    Name Enter a name.
    Description Enter a description for the rule.
    Folder Select a folder from the drop-down list
    Modelling Set Select a Modelling Set from the drop-down list
    Economic Scenario Rule Select an Economic Scenario Rule from the drop-down list.
    Transition Matrix Type (Transition Matrix Details) Select a transition matrix type from the drop-down list. The available options are:
    • Rating - If this option is selected, then the status of the Band Details will be Not Applicable.
    • Days Past Dues - If this option is selected, then the status of the Band Details will be Predefined.
    Transition Matrix Frequency (Transition Matrix Details) Select a transition matrix frequency from the drop-down list. The available options are:

    • Quarterly
    • Half Yearly
    • Annually
    Computation Basis (Transition Matrix Details) Select a computation basis from the drop-down list. The available options are:
    • Count Movement
    • Value Movement
    Transition Matrix Projection Cap (Transition Matrix Details) Enter a natural numeric value in this field to define the cap of the transition matrix projection.

    Note:

    Negative and decimal values are not supported in this field.
    Band Details (Transition Matrix Details) You can define the band details if the Transition Matrix Type is Days Past Dues.Select the arrow adjacent to the status to set the band details in the Transition Matrix Band Details window:
    1. Click the Add button to add a row(s) to the table. The rows 1 and 2 are already present and populated by default.

    3. Click Apply.
    4. Additionally, click the Delete icon to delete the configured data and reset the page to the default values.
