DESCRIPTION

Risk issues at property/casualty companies arise from fundamentally different risk drivers from those that affect life insurers. Non-Life ERM is far from just a clone of life-side ERM. While risk managers may employ concepts like duration, the treatment objective can be significantly different from common understandings and involve complex analyses of going-concern considerations, cash-flow volatility and liquidity issues. In addition P/C risk management critically focuses upon tail events and extreme outcomes and the intricate funding thereof. This presentation approaches risk management from the unique perspective of the general insurer, highlighting key methodological differences and recent advances in risk identification and quantification. A close look at prevailing risk metrics and presentation approaches is also provided.

Cashflows in P&C insurance

• The expected CF in a calendar year is the sum of the diagonal. Assuming a constant ultimate per origin year it is 26%.

• No new accident year would implicate– no new business– no renewals– no unearned premium

• A new accident year does pay out 74% and does reserve the other 26% the expected reserves remain unchanged. the expected cash-flow balance is 0

• Additionally the cash-flow is highly volatile• Matching strategies (Duration, cash-flow,..) don’t make sense

Cash flow P&C

• Cash flows of P&C insurance are totally different to the cash flow of life insurance:

– Considerably more volatility• Large claims• Catastrophe claims• Adverse run-off

– The expected cash flow is usually small

• A liquidity risk is not arising form a mismatch in duration but rather due to the volatility

• How can liquidity risk be assessed?

• How can the liquidity risk be managed?

Example of the liquidity risk on the basis of three paths

Liquidity gap arises from one extreme negative u/w cash flow or from two

medium negative cash flows.

Strategies on managing liquiditiy risks

• The liquidity risk is an asset/liability matching risk – market value of fungible assets < payment obligations

– The liquidity risk can arise out of• Decreasing market values• Insufficient fungibility• Increasing payment obligations

– The liquidity risk is a timing problem and due to this fact it can not be capitalized

• Strategies to decrease the risk can be set at the asset and the liabilites side– Asset side

• Matching of the asset cash flow can not lead to the target• Market values: Investments in less volatile assets• Fungibility: Investments in more liquid markets

– Liabilities side• Arrangements of the reinsurance contracts • Implementation of „Cash-Calls“

• The handling of liquidity risks defines a constraint but does not determine a whole strategy

Risk Matching

• The asset and liability risks have a only a small dependency

• There is a strong diversification effect between both sides

– Bad results on the one side are often balanced by good ones on the other side

– This diversification effect can be measured

• In this example the worst case scenarios are caused by the liability side

Risk Matching

• „Stand alone“ adds both risk capitals which were calculated separately • „Diversified“ determines the risk capital on the aggregated risk profile

– Sub-additivity RK(A+B) ≤ RK(A)+RK(B)

– With capital allocation methods (here TVAR) the diversified capital can be allocated back

• How can you find the optimal diversification?

Risk Matching

• To compare different risk strategies a comparison of the risk capitals is insufficient

• The (expected) return has to be compared against to calculate the performance/efficiency of the capital

– Economic Value Added (EVA™) =return – cost of capital * risk capital

– Return On Risk Adjusted Capital (RORAC) =return / risk capital

• Other constraints have to be considered additionally

– Business policy

– Accounts

Risk Matching - Summary

• Use the diversification potentials between risks– Between asset and liabilities– Within the asset side between the asset classes– Within the liabilities side between the lines of business

• The whole balance between several risk operators is important– A balanced influence on the overall result– Dependent on the risk aversion– In practice: Optimum at given risk capital

• Changes in the risk strategy have always consequences in all areas– Holistic ERM should be integrated in the company

• BUT: No blind trust in the models– Techniques are helpful to support decisions but not to replace them– Understanding the effects is essential – no Black-Box!– ERM must be lived – clear communication within the whole company is

necessary
