 of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. Premiums paid for purchasing options that expire are treated as realized losses. Options purchased or sold by a Fund may be traded on a securities or options exchange. Such options typically have minimal exposure to counterparty risk. However, an exchange or market may at times find it necessary to impose restrictions on particular types of options transactions, such as opening transactions. If an underlying security ceases to meet qualifications imposed by an exchange or the Options Clearing Corporation, new series of options on that security will no longer be opened to replace the expiring series, and opening transactions in existing series may be prohibited. OTC options are options not traded on exchanges or backed by clearinghouses. Rather, they are entered into directly between a Fund and the counterparty to the option. In the case of an OTC option purchased by a Fund, the value of the option to the Fund will depend on the willingness and ability of the option writer to perform its obligations to the Fund. In addition, OTC options may not be transferable and there may be little or no secondary market for them, so they may be considered illiquid. It may not be possible to enter into closing transactions with respect to OTC options or otherwise to terminate such options, and as a result a Fund may be required to remain obligated on an unfavorable OTC option until its expiration.

Swap agreements are typically two-partycontracts entered into primarily by institutional investors. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or “swapped” between the parties are generally calculated with respect to a “notional amount” (i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate or in a “basket” of securities representing a particular index). In a total return swap, one party typically agrees to pay to the other a short-term interest rate in return for a payment at one or more times in the future based on the increase
