21.3 Editing Prepayment Rates in a Prepayment Model

Once the basic structure of the prepayment model has been created, prepayment rates can be added to, or modified for, each of the bucket values along the chosen dimensions. Use this procedure to add or edit annual prepayment rates in the prepayment model.

Procedure

  1. Search for the Prepayment Model, for which you want to define prepayment rates. For more information, see the Searching for Rules section.
  2. Select the check box next to the Prepayment Model and select the Edit icon.

    The Prepayment rate input page is displayed.

  3. Enter the Prepayment Rates in the Prepayment Model for the required dimensions.

    Node values for the row and column dimension are displayed as a table on the Prepayment rate input, while the node values for page dimension (if selected) are shown in the drop down list.

  4. Repeat the process for all node values of the page dimension. To change the node value along the page dimension, select the required node value from the drop-down list.

    Note:

    Node values will be displayed in the drop-down list only if you selected three dimensions. If prepayment rates are left blank for any of the dimensions, prepayment rates are assumed to be zero.

  5. Click Apply.

    The table with updated prepayment rates is saved.

  6. Click Save.

    All updates to the Prepayment Model are saved and the Prepayment Model summary page is displayed.
