8 Risk Management Task Force Update Agenda Sub Group Updates Equity Modeling Policyholder Behavior Economic Capital Risk Metrics Risk Covariance Health Risk 15 Equity Modeling 1. Subgroup Focus: With the introduction of new product designs in recent years, equity risk is quickly outpacing interest rate risk as the dominant market risk in insurance company portfolios 1. Task 1 to assess the kinds of modeling tools and techniques available to measure equity risk 2. Task 2 - to provide a comprehensive description of such techniques, along with identification of parameters and assumptions 3. Task 3 To identify the pros and cons of each approach used to manage equity risk 2. Ultimate Product To develop a practical guide for modeling and managing equity risk geared towards actuaries 16 8

9 Equity Modeling - Update Created an annotated reading list and posted to the web site. Identify a list of about twelve gaps, and have addressed about half of them so far. Is there further materials that would address the gap, whether material should be commissioned to fill the gap or whether we should identify it as a topic for future consideration. We have a few hard core members who have been active throughout the piece, but also welcome new members to bring us new energy and new ideas. 17 Equity Modeling Gaps Topic 1: Equilibrium vs Non Arbitrage Models Topic 2: Markov Chain Topic 3: Parameter Estimation Topic 4: Correlations Topic 5: Random Number Generation/ Variance Reduction Techniques Topic 6: Monte Carlo Simulation Topic 7: Risk neutral (Q) vs. Real World (P) Valuations Topic 8: Stock Indices vs Actively Managed Funds Topic 9: Currency Risk Topic 10: Model Validation Topic 11: Historical Simulation Topic 12: State Price Deflators Topic 13: Practical Application 18 9

10 Update from the SOA Risk Management Task Force Economic Capital Sub Group SOA Spring Meeting Washington, DC Session 25 Hubert Mueller Tillinghast Towers Perrin, (860) EC Subgroup One of the 10 subgroups within the Risk Management Task Force (RMTF) Goals To research measurement of economic risk in life insurance companies, practiced in North America To document techniques and standards that quantify the material risks of life insurance companies To document techniques for allocating risk capital for use in pricing, budgeting and financial reporting Participants Over 100 people on the listserve Generally, participants on regular conference calls Active participants provide a good mix of experience from insurers, consultants and rating agencies 20 10

11 Initial Working Products Industry survey on current practices related to EC Completed in the fall of 2002 Almost 500 participants Highlights discussed at the 2002 Boston Annual Meeting EC Specialty Guide Designed to be a source of information for practitioners Summarizes the results of the survey and provides additional insights by members of the subgroup Initial draft is now on website A work in progress 21 EC Specialty Guide Topics (Revised) Definition of Economic Capital Uses of EC in the current marketplace Tie-in of EC to regulatory/rating agency capital Current approaches to calculating EC Case studies (could use more) Regulatory developments (RBC C-3 II) Literature Review Ranked distribution of present values of future profits from each simulation $m + 0 Economic Capital Selected risk tolerance Cumulative probability 22 11

13 Risk Metrics Have produced a series of papers defining various risk metrics Risk Duration, Convexity Net amount at Risk Value at Risk Risk Based Capital Business Plan Risk Measures: Growth Rate, Unit Cost Earnings at Risk Option Adjusted Spread Embedded Value Greeks Latest paper Risk Exposure Limits In Process Risk Tolerance 25 Types of Exposure Limitations a. Event Specific b. vary by level of management c. can limit the exposure of a specific type of risk to a percentage of the total risk exposure. This would ensure total exposure is a combination of specific exposures that are not 100% correlated. d. limiting the exposure in any specific instance of a particular type of risk. e. can be used in contractual arrangements to describe how risk will be shared between two or more parties. f. can be used in combination with another risk management metric by placing a floor and or cap on that risk management metric. g. part of a flexible pricing process by adjusting prices up (or down) as the difference between the exposure limitation and the current exposure decreas es (increases). h. do not have to be monetary. Exposure limitations can also be used to limit operational risk or achieve operational objectives
