Each of the Exchanges has established limitations governing the maximum number of call or put options on the same index which may be bought or written (sold) by a single investor, whether acting alone or in concert with others (regardless of whether such options are written on the same or different Exchanges or are held or written on one or more accounts or through one or more brokers). Under these limitations, option positions of all investment companies advised by the same investment adviser are combined for purposes of these limits. Pursuant to these limitations, an Exchange may order the liquidation of positions and may impose other sanctions or restrictions. These position limits may restrict the number of listed options which a Fund may buy or sell; however, the Advisor intends to comply with all limitations.
Shareholders that are U.S. persons and own, directly or indirectly, more than 50% of a Fund could be required to report annually their “financial interest” in the Fund’s “foreign financial accounts,” if any, on FinCEN Form 114, Report of Foreign Bank and Financial Accounts (“FBAR”). Shareholders should consult a tax advisor, and persons investing in a Fund through an intermediary should contact their intermediary, regarding the applicability to them of this reporting requirement.

Distributions by a Fund to a shareholder that is not a “United States person” within the meaning of the Code (such a shareholder, a “foreign shareholder”) properly reported by the Fund as (1) Capital Gain Dividends, (2) short-term capital gain dividends, and (3) interest-related dividends, each as defined and subject to certain conditions described below, generally are not subject to withholding of U.S. federal income tax.

As a general matter, the Short ProShares Funds, the CDS Short North American HY Credit ETF and the Short Bitcoin Futures Strategy ETF respond differently in response to market conditions than the Matching ProShares Funds, the Ultra ProShares Funds, the Managed Futures Strategy ETF or the Crude Oil Strategy ETF. The terms “favorable market conditions” and “adverse market conditions,” as used in this SAI, are Fund-specific.

CORPORATE DEBT SECURITIES. Corporate debt securities are fixed income securities issued by businesses to finance their operations, although corporate debt instruments may also include bank loans to companies. Notes, bonds, debentures and commercial paper are the most common types of corporate debt securities, with the primary difference being their maturities and secured or unsecured status. Commercial paper has the shortest term and is usually unsecured. The broad category of corporate debt securities includes debt issued by domestic or foreign companies of all kinds, including those with small-, mid- and large-capitalizations. Corporate debt may be rated investment-grade or below investment-grade and may carry variable or floating rates of interest.
Distributions of investment income are generally taxable to shareholders as ordinary income. Taxes on distributions of capital gains are determined by how long a Fund owned the investments that generated them, rather than how long a shareholder has owned his or her shares. In general, a Fund will recognize long-term capital gain or loss on investments it has owned for more than one year, and short-term capital gain or loss on investments it has owned for one year or less. Tax rules can alter a Fund’s holding period in investments and thereby affect the tax treatment of gain or loss on such investments. Distributions of net capital gain – the excess of net long-term capital gain over net short-term capital losses, in each case determined with reference to any loss carryforwards – that are properly reported by the Fund as capital gain dividends (“Capital Gain Dividends”) will be taxable to shareholders as long-term capital gains includible in net capital gain and taxable to individuals at reduced rates. Distributions of net short-term capital gain (as reduced by any net long-term capital loss for the taxable year) will be taxable to shareholders as ordinary income.
  •   Theft, loss or destruction. Transacting on a blockchain depends in part specifically on the use of cryptographic keys that are required to access a user’s account (or “wallet”). The theft, loss or destruction of these keys impairs the value of ownership claims users have over the relevant assets being represented by the ledger (whether “smart contracts,” securities, currency or other digital assets). The theft, loss or destruction of private or public keys needed to transact on a blockchain could also adversely affect a blockchain company’s business or operations if it were dependent on the ledger.

Don’t invest blindy. There are people in this world who would sell a blind person a pair of glasses if they could make money. Those same people play in the cryptocurrency markets and use every opportunity to exploit less-informed investors. They’ll tell you what to buy or claim certain coins will moon, just to increase the prices so they can exit. Due to the highly speculative nature of the cryptocurrency markets today, a good investor will always do his or her own research in order to take full responsibility for the potential investment outcome. Information coming from even the best investor is, at best, great information, but never a promise, so you can still get burned.
I have worked with the CME in the past on product development (specifically CDS futures) and from my experience, they would not have missed anything this simple.  In fact, while I am not a huge fan of the concept of Bitcoin futures, as currently implemented, I do not expect any errors in the operation of the CME or CBOE futures contract.  I am sure that regulators will be questioning them on the back of the OKEX, as they should, and I am also quite positive the exchanges here will pass with flying colors.
cooperatives) is a record holder of a Share in a Fund that recognizes “excess inclusion income,” then the Fund will be subject to a tax on that portion of its “excess inclusion income” for the taxable year that is allocable to such shareholders at the highest federal corporate income tax rate. The extent to which this IRS guidance remains applicable in light of the December 2006 legislation is unclear. To the extent permitted under the 1940 Act, each Fund may elect to specially allocate any such tax to the applicable CRT, or other shareholder, and thus reduce such shareholder’s distributions for the year by the amount of the tax that relates to such shareholder’s interest in the Fund. The Funds have not yet determined whether such an election will be made.
As for why you should buy a put option instead of the asset itself, the answer is simple. By buying the asset itself, you can never profit from falling prices. With put options you can, simply because their value rises as the price of the underlying stock is falling. In addition to this feature, they offer the same kind of potential for leverage that calls options do, as described above. The price of put options is calculated in a similar manner, but with the important difference being that the intrinsic value is calculated as a predetermined price of the option minus the current market price of the asset – not the other way round as is the case for call options.
