FRM Part I · FRM Exam Part I · Operational Risk

A bank estimates operational loss frequency as Poisson with mean 20 events per year. Each event has severity of USD 0.5 million on average. After new controls, frequency falls by 30% and the average severity falls by 20%. The controls cost USD 1.5 million per year. What is the net annual benefit of the controls in expected-loss terms?

The net benefit is USD 2.9 million, computed as the 4.4 million reduction in expected loss minus 1.5 million of cost.

  1. AUSD 2.8 millionCorrect
  2. BUSD 4.4 million
  3. CUSD 5.6 million
  4. DUSD 3.0 million

Explanation

Original expected loss = 20 × 0.5 = 10 million. New = 14 × 0.4 = 5.6 million. Reduction = 4.4 million. Net of cost = 4.4 - 1.5 = 2.9... recompute: 14 × 0.4 = 5.6; 10 - 5.6 = 4.4; 4.4 - 1.5 = 2.9. The 2.8 option is therefore wrong, and the nearest correct value is not listed.
