Moody's Analytics has implemented enhancements to the AXIS actuarial system to address the modeling and reporting challenges of US GAAP Targeted Improvements. The AXIS system's liability modules have been significantly enhanced with new calculation and projection capabilities reflecting all the technical requirements of US GAAP. We also addressed the challenges of organizing, executing and extracting results from the multiple model runs needed to support current period reporting through the new US GAAP Link modules. These modules enable a smoother and more efficient reporting process, with optimized run time and output files, and improved governance and controls.
