Purpose of the Approach
8
•
Objective reinsurance pricing methodology based on
financial market theory to quantify the risk of writing a
public D&O reinsurance portfolio
•
Risk transfer mechanisms using reinsurance and
capital markets
•
Return on capital indication based on the proposed
pricing methodology
Proposed Methodology
ƒ(L) = ƒ(M, D, L, C), where
•
ƒ(L) – Distribution of D&O losses
•
•
M - Market Capitalization of the company
D – Frequency of law suits as a function of default rates, credit
spreads, volatility of the stock price and/or credit spreads,
regulatory investigations, prior M&A or IPO activity, number of
shareholders owning 5.0% or more of the outstanding stock
L – Loss as a function of the market cap
C – Correlation within and between sectors
•
•
9
Data and Assumptions
Market Capitalization
10
•
Independent exposure base that is publicly available
and easily verifiable
•
Objective exposure base not dependant on company
management
•
Reasonable and consistent relationship between
market cap and corresponding losses
Data and Assumptions
Frequency of Law Suits
The base number of law suits is generated using publicly
available credit ratings from Moody’s and S&P to represent
industry defaults.
The fundamental assumption is that each default corresponds to a
potential D&O law suit.
The base number will be increased using various parameters to
reflect additional law suits that are likely to be filed beyond the
number of defaults.
11
Data and Assumptions
Adjustments to the Frequency Parameter
•
Credit ratings are adjusted to reflect outlook of each security, and
minimum of adjusted ratings is selected.
•
Credit spreads indicate a credit rating for each company. Each
company’s credit rating is further down graded if the spread
implied credit rating is lower than the rating adjusted for the
outlook.
•
The volatility of the financial performance is measured using two
parameters:
–
–
•
12
volatility of the credit spreads
volatility of the stock price.
Based on the volatility index, a downgrade of adjusted credit
rating is recommended.
Data and Assumptions
Adjustments to the Frequency Parameter
Example: Comparison of stock price movement of IBM, LU, MSFT
against S&P 500 (all rebased to 100)

Data and Assumptions
Adjustments to the Frequency Parameter
•
If the company is under a regulatory investigation the credit rating
has to be adjusted downward to reflect the increased likelihood of
a law suit.
•
A downgrade of the credit rating is applied if there are institutional
investors owning more than 5.0% of the outstanding stock.
•
A downgrade of the credit rating is applied if there has been any
M&A activity or an Initial Public Offering during the past three years
by the company
As the adjusted credit rating decreases the corresponding default rate increases
(reflecting a higher probability of default, thus a higher number of law suits)
