  4. Risk Modeling Application A Research Question Sample Company - background - modeling assumptions Coherent Risk Measures Conclusions

  5. A Research Question Question: Does recording a reserve higher than management’s best estimate have an effect on the capital required to support the company’s operations? One Answer: Model the company’s financial risk under different reserving strategies. Calculate the level of capital required to support operations.

  6. Company Example • Initial Policyholder Surplus = $70MM • Writes approximately 2 to 1 • Modest Business Growth (3-6%) • Risk Factors • Economic Variables • Interest • Inflation • Pure Loss Variability • Five Year Projections of Operating Results

  7. Economic Risk Factors • Cox-Ingersoll-Ross Interest Rate Generator • Mean-reverting random walk for interest rates • Cascading dependency of inflation rates • Linear relationship with error term it =m . rt + b+ e Interest Rates Inflation

  8. Reserve Variability • Reserve adequacy defined by expected inflation rate • Actual (generated) inflation rate provides hindsight reserve • For example: • 6.0% expected inflation at 12/31/00 • 6.2% generated in 2001 • Effect of unanticipated 0.2% of inflation is calculated over life of reserve. Adverse development occurs.

  9. Company Reserving Policy • Three Reserving Practices Examined • Mean level reserving • 75th percentile reserving • 90th percentile reserving • Management Reserving Practice: Eroding Margin • Each year absorb any adverse reserve developments up to 50% of remaining margin • For example: $5MM prior year “hit” reduces any available margin by $2.5MM. The other $2.5MM flows to income.

  10. Simulated Financial Results Parameterized, Validated, What the actuary fusses over Decision-Making Performance measures Risk measures Consistent with financial world Coherent Risk Measures From DFA simulations to financial decisions. How do we get there? ?

  11. Coherent Risk Measures Article – 1994 AFIR Colloquium • Clarkson: “The Coming Revolution in the Theory of Finance” • Van Slyke’s review 1995: “Need to consider total distribution”

  12. Coherent Risk Measures • “Coherent Measures of Risk” • Philippe Artzner, Freddy Delbaen, Jean-Marc Eber and David Heath, Math. Finance 9 (1999), no. 3, 203-228 • http://www.math.ethz.ch/~delbaen/ftp/preprints/CoherentMF.pdf • Coherent Measures of Risk - An Explanation for the Lay Actuary • Glenn Meyers • http://www.casact.org/pubs/forum/00sforum/meyers/Coherent%20Measures%20of%20Risk.pdf

  13. Coherent Risk Measures Swiss Paper (Artzner, et al) • Setting margin requirements on exchange • Similar to capitalization of insurer • Based on four axioms • “Coherent”: in the eyes of the beholders?

  14. CRM - Survey of Risk Measures Standard Deviation Value-At-Risk Expected Policyholder Deficit

  15. CRM - Standard Deviation Material departures from normal behavior can lead to problems Includes upside variation • The free lottery ticket “costs too much”

  16. CRM - Value at Risk The value at a selected quantile Problems • The most extreme values are ignored • Doesn’t distinguish between tails • Can mislead when combining risks

  17. Coherent Risk Measures So, What Would Make More Sense? • Guiding question: How big is “big”? • Guiding Principle: The purpose of capital is to fund prospective losses • Try “Tail Value-at-Risk”

  18. Tail Value at Risk is the average of all losses above the Value at Risk

  19. Results of Modeling Base Case with Constant Percentage Margin

  20. Results of Modeling Base Case – Eroding Margin

  21. Results of Modeling Higher Economic and Reserve Variability

  22. Other Tests Under Examination • Longer Reserve Durations • Under best estimate reserving, the company needs more capital • Using greater margins, capital requirements are eventually reduced

  23. Conclusions • Reserve margins can be used to stabilize income and reduce capital requirements • The reduction in reported capital is offset by lower requirements due to the hedge which a margin can offer • Accounting, regulatory, and other external realities limit the extent to which margins are possible and desirable

  24. Reserve Margins and Capital Casualty Loss Reserve Seminar New Orleans September 11, 2001 Chandu C. Patel, FCAS, MAAA

  25. Reserve Margins and Capital – The CFO Perspective Statutory considerations for reserve margins • Codification requires that held reserves should correspond to Management’s best estimate. • Ideally, this would correspond to the actuarial best estimate. • Although the intent is to prevent “low” end reserves, “high” end reserves also require documentation. • Generally, on an on-going basis, statutory framework (e.g. IRIS ratios) favors high end reserves.

  26. Reserve Margins and Capital – The CFO Perspective GAAP considerations for reserve margins • Typically reserves are many multiples of earnings • As a result, any movement within the actuarial range has a significant impact on earnings; this can be construed as earnings management • To maintain a consistent reserving philosophy, this would suggest that held reserves should be based on the actuarial range and at a consistent percentile of the range • In fact if a high percentile is targeted, this may lead to greater variability in results – need model to evaluate

  27. Reserve Margins and Capital – The CFO Perspective IRS considerations for reserve margins • Generally, IRS is not sympathetic to conservative reserves. However actuarial range may provide adequate justification for high end reserves • Utah Medical – actuarial range accepted • Minnesota Lawyers – actuarial range not considered • No clear case history

  28. Reserve Margins and Capital – The CFO Perspective AM Best and Other Ratings considerations for reserve margins • Reserve adequacy has a significant impact on BCAR • Rating agencies place a lot of emphasis on reserve adequacy • Consistent, favorable development of past estimates will lead to higher rating

  29. Reserve Margins and Capital – The CFO Perspective Risk Based Capital considerations • Formulaic approach considers held reserves as “best estimate” even though there may be a margin in the reserves • Hence Company is penalized in terms of lower statutory surplus and higher RBC • Offsetting effect is favorable loss development

  30. Reserve Margins and Capital – The CFO Perspective TVAR adjusted for reserve margin • Based on model output, given the ability to release reserves per the model assumptions, it is clear that the higher the percentile of held reserves, the lower the TVAR. • Release of reserve margins leads to reduced variability as the margin provides a cushion for adverse scenarios. • This would suggest that a high reserve margin is desirable form a TVAR perspective. • However, end position reflects an erosion in the margin and this has to be “replenished” if the original reserve margin is to be maintained.

  31. Reserve Margins and Capital – The CFO Perspective Average ROR and CV of Net Income • High margin implies lower surplus leading to a higher return; the reverse is true for lower margins • In addition, reserve release increases the average net income as well. This leads to a higher numerator and a higher average return • Reserve release also reduces the variability of net income since adverse outcomes are cushioned. • All indicators point to a strategy of holding a high a reserve margin, based on the model assumptions • Once again erosion of reserve margin and perception of “earnings management’ have to be considered as well.

  32. Reserve Margins and Capital – The CFO Perspective Summary of considerations • External Factors – Statutory guidelines, Statutory Surplus/RBC, SEC, IRS, AM Best • Internal Factors – TVAR, Goal for earnings stability, “cost” of capital • Other – If pricing is based on conservative reserves, implications of future profits • Other – If investment decisions are based on whether funds are considered “reserves” or “surplus”, impact on investment income

  33. A DFA Approach to Valuing a Run Off OperationCAS CLRS September 11, 2001 Kevin Madigan MHL/Paratus

  34. A DFA Approach to Valuing a Run Off Operation • ABC Insurance Companies wants to put a book(s) of business into run-off • Reasons for such action include: • A management decision to exit a market • A need to segregate a collection of policies from ongoing operations (asbestos, construction defects, etc.) • Let’s assume ABC wants to sell this run-off operation (possibly to a subsidiary)

  35. A DFA Approach to Valuing a Run Off Operation We are assuming that ABC is selling the run-off operation to a buyer who will set it up as an insurance company or companies. However, most of the following applies if ABC is setting up a run-off business unit.

  36. A DFA Approach to Valuing a Run Off Operation Q: Why buy it? A: To take cash out of it

  37. A DFA Approach to Valuing a Run Off Operation Sound, aggressive, focused approaches to • Claims settlement • Commutations • Investments Allow for significant annual “dividends” & an extraordinary one “at the end of the day”.

  38. A DFA Approach to Valuing a Run Off Operation What’s a good price?

  39. What’s A Good Price? The only appropriate actuarial answer is:

  40. What’s A Good Price? Well ...

  41. What’s A Good Price? Well ... ...that depends.

  42. What’s A Good Price? What does it depend on? • The liabilities Gross, net, and ceded loss & LAE, and the adequacy of the reserves • Payment patterns (and how many more years?) • “Bad debt” – i.e. how collectable is/will be the cessions? When and how will this be recognized? Schedule F issues? • What has been commuted, and for how much?

  43. What’s A Good Price? What else does it depend on? • Investment Income • RBC • General Expenses • Income and Other Taxes • Paid-in Capital • Additional Reinsurance • etc.

  44. What’s A Good Price? Probably the most important factors are • The parties’ risk appetites • The perceived adequacy of the reserves These factors cannot be modeled But all is not lost

  45. What’s A Good Price? • Build stochastic model assuming yearly dividends. • No way to definitively determine a “good price” for all possible players. • Produce distributions of the NPV of future dividends using various term structures.

  46. What’s A Good Price? If the model’s assumptions are reasonable, then the table says that a $16M price provides the buyer with • An 80% prob of a return of 4% or better • A 40% prob of a return of 16% or better, etc. Whereas a $21M price provides the buyer with • A 50% prob of a return of 4% or better • A 20% prob of a return of 20% or better, etc.

  47. What’s A Good Price? Alternatively, if one requires, say a 14% ROR, then the table can be used to evaluate possible purchase prices (e.g. $15M gives only a 50% probability of meeting the required ROR; $10M gives an 80% probability, etc.).

  48. Other Issues At the time of purchase, the buyer gets more than just the reserves. There has to be some associated capital to support the operations. The amount of this paid in capital will greatly affect the surplus of the new run-off entity, and will have an impact on the size of the yearly dividends.

  49. Other Issues Too little capital  Low purchase price Very little inv. income Small or zero dividends Surplus and RBC issues Too much capital  High purchase price Drain on seller’s assets
