ONB Old National Bancorp

Old National Bancorp (“Old National”) and Axletree Solutions today announced an innovative collaboration whereby Axletree will host Old National Bank’s Swift architecture, providing a new level of highly-secure transaction messaging. This will ensure end-to-end control and complete transparency of banking transactions via Swift (Society for Worldwide Interbank Financial Telecommunication).

Axletree Solutions, a “Software as a Service” provider specializing in connectivity and integration, is Old National’s Swift Service Bureau, providing the bank with access to Swift without the internal burden and costs of managing the requisite Swift technology and infrastructure. Axletree also provides value-added services to Old National that include creating, enriching and transporting various Swift message types from legacy back-office systems with routing rules to achieve internal efficiencies and enhance revenue. Through Axletree, Old National also has access to track international payments in real time leveraging Swift APIs, for the benefit of its customers through an end-to-end secure environment.

“Our partnership with Axletree allows Old National to meet the technology needs of many of our financial institution and corporate customers,” said Joe Wicklander, President of Treasury Management, Merchant Services and Financial Institutions for Old National Bank. “Our clients continue to invest in automation to leverage their ERP systems, treasury workstations, and accounting platforms, and we thank Axletree for their commitment to providing innovative solutions that allow our clients to be even more successful.”

Swift provides a single secure channel rather than requiring multiple proprietary connections. Swift is a member-owned cooperative providing safe and secure financial transactions for funds and funds administrators, brokers and dealers, clearing firms and financial market infrastructures, payment processors, and asset and wealth managers.

Swift messaging supported by Old National will include Single Customer Credit Transfer, General Financial Institution Transfer, Bank to Bank Free Format Message, Confirmation of Debit, Confirmation of Credit, Customer Summary Statement Message, and Customer Detailed Statement Message. Swift connects multiple domestic and global institutions through a single, secure channel. Messaging capabilities include:

• Wire transfer payments and confirmations
• ACH payments and confirmations
• Prior-day and current-day information reporting in BAI2 format
• Integrated payable files in ISO 20022, CSV and EDI formats

“We are thrilled to partner with Old National Bank to improve its secure financial messaging experience via Swift,” said Jeff Ferguson, Director of Business Development for Axletree Solutions. “Through the use of our solution Symmetree by Axletree®, Axletree was able to help Old National Bank’s legacy systems create, translate and transport Swift-ready messages to facilitate its secure financial messaging needs. Axletree’s connection with Swift will also allow Old National customers to trace their cross-border Swift transactions in real-time. We thank Old National Bank for allowing us to show how Axletree provides its customers with ‘peace of mind.’”
