A Changing environment
Preparing for Solvency II
Johannesburg, Feb. 2, 2007


Environment of the insurance industry in the European Union has
undergone fundamental changes in the past few years.

Deregulation in the 90ies gave the insurance companies more
freedom and independence:
 New Opportunities
 New challenges and increased self-responsibility

Insurance companies and regulatory authorities are equally affected
by the changes.

In-force regulations are only partly successful (insolvency of
Mannheimer!).

Under the name “Solvency II”, a new supervisory framework is being
developed on a European level.

Why new solvency regulations ?
Preparing for Solvency II
Johannesburg, Feb. 2, 2007
Michel Dacorogna
Page 3

In-force solvability rules have a number of deficiencies. Examples:
 Premium-based methods hardly reflect the true risk.
 Factor-based methods are unable to adequately take into
account complex forms of risk transfer.
 Investment risks is not included in the required solvency.
 Dependencies between assets and liabilities or between lines of
business are not taken into account.

As a result, there is an unrealistic or wrong estimation of capital
levels. On the other hand, insurers already have technically mature
methods for risk analysis and capital allocation.

Moreover: Because of different regulations, there are opportunities for
regulatory arbitrage between banking and insurance industry (e.g.
credit insurance).

Solvency II: Key elements
3-pillar structure, Pillar 1
Preparing for Solvency II
Johannesburg, Feb. 2, 2007
Michel Dacorogna
Page 4
Quantitative requirements

Solvency capital shall be derived from the actual total risk and shall
essentially correspond to the economic risk capital.

Market-based valuation approach (‚mark-to-market‘).

Distinction between minimum and target solvency capital.

Minimum capital determined by a simple standard model.

Target capital can be determined by internal risk models.
Supervisory system shall favor the use of such models.

Interplay of assets and liabilities shall be taken into account (ALM).

Supervisory process and internal risk management

Insurance companies shall be made responsible for implementing
risk management processes. Examples:
 Actuarial principles regarding reserving practice
 Asset Liability Management (ALM)

Supervisory processes are guided by capital requirements and the
actual capital margin (capital which counts towards meeting
requirements).
 Supervisory process shall be more guided by the individual risk
profile of a single company.
 Intervention zone between minimal and target solvency capital,
within which the supervisory authority can intervene before the
company falls short of the minimum solvability capital.

Market transparency and discipline

Aimed at increasing transparency in the insurance industry.

The goal of the disclosure of the actual risk and return situation is an
increase of the market transparency that shall lead to an increased
market discipline.

Strongly follows Basel II and future IFRS guidelines.

Remark: The EU Commission seems to be aware of the dangers
that increased disclosure requirements can have (e.g. capital drain
in the case of a deterioration of the risk situation of an insurance
company).

Context of Solvency II
Preparing for Solvency II
Johannesburg, Feb. 2, 2007

Page 7

Solvency II is part of a changing regulatory environment:
 Basel II (regulatory framework for banks)
 IFRS (International Financial Reporting Standard, currently
under development)

Solvency II is an European project:
 Solvency II is initiated and driven by the EU Commission.
Solvency II is developed in close cooperation with national
supervisors and international professional bodies (e.g.
actuaries).

Solvency II is an ambitious project:
 Aims at a risk-based determination of adequate capital levels.

Solvency II is still under development. In force by 200X or 20XX only.

The Swiss Solvency Test

Page 8

In May 2003, the Swiss Federal Office for Private Insurers (FOPI)
together with the Swiss insurance industry launched the SST project.

The aim of the project was to elaborate a risk-based solvency
regulation.

For once, the Swiss were faster than the rest of Europe!:
 initial concept in December 2003
 further refined up to May 2004
 Field-test runs with 45 insurers (90% of the market) in 2005
 Insurance Supervision Act became legally binding as of 2006
 Full SST calculation for small insurers and Reinsurers by 2008

After a transition period of five years the solvency targets have to be
met by 1 January 2011.

thousands of interacting
outcomes of selected risk

The output is a range of
possible values with their
respective likelihoods instead
of a single “point” estimate.

Reinsurance Protection
Preparing for Solvency II
Johannesburg, Feb. 2, 2007
Michel Dacorogna
Page 15

For an insurance company, reinsurance is a substitute for capital.

The main drivers of strategic reinsurance are:
1. Protection of the available capital, we need to keep our RBC
within reasonable ranges of the available capital.
2. Diversification effect resulting in more effective use of our RBC.
3. Reduction in RBC, leading to a reduction in Cost of Capital.

The basis for designing a reinsurance program is the internal model,
where the RBC for the different risks is calculated.

We judge the efficiency of a reinsurance-cover against the cost of
capital saved by it.

An Economic View on Reinsurance
Preparing for Solvency II
Johannesburg, Feb. 2, 2007
Michel Dacorogna
Page 16

Conventionally, reinsurance premiums are perceived as isolated
costs related to the reduction of insurance risk. Accordingly,
recoveries and premiums should balance on the long run.

However, this view misses the fact that reinsurance is a substitute
for risk capital.

Risk capital is not for free. Investors expect an adequate return on
their investment. By substituting risk capital, reinsurance thus is
lowering capital costs.

The basic idea: Reinsurance should be structured to leverage
reinsurance premiums and capital costs optimally, which means
reinsurance should be structured to minimize the total cost of
capital and reinsurance.

Declining profitability during the last few years
 What is the economic value of the written business?

Complex and not transparent reinsurance program
 What is the total risk on group level?
 How efficient is the reinsurance program?
 Is there a possibility to keep more risk on the balance sheet, is
it possible to make better use of the risk capital?

What is the expected solvency margin over the next four years if
premiums grow by 4% p.a.? Is this growth sustainable?

Cat business
 The volatility grew constantly over the past few years.

For a risk tolerance level of 1 %, reinsurance reduces the allocated risk
based capital from 100 to 60 Mio USD.

Is this worth the cost of reinsurance? The answer to this question
depends on the cost of capital…

First result: Given the current reinsurance structure and including capital

Second result: On group level and for all risk tolerance levels, the
reinsurance program is efficient. However, this is not the case for all firms…

Optimization of Cat reinsurance

Preparing for Solvency II

Page 24
The existing Cat cover was not performing satisfactory during the last
few years:

In years with low to moderate claim experience, the reinsurance
structure did not bring any or only partial relief.

In years with large claims (e.g. 1999, Lothar), the cover was not
sufficient.

Reinsurance costs are perceived as too high for this limited use.
Reinsurance strategy

Increase of priority and limit of cover.

For example: 200% xs 200% instead of 85% xs 125%.

Result: Lower reinsurance premiums and higher economical
value of reinsurance program.


The profitability of each layer depends on the retro-premium, the expected
recoveries and the cost of capital saved by the layer.

This in turns depends on the risk tolerance level (the lower the tolerance, the
higher is the RBC and the more RBC is saved by the retrocession).


The approach combines financial analysis and risk modeling and is in
line with the spirit of the new solvency regulations.

It is a quantitative tool that allows to assess the overall risk of an
insurance company.

It allows to assess the economic value of different strategies.

Thus, it helps design optimal risk mitigating strategies.

It needs good data and a fair amount of modeling efforts.
