How would you apply a cost–benefit analysis to risk treatments?

• A. Compare the cost of controls to the total revenue of the company.
• B. Ignore the likelihood of risk reduction and only consider implementation cost.
• C. Compare expected risk reduction value and avoided losses to the cost of controls; decide based on net benefit.
• D. Choose the most expensive control to maximize perceived value.

Answer: (C)

In applying cost–benefit analysis to risk treatments, the key is to compare the value of the risk reduction with the cost of the controls to determine the net benefit. Start by estimating the expected loss from the risk before any treatment (probability of the event times its impact). Then estimate how much the control reduces that risk—the expected reduction in losses or avoided losses—and add any other monetary benefits from preventing the event. Next, total the costs of implementing and operating the control (initial investment, ongoing maintenance, and any side effects). The core decision is based on net benefit: if the benefits exceed the costs, the treatment adds value; if not, reconsider options. This approach matters because it combines likelihood and magnitude of risk with the true cost of mitigation, rather than looking at costs alone or at risk reduction in isolation. Choices that focus only on revenue, ignore probability of risk reduction, or pick the most expensive option do not reflect the net value of a risk treatment.
