IPOs, trade sales and liquidations: Modelling venture capital exits using survival analysis

This paper examines the dynamics of exit options for US venture capital funds. Using a sample of more than 20,000 investment rounds, we analyze the time to ‘IPO’, ‘trade sale’ and ‘liquidation’ for 6000 VC-backed firms. We model these exit times using competing risks models, which allow for a joint analysis of exit type and exit timing. The hazard rate for IPOs are clearly non-monotonic with respect to time. As time flows, VC-backed firms first exhibit an increased likelihood of exiting to an IPO. However, after having reached a plateau, non-exited investments have fewer possibilities of IPO exits as time increases. This sharply contrasts with trade sale exits, where the hazard rate is less time-varying. We further provide evidence on the impact of economic factors such as syndicate size and composition, geographical location and VC value adding, on exit outcomes.
