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.

New feature highlights for version 2019b
  • Factor smoothing — You can now smooth factors across rows on exhibits, for example allowing you to account for erratic factors within in a triangle of age-to-age factors.
  • Seasonal averages — Arius now helps you understand and take seasonality into account as you make your factor selections. Arius provides this new type of average for use in the statistics section of exhibits in file structures with quarterly or semi-annual exposure periods.
  • External factor refresh — The system now retains the locations of the source XLSX files that provide industry and similar information for your exhibits. You can update your Arius file with new information whenever it’s available in the source file without having to remap and re-import the external data.

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

Notes:

  • This software will install and run only after you have accepted the Milliman License Agreement.

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.
