THE BUSINESS APPLICATION
Where and how to use it
Use it to focus account monitoring, renewal reviews and top-up discussions. The business benefit is a consistent way to select accounts for attention while still distinguishing a temporary payment issue from a sustained change in behaviour.
Two borrowers are currently up to date. One has paid reliably; the other has repeatedly paid late before catching up. A behavioural review can expose that difference even when the current arrears bucket is identical.

DATA REQUIREMENTS
What records does it need?
These are the records your team would bring together for this analysis. The exact fields and history needed depend on your lending products, the question you want to answer and the period you want to assess.
| Record category | What it contains | Why the detail matters |
|---|---|---|
| Repayment schedule | Account ID, due dates and amounts, contractual changes. | Use the schedule that applied at each point in time. |
| Payment and balance history | Receipt dates, allocations, outstanding balances and arrears states. | Dated sequences are needed, not just a current snapshot. |
| Future outcomes | Subsequent arrears or default and observation end dates. | Use consistent review dates and outcome horizons. |
Past loan outcomes help assess how well an estimate reflects your borrowers. For a new decision, use only the information available at that time; later repayments help you review the result afterwards.
Understand data readiness →WHAT YOU RECEIVE
The output
Future-risk estimates, behavioural drivers and a prioritised basis for review. Prioritisation is subject to your operating policy.
WHAT TO WATCH
The limitations
Recent repayment history may be short or disrupted by restructures. Treatment effects and seasonal payment patterns must not be mistaken for universal risk signals.
FOR RISK & ANALYTICAL SPECIALISTSHow the analysis works+
The modelling approach
Lagged repayment features feed a calibrated classifier. Feature windows must end at the review date and outcome windows must follow it. Splitting records by borrower and time helps prevent the same history leaking into both model fitting and the independent performance check.
What your risk team should review
Borrower/time separation, feature availability, overlapping windows, calibration and stability by account age.
The right approach depends on your portfolio and available history. Review the fit to your borrowers, the reliability of the estimates and the effect of missing information before using the result in a lending decision.
