Better data quality equals more accurate view of insurance risk, pricing

IAG's New Zealand business can now geocode 90% of customer addresses

One way insurers assess risk is by knowing the exact location of an insured business or household using longitude and latitude geocode data rather than relying on a postcode. Using geographical information systems (GIS), insurers can pinpoint properties to their exact location and overlay them with risk ratings. This more accurately assesses the risk to a single property so premiums can be priced more equitably.

When Carl Rajendram joined IAG as National Manager for Commercial Pricing and Analytics, the first thing he noticed was a need for better data quality.

"There were a lot of fields captured in the core system that had not been validated, and we needed a solution to improve the data," he said.

The company wanted to ensure its customer address records achieved a better match rate with its geocoding tool. Already using SAS for data exploration and reporting, IAG turned to SAS for a risk-profiling solution.

"We are a team of five people who could have built something to achieve the result, but it would have taken three to four months," Rajendram says. "The 'off-the-shelf' SAS Data Quality Desktop solution returned the results we were looking for within one month."

The speed of execution was good. Within a week and a half, we were seeing a return on our investment.

'Quick win' justifies business case

Rajendram said SAS New Zealand was keen to support a quick win for IAG to produce a broader business case for the solution.

"We used the SAS Data Quality solution to validate our address data for accurate geospatial information to better manage the organisation's risk exposure," he says. "SAS spent a couple of days showing us how the solution could be used to standardise the addresses, and we were impressed with how quick and easy it was."

"As an extreme example, when it comes to pricing a premium, you can't compare Canterbury with Christchurch," Rajendram explains. "Previously, we were using codes from the Territorial Local Authority database, but these cover a wide area. SAS enabled us to go down to x and y coordinates, which has made a huge difference in our ability to price and understand our risk profiles."

Geocoding allows IAG to identify risk factors such as whether a property is on a slope or near the coast, and then make appropriate pricing and underwriting decisions.

Gain confidence to data quality

Rajendram says the tool provided clarity on data issues and improved confidence in the data itself.

"Before, only about 70 percent of addresses were of a standard that allowed geocoding," he says. "After we implemented SAS, the number exceeded 85 percent. Within a month of installing SAS, we achieved what we were after. And with a match rate of nearly 90 percent, we can now present this number to reinsurers with greater accuracy and confidence.

"The speed of execution was good. Within a week and a half, we were seeing a return on our investment," he says.

IAG now uses the solution for other projects. "We have initiated a data quality program for our commercial business division, which will form the start of a data governance project," Rajendram says. "We use it to profile some of the data and provide a feedback loop to stakeholders such as the distribution team, business owners and operational staff. This type of visibility wasn't available previously."
