Banco de Chile Gains Competitive Advantage with Siebel CRM; Leading Chilean Bank Selects Siebel Solutions to Consolidate Business Processes and Provide Superior Customer Service.

SAN MATEO, Calif. -- Siebel Systems, Inc. (Nasdaq:SEBL), a leading provider of customer-facing solutions, has announced that Banco de Chile has selected Siebel customer relationship management (CRM) applications to consolidate its business processes onto a single branch platform and provide it with enhanced competitive advantage in the South American banking market. After going live with Siebel CRM, Banco de Chile expects to see an increase in profitability.

Founded in 1893, Banco de Chile is one of the largest and most profitable Chilean banks in terms of return on assets and shareholder equity. In 2002, Banco de Chile merged with Banco de A. Edwards, creating the second largest bank in Chile. In June 2005, Banco de Chile held a market share of total net loans of 18.1 percent, making it the largest holder of local capital.

The merger with Banco de A. Edwards brought with it a number of challenges, such as incompatible systems and a diverse customer base. The merger brought the bank into the mainstream retail banking world, and the existing processes for dealing with customers was unsustainable for such a large client base. To maintain its leadership position against stiff competition from international banks, Banco de Chile had to find a solution that could cope with large customer numbers but would also provide customers with the responsiveness they demanded.

Arturo Tagle, Senior Vice President of the Planning and Administration Division of Banco de Chile, explains, "We decided we needed one single banking platform and we knew we had to change the way we dealt with customers. Introducing CRM was a key element in this huge change management program. As well as being the leader in CRM, Siebel was selected because of the software's scalability and flexibility."

Banco de Chile selected Siebel CRM to provide an integrated multichannel distribution system for its retail and corporate banking systems. In addition, Banco de Chile sought to standardize processes within its call centers and to integrate customer relationship information with customer transaction information onto a single platform for its almost 200 branches across the country.

With Siebel CRM, the bank will leverage sales, marketing, and contact center capabilities to redesign the bank's processes in order to more consistently and effectively manage client relationships across all channels. The bank deployed Siebel CRM in its branches, call centers, and online operations for customer service, sales, and customer marketing. There are currently in excess of 3,500 Siebel users throughout the bank's branches, and more than 300 call center agents benefit from the software.

"As a result of introducing Siebel Call Center, Siebel Sales, and Siebel Marketing we expect to see an improvement in cross-selling and an increase in our customer base, as well as a better retention index," added Tagle.
