Nearly every top financial services company under the sun relies on this company's data systems. SunGard's investment support systems are used by banks, stock exchanges, mutual funds, insurance companies, governments, and others for transaction processing, asset management, securities and commodities trading, and investment accounting. This business is part of SunGard's Financial Systems business segment. Its other primary segment, Public Sector & Education, provides software in such areas as human resources, financial management, land management, and student information to the K-12 education and public sector markets. SunGard split off its third segment, Availability Services, in 2014. Fidelity National Information Systems bought SunGard for $9.1 billion in 2015.
