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.

For these purposes a day is measured from the time of one net asset value (“NAV”) calculation to the next. The Fund generally seeks to remain fully invested at all times in financial instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. The Fund seeks to rebalance its portfolio each day so that its exposure to SKHY is consistent with the Daily Target. SKHY’s movements during the day will affect whether the Fund’s portfolio needs to be rebalanced. For example, if SKHY has risen on a given day, net assets of the Fund should rise (assuming there were no Creation Unit redemptions). As a result, the Fund’s exposure will need to be increased. Conversely, if SKHY has fallen on a given day, net assets of the Fund should fall (assuming there were no Creation Units issued). As a result, the Fund’s exposure will need to be decreased.Please see “Investment Objectives, Principal Investment Strategies and Related Risks” in the Fund’s Prospectus for additional details.
