Question 1

What is the main limitation of relying solely on internal loss data for operational risk capital modeling?

Accepted Answer

Internal loss history may be too short or lack sufficient large-loss observations, underestimating tail risk

Answer

Internal loss histories are often short and may not include extreme tail events, so relying solely on them can underestimate the true severity of rare, high-impact losses.

Question 2

How does the use of external loss data address the limitations of internal data in operational risk modeling?

Accepted Answer

External data supplements internal data to improve the estimation of low-frequency, high-severity loss distributions

Answer

External loss data provides observations of rare, large-scale loss events at peer institutions, which helps calibrate the tail of loss distributions that internal data cannot capture.

Question 3

What is a Monte Carlo simulation used for in operational risk quantification?

Accepted Answer

To generate thousands of random loss scenarios by sampling from frequency and severity distributions to estimate aggregate loss distributions

Answer

Monte Carlo simulation uses repeated random sampling from loss frequency and severity distributions to build an aggregate loss distribution and estimate percentile-based capital figures.

Question 4

Which of the following is a key governance control for managing model risk in a financial institution?

Accepted Answer

Maintaining a comprehensive model inventory with periodic validation and performance monitoring

Answer

A centralized model inventory that tracks all models in use, their purpose, validation status, and ongoing performance is a foundational model risk governance control.

Question 5

What does 'backtesting' a risk model involve?

Accepted Answer

Comparing model predictions or outputs against actual historical outcomes to assess accuracy

Answer

Backtesting compares a model's predicted outcomes against realized historical results to evaluate whether the model's assumptions and outputs are accurate.
