We observe a new wave of appeal for the
quantication of operational risk. For banks,
the enhanced capital requirements in
the upcoming Basel III regime incentivize
the exploration of capital optimization
potential through more granular and risk-
sensitive measurement approaches. One
of these opportunities is the move to (or
the renement of the existing) advanced
measurement approach (AMA) for
operational risk. The wave of developmentof a second generation of Advanced
Measurement Approach (AMA) models
happens despite the higher regulatory
scrutiny to approve such models given
their assessment of model shortcomings
in the last nancial crisis.
For insurance companies, current Solvency II
requirements likewise trigger the
development of internal operational risk
models. At rst sight, the less explicit
requirements of Solvency II regarding
methodology choice seems to be an
advantage, but the lack of insurance

industry benchmarks and regulatory rules
can cause lengthy and difcult-to-manage
approval processes.
The aim of this brochure is to give an
overview of the critical steps towards the
design, development and validation of an
internal operational risk quantication
methodology. Given our international
experience with numerous clients, we
have learned that most of them strivefor a light approach which combines
and integrates existing operational risk
framework elements in a robust modeling
framework and which doesnt create
excessive operational burden in servicing
and maintenance.
We are condent that this brochure
highlights the relevant issues and that it
will constitute a value proposition for the
development of an internal quantication
approach or at least a jump-start for a
thorough assessment of the respective
risk and rewards.

Lessons Learned and Trends
A very prominent observation and tendency we notice in the
market is the integration of the quantication model in the daily
risk management process. Contrary to a stand-alone element for
regulatory capital calculation, the model has a clear link to the
Risk and Control Assessments (RCAs) framework and to rm-
wide risk appetite & quantication models. A solid and integrated
RCA approach for identifying, collecting and processing bottom-up
Operational Risk Model Integrated in
the Overall Operational Risk Framework
risk and control information and allocation of results with similar
granularity is a cornerstone of operational risk quantication.
A continuous and circular risk management process links RCAs,
top-down scenario analysis and the quantication model (based
on expert inputs and loss data) as process elements. Such an
integrated RCA framework has been implemented by Ernst & Young
at many clients (see box Risk Convergence).
Risk Convergence: systematic integration
of corporate governance, risk management
and control functions.
The main focus is on harmonizing the
various elements in order to avoid
redundancies and to identify and close
gaps in coverage and management of key
risks. Risk convergence is implemented
on a cyclical basis and has the followingcomponents:

8 Ernst & Young Operational Risk: Quantication Models
Motivation
The initial step for the development of any kind of model is
the denition of the model scope and motivation. Beside the
implicit purpose of quantifying operational risks, it is important
to determine if the need arises from regulatory requirements(e.g. Basel II/III, Solvency II), or if the model development is
driven by internal requirements (e.g. Earnings at Risk E@R,
scenario analysis for risk appetite determination). This basic
scope denition is the rst step to develop key information for a
suitable design of the model, such as the appropriate quantiles of
measurement, the calculation frequency and eventual constraints
in the choice between different approaches.
Model Components
Thorough Operational Risk model building requires both an
overarching governance framework and a robust basis of
components, such as Risk and Control Assessments (RCAs)
and Business Environment and Internal Control Factors (BEICFs).
We will briey describe these elements, together with indications
on common issues and solutions.
2 Elements of a Sound Operational RiskQuantication Model
The model components are sorted according to inputs, calculations
(methodology and engine) and outputs.
Model Governance Framework
Model inputs, calculations and outputs are embedded in agovernance framework that denes all key elements for the sound
development, use and maintenance of the model together with
a description of how the model aids higher level calculations or
further models (e.g. aggregated capital charge across risk types,
E@R). This includes in particular:
Appropriate validation procedures at inception and ongoing
Monitoring changes in the company operational risk prole orin regulations
Roles and responsibilities, guidelines for model use and reporting

Data can be information on loss events experienced directly by
the company (internal data) as well as information on loss events
experienced by peer companies (external data). The information
required for appropriate integration in the operational risk model is
quite extensive and includes, for example, the denition of a dateconvention (e.g. settlement date), a clear description of the event,
the amounts involved and eventual link to previous transactions and
controls (e.g. several transactions resulting from the same event).
In particular for external events, guidelines for the selection/
ltering and scaling of data lead to the transparent treatment of
model inputs.
Data may be collected locally (e.g. at business division or subsidiary
level), but should converge in a central database where quality
checks are made.
Finally, information provided by means of loss data is not only
important for the quantication of operational risk, but delivers
fundamental inputs for qualitative risk management as well. The
denition of investigations and mitigation measures can only
be efcient if the quality of loss data information is reliable and
detailed, in particular for external loss events.
Limited internal data history Limited information on low-frequency, high-impact Limited descriptive information of loss events Unsystematic data collection/loss of information
Not available or inconsistent (e.g. different templates for each business division/no aggregated view)
Not conceived to be input into a quantitative model (e.g. no EL estimationfor each risk)
Outdated information, no ongoing updates foreseen
The usage of external databases or local data consortiums allows for an increase ofavailable data, in particular in the high-impact, low-frequency region
Structured and inclusive collection process of internal loss events, centrally storedin a relational database
RCAs/BEICFs framework based on a structured and centralized approach(e.g. Risk Convergence)
Regular involvement of risk type-specic subject matter experts for the assessmentof the impact of mitigation measures and forward-looking elements
Risk and Control Assessments (RCAs) and Business Environment
and Internal Control Factors (BEICFs) represent another source of
important inputs for the quantication model. RCAs/BEICFs deliver
information gained through monitoring of the companys business
and control experience (similar to loss events information). Theseelements extend the range of information to forward-looking
elements (e.g. trends in the industry, upcoming new risks).
Typical key information that can be obtained from a well-structured
RCAs/BEICFs framework includes:
A complete risk catalogue that can help to structure the lossdata analysis (LDA), in order to model the body of the overall
distribution of operational losses
A subset of the risks catalogue (e.g. 10%) can inform aboutpotential high severity losses (scenarios), which have to be
analyzed for tail distribution calibration
Common controls and triggers are strong indications of potentialrisk/scenario dependencies, which have to be considered for
appropriate model design
Leveraged use of such information within a quantication approach
is possible only if the RCAs/BEICFs framework is sound, centralized
(rm-wide approach) and regularly updated.

10 Ernst & Young Operational Risk: Quantication Models
The scenario component of an operational risk model is
predominantly determined by two steps: the denition of scenarios
and their calibration. For both of these tasks, an integration of
expert judgment for tailoring the scenarios to the companys
operational risk prole is a common approach. However, expertjudgment should only complement industry information instead of
totally replacing it. In particular, industry information on tail
distribution characteristics of common scenarios contains signicantly
more robust information than an often arbitrary expert calibration
at high severity quantiles. For example investment suitability and
external fraud event severity distributions are typically fat tailed,
technical systems and business disruption severity is usually thin
tailed (see EY STORM Tool).
The denition of scenarios should cover all potential high severity
risks and result in a longer-term invariant of the model. The tail
calibration of scenarios is pre-dominantly a mid-term invariant
(worst cases assessments should not change frequently);
however it requires at least a yearly review based on the current
business environment and new information.
Not fully transparent inclusion of expert judgment leads to untraceable process The calibration of scenarios is neither challenged nor validated appropriately.
Experts are not fully conscious of the impact of their judgment to the overall result
Model components are not clearly distinguished(no separation of inputs for body and tail distribution)
Independency assumptions are not supported by appropriate analysis High sensitivity to few model parameters
Guidelines describing in detail the scenarios calibration process(inputs, initial calibration and validation) The inclusion of expert judgment (deviation from pure data analysis) is well
documented and justiable. The impact on results in discussed in dedicated
workshops
Separation in Low Impact High Frequency (LIHF) and High Impact Low Frequency(HILF) data clusters, for respectively body and tail loss distribution calibration In depth analysis of dependencies (e.g. across risks) Trade-off between model granularity and sensitivity
The two most common modeling approaches are Loss Distribution
Approach (LDA) and Scenario Approach (SA). Usually, both
approaches are combined to build the overall operational risk
quantication model, however with different levels of relative
contribution across industries and specic companies (based onthe quality and quantity of loss data information). Given the nature
of operational risk, where the tail behavior is dominated by low-
frequency, large-impact events, pure SA approaches may be an
appropriate choice when justied (e.g. LDA information is marginal)
and if no specic regulatory requirement conicts with such a choice.
One of the most challenging steps in the model design is the denition
of a sound linkage of LDA and SA components. This ranges from
a simple sum to aggregation by simulation. Again, the analysis
leading to a specic method must be justiable and well-documented
(no key model assumption based on arbitrary decisions).
Accounting for diversication effects (e.g. across risk types) is one
of the principal added values in comparison to simple quantication
approaches (e.g. the basic indicator for banks under Basel II).
Diversication has to be modeled according to the companys
structure and granularity level of inputs/outputs.
Finally, the choice of the calculation engine (capability, vendor
models) must be consistent with the model requirements, in
particular in terms of required exibility for the ease of ongoing
adaptations and improvements, frequency of use, number of users
and their quantitative operational risk expertise.

11Ernst & Young Operational Risk: Quantication Models
What happens to the calculation results? This apparently trivial
question is probably the most important. Models only conceived for
regulatory compliance are often inefcient, because model outputs
are not leveraged by the risk management and the companys top
management and may also fail use test requirements.
It is very important to have a closed feedback loop, where model
outputs are brought back to the companys management attention
at different levels. There is a need for consistency between
granularity of the inputs-gathering process and the model outputs
ability to describe marginal contributions to the total result
(e.g. at business division, unit or local entity level). This is a key
requirement for targeted and cost-efcient risk mitigation planning
of available resources.
At top management level, scenario analysis and model results
can provide material information about strategic questions. The
choice of product offerings and markets should also be evaluated
based on key risk information, in order to be consistent with the
rms overall risk appetite at all times. In particular for banks and
insurance companies, since the publication of new regulations on
capital requirements (Basel III, Solvency II), the inclusion of risk
assessments (qualitative and quantitative) in strategic decision-
making processes are already on the top of the agenda (e.g. capital
optimization).
Results cannot be allocated to a risk or scenario owner, because the modeldelivers only aggregated gures. This limits the efciency of incentives setting.
No internal reporting of results (risk awareness) Limited/inconsistent aggregation with other risk types
Besides aggregated results, detailed information on marginal contributions mustbe part of the model outputs (according to the companies risk taxonomy) Integration of results in internal risk reports and regular presentation of results
to the management

13Ernst & Young Operational Risk: Quantication Models
Operational risk potentially exists in all activities and usually shows
its principal characteristic of very negative skewed and fat tailed
risk proles (i.e. the most dangerous type of risk for the companys
survival) in all market segments. Within the nancial services sector,
banks and insurance companies are usually affected by materialoperational risk exposure which may reach the same scale of other
risk types, such as market and credit risks, depending on the specic
business. For asset managers, in terms of direct risks, operational
risk is even the dominating risk type. For non-fnancial services
corporations, like energy trading or health care production,
operational risk is also a very important risk dimension, in particular
for risks that cant be fully insured.
Under the assumption that effective operational risk management
is built on both qualitative and quantitative management, the
quantication step always begins with the identication of the
principal risks types. Even if some common operational risk
categories are specic to the companys activity, many others are
shared across industries. For example, natural disasters and
business continuity or execution and delivery usually affect all

companies. This is an important element for leveraging on modeling
experience across application elds and compliance with existing or
up-coming regulations.
Despite the common nature of operational risks, the relativeimportance of each single category is often market-specic.
Regulations and market loss events dene trends that may
drive risk categories to the top of the list. For example, in the
banking and insurance industries we have seen the importance
of investment suitability (consumer protection) substantially
increasing during the past few years. Asset managers experience
new regulations (e.g. UCITS IV, AIFMD) impacting the perception
of legal & compliance risks and non-nancial services companies
are increasingly focusing on natural disasters scenarios.
In the following subsections of this chapter, we are going to
discuss in more detail the two markets currently mostly affected
by regulatory requirements for operational risk quantication:
banks and insurance companies.

Basel II Second Generation Models
During the past few years banks have gained experience of 1st
generation operational risk models that were developed in the
course of the publication of Basel II requirements. The advanced
measurement approach (AMA) was predominantly chosen by largebanks with experience in in-house model development.
1st generation models, however, experienced severe issues during
the 20082009 period, in particular in terms of stability and
transparency, which have often triggered regulatory sanctions. In
order to support the development of a more robust 2nd generation
of models, the Basel Committee on Banking Supervision published
several studies between 2009 and 20111. The requirements of the
2nd generation of models include, in particular, a more transparent
and traceable calibration process and a better approach for the
integration of RCAs/BEICFs into the model and even of the model
itself into the daily operational risk management process.
Basel III Consequences of the Overall Capital Requirements
Increase
Whilst large banks had already recognized the advantages and the
higher risk sensitivity of AMA versus the basic and standardized
approaches of Basel II, the publication of Basel III expectations
for total regulatory capital have also raised the interest in AMA
at mid-sized banks. In particular, mid-sized banks with a large
contribution of operational risk to the total regulatory capital (e.g.
with dominating private banking divisions) are now reevaluating
the costs-benets trade-off in light of gross income forecasts for
the coming years.

Solvency II Leverage on Banking Experience
The internal model approach under Solvency II also requires a
model-based quantication of operational risk for insurance and
re-insurance companies, which roughly aligns practices with large
and mid-sized banks. However, the existing guidelines are not asdetailed as those of AMA under Basel II. The increased degrees
of freedom in relation to the model development represent
only supercially an advantage. In addition to the difculties of
developing a robust model design without specic expectations,
the most prominent project risk is linked to the local approval of
the model by the regulator. Different regulators may have different
levels of expectation, for example by stressing more or less the
importance of specic model components.
The most pragmatic approach is to leverage on the banking
experience of AMA banking models, which already underwent the
market stress test in 20082009. Especially because regulators
are expected to provide consistent feedback while approving the
models for insurance companies and banks.
Nevertheless, insurance and re-insurance companies currently
recognize the potential of a model-based quantication of
operational risk, in particular derived from the potential benet
of diversication effects, which may be very signicant for the
typical company structure (e.g. several operating entities active
on different markets and with diversied product offerings).

17Ernst & Young Operational Risk: Quantication Models
A most natural leverage on lessons learned in relation to operational
risk quantication can be gained from experience with AMA Basel II
1st generation models. The analysis of trends in regulations, in the
market practice for model design, in structural requirements and
in the denition of overall operational risk governance frameworksin the banking industry during the past few years constitutes a
solid knowledge basis for the development of new operational
risk models. AMA candidate banks, insurance companies, asset
managers and even non-nancial corporations, should consider
such lessons learned in developing their own quantication models.
4 Lessons Learned & Trends
Regulations
We experience a consistent tendency for enhanced regulatoryrequirements, not only for overall operational risk quantication
(e.g. Solvency II), but also for specic operational risk topics,
like misselling (e.g. MIFID II), which might impact worst case lossestimations for the respective scenarios.
Additionally, regulators raised their expectations for transparencyin model design, data ow and calibration. Internally developed
black boxes or vendor models with limited insight on the model
assumptions are not considered appropriate solutions anymore.
