HOUSTON--(BUSINESS WIRE)--February 16, 2010--(NYSE:KED) Kayne Anderson Energy Development Company (the “Company”) announced today that it has filed with the Securities and Exchange Commission its annual report containing audited financial statements for the year ended November 30, 2009.

The Company is a non-diversified, closed-end investment company that elected to be treated as a business development company under the Investment Company Act of 1940. The Company's investment objective is to generate both current income and capital appreciation primarily through equity and debt investments. The Company will seek to achieve this objective by investing at least 80% of its net assets together with the proceeds of any borrowings (its "total assets") in securities of companies that derive the majority of their revenue from activities in the energy industry, including: (a) Midstream Energy Companies, which are businesses that operate assets used to gather, transport, process, treat, terminal and store natural gas, natural gas liquids, propane, crude oil or refined petroleum products; (b) Upstream Energy Companies, which are businesses engaged in the exploration, extraction and production of natural resources, including natural gas, natural gas liquids and crude oil, from onshore and offshore geological reservoirs; and (c) Other Energy Companies, which are businesses engaged in owning, leasing, managing, producing, processing and sale of coal and coal reserves; the marine transportation of crude oil, refined petroleum products, liquefied natural gas, as well as other energy-related natural resources using tank vessels and bulk carriers; and refining, marketing and distributing refined energy products, such as motor gasoline and propane to retail customers and industrial end-users.
