The cultural differences among U.K. and U.S. law firms are dwindling in some respects as compensation models are tweaked, legal technology is adopted more universally, and law firms expand around the globe.

The American Lawyer affiliate Legal Week reported last week that Allen & Overy would hold an open vote if and when the partners weigh in on the deal, meaning the firm would know how each partner voted.
