ-UBS Commodity, ProShares UltraShort DJ-UBS Crude Oil, ProShares UltraShort DJ-UBS Natural Gas, ProShares Ultra DJ-UBS Commodity, ProShares Ultra DJ-UBS Crude Oil and ProShares Ultra 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 Subindex SM (Ticker: DJUBSCL) changed to the Dow Jones-UBS WTI Crude Oil Subindex SM. The ticker did not change as a result of the name change. Share Splits and Reverse Share Splits The table below includes Share splits and reverse Share splits for the Funds during the years ended December 31, 2012 and 2011. The ticker symbols for these Funds did not change, and each Fund continues to trade on the NYSE Arca.
