Bloomberg reports that Villhauer is referred to only as the 'Head Trader' in a Securities and Exchange Commission complaint filed November 20th in Manhattan federal court against Mathew Martoma, said the people, who declined to be identified because the matter isn’t public. He is referred to in an FBI complaint filed that same day as the 'Senior Trader'. Martoma denies wrongdoing. Villhauer hasn’t been charged or sued.

'The government will see him as either a potential cooperator against others or as a worthy target by himself'.
