Derish Wolff, the former president, CEO, and chairman of Louis Berger Group, was sentenced to 12 months of home confinement and fined $4.5 million for conspiring to defraud the U.S. Agency for International Development (USAID) with respect to billions of dollars in contracts over a nearly 20-year period. Wolff pleaded guilty to leading a conspiracy to defraud USAID from at least 1990 through July 2009 by billing the agency on cost-reimbursable contracts—including contracts for reconstruction work in Iraq and Afghanistan—for overhead and other indirect costs at falsely inflated rates.
