Actually the comment I was responding to was about "running a tight shop" -- which is about operational integrity in general (not just on the matter of unhedged risk).
In the, you know, "would you buy a used car from these guys?" sense.
Perhaps a difference of definition but I don't consider a tight shop to have anything to do with morals or integrity. Tight shops I always considered efficient and optimized. Car dealerships are shady, but they can run a tight shop.
The only reason GS is still around is because they did what they did. They protected their shareholders the fine is trivial (less than 10%) compared to the losses they would have taken if they followed the course of action that everyone else did.
Operational integrity for investment bank is to a very significant degree risk management. Integrity as in having control over something not in a moral sense. In the case you referenced I'd rather see GS's counterparties taking more blame. The whole we are poor guys running multi-billion dollar funds and charging millions in fees didn't do due diligence and want to blame someone else thing is pure BS.
