This material shall not constitute an offer to sell or a solicitation to buy, nor shall there be any sale of the securities in any jurisdiction in which such offer or sale is not permitted. Past performance is not a guarantee of future results. An investment in the fund could suffer loss. Current performance may be lower or higher than that shown based on market fluctuations from the end of the reported period. Before making an investment in the fund, you should consider the investment objective, risks, charges and expenses of the fund, which, together with and other important information are included in the fund's most recent prospectus and other filings with the SEC. There can be no assurance that the fund's investment objectives will be attained. Shares of closed-end funds frequently trade at a market price that is below their net asset value. Leverage creates risks which may adversely affect return, including the likelihood of greater volatility of net asset value and market price of common shares, and fluctuations in dividend rates on any preferred shares.
