DOXA | The Rise of Algorithmic Underwriting: Revolutionizing Insurance

The insurance industry is undergoing a significant transformation with the increased adoption of algorithmic underwriting. This evolution brings enhanced decision-making, improved risk assessments, and optimized operations for insurers, ultimately elevating the customer experience.

The Evolution of Algorithmic Underwriting

Algorithms have long been integral to the underwriting process, primarily for rating purposes. For instance, in auto insurance, algorithms calculate rates based on factors like vehicle make, model, driver age, location, and driving history. These mathematical formulas have been essential tools for setting rates, but their use has been limited in other areas of underwriting.

Historically, the insurance industry relied heavily on complex rules engines for risk acceptance, tiering, and report ordering. This dependence arose due to concerns about overlapping rate-making factors and the lack of robust data and analytical capabilities in other underwriting stages.

However, advancements in data access and analytics are prompting a shift. Insurers are now leveraging algorithms, either independently or in conjunction with traditional rules engines, to enhance decision-making throughout the underwriting process.

How Algorithmic Underwriting Works

Algorithmic underwriting employs analytical models to automate decision-making or provide insights that assist underwriters. For more homogeneous risks, it can fully or partially automate the underwriting process.

Key decisions driven by algorithmic underwriting include:

Determining if a submission aligns with the carrier’s risk appetite
Identifying key risk characteristics, such as the correct SIC/NAIC code
Prioritizing accounts based on desirability and winnability
Making risk determinations on portions or the entirety of risk

This approach enables faster risk acceptance or rejection, reduces underwriting workloads, and offers customers personalized risk assessments, real-time risk management, and a seamless experience.

Five Advantages of Algorithmic Underwriting

Algorithmic underwriting offers significant benefits across five key areas:

Process Efficiency: Automating the underwriting process reduces processing times by up to 50%, streamlines operations, increases testing speed, and simplifies maintaining complex decision-making systems. Automated processes can handle up to 25% more applications, enabling insurers to increase premiums without additional operating costs.
Accuracy: Analyzing extensive data sets improves the accuracy of risk assessments by identifying patterns and correlations that might be missed by human underwriters. This augmentation of underwriter insight reduces errors and fraud, potentially decreasing fraud losses by up to 30% for some insurers.
Pricing: Enhancing risk assessments leads to more accurate pricing decisions. Algorithmic underwriting tailors premiums to individual risk profiles, enhancing customer satisfaction and competitiveness. It also supports dynamic pricing, adjusting premiums in real-time based on changing risk factors, potentially improving underwriting profitability by up to 20%.
Proactive Risk Management: Algorithms help insurers proactively identify emerging risks and adjust underwriting and risk management strategies, mitigating potential losses, reducing loss ratios, and improving overall portfolio performance.
Customer Experience: Instant or near-instant decisions on coverage eligibility, pricing, and personalized offers enhance customer experience. Predictive and prescriptive analytics enable real-time, contextualized offers, making insurance more accessible and relevant to individual needs and extending coverage to previously marginalized segments.

Building an Algorithmic Underwriting Platform at Scale

Creating an algorithmic underwriting platform requires a multi-layered approach that considers future scalability. Essential features include machine learning models, real-time risk assessment, and dynamic pricing models.

A robust algorithmic underwriting platform encompasses:

Machine Learning Models: Deep learning algorithms, natural language processing, and explainable AI.
Real-time Assessment: Dynamic adjustment of risk profiles and granular risk assessment.
Dynamic Pricing Models: Adjust premiums based on real-time data and individual risk profiles.

Challenges to Consider

When optimizing data and building an algorithmic underwriting platform, insurers must address several challenges:

Data Quality and Availability: Data may be fragmented, incomplete, or outdated.
Model Interoperability: Complex machine learning algorithms may lack transparency and interoperability, making outcomes difficult to explain.
Compliance: As regulation of algorithmic models and AI increases, insurers must stay ahead of the guidance and adjust models as needed.
Fairness and Bias: Without proactive measures, algorithmic underwriting risks perpetuating unfair practices and historic biases.
Data Privacy and Security: Collecting, processing, and storing large volumes of personal and sensitive data necessitates robust security measures to maintain compliance and customer trust.

Success Stories in Algorithmic Underwriting

The insurance industry offers several examples of successful algorithmic underwriting implementations. Ki Insurance uses AI and algorithms for instant commercial insurance quotes and automated policy issuance. Hiscox partnered with Google Cloud to develop an AI model that automates underwriting for specific products. On the life insurance side, Ethos employs machine learning to assess risk and simplify insurance applications.

Conclusion

While algorithmic underwriting is not new, its integration with advanced data sources, improved data quality, and better analytics tools revolutionizes the insurance landscape. These enhancements extend underwriters’ capabilities beyond traditional models and rules.

However, insurers must remain vigilant about potential biases and transparency issues in algorithmic models. Addressing ethics, compliance, data privacy, consumer protection, and fair lending laws from the outset is crucial.

As technology evolves and data analytics capabilities expand, algorithmic underwriting will continue to revolutionize the insurance industry. It will drive innovation, empower insurers to make informed, data-driven decisions, and ultimately enhance the customer experience.
