Thomas Russo knows a thing or two about shepherding struggling financial companies through chaotic times. The former top lawyer for Lehman Brothers Holdings Inc. took on the unenviable task of becoming general counsel for embattled American International Group Inc. in February.

Now Russo’s old life as head lawyer of the collapsed Lehman Brothers is in the news again with the release of a 2,200-page bankruptcy examiners’ report. The New York Times called it the “Wall Street equivalent of a coroner’s report” because it lays out in minute detail how Lehman Brothers used accounting gimmicks to hide the bad investments that led to its demise.
