ProShares Trust II

Initial margin is the minimum dollar amount that a counterparty to a derivatives contract that is cleared on an exchange must deposit withits commodity broker in order to establish an open position. Variation margin is the amount (generally less than initial margin) to which a Fund’s account may decline before the Fund must deliver additional margin so as to maintain open positions. A margin deposit is like a cash performance bond. It helps assure each Fund’s performance of the futures contracts that it purchases or sells. The minimum amount of margin required in connection with a particular futures contract is set by the clearinghouse that clears the futures contract and is subject to change at anytime during the term of the contract. Futures contracts are customarily bought and sold on margins that typically represent a small percentage ofthe aggregate purchase or sales price of the contract.

Brokerage firms may require higher amounts of margin than exchange minimums. These requirements may change without warning.

Margin requirements are computed at least each day by an FCM and the relevant clearinghouse. At the close of each trading day, each open futures contract is marked-to-market, that is, the gain or loss on the position is calculated from the prior day’s close. When the market value of a particular open futures contract position changes to a point where the margin on deposit does not satisfy maintenance margin requirements, a margin call is made by the FCM. If the margin call is not met within a reasonable time, the FCM may close out thecustomer’s position.
