A federal jury on Thursday found four former Wilmington Trust executives guilty of orchestrating a scheme to hide hundreds of millions of dollars in bad loans from regulators and investors.

The 12-member panel convicted Robert V.A. Harra, David Gibson, William North and Kevyn N. Rakowski on 15 counts of fraud and conspiracy in a Wilmington courtroom after about a week of deliberations. The U.S. Attorney’s Office for the District of Delaware confirmed the verdict Thursday afternoon.
