ProHub Comment

This case tests profitability analysis and mental math rigor. The interviewee must carefully structure a comparison of expected profits between two systems, accounting for approval rates, bad loan rates, and operational costs. The non-obvious insight is that despite lower approval rates and higher per-loan costs, the new system generates higher profits due to dramatically reduced bad loans.

Your client is a bank that is considering changing their loan issuing operation to a new system. They would like you to evaluate the pros and cons of each system, and advise them on how to proceed.

  2. The average value of a loan is $10,000
  3. The proposed program has a 40% acceptance rate
  4. The original program resulted in about 10% bad loans
  5. The proposed program would result in only 5% bad loans (due to higher scrutiny at the central office)

A bank is evaluating whether to eliminate branch-level background checks and consolidate all screening at the central office. The new system has higher per-application costs ($110 vs $100) and lower approval rates (40% vs 45%), but results in fewer bad loans (5% vs 10%). The candidate must calculate expected profits for each system and recommend whether to proceed.

Key Insights:

  1. Expected profit for original system: $485,000; expected profit for new system: $550,000
  2. The new system’s profitability advantage comes from quality improvement (5% bad loans vs 10%), not from volume
  3. Beyond financials, consider non-financial factors: regulatory requirements for multiple checks, training needs for centralized staff
  4. Mental math discipline is critical—tracking multiple percentages and multiplications can easily lead to calculation errors
