Answer 7

Data governance – the overall management of the availability, usability, security and integrity of data employed in an organization

A data governance policy will set out guidelines with regards to:

1. The specific roles and responsibilities of individuals in the organization with regards to data
2. How an organization will capture, analyze and process data
3. Issues with respect to data security and privacy
4. The controls that will be put in place to ensure that the required data standards are applied

Question 8

List the main sources of data

Answer 8

TRAINERS

Tables
Reinsurers
Abroad (data from overseas contracts)
Industry data
National statistics
Experience investigations on the existing contract
Regulatory reports and company accounts
Similar contracts

Question 9

What is the overriding principle in relation to all the different uses of data?

Answer 9

There should be one single, integrated data system so that the data used for different applications is consistent

Question 10

Define algorithmic trading

Answer 10

This is a form of automated trading that involves buying and selling financial securities electronically to capitalize on price discrepancies for the same stock or asset in different markets.

(can also refer to high frequency trading)

Question 11

Explain the risks of algorithmic trading

Answer 11

1. Errors in the algorithm or data used to parameterize the model, leading to losses
2. The algorithm may not operate properly in adverse conditions
3. In very turbulent conditions, trading in individual stocks or markets may be suspended before algorithmic trade can be completed
4. Possible impacts on the financial system - failure of one market could impact other markets and asset classes..

Question 12

List the key risks associated with using data

Answer 12

1. Data are inaccurate or incomplete, leading to erroneous results or conclusions
2. Data are not credible due to insufficient volume, particularly for extreme outcomes.
3. Data are not sufficiently relevant to the intended purpose
4. Historical data do not reflect what will happen in the future (abnormal events; significant random fluctuations; not up to date; homogeneous groups change)
5. Chosen data groups are not optimal
6. Data are not available in an appropriate form for the intended purpose
7. Lack of confidence in the data leads to a lack of confidence in the results obtained from using it

Question 13

What two main factors cause data to be of poor quality and quantity?

Answer 13

1. Poor management control of data recording and checking
2. Poor design of data systems

Question 14

How can good quality data be ensured from an insurance proposal and claims form?

Answer 14

1. Questions should be well designed and unambiguous so that full information is given and so that applications / claims can be easily processed
2. Use questions with quantitative or tick-box answers wherever possible
3. Questions should be in the same order as the input into the administration systems, for quick processing of applications / claims
4. Ask the policyholder to verify the key information
5. All rating factors should be readily identifiable so that the composition of the final premium can be determined
6. Underwriting results should be added to the proposal form
7. Forms should be designed so that information can be easily analyzed, and cross checks made between the two sources

Question 15

Why is it important, at the time of the claim, to have access to the information given on the proposal form?

Answer 15

1. To check the validity of the claim
2. To update policy information

Question 16

Why is it important that the insurance company retains a past history of policy and claims records?

Answer 16

When an insurance company analyses past experience in order to help set future assumptions, several years’ worth of data are often needed in order to give a sufficient volume of data, or to identify trends

Question 17

What is the key problem with data for employee benefit schemes?

Answer 17

The actuary does not have full control over the data, as it is provided by the sponsor

The consequences of this may be poor quality or summarized data

NOTE: It is therefore particularly important to validate this type of data

Question 18

What four sources of data are useful in order to conduct a valuation of a benefits scheme?

Answer 18

1. Membership data on individuals who are currently receiving benefits and those who are entitled to in the future
2. Data from the previous valuation for reconciliation with current data to help validate the current data
3. Accounting data for information on asset values, benefit outgo and contribution income to help check other sources of data or in setting assumptions
4. A full listing of the actual assets held to enable an accurate valuation of assets and to check whether they are permitted by regulation or subject to regulatory restrictions

Question 19

Give examples of reconciliation checks that can be performed on data

Answer 19

1. Reconciling the total number of members / policies and changes in membership / policies using previous data and movement data
2. Reconciling the total benefit amounts and premiums and changes in them, using previous data and movement data
3. Where assets are held by a third party, reconciliation between the beneficial owner’s and custodian’s records
4. Reconciling shareholding at the start and end of the period, adjusted for sales and purchases, and bonus issues

Question 20

Give examples of cross-checks that can be performed on data

Answer 20

1. Checking movement data against accounting data, e.g. benefit payments
2. Checking membership data against accounting data, e.g. contributions
3. Checking asset data against accounting data, e.g. investment returns
4. Full deed audit, for example checking title deeds to large real property assets

Question 21

Give examples of reasonableness checks that can be performed on data

Answer 21

1. Checking the average sum assured or premium looks sensible for the class of business
2. Checking the average sum assured or premium against previous data
3. Checking for unusual values, impossible dates or missing records

Question 22

Give examples of spot checks that can be performed on data

Answer 22

1. Random checking of individual member or policy data
2. Checking individual assets or liabilities exist / are held on a given date
3. Checking that the correct value of an asset or liability has been recorded

Question 22

Outline three problems with using summarized data

Answer 22

1. The reliability of the valuation will be reduced, as full valuation of the data is impossible
2. Summarized data may miss significant differences between the nature of the benefits that have been grouped together
3. Summarized data cannot be used to value options and guarantees that apply at an individual level

Question 23

Reasons why industry data is not directly comparable

Answer 23

1. Different geographical and socio-economic markets
2. Different policies
3. Different sales methods
4. Different practices, e.g. underwriting and claims settlement processes
5. Different nature of data stored
6. Different coding of risk factors

Question 24

Four other problems with industry data:

Answer 24

1. Less detailed and flexible than internal data
2. More out-of-date than internal data
3. Data quality depends on the quality of the data systems of all its contributors
4. Not all organizations contribute, and those that do may not be representative of the market

Question 25

What is risk classification and what is its main aim?

Answer 25

Risk classification – a tool for analyzing a portfolio of prospective risks by their risk characteristics, such that each subgroup of risks represents a homogeneous body of risk.

The main aim of risk classification is to split data into homogeneous groups so that the experience of each group is more stable, and data can be more accurately used, for example to set premiums

Question 26

When is data ‘Consistent’?

Answer 26

Consistent means that when comparing the experience of one group of policyholders with another, say, the data used as a basis for the calculations for each group should be:

• Similar
• Preferably extracted from the same source
• Grouped according to the same criteria
• Equal in terms of reliability
