A significant challenge is to build a
“Superior ERM Solution” in partnership with the
C Suite whose “Characteristics” can be
benchmarked in terms of:
Dr Bob Mark
6
Characteristics of Policies at the
Core of Superior ERM Solutions
These
include:
The tolerance for risk (financial
and non financial) is integrated
and consistent with the
Business Strategies (and visa
versa)
Risk
measures are backtested,
authorities are expressed in
meaningful terms and reflect a
desired tolerance for risk
Independent
Superior ERM
Solutions
Risk
is properly disclosed (e.g.
Chinese walls may exist)
internally and externally on a
drill down and integrated
portfolio management * basis
Dr Bob Mark
7
Risk Disclosure
Key
characteristics of
disclosure include having the
ability to provide disclosures
such as:
Slicing
and dicing the risk in
real time (or near real time) by
risk type, asset class ,business,
product, industry, country, etc
mark-to-market
(mark- tomodel) vs. cash flow views
GAAP
Independent
Superior ERM
Solutions
vs. Economic view
Capital
(e.g. GAAP Capital vs.
Economic Capital vs. Basel
Capital)
the
main drivers of risk
Dr Bob Mark
8
Disclosing the main drivers of financial and non
financial risk would include answering such
questions as :

What are the top risks in the trading book and banking book
(i.e. a literal hit parade of risks)

Where are the concentrations of risk
(e.g. hot spots)

How often the list of main risks change

Have the forecasts of the top financial and operational risks (e.g.
stress tests) been predictive?

Have any of the top risks listed caused management to take
action to alter them in any way? If so, how?

What financial risks keep management up late at night?
Dr Bob Mark

Example 2: August 1998:
 Equity prices dropped sharply
 Equity Volatility increased
 Liquidity dried up
(Flight to quality)
August ‘98
High
Volatility
 Correlations broke down
 Credit spreads widened
 Credit quality deteriorated

become standard (e.g. market risk).Ultimately,similar
disclosure will become standard across all risk types

Characteristics of Methodologies at the
Core of Superior ERM Solutions

These include:

VaR and Stress Test
methodologies are predictive of
the actual losses and integrated
across all risks and all books of
business

Ongoing dedication toward first
class risk methodology
research

Mathematical models are
properly vetted.

Positions are properly valued
(and becomes a bigger deal
with SOX).

Risk methodologies are tied
into pricing and performance
measurement.

build a robust Risk Rating Process that enables you to calculate the PD,
LGD ,attribute capital and price credits

Dr Bob Mark

A term structure of risk is calculated over
multiple time periods
The term structure of PD’s (from the obligor
rating) and RR’s (from the facility rating ) is
typically applied to price as well as determine
the capital for credit risk

Example 8: A key characteristic of superior methodologies is
that they are used to price market, credit and operational risk.
For example, a Credit Derivative can be modeled as a put
l P = - N (- d

cumulative standard normal distribution, and

methodologies is that credit scoring analytics
can be supplemented with sophisticated analytics…..

Credit Score
The presumption underlying credit scoring models is that there exists a metric
that can divide good credits and bad credits into distinct distributions

Significant progress has been made in
measuring market risk and credit risk ….
with some early success at measuring
operational risk but…
having a a highly reliable unified measure of risk
inside of a common risk architecture is at the core
of superior ERM solutions

Valuation and Performance
Key
Characteristics
includes an ability to :

 accurately
vet and value
transactions (e.g. loan

 appropriately

flawed) quantify the

relationships of the
individual as well as
portfolio of transactions
