Unfulfilled Demand for Structured Debt Financing to Technology-Related Companies.

Private debt capital in the form of structured debt financing from specialty finance companies continues to be an important source of funding for technology-related companies. We believe that the level of demand for structured debt financing is a function of the level of annual venture equity investment activity. During 2011, venture capitalbacked companies received, in approximately 3,209 transactions, equity financing in an aggregate amount of approximately $32.6 billion, representing a 10.1% increase from the same period of the preceding year, as reported by Dow Jones VentureSource. In addition, overall, the median round size during the three-month periods ended December 31, 2011 and 2010 was approximately $4.0million and $4.1million, respectively. We believe the larger number of venture-backed companies receiving financing provides us a greater opportunity to provide debt financing to these companies. Overall, seed- and first-round deals made up 45% of the deal flow in the three months ended December 31, 2011 and later-stage deals made up roughly 55% of the deal activity in the quarter.
