  • The cloud-based SaaS solution supports complex fixed income strategies, diverse asset classes, and advanced accounting methodologies.
  • FIS democratizes enterprise-grade technology, enabling asset managers of all sizes to handle sophisticated investments without high costs or complexity.

  • Partnership highlights FIS’ expertise in supporting evolving investment strategies across the money lifecycle.

Integrity Viking Funds is modernizing its investment accounting operations by implementing FIS Investment Accounting Manager, a comprehensive SaaS platform designed to manage increasingly complex portfolios with precision and efficiency. As asset managers incorporate alternative assets, complex derivatives, and diverse fixed income instruments, legacy systems often fall short in providing the required sophistication without introducing prohibitive costs or operational burdens.

FIS Investment Accounting Manager addresses these challenges by offering exhaustive support for a wide range of investment types, asset classes, and accounting methodologies. The cloud-based solution enables quick integration with existing systems, supports new investment strategies as they emerge, and delivers high levels of automation to streamline workflows and ensure timely, accurate data availability.

Shelly Nahrstedt, Treasurer at Integrity Viking Funds said: “For years, we believed that firms of our size had to settle for less robust platforms that couldn't fully support the complexity of our fixed income strategies. FIS has changed that equation entirely. Their decades of industry expertise have led to them providing us with a solution which allows us to capture and automate every security type and amortization method our portfolio demands. We're no longer spending valuable time on manual corrections and workarounds, so we can finally focus on what matters most: delivering superior outcomes for our investors.”

The platform’s fully integrated tools enhance reporting capabilities, cut through operational complexity, and keep investor capital actively deployed. This modernization empowers Integrity Viking Funds to compete effectively on investment strategy rather than being limited by legacy system constraints.

"Asset managers are navigating increasingly complex investment strategies while facing heightened expectations for precision, transparency, and speed," said Matt Stauffer, Head of Back Office Solutions at FIS. "When firms can compete on strategy rather than being constrained by their systems, this is ultimately better for investors depending on accurate portfolio management."

This partnership underscores FIS’ ongoing commitment to making advanced financial technology accessible across organizations of varying sizes, supporting accurate portfolio management and stronger outcomes throughout the investment lifecycle.
