Appendix A: Data Validation

As well as unit record validation, overall reasonability checks will be carried out on each insurer’s data.

With each half-yearly data submission

Various comparisons between the current reporting period and the previous period will be carried out in order to monitor data reasonability and consistency. These may include:

• Change in the aggregate Gross Earned Premium, split by two digit ANZSIC code or single character occupation code;
• Changes in the total numbers of policies and claims;
• Counts of claims by various measures; causes of loss, severity or litigation status; and
• Changes in the average and total claims paid.

As well, various reasonability checks will be carried out within each period submission, including;

• Overuse of the various ‘Other’ categories and codes; and
• Comparison of the various premium fields against each other.

Other reasonability checks may be carried out on an ad hoc basis.
