4.12.2.2 Editing the Risk Element Weightings

You can edit the default weightings assigned to each risk element in the Reference Data Editor – Risk – Risk Element Weightings window. This reference data set specifies which fields in that record contribute to the risk score calculation for each type of record and to what degree (weightage).

The following steps explain how to view the risk element weightings for all watch lists:

1. Go to the EDQ URL and open the Director menu. The Director Landing page is displayed.

2. In the Director Landing page, expand the Watch list Management project in the Project Browser pane.

3. Expand the Reference Data node.
4. Right-click Risk- Risk Element Weightings and select Edit data.

   The format for the value in the RecordType column is the watch list and a suffix specifying whether the record represents an individual (_I) or an entity (_E). For example, HMT_I. Customer data have a record type of CUST_I for individual records and CUST_E for entity records.
   The higher the weighting number, the more the corresponding risk element contributes to the overall risk score. The weighting scores for each row must add up to 1.
   The overall risk score calculation for a record containing n elements is as follows:
   Risk Score = E1w1 + E2w2 + …+ Enwn/W1+W2+ W3…..+Wn (which has valid E risk element)
   E1, E2, E3, till En stand for scores for risk element. For example, country code, residency code, nationality code, and so.
   W1, W2, W3 till Wn stand for the element weightage from the above reference data. Where the risk element score for element x is represented by Ex and the weighting for element x is represented by wx.
   The total of all weightings must add up to 1, that is, (w1 + w2 + …+ wn = 1)

   Note:

   If there is no data for a risk element, it must not be included in the risk score calculation.
