1. Database

a. Triangle Groups with Uneven Sampling Periods can now be directly created.

Triangles can now be created which have mixed period sampling, for example Annual Accident periods and Quarterly Development / Calendar Periods.

b. Collapsing of triangles can now be done with a full range of uneven periods.

Monthly, Quarterly, Half-Yearly and Annual sampling periods can be combined in any combination as long as calendar period is equal to or a subdivision of accident period. Collapsing to a longer sampling period can be done with a full choice of different starting points.

c. Create New Triangle Group dialog has been simplified and extended.

The create new triangle group dialog is now more intuitive and is enhanced for uneven sampling periods. The dimensions of the new triangle group are also viewable before the triangle group has been created.

d. Triangle Groups Model Tab: Composite and Related buttons are now available for composite datasets to provide different ways into the MPTF framework.

e. Data imported from XML files can now be updated.

Entire Triangle Groups can be imported from XML files. If the data in the XML file has been updated including changes in existing triangles and addition of new triangles, these can now be incorporated into the database without affecting already existing models and scenarios.

f. Short cut keys for adding: Triangles, Exposures, Inflation and Premiums

g. Transferring Variables: Only variables that have values assigned are transferred when Triangle Groups are copied between databases

h. Query by selection from a menu: Clicking on the [+] symbol in Query view now brings up a menu of possible choices. (This was done in v10.1 by ctrl+double-click)

2. PSCF has been removed.

3. PTF

a. Accident Period Heteroscedascity modelling

Modelling of accident period heteroscedascity can now be done as an option in Manual Hetero.

b. Simulation dialog

Base variance and Accident period heteroscedasticity are additional options in the simulation dialog.

4. PTF and MPTF Interface

a. Forecast dialog has been enhanced

• First development period can be > 0
• Accident period variance can be changed
• Forecast units can be selected. The default Automatic option scales the units in the same way as 10.1
• Decimal points can be selected. This option will display decimal points if the forecasted value is less than 100 units.
• Future variance has been changed to Future Variance and Ratios with a corresponding base variance in order to simplify joint Accident periods and Development periods heteroscadisticity (variance) specification..

b. Load/Save model shortcuts

Ctrl+shift+L for load model; ctrl+shift+S for save model have been added.

c. Forecast Summary changes:

• % Errors was renamed % Differences
• Observed versus Mean Estimate tab added
  

  This tab displays the accident and calendar period totals for the observed and estimated values as calculated in the forecast table. These values are not displayed on the forecast table for Uneven Sampling Periods.

• Future Variance tables now display the variances by cell
• Loss ratios tab is only displayed when Premium data are associated with the dataset
• Incurred Losses Tab is only displayed when Incurred Loss data are associated with the dataset.

d. Reinstate Only alpha parameters

Added to right click menu on model and residual displays - reinstates all alpha parameters by setting the variances between periods to L and removes any alpha constraints.

e. NOTE: Saved forecast scenarios now include more comprehensive information about User Defined Variances.

Scenarios saved in 10.1 will still work in 10.2 but should be re-saved in 10.2 to ensure full compatibility.

f. The Reserve Forecast Table in the case of modelling data with uneven sampling periods no longer displays Calendar period aggregates (since they do not fit along the vertical axis of the table).

In this case the observed and fitted (mean) values are displayed in a new table "Observed versus mean Estimate" under Reserve Forecast Summaries.

5. MPTF

a. Optimisation within clusters

A setting to apply constraints only within clusters has been added to the MPTF modelling preferences.

b. Replicating parameters

Replication of parameters between clusters only has been added on the replicate parameters dropdown.

c. Outstanding Incurred Loss data

Outstanding Incurred data is automatically adjusted for Case Reserve Estimates if all Incurred Loss datasets have Case Reserve Estimates available.

d. Individual Forecasts can now be loaded for composite models.

e. Clear Hetero has been added to the MPTF dropdown

6. PALD / Reinsurance

a. Stoploss has been removed

b. Default display is now descending order

c. Additional quantiles 99.1-99.9, 99.995: The quantile table has been extended to include the quantiles from 99-99.9 in 0.1 increments and the value 99.995

d. PALD 'fixed seed' option has been added to the forecast dialog

e. 75th Percentile is now colored blue

f. PALD Value-at-Risk default changed: The default table now displays all quantiles down to 1% in descending order

g. Running ICRFS-Plus functions from other applications

Further methods have been added to the ICRFS-Plus COM Interfaces to further allow external applications to access ICRFS-Plus functionality.

7. Importing

Template Manager has been removed. Contact support@Insureware.com for COM Scripts to import your data.

8. Miscellaneous

a. All database passwords are automatically encrypted

Any database opened in 10.2 will have the username and password encrypted automatically. This means any database with a username and password will not be able to be opened in 10.1 without recreating the alias once the alias has used in 10.2 to open the database.
