Explain the concept of loss development factors and how they are used in reserving.
How to Answer
- 1
Define loss development factors clearly and briefly.
- 2
Explain their role in estimating future claims.
- 3
Mention how they adjust historical data to project reserves.
- 4
Provide an example to illustrate their application.
- 5
Emphasize the importance of accurate development factors in reserving.
Example Answers
Loss development factors are statistical tools used to estimate how much more we expect to pay on claims that have been reported but not fully settled. They help adjust past claims data to project the total reserves needed for future payments.
What are the differences between deterministic and stochastic reserving models?
How to Answer
- 1
Define both types of reserving models clearly.
- 2
Highlight the key characteristics of deterministic models.
- 3
Explain the main features of stochastic models.
- 4
Discuss the advantages and disadvantages of each.
- 5
Provide examples of when each model might be used.
Example Answers
Deterministic reserving models use fixed assumptions to estimate reserves, giving a single point estimate. In contrast, stochastic models incorporate randomness and provide a range of possible outcomes, allowing for better risk assessment. Deterministic models are simpler but less informative about uncertainty, while stochastic models capture variability and measurement error, which can be critical for complex portfolios.
What statistical techniques do you use to analyze claims data for reserve estimation?
How to Answer
- 1
Discuss specific techniques like chain-ladder or Bornhuetter-Ferguson.
- 2
Mention the importance of credibility theory in your analysis.

- 4
Emphasize data cleaning and validating steps in your process.
- 5
Talk about the importance of understanding the underlying patterns in the data.
Example Answers
I primarily use the chain-ladder method for reserve estimation, as it effectively captures the development of claims over time. I also apply generalized linear models to account for various predictive factors affecting future claims.
How would you apply Generalized Linear Models (GLM) in the reserving process?
How to Answer
- 1
Explain the purpose of GLMs in predicting claims and loss development.
- 2
Discuss the relevance of selecting appropriate link functions for different types of data.
- 3
Mention how GLMs can adjust for exposure and covariates in the reserving process.
- 4
Provide an example of a claim frequency model versus a claim severity model.
- 5
Highlight the importance of model validation and diagnostics to ensure accuracy.
Example Answers
In reserving, I would use GLMs to estimate the outstanding claims by analyzing historical data. I would choose a log link for frequency models and a gamma distribution for severity. This helps to effectively adjust for varying levels of exposure and claims characteristics.
Can you describe the chain ladder method and its application in reserving?
How to Answer
- 1
Define the chain ladder method clearly and simply.
- 2
Explain its purpose in estimating reserves for claims.

- 5
Provide examples of how it helps actuaries in decision-making.
Example Answers
The chain ladder method is a technique used for reserve estimation in insurance. It uses historical claims data arranged in loss triangles to project future claims. By applying development factors derived from the historical data, actuaries can estimate ultimate losses and required reserves effectively.
What methods do you use to assess the adequacy of reserves?
How to Answer
- 1
Start by mentioning key reserving methods like the chain-ladder and Bornhuetter-Ferguson.
- 2
Explain how you assess loss development factors to estimate ultimate losses.

How to Answer
- 1
Define the Bornhuetter-Ferguson method clearly.
- 2
Explain its key components: expected loss and reported loss.
- 3
Mention scenarios where this method is ideal, like immature losses.
- 4
Highlight benefits, such as stability in reserving estimates.
- 5
Discuss limitations, such as the reliance on assumptions of expected loss.
Example Answers
The Bornhuetter-Ferguson method combines expected losses with actual reported losses to estimate reserves. It is particularly useful for newer claims or when historical data is limited, as it relies on an expected loss ratio along with the incurred loss.
Why is discounting applied in reserve calculations and how do you perform it?
How to Answer
- 1
Explain the purpose of discounting to reflect the time value of money
- 2
Mention the key factors impacting the discount rate such as risk-free rate and risk premiums
- 3
Describe how to apply discounting using actuarial methods like DCF (Discounted Cash Flow)
- 4
Provide an example of calculating present value of reserves using a specific discount rate
- 5
Include the importance of updating assumptions regularly based on market conditions
Example Answers
Discounting is applied in reserve calculations to account for the time value of money, which means that a dollar today is worth more than a dollar in the future. I calculate reserves by applying a discount rate, often based on current risk-free rates, and use DCF techniques to determine present values.
