During a cost-benefit analysis for a proposed control, the annualized loss expectancy (ALE) without the control is $500,000. The control is expected to reduce the ALE to $100,000. The control implementation cost is $150,000, and the annual operating cost is $30,000. What is the net annual benefit of the control?
Trap 1: $400,000
This is only the ALE reduction, not net benefit.
Trap 2: $370,000
Incorrect subtraction.
Trap 3: $250,000
This ignores the operating cost.
- A
$400,000
Why wrong: This is only the ALE reduction, not net benefit.
- B
$220,000
Correct calculation: ALE reduction minus total annualized cost.
- C
$370,000
Why wrong: Incorrect subtraction.
- D
$250,000
Why wrong: This ignores the operating cost.
