The top performing law firms continued to pull away from the rest of the Am Law 200 last year, according to a report released Monday by Wells Fargo Private Bank’s Legal Specialty Group. Meanwhile certain regions, including the mid-Atlantic states, struggled to achieve even modest revenue growth.

Law firms in the top half of the Am Law 100 saw revenues rise an average of 5 percent, the report said. The whole of the Am Law 100, a list of the top 100 grossing law firms, saw revenues rise almost 4 percent, while firms in the Second Hundred, which includes the 101st through 200th grossing firms, grew 1 percent in 2016.
