Commodity Swaps. Commodity swaps are used either as substitutes for owning a specific physical commodities or as a means of obtaining non-leveraged exposure in markets where a specific commodity is not available. Commodity swaps provide the Fund with the additional flexibility of gaining exposure to commodities by using the most cost-effective vehicle available.
On October 27, 2017, The New York Times published an article discussing the Centra ICO and its use of celebrity endorsements. For this article, the reporters reached out to Defendant Sharma to discuss his and Defendant Trapani’s perjury indictments on October 5, 2017 stemming from Defendant Trapani’s testimony that Defendant Sharma had only one alcoholic beverage the night he was arrested for driving while under the influence. In response to questions on this topic, Defendant Sharma stated, “I’m obviously not comfortable with that situation,” and added “[b]ut it’s not that I did something so intensely crazy that investors need to worry.” (emphasis added). Thus, Defendant Sharma clearly viewed persons who purchased Centra Tokens in the Centra ICO as “investors.”
general obligations of the issuer and are typically guaranteed by such issuer. Despite this guarantee, such debt securities are subject to default, restructuring or changes to the terms of the debt to the detriment of security holders. Such an event impacting a security held by a Fund would likely have an adverse impact on the Fund’s returns. Also, due to demand from other investors, certain types of these debt securities may be less accessible to the capital markets and may be difficult for a Fund to source. This may cause a Fund, at times, to pay a premium to obtain such securities for its own portfolio. For more information related to foreign sovereign, sub-sovereign and supranational securities, see “Foreign Securities” and “Exposure to Securities or Issuers in Specific Foreign Countries or Regions” above.
Disclaimer: Trading carries a high level of risk, and may not be suitable for all investors. Before deciding to invest you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with foreign exchange trading, and seek advice from an independent financial advisor if you have any doubts.
Floating and variable rate notes generally are unsecured obligations issued by financial institutions and other entities. They typically have a stated maturity of more than one year and an interest rate that changes either at specific intervals or whenever a benchmark rate changes. The effective maturity of each floating or variable rate note in a Fund’s portfolio will be based on these periodic adjustments. The interest rate adjustments are designed to help stabilize the note’s price. While this feature helps protect against a decline in the note’s market price when interest rates rise, it lowers a Fund’s income when interest rates fall. Of course, a Fund’s income from its floating and variable rate investments also may increase if interest rates rise.
Furthermore, each Fund, except the Matching ProShares Funds, the Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the CDS Short North American HY Credit ETF, the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, the Bitcoin Futures/Equity Strategy ETF has an investment objective to match the performance, a multiple (2x or 3x), the inverse (-1x) or a multiple of the inverse (-2x or -3x) of the performance of a benchmark on a single day. A “single day” is measured from the time the Fund calculates its NAV to the time of the Fund’s next NAV calculation. These Funds are subject to the correlation risks described above. In addition, while a close correlation of any Fund to its benchmark may be achieved on any single day, over time, the cumulative percentage increase or decrease in the NAV of the shares of a Fund may diverge, in some cases significantly, from the cumulative percentage decrease or increase in the benchmark due to a compounding effect as further described in the Prospectus and below.
Coinbase is not alone in making moves toward becoming an ATS. Recently, mobile payment app company Circle acquired Poloniex, another U.S.-based exchange, with plans to “clean up” the exchange. A slide that was initially leaked from a Circle presentation stated, “Circle has briefed the SEC on the transaction and indicated that upon closing that we will begin the process of registering the new entity with the SEC and FINRA as a Broker/Dealer and in turn as a licensed ATS…”
Caspian offers an institutional-grade system that allows traders to avoid this barrier and seamlessly connect to multiple exchanges. Right now, Caspian connects to 15 major crypto-exchanges, including BitMEX, Gemini (FIX), GDAX (FIX), Bitfinex, Poloniex, BitFlyer and Binance. Caspian plans to add up to 40 additional trading platforms by Q3 of this year.
•	 	Futures Position Limit Risk — Limits on the amount of futures any one entity can hold may negatively impact the Fund’s ability to meet its investment objective if such limits are reached and exceptions to such limits are not granted. Currently the position limits for bitcoin futures contracts are much lower than they are for most other futures contracts.

Cryptocurrency is also used in controversial settings in the form of online black markets, such as Silk Road. The original Silk Road was shut down in October 2013 and there have been two more versions in use since then. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.[84]
Bitcoin isn’t just an unknown commodity: it will always be an unknown commodity. Bitcoin doesn’t have the fundamentals that investors typically use to analyze an asset. Most stocks or bonds can be analyzed based on some trait of the instrument. Stocks have P/E ratios and dividends, for example, while bonds have return percentages. Bitcoin has no fundamentals that can be easily measured.

 	•	 	A new competing digital asset may pose a challenge to bitcoin’s current market dominance, resulting in a reduction in demand for bitcoin, which could have a negative impact on the price of bitcoin. It is possible that other digital currencies and trading systems could become more widely accepted and used than bitcoin. The rise of such currencies could lead to a reduction in demand for bitcoin, which could have a negative impact on the price of bitcoin.

​The price of the futures contract can deviate from the underlying price of bitcoin on spot markets, which can vary based on sentiment. But in the end, at expiration of the contract, the contract MUST settle at the price of spot. So you need to watch the main spot market price movements because the futures contracts will track the movements underlying (sometimes leading, sometimes lagging, sometimes simultaneously). There are three Chinese exchanges worth following: OKCoin, Houbi, and BTCC; there are two Western exchanges worth following: Bitfinex and Bitstamp. Other exchanges that are currently less important but still worth keeping an eye on are: ItBit, Coinbase, OKCoin USD, BTC-e, and Kraken (which has the largest BTC/EUR orderbook as of December 2015).

A Fund will be a personal holding company for federal income tax purposes if 50% or more of the Fund’s shares are owned, at any time during the last half of the Fund’s taxable year, directly or indirectly by five or fewer individuals. For this purpose, the term “individual” includes pension trusts, private foundations and certain other tax-exempt trusts. If a Fund becomes a personal holding company, it may be subject to a tax of 20% on all its investment income and on any net short-term gains not distributed to shareholders on or before the fifteenth day of the third month following the close of the Fund’s taxable year. In addition, the Fund’s status as a personal holding company may limit the ability of the Fund to distribute dividends with respect to a taxable year in a manner qualifying for the dividends-paid deduction subsequent to the end of the taxable year and will prevent the Fund from using tax equalization, which may result in the Fund paying a fund-level income tax. Each Fund intends to distribute all of its income and gain in timely manner such that it will not be subject to an income tax or an otherwise applicable personal holding company tax, but there can be no assurance that a Fund will be successful in doing so each year.
•   A Fund’s income from or the proceeds of dispositions of its non-U.S. investments may be subject to withholding and other taxes imposed by foreign countries, which will reduce the Fund’s return on and taxable distributions in respect of its non-U.S. investments. Tax conventions between certain countries and the United States may reduce or eliminate these taxes. If more than 50% of the value of a Fund’s total assets at the close of a taxable year consists of securities of foreign corporations, the Fund will be eligible to elect to “pass through” to you foreign income taxes that it has paid. If this election is made, you will be required to include your share of those taxes in gross income as a distribution from the Fund and you generally will be allowed to claim a credit (or a deduction, if you itemize deductions) for these amounts on your federal U.S. income tax return, subject to certain limitations.
The following individuals have responsibility for the day-to-day management of each Fund as set forth in the Summary Prospectus relating to such Fund. The Portfolio Managers’ business experience for the past five years is listed below. The SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership of securities in each Fund.
The Board has appointed a chief compliance officer (“CCO”) for the Trust (who is also the Chief Compliance Officer for the Advisor). The CCO reports directly to the Board and participates in the Board’s meetings. The Independent Trustees meet at least annually in executive session with the CCO, and the Funds’ CCO prepares and presents an annual written compliance report to the Board. The CCO also provides updates to the Board on the operation of the Trust’s compliance policies and procedures and on how these procedures are designed to mitigate risk. Finally, the CCO and/or other officers or employees of the Advisor report to the Board in the event that any material risk issues arise.
The Code generally imposes a 3.8% Medicare contribution tax on the net investment income of certain individuals, trusts, and estates to the extent their income exceeds certain threshold amounts. For these purposes, “net investment income” generally includes, among other things, (i) distributions paid by a Fund of ordinary dividends and capital gain dividends as described above, and (ii) any net gain from the sale, redemption or exchange of Fund shares. Shareholders are advised to consult their tax advisors regarding the possible implications of this additional tax on their investment in a Fund.

  •   The bitcoin exchanges on which bitcoin trades are relatively new and, in most cases, largely unregulated and, therefore, may be more exposed to fraud and security breaches than established, regulated exchanges for other products. Over the past several years, a number of Bitcoin Exchanges have been closed due to fraud, failure, security breaches or governmental regulations. The nature of the assets held at Bitcoin Exchanges make them appealing targets for hackers and a number of Bitcoin Exchanges have been victims of cybercrimes. No Bitcoin Exchange is immune from these risks. Fraudulent activity can increase volatility and have an adverse effect on the price of bitcoin, the general acceptance of bitcoin as an investment or means of currency and could have a negative impact on the bitcoin futures contracts in which the Fund invests and the value of the Fund.
To the extent that an Underlying RIC realizes net losses on its investments for a given taxable year, a Fund that invests in the Underlying RIC will not be able to benefit from those losses until (i) the Underlying RIC realizes gains that it can reduce by those losses, or (ii) the Fund recognizes its share of those losses when it disposes of shares in the Underlying RIC. Moreover, when a Fund makes such a disposition, any loss it recognizes will be a capital loss. A Fund will not be able to offset any capital losses from its dispositions of shares of the Underlying RIC against its ordinary income (including distributions deriving from net short-term capital gains realized by the Underlying RIC). In addition, a portion of such capital loss may be long-term, which will first offset the Fund’s capital gains, increasing the likelihood that the Fund’s short-term capital gains will be distributed to shareholders as ordinary income.
ensure the delivery of the requisite number of Fund Shares through DTC to the Custodian by no later than 10:00 a.m. Eastern Time of the second Business Day (T+2) immediately following the transmittal date. Authorized Participants should be aware that the deadline for such transfers of Fund Shares through the DTC system may be significantly earlier than the close of business on the primary listing exchange. Those making redemption requests should ascertain the deadline applicable to transfers of Fund Shares through the DTC system by contacting the operations department of the broker or depositary institution affecting the transfer of Fund Shares. The Balancing Amount, if any, must be transferred in U.S. dollars directly to the Custodian through the Federal Reserve Bank wire transfer system in a timely manner so as to be received by the Custodian no later than 2:00 p.m. Eastern Time on the second Business Day (T+2) immediately following the transmittal date. If the Custodian does not receive both the required Fund Shares and the Balancing Amount, if any, by 10:00 a.m. and 2:00 p.m., respectively, on the second Business Day (T+2) immediately following the transmittal date, such order will be deemed not in proper form and cancelled.
As of September 16, 2017, the Trustees and officers of the Trust, as a group, owned outstanding shares that entitled them to give voting instructions with respect to less than one percent of the shares of any series of the Trust; except that Mr. Michael L. Sapir owned more than 25% of the outstanding shares of ProShares S&P 500 Ex-Financials ETF and ProShares S&P 500 Ex-Health Care ETF.

•   Valuation Risk — In certain circumstances, portfolio holdings may be valued using techniques other than market quotations. The value established for a portfolio holding may be different from what would be produced through the use of another methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio holding for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio holding is sold at a discount to its established value.
  •   A decline in the adoption of bitcoin could have a negative effect on the price of bitcoin and bitcoin-related investments. Bitcoin’s adoption has been on a generally continuous climb since bitcoin first gained mass media attention in 2013. However, there can be no guarantees this growth will continue. Further, adoption of bitcoin as a means of payment has been limited when compared with the increase in the price of bitcoin, indicating that the majority of bitcoin’s use is for investment and speculative purposes. A lack of acceptance of bitcoin as a means of payment could negatively impact the price of the bitcoin futures contracts in which the Fund invests.
It is also possible that other digital currencies, typically referred to as “alt-coins”, and trading systems could become more widely accepted and used than Bitcoin. In particular, the digital asset “ethereum” has acquired a substantial share of the cryptocurrency market in recent months, which may be in part due to perceived institutional backing and/or potentially advantageous features not incorporated into bitcoin. There are other cryptocurrencies gaining momentum as the price of the bitcoin continues to rise and investors see the cheaper cryptocurrencies as attractive alternatives. The continued rise of these alt-coins can lead to a reduction in demand for bitcoin, which could have an adverse effect on the price of bitcoin and may have an adverse impact on the performance of Bitcoin Instruments and the performance of the Funds.
The Advisor, with the assistance of ISS, maintains for a period of at least five years a record of each proxy statement received and materials that were considered when the proxy was voted during the calendar year. Information on how the Funds voted proxies relating to portfolio securities for the 12-month (or shorter) period ended June 30 is available without charge, upon request, (1) by calling the Advisor at 888-776-3637, (2) on the Trust’s website at www.ProShares.com, and (3) on the SEC’s website at http://www.sec.gov.
The CFE has determined that if the Bitcoin Network is forked and a new blockchain is created, the form of bitcoin on which CFE bitcoin futures contracts and their final settlement values will be based is the form of bitcoin in U.S. dollars traded on the Gemini Exchange. The Gemini Exchange has indicated that it will support the network that has the greatest cumulative computational difficulty for the forty-eight hour period following a given fork. If the Gemini Exchange is unable to make a conclusive determination about which network has the greatest cumulative computational difficulty after forty-eight hours, or Gemini determines in good faith that this is not a reasonable criterion upon which to make a determination, the Gemini Exchange will support the network which it deems in good faith is most likely to be supported by a greater number of users and miners. The Gemini Exchange has indicated it will consult with CFE in the event of a fork. If the Gemini Exchange were to offer trading in multiple forms of bitcoin in U.S. dollars, the CFE would designate the form of bitcoin traded on the Gemini Exchange that would serve as the basis for CFE bitcoin futures contracts and their final settlement values.

Bitcoin is a relatively new type of currency—a digital or cryptocurrency secured through cryptography, or codes that can’t be read without a key. Traditional currencies are made up of paper bills and coins. Unlike traditional currencies, the bitcoin is not issued by any central government. Rather, a computer algorithm determines how many bitcoins are produced and added to the economy. This is much different than a traditional currency, where central banks typically determine how much money to print.

For Caspian, creating a crypto trading system that meets the needs of institutional investors is a benefit not only to those traders, but to the entire crypto ecosystem. Providing the infrastructure that institutions need to confidently enter the crypto world sets the stage for a much larger market. This brings needed volume, scale, stability and liquidity — not to mention the kind of credibility that can encourage even more players. In the end, we believe that building an effective trading solution will raise all boats to help crypto live up to its vast potential.
But… it's also possible that the institutional investors that are negative on bitcoin's prospects (and there's no shortage of those) may use the futures markets to put money behind their conviction. It's much easier to sell a futures contract with a lower-than-market price than it is to actually short bitcoin. These investors may well send signals to the actual bitcoin market that sends prices tumbling.
 	5.	Borrow money, except that the Fund (i) may borrow from banks (as defined in the 1940 Act) in amounts up to 331/3% of its total assets (including the amount borrowed), (ii) may, to the extent permitted by applicable law, borrow up to an additional 5% of its total assets for temporary purposes, (iii) may obtain such short-term credit as may be necessary for the clearance of purchases and sales of portfolio securities, (iv) may purchase securities on margin to the extent permitted by applicable law and (v) may enter into reverse repurchase agreements. The Fund may not pledge its assets other than to secure such borrowings or, to the extent permitted by the Fund’s investment policies as set forth in the Prospectus and SAI, as they may be amended from time to time, in connection with hedging transactions, short sales, when-issued and forward commitment transactions and similar investment strategies.

Although currently bitcoin is not regulated or is lightly regulated in most countries, including the United States, some countries have and one or more countries may in the future take regulatory actions that severely restrict the right to acquire, own, hold, sell or use bitcoin or to exchange bitcoin for fiat currency. Such restrictions could have an adverse effect on the price of bitcoin and the Bitcoin Instruments in which the Funds invest and may adversely affect an investment in the Funds.
•   Active Management Risk — The performance of actively managed funds reflects, in part, the ability of ProShare Advisors to select investments and make investment decisions that are suited to achieving the Fund’s investment objective. ProShare Advisors’ judgments about the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by ProShare Advisors fail to produce the intended results, the Fund may not achieve its investment objective and could underperform other funds with a similar investment objective and/or strategies. The Fund does not seek to provide investment performance that would be opposite of a 30% investment in bitcoin futures contracts and a 70% investment in U.S. government securities.
On October 31, 2017, CME Group, the world's leading and most diverse derivatives marketplace, had announced its intent to launch bitcoin futures in the fourth quarter of 2017. “CME Group's Bitcoin futures will be available for trading on the CME Globex electronic trading platform, and for submission for clearing via CME ClearPort, effective on Sunday, December 17, 2017 for a trade date of December 18” as per CME’s officials statement.
  •   Intellectual property claims. A proliferation of recent startups attempting to apply blockchain technology in different contexts means the possibility of conflicting intellectual property claims could be a risk to an issuer, its operations or its business. This could also pose a risk to blockchain platforms that permit transactions in digital securities.
impede the functionality of the Bitcoin Network and adversely affect the price of bitcoin. Any technical disruptions or regulatory limitations that affect Internet access may have an adverse effect on the Bitcoin Network, the price of bitcoin and the bitcoin futures contracts in which the Fund invests. In addition to technical disruptions such as cyber-attacks, the potential elimination of the net neutrality regulations in the U.S. may have a negative impact on bitcoin and the Bitcoin ecosystem.
The proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and there's currently no standard form of it. Some cryptocurrencies use a combined proof-of-work/proof-of-stake scheme.[18]
Creation Units of Shares may be purchased only by or through a DTC Participant that has entered into an Authorized Participant Agreement with the Distributor. Such Authorized Participant will agree pursuant to the terms of such Authorized Participant Agreement on behalf of itself or any investor on whose behalf it will act, as the case may be, to certain conditions, including that such Authorized Participant will make available an amount of cash sufficient to pay the Balancing Amount, defined below, and the Transaction Fee, described below in “Transaction Fees”. The Authorized Participant may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Balancing Amount. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement, and that therefore orders to purchase Creation Units may have to be placed by the investor’s broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants.

The identity and number of shares of the Deposit Securities required for a Portfolio Deposit for each Fund changes as rebalancing adjustments and corporate action events are reflected from time to time by ProShare Advisors with a view to the investment objective of the applicable Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the securities constituting the relevant securities index, as applicable. The adjustments described above will reflect changes, known to ProShare Advisors on the date of announcement to be in effect by the time of delivery of the Portfolio Deposit, in the composition of the subject index being tracked by the relevant Fund, as applicable, or resulting from stock splits and other corporate actions. In addition, the Trust reserves the right to permit or require the substitution of an amount of cash (i.e., a “cash in lieu” amount) to be added to the Balancing Amount to replace any Deposit Security which may not be available in sufficient quantity for delivery or for other similar reasons. A Transaction Fee may be assessed on any “cash in lieu” amounts, as further described below under “Transaction Fees”. For the High Yield—Interest Rate Hedged, the Investment Grade—Interest Rate Hedged and the Short Term USD Emerging Markets Bond ETF, a minimum of 70% of the Deposit Securities must be delivered, unless such purchase is made on a cash-only basis.


•   Tax Risk — In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategies will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund can make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its

The Fund can make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.
As bitcoin and other digital assets have grown in popularity and in market size, certain U.S. federal and state governments, foreign governments and self-regulatory agencies have begun to examine the operations of bitcoin, digital assets, the Bitcoin Network, bitcoin users, Bitcoin Exchanges and the Bitcoin Exchange Market. These regulatory efforts include, but are not limited to, the following.
Making money arbitraging bitcoin futures can be extremely simple. Futures contracts typically trade at a premium, and all you have to do, starting with USD, is buy bitcoin at Spot price and sell futures of the same amount at premium price. Then just wait until expiration to make your arb profit in bitcoin (which you can then put in USD). Whether it's a weekly, monthly, quarterly, or any futures contract, as long as it's in a premium, you lock in the sale price and earn the arbitrage profit.
