PAS for Interest Rate Derivative Managers
The Principia Analytic System (PAS) is a proven, front-to-back platform for the independent valuation, risk management, and accounting of fixed income and derivative portfolios. Built to support the full lifecycle of interest rate instruments, PAS is used by leading buyside institutions to structure, value, and manage everything from vanilla swaps to complex derivatives with embedded optionality.
Flexible Access with pasVal
For firms that don't require the infrastructure of a full platform, our pasVal service delivers daily valuations, risk reporting, and hedge accounting through a streamlined, web-based interface. It's ideal for firms managing client books, performing independent valuations, or meeting audit and compliance demands without building out internal systems.
