No charts. Just a decent letter from CEO Lloyd Blankfein to the FT on mistakes and lessons. Excerpts:

.This over-dependence on credit ratings coincided with the dilution of the coveted triple A rating. In January 2008, there were 12 triple A-rated companies in the world. At the same time, there were 64,000 structured finance instruments, such as collateralised debt obligations, rated triple A. It is easy and appropriate to blame the rating agencies for lapses in their credit judgments. But the blame for the result is not theirs alone. Every financial institution that participated in the process has to accept its share of the responsibility.

We did so because our self-interest in preserving and expanding our market share, as competitors, sometimes blinds us – especially when exuberance is at its peak.
