It will be a cold day in hell before you can get that kind of info. Law firms here don't even want to disclose their financials when tendering for government work, and often try to worm their way out of providing it.

I also suspect that if the big firms start to reveal their PEP, there will be a lot of very dissatisfied junior equity partners looking to move when they find out how badly they've been shafted by the lao jiao "inner circle".
