Adopting a Top-Down Approach to Model Risk Governance to Optimize Digital Tra...Jacob Kosoff
Model risk management programs often began their journey by first creating a definition of a model. Then model risk groups would perform model risk activities on each item that met the definition of a model. These model risk activities include classifying risk, assessing current uses, evaluating ongoing monitoring results, validating conceptual soundness, testing model changes, and so forth. This approach was an important beginning for the field of model risk management as it helped identify existing models, discover fundamental errors in existing models, and prevent inappropriate use of models. However, model risk teams often focused only on processes that already include models and did not identify processes that would be significantly improved by using models. This results in model risk teams overlooking modeling capabilities that a process truly needs. However, model risk teams can go on the offensive and use their model inventory as a source of crucial business intelligence. Model risk teams can start to identify processes that do not include models and could recommend the use of existing models to improve those processes. Furthermore, model risk teams can reduce expenses at a bank by guarding against the development or purchase of models with redundant capabilities. Model risk management teams can ultimately be a champion for the extensibility and efficient use of models at an institution. The article was written by Jacob Kosoff, Aaron Bridgers, and Henry Lee.

Emerging Differentiators of a Successful Wealtlh Management PlatformCognizant
Changes in the wealth management industry are driving the need for a flexible, scalable platform that enables wealth managers to differentiate their services and profitably serve the mass affluent and mass markets.
Aptivaa is pleased to launch a series of blogs to apprise readers of some of the key aspects related mostly to Impairment Modeling, for compliance with the new accounting standards (IFRS 9), as well as to have a conversation with the readers about the challenges that banks are facing in their implementation efforts.
As the methodologies for IFRS 9 Implementation are still evolving, many banks are in the process of developing a roadmap towards implementation and are still evaluating methodologies that are likely to conform to the principles of proportionality and materiality. To this end, Banks being advised are to develop a Target Operating Model (TOM) design, which seeks to identify and document the work program required to meet IFRS 9 requirements on Impairment modelling and ECL estimation.
As the race against time to comply with IFRS 9 guidelines begins, several software solutions are being bandied about as a quick fix solution for automating the entire impairment modelling process. While automating is definitely the way to go in initiatives such as these, the question remains as to whether the software architecture should be of a strategic integrated nature or one that is decoupled and modular. In Aptivaa, we believe the answer to this lies in the 4Rs question: Readiness, Reflectiveness, Redundancy and Regularity.
This is the second post in the series of articles we have launched on various topics in the area of Asset Liability Management. Our prior post covered the recently issued Basel guidelines on Interest Rate Risk in the Banking Book (IRRBB).
A key aspect of the guidelines is the requirement for modeling of interest rate behavior of various balance sheet products. In this post we explore the nature of balance sheet cash flows, their key characteristics and sensitivity to market liquidity and interest rate movements. We also highlight how a deeper understanding of cash flow behavior is required to effectively manage the liquidity of the bank and also price balance sheet products. We focus particularly on the non-maturing deposits which form the single largest source of non-contractual cash flows of any bank.

Need Credit or Insurance?
Your Credit Score Helps Determine What You’ll Pay
Information about you and your credit experi-
ences, like your bill-paying history, the number
and type of accounts you have, whether you pay
your bills by the date they’re due, collection actions,
outstanding debt, and the age of your accounts, is
collected from your credit report. Using a statisti-
cal program, creditors compare this information to
the loan repayment history
of consumers with similar
profiles. For example, a
credit scoring system awards
points for each factor that
helps predict who is most
likely to repay a debt. A
total number of points — a credit score — helps
predict how creditworthy you are — how likely it is
that you will repay a loan and make the payments
when they’re due.
Some insurance companies also use credit re-
port information, along with other factors, to help
predict your likelihood of filing an insurance claim
and the amount of the claim. They may consider
these factors when they decide whether to grant
you insurance and the amount of the premium they
charge. The credit scores insurance companies use
sometimes are called “insurance scores” or “credit-
based insurance scores.”
July 2007
Ever wonder how a lender decides whether to grant you credit? For years, creditors have
been using credit scoring systems to determine if
you’d be a good risk for credit cards, auto loans,
and mortgages. These days, many more types of
businesses — including insurance companies and
phone companies — are using credit scores to decide
whether to approve you for a
loan or service and on what
terms. Auto and homeown-
ers insurance companies
are among the businesses
that are using credit scores
to help decide if you’d be a
good risk for insurance. A higher credit score means
you are likely less of a risk, and in turn, means you
will be more likely to get credit or insurance — or
pay less for it.
The Federal Trade Commission (FTC), the
nation’s consumer protection agency, wants you to
know how credit scoring works.
What is credit scoring?
Credit scoring is a system creditors use to help deter-
mine whether to give you credit. It also may be used
to help decide the terms you are offered or the rate
you will pay for the loan.

How a Predictive Analytics-based Framework Helps Reduce Bad Debts in Utilities WNS Global Services
The utilities industry has been riddled with payment delinquencies for the past several years, forcing utility companies to trade off profits for survival, and give up on their rightful revenue by taking the ‘write-off’ route. An ‘integrated three-pronged revenue protection strategy’ aids utility companies in effectively minimizing bad debt write-offs. Predictive analytics lays the foundation for this strategy by enabling customer segmentation, revising collections tactics and enhancing customer satisfaction interventions.

In contrast to the conventional approach that hinges on static variables and historical information, AI-based credit scoring harnesses the power of machine learning algorithms to scrutinize an extensive array of data from various sources.
An Analysis of Factors Influencing Customer Creditworthiness in the Banking S...Dr. Amarjeet Singh
This research is based on Bahraini bankers’ perception on the factors influencing customer creditworthiness in the banking sector of Kingdom of Bahrain. We consider that the research was done in the Kingdom of Bahrain which has a growing banking industry. To enhance the whole procedure of the creditworthiness, it is vital for an employer to understand the most important factors influencing customer creditworthiness. The purpose of the study was to investigate the factors influencing customers creditworthiness in the banking industry. The creditworthiness can be assessed through qualitative factors, quantitative factors and risk factors. The research was conducted through a survey, using the questionnaire as the research instrument. The respondents of the study are employees of banks across the Kingdom dealing with creditworthiness. The statistical tools used in the study are Multiple Regression Analyses and weighted mean. The researcher has found that there is significant relationship between all three factors and creditworthiness, and they don’t equally influence the creditworthiness. The research provides recommendations to banks in assessing the creditworthiness. The researcher recommended that employees must use the most effective methods such as credit scoring to conduct the analysis of creditworthiness in order to make effective decisions. Moreover, the researcher recommended that analysts should take into considerations the most effective factors in the analysis process and they must not neglect other.
In this presentation, Anup Singh domain leader of SME Finance domain at MicroSave highlights the key opportunities for the banks in enhancing access to finance to SMEs and also retaining customers through provision of non-financial services. Amongst other things, the focus is on use of automation to enhance efficiency in the processes of SME finance, lower origination cost and reduce turnaround time in expanding access to finance to SMEs.
It is hardly true that financial inclusion gaps forced countries around the world to explore the potential of digital financial services and fintech companies allow leapfrogging of traditional brick-and-mortar banking services. As per the study conducted by the World Bank, access to affordable financial services is critical for poverty reduction and economic growth. At the macro level, countries with deeper, more developed financial systems can allocate capital and risks more efficiently and consequently enjoy higher economic growth and larger reductions in poverty and income inequality. At the micro level, financial inclusions—access to and use of basic financial services—can reduce poverty, increase resilience and improve the lives of the poor. Digital financial services bridge the financial inclusion gaps and enhance economic growth. Fueled by the explosive growth of mobile phones, digital financial services (DFS) leverage technology to offer new forms of financial accounts that provide secure options for storing, transferring, and accumulating money. Hence, digital financial services are becoming accessible and affordable to all individuals and businesses through digital financial channels which ultimately boosts financial inclusion.
The contribution of digital financial service in alleviating constraints to financial access is quite immense. The emergence of mobile money, platform eco systems and open application programming interfaces (APIs) uplifted the digital financial service at the global level and impacted the level of financial inclusion. Yet in many emerging economies today, the majority of individuals and small businesses lack access to even basic savings and credit products, which hinders economic growth and perpetuates poverty. Financial exclusion is at the forefront in the list of the challenges which inhibit the growth of many economies around the globe.
Digital financial services enable financial institutions to provide convenient self-service saving and credit products. Traditional saving and lending processes are being replaced by quick and painless digital processes and helps to enhance digital customer centric experience.
Looking the relevance of digital financial service to financial inclusion, the government of Ethiopia is undertaking digital transformation to boost the economy and the necessary regulations have been crafted to create conducive environment. As per the study conducted by national bank of Ethiopia, only 35% of the population is financially included and the remaining 65% of the population is excluded from financial service. Needless to mention, digital financial services would allow financial institutions to outreach financially excluded segments of the population. Increasing digital adoption, digital payment offerings, ease of regulation to attract new entrants, and a growing fintech community are the main drivers of digital transformation in Ethiopia. As part of easing regulations, the government of

Credit review adds value to the underwriting
process by using data analytics and employing
key tests to determine underwriting performance
on automated and manual approvals.

Consumer lending is dominated by automation and analytics.
Lenders approve billions of dollars in consumer loans a year,
relying partly—and, in many cases, fully—on segmentation,
generic credit scores, custom credit scores, and other auto-
decisioning tools. For example, the majority of credit card
applications at major U.S. financial services firms are decided
without a human underwriter.
This article answers the following questions:
• How can credit review add value in examining the auto-
mated underwriting process in credit card, home equity,
and auto lending?
• How can credit review use data analytics to both supple-
ment and target manual transaction testing?
• How is the testing of origination scorecards by credit
review different from the model validation work of a
model risk management group?
How Credit-Scoring Models Are Developed and Used in the
Automated Environment
A credit review professional needs to understand the
objective of the custom score. Origination custom credit
scores are designed to rank-order credit applicants based
on a predefined metric, such as the probability the loan will
become 60 or more days past due within its first 24 months.
Once the score has been developed, the scorecard will
progress through the validation and monitoring process,
which includes a statistical validation prior to implementa-
tion. This validation will include, for example, how statisti-
cally powerful the custom score is by using the Kolmogorov-
Smirnov test for goodness-of-fit.
Understanding the objective of the scorecard and the
monitoring of its performance allows you to better determine
if it is being used as intended.

Loan-Decisioning Process
At most major financial institutions, consumer loan under-
writing involves an automated process in which applica-
tions flow through a detailed decision engine. A rule-based
underwriting tool, the decisioning engine usually contains
these multiple steps:
1. Segmentation / dual matrix.
2. Exclusions.
3. Credit policy.
4. Credit limit assignment.
5. Exceptions.
6. Pricing.
7. Final decision.
Segmentation / Dual Matrix
Segmentation by economic profitability (EP) is tradition-
ally the first step of any decisioning engine. Its objective is
to split loans into similarly profitable segments. Potential
customers are split by certain characteristics, such as the
length or depth of their bank relationship and by the amount
of revolving debt that would be correlated with higher or
lower EP.
After flowing through a decision tree, the potential cus-
tomer is assigned to a predefined bucket containing similarly
profitable applicants. Each bucket (or node, as it is called
in a modeling environment) has a scorecard assigned to it.
These scorecards are at the heart of the decisioning engine.
Usually, the scorecards are a dual matrix with a FICO score
on one axis and a custom origination credit score on another
axis. In cases where different nodes have very similar profit-
ability values, nodes often are aggregated into segments and
the scorecard is examined at the segment level.
In the simplified example below, the decisioning engine
segments applicants based only on the size of their deposit
relationship with the bank. In the example, deposit relation-
ships with the bank were found to have been an attribute
most correlated to economic profitability. Consequently,
when the decisioning engine was designed, this deposit
size attribute was selected for use in segmenting customers.
In the example, if the applicant has a deposit relation-
ship equal to or greater than $10,000, he or she would
flow to a more “lenient” dual matrix since the bank would
earn a higher economic profit for the loan. Similarly, if
the applicant has no deposit relationship or a deposit re-
lationship less than $10,000, the applicant would flow
to a more “strict” dual matrix. The values in the cells in
Matrix A and Matrix B represent the probability that the
loan would ever go 60 or more days past due within 24
months of origination.
In Matrix A and Matrix B, loans that land in the green
boxes move on the path to auto-approval, loans in the red
boxes move toward the path of auto-decline, and loans in
the yellow move toward the path of recommended approval.
Exclusions
Next, policies and procedures are layered on top using if/
then/else statements to automatically segment based on
certain characteristics, such as geography. In this exclu-
sion step, a decisioning engine usually includes numerous
modules with exclusions. Minimum borrower age and out-
of-market area are traditional exclusion flags that send the
applicant on a path to auto-decline. However, these vary
by financial institution and within financial institutions as
well as by product.
Credit Policy
Credit policy is coded into the automated decisioning system
and is the next checkpoint for all applications. Common
credit policy checkpoints include number of major deroga-
tories, length of credit history, and number of inquires in
the last nine months. If a credit policy flag is triggered, the
loan usually progresses to recommended decline.
Loan applications that land in
the green boxes move on the
path to auto-approval, loan
applications in the red boxes
move toward the path of auto-
decline, and loan applications in
the yellow move toward the path
of recommended approval.

Credit Limit Assignment
The next module assigns the terms of the loan. The credit
card example below indicates the credit card limit assignment.
Most financial institutions calculate between two and four
credit limits and use the lowest of the calculations. Credit
limit calculations fall into a few categories. In the approaches
below, the credit limit is a percentage of the borrower’s annual
gross income, rounded down to the nearest $500.
FICO/Income Approach to Credit Limit Assignments
In the FICO/income approach to credit limit assignments,
the credit limit is assigned based on the FICO score and
annual gross income. This example shows only nine cells,
but across financial institutions the number of cells ranges
from four to hundreds, especially when FICO is segmented
more narrowly by 10-point increments.
Ability-to-Pay Approach to Credit Limit Assignments
When using the ability-to-pay method, the first step is to
calculate the customer’s current debt-to-income (DTI) ratio.
With credit cards, income is stated and usually unverified.
The first step is to calculate the maximum credit that can
be granted that would prevent a new debt-to-income ratio
from exceeding internal policy—say, 40%. Therefore, if an
applicant currently earns $50,000 a year and his or her
existing debt is $15,000, the current DTI is 30%. Then,
using this ability-to- pay approach, a credit limit of $5,000
would be assigned, making the new DTI equal to 40%.
Credit Experience Approach to Credit Limit Assignments
The final approach in this example involves assessing credit
experience, which applies higher credit limits based on
credit experience.
In the previous examples, the bank would use the lowest
of the calculations, rounded down to the nearest $500.
Exceptions
The next module automatically checks for exceptions.
Warning flags appear for an application when there is a
Social Security number mismatch or when the application
is not in conformance with any of the following: deceased,
minimum income, and Patriot Act. If the application is on
the path to auto-approve after passing through all previous
modules but is flagged for an exception, the loan is put on
the path to recommended approval but it arrives on a hu-
man underwriter’s desk. The underwriter investigates these
exceptions (death, income, etc.) and makes an underwriting
decision to approve or decline the applicant.
Pricing
Economic profitability is again considered when loans flow
through the EP model. The model calculates an inter-
est rate that would generate a positive economic profit,
consequently charging a higher interest rate to applicants
who would require higher economic capital. The model-
produced rate is then rounded up to the nearest applicable
offered rate.
Final Decision
The result of each step is one of four options:
1. Auto-approved.
2. Auto-declined.
3. Recommended approve.
4. Recommended decline.
Recommended approve and recommended decline are, in

How Credit Review Differs from Model Risk Management
Credit review’s role differs from the role of the model risk
management group (sometimes called the model validation
group) in that credit review examines the adequacy,
effectiveness, and analytical rigor of the loan-decisioning
process, in addition to overall credit risk practices and
policies through periodic reviews, process reviews, and
continuous monitoring. Model risk management does not
review the overall loan decisioning process and credit
policies. It assesses the ability of the model to produce
accurate outcomes.
Credit Review Testing
Credit review adds value by examining both auto-decisioned
and manually approved loans. It assesses adequacy of the
examination and tests adherence to credit policies, practices,
and procedures. Credit review must examine the entire
underwriting process from credit scores and risk ratings
to final judgmental decisioning.
Data Requirements
To perform testing, credit review needs access to loan-level
origination and servicing data for each portfolio. It needs
to work with the relevant parties internally to ensure that
data is acquired and refreshed regularly. It also needs access
to up-to-date data dictionaries. Credit review works with
IT partners across the firm to ensure ability to connect its
tools (SAS, Tableau, etc.) directly to the dataset (Oracle,
SAS Data Marts, etc.).
Testing Methodology
Creditreviewcanuseseveraltestsandtestingmethodologies,
including:
1. Reviewing the automated underwriting process.
2. Reviewing soundness of assumptions and conclusions.
3. Using analytics to better target manual transaction testing.
4. Testing policy exceptions.
5.
Analyzing portfolio concentration trends to identify
emerging issues.
Review Automated Underwriting
Credit review’s first step is to review the automated under-
writing process. The purpose of the credit review testing is
to assess if the automated underwriting process is compliant
with existing policies and procedures within the line of
business (LOB). It is also designed to assess the adequacy
of policies and procedures within the LOB and to determine
if it performed sufficient data analytics to create or maintain
a current policy or procedures.
As part of this testing, credit review will look at each
variable in the auto-decisioning process. It will also evaluate
those loans that were inappropriately auto-approved. For
example, credit review might discover loans that have all
the necessary attributes to be auto-approved, but with one
exception: a current major derogatory in the credit bureau
file, indicating that the customer is 120 or more days late on
a different trade line. The customer still has a high enough
What Is Regression Analysis?
Regression analysis is a process used to estimate the relationships among variables.
In this context, it’s a technique for assessing the relationship between certain
credit characteristics of a borrower and the likelihood of that borrower defaulting.
A regression would estimate the correlation between a major derogatory in an
applicant’s credit file and a future loan default by assessing the performance of
hundreds of thousands of loans over a historical period. This result would allow
the reviewer to determine, for example, that a credit card applicant with a major
derogatory in the last 48 months is 20% more likely to become 30 days delinquent
on the card than would a similar applicant who did not have that major derogatory.

FICO and custom credit score to pass the specific thresholds;
however, the major derogatory flag in the decision engine
should have moved the applicant from auto-approve to a
manual decisioning process.
Credit review can challenge the adequacy and appro-
priateness of this process by using two testing methods.
The first testing method starts with a review of the overall
portfolio. To obtain this overview, credit review examines
a recent population of consumer loans. It can review any
portfolio (home equity, small business, unsecured lines of
credit, etc.) using these tools.
Assume the consumer credit card portfolio is reviewed
first. Credit review selects all applications within the past 24
months. It’s able to, for example, find the loans that triggered
a major derogatory flag but were still auto-decisioned. Once
credit review has found the issue, the next step is to assess the
severity of the issue. To do this, credit review must evaluate
the impact of the derogatory flag by comparing the share
of auto-approved applications having major derogatories to
the rest of the auto-approved population.
To further assess the importance of this major deroga-
tory flag, credit review can examine a variety of factors to
determine if customers with a major derogatory are per-
forming worse, the same, or better than similar customers,
assuming all other factors are equal. For example, credit
review can pull segments of loan populations and evaluate
the following metrics:
• Default rate on the credit card.
• Net present value (NPV) of the credit card.
• The EP of the credit card relative to the rest of the
population.
If it finds that the variable is not correlated to default, NPV,
or EP, credit review can assign a relatively low rating to the
credit risk issue. However, if credit review finds the variable
to be highly correlated to default, low NPV, or negative EP, it
could assign a relatively high rating to the credit risk issue.
Overall, the severity of auto-approving loan applicants
with a major derogatory, despite documentation stating
otherwise, would be based on numerous factors that credit
review can measure. This testing can be done using statistical
techniques such as regression analysis with tools available
from SAS, STATA, Excel, or others.
Credit review can further explore compensating controls
on these customers. Though they may be approved as fre-
quently and default more often, these customers may have
been granted a lower credit limit, which would reduce the
lender’s exposure to them. Credit review can simply find
the average credit limit of the target population versus a
similar population.
In a second testing method, credit review can examine a
targeted sample of credit bureau files. It manually reviews
these text files to determine if the applicants’ credit history
accurately reflects that they are currently 120 or more days
late on a trade line. If credit review still finds major deroga-
tories that are not flagged by the source system, it can report
to the internal client that the triggers are not populated
correctly and that the data flows need to be improved.
Credit review performs the analytical process described
in the step above to allow future transaction testing to be
more targeted, as it reviews the entire population analytically
prior to cracking open loan files for manual review.
Soundness of Assumptions and Conclusions
The soundness of assumptions can be similarly tested. Con-
sider the following example. Based on the requirements
of the automated-decisioning engine, if the credit card
applicant has $20,000 or more in outstanding revolving
credit, he or she would be required to have a minimum
FICO score of 720 to be auto-approved. If the applicant
has less than $20,000 in outstanding revolving credit, he
or she moves down the path of needing only a 700 score
to be auto-approved.
Outstanding revolving credit would be used to segment
loans into buckets of loans with similar EP because that vari-
able was found to be effective in parsing loans by EP. Credit
review can test the appropriateness of the $20,000 cutoff or,
at a minimum, require analysis of the splits by the LOB or
risk management.
Credit review can run an ordinary least squares (OLS)
regression on the population with, for example, EP or 90
days past due as the de-
pendent variables and
all credit metrics used
in the decisioning as the
independent variables.
If credit review finds the
variable for outstanding
revolving credit to be sta-
tistically insignificant, it
can recommend that
the client reestimate the
segmentation. While one
does not need to be a graduate-level statistician or have
advanced tools to perform this task, a credit reviewer would
need to be familiar with the regression tools within Microsoft
Excel and have a basic understanding of statistics.
Using Analytics to Target Manual Transaction Testing
After credit review has found how common and significant
certain risks are within a portfolio, it can use that infor-
mation to select a targeted sample for manual review. For
example, during the above tests, if credit review determines
that customers with $20,000 or more in outstanding revolv-
ing credit will default more frequently or are approved with

credit would be used to

more policy exceptions than similar customers, it can use
this variable—outstanding revolving credit—when filtering
the population in the process of selecting a sample to test.
Other variables correlated with default or policy excep-
tions—such as self-employment, those with less than $1,000
in deposits, or those applying online—also can be used as
filters in targeting the sample for manual transaction testing.
Policy Exceptions Testing
Credit review plays a major role in policy exceptions test-
ing. Imagine testing a credit card population of 500,000
approved and booked applications within a specified time
frame. The LOB reports that policy exceptions are rare—
about 5% of approved loans or 25,000 of booked loans.
Although in reality there are dozens of policy exceptions,
imagine, for the sake of simplicity, that there are just four
types:
1. The applicant has a debt-to-income ratio above policy.
2. The applicant is outside the allowable geography.
3. The applicant’s FICO score is below the cutoff for his or
her cohort.
4. The applicant has fewer than 18 months of credit history.
Credit review can look at the default rate, NPV, and EP
of loans approved with each of these exceptions relative to
the portion of the popula-
tion with otherwise similar
characteristics. Suppose
that, for three of the four
exceptions, credit review
finds that the loans booked
performed similarly to
their cohort in terms of
default rate, NPV, and EP.
For those three exceptions,
credit review will raise no new issues as those policy excep-
tions are not increasing portfolio credit risk.
However, assume that the fourth exception, FICO
scores below the cutoff, performs significantly worse than
a similar population across all delinquency and profit-
ability metrics. Using a data analytics tool to investigate,
credit review looks at the wealth management flag or the
deposit balance field, or the EP field, to determine if this
cohort has other compensating characteristics that offset
the higher delinquency rate.
When assessing the inherent credit risk, it is important
to determine what other actions occurred to decrease the
credit exposure. For example, does this population receive
a lower credit limit? Open the actual credit bureau reports
and other documents to search for information not visible in
your dataset. For example, are these customers more likely
to have longstanding, flawless credit histories in Canada that
were not included in U.S. credit bureau reports? Are they
more likely to have other profitable relationships with the
bank, such as IRAs, that compensate for the credit card risk?
By manually opening files with other relevant information,
credit review can more accurately determine the risk of
these policy exceptions relative to the overall population.
Remember, data analytics is not a substitute for manual
transaction testing. It’s a tool to supplement it.
Portfolio Concentration Trending Analysis to Identify
Emerging Issues
Credit review can search for portfolio concentrations in
the 500,000 population by using a data analytics tool like
Excel, Tableau, or QlikView. Are the loans concentrated
in one state? Are the customers’ employers concentrated
in one industry, such as natural gas? Do most customers
have more or less than $30,000 in revolving debt? Credit
review can plot this data over time and perform trending
analysis to determine if any of these concentrations are in-
creasing. Credit review also can perform a trending analysis
on a specific characteristic—say, the share of customers
booked via the Internet—and compare the delinquency
rate emerging from that booming channel relative to the
branch channel.
Conclusion
Credit review can increase its effectiveness in testing the
adherencetoandappropriatenessofpolicybysupplementing
traditional sampling with the use of data analytics. By
performing the analysis described in this article, credit
review will be able to more quickly and comprehensively
assess the entire portfolio, benefiting the line of business
and credit management.
Because of heightened regulatory scrutiny, resource and
budget constraints, and a need to augment the effectiveness
of sampling, this transformation is occurring within many
major financial institutions. As overall consumer lending
moves more toward data-driven decision making and less
toward judgmental underwriting, the transformation within
credit review is likely to keep pace with the transformation
within consumer underwriting.
Through its use of data analytics, credit review will im-
prove processes, broaden coverage, reduce resources need-
ed, decrease reliance on sampling, and produce more timely
and pertinent results. These processes will enhance credit
review’s ability to evaluate credit risk practices, ensuring that
they are consistent with an organization’s desired risk profile
and risk tolerance. The result is increased management ef-
fectiveness and, ultimately, enhanced shareholder value. v
