The stately regatta that is The Am Law 100 kept sailing at a good clip in 2016, but is starting to encounter some unpredictable conditions.

The 2016 Am Law 100 results were rather impressive for an industry facing a number of headwinds, not least of which was flat demand for their lawyers’ time. As a group, the nation’s largest firms managed to grow revenue by 4.3 percent, compared to 2.7 percent a year ago. And profits per equity partner rose by 3.0 percent, slightly behind last year’s 3.9 percent increase.
