Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization | NOTE 1 – ORGANIZATION ProShares Trust II (formerly known as the Commodities and Currencies Trust) (the “Trust”) is a Delaware statutory trust formed on October 9, 2007 and is currently organized into separate series (each, a “Fund” and collectively, the “Funds”). As of September 30, 2017, the following twenty series of the Trust have commenced investment operations: (i) ProShares VIX Short-Term Futures ETF and ProShares VIX Mid-Term Futures ETF (each, a “Matching VIX Fund” and collectively, the “Matching VIX Funds”); (ii) ProShares Short VIX Short-Term Futures ETF and ProShares Ultra VIX Short-Term Futures ETF (each, a “Geared VIX Fund” and collectively, the “Geared VIX Funds”); (iii) ProShares UltraShort Bloomberg Crude Oil, ProShares UltraPro 3x Short Crude Oil ETF, ProShares UltraShort Bloomberg Natural Gas, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Australian Dollar, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Crude Oil, ProShares UltraPro 3x Crude Oil ETF , ProShares Ultra Bloomberg Natural Gas, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen (each, a “Leveraged Fund” and collectively, the “Leveraged Funds”); and (iv) ProShares Short Euro (the “Short Euro Fund”). Each of the Funds listed above issues common units of beneficial interest (“Shares”), which represent units of fractional undivided beneficial interest in and ownership of only that Fund. The Shares of each Fund are listed on the New York Stock Exchange Archipelago (“NYSE Arca”). The Leveraged Funds, the Short Euro Fund and the Geared VIX Funds, are collectively referred to as the “Geared Funds” in these Notes to Financial Statements. The Geared VIX Funds and the Matching VIX Funds are collectively referred to as the “VIX Funds” in these Notes to Financial Statements. The Trust had no operations prior to November 24, 2008, other than matters relating to its organization, the registration of each series under the Securities Act of 1933, as amended, and the sale and issuance to ProShare Capital Management LLC (the “Sponsor”) of fourteen Shares at an aggregate purchase price of $350 in each of the following Funds: ProShares UltraShort Bloomberg Crude Oil, ProShares UltraShort Gold, ProShares UltraShort Silver, ProShares UltraShort Euro, ProShares UltraShort Yen, ProShares Ultra Bloomberg Crude Oil, ProShares Ultra Gold, ProShares Ultra Silver, ProShares Ultra Euro and ProShares Ultra Yen. Groups of Funds are collectively referred to in several different ways. References to “Short Funds,” “UltraShort Funds,” or “Ultra Funds” refer to the different Funds based upon their investment objectives, but without distinguishing among the Funds’ benchmarks. References to “Commodity Index Funds,” “Commodity Funds” and “Currency Funds” refer to the different Funds according to their general benchmark categories without distinguishing among the Funds’ investment objectives or Fund-specific benchmarks. References to “VIX Funds” refer to the different Funds based upon their investment objective and their general benchmark categories. Each “Short” Fund seeks daily investment results (before fees and expenses) that correspond to the inverse (-1x) of the daily performance of its corresponding benchmark. Each “UltraShort” Fund seeks daily investment results (before fees and expenses) that correspond to two times the inverse (-2x) of the daily performance of its corresponding benchmark. Each “Ultra” Fund seeks daily investment results (before fees and expenses) that correspond to two times (2x) the daily performance of its corresponding benchmark. Each Matching VIX Fund seeks investment results (before fees and expenses), both over a single day and over time, that match the performance of its corresponding benchmark. Daily performance is measured from the calculation of one NAV to the next. The Geared Funds do not seek to achieve their stated investment objective over a period of time greater than a single day because mathematical compounding prevents the Geared Funds from achieving such results. Accordingly, results over periods of time greater than a single day should not be expected to be a simple multiple (e.g., -1x, -2x or 2x) of the period return of the corresponding benchmark and will likely differ significantly. Each of the Funds generally invests in Financial Instruments (i.e., instruments whose value is derived from the value of an underlying asset, rate or index, including futures contracts, swap agreements, forward contracts and other instruments) as a substitute for investing directly in commodities, currencies, or spot volatility products in order to gain exposure to its applicable underlying commodity futures index, commodity, currency exchange rate or equity volatility index. Financial Instruments also are used to produce economically “inverse,” “inverse leveraged” or “leveraged” investment results for the Geared Funds.
