Project Overview

Ernst & Young (EY) offers a groundbreaking Effective Interest Rate (EIR) Calculator, tailored for the banking industry to streamline and enhance the accuracy of monthly financial reporting. Developed in collaboration with Atta Systems, this secure web platform seamlessly integrates with banks’ existing infrastructure and processes vast volumes of sensitive data, ensuring compliance and auditability. The calculator supports banks in efficiently managing extensive client portfolios, significantly improving operational efficiency and accuracy in financial reporting across leading financial institutions.

Context

EY experts developed a comprehensive methodology to take the necessary information and produce the monthly Interest Rate Calculator (EIR) reports. The solution proved hard to scale.  EY partnered with Atta Systems to develop a platform that automates the reporting task.

Challenges

While developing the Interest Rate Calculator, we had to overcome a series of challenges: 

Product Challenges

  1. User Experience Design: Creating an intuitive interface that simplifies complex financial data for bank personnel.
  2. Compliance and Security: Ensuring data integrity and meeting strict regulatory requirements for financial reporting and data security.
  3. Integration with Existing Systems: Integrating seamlessly with banks’ existing systems, including LDAP for authentication.

Technical Challenges

  1. Data Handling and Processing: Managing large volumes of data efficiently to maintain performance and responsiveness.
  2. Security Measures: Implementing strong security protocols to protect sensitive financial data.
  3. Testing and Quality Assurance: Conducting extensive testing to ensure accuracy in EIR calculations and system reliability, including stress and scenario testing.

Solution

We built a system that connects to a bank’s data sources, processes the required data, and produces the EIR reports: 5 aggregated reports for the whole client portfolio and several individual reports (for each client in the portfolio). Reports can be viewed online on the web platform or downloaded to usual exportable formats (CSV, xls). The system is designed to be deployed on a bank’s infrastructure and to leverage the existing data source and directory services (LDAP).

The proposed solution works as a web platform that helps the bank specialists run monthly effective interest rate calculations on their portfolio (for clients that contracted a credit with the bank).

Because EIR works with sensitive data, it is deployed within the bank premise, it is secure and all the steps that can be performed in the app are audited. To integrate easily with the bank system, we implemented LDAP so that bank personnel can log in with their credentials.
