What is Risk?
Copyright © SAS Inst itute Inc. A l l r ights reserved.
What is Risk?
• Risk is the potential for uncontrolled loss of something of value. Values (such as physical health, social status, emotional well-being, or financial wealth) can be gained or lost when taking risk resulting from a given action or inaction, foreseen or unforeseen (planned or not planned). Risk can also be defined as the intentional interaction with uncertainty. Uncertainty is a potential, unpredictable, and uncontrollable outcome; risk is an aspect of action taken in spite of uncertainty. Wikipedia

Credit Risk – Overview
• Credit risk refers to the risk that a borrower will fail to meet their contractual
obligations and hence, will not be able to repay their loan
• Credit risk arises whenever a bank is expecting to use future cash flow to
pay a current debt
• In order to not jeopardise the financial situation of the bank, bank needs to
have risk management function and whenever a borrower defaults, the bank
is required to set aside capital to handle unexpected credit losses
• Institutions use permitted by supervisors approaches to quantify their capital
requirement

Risk Management
Risk management is the identification, evaluation, and prioritization of risks (defined in ISO 31000 as the
effect of uncertainty on objectives) followed by coordinated and economical application of resources to
minimize, monitor, and control the probability or impact of unfortunate events or to maximize the realization of opportunities. Wikipedia

Independence of the control functionsEBA guidelines on internal
governance (GL44)
Definition of an independent control function (GL44: Section D, §24-6)
In order for the control function to be regarded as independent, the following conditions should be met:
a. its staff does not perform any tasks that fall within the scope of the activities the control function is
intended to monitor and control
b. the control function is organisationally separate from the activities it is assigned to monitor and
control;
c. the head of the control function is subordinate to a person who has no responsibility for managing
the activities the control function monitors and controls. The head of the control function generally
should report directly to the management body and any relevant committees and should regularly
attend their meetings; and
d. the remuneration of the control function’s staff should not be linked to the performance of the
activities the control function monitors and controls, and not otherwise likely to compromise their
objectivity
Independence of the control functions are the backbone of the 3LOD structure

➢ Additional Tier 1 capital
to absorb losses; this should allow an institution to continue its activities and help prevent insolvency.
Going-concern capital
▪ Gone-concern capital: Tier 2 capital
would help ensure that depositors and senior creditors can be repaid if the institution fails.

Basel I (1998)
▪ set of minimal capital requirements for banks
▪ enforced by law in the Group of Ten (G-10) countries in 1992.
▪ Basel I primarily focused on credit risk. Assets of banks were classified and grouped in categories according to credit risk, carrying risk weights of zero (for example home country sovereign debt), ten, twenty, fifty, and up to one hundred percent (this category has, as an example, most corporate debt)
▪ Banks with international presence are/were required to hold capital equal to 8 % of the risk-weighted assets
▪ Most other countries, currently numbering over 100, have also adopted, at least in name, the principles prescribed under Basel I the efficiency with which they are enforced varies, even within nations of the Group of Ten
Copyright © SAS Inst itute Inc. A l l r ights reserved.
Basel I (1998)
▪ Risk weights
➢ OECD sovereigns: 0%
➢ OECD banks: 20%
➢ Residential mortgages: 50%
➢ Synthetic: 20% super-senior, 0% cash-collateralised mezzanine, deduction or 100% first loss (with national variations)
➢ Unfunded commitments under one year: 0%
➢ Unfunded commitments over one year: 50%
➢ Everything else: 100%
Sample capital calculation
▪ €100 million corporate exposure
▪ 100% risk weight = €100 million risk weighted assets (RWA)
Capital▪ Capital charge = = 8% minimum

Credit Risk Can Be Calculated Using Different Approaches
Standardised Approach
IRB Foundation
IRB Advanced
• Risk weights (0%-150%) is applied to different counterparts
➢ Depending on exposure class, external rating and maturity
• Risk can be mitigated using
➢ Guarantees
➢ Credit derivatives
➢ Netting
➢ Some financial collateral
Approach Comments
• Risk exposure amount is a function of PD, LGD, M and exposure (EAD)
• Dependent on exposure class and size of counterpart (FIRB not relevant for
Retail portfolio)
• Institutions that are permitted to use foundation IRB will use their own estimates
of the risk parameter PD, but using Supervisory estimates for estimating LGD
and EAD
• Institutions that are permitted to use advanced IRB will use their own estimates
for all risk parameters PD, LGD, M and exposure (EAD)
• For the Retail portfolio (household and small business) only advanced IRB
approach is available
• To be permitted to use IRB Approach more than 100 minimum requirements
must be fulfilled ( e.g. validation of internal risk model, use test, corporate
governance etc.)
Copyright © SAS Inst itute Inc. A l l r ights reserved.
• Yearly validation of rating/scoring and risk parameters
• Predictive power (out-of-time and out-of-sample data)
• Traffic lights etc….

IRB Approach more than
100 requirements must
be fulfilled ( e.g.
validation of internal risk
model, system reliability,
use test, corporate
governance etc.)
Copyright © SAS Inst itute Inc. A l l r ights reserved.
Methodology for Supervisors assessing Institutions on IRB ApproachKey focus points:
• Sound data quality
• IT systems used are safe, secure and reliable and the IT infrastructure is sufficiently robust
• The institution has to provide detailed documentation on the design and operational details of the rating
systems (RTS specify the minimum content of such documentation)
• Sound model validation and monitoring system in place (all rating systems should be equally verified
regardless whether they were built internally by the institution or obtained from third party vendor, including
understanding/ownership of calculations)
• IRB Approach goes beyond internal models and technical calculation of the own funds requirements, it defines
also the internal governance, including corporate culture and management of the institution
• The same data and parameters are used in the calculation of the own funds requirements, internal risk
management and decision making processes
• Collateral management, independence of the assignment of exposures to grades or pools, treatment of
multiple defaults and sufficient margin of conservatism
• Attention is drawn also to the application of human judgement at various stages of the development and use
of rating systems

Introduction
• Exposure classes are the basis for the calculation and reporting of capital
requirements.
• The principles for the calculation of minimum capital requirements for credit risk
in the Internal Rating Based (IRB) approach differ between the exposure
classes.
• It is important that the principles and processes for assigning exposure classes
are appropriate and consistent over time and across business units.
Each exposure shall be assigned to an exposure class
❑ Sovereigns
❑ Institutions
❑ Corporate (sub-classes)
❑ Retail (sub-classes)
❑ Equity
❑ Securitisation
❑ Other non obligation assets
Exposure Classes

EAD and CCF
What is Exposure?
• Exposure is the monetary amount at risk in the event of a
default
• Exposure can be divided into;
➢ Utilised exposure at the time of measurement→ Accounted for
on the on-balance sheet
➢ Unutilised exposure at the time of measurement→ Accounted
for on the off-balance sheet
• Unutilised exposure = Current limit of exposure – Utilised
exposure
What is Exposure at Default?
• The exposure at default (EAD) refers to the expected
exposure amount at the time of default
• EAD = current utilised exposure at the time of measurement
+ An estimation of how much more of the unutilised limit that
will be used at the time of default
Copyright © SAS Inst itute Inc. A l l r ights reserved.
EAD and CCF
What is the Credit Conversion Factor?
• When estimating how much of the unutilised exposure that will be used at the time of default, the
Credit Conversion Factor (CCF) is used to convert the unutilised amount to expected utilised
exposure.
• Since institutions are only required to hold capital for commitments that they have currently taken on,
CF’s shall be estimated for current commitments.
• The CF is a percentage measurement of how much of the undrawn credit line that will be used
between the time of measurement and the time of default → shall be set zero or higher.
• Since unutilised exposure can be found on the off-balance sheet the EAD formula can then be
expressed as below.
• In the SA and FIRB approach, the CCF´s are standardised and differentiated by exposure categories.
• In the AIRB and RIRB approach, an institution can use own CCF’s if permitted by the authorities.

EAD and CCFSA and FIRB: Categories
1. Unconditionally cancellable credit lines and revolving
purchased receivables → CCF = 0%
2. Short term letter of credit arising from the movement of
goods → CCF = 20%
3. Other credit lines, note issuance facilities and revolving
underwriting facilities → CCF = 75%
4. Other off-balance sheet exposures with full risk → CCF
= 100%
5. Other off-balance sheet exposures with medium-risk →
CCF = 50%
6. Other off-balance sheet exposures with medium/low-
risk → CCF = 20%
7. Other off-balance sheet exposures with low-risk →
CCF = 0%
Example
Full Risk:
❑ Guarantees having the character of credit substitute
❑ Credit derivatives
❑ Acceptances
❑ Asset sale and repurchase agreements
Medium risk
❑ guarantees not having the character of credit substitutes
❑ Warranties and indemnities
❑ Undrawn credit facilities with an original maturity of more
than one year
❑ Note issuance facilities (NIFs) and revolving underwriting
facilities (RUFs)
Medium/Low
❑ Documentary credits in which underlying shipment acts as
collateral and other self liquidating transactions
❑ Undrawn credit facilities with an original maturity of up to
and including one year
Low
❑ Undrawn credit facilities with certain cancellation features

Credit Risk MitigationWhat is Credit Risk Mitigation?
• CRM means “a technique used by a credit institution to reduce the credit risk associated with
an exposure or exposures which the credit institution continues to hold”.
• REA, Expected loss (EL) and large exposures (LE) can be reduced by the recognition of CRM.
• CRM can only be used if REA or EL is reduced.

Credit Risk Mitigation
Common Requirements for CRM Tools
❑ The credit institution must satisfy the regulator
that it has adequate risk management
processes to control those risks to which the
credit institution may be exposed as a result of
carrying out a credit risk mitigation practice.
❑ The credit protection arrangement is legally
binding in all relevant jurisdictions.
❑ In case of funded credit protection, the assets
relied upon should be sufficiently liquid and their
value stable over time.
❑ In the case of default, insolvency or bankruptcy
the institution should have the right to liquidate
or retain the asset in a timely fashion.
❑ The degree of correlation between the value of
the assets relied upon and the credit quality of
the obligor should not be unduly.
❑ The specific minimum requirements for the
CRM tool must be fulfilled.
Requirements for CRM Tools
• There are three types of requirements associated with CRM tools:
➢ Eligibility requirements: in general, collateral valuation guideline addresses the
eligibility criteria and the quantitative requirements
➢ Minimum requirements: are checked in the credit process
➢ Common requirements: applies to all CRM tools

AIRB
• For the portfolios using Foundation IRB the following LGD estimates should be used
➢ Senior exposures without eligible collateral; 45%
➢ Subordinated exposures without eligible collateral; 75%
➢ Covered bonds may be assigned; 11.25%
➢ Senior purchased corporate receivables where an institution is not able to demonstrate
that its PDs estimates meet the minimum requirements; 45%

Effective Maturity (M)
What is Maturity?
• Maturity is defined as the period of time for which a financial instrument remains outstanding.
• Maturity can be calculated in 4 different ways
Original Maturity
• Calculated as End Date/Next cancellation date – Start Date
• Used to set risk weight in SA for some off-balance products, etc
Minimum Residual Maturity
• Calculated as End Date/Next cancellation date – Calculation Date.
Nominal Residual Maturity
• Calculated as End Date – Calculation Date
Effective Maturity
• Standardised Approach: N/A
• Foundation/Retail IRB: Set to 2.5 years (or 0.5 for repos).
• Advanced IRB: set between 1-5 years based on underlying cash flows for the exposure.
Copyright © SAS Inst itute Inc. A l l r ights reserved.
Correlation Factor (R)
What is the Correlation Factor?
• The correlation factor R is a measurement of how much a customer’s asset value
correlates with the asset value of other customers
Systematic and Idiosyncratic Factors
• The size of a customer’s earnings is a function of;
➢ Factors that affect all customers’ earnings – Systematic factors
➢ Factors that only affect a particular customer – Idiosyncratic factors
• The more affected a customer’s earnings, and consequently their ability to pay their debts,
is to systematic factors, the bigger the correlation is between their tendency to go into
default to other customers
• Since different kinds of customers are differently dependent of the systematic factors, the
calculation of the correlation factor differs between the exposure classes
Systematic Factors
❑ All systematic factors are treated as one single
factor in the IRB formula
❑ This single factor can be interpreted as the
global state of the economy
Idiosyncratic Factors
❑ Examples of customer specific factors are the
management’s skills and cost efficiency.
❑ Will tend to be cancelled out in a larger group
of customers

IRB Credit Risk – PDWhat is Probability of Default?
• Probability of Default (PD) is defined as the likelihood that a customer will go into default
over a one year period.
• The PD is determined by estimating the repayment capacity of the customer.
• In order to use own estimates for PDs for specific portfolios, approval from the
supervisory authorities is required.
Two Approaches and PD Scales
• Two different approaches and PD scales are used to categorise customers into groups
that reflects their probability of default
➢ Scoring approach for the retail customers (RIRB/AIRB)
➢ Rating approach for the corporate and institutional customers (FIRB & AIRB)

IRB Credit Risk – PDWhat is the Definition of Default?
• A default is considered to have occured when either or both of the following have taken
place:
➢ The obligor is past due more than 90 days on any material credit obligation to the
institution. 90 days may be replaced by 180 days, subject to the national supervisors*
➢ The obligor is unlikely to pay its obligation to the institution, the parent undertaking or
any subsidiary
• For retail exposures, the institution may apply the default definition on an individual credit
facility rather than the total obligations of a borrower

IRB Credit Risk – PD
The PD Scales
• PD is based on customer specific
rating/scoring grades and reflects the
long term average default frequency
(ADF) in each grade/rating.
• The internal rating (corporates) and risk
(retail) scales consist of 18 grades
➢ Rating grades → A+ to F-
➢ Scoring grades → 6+ to 1-
➢ Defaulted customers are assigned to
one of the 3 grades that goes from 0+
to 0-
• The PD of an exposure shall be at least
0.03% and the PD for an obligor in
default shall be 100%.

Credit Risk Modeling and Decisioning Payment issues estimation (application and behavioral)
Application and behavioural scoring
• A scoring model contains 9-12 characteristics taking into account different aspects of customer behavior on allaccounts. The scoring model produces a risk score. Target could be different 30+/6m, 90+/12m
• The behaviour scorecard provides a score (single number), derived from relevant data, that is used to predict thelikelihood of customer being bad from a credit risk perspective
• The output from a scorecard is a risk score, which is transformed to the odds or probability of default via the PDalignment process
Copyright © SAS Inst itute Inc. A l l r ights reserved.
Trended variablesTrended credit data contributes to a credit score by helping to assessthe trajectory of credit behaviors, measuring the magnitude anddirection of a consumer’s credit health in the last three to 24 monthsof time. Trended credit data can provide up to a 20 percentimprovement in predictive performance

Undesirable behavioral impact on data
Rating assessment should be objective, but data shows that’s not always the case
Example – Threshold for “High-risk” customers (2+ and lower)
Behavior effect → – increase PD for all customers
– large impact on capital cost

Rating model development
▪ The models/frameworks are developed when needed:
▪ Unsatisfactory results in yearly validations, requests from business area or if the
performance of current model not is satisfactory, requirement from FSA.
▪ Rating model development methodologies:
▪ Empirical: Default data is used for statistical modeling, requires many default observations.
▪ Benchmarking: Used when the number of defaults in the data is insufficient, so that external ratings
(e.g. S&P) have to be used as a performance measure in the rating model development
▪ Expert: Main input from credit analysts (Experts). This method is used if there are insufficient data
to use the empirical rating model development and there is no external rating to use as benchmark.
(The cut between different methodologies is not always clear, if default data exists but not enough to
draw statistical conclusions e.g. Large Corporate Rating Model, a mixture of empirical and expert
based methods can be used)
▪ Time series of internal customer for the relevant portfolio. Historical default observations, financial
statements (incl. adjustments), data on the qualitative factors and other relevant factors; age of
company, payment remarks etc.
▪ CRR states that at least 5 years of data is needed for the PD estimates. Due to the recent financial
crises , the FSA sometimes require ~7 years of data to include the 2008 downturn.

PD Estimation
Average PD = +Average ADF Safety Margin
• In order to obtain rating and scoring scales that divide customers into rating grades that reflect their
probability of default over a one year period, models are created
• The models are based on internal historical data
• For each of the rating and risk grades, the following calculation shall be fullfilled
Why no downturn add-on for PD?
For CCF and LGD a downturn add-on is applied to make sure that the values reflect
downturn conditions, which is the scenario of concern. However, in the case of PD,
average PD is transformed in the IRB formula in a manner that takes downturn
conditions into account. Hence, no additional downturn add-on is needed.
• Safety margin is Margin of Conservatism which adds conservatism to the PD estimates
• The PD models are validated annually to secure that the equation above holds. If not, re-estimation of
the PD estimates is initiated.
Copyright © SAS Inst itute Inc. A l l r ights reserved.
IRB Credit Risk – PD: Rating Model DevelopmentFrom Model Input to Rating (using fictive figures)
• The factors and factor categories are given a statistically derived risk weight depending
on their correlation to the factor categories and ADF respectively. However, the customer
factor score is directly added to the accumulated FF and QF score.

IRB Credit Risk – PD: Rating Model DevelopmentSegmentation
• If different sub-segments of the model portfolio is expected to behave differently there
might be reason to have a model segmentation.
• Example of different types of segmentation:
➢ By industry
➢ By size
➢ By country
• Example of ways of segmenting the model
➢ Different factor value cut-offs (if a factor value is
expected to be associated with different risk levels
depending on segment)
➢ Inclusion of industry-specific factor in the
regression (e.g. country-specific macro-economic
factor, or Turnover as size factor)
➢ Different factor weights or different set of factors
(i.e. different models. If there are different risk
drivers between the segments.)
➢ Different mapping from scores to rating (same
model is applied, but the regression output is
mapped differently to the rating scale)

Observed Market trends - FinTech lending in US
• “…Their use of the latest technologies combined with cutting edge alternative and
trended data has likely helped them become leaders in the personal loan industry,” said
John Wirth, vice president of FinTech strategy and market development at TransUnion.
• “Counter to general assumptions about FinTechs, only around 10% of originated FinTech
loan balances are subprime, compared to 14% for the overall market for personal loans,”
added Wirth.
• At the end of 2016, FinTechs represented 30% of all personal loan balances, up from
about 4% in 2012 and less than 1% in 2010. This trend continued through the first six
months of 2017, with FinTechs now representing 32% of personal loan balances.

Mixing traditional and alternative dataThe correlation between the scorebased on the digital footprintvariables and the credit bureau scoreis approximately 10%. As aconsequence, the discriminatorypower of a model using both the creditbureau score and the digital footprintvariables significantly exceeds modelsthat only use the credit bureau score oronly use the digital footprint variables.This suggests that the digital footprintcomplements rather than substitutesfor credit bureau information and alender that uses information from bothsources (credit bureau score + digitalfootprint) can make superior lendingdecisions compared to lenders thatonly access one of the two sources ofinformation.

Machine Learning models
https://www.kdnuggets.com/2019/04/top-data-science-machine-learning-methods-2018-2019.html
Machine learning (ML) is the scientific study of algorithms and statistical models that computer systems use to perform a specific task without using explicit instructions, relying on patterns and inference instead. It is seen as a subset of artificial intelligence. Machine learning algorithms build a mathematical model based on sample data, known as "training data", in order to make predictions or decisions without being explicitly programmed to perform the task.

Ensure Risk models are of sufficient quality:
• all the aspects of the specification of the internal ratings and risk parameters, including the procedures for data
collection and data cleansing, the choices of the methodology and model structure, and the process for the
selection of the variables should be critically re-viewed,
• the adequacy of the implementation of internal ratings and risk parameters in IT systems and that grade and pool
definitions are consistently applied across departments and geo-graphic areas of the institution should be verified,
• the performance taking into account at least risk differentiation and quantification and the stability of the
internal ratings and risk parameters and the model specifications, and
• all changes related to internal ratings and risk parameters should be verified.
The validations must assess the accuracy and consistency of the model including its continued ability to adequately capture
the risk and uncertainty of the area it models. Historically, validating complex model was not deemed a high priority, and in-
house model validation teams lacked organizational and economic support.
Model development or recalibration can be driven by various reasons, including deterioration of existing models/model
systems. Issues around effort, complexity and turnaround time of validation process becoming more acute due to
advent of machine learning (ML) models.

Technology changes / Deployment / Maintenance
Data Scientists don’t stay for long (average tenure = 2.3 years^) and are difficult to replace (6+ weeks on average^^)
There have been 23 versions of R* and 39 versions of Python** since 2014
* Source: https://cran.r-project.org/** Source: https://www.python.org/downloads/
^Source: https://www.datasciencecentral.com/^^Source: https://www.forbes.com
This doesn’t include different versions of individual packages
• Requirements to recode in Java, Spark etc. for deployment add extra time and complexity
• Organizations take on responsibility for regression testing by using open source (most don’t realize that)
Copyright © SAS Inst itute Inc. A l l r ights reserved.
DATASETS
• Various shared drivers and/or desktop disk used to create, update and store datasets
• No dataset naming convention or users don’t always follow it
• No versioning rules for datasets or some manual emulation of versioning (quality and existence vary by user)
• No documented overview of datasets or manual documentation process (quality and existence vary by user)
• Some banks are using Git, VSS, etc. in modeling teams, but quality and usage vary by user
• Issues with performance (transferring big table loads network and reduced speed of execution)
• Hard to find required dataset
• Hard to track and understand purpose of datasets
• Hard to understand which data set is final and latest
• Low reuse of datasets, users create additional overlapping dataset loosing time and consuming even more disk space
• Multiple datasets containing same data and consuming extra disk space
• Low protection of final dataset form being overwritten/deleted
• Hard to transferee knowledge within team, onboard newcomers and/or when reorganization happen
• Issues with data access management
• IT does mostly technical maintenance
• Issues with audibility and compliance
Credit Risk ModelingTypical issues related to code based modeling
Copyright © SAS Inst itute Inc. A l l r ights reserved.
Credit Risk ModelingTypical issues related to code based modelingCODE AND VARIABLES
• Coding style, techniques and quality vary by users
• Various shared drivers and/or desktop disk used to store data preparation and modeling code
• No code file and variables naming convention or users don’t always follow it
• No variables dictionary or poorly maintained
• No documented overview of code files or manual documentation process (quality and existence vary by user)
• No versioning rules for code files and variables or some manual emulation of versioning (quality and existence vary by user)
• Some banks are using Git, VSS, etc. in modeling teams, but quality and usage vary by user
• When binning various continues variables “if – then” logic used through copy-paste
• Reuse is done through copy-paste of code files or its parts
• Data preparation and modeling speed significantly vary depending on coding skills of user – harder to plan and deliver, performance is
subject to volatility when experienced team member is replaced with newcomer
• Higher, broader and more specific requirements toward candidates (e.g. not only good statistics, but also strong programming, preferably
specific language) narrowing candidates pool, shifting up potential salaries, increasing recruitment time and key personal risk
• Issues with performance (non-efficient code will run longer, affecting performance of everyone if run on server)
• Hard to find required code file or/and code to derive variable
• Hard to track and understand purpose of code files
• Hard to understand which code file or code to create variable is final and latest
Copyright © SAS Inst itute Inc. A l l r ights reserved.
Credit Risk ModelingTypical issues related to code based modeling
• Hard to understand which code file or code to create variable is final and latest
• Different names for same variables and/or same names for different variables leading to wrong results and inconsistency
• Takes additional time to marry own and copy-pasted code
• Important data quality fixes and/or data transformations may be missed during copy-paste leading to mistakes
• Low reuse of important data quality fixes and/or data transformations
• Reuse of manually written code can lead to inherited mistakes
• Low reuse of code and previously created variables, users recreate variables and data preparation steps, where it may lead to different
definitions and differences due to operational mistakes
• High operational risk during copy-paste use, especially increasing for code maintained and reused overtime by several people
• 100+ lines code and multiple code files to create one output (e.g. LGD) hard and time consuming to update and maintain
• Hard to transferee knowledge within team, onboard newcomers and/or when reorganization happen – takes much longer to understand
what code does
• Typically new person to maintain code have to write it to match his own programming style
• Some code get lost on personal computers
• Low protection of final code form being overwritten/deleted
• Risk of using wrong code when promoting between development and production environment
• Issues with audibility and compliance
• IT does mostly technical maintenance

Typical rolesAuthorized persons Control activities (process step by step)
Sales team Verify authenticity of the documents, assures copies of the documents, is responsible for the data quality of application in CRM-system, verify that the
application comply with lending policies, forms an intermediate decision on application.
Fraud team Verify the feasibility of customer’s personal information, look up for customer on the black lists and lists of criminals, verifies employment, if necessary,
produces an interview with a client or visits the place of job or residence, also forms an interim decision on the credit application
Retail credit analysts
(underwriters)
Controls existence of interlocutory decisions, controls compliance with credit policies, examines the results of security-check, receives information on
customers credit history from the Credit History Bureau, makes judgment on the financial condition of applicant, analyzes fraud & social risk, verifies
income level and assess credit worseness of the customer, if necessary, requests additional documents, may require additional collateral, based on
the powers to act table determines level of authorized person who would make final conclusion.
Collateral valuation team For collateralized loans: verify announced value of the collateral, for mortgage loans, also checks appraisal report granted by independent approved
appraisal company.
Legal department
(mortgage only)
Review legal issues regarding collateral – there are a lot of legal restrictions in Russian law because of which collateral can not be recovered in case
of default (for example, when residents are minors) - so in some cases it is required to involve legal department into the process.
Decision maker Checks existence of all interlocutory decisions, goes behind conclusion of a credit analyst, studies information from the Credit History Bureau,
analyzes results of inspections, makes a decision and approves the final opinion on the application. The authorized person is acting within the
approved rules - a decision can not be made without a credit analyst, the amount approved by the loan must be at the limit of authority.
Back-office team Controls existence of approved decision, controls compliance of decision on the loan amount with the limits of powers of decision maker, checks the
completeness of client documents, prepares a set of credit documents for the client.
Signing person Controls presence of the approved decision protocol on the application, monitors the existence of interlocutory decisions and final conclusion, signs
loan documentation on behalf of the Bank.
Back-office team Controls the existence of signed decision protocol, controls the presence of signs of Bank and client on credit documents, forms internal transaction in
core banking (accounting) system.
Back-office supervisor Controls the existence of signed decision protocol, controls the presence of signs of Bank and client on credit documents, verify and accept internal
transaction in core banking (accounting) system.
Teller/ Cashier Transfer or allow money - documents must be signed by operator and supervisor, if cash is allowed, cashier also signs documents.

Typical Issues
#1 – Low level of decisioning automation and high human bias
#2 – Slow, IT resource consuming process to update “configurations” (e.g. scorecards)
#3 – Calculations (DTI, LTV, etc.) used in decisioning may be done outside of IT systems
#4 – Limited/No differentiation in processes between products, customer segments
#5 – High level of process duplications and unreasonable amount of 4eyes. Almost each delivery from
previous step is checked again
#6 – Poor data quality
#7 – Liner dependency between business growth and cost associated with origination

Credit Risk Modeling and Decisioning Best Practice Principles
#1 – Configurable balance between Cost per Decision, Time to Decision and Risk Appetite
#2 – Multi-step strategy based on value chain principle, data availability and logical flow
#3 – All decisions, which do not require human to human interaction and human judgment are moved into Decision engine from workflow
#4 – Decisions outside of Power of Acts are made by Decision engine, where humans provide judgments to be treated by standardized, agreed and approved strategy
#5 – Data acquired for decisioning on a needs basis through dedicated External calls to increase flexibility and decrease unnecessary data movement
#6 – Data aggregates required for existing customers are precalculated and loaded into dedicated Decision mart on a daily basis in batch
#7 – Intraday changes are acquired into Decision mart incremental based on triggers from source systems or based on schedule for further use in Decision engine
#8 – Decision strategy produces maximum possible assessment within minimum cost
#9 – Find best possible option for customer within acceptable Risk Appetite

Credit Risk Modeling and Decisioning Practicalities
• Decision strategy have to produce decision on 2 levels: decision on each applicant level and decision on overallapplication (where for example main applicant and overall application can be approved, but co-applicant can berejected, and main applicant may need to find another co-applicant, provide collateral, do nothing).
• Based on best practice principles Decision flow within decision strategy overall logically can be divided into atleast three stages:
• Analysis of customer’s application and existing internal customer data;
• Analysis of customer’s application and existing internal customer data plus automatically requested data from external sources;
• Analysis of customer’s application and existing internal customer data, data automatically requested from external sources aswell as manual verification results.
• Decision strategy should be executed fully in part of analysis of customer’s application and existing internalcustomer data before data request to external sources / assignment of manual verifications regardless ofwhether there are any single reasons for rejection of application / applicant. If result of one of decision nodesproduces automatic rejection, then all other calculations / decision nodes executions which happen before datarequest to external sources / assignment of manual verifications are undertaken to produce and save fullanalysis and history of application review and to collect all rejection reasons related to application / applicant toprovide them to front-office employee and further analytics.

Factors to consider include:
• Different customers will respond differently to actions
• Efficiency vary significantly across the types of actions available
(e.g: reminding sms versus outbound call on 5th day)
• The success rates vary significantly across the types of actions
performed (e.g. phoning is more effective than sending a
letter)
• The cost of collection may outweigh the potential return
• It is often combination of actions that make a particular
customer repay
The strategy needs to define:
• Customer type
• Most effective combination and order of actions

SME / Corporate lendingTypical challenges
#1 – Legacy Application Process
• Current credit approval system is rigid and inflexible. It does not allow an application to go back in process incrementally
• There are manual process done outside of the system
#2 - Extensive documents attached to the application which are largely untapped
• Information in attachments are not ingested and hence not leveraged for future consumption
• Rarely reviewed or used for subsequent account or limit reviews
#3 – Credit Assessment and Approval is manual and impacted by human biases
• The decisioning process is currently discretionary and there is no standardization of credit risk factors
• There is heavy reliance on the Credit Officer’s experience and judgement
#4 – Limited data availability and variety
• There is a lack of information for the Medium Enterprise segment
• As a result, the bank can only rely on traditional information point in time (e.g. financial statements) which are not forward looking

SAS SME / Corporate Risk Underwriting UIs: Credit Application Summary
Copyright © SAS Inst itute Inc. A l l r ights reserved.
A Customer Group is typically defined as a group of Borrowers (two or more individuals or legal
entities) who are in association with each other and who, if there is no evidence to the contrary, may
be regarded as a common risk because:
• One or several companies within a group own more than half of the shares in one or several
of the other companies within the group or, otherwise exerts decisive influence on one or
several companies within the group; or
• If, without being involved in a relationship as referred to in item a), their mutual connections
are such that one or all members of the group would presumably find it difficult to meet
payment obligations if one or several others of the group were to suffer financial hardship.
Following b) above a Customer Group exists e.g., where:
• Interdependency exists between two or more customers e.g. through co-operation
agreements and other agreements or inter-company debt
• The debtor is a co-debtor (directly or in the form of joint ownership, partnership etc.)
• The Borrowers are married, cohabitants or registered partners

The primary focus in credit analysis typically is to assess the risk for that the borrower may not fulfil its
debt obligation – the default risk.
As mentioned, if the customer is part of a customer group, it is important to evaluate how dependent
the customer is on the group in order to decide whether the analysis should focus on the group, parts
of the group, or only the customer itself.
Default risk is defined as the risk that the borrower may not fulfil its debt obligations. The assessment
typically is based on an analysis of the five risk components 1) country risk, 2) ownership and
management risk, 3) Industry risk, 4) company risk and 5) financial risk.
Furthermore, most banks evaluate if the commercial risk (industry- and company risk) is balanced with
an adequate financial strength. The higher the commercial risk, the lower the financial risk should be.
The analysis should lead to conclusions regarding repayment ability, financial flexibility and repayment
capacity. These conclusions should be aligned with the rating assessment. Factor typically used in
rating models include the last annual accounts as well as qualitative factors assessed, and customer
factors observed by the credit analysts at the time of the rating assessment.

SAS SME / Corporate Risk Underwriting UIs: Qualitative Assessment
Copyright © SAS Inst itute Inc. A l l r ights reserved.
The understanding of a customer’s ability to generate sufficient cash to cover both interest and debt
amortization is essential. The operating cash flow should be sufficient to cover the customer’s
obligations at any time. In addition, the customer’s financial strength or capacity in terms of equity is
considered. To be able to assess both the Repayment Ability and the Repayment Capacity of the
customer, it is important to have analyzed up-to-date financial information.
When performing financial analysis typically to enable consistent input of financial factors used to
calculate ratios (in order to comply with Banks definitions of financial ratios) that go into rating model
changes to the financial statements as reported by the company are required.
It is essential to understand and assess the ability to generate cash from ordinary recurring business
operations, excluding gains and losses from business operations that are based on projects or similar
activities. Under adverse business conditions Bank can only rely on the individual company’s ability to
generate cash from its operations. These might be affected by weak demand, but do not depend on a
few transactions in a market that might be illiquid for a prolonged economic downturn. Thus, it is
important to assess repayment ability not based on customer expectations, but also based on Banks
own forecasts of adverse market conditions, which will impact generated free cash flow and
subsequently ratios and rating.

Typically, the secondary focus is to assess Banks recovery position in the event of the customer’s inability to effect
payment. Recovery risk is defined as the risk that the collaterals and guarantees provided are insufficient to cover Banks
claim, in the event of the inability to effect payment. The assessment typically is based on an analysis of collaterals,
guarantees and documentation including credit structure and covenants. The conclusion includes the sufficiency of the
collaterals, guarantees and documentation established, in relation to Banks claim, in the event of the customer’s
inability to effect payment. Collaterals and guarantees should be regarded as “the second way out”, if the repayment
capacity becomes insufficient.
The importance of establishing financial covenants increases with the unsecured portion. The selection and level of
covenants should make it possible to react on early warning signals while the customer still is bankable or there is time
to take other action to mitigate the breach. Financial covenants should preferably be connected to the customer’s
repayment ability. Other covenants and clauses in the documentation could include cross default, cross collateral, cross
guarantees, cross acceleration, change of control, dividend restrictions, pari passu, capex restrictions, divestment
restrictions. These are typically established with the purpose to provide additional downside protection. SAS RM/CA UIs
enable Bank not only register collateral and covenant information, but also to spin-off separate process for proper
collateral valuation, including registration of various collateral value assessments, e.g. market value, forced-sale principle
based collateral value and etc.

• Seen as a negative action
• Only accounts ready to be lost should be decreased
• Only effective on medium utilised accounts
• Only high risk accounts should be targeted
• Only decrease delinquent accounts (2+ cycles)
• Consider use of decrease warnings at 1+ cycles
• Decrease should be done to a percentage of
outstanding balance
• Small open limit should be left to cover any charges
• Decrease actions should be matched with
collections actions

• Here we see the 2+ cycle, Low to High utilized accounts are further segmented by risk.
• Only the high risk accounts are decreased. It is best practice to reduce the limit to slightly above theoutstanding balance so that they do not become over limit. In this example the standard of 105% is used.
• Accounts with low to medium risk do not have their limits reduced. This is because this action can causeadverse reactions.

SAS Credit Risk Modeling and Decisioning Credit Limit Management – Profit-based Approach
• Develop an existing account profitability model, so that profitability is known for each account
• Define and calculate revenues / Define and calculate costs
• Can be analyzed by characteristics: Behaviour score, Utilisation %, Spend, Risk and etc.
• Marginally increase limits for good, profitable accounts in medium score ranges - Increase profitability
• Low risk customers
• Less likely to use the increased limit
• Low utilisation
• Increased limits will be utilised by the ‘bads’ within the higher score ranges
• Cap the top-end limits
• Allow usage by low-risk ‘goods’
• Restrict usage (bad debt) for low-risk ‘bads’

SAS Credit Risk Modeling and Decisioning Credit Limit Management – The challenge
• These models are combined to come up with the “ideal” additional line increase to offer to each account
• However, if you add up the “ideal” line amount for each account, the sum amounts to more exposurethan organization eager to issues due to capital, provisions and other costs constraints
• Therefore, the challenge is to come up with the most efficient way of reducing the overall exposure (andother measures) without giving up too much of the predicted NPV from the line
• Making account level line decisions with portfolio level constraints requires optimization

Risk Modeling and DecisioningEarly warnings
Copyright © SAS Inst itute Inc. A l l r ights reserved.
Early warningsBusiness approach
Key goal of early warning signals is to inform a bank about customer credit deterioration, so that a bank can
take actions lowering probability and volume of potential loss. Usually delivered as a reports, but requires an
extensive underlying foundation / infrastructure.
Data:
• Internal (industry analysis, media monitoring, trend in financial ratios, behavioral information, e.g.
corporate transactions, transfers; for households: salary amount, ATM transactions, merchant types)
• External (traditional, e.g. credit history bureau, government databases; non-traditional, e.g. telco,
social networks)
Ways to structure:
• Predictive models (EW models, PD models, EL models, Collection models, Attrition models, Fraud
models)
• Business rules (where models are not feasible for use and/or to compliment models)
Copyright © SAS Inst itute Inc. A l l r ights reserved.
Early warningsTechnical structure example
Copyright © SAS Inst itute Inc. A l l r ights reserved.
Early warningsTypical actions to take
Depending on previous customer relationship history, customer segment and reasons of credit
deterioration actions to be taken by bank significantly vary by type.
Typical set of actions include:
• Approaching customer to verify credit deterioration case and drivers of it
• Depending on the reason pushing either into debt collection or restructuring
• Actions towards exiting unused limits
• Proposing and discussing with a customer available options for restructuring
• Executing and monitoring post-restructuring situation

Incoherent customer view and misbalanced channel interactions
• Insufficient IT resources and infrastructure for robust model
implementation, execution and monitoring. High IT total cost of
ownership
• Solutions and models provided by external vendors are black boxes
and always require timely and expensive external involvement

Credit risk modeling - Data Gathering and ABT preparation
First phase of modeling project involves collecting and collating all datarelevant for a specific business task from disparate data sources andorganizing them. It includes merging and matching records for differentproducts, channels and systems in order to create a single customer view.
Within next step users write code / use GUI to read data and create dataset (“Analytics Base Table”) with which to develop specific model. Keytasks involved include:
• applying inclusion and exclusion conditions/filters to collected data,
• deriving and specifying “target variable(s)” – outcome model should
predict,
• specifying input variables to include for prediction power
exploration,
• deriving new input variables for prediction power exploration,
• specifying performance windows and sample windows,
• segmenting and sampling data.An
