 and are riskier than covered calls because there is no instrument or cover held by the Fund that can act as a partial hedge. In an “American style” option (which can generally be exercised at any time during the term of the option), the writer of an option has no control over the time when it may be required to fulfill its obligation under the option. With all options, once an option writer has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying reference instrument at the exercise price. If a put or call option purchased by the Fund is not sold when it has remaining value, and if the market price of the underlying security remains equal to or greater than the exercise price (in the case of a put), or remains less than or equal to the exercise price (in the case of a call), the Fund will lose the premium it paid for the option. Furthermore, if trading restrictions or suspensions are imposed on options markets, the Fund may be unable to close out a position.

Futures are standardized, exchange-traded contracts that obligate a purchaser to take delivery, and a seller to make delivery, of a specific amount of an asset at a specified future date at a specified price. No price is paid upon entering into a futures contract. Rather, upon purchasing or selling a futures contract the Fund is required to deposit collateral (“margin”) equal to a percentage of the contract value. Each day thereafter until the futures position is closed, the Fund will pay additional margin representing any loss experienced as a result of the futures position the prior day or be entitled to a payment representing any profit experienced as a result of the futures position the prior day. Futures involve substantial leverage risk. The sale of a futures contract limits the Fund’s risk of loss from a decline in the market value of portfolio holdings correlated with the futures contract prior to the futures contract’s expiration date. In the event the market value of the Fund holdings correlated with the futures contract increases rather than decreases, however, the Fund will realize a loss on the futures position and a lower return on the Fund holdings than would have been realized without the purchase of the futures contract.

The purchase of a futures contract may protect the Fund from having to pay more for securities as a consequence of increases in the market value for such securities during a period when the Fund was attempting to identify specific securities in which to invest in a market the Fund believes to
