What does the A-List really measure? In some ways it’s like a decathlon for law firms, a contest that tests their strengths in a variety of exacting ways, although we’ve yet to ask firms to clear a high jump. Instead, the factors that go into the tenth edition of this annual ranking—revenue per lawyer, pro bono, associate satisfaction, and diversity—aim to identify firms that represent the all-around best. While financial strength is important (and reflected in the RPL factor), we also want to applaud firms that are committed to serving the less fortunate, and to creating a diverse and healthy work environment.

What does topping the A-List mean to the chair of Hughes Hubbard & Reed, which leads our A-List for the second year in a row? “The A-List ranking measures our success as a firm in more than just dollars. So do we,” says Candace Beinecke. “If money is the only thing holding a firm together, you’ve really got nothing. There always are those who have more and many who have less.”
