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. In 2009, venture capital-backed companies received, in approximately 2,400 transactions, equity financing in an aggregate amount of approximately $20.5 billion, representing a 32% decrease from the preceding year, as reported by Dow Jones VentureSource. In addition, overall, the median round size in 2009 was $5.0 million, down from $7.0 million in 2008. These decreases were primarily a result of contraction of the capital markets experienced during the past year. Overall, seed- and first-round deals made up 18% of the deal flow in 2009, and later-stage deals made up roughly 56% of all capital invested.
