Arius™ is Milliman's new Property & Casualty loss reserve analysis solution.
Arius is a complete solution for analyzing unpaid claims liabilities, combining our industry-leading stochastic modeling tools with a robust suite of deterministic reserving tools and methods.
Property & casualty actuaries now have the tools they need to really understand their business, all at their fingertips. The result is a more efficient analysis process, and a deeper understanding of the underlying insurance exposure, for more informed business decisions.
A rich modeling solution
Arius' simulation models provide:
The solution provides three different families of stochastic models for estimating distributions of total unpaid amounts. There are three different overdispersed Poisson bootstrap models (based on the various England & Verrall, Pinheiro et al., and Shapland papers) simulating based on either Paid or Incurred losses, a Mack bootstrap approach, and four Maximum Likelihood Estimator approaches (based on research and papers by Dr. Roger Hayne).
While all models simulate to ultimate, the system also provides the option of reporting based on a one-year time horizon, important for Solvency II reporting.
Get the bigger picture, with correlation
Actuaries and analysts rarely work with only one business segment. At some point, most analyses involve summarizing lines of business into group, division, or company totals. Arius helps streamline this process, simulating multiple lines together, taking into account the important effects of correlation on the totals.
Deterministic tools for a more efficient team,
Arius’ new deterministic reserving module provides hundreds of exhibits, methods, and management reports, making it easy to examine your existing data in many new ways.
A full range of actuarial reserving methods are available immediately upon entering data.
All exhibits and reports are customizable, to address virtually any specialized need, and the custom reports still retain Arius’ internal structure, providing reliability together with the enhanced efficiency.
Arius Works Like Actuaries Work
Efficient work flow and reliable processes are critical to meeting actuaries’ tight deadlines. To help with these demands, Arius’ work flow can be modified to support the approach of an individual analyst, or the process of an entire reserving department.
Consistency makes teams more efficient
Consistent use of standard and custom reports among users and throughout a department reduces review time and streamlines consolidation.
Reliability helps managers be more efficient
The system controls the flow of all information, so its calculations are extremely reliable. Results from one calculation instantly update all related parts of the analysis. All calculations are tested by Milliman’s team of software and actuarial professionals -- formulas that require review and testing in old spreadsheet models no longer need to be reviewed with Arius.
Extensibility when needed
Despite the system’s customizable nature, there may be times when calculations outside the system are necessary. Arius provides an application programming interface (an API) which allows the system to pass data back and forth with spreadsheets. Users can use Excel VBA/macros or Visual Basic to share data, factors, and selections between the systems, so that calculations in either system can take advantage of the other’s capabilities.
