* The total percentage of leverage constitutes 22.80% through the use of tender option bonds, 17.23% in issued and outstanding VRDPs and 0.84% in investment operations, which may include the use of certain portfolio management techniques such as credit default swaps, 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.

The foregoing portfolio characteristics are as of the date indicated and can be expected to change. The Fund is a closed-end U.S.-registered management investment company advised by AllianceBernstein L. P.
