PORTFOLIO AND INVESTMENT ACTIVITY

As of November 30, 2010, the Company had long-term investments of $276.3 million. The Company’s long-term investments consisted of 43 portfolio companies, of which approximately 50% were private MLPs, 32% were public MLPs and 18% were energy debt securities.

NET ASSET VALUE

As of November 30, 2010, the Company’s net asset value was $211.0 million or $20.56 per share. This represents an increase of $1.42 per share or 7.4% for the quarter and an increase of $3.98 per share or 24.0% for the year. Presently, the fair value of the Company's investments exceeds the total cost basis reflected on the Statement of Assets and Liabilities as shown below. This difference, combined with capital and net operating losses, results in a deferred tax liability of $10.6 million, or approximately $1.03 per share.

LIQUIDITY AND CAPITAL RESOURCES

As of November 30, 2010, the Company had approximately $2.1 million in short-term investments, which consisted of money market funds and repurchase agreements. The Company’s repurchase agreements are collateralized by U.S. Treasury securities, and the Company’s counterparty is J.P. Morgan Securities Inc.

As of November 30, 2010, the Company had $57.0 million of borrowings under its credit facility (at an interest rate of 2.26%), which represented 66.4% of its borrowing base of $85.8 million (76.7% of its borrowing base attributable to quoted securities). The maximum amount that the Company can borrow under its credit facility is limited to the lesser of the commitment amount of $70.0 million or its borrowing base. As of January 27, 2011, the Company had $61.0 million of borrowings (at an interest rate of 2.27%), which represented 71.5% of the borrowing base of $85.3 million (81.2% of its borrowing base attributable to quoted securities).

DISTRIBUTION

On February 4, 2011, the Company will pay a distribution of $0.30 per share for the quarter ended November 30, 2010 to stockholders of record on January 31, 2011.

GUIDANCE

Based on the Company’s portfolio investments and average yields on those investments as of November 30, 2010, the Company estimates dividends, distributions, and interest income will be approximately $5.3 million per quarter. Such estimate does not reflect any changes in cash distributions made by MLPs or changes in interest rates based on the movement in LIBOR rates since November 30, 2010. The estimate includes $1.4 million per quarter of paid-in-kind dividends from Direct Fuels. We also expect that a portion of the $0.7 million quarterly distribution from VantaCore Partners LP ("VantaCore”) will be in the form of a paid-in-kind dividend.

(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, 2010. Amount invested and average yields for Private MLPs are based on November 30, 2010 valuations and distribution rates.

(3) The average yield includes amortization of the purchase price discounts. The amount invested and average yield excludes the Company’s ProPetro investment (the Company does not anticipate receiving cash interest payments on this investment).

Management Fees and Other Operating Expenses – Management fees are estimated to be approximately $1.2 million per quarter. Other operating expenses are estimated to be approximately $0.45 million per quarter.

Interest Expense – Based on $57.0 million borrowed under the Company’s senior secured revolving credit facility as of November 30, 2010, interest expense is estimated to be approximately $0.35 million per quarter assuming a LIBOR rate of 0.26% and a spread of 2.00%.

Based on the foregoing assumptions, the Company is expected to generate net distributable income per share of $0.32 per quarter. Included in this estimate are paid-in-kind dividends from Direct Fuels and VantaCore. The Company currently does not expect Direct Fuels to pay a cash distribution until the third quarter 2011 and then only upon achieving certain performance tests. In addition, the Company expects that VantaCore will pay a portion of its distribution in units in lieu of cash distributions during 2011.
