Kayne Anderson Energy Development Company Announces Results for the Fiscal Year Ended November 30, 2008

HOUSTON, TX -- (Marketwire - February 09, 2009) - February 9, 2009 - (NYSE: KED) Kayne Anderson Energy Development Company (the "Company") today announced its financial results for the fiscal year ended November 30, 2008.

HIGHLIGHTS

--  Net asset value: previously disclosed unaudited NAV of $14.87 has been
    revised to $16.10 per share
--  The Company paid its quarterly dividend of $0.35 per share
--  Net investment loss for fiscal 2008: $3.5 million
--  Net realized gain for fiscal 2008: $7.5 million
--  Net unrealized losses for fiscal 2008: $70.8 million
    

"Fiscal 2008 was a difficult year due to challenges in the financial markets and commodity markets and the onset of a global recession. While we expect that fiscal 2009 will present challenges as well, we are optimistic that our portfolio is well positioned to benefit from an upturn in the financial markets and commodity markets," stated Kevin S. McCarthy, Chairman and CEO of the Company. "In spite of the challenges we faced in 2008, we were pleased to have maintained a strong balance sheet and deliver over $1.60 per share of dividends to our shareholders over the last twelve months."

NET ASSET VALUE

As of November 30, 2008, the Company's NAV was $162.7 million or $16.10 per share. This represents an increase of $1.23 per share compared to the unaudited NAV that the Company announced on January 9, 2009. The principal reason for the increase is a positive adjustment to our valuation allowance for deferred tax assets and a change to the estimated post-closing adjustment related to the sale of Millennium Midstream Partners, L.P. ("Millennium").

In our unaudited NAV that was announced on January 9, 2009, the Company included a valuation allowance of $12.9 million or $1.27 per share on the Company's deferred tax asset. The valuation allowance was based on the amount of deferred tax assets that we estimated could be utilized within three years and our belief that this methodology was consistent with industry practice. During the audit of the Company's financial statements, we were able to demonstrate, after weighing all of the objective evidence, that it was more likely than not that the Company would be able to utilize its entire deferred tax asset prior to its expiration. This threshold is established under the Statement of Financial Accounting Standard No. 109, "Accounting for Income Taxes." As such, we were required to reverse the previously announced valuation allowance.

The Company also changed its estimated post-closing working capital adjustment related to its sale of Millennium, which reduced NAV by $0.4 million or $0.04 per share. This change in estimate is based on information that became available to Millennium in January 2009, and generally accepted accounting principles require that this type of subsequent event be reflected in the financial statements as of November 30, 2008.

PORTFOLIO AND INVESTMENT ACTIVITY

As of November 30, 2008, the Company had long-term investments of $182.3 million. The Company's long-term investments consisted of 57 portfolio companies, which were comprised of approximately 51% in private MLPs, 33% in public MLPs and 16% in fixed income securities.

Our percentage invested in public MLPs at November 30, 2008 is greater than our targeted range because such percentage includes 1.6 million unregistered common units of Eagle Rock Energy Partners, L.P., which were received as partial consideration for the sale of our interest in Millennium. Over time, the Company intends to rotate out of certain public MLPs and into additional private MLPs as attractive investment opportunities arise.

RESULTS OF OPERATIONS - QUARTER ENDED NOVEMBER 30, 2008

Investment income was $1.3 million and consisted primarily of interest income on fixed income investments and short-term investment in repurchase agreements. The Company received $4.2 million of cash dividends and distributions, of which $3.6 million was treated as a return of capital.

Net realized gains were $9.3 million, which consisted of a $16.1 million gain related to the sale of Millennium that was partially offset by net realized losses of $1.3 million and a deferred income tax expense of $5.5 million.

Net unrealized losses were $65.8 million, which consisted of $104.5 million of unrealized losses from investments net of a deferred income tax benefit of $38.7 million.

The Company's net decrease in net assets resulting from operations for the period was $57.3 million. This decrease is composed of the net unrealized losses of $65.8 million; net realized gains of $9.3 million and a net investment loss of $0.7 million as noted above.

(1) Average yields include return of capital distributions. Return of
    capital distributions are reported as a reduction to gross dividends
    and distributions to arrive at net investment income reported under
    generally accepted accounting principles.

(2) Average yields for Public MLPs and MLP Affiliates are based on the most
    recently declared distributions as of November 30, 2008.  Amount
    invested and average yields for Private MLPs are based on
    November 30, 2008 valuations and distribution rates.

(3) The amount invested and average yield excludes the Company's ProPetro
    investment (the Company does not anticipate receiving cash interest
    payments during fiscal 2009 on this investment). The average yield
    includes amortization of the purchase price discount, as reported on
    the Company's income statement.

(4) Includes repurchase agreements at November 30, 2008 less Q4 2008
    dividend/distribution of $3.5 million.

Base Management Fees and Other Operating Expenses -- Base management fees are estimated to be approximately $0.8 million per quarter. Other operating expenses are estimated to be approximately $0.6 million a quarter.

Interest Expense -- Based on $57.0 million borrowed under the Company's senior secured credit facility as of November 30, 2008, interest expense is estimated to be approximately $0.5 million per quarter assuming a LIBOR rate of 1.90%.

The Company does not provide guidance on realized gains or incentive management fees.

Payment of future dividends/distributions is subject to approval by the Company's Board of Directors, as well as meeting the covenants of the Company's revolving credit facility. Should market conditions deteriorate further and/or interest income or distributions from the Company's investments be less than expectations, the Company will determine the appropriate dividend/distribution rate at that time.

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.
