These distributions are the first declared by the Fund following its successful initial public offering that raised approximately $218.5 million in common share assets, assuming full exercise of the underwriters’ overallotment option, which may or may not occur.

The Fund’s primary investment objective is to provide current income and then to liquidate and distribute substantially all of the Fund’s net assets to stockholders on or about December 2, 2024. As a secondary investment objective, the Fund will seek capital appreciation. There can be no assurance the Fund will achieve its investment objectives.

The Fund seeks to achieve its investment objectives by investing, under normal market conditions, at least 80% of its net assets in investment grade corporate fixed income securities of varying maturities. While the Fund may invest up to 20% of its net assets in below investment grade securities, the Fund will, under normal market conditions, maintain a portfolio with an overall dollar-weighted average of investment grade credit quality.

This press release is not for tax reporting purposes but is being provided to announce the amount of the Fund’s distributions that have been declared by the Board of Directors. In early 2010, after definitive information is available, the Fund will send stockholders a Form 1099-DIV, if applicable, specifying how the distributions paid by the Fund during the prior calendar year should be characterized for purposes of reporting the distributions on a stockholder’s tax return (e.g., ordinary income, long-term capital gain or return of capital).
