New feature highlights for Arius version 2020c

January 2021 update: The January release of 2020c includes an update to a prior build of this same version. It addresses issues with interpolation and extrapolation functions in certain unique situations. See Installation notes for more information.

Interpolated historical and external factors – The system will now interpolate prior selections and external factors so they can display on exhibits in files with different data structures (e.g., annual industry factors can now be used in a file with quarterly development).

Enhanced cash flow reporting – Cash flow reports can now be more granular than the project files from which they are produced, for example quarterly cash flows from annual development. You can now automatically populate payment patterns using the new formula-driven payment pattern and extrapolation capabilities. And lastly, Arius cash flow reports now guarantee a full payout of all liabilities, even those persisting beyond the end of a completed payment pattern.

Show/hide Preview Pane – The new Preview Pane button toggles off the display of the collection view (the bottom right preview pane on the Arius desktop), providing quicker screen refresh by reducing the processing resources needed to keep the display of numerous large tables updated in real-time.

Stochastic table mapper – Arius Stochastic users can now apply the modeling tools to any properly-dimensioned input table rather than only the tables previously defined for the specific models. For example, you can now use the ODP Bootstrap model to project distributions using claims rather than paid loss data.

New feature highlights for Triangles on Demand

New ADX capabilities – ToD can now take advantage of Microsoft’s new Azure Data Explorer (ADX). ADX is a fast, fully managed data analytics service for large data sets. It provides significant performance improvements in processing and advanced querying, especially in data sets of a billion or more claim valuation records. Learn more about ADX here.

AEUploader – The AEUploader utility now automatically splits large CSV files into smaller components prior to their upload to ToD, improving the reliability of the uploading process.

Save Measurer Mappers – Arius and ToD users can now load and save ToD Measure Mappers to and from a file, making it easier to share these settings across Arius projects.

New feature highlights for Arius Enterprise

Project categories – Categories provide a very handy grouping tool to help sort and filter all your team’s projects.

Batch printing across projects – You can now export reports to PDF from multiple projects in one batch run.

Extract cash flow reports – Arius Enterprise now allows you to add cash flow reports to your Extract Tables List, to be extracted for further downstream reporting.

Direct Import supports triangles – Arius Enterprise can now use Direct Import to bring in triangular data, for example to import ultimate selections into the Historical Ultimates arrays in Arius.

New feature highlights for Arius version 2020b

Generalized Linear Model (GLM) — We added a new GLM reserving model in the Stochastic module. Modeling losses using a GLM framework has many benefits, including the ability to fit parameters along the calendar period dimension to account for calendar period trends, and to more completely tailor a stochastic model to the specifics of your data.

ODP Bootstrap Diagnostics — Also in the Stochastic module, we added new Actual vs. Expected tables with heat maps, hetero-adjusted Residual and Fitted Incremental triangles, and a new table of Fit Statistics for the ODP Bootstrap model. You will find all of these in the Paid and Incurred Loss Diagnostics folder in the Object Library. The Actual vs. Expected tables have also been added to the ODP Bootstrap Diagnostic collections.

Updated API examples – We updated API Example 4B to allow users to automatically update the structure of table named ranges to accommodate new diagonals. We also updated all API examples that use Excel user-defined functions to pull data from Arius to include a button to refresh the data from Arius.

We also fixed some minor bugs affecting both the Deterministic and Stochastic systems. A complete list of new features, other enhancements, and fixes is provided in the Installation Notes.

New feature highlights for Triangles on Demand

Secondary ToD databases — You can now load premium or exposure data (for example) into Arius projects along with claims data using the same queries, even though the underlying premium and claims data are stored at different granularities.

New feature highlights for Arius Enterprise

New back-end reporting capabilities — We added the ability to allocate reserve segment-level results to other levels of aggregation for reporting purposes (for example, allocate segment-level ultimates/IBNR/etc. to group, line of business, or branch level reporting). This new capability is also useful in performing such tasks as currency conversion and data reconciliation.

Notes:

  • This software will install and run only after you have accepted the Milliman License Agreement.
  • You may need administrator privileges on your computer in order to install Claim Variability Benchmarks.
  • A limited version is available at no charge during the installation process.

Quick start guide 

New feature highlights for CVB version 2.0

Benchmark loss development patterns (cvbLDFPatterns) – This function has been redesigned to include means and standard deviations instead of percentiles. In addition, 7 new data sets from Schedule P are now included (i.e., Paid, Incurred, Reported, Closed, CWP, CWOP, Incurred + IBNR).

Benchmark frequency patterns (cvbFreqPatterns) – This new function leverages all the Schedule P data to calculate 11 different frequency ratios for 10 x 11 arrays of all accident years by calendar year.

Benchmark severity patterns (cvbSevPatterns) – This new function leverages all of Schedule P data to calculate 6 severity ratios for 10 x 11 arrays of all accident years by calendar year.

Benchmark Unpaid distributions using Mack (cvbMackUnpaid) – This new function is like the cvbUnpaid function, except that it is based on the Mack and Merz-Wuthrich models instead of the ODP Bootstrap models and does NOT include any adjustment for model error to make it easier to calibrate the benchmarks to non-US data.

Mack means and Std Dev (cvbMackCalc) – This new function will estimate the Mack means and standard deviations for any size development triangle, including 8 different options to calibrate the function to your needs.

1-year time horizon means and Std Dev (cvbMerzWuthrichCalc) – This new function will estimate the Merz-Wuthrich 1-year time horizon means and standard deviations for any size development triangle, including 9 different options to calibrate the function to your needs.

Benchmark correlation between LOBs (cvbCorrelation) – This function has been expanded to include more data and new weighted averages based on premiums and premiums times one minus the P-Value.
