 need to liquidate investments in order to fund a redemption of some or all of the Preferred Shares. Liquidations at times of adverse economic conditions may result in a loss to the Fund. At other times, these liquidations may result in gain at the Fund level and thus in additional taxable distributions to Common Shareholders. See “Tax Matters” for more information. Any Preferred Shares, total return swaps, reverse repurchases, loans of portfolio securities, short sales and when-issued, delayed delivery and forward commitment transactions, credit default swaps, basis swaps and other swap agreements, purchases or sales of futures and forward contracts (including foreign currency exchange contracts), call and put options other derivatives by the Fund or counterparties to the Fund’s other leveraging transactions, if any, would have seniority over the Fund’s Common Shares. When the Fund issues Preferred Shares, the Fund pays (and the Common Shareholders bear) all costs and expenses relating to the issuance and ongoing maintenance of Preferred Shares. In addition, holders of Preferred Shares issued by the Fund would have complete priority over Common Shareholders in the distribution of the Fund’s assets. Furthermore, preferred shareholders, voting separately as a single class, have the right to elect two members of the Board at all times and to elect a majority of the trustees in the event two full years’ dividends on the Preferred Shares are unpaid, and also have separate class voting rights on certain matters. Accordingly, preferred shareholders may have interests that differ from those of Common Shareholders, and may at times have disproportionate influence over the Fund’s affairs. Because the fees received by the Investment Manager may increase depending on the types of leverage utilized by the Fund, the Investment Manager has a financial incentive for the Fund to use certain forms of leverage, which may create a conflict of interest between the Investment Manager, on the one hand, and the Common Shareholders, on the other hand. Derivatives Risk The Fund may, but is not required to, utilize a variety of derivative instruments (both long and short positions) for investment or risk management purposes. Derivatives are financial contracts whose value depends on, or is derived from, the value of an underlying asset, reference rate or index. For example, the Fund may use derivative instruments for purposes of increasing liquidity, providing efficient portfolio management, broadening investment opportunities (including taking short or negative positions), implementing a tax or cash management strategy, gaining exposure to a particular security or segment of the market, modifying the effective duration of the Fund’s portfolio investments and/or enhancing total return.
