LEGAL TEAM AND OUTSIDE COUNSEL

General counsel Carrie Hightman’s department comprises “65-ish” employees, she said, including 39 lawyers besides herself. She has instituted a “core provider” program, relying on a dozen key outside firms plus additional providers to address specialty needs. Among the core group are McGuireWoods (labor/employment, regional litigation); Schiff Hardin of Chicago (environment, corporate, securities); Reed Smith (regional litigation, commercial); Columbus, Ohio’s Porter Wright Morris & Arthur (employee benefits); Locke Lord (midstream mineral rights, natural gas); Chicago’s Winston & Strawn (federal matters, energy); and Atlanta’s Troutman Sanders (federal reg­ulatory). Hightman deals with state regulatory counsel wherever NiSource operates.
