. Most
futures contracts, particularly futures contracts requiring physical delivery, are not held until the settlement date, but instead are
offset before the settlement date through the establishment of an opposite and equal futures position (buying a contract that had been
sold, or selling a contract that had been purchased). All futures transactions (except currency forward contracts) are effected through
a clearinghouse associated with the exchange on which the futures are traded.

The buyer and seller of a futures contract
are not required to deliver or pay for the underlying commodity unless the contract is held until the settlement date. However, both
the buyer and seller are required to deposit “initial margin” with a futures commodities merchant when the futures contract
is entered into. Initial margin deposits are typically calculated as a percentage of the contract’s market value. If the value
of either party’s position declines, the party will be required to make additional “variation margin” payments to settle
the change in value on a daily basis. The process is known as “marking-to-market.” Upon the closing of a futures position
through the establishment of an offsetting position, a final determination of variation margin will be made and additional cash will
be paid by or released to the Fund.

Currency Forward Contracts and Currency Futures. A foreign currency forward contract is a negotiated agreement between two parties to exchange specified amounts of two or
more currencies at a specified future time at a specified rate. The rate specified by the forward contract can be higher or lower than
the spot rate between the currencies that are the subject of the contract. Settlement of a foreign currency forward contract for the
purchase of most currencies typically must occur at a bank based in the issuing nation. Currency futures are similar to currency forward
contracts, except that they are traded on an exchange and standardized as to contract size and delivery date. Most currency futures call
for payment or delivery in U.S. dollars. Unanticipated changes in currency prices may result in losses to the Fund and poorer overall
performance for the Fund than if it had not entered into forward contracts.

Options on Futures Contracts. Options
on futures contracts are similar to options on securities except that options on futures contracts give the purchasers the right, in
return for the premium paid, to assume a position in a futures contract (a long position in the case of a call option and a short position
in the case of a put option) at a specified exercise price at any time prior to the expiration of the option
