New feature highlights for Arius version 2023b

A new GetWeights function which allows you to reference method weights in user-defined tables from any of the system Comparison of Ultimates reports or other Formula Driven Assumptions input arrays.

The ability to create user-defined historical arrays to store other historical data and assumptions (e.g., BF Loss Ratios, Method Weights); important for Drivers of Change reports.

The ability to import factors into the Historical Factory Library; important for loading historical SDFs into a new project for Actual vs. Expected analysis.

New feature highlights for Triangles on Demand version 2023b

The triangle aggregation logic for cumulative measures has been modified. If a record is “missing” for a particular valuation date corresponding to a cell within a triangle, ToD will no longer reach back to the latest cumulative value and will instead treat the “missing” record as a zero. This enhancement helps correct those situations where claims closed without payments were “dropped,” but the last record showed nonzero case reserves.

To further restrict who can view data within a ToD database, a new Triangles on Demand permission was added for “Manage ToD Totals” and the “Load Data from ToD” permission now includes the action for “Create Segments” within Arius.

Installation notes

December 2022 update: The December release of 2022a is an update to a prior build of this same version. We fixed an issue wherein Arius Enterprise users were not able to check projects back into the database after they or another user has modified the user defined object library. We also fixed an issue when opening a user-defined resizable row array in Arius Enterprise if the table contained a formula and the setting for "Enable formula-driven payment pattern" was checked. See Installation Notes for more information.

New feature highlights for Arius version 2022a

The ability to easily select and highlight a diagonal on an exhibit (for example, to select all development factors for a specific diagonal/calendar period)

Search capabilities within the Object Library, so you can more easily find a specific table anywhere in the Library

An expanded set of system tables to help with IFRS 17 reporting

An enhanced “Diagonal” formula function now takes a scalar object as an additional parameter, with that scalar specifying the number of the diagonal that the function should retrieve (rather than having to specify the diagonal number directly in the user-defined formula)

Similar to Diagonal, an enhanced “GetPriorSDF” formula function takes a scalar object as an additional parameter specifying the number of the prior period from which to retrieve selected factors

New feature highlights for Arius Enterprise version 2022a

The ability to extract the weights vectors from Comparison of Ultimates reports or Formula Driven Assumptions into extract tables for use in additional reporting external to Arius

New feature highlights for Triangles on Demand version 2022a

Many new internal checks to assure that users cannot perform certain activities with a ToD database while other activities are taking place in the background. Examples include preventing users from adding or modifying records in a database while large deletions are taking place in that same database, and preventing users from deleting data sets or working with a database while its performance level is being scaled up or down.

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 2.1

Benchmark loss development patterns (cvbLDFPatterns) – New benchmarks for calendar year 2019 were added and all years combined were updated to include 2019 data. In addition, new benchmarks for all lines of business combined are now included.

Benchmark frequency patterns (cvbFreqPatterns) – For the 11 frequency ratio arrays, calendar year 2019 was added. In addition, new benchmarks for all years combined and all lines of business combined are now included.

Benchmark severity patterns (cvbSevPatterns) – For the 6 severity ratio arrays, calendar year 2019 was added. In addition, new benchmarks for all years combined and all lines of business combined are now included.

Benchmark correlation between LOBs (cvbCorrelation) – For all correlation benchmarks, new benchmarks for calendar year 2019 were added and all years combined were updated to include 2019 data.

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.
