An example from commercial auto
Commercial auto is a line of business where risk scores can be especially valuable for insurers. Underwriting profit in commercial auto had been trending down for several years. In a study my company conducted as depicted below, AI modeling indicates commercial auto loss experience at the industry level were functions of (mostly) many geo-temporal macroeconomic and firmographic variables. Additional models looked at commercial auto litigation verdict amounts and large individual losses. Then models were trained to forecast injuries, accidents, fatalities, violations and more, per power unit. Ultimately, modeling accidents, injuries, and fatalities at the business level in a forward-looking way resulted in the most valuable predictive model(s) for underwriters: [caption id="attachment_231727" align="aligncenter" width="470"] (Source: Best's Market Segment Report; March 28, 2019)[/caption] A recent retrospective study looked at our proprietary risk models as of March 31, 2022, for all U.S. businesses that had a Department of Transportation number. We then recorded how many accidents, injuries and fatalities occurred for these businesses in future months (April – October), and then aggregated occurrences per power unit (shown in vertical axes in figures below) by risk score (shown in horizontal axes in figures below): The results showed a convincing (and expected) relationship between risk score and future accidents, injuries and fatalities per power unit. Businesses with higher scores experienced more of these events, on average, and businesses with lower scores experienced fewer of these events, on average. The study shows clearly that insurers with access to AI modeling would have been able to make decisions about current and potential insureds that would have resulted in better loss experiences in the year ahead. Within the commercial auto example, customers who were writing these policies have been avoiding the riskiest insureds or those with the highest scores. They have been able to prioritize the best risks (businesses with the lowest scores). And they have been able to charge more (less) premium for insureds with higher (lower) scores. For carriers, AI-powered risk modeling can enable better risk decisions, streamlined risk decision-making, and optimized underwriting–with faster quote-to-market. If thinking about implementing AI modeling to better inform underwriting, here are five key advantages to consider:
1. Increased underwriting productivity and speed to quote
Prioritizing and reviewing submissions is often very manual and cumbersome. Instead, underwriters can rapidly narrow risks within their appetite and deep dive on selected risks. A systematic approach reduces the administrative burden on underwriters and reduces the time to quote. Crum & Forster Insurance cut its surplus and specialty (S&S) lines operations submission processing time by half, enabling it to redeploy 40% of its contractors to higher-value roles and 20% of operations employees to revenue-generating roles.
2. Reduce underwriting operating costs
Automating the operational steps required for clearance and underwriting file preparation can significantly lower operational costs (FTE or BPO). For example, Columbia Insurance shaved off 20 minutes on average per submission, or a total of more than 2,500 hours per year in reviewing submissions.
3. Calibrate risk selection
As mentioned above, a single number measure of risk scoring, on a scale of zero to 100, can be used to evaluate the relative risk of insuring that business.
4. Pricing adequacy
By monitoring loss performance risk scores, customers can identify segments of their book of business where they have an opportunity to adjust pricing to better reach their target loss ratio
5. See growth of premiums

For example, Columbia Insurance Group reduced straight-through-processing on SMB policies by 28% within three months. John Stammen is CEO of Convr, revolutionizing the commercial underwriting process with cutting-edge AI and decision science. As a company leader, Stemmen brings strong critical thinking, vision and strategic planning, along with consistent value creation that creates repetitive customer success.
