The Company had $67.4 million invested in short-term repurchase agreements as of May 31, 2007.

RECENT EVENTS

On June 12, 2007, the Company made a $30.0 million equity investment in International Resource Partners LP, a private limited partnership that owns coal reserves and related assets located in Central Appalachia.

On June 11, 2007, the Company made a $50.0 million equity investment in Direct Fuels Partners, L.P. a private limited partnership that owns specialty refining, storage and distribution assets based in North Texas. The refining assets are dedicated to refining transportation mixture, or transmix, into gasoline and diesel.

On June 6, 2007, the Company announced that it established two new credit facilities, each with a three-year term, totaling $200 million. The first facility, the Senior Secured Revolving Credit Facility, has initial availability of $100 million with the ability to increase availability to $250 million. The second facility, the Treasury Secured Revolving Credit Facility, permits the Company to borrow up to $100 million and invest the proceeds in U.S. government securities. The Treasury Facility provides flexibility in the size of the Company's investments.

As of May 31, 2007, including adjustments for the investments in Direct Fuels and International Resource Partners, the Company had invested approximately $74.6 million in publicly traded MLPs and MLP affiliates, $129.4 million in private MLPs, $63.0 million in fixed income securities, and $9.4 million in repurchase agreements, with average yields (including return of capital) of 5.3%, 8.6%, 12.3% and 5.1%, respectively.

NET ASSET VALUE

On September 21, 2006, the Company completed its initial public offering of 10,000,000 shares of common stock at $25.00 per share, less an underwriting discount of $1.59 per share. After underwriting discounts, offering costs and organizational expenses, the Company's net asset value was $23.32 per share.

As of May 31, 2007, the Company's NAV had increased by 9.4% from its initial NAV to $25.52 per share. Since the Company's initial public offering, the increase in Net Asset Value is due, in large part, to the increase in value of its portfolio of MLP equity securities.
