* The total percentage of leverage constitutes 23.05% through the use of tender option bonds, 17.38% in issued and outstanding VRDPs and 0.00% in investment operations, which may include the use of certain portfolio management techniques such as credit defaultswaps, dollar rolls, negative cash, reverse repurchase agreements and when-issued securities.

** The Fund also had outstanding $100,000,000 of VRDPs at liquidation value, which is not included in Total Net Assets because it is treated as a liability for financial reporting purposes.
