According to a new survey conducted by legal search consultant Major, Lindsey & Africa and Am Law Daily affiliate ALM Legal Intelligence, partners at Am Law 200, NLJ 350, and American Lawyer Global 100 firms saw their annual compensation rise, on average, 6.4 percent to $681,000 over the past two years. The jump was apparently driven, at least in part, by an uptick in the average rate those partners are billing, from $555 per hour in 2010 to $585 today.

The survey, which drew 2,228 responses from attorneys at the firms in question, shows that not all partners have benefited equally from the increase. On average, equity partners are better compensated than their non-equity counterparts, male partners make more than their female colleagues, corporate partners earn more than litigators, and partners in open compensation systems are paid better than those in closed compensation systems.
