Prudential supervisors in the affected financial markets began joint work late last summer to identify common deficiencies on which they and the firms should focus.
The supervisors concluded that the firms that suffered the most significant losses tended to exhibit common problems, including insufficiently close monitoring of off-balance-sheet exposures, inadequate attention to the implications for the firm as a whole of risks taken in individual business lines, dependence on a narrow range of risk measures, deficiencies in liquidity planning, and inadequate attention to valuation issues.
