Thomas Mullikin, one of the seven former Dewey & LeBoeuf employees who pleaded guilty and agreed to cooperate in an investigation of the firm’s former leaders, testified Wednesday that he had falsified the firm’s accounting records.

In a straightforward tone with little expression, Mullikin told the jury that he was instructed to alter Dewey & LeBoeuf’s records at the beginning of 2009 in order to make it appear that the firm’s net income was greater than it really was in 2008. Under questioning from Steve Pilnyak, an assistant district attorney with the New York County District Attorney’s Office, Mullikin said this was done so Dewey & LeBoeuf would avoid breaking covenants it had with four banks.
