Neither futures trading nor swaps trading are suitable for all investors, and each involves the risk of loss. Swaps trading should only be undertaken
by investors who are Eligible Contract Participants (ECPs) within the meaning of Section 1a(18) of the Commodity Exchange Act. Futures and
swaps each are leveraged investments and, because only a percentage of a contract's value is required to trade, it is possible to lose more than the
amount of money deposited for either a futures or swaps position. Therefore, traders should only use funds that they can afford to lose without
affecting their lifestyles and only a portion of those funds should be devoted to any one trade because traders cannot expect to profit on every trade.
All references to options refer to options on futures.
