(66)In order to ensure that the design of remuneration policies is integrated in the risk management of the institution, the management body should adopt and periodically review the remuneration policies in place. The provisions of this Directive on remuneration should reflect differences between different types of institutions in a proportionate manner, taking into account their size, internal organisation and the nature, scope and complexity of their activities. In particular it would not be proportionate to require certain types of investment firms to comply with all of those principles.
