First, why is the OP anonymous?
Also, when calculating bonus amounts, keep in mind it has a lot to do with retention and not profitability. Firms in '07 were losing attorneys very rapidly and had to open their wallets in an effort to keep people around. See, e.g., articles about S&C pushing a 30% yearly attrition rate.
The S&C rate was on the extreme end of the attrition spectrum. Peer firms had far lower rates.
I think other firms will one-up them and they will either pay a supplemental bonus or lose a ton of associates to the lateral market. The economy is down but biglaw profits have been doing well and partners are making more money, while associates work more hours than ever. The market won't support lowball bonuses like these.
Proof positive that you are still in law school. Other firms that will surely beat: Boies, Susman, Kirkland, and Irell.
Aside from those, all firms will happily fall in line.
Also, associates aren't necessarily working "more hours than ever." End of Q3 and Q4 has been very slow for many top firms (though not mine, thank god).
I'm not saying that these numbers are OK. I have no opinion. But the notion that the market will exceed Cravath is silly, at least for fall bonuses. Heck, I know plenty of V100s that didn't pay spring bonuses.
