Good Practice Risk Management
Looks at risk v. reward, not just at risk
Covers all risks
Not just those easily quantifiable: Enterprise Risk Management
Integrated
Common language for all types of risk: Economic Capital
Based on the possibility of economic loss
Economic, rather than Regulatory or Book Capital
Objective rather than expert based
Risk models
Heavy data requirement

Good Business and Risk Management Practice
In essence aligning a Bank’s capital with the
risk it currently incurs and more importantly
unexpectedly may occur

The Strategic Value of Risk
“….The typical belief is that risk management focuses on loss
avoidance. This view is based on the history of Risk management being
control focused.
However risk management has evolved rapidly to address the more
strategic issue of optimisation of return on risk. This evolution has
been accompanied by statistical, mathematical and financial
techniques….”
David Belmont in “Value Added Risk Management” (2004)

Basel 2: Best Practices in Risk Management
– Risk Management is a key success factor for a banking strategy
Current global banking environment demands best Risk Management practices to
withstand tough competitive pressures and public scrutiny
– Risk enhancements should be driven by a strategic vision, going beyond Basel 2
compliance:
– The alignment of the business model to the formal requirements
– The alignment of the organizational structure to the business model
– The alignment of the IT structure to the business model and the formal requirements
– Basel 2 is more than a set of regulations
it is a wholly different approach towards risk management, -measurement, -monitoring
and -reporting, formalising Best Practices

Basel 2 is more than complying with regulations
Within banks, it is highly important that Basel 2 not be
treated as a compliance exercise. It has to become part of
the management and governance of the bank with a greater
focus on risks an how those relate to the capital the bank is
holding.

Behavioural changes of Banks
Detailed data requests submitted to customers
Full disclosure (e.g. financial information on clients parent
company will be required)
Credit Portfolio Management : a ‘need to have’
Short term behaviour driven by rating
Credit derivatives market booming with AAA/AA rated banks
becoming the winners
Compulsory Ratings Disclosure
Standardisation pays off (i.e. program lending under retail
approach)
No more back up / liquidity facilities and other unused
commitments
Spread widening for high capital cost portfolios, spread
tightening for low capital cost portfolios
Less willingness of local operations in emerging markets to
buy government paper

Limitations and Advantages of Basel 1
“One size fits all”
causes mis-pricing of credit risk, distorted metrics
supervisors check compliance rather than risk management
false sense of security
Risk Asset Ratio static regardless of the economic cycle
inhibits efficient credit risk management process
No benefit for diversification, no penalty for concentration
No differentiation for duration
Promoted capital arbitrage
Advantage: Easy to set up and check

Basel 1 vs. Basel 2
Basel 1
Basel 2
•Finance content
•Quantitative
•Risk content
•Qualitative and Quantitative
•One standard for all
•Risk differentiation
Capital cost is determined by own estimates: a
bank’s history/track record determines its ultimate
capital cost
•Introduction of new asset classes (SL, SME)
•Introduction of a portfolio approach for retail assets
•Introduction of Operational Risk
•Three alternative approaches
•Three Pillars including all aspects of Risk Management
•Focus on Data
•Corporates – Banks – Sovereigns
•Exposure by exposure calculation
•Credit Risk & Market Risk
•One approach for all
•RWA calculation only
•Limited data use
Basel 1 = 33 pages
EU CRD > 500 pages + CEBS + regulator specific
The Basel regulatory capital formula for credit risk maintains the current definition of total capital and the
minimum 8% requirement:
RWA = EAD x PD x LGD x M

Basel 2 - Background
What is it?
A new Capital Adequacy Framework for the Financial System
A risk sensitive approach to capital allocation
A new methodology to assign economic capital on risk adjusted basis
dramatic impact (at profitability level) on the Banking Industry
changes the rules of the game one of the most significant raw materials “CAPITAL”

Basel 2 – Why ?
Needed to enhance the soundness and stability of the international
banking system (globalisation)
More risk sensitive capital requirements
Stronger risk management practices (quantitative and qualitative)
Enhanced supervision and transparency

Three Approaches to Credit Risk
Banks may utilise one or more of the following Basel 2 Approaches to calculate Credit Risk RWA
Standardised Approach
•Based on the existing Basel I
Framework
•Incorporate external ratings
Foundation Internal
Rating Based Approach
Advanced Internal
Rating Based Approach
•Based on internal ratings (e.g.
PD)
•Based on internal ratings
•Supervisor dictates many of
the risk weight elements (e.g.
LGD)
Lower sensitivity to Risk
•Use own estimates for many
of the risk weight elements.
High sensitivity to Risk
The key difference between the Basel 1 and the Basel 2 approaches to
the calculation of the Credit RWA is the inclusion of counterparty ratings

Credit Risk - Building Blocks
1. Probability of Default (PD)
The likelihood a debt instrument will default within 12 months
2. Exposure at Default (EAD)
Anticipated outstandings + ( (facility limit – anticipated outstandings) x Usage
Given Default %)
3. Loss Given Default (LGD)
Net Collateral Value”NCV”/Exposure at Default (EAD)
NCV = collateral value x recovery rate
4. Maturity (M)
Captures the higher/lower average risk of a credit with a tenor greater than one
year

Pillar 1 Credit Risk (FIRB & AIRB)
For our purposes, the main requirement arising from the Pillar 1 credit risk calculation
is that we can no longer derive Credit Risk RWA directly from the balance sheet.
Instead of fixed risk weights (0%, 20%, 50%, 100%) per chart of account line, the RWA
is now a continuous function.
RWA = f (PD, LGD, EAD, M)
PD per obligor is derived from the ratings infrastructure owned by Risk.
LGD is derived from risk ratings infrastructure, and in some cases from data about
credit risk mitigants (collateral, guarantees, netting, credit derivative protection)
EAD is dependent both on risk data (limits) and data about actual outstandings (as is
M).
EAD = f (Outstandings data, Risk data)
As a result we have to integrate data originating in the bank’s booking systems with
risk data.
The Pillar 2 control framework requires us to ensure that the data used to derive RWA
is consistent with the financial statements.
22

Other Basel 2 Related Requirements
A counterparty is only allowed to have one UCR bank wide.
All counterparties must be reviewed at least annually. Dependent on UCR
and credit committee decision the review frequency can increase.
Different counterparties belonging to one group can be assigned different
counterparty ratings, because each individual credit risk (customer), is rated
on its specific merit.
Guarantors must be rated separately.
We need to have 5 years of UCR-information.
We need to have 7 years of defaulted counterparty information.
The rating models used (both UCR and LGD) must be validated annually.

“Consistent quality data is the key to a
successful Basel 2 implementation”
31
© All rights reserved
Data Requirements
The amount and granularity of data has increased enormously since Basel 1
To calculate the Credit RWA under the IRB approaches we need granular data in the following
categories…...
SBU solvency adjustments)
2) Credit Approval Data e.g. Approved
Facilities, Internal Ratings assignment (UCR to Obligor/LGD
Class), GFID
Integrated 3) Credit Registration Data e.g.
Booked Facility, Usage Amounts, GID
Data Sets
4) Central Risk Inputs e.g Collateral
6) Results Data
1) Financial Data e.g. Outstandings, Cross-
Types, UCR relation to PD/ LGD Class to LGD %, Basel II
Specific (haircuts, CCF)
5) Standard Financial Data e.g.
Basel I codes (Risk weight % to COA), COA
7) Operational Data

Data Sourcing – Underlying Principles
Get close to the G/L for
asset data while
maintaining required
granularity
Criteria all source systems
must meet
As part of this strategy, the choice of source systems for Basel 2 data is underpinned by two key principles
Complete
Data should give complete coverage, including applicable adjustments
Strategic
Investment in data sourcing should take account of existing strategic
change programmes & re-use possibilities
Granular
Chosen source systems must be able to meet the low level of granularity
necessary for Basel 2
Reliable & Robust
Data must be from systems that are sufficiently maintained & supported
Controlled
Data must be from appropriately controlled sources (SarbOx & B2)
Timely
Data must be available and signed off, in an appropriate time window
Reconciled
Data must be from reconciled sources

Data Model
Describes what data (i.e. information) does the business need to
keep track of
Describes what processes does the business need to perform.
Describes entities, attributes, relationships
linked together (i.e. Process/Entity matrix) they form a Business
Model
34
© All rights reserved
Data Model
Provides a project with a consistent "language" set aligning it with
other users of the Model, both externally and internally
Starting point for construction of a Logical Data Model is
preferably (an industry) standard model
IBM's Banking Data Warehouse Model (BDWM)
Customisation of the Model is allowed assuming:
the essential terminology of the Model remains intact
customisation is controlled centrally to ensure consistent management information

ABN AMRO’s Basel 2 Approach
37
© All rights reserved
ABN AMRO Bank has chosen the Advanced Approach
Strategic aim to qualify for the advanced approaches as soon as possible:
Credit Risk - Advanced Internal Ratings Based (IRB)
Market Risk - Internal Models Approach
Operational Risk - Advanced Management Approach
Main reasons for this decision:
1. Advanced approaches are more sophisticated and risk sensitive -
gives lower capital requirements
2. Peer group/competitive positioning
3. Perception of the markets/rating agencies
