Technology Investment and Risk Assessment
A financial services firm is considering investing $5 million in a new AI-powered fraud detection system. The system is expected to reduce fraud losses by $2 million annually. However, the system's accuracy depends on the quality of transaction data. The vendor claims a 95% detection rate with a 5% false positive rate. The firm's current fraud losses are $10 million per year. The false positives would require manual review, costing $100 per case. The firm processes 1 million transactions per year. The system has a 10% chance of failing to integrate with the existing core banking system, which would result in a $1 million write-off and no benefits. The firm's cost of capital is 8%. The system has a useful life of 5 years.

First, calculate the number of fraud cases: Current fraud losses = $10M. Assume average loss per fraud case is not given, but we can work with total losses. The system detects 95% of fraud, so it prevents 0.95 × $10M = $9.5M in losses. However, it also generates false positives: 5% of 1 million transactions = 50,000 false positives. Cost of manual review = 50,000 × $100 = $5M. So net benefit before integration risk = $9.5M - $5M = $4.5M. But we must also consider the cost of the system: $5M investment, depreciated over 5 years? The $5M is a capital investment, so we should consider annual depreciation or the annual cost of capital. For simplicity, let's calculate the annual net cash flow: Savings from fraud reduction = $9.5M. Cost of false positives = $5M. Net annual cash flow = $4.5M. The $5M investment is upfront. So the annual net benefit is $4.5M. However, we need to account for integration risk: 10% chance of failure, resulting in $1M write-off and no benefits. So expected annual net benefit = 0.9 × $4.5M + 0.1 × (-$1M/5?) Actually, the $1M write-off is a one-time cost. So the expected NPV should be calculated. But the question asks for expected annual net benefit. We can compute the expected annual cash flow: 0.9 × $4.5M = $4.05M. The $1M write-off is a one-time cost, so it doesn't affect annual benefit but affects NPV. So expected annual net benefit = $4.05M. Alternatively, if we include the $1M write-off as an annual cost over 5 years, it would be $0.2M per year, so expected annual net benefit = 0.9×$4.5M + 0.1×(-$0.2M) = $4.05M - $0.02M = $4.03M. But that's not standard. The question likely expects: Expected annual benefit = 0.9 × ($9.5M - $5M) = $4.05M. Then subtract annualized investment? The $5M investment is upfront, so for annual net benefit, we might consider the annual cost of capital: $5M × 8% = $0.4M per year, or depreciation $1M per year. The question says "expected annual net benefit", which could mean net of all costs including capital. To be safe, we can compute the NPV and then the equivalent annual benefit. But let's stick to the simple interpretation: expected annual net cash flow before investment = $4.05M. Then subtract the annualized investment cost. The investment is $5M, and with 10% chance of failure, the expected investment is $5M (since even if it fails, the $5M is spent, plus $1M write-off? Actually, if it fails, the firm still spends $5M and then writes off $1M? That would be $6M total. But the problem says "$1 million write-off", which might mean additional cost. So expected investment = $5M + 0.1×$1M = $5.1M. Annualized over 5 years at 8%: use annuity factor. Annuity factor for 5 years at 8% = (1 - 1/1.08^5)/0.08 = 3.9927. So equivalent annual cost = $5.1M / 3.9927 = $1.277M per year. Then expected annual net benefit = $4.05M - $1.277M = $2.773M. But the question might not require discounting. Alternatively, simple annual depreciation: $5.1M / 5 = $1.02M per year. Then net annual benefit = $4.05M - $1.02M = $3.03M. Given the ambiguity, I'll provide a clear calculation: Expected annual fraud savings = 0.95 × $10M = $9.5M. Expected annual false positive cost = 0.05 × 1,000,000 × $100 = $5M. Net annual benefit before integration risk = $4.5M. Expected annual benefit considering 10% failure = 0.9 × $4.5M = $4.05M. The $1M write-off is a one-time expected cost of 0.1 × $1M = $0.1M, which can be annualized over 5 years as $0.02M per year. So expected annual net benefit = $4.05M - $0.02M = $4.03M. Then subtract annual depreciation of $5M/5 = $1M to get accounting profit, but the question says net benefit, likely cash flow. So I'll present the expected annual net cash flow as $4.03M, and note that the initial investment is $5M. For a complete analysis, NPV = -$5M + $4.03M × 3.9927 = -$5M + $16.09M = $11.09M. So the project is positive NPV.
2. What additional risk factors should the firm consider, and how might they affect the decision?

Additional risks: (1) Model risk: The AI may become less accurate over time due to changing fraud patterns, requiring retraining and additional costs. (2) Data privacy and regulatory compliance: Handling sensitive transaction data may require additional controls and audits. (3) Vendor risk: The vendor may go out of business or change pricing. (4) Integration complexity: Even if integration succeeds, it may take longer and cost more than expected. (5) False positive rate may be higher in practice, leading to higher manual review costs and customer dissatisfaction. These risks could reduce the expected benefits or increase costs. A sensitivity analysis should be performed, and a pilot or phased rollout could mitigate risks.
