Case Study: IFRS 9 Compliance Model Execution Time Reduced by 20%+ Through Enhanced Programming

Essential SAS model optimisation to generate significant internal efficiencies in IFRS 9-critical reporting.

Secure Trust IFRS9 crop


Serving almost 1.5 million customers and employing almost 1,000 staff, Secure Trust Bank (STB) plays a significant role in the banking industry. It provides banking solutions for individuals, as well as a commercial finance division to support its business customers.

The banking industry itself is heavily regulated, including IFRS 9. A range of new provisioning models have been implemented by STB to comply with the IFRS 9 standard required by the European Banking Authority (EBA).

Business issue

STB uses its SAS platform to generate month-end reports for all business lines, ensuring they remain compliant with the finance industry’s stringent IFRS 9 regulation. The models STB were using were time-consuming to run (sometimes taking up to five hours to complete), delaying the production of the final reports. The models were also extremely complex, making it challenging for them to be maintained in-house.

Underlying causes

The complexities of model maintenance and processing times were due to inefficient coding, including duplication of steps and little documentation to describe the processes. Additionally, with no process for version-control in place, there was no way to revert to a previous model in the case of any problem.


STB was keen to improve the efficiency of its existing models in order to reduce the time required to produce these essential reports. Additionally, they wanted models that their in-house team would be able to maintain and administrate themselves.

Having chosen Amadeus for previous successful SAS projects, STB chose Amadeus as their supplier of choice for this work.

Amadeus solution delivered

Amadeus focused on optimising two of the customer’s existing models. This involved stripping out duplicate coding to streamline the model itself, utilising best practice methods and introducing important commentary throughout. After completion of the projects, Amadeus also wrote comprehensive documentation for STB, outlining exactly what work had been completed.

Having successfully completed the initial motor finance project, STB then asked Amadeus to carry out the same process on their retail finance model, before moving on to Phase 2, further optimising each. Ultimately, these model modifications led to significant benefits for STB:

  • Processing times reduced by over 20%, enabling increased team efficiency in the production of future insights to meet IFRS 9 legislation
  • Comprehensive backups of past programming for reference in the face of unexpected situations or for disaster recovery
  • Simpler models and clear documentation to allow internal teams to be more self-supporting
  • Traceable actions to ensure full auditability of future amendments to the models.

As a future improvement to these models, STB is now considering a project to fully automate these models, enabling processing to occur outside of work hours. This would allow the customer to maximise efficiency during office hours. It would run jobs conditionally, based on the success of previous jobs, centralising management and simplifying maintenance
