FYI: The lessons here are fairly obvious: Losing some like Gross or Gundlach is a loss for the parent company. If handled intelligently, the damage can be minimized. However, an acrimonious, public firing accompanied by litigation can inflict long-term damage. For both TCW and Pimco, the firings had troubling ramifications for both the departing manager's funds, and the companies overall.
