In traditional financial markets, derivatives are used as speculation objects as well as insurance against losses. The latter is known as hedging. One popular variety of derivatives used for hedging are called futures. A future is a contract between two parties in which one party agrees to pay the other a predetermined amount of money for an underlying asset at a specific point in time.
Distributions are taxable whether shareholders receive them in cash or reinvest them in additional shares. Distributions are also taxable to shareholders even if they are paid from income or gains earned by a Fund before a shareholder’s investment (and thus were included in the price the shareholder paid for the Fund shares). Investors should be careful to consider the tax implications of buying shares of a Fund just prior to a distribution. The price of shares purchased at this time will include the amount of the forthcoming distribution, but the distribution will generally be taxable.

You could imagine the spread going the other way, though. If everyone really was clamoring to short bitcoin, and if the futures offered a more convenient way to do it than the bitcoin exchanges, then you'd expect the short sellers to pay a premium to short via futures. Instead of selling a bitcoin at $18,000 today, they'd be willing to sell a synthetic bitcoin for $17,500, paying the spread to an arbitrageur who was willing to do the actual shorting for them. But the fact that the spread is mostly positive, and that bitcoin's price has been mostly going up, suggests that the demand has mostly been for synthetic long positions, not short.

Bitcoin futures contracts are a new type of futures contract that began trading in December 2017. Unlike the established futures markets for traditional physical commodities, the market for bitcoin futures contracts is in the developmental stage and has very limited volume, trading and operational history. Bitcoins and other cryptocurrencies are a new and developing asset class subject to both developmental and regulatory uncertainty. As such, bitcoin futures contracts and the market for bitcoin futures contracts may be riskier, less liquid, more volatile and more vulnerable to economic, market, industry, regulatory and other changes than more established futures contracts and futures markets. There is no assurance that a liquid market will emerge or be sustained for bitcoin futures contracts. The liquidity of the market for bitcoin futures contracts will depend on, among other things, the supply and demand for bitcoin futures contracts, the adoption of bitcoin and the commercial and speculative interest in the market for bitcoin futures contracts and the potential ability to hedge against the price of bitcoin with exchange-traded bitcoin futures contracts. Additionally, if market participants executing trades in bitcoin futures contracts face constraints, including capital constraints, security risks, or high execution costs, the price of bitcoin futures contracts may fail to capture price movements in the underlying price of bitcoin.
When the Fund has an open futures contract position, it is subject to daily variation margin calls that could be substantial in the event of adverse price movements. If the Fund has insufficient cash to meet daily variation margin requirements, it might need to sell securities at a time when such sales are disadvantageous. Futures markets are highly volatile and the use of or exposure to futures contracts may increase volatility of the Fund’s NAV. Futures contracts are also subject to liquidity risk.
At the expiration of the contract you are trading, all positions get closed out and settled. Different exchanges use different anchors to settle against. To avoid manipulation, most of them use an index. OKCoin uses a custom 6-exchange index (3 chinese, 3 Western), while BitMEX, Deribit, Coinpit, and CryptoFacilities use a multi-spot-exchange Index to settle all of its contracts at expiration. This minimizes the risk of any manipulation if contracts settled on a single exchange's price, but it also makes it more difficult to manage your hedges since there's no way to "buy" or "sell" an index. No system is perfect, and each one offers different unique pro's and con's, just like your selection of contract type and length. So depending on your case you may want something different than someone else.

D – An obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless Standard & Poor’s believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to a distressed exchange offer.


Mass adoption of bitcoin will also require an accommodating regulatory environment. A lack of expansion in usage of bitcoin and the Bitcoin Blockchain could adversely affect the market for bitcoin and may have a negative impact on the performance of the Bitcoin Instruments and the performance of the Funds. Even if growth in bitcoin adoption continues in the near or medium-term, there is no assurance that bitcoin usage, or the market for Bitcoin Instruments, will continue to grow over the long-term. A contraction in use of bitcoin may result in increased volatility or a reduction in the price of bitcoin, as well as increased volatility or a reduction in the price of Bitcoin Derivatives, which could adversely impact the value of an investment in a Fund. Conversely, a rapid expansion in the use of bitcoin may result in rapid appreciation in the price of bitcoin, which could adversely impact the value of a Fund which takes a short position in bitcoin futures contracts.
The Administrator pays all fees and expenses that are directly related to the services provided by the Administrator to the Funds; each Fund reimburses the Administrator for all fees and expenses incurred by the Administrator which are not directly related to the services the Administrator provides to the Funds under the service agreement. Each Fund may also reimburse the Administrator for such out-of-pocket expenses as incurred by the Administrator in the performance of its duties. For these services each Fund that was operational for the period indicated paid the Administrator and Citi the amounts set forth below. Because the New Fund was not operational at the end of the Trust’s last fiscal year, information on fees paid to the Administrator and Citi on behalf of the New Fund is not included in this SAI.
The fund performance for a Geared ProShares Fund can be estimated given any set of assumptions for the factors described above. The tables on the next five pages illustrate the impact of two factors, benchmark volatility and benchmark performance, on a Geared Fund. Benchmark volatility is a statistical measure of the magnitude of fluctuations in the returns of a benchmark and is calculated as the standard deviation of the natural logarithm of one plus the benchmark return (calculated daily), multiplied by the square root of the number of trading days per year (assumed to be 252). The tables show estimated Fund returns for a number of combinations of benchmark performance and benchmark volatility over a one-year period. Assumptions used in the tables include: (a) no dividends paid with respect to securities included in the underlying benchmark; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leverage or inverse exposure) of zero percent. If Fund expenses and/or actual borrowing lending rates were reflected, the Fund’s performance would be different than shown.
Yields on U.S. government securities depend on a variety of factors, including the general conditions of the money and bond markets, the size of a particular offering, and the maturity of the obligation. Debt securities with longer maturities tend to produce higher yields and are generally subject to potentially greater capital appreciation and depreciation than obligations with shorter maturities and lower yields. The market value of U.S. government securities generally varies inversely with changes in market interest rates. An increase in interest rates, therefore, would generally reduce the market value of a Fund’s portfolio investments in U.S. government securities, while a decline in interest rates would generally increase the market value of a Fund’s portfolio investments in these securities.

Credit Default Swaps (“CDS”): In the case of a CDS, the agreement will reference one or more debt securities or reference entities. The protection “buyer” in a credit default contract is generally obligated to pay the protection “seller” an upfront or a periodic stream of payments over the term of the contract until a credit event, such as a default, on a reference entity has occurred. If a credit event occurs, the seller generally must pay the buyer: a) the full notional value of the swap; or b) the difference between the notional value of the defaulted reference entity and the recovery price/rate for the defaulted reference entity. CDS are designed to reflect changes in credit quality, including events of default. The CDS Short North American HY Credit ETF will normally be a “buyer” of CDS (also referred to as a buyer of protection or a seller of risk). The CDS Short North American HY Credit ETF will primarily invest in centrally cleared, index-based CDS that provide credit exposure through a single trade to a basket of reference entities. The CDS Short North American HY Credit ETF may also invest in single-name CDS. Single-name CDS provide exposure to a single reference entity and are not centrally cleared.

More generally, investments by a Fund in options, futures, forward contracts, swaps and other derivative financial instruments are subject to numerous special and complex tax rules. These rules could affect whether gains and losses recognized by a Fund are treated as ordinary or capital, accelerate the recognition of income or gains to a Fund and defer or possibly prevent the recognition or use of certain losses by a Fund. The rules could, in turn, affect the amount, timing or character of the income distributed to shareholders by a Fund. In addition, because the tax rules applicable to such instruments may be uncertain under current law, an adverse determination or future IRS guidance with respect to these rules (which determination or guidance could be retroactive) may affect whether a Fund has made sufficient distributions and otherwise satisfied the relevant requirements to maintain its qualification as a RIC and avoid a Fund-level tax.
Taking their prices from bitcoin futures, the swaps will not handle bitcoin directly. Seeing as Morgan Stanley is a regulated and established financial institution, tying the product to futures contracts is a safer bet than basing them on bitcoin’s spot price, as the Chicago Mercantile Exchange and Chicago Board of Exchange offer fully-regulated bitcoin futures from which Morgan Stanley can pool pricing data.
There are also tax risks associated with investments in MLPs. While there are benefits to MLPs that are treated as partnerships for federal income tax purposes, a change to current tax law or in the underlying business of a given MLP could result in the MLP being treated as a corporation for federal income tax purposes. If the MLP were treated as a corporation, the MLP would be required to pay federal income tax on its taxable income, which would reduce the amount of cash available for distribution by the MLP. In addition, because MLPs generally conduct business in multiple states, the Fund may be subject to income or franchise tax in each of the states in which the partnership does business. The additional cost of preparing and filing the tax returns and paying related taxes may adversely impact the Fund’s return.
Note: This Prospectus provides general U.S. federal income tax information only. Your investment in the Fund may have other tax implications. If you are investing through a tax-deferred retirement account, such as an individual retirement account (IRA), special tax rules apply. Please consult your tax advisor for detailed information about a Fund’s tax consequences for you. See “Taxation” in the SAI for more information.
Well since then bitcoin is up more than 50 percent; it reached a record of $19,511 early Monday, hours after CME launched its futures contract. "Bitcoin Climbs as Futures Debut Fails to Incite Attack by Shorts," is the Bloomberg headline about Sunday's start of trading on CME. On the other hand, bitcoin was actually down a bit on the first full day of CME trading yesterday, and fell further overnight; "Bitcoin Futures Prices Fall in CME Debut" is the Wall Street Journal headline about Monday's trading. It is of course still very early days for the futures, and it's still possible that the shorts will come in and drive the price down. I guess it's even possible bitcoin bulls and bears will both flock to the futures market and trade with each other to find an efficient and stable price that reflects bitcoin's fundamental value, whatever that is.
Since you bought 68.4246 BTC, you want to short 68 BTC and lock in the USD value. You will have 0.4246 BTC left over, which will give you a slightly long bias. You can either fix this by only buying 68 BTC in step 1 or by giving yourself more short exposure by shorting 69 BTC. Remember that CryptoFacilities contracts are inverse (which allow locking in USD) and are denominated in BTC
