By Sarah McBride SAN FRANCISCO (Reuters) – Investors in March fired G. Steven Burrill as the head of a $283 million venture-capital fund he ran, amid alleged fraud and misuse of capital, according to a lawsuit. The lawsuit, filed last week in state court in San Francisco, comes at a time when the Securities and Exchange Commission is taking a hard look at hidden fees at private equity funds, although the investigation has not yet touched venture-capital funds. Private equity funds tend to be larger and invest at later stages than do venture funds. The lawsuit was brought by Ann Hanham, until November a managing director at the firm, and alleges that $19.2 million in unauthorized payments were made to Burrill or his affiliates from a fund launched in 2006 called Fund III. Two Burrill colleagues, chief legal counsel Victor Hebert and Chief Financial Officer Helena Sen, knew about the transactions, the lawsuit alleges.
