Vincent Schmeltz, a former of counsel for Dewey & LeBoeuf, testified Monday at the trial of the firm’s top executives about some of the billing matters for which he was responsible in 2010 and 2011, the years before the firm’s collapse.

The prosecution asked Schmeltz about an April 2011 email he sent to former chief financial officer Joel Sanders and executive director Stephen DiCarmine, among others, in which he alerted the executives that $6.9 million in fees associated with the Securities and Exchange Commission’s case against WexTrust Capital had not been written off.
