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.

Now, if that margin-call does not get filled and the price continues to fall, then I'm making profits on my contract but nobody is paying for it since the counterparty who got margin-called didn't get the liquidation order filled. So what happens is that at settlement time of the contract, that unfilled liquidation loss to the system will be deducted from the profits of ALL traders before they are distributed.
 	•	 	Swap Agreements are agreements 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 return (or differentials in rates of return) earned or realized on particular predetermined investments or instruments.

Changes in the Bitcoin Network could have an adverse effect on the operation and value of bitcoin, which could have an adverse effect on the value of Bitcoin Futures Contracts and the value of Fund Shares. The open source nature of the Bitcoin protocol permits any developer to review the underlying code and suggest changes to it via “Bitcoin Improvement Proposals”, or “BIPs.” If accepted by a sufficient number of miners, BIPs may result in substantial changes to the Bitcoin Network, including changes that result in “forks.” Such changes may influence
The Index Receipt Agent makes available through the NSCC on each Business Day, either immediately prior to the opening of business on the Exchange or the night before, the list of the names and the required number of shares of each Deposit Security to be included in the current Portfolio Deposit (based on information at the end of the previous Business Day) for each applicable Fund. Such Portfolio Deposit is applicable, subject to any adjustments as described below, in order to effect purchases of Creation Units of Shares of such Fund until the next-announced Portfolio Deposit composition is made available.

​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).
For each intervening holiday in the applicable foreign market that is not a holiday observed by the U.S. equity markets, the redemption settlement cycle will be extended by the number of days of such intervening holiday. In addition to holidays, other unforeseeable closings in a foreign market, including due to regulatory action, may also prevent a Fund from delivering securities within the normal settlement period.

•   Any distributions from income or short-term capital gains that you receive generally are taxable to you as ordinary dividends for federal income tax purposes. Ordinary dividends you receive that a Fund reports as “qualified dividend income” may be taxed at the same rates as long-term capital gains, but will not be considered long-term capital gains for other federal income tax purposes, including the calculation of net capital losses.
Investments by a Fund in a wholly-owned foreign subsidiary, debt obligations issued or purchased at a discount and certain derivative instruments could cause the Fund to recognize taxable income in excess of the cash generated by such investments, potentially requiring the Fund to dispose of investments (including when otherwise disadvantageous to do so) in order to meet
During the fiscal year ended May 31, 2017, the Advisor recouped $161,605 from UltraPro S&P 500 Fund pursuant to an Investment Advisory Agreement and the Expense Limitation Agreement between the Advisor and the Trust, on behalf of the Fund. During the fiscal year ended May 31, 2016, the Advisor recouped $155,882 from the UltraPro S&P 500 Fund pursuant to an Investment Advisory Agreement and the Expense Limitation Agreement between the Advisor and the Trust, on behalf of the Fund. During the fiscal year ended May 31, 2015, the Advisor recouped $259,539 from the UltraPro S&P 500 Fund pursuant to an Investment Advisory Agreement and the Expense Limitation Agreement between the Advisor and the Trust, on behalf of the Fund.
The NAV of each Fund is typically determined each business day at 3:00 p.m., Eastern Time on days when                    is open for trading. The [            ] Exchange is open every week, Monday through Friday, except when the following holidays are celebrated: New Year’s Day, Martin Luther King, Jr. Day (the third Monday in January), Presidents’ Day (the third Monday in February), Good Friday, Memorial Day (the last Monday in May), Independence Day, Labor Day (the first Monday in September), Thanksgiving Day (the fourth Thursday in November) and Christmas Day. An Exchange may close early on the business day before each of these holidays and on the day after Thanksgiving Day. Exchange holiday schedules are subject to change without notice. If the exchange or market on which a Fund’s investments are primarily traded closes early, the NAV may be calculated prior to its normal calculation time. Creation/ redemption transaction order time cutoffs would also be accelerated.

Slippage is when the actual price we execute at is different from what we expect. In this case, a perfect market would let us sell the bitcoin and settle the future at precisely the same time and price. But in practice, market imperfections and Bitcoin volatility could lead to the price moving between the two trades, wiping out profits or putting you in the red.

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.
Each Fund’s portfolio turnover rate, to a great extent, will depend on the purchase, redemption and exchange activity of the Fund’s investors. A Fund’s portfolio turnover may vary from year to year, as well as within a year. The nature of the Funds may cause the Funds to experience substantial differences in brokerage commissions from year to year. The overall reasonableness of brokerage commissions is evaluated by the Advisor based upon its knowledge of available information as to the general level of commissions paid by other institutional investors for comparable services. High portfolio turnover and correspondingly greater brokerage commissions depend, to a great extent, on the purchase, redemption, and exchange activity of a Fund’s investors, as well as each Fund’s investment objective and strategies. Consequently, it is difficult to estimate what each Fund’s actual portfolio turnover rate will be in the future. However, it is expected that the portfolio turnover experienced by the Funds from year to year, as well as within a year, may be substantial. A higher portfolio turnover rate would likely involve correspondingly greater brokerage commissions and transaction and other expenses that would be borne by the Funds. The nature of the Funds may cause the Funds to experience substantial differences in brokerage commissions from year to year. The overall reasonableness of brokerage commissions is evaluated by the Advisor based upon its knowledge of available information as to the general level of commissions paid by other institutional investors for comparable services. In addition, a Fund’s portfolio turnover level may adversely affect the ability of the Fund to achieve its investment objective. “Portfolio Turnover Rate” is defined under the rules of the SEC as the value of the securities purchased or securities sold, excluding all securities whose maturities at time of acquisition were one year or less, divided by the average monthly value of such securities owned during the year. Based on this definition, instruments with remaining maturities of less than one year, including swap agreements, options and futures contracts in which the Funds invest, are excluded from the calculation of Portfolio Turnover Rate for each Fund. For those Funds that commenced operations prior to May 31, 2017, each such Fund’s turnover rate information is set forth in the annual report to shareholders. Portfolio turnover rates are also shown in each Fund’s summary prospectus.

The Funds may enter into forward contracts to attempt to gain exposure to an index or asset without actually purchasing such asset, or to hedge a position. Forward contracts are two-party contracts pursuant to which one party agrees to pay the counterparty a fixed price for an agreed-upon amount of an underlying asset or the cash value of the underlying asset at an agreed-upon date. When required by law, a Fund will segregate liquid assets in an amount equal to the value of the Fund’s total assets committed to the consummation of such forward contracts. Obligations under forward contracts so covered will not be considered senior securities for purposes of a Fund’s investment restriction concerning senior securities. Forward contracts that cannot be terminated in the ordinary course of business within seven days at approximately the amount at which a Fund has valued the asset may be considered to be illiquid for purposes of the Fund’s illiquid investment limitations. A Fund will not enter into a forward contract unless the Advisor believes that the other party to the transaction is creditworthy. The counterparty to any forward contract will typically be a major, global financial institution. A Fund bears the risk of loss of the amount expected to be received under a forward contract in the event of the default or bankruptcy of a counterparty. If such a default occurs, a Fund will have contractual remedies pursuant to the forward contract, but such remedies may be subject to bankruptcy and insolvency laws, which could affect the Fund’s rights as a creditor. The Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, and the Bitcoin Futures/Equity Strategy ETF may each invest in forward contracts where commodities are the underlying asset.
•   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.
When a new crypto is launched, its founders announce how many coins will be mined. Once the quota is reached, no further coins can be produced. The first digital coin introduced was Bitcoin, which remains today the benchmark for all other digital coins. Among other currencies that have made their way into the cryptocurrency hall-of-fame we have: Ethereum, Ripple, Litecoin, EOS, and a number of derived currencies, including Bitcoin Cash and Bitcoin Gold.
The term altcoin has various similar definitions. Stephanie Yang of The Wall Street Journal defined altcoins as "alternative digital currencies,"[25] while Paul Vigna, also of The Wall Street Journal, described altcoins as alternative versions of bitcoin.[26] Aaron Hankins of the MarketWatch refers to any cryptocurrencies other than bitcoin as altcoins.[27]

In addition, the Advisor, its affiliates and principals may trade for their own accounts. Consequently, non-customer and proprietary trades may be executed and cleared through any prime broker or other broker utilized by clients. It is possible that officers or employees of the Advisor may buy or sell securities or other instruments that the Advisor has recommended to, or purchased for, its clients and may engage in transactions for their own accounts in a manner that is inconsistent with the Advisor’s recommendations to a client. Personal securities transactions by employees may raise potential conflicts of interest when such persons trade in a security that is owned by, or considered for purchase or sale for, a client. The Advisor has adopted policies and procedures designed to detect and prevent such conflicts of interest and, when they do arise, to ensure that it effects transactions for clients in a manner that is consistent with its fiduciary duty to its clients and in accordance with applicable law.

U.S. government securities include U.S. Treasury securities, which are backed by the full faith and credit of the U.S. Treasury and which differ only in their interest rates, maturities, and times of issuance: U.S. Treasury bills, which have initial maturities of one year or less; U.S. Treasury notes, which have initial maturities of one to ten years; and U.S. Treasury bonds, which generally have initial maturities of greater than ten years. In addition, U.S. government securities include Treasury Inflation-Protected Securities (“TIPS”). TIPS are inflation-protected public obligations of the U.S. Treasury. These securities are designed to provide inflation protection to investors. TIPS are income generating instruments whose interest and principal payments are adjusted for inflation – a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index such as the Consumer Price Index. A fixed-coupon rate is applied to the inflation-adjusted principal so that as inflation rises, both the principal value and the interest payments increase. This can provide investors with a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of the inflation-adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds. In addition, TIPS decline in value when real interest rates rise. However, in certain interest rate environments, such as when real interest rates are rising faster than nominal interest rates, TIPS may experience greater losses than other fixed income securities with similar duration.

There's a lot of ins and outs which can get confusing in arbitrage trading. We won't go into the technicals of why futures contracts trade at a premium to spot price. You can read a full explanation here. If it's not of interest to you, all you need to know is that there's a tendency, the further out in time the futures contract expires, for the premium to spot to be higher and higher in nominal percentage terms.
