SunGard, one of the biggest providers of corporate treasury technology, is being acquired by Fidelity National Information Services, also known as FIS. The deal is causing some concern among companies that use SunGard's treasury products.

FIS provides banks with technologies and services related to customer and account management and payments. The company's announcement of the acquisition cited its interest in SunGard's products for banks in areas like trading and asset management, and emphasized the way these technologies complement FIS's product line. But the announcement made no mention of the products that SunGard sells to corporates. That led to questions about the extent of FIS's focus on SunGard's treasury products and whether it would continue to invest in them.

"You've got a company whose primary focus is financial institutions and the buy side, and here you have [SunGard] that does offer a corporate treasury solution," said Keith Bergman, international treasury accounting controller for Huawei Technologies, who is based in Amsterdam. "Personally I think there's a concern for those corporate customers that are using SunGard."
