What in the world? Believe me, 12 attorneys are not working on this 40 hours per week. Most likely the associates are putting in a few hours apiece and their work is routinely reviewed by the partners. Plus, why is it a contribution? Where do you think the money borrowed for litigation is being spent?
Partners at R & G billed $800 per hour 10 years ago, partners at top law firms are closer to $2000 per hour now (Google it, you'll see).
