OK, I have absolutely no idea what your acronyms mean (other than lit=litigation, I think). Please inform me so I won't feel like such an idiot in the future.
S&C = Sullivan & Cromwell
DPW = Davis, Polk, & Wardwell
STB = Simpson, Thacher & Bartlett
M&A = Mergers & Acquisitions
PE = Private Equity
None of these are particularly obscure, so probably good to add them to you lexicon...
