The question is whether non-executive directors of banks should also be paid a regular or a fixed contractual remuneration. This is probably a good concept, but difficult to implement in practice. Typically, in banks, the outcomes of risks taken become manifest after a long gap.
While it is possible to align compensation of executives to the risks since they are long term employees, it is more problematic in the case of non-executive directors who serve for relatively shorter periods and have term limits.
