Leadership at Am Law 100 law firms remains concentrated in the hands of older baby boomers and members of the Silent Generation, born before the end of World War II. But leadership at Fortune 100 and Nasdaq companies is already transitioning to younger boomers and Generation X chief executives and general counsel, according to data from The Am Law 100, the Fortune 100 and Nasdaq companies compiled by Heather Morse, marketing director at Greenberg Glusker Fields Claman & Machtinger.

Almost 20 percent of Fortune 100 and 30 percent of Nasdaq general counsel are Gen X members compared with fewer than 5 percent of Am Law firm leaders, Morse found.
