I) Introduction

II) The Elements of
An Integrated Framework
Copyright © 2003, SAS Institute Inc. All rights reserved.
At the most fundamental level managing operational risk involves
understanding ones risks and how to manage them
RISKS
What type
of risks
do I face?
Which are
the largest
risks?
CONTROLS
How well are
these risks
being
managed?
Managers need a set of tools to help them accurately
measure/assess their operational risks and
the quality of their corresponding internal controls

There are four fundamental steps to managing operational risk, with each
step leading to improvements in management & control quality and
greater economic profit
REPORTING
• Integrated MIS
reporting
MEASUREMENT
Economic Profit
• Estimation of cost of
operational failure
PROCESSES
• Loss data collection
FRAMEWORK
• Risk indicator data
collection
• Roles and
responsibilities
• Control selfassessment
• Policies and
procedures
• Risk assessment and
analysis
• Risk strategy,
tolerance
• Automatic notification
• Definition and
categorization
• Workflow
• Estimation of VaR –
risk capital
• Integration of Cost
and Risk measures
with CSA and risk
indicator scores
• Awareness of
exposures
• Understanding of
loss trends
• Improved risk
mitigation and
transfer strategy
• Cost benefit analysis
• Follow up action
Management & Control Quality

An integrated operational risk management program consist of five key
elements
 Internal and External Loss Data - actual loss events that have taken place
 Indicator Data - measurable variable that are believed to be correlated with
performance, losses, or loss variability
 Key performance indicators
 Loss (risk) indicators
 Exposure (scale) indicators
 Control Assessment Data - assessments based on pre-specified criteria
believed to be indicative of control quality
 Value at Risk Figures - monetary estimates of risk capital based on a quantitative
model
 Risk Assessment Figures - monetary estimates of risk capital based on
disciplined assessment process

What are the standards for defining and categorizing operational risk?
 Management information - Grouping of like items (homogenous risk types) to
facilitate the management of risk and assignment of controls on the basis of natural
boundaries
 Statistical Consistency - Mutually exclusive (uncorrelated) and exhaustive
(comprehensive), homogenous distributions
 Logical Consistency -
Copyright © 2003, SAS Institute Inc. All rights reserved.
Examples must be consistent with definitions
14
Event risk categories are represented in a three tier hierarchy

Internal Fraud
Losses due to acts of type intended to
defraud misappropriate property, or
circumvent regulations, the law or company
policy, excluding diversity/discrimination
events, which involve at least one internal
party
Secondary
Unauthorized Activities
Theft & Fraud
External Fraud
Theft & Fraud
Losses due to acts of type intended to
defraud misappropriate property, or
circumvent regulations, or the law by a third
party
Systems Security
Employment Practices and Workplace Safety
Employee Relations
Losses arising from acts inconsistent with
employment health or safety laws, or
agreements, from payment of personal injury
claims, or from diversity/discrimination
events.

IV) Collecting Loss Data
Copyright © 2003, SAS Institute Inc. All rights reserved.
Three sources of loss data may be considered
 Internal Data – data drawn directly from the entity whose risk is being measured; this
is the most relevant data set, but such data is generally insufficient for most modeling
and statistical analysis purposes because of the small sample size
 External Pooled Data
– public and non-public data drawn from a loss data sharing
consortium; this data is less relevant than internal data, but offers larger sample allowing
for more accurate modeling/statistical analysis
 External Public Data
– data drawn from public sources; less relevant than internal
data, contains a larger set of “tail events,”but subject to numerous biases – so cannot be
used directly for modeling.
While one would expect that consortium data will eventually
prove to be more useful than external public data,
this will only be true if these initiatives reach critical mass and
the data is honestly reported and consistently categorized
Copyright © 2003, SAS Institute Inc. All rights reserved.
19
A formal process for collecting loss event data must be implemented
Copyright © 2003, SAS Institute Inc. All rights reserved.
20
Loss data needs to be adjusted for inflation and scaled for size
Inflation adjustment:
$10 million loss in 1990 = $12.4 million loss in 2001
Scale Adjustment:
$10 million loss when a $2 billion (revenue) bank = $13.2 million loss when a $6 billion

A control assessment scorecard system must be relevant, consistent
and objective






Relevance - The control issues must be relevant to a business line and risk
Answer choices - The answer choices should be consistent
Weighting - The control issues must be weighted according to relevance
Scale - All scores must be converted to a consistent scale, e.g., 0 to 100
Normalization - The process for normalizing scores must be theoretically valid
Transparency - The process must be transparent to allow for buy in and to identify
opportunities for improvement
 Validation - Responses must be validated to avoid “gaming” the system
Copyright © 2003, SAS Institute Inc. All rights reserved.
24
Risk indicators must be validated through empirical analysis

In order for an indicator to be a true risk indicator, there must be
empirical evidence (from econometric analysis) supporting a
relationship between the indicator and loss frequency or loss severity

In July 1998, Nomura Securities International Inc, the US brokerage unit of Nomura Securities of Japan, reported that it had agreed to pay $47.9M in settlement of
charges stemming from the Orange County's bankruptcy lawsuit. The suit was filed against the firm for investing municipal county funds in high risk derivatives and
municipal bond trading that was illegal under California law. The Securities Exchange Commission reported that Nomura was one of the brokerage firms responsible for
the county's bankruptcy. Orange County claimed to have lost $1.64 billion. The SEC stated that Nomura had lent the county huge sums of money, which it reinvested in
search of high returns. Nomura also supplied the risky securities favoured by then county Treasurer and Tax Collector Robert L. Citron that plunged in value when interest
rates rose sharply in 1994. The SEC also charged the firm for its role in underwriting key bonds for the county and accused Citron of illegally investing in volatile securities
that were unsuitable for public funds.

In November 1998, ABN Amro Holding NV, a Netherlands full services bank and Europe's eighth largest banking firm, reported that it had realized a loss of 174M guilders
($141M) due to forgery, embezzlement and fraud perpetrated by four of its former employees. The four allegedly committed about 600 fraudulent transactions, making
improper use of about 30 client accounts. The bank said that after uncovering the irregularities, it fired the employees and notified law enforcement officials in February,
1997. The transactions took place within the bank's trust department, whose functions included maintaining bank accounts for 600 to 800 clients living abroad. Its products
included numbered bank accounts for clients whose identities were known only within the department. Employees also executed orders solely on the basis of telephone
instructions. The bank said that, upon inspection, some packages in custody that supposedly contained diamonds turned out to contain false diamonds, and diamond
shipment orders given by clients were sometimes accompanied by falsified invoices.

of dollars because of collusion among the firms between 1989 and 1994. This collusion caused an artificial widening of spreads, the gap between the purchase and selling
prices of stocks, thereby adding to dealer profits. The settlement also required the firms to improve trading policies and procedures. The case began in 1994, when the
SEC and the Justice Department accused major Nasdaq dealers of conspiring to fix the bid-ask spreads on stock quotes resulting in extra costs to ordinary investors on
their stock trades. Under the settlement, the brokerage firms with the most alleged violations agreed to pay higher fines. In making its original case, the SEC charged that
major Nasdaq dealers harassed or refused to trade with others who tried to offer investors a better price for a stock.

due to computer fraud perpetrated by two employees over the past sixteen months. The bank has initiated a case against the two employees, who used a loophole in the
bank's computer system for currency derivatives. They entered unrealistic intermediary values, which the system failed to document and managed to realise the profits in
their derivative securities. The fraud was only discovered after the installation of an updated system, required under a new law, which eliminates the opportunity for such
manipulation.

In April 1998, Korea First Bank, a South Korean commercial bank with operations in the US, reported that it had agreed to pay $93M in settlement of a lawsuit that
charged it with wrongfully dishonoring its irrevocable letter of credits. The New York Appellate Court ruled in favour of CalEnergy Company Inc, a global energy company
that manages and owns an interest in over 5000 megawatts of power generation capability among various facilities in operation, construction and development worldwide.
Casecnan Water and Energy Company Inc, a subsidiary of Calenergy was executing a power project in the Philippines. Hanbo Corporation had been acting as the
turnkey contractor and guarantor for the Casecnan project.KFB's letter of credit was issued as financial security for the obligations of Hanbo. The contract with Hanbo
Corp. was terminated by Casecnan due to Hanbo's insolvency and other misperformance in the project, at which time Casecnan made an initial draw on the KFB letter of
credit securing Hanbo's performance under the contract. Furthermore, Casecnan had made three susbsequent draws on the letter of credit, all of which were opposed by
Hanbo and draws under the letter of credit were dishonoured by Korea First Bank.

In September 1999, Citibank, a US commercial bank with global operations and unit of Citigroup, reported that it had realized a loss of $30M due to credit fraud. The
firm's UK branch was one of 20 financial institutions operating in the Middle East which were the victims of fraud. Madhav Patel, an Indian businessman, allegedly
deceived the bank by using forged documents to secure letters of credit guaranteeing payment for bogus transactions. The alleged fraud came to light earlier this year
when Patel's British registered firm, Solo Industries, ran into financial difficulties in the Middle East. Patel, who ran several metal smelting businesses in Dubai, secured
letters of credit from the firm as well as other banks to guarantee payments on shipments of metal to the United Arab Emirates. Police believe the shipments were bogus
and the money was diverted elsewhere. Patel moved to London after his business collapsed in May. He has since disappeared.

In May 1997, Credit Suisse First Boston Corp., a US investment bank and unit of Credit Suisse Group, reported that it had agreed to pay $4M in a settlement with 33
former investment bankers in its municipal bond unit. The former employees claimed that the firm improperly refused to pay them annual bonuses when they were
terminated. CSFB took the unusual step of offering no bonuses to laid off municipal bond investment bankers after the firm shut its municipal unit in 1995, even though the
bankers had worked through 1994 and had generated profts for the company. At the same time, some bankers in the mortgage-backed securities unit were paid bonuses
despite a loss of about $40M at that unit.

endorsed checks used in an embezzlement scheme. Knight Publishing lost nearly $2M between 1985 and 1992 in a scheme run by Oren Johnson, a production
supervisor at the newspaper. Johnson admitted authorizing the company to issue checks to Graphic Image, a commercial printing firm, for supplies that were never
delivered. He split the money with two other men and all three pled guilty to mail fraud, money-laundering and conspiracy. Knight Publishing claimed Chase Manhattan
should not have honored the checks because the endorser's name did not match the name on the checks.

In November 1993, Phatra Thanakit, a Thailand brokerage firm, reported that it had agreed to pay 40M Bhat($1.6M) in fines as settlement of Securities Exchange of
Thailand (SET) charges alleging violations of trading rules. The fine was levied over the firm's role in a technical error during trading operations. The firm, one of the five
biggest brokers in the Thai stock market, was responsible for an error involving a sale order for 200 million shares in Ayudha Investment (AITCO) which had only 25
million shares outstanding. The firm said that one of its subbrokers placed a sell order for 2000 shares but a computer fault converted the order to 200 million shares. The
company tried to cancel the order about 20 minutes after the order was placed on SET's computerized board and notified the exchange of the technical error. However,
some 18 million shares, worth more than 2.3 billion baht, had already been matched with buying orders. The exchange called an emergency meeting at the end of the
day's trading and decided to void the transactions for the 18 million shares.

There are several data issues to address in modeling operational value
at risk
• Internal data is the most relevant source of information for measuring operation risk, but it
is generally insufficient
• Internal and external data come from fundamentally different distributions and therefore
cannot be merged directly
• All operational loss data is collected above a threshold level, making it difficult to estimate
parameters for modeling
• Operational loss data are not well represented by traditional two parameter severity
distributions, such as the Lognormal or Weibull. Kurtosis (in log terms) ranges from 3-7.
• External data comes from many institutions of varying sizes, with differing processes,
controls and cultures, that it amounts to nothing more that a “stew”
Copyright © 2003, SAS Institute Inc. All rights reserved.

How can external data be relevant to my bank?
• Size Bias – Larger institutions (and businesses) are likely to experience more losses than
smaller institutions. These institutions are also likely to suffer larger losses.
• Control Bias – Institutions with weak controls are more likely to be represented in the
database because they experience more losses. These institutions are also likely to suffer
more large losses than well controlled institutions.
• Institutional Culture Bias – More aggressive institutions (and businesses) are likely to
experience more losses than less aggressive institutions. These institutions are also likely
to suffer larger losses.
• Infrastructure/Technology Bias – Less technologically advanced institutions (and
businesses) are likely to experience more losses than more advanced institutions. These
institutions are also likely to suffer larger technology losses.
• Media Bias – Large losses more likely to be reported than small losses.
• Legal Environment Bias – The legal system in certain countries may lead to more frequent
and/or larger losses.

Determining the most appropriate frequency distribution
Frequency is assumed to follow a generalized Poisson Process:
• If Mean frequency = Variance => Poisson
• If Mean frequency > Variance => Binomial
• If Mean frequency < Variance => Negative Binomial (Mixed Poisson)

46
Determining the most appropriate severity distribution
Severity has been observed to have a Kurtosis (in log terms) in the range of 3-7. This
suggests that using a log normal distribution would understate VAR, whereas using a
Weibull distribution would overstate VAR.
Distribution fitting through MLE – Maximum Likelihood Estimation: A process for directly
estimating the density function which maximizes the likelihood (probability) of obtaining
what was observed:

Because all the large loss events are not likely to take place in the same year,
the total VaR shows a diversification effect
