In risk management, which term describes how often an event is expected to occur in a year?

• A. Annual Rate of Occurrence
• B. Annual Rate Of Occurrence
• C. Annual Occurrence Rate
• D. Annual Rate of Occurrence

Answer: (D)

The main idea here is frequency: how often an adverse event is expected to happen within a single year. The term used to describe that yearly frequency is the Annual Rate of Occurrence. It clearly conveys a rate per year, which is exactly what you need when estimating annual risk and losses (for example, ALE = SLE × ARO). While the other phrasings may express a similar idea, the standard terminology in risk management is Annual Rate of Occurrence, making it the best fit.
