Avoid general statements
A line such as "we have a low appetite for compliance risk" gives a manager little to work with. People need to know what is acceptable and what is not when they make a decision.
Set measurable limits
Break appetite down by risk category and attach measures to each one. Examples include a maximum number of serious safety incidents, a minimum level of liquidity or a limit on exposure to one supplier.
Say what happens at the limit
State who is told when a limit is close or breached, and what they must do next. Review the statement when the strategy changes, and at least once a year.
