The new frontiers of data sharing
How alternative data prove to be decisive in formalizing unbanked population (the Water Scoring)
The use of Credit Bureau services in the Telco industry (the Italian case).

• Master Degree in Statistics and Post Graduate Master Degree in Finance Economics
• 25+ years of experience in Credit Risk Management and lending processes
• 20+ years spent in top tier organizations (CRIF, Accenture, Experian)
• Global exposure: Europe, Latin America, Middle East
• Supporting CRIF geographic expansion in Middle East and SEA since 2017
• Sparse digital processes• Credit scoring was the new
wave• Risk management focused on
the corporate sector
25 years in the same field and still enjoying it

Ultimate goal of credit scoring is to
predict the future behavior of borrowers and their capability to repay financial obligations?
• Commonly classified as ‘first person’ fraudsters: people who ask for credit with no intention to repay the debt
Never pay
Lazy payers
Financial distressed
• People used to mange their financials very carefully usually managing multiple exposures with different lenders
• People who encounter unexpected high expenses or reduction of cash inflows during the repayment plan period.
Credit Scoring is a
largely adopted risk management tool by lenders globally
![Page 5: The new frontiers of data sharing · CRIF R&D unit regularly conducts analysis to enhance risk management tools. Two different data sources used: • 8 years of water bills data •](https://reader034.fdocuments.in/reader034/viewer/2022050602/5fa99efdc5a95f311e572b47/html5/thumbnails/5.jpg)
Scoring is an objective measurement of the risk (or other phenomena) based on data
Processes based on the outcome of a scoring algorithm handle applications fairly i.e. ensure that decisions are not affected by the subjectivity of human beings.
Consistency
Recommended decisions based on score can be configured to be aligned to the lender risk appetite.
Highly flexible tool to respond to strategic risk management changesand to adapt to changing external environment
Control
Scoring models provide accurate long term forecast of risk parameters underlying credit risk management practices in a bank
Scores are powerful forward looking risk quantification measure to be used at all stages of the credit life cycle
Predictive
Scoring models enable high level of processes automation i.e. facilitate lender to make faster, better decisions at all stages of the credit life cycle
Increased processes efficiency enables improved staff productivity, cost reduction and customer satisfaction
Automation
Key
benefits from
the usage of
scoring in your
decision processes
Why lenders globally leverage scorecards to take credit decision

Increase accept rate
Turn account holders
into creditors
Development of POS financing
Impact on lending practiceThe reduction of information gap between lender and borrower is a key driver to boost credit volumes (in economy expansion phases) and to contain credit crunch (during liquidity crisis times)

What data can help risk assessment
What are the drivers which bring consumers to miss their payments
Stability Elements:• ‘Time at’ variables
Personality treats:• Honestly• Discipline• Responsibility • Social desirability
Traumatic events:• Job loss• Divorce
RiskDrivers Financial planning capabilities:
• Age• Debt burden ratio
Role of the data scientist is to seek, analyze and combine for all potential predictive information to reach the most accurate forecast of the counterparty likelihood to default
Credit Product type:• Secured vs Unsecured

Water Score
The problem statement
Is there any correlation between the consumer water bills data and credit risk?
How can these data be used to assess credit risk and affect lending process?
The business opportunity
Can ‘alternative’ data source help to assess counterparty risk whenever ‘traditional’ data sources are not available?
CRIF R&D unit regularly conducts analysis to enhance risk management tools.
Two different data sources used:
• 8 years of water bills data• Credit file payment performance in Eurisc®, the Italian Credit
Bureau
![Page 10: The new frontiers of data sharing · CRIF R&D unit regularly conducts analysis to enhance risk management tools. Two different data sources used: • 8 years of water bills data •](https://reader034.fdocuments.in/reader034/viewer/2022050602/5fa99efdc5a95f311e572b47/html5/thumbnails/10.jpg)
End of outcome window
Snapshots: Only bills data analysed for clients with NO credit history
8 years of bills data available to calculate predictive characteristics
12 months of performance data (Credit Bureau History) available to assess clients performance
Diagnostic reports can be provided
• To detect model accuracy• To take lending decisions
![Page 11: The new frontiers of data sharing · CRIF R&D unit regularly conducts analysis to enhance risk management tools. Two different data sources used: • 8 years of water bills data •](https://reader034.fdocuments.in/reader034/viewer/2022050602/5fa99efdc5a95f311e572b47/html5/thumbnails/11.jpg)

Firstly we created the data-mart with the water company clients who – as of ‘today’ – do have a credit history in the credit BureauThis is a pre-requisite to track the payment performance and classify counterparties as good or bad
Secondly we filtered the initial data-mart to fulfil the requirements to build the ‘use case’1. We excluded all counterparties WITH some credit
history before bills data are available2. We excluded counterparties with some Bureau
history before the selected outcome window
The rationale behind is that we want to replicate a scenario in which the
sample is representative of No Hit population, at the time of the credit evaluation

Step 4:
Reject Inference
Model creation
1. All variables were analysed to measure the degree of
correlation with risk (target variable) – Bivariate Analysis
2. A subset of candidate variables was identified based on risk correlation, business logic, proved data quality and
correlation among themselves – From Long to Short List
3. Statistically significant variables were selected and partial scores are derived for each possible value of the
model variable – Logistic Regression
4. We measured the accuracy of the model with the best
practice indicators (globally adopted) – Post Development Accuracy Measurement
![Page 15: The new frontiers of data sharing · CRIF R&D unit regularly conducts analysis to enhance risk management tools. Two different data sources used: • 8 years of water bills data •](https://reader034.fdocuments.in/reader034/viewer/2022050602/5fa99efdc5a95f311e572b47/html5/thumbnails/15.jpg)
Final ModelResults
• Average of days past due (last 4 quarters)
• Amount of bills settled
• Ratio between billed amounts not settled over the amounts settled
• Difference between days past due (last 6 months against previous 6 months)
• Area of residence
Bills data (amounts and payment behavior) in the last 12 months resulted to most significant
Key variables
![Page 16: The new frontiers of data sharing · CRIF R&D unit regularly conducts analysis to enhance risk management tools. Two different data sources used: • 8 years of water bills data •](https://reader034.fdocuments.in/reader034/viewer/2022050602/5fa99efdc5a95f311e572b47/html5/thumbnails/16.jpg)
Step 4:
Reject Inference
51% is the value of The Gini Index
Post Development Analysis
12.3% is bad rate for the lowest score decile
The lowest score decile is 25 times more risky than
the highest decile
The score can identify 60% of the total population
with a bad rate of half of the average
Almost 80% of the total population could take
benefit form water bills data sharing

Use case #1
• Accept and decline decisions: a better balance between increase in accept rates and loss reduction
Use case #2
• Debt Collection processes: lowest collection costs by better segmenting customer base using Credit Bureau Score

Key Takeaways
• Alternative data sources add value to predict risk – standalone of in conjunction with traditional data
• In the absence of Credit Bureau data Water Bills data can help financial inclusion
• Credit Bureau data add value to the Telco’s processes
• Telco’s and Financial Institutions can cooperate to grow their business
