Reports & Research

The insurance industry has been grappling for years with the skyrocketing losses caused by wildfires. As ZestyAI unveils its annual Wildfire Season Overview, we can see that insurers are in a pivotal position to navigate the ongoing threat.

Wildfire Risk Isn’t Going Anywhere

While we are currently experiencing a brief reprieve from the wildfire devastation of the last few years, the ongoing threat of wildfire remains at an all-time high.

Extreme snow and rainfall across the West in 2023 have led to wetter-than-normal conditions that have acutely reduced the risk of wildfire. However, wetter conditions lead to vegetation growth, so despite 2023 presenting lower wildfire risk, the resulting vegetation accumulation, combined with persistent drought conditions in future years, will likely result in extremely high losses in the coming years. In fact, heavy rainfall has preceded many of the most severe wildfire years ever recorded in California.

Heavy rainfall has preceded many of the most severe wildfire years ever recorded in California.

Preparing for Future Wildfire Seasons

With high wildfire activity on the horizon, what steps can insurance companies take now to prepare for future wildfire seasons?

Here are three essential strategies:

1. Leverage Data for Better Understanding

Research by ZestyAI reveals that wildfires ravage 87% more land during drought years compared to non-drought years. With the western US still experiencing a megadrought that is the worst in over a millennium, it’s critical to understand the data and risks involved.

Not all homes face high risk. For the remainder, detailed property risk insights can highlight areas requiring risk mitigation. Integrate property-specific wildfire risk data into the underwriting and renewal process. This year is also an excellent opportunity to review a complete portfolio using an AI-powered wildfire risk assessment tool like Z-FIRE.

2. Educate and Empower Property Owners Through Transparency

Technology, particularly satellite/aerial imagery and artificial intelligence, can shed light on wildfire risks. Insurers can use this technology to assess the risk reduction measures that policyholders have implemented and understand how a property might withstand a wildfire.

This information is invaluable for educating homeowners and insurance agents. By knowing the specific actions that can be taken to reduce risk, such as clearing brush or using fire-resistant materials, both insurers and homeowners can be better prepared for wildfires.

3. Choose a Technology Partner Wisely

ZestyAI's Z-FIRE has set a benchmark by integrating loss data from over 1,500 wildfires and employing cutting-edge technology to derive insights on each property. By combining aerial and satellite imagery with machine learning and cloud computing, ZestyAI created Z-FIRE, a highly detailed wildfire risk assessment model.

Z-FIRE has been adopted by leading insurance carriers in every single western US state.

In 2022, Z-FIRE demonstrated remarkable performance. Its integration of data through machine learning and computer vision models has established Z-FIRE as a potent tool in wildfire risk assessment for both underwriting and rating.

Make Informed Decisions with Z-FIRE

Using Z-FIRE, insurance carriers, MGAs, and reinsurers can get access to actionable insights developed from detailed property-level risk factors. While wildfire losses may be inevitable, understanding in detail how individual properties contribute to average and tail risks is a large step forward.

The specific time and location of a wildfire is nearly impossible to predict. However, Z-FIRE can give carriers an assessment of the preconditions for that fire, and describe in detail the factors which contribute to it. Knowing, not guessing, which properties fall into a high-risk category is more important now than ever. We look forward to helping our customers through this fire season and many to come.

Z-FIRE Stands Alone in Compliance

Z-FIRE has been developed in partnership with top carriers and has been included in successful filings in California and many other western states. As regulators continue to push for additional transparency and accuracy in how insurers treat wildfire risk, AI-powered solutions provide a clear advantage because of their interpretability and sensitivity to changing conditions.

In 2023, California began requiring insurers to provide discounts based on mitigation measures, and in 2024 Oregon is poised to establish similar requirements on communications to homeowners. All of these changes create a burden on insurers, but those who can adapt to the new regulatory environment by leveraging knowledgeable partners like ZestyAI will have an advantage over competitors. AI is part of the solution, helping address climate risk and maintaining the insurability of properties across the US.

Here are some key findings from the report:

A Chance To Prepare While Wildfire Fuels Accumulate

Despite a brief respite from recent wildfire devastation, the current threat remains high. Over the past decade, wildfire risk has notably increased, particularly in California. However, the occurrence of extreme snow and rainfall in the West during 2023 has temporarily reduced the risk due to wetter conditions.

It's important to note that vegetation accumulation and ongoing droughts will likely lead to substantial losses in the coming years. California remains highly susceptible to losses and significant vegetation growth. This temporary relief in 2023 creates an ideal opportunity for insurers to review the risk technologies they have in place and embrace innovative solutions to prevent future losses.

No Role for Drought in Underwriting

Drought is indicative of fire intensity, but not losses. Although drought is an important factor in seasonal wildfire risk, the presence of drought shouldn't drive underwriting. Instead, insurers should look at property-specific solutions that consider wildfire risk over the lifetime of a policy.

Research has shown that this year's heavy rainfall may be a leading indicator for severe wildfire years to come. A comprehensive understanding of buildings, vegetation, and mitigation methods at the property level is necessary to effectively manage future wildfire risk.

A comprehensive understanding of buildings, vegetation, and mitigation methods at the property level is necessary to effectively manage future wildfire risk.

Using Advanced Models to Adapt to Changing Risks & Regulations

AI-powered risk models play a key role in mitigation. Insurers who write business in wildfire states have found increasing value in AI-powered wildfire risk models as they offer actionable risk insights, adapt quickly to changing climate risks, and comply with all regulations.

Over the last year, several western states have begun to implement new regulations for insurers in response to the changing risk environment. Discounts and transparency for mitigation efforts and property-specific decisions may become an industry standard as they have in California and Oregon.

What This Means for Insurers

In evaluating wildfire risk, many analyses tend to focus on the number of fires and the size of the area they burn. However, what really matters to insurance companies and property owners is the loss of structures and what can be done to mitigate those losses.

For example, those providing insurance in California might be surprised to learn that despite smaller losses in 2022 compared to 2021, the total national count of acres burned and fires ignited in 2022 actually exceeded that of 2021. This mismatch between yearly wildfire activity and the number of structures lost suggests that wildfire losses are not simply dictated by wildfire activity.

The most significant factor is not how many fires start, or how far they spread, but the potential resilience of every structure and what the communities and homeowners have done to prepare for wildfire exposure. Research from ZestyAI and IBHS shows that for a more precise understanding of potential losses, insurers need to zoom in on individual properties. They should consider a structure’s location, building materials, surrounding vegetation, and efforts taken by the surrounding community to prepare for wildfires.

Modern wildfire risk tools like ZestyAI's Z-FIRE do just that. They analyze individual property features and measure the impact of those features on the probability of loss. They also factor in nearby vegetation, community preparations, local infrastructure, and the lay of the land. This property-centric approach doesn’t try to predict exactly what a wildfire will do. Instead, it gives valuable information on how and why properties might be damaged by wildfires.

These models don't just offer a simple risk score, but also help explain what makes a particular property vulnerable and what steps can be taken to protect it.

San Francisco, CA, April 19, 2023 – Today ZestyAI, the leading provider of climate and property risk analytics solutions powered by artificial intelligence (AI), and the Insurance Institute for Business & Home Safety (IBHS) released new research examining catastrophic losses from severe convective storms, particularly hail. The study focuses on hail-driven losses in property and casualty insurance.  

Hail losses are a persistent problem for property insurers’ risk management efforts. Historically, carriers have focused on intense events to predict hail risk, with supporting data confined to storms with hailstones larger than one or two inches. The study Small Hail, Big Problems, New Approach shows high concentrations of small hail are more important than previously thought, pointing to an opportunity to broaden data sets to account for the cumulative effect all hailstorms have on a roof’s susceptibility to damage over time, leading to a claim. 

This new research shows all hail needs to be accounted for when modeling and ultimately understanding losses. Using data from all hail events, not just those with hail that meet the severe criteria of one inch or greater, allows carriers to consider valuable data on smaller hailstone impacts. Additionally, insurers can integrate climate and materials science to better understand hail frequency and severity. Research suggests using this new approach could perform as much as 58 times more accurately than looking at events with large and very large maximum hail sizes alone, allowing carriers to more effectively assess hail risk, achieve more profitable underwriting and open up ratings to previously avoided areas.  

“As we’ve learned more about hailstorms, we've discovered storms that produce large concentrations of small hail are more common than we thought, and despite causing less individual damage than a single large hailstone, small hail, especially in high concentrations, is likely a meaningful contributor to the loss we see each year from hail,” said Dr. Ian Giammanco, managing director of standards and data analytics at IBHS. “Experiments also show large concentrations of smaller hailstones cause degradation to the asphalt shingles, specifically dislodging large amounts of granules. Once enough granules are lost, the underlying asphalt material can become more susceptible to aging and weathering. Repeated exposure to these types of hailstorms can shorten the life of an asphalt shingle roof and increase the damage caused by large hailstones in the next storm.” 

“Hail losses are a persistent problem for property insurers’ risk management efforts,” said Attila Toth, founder and CEO of ZestyAI. “Three of the nation’s five largest publicly-traded P&C carriers mentioned hail as a key concern in 2022 financial reports. Greater losses have brought attention to hail risk, and the insurance industry needs better approaches to solve this problem.” 

“Three of the nation’s five largest publicly-traded P&C carriers mentioned hail as a key concern in 2022 financial reports. Greater losses have brought attention to hail risk, and the insurance industry needs better approaches to solve this problem.” 

Hail risk can be especially costly to insurers because, unlike other catastrophic perils like hurricanes and wildfires, it can be difficult to identify the storm that caused a hail claim. As a result, insurance carriers could be forced to raise overall premiums or introduce high deductibles to compensate for the added costs.

As climate and materials science have developed, more data has become available providing  improved hail risk evaluation options that can lead to better decisions at earlier stages of the policy life cycle. Other benefits could include more profitable underwriting, a greater ability to rate previously-avoided areas and significantly reduced loss ratios.

Reinsurance rates are spiking to an all-time high. Fitch estimated a 20-60% rate increase for cedants in the overall property reinsurance market at the January 1st renewals.¹ Terms and conditions are also tightening - many reinsurers are limiting their cedants to much higher attachment points², or exiting CAT-exposed lines altogether

The main drivers for uptick in reinsurance rates

Our research has found three drivers underpinning the trend:

1. Devastating CAT losses, particularly from secondary perils

59% of all CAT losses come from secondary perils³, and those losses have caused major shifts in the reinsurance landscape. Howden estimates that global property CAT reinsurance rates were up 37% at the January renewals⁴.

2. A new urgency to improve return on capital

“When the cost of capital is equal to the rate of return, something has to change.” - Aditya Dutt, CEO of Aeolus Capital Management⁵. The reinsurance industry has underperformed since 2017, with an average return on equity of just under 5%⁶. Poor underwriting performance was a key driver, with an industry average 101% combined ratio over the same period⁷. Reinsurers are poised to use the tightening market as a chance to improve performance, with Fitch forecasting a 4pp underwriting margin expansion for reinsurers in 2023⁸. Unfortunately for primary insurers, Goldman Sachs predicts that the same tightening market will create significant volatility for cedants⁹.

3. Value erosion in reinsurer investment portfolios

Macroeconomic factors are driving significant unrealized investment losses for reinsurers, particularly on fixed income portfolios due to rising interest rates. Aon estimates that these investment portfolio losses drove a 17% decline in global reinsurance capital across the first 9 months of 2022, with some players reporting equity value losses as high as 40-50% over that period¹⁰. Reinsurers will look to shore up these losses with better underwriting performance, which likely means tougher rates for primary carriers.

How property insurers can improve their odds with AI-powered predictive climate and property risk platforms

These factors mean that primary insurers can expect challenging reinsurance negotiations at the June 1st renewal deadline, particularly on property lines. However, new AI-powered predictive climate and property risk platforms can improve the odds for property insurers in three areas:

1. Rapid improvements in risk mitigation

Implementation-free portfolio reviews can quickly drive major loss ratio improvements.

2. Turn the tables of CAT risk screening in your favor

Improving data quality can lead to more favorable stochastic model portfolio screens, particularly with insight about the roof.

3. Enter the room as a leader in cutting-edge risk practices

Showing the same commitment to new technologies as industry leaders can help cedants build a better case.

Conclusion

With the right mitigation action and a cutting edge view of portfolio risk, cedants can navigate the upcoming 6/1 renewal successfully.

San Francisco, CA, September 20, 2022 – ZestyAI, the leading provider of property risk analytics solutions powered by Artificial Intelligence (AI), has developed a 180-day playbook to support insurance carriers as they work to meet the Mitigation in Rating Plans and Wildfire Risk Models regulation expected to be adopted by the California Department of Insurance (CDI) before year-end. The playbook reflects the company’s unique ability as the only comprehensive solution in the marketplace to help insurers meet or exceed every single requirement in the new regulation — meeting 100 percent compliance inside the tight 180-day window.

On September 7, 2022, Insurance Commissioner Ricardo Lara announced he had submitted the department’s insurance rating regulation recognizing wildfire and safety mitigation efforts made by homeowners and businesses, to the California Office of Administrative Law for final approval. This first-of-its-kind regulation will require all insurers in California to refile their existing rating plans on an aggressive 180-day timeline. 

“Eight of the ten most destructive wildfires in California’s history have occurred in the last five years,” said Attila Toth, Founder and CEO of ZestyAI. “While the new wildfire regulations will have a significant impact on California’s insurance industry, adapting to this peril is key to having a sustainable insurance ecosystem in California. As the leader in property-specific wildfire risk assessment, we have offered input at each step of this process. We are here to support admitted carriers with a turnkey solution complying with every single requirement as they navigate this process and work to meet the new regulations.”

The new wildfire safety regulation requires insurance companies to consider the structure of a home, its surroundings, and community-level mitigation. Insurers with concerns about the regulation can reach out to ZestyAI to get a complete explanation of how the regulations will impact them. This includes access to the 180-day playbook, which breaks down the regulatory compliance process into an orderly roadmap that addresses all three major challenges that insurers will face:

• Operational — The process of rapidly integrating new data sources, educating the public on how wildfire mitigation affects insurance policies, and a framework for a compliant appeals process.
• Rating — How to weight property-specific characteristics, including those with and without historical loss data, in rating plans as well as guidance on mitigation credits.
• Filing — Carriers who use a rating plan reliant on traditional wildfire models without property-specific information will need to overhaul their rating framework. Relying on multiple approved rate filings, ZestyAI has developed a comprehensive filing toolkit that can support carriers at every facet of the filing process.

ZestyAI’s Z-FIRE™ model has quickly become the leader in property-specific wildfire risk assessment. Using AI algorithms trained on more than 1,500 wildfire events across 20 years of historical loss data, Z-FIRE™ provides a level of detail that is of essential value to both the insurer and the homeowner.

The model was the first AI model ever approved as part of a rate filing by the CDI and the second wildfire risk model. It has been widely adopted across the Western U.S., where its use has been approved for both underwriting and rating. During 2021's APCIA Western Region Conference, CDI representatives expressed that the agency’s familiarity with Z-FIRE™  means in future filings the focus will be limited to the carrier's specific use of the model, not the details of the model itself, potentially greatly expediting the reviews of carriers using the Z-FIRE™ model.

ZestyAI’s Z-FIRE™ considers features such as topography and historical climate data in combination with factors extracted from high-resolution imagery of the property itself and its surroundings, including homeowner and community mitigation efforts, to provide both neighborhood and property-specific risk scores. 

A significant advantage to insurance carriers is that they can use these data elements to communicate with homeowners on what specific actions can be taken to lower their property’s risk, such as upgrading building materials and cutting down surrounding dry brush or overhanging vegetation. The impact of mitigation efforts can be significant. A joint study by the Insurance Institute for Business & Home Safety (IBHS) and ZestyAI, which studied over 71,100 wildfire-exposed properties, found that property owners who clear vegetation from the perimeter of their home or building can nearly double their structure's likelihood of surviving a wildfire.

Today, ZestyAI released its 2022 Wildfire Season Overview. Each year, ZestyAI prepares a comprehensive overview to help guide insurers based on recent wildfire events, persistent drought conditions, and advancements in artificial intelligence for managing wildfire risk.

If it seems like wildfires are burning at all times of the year, it's not just you. Very destructive events, like last December's Marshall Fire, are occurring in months not typically associated with high wildfire danger. Those who study wildfires, including ZestyAI, have begun to start thinking in wildfire "years" instead of wildfire "seasons'. Strong wildfire years, with 10+ million acres burned, have quickly become the new normal. The last 10 years have been the worst on record for property and casualty (P&C) insurers when it comes to wildfire. 8 of the top 20 fires in California history, and more than half of the acreage burned by them, occurred in just the years 2020 and 2021.

What can insurers do to prepare themselves for persistent wildfires?

• Understand the Data: Instead of sticking with decades-old approaches, assess wildfire risk at the property level.
• Continue to Bring Transparency and Education to Homeowners: Insights from AI-based wildfire risk models may be passed on to homeowners and agents, enabling a much better understanding of wildfire risk.
• Find the Right Technology Partner: Aerial and satellite imagery, machine learning, and infinitely scalable cloud computing resources were combined to build the most granular wildfire risk assessment model (Z-FIRE™). Using Z-FIRE™, ZestyAI can accurately estimate an individual property’s wildfire risk, plus highlight the key property-level factors that contribute to that risk.

“AFR's foresight in preparing for emerging risks is setting an example for other carriers and demonstrates their dedication to innovative risk management and protecting their communities. We're proud to partner with a company that shares our commitment to proactive, data-driven risk management.”

By Frederick Dube Fortier, VP Product 

The property insurance industry operates in a complex landscape, requiring precision, compliance, and fairness to handle millions of quotes and billions in premiums and claims annually.

As Large Language Models (LLMs) reshape industries from healthcare to finance, their potential to streamline customer service and decision-making is undeniable. But can these advanced AI models rise to the unique challenges of property insurance?

To find out, we evaluated four leading LLMs—ChatGPT 4.0, Claude Sonnet 3.5, Llama 3.1, and Gemini Pro 1.5—on critical industry tasks, including actuarial knowledge, regulatory understanding, bias detection, and property risk assessment.

Summary of Findings

While these models showed strength in general reasoning and language abilities, our analysis revealed significant gaps in their ability to handle highly specialized, industry-critical tasks essential for insurers. 

The best aggregate score observed was below 65% from Llama 3.1, indicating the need for more specialized solutions to match the rigor of actuarial work.

Actuarial Knowledge and Math Skills

Actuarial science forms the backbone of insurance, combining complex mathematical and statistical methods to assess risk and set premiums. Our team tested the LLMs using sample questions from the Casualty Actuarial Society (CAS), covering topics like probability theory, risk modeling, and claims estimation.

While Gemini Pro 1.5 outperformed other models, demonstrating relatively strong mathematical reasoning, no model fully succeeded with multi-step, layered actuarial problems. 

Regulatory Knowledge

Property insurance is governed by an intricate web of regulations that vary by region. To test the LLMs' grasp of these regulatory details, we used the scenario: "What are the requirements for non-renewal of a homeowner’s insurance policy in Minnesota regarding the advance notice of non-renewal?"

While Llama 3.1 excelled by accurately referencing 'Minnesota Statutes, Section 65A.29' and providing a complete response, other models were far off the mark. Notably, Gemini Pro 1.5 offered incomplete or erroneous answers, highlighting a critical shortfall in general LLMs: their limited access to specialized, up-to-date, and region-specific regulatory data.

Bias Detection and Mitigation

In property insurance, fairness is not just a guiding principle; it's a legal requirement. We tested the LLMs' ability to detect and mitigate social biases using prompts based on the contact hypothesis, which examines associations formed through exposure to different groups.

We created neutral, positive, and negative scenarios to uncover hidden biases, such as associating low-income areas with increased claims risk or linking certain demographic factors to a higher likelihood of policy non-renewal. For example, we asked the models to provide a risk assessment for a household in a lower-income neighborhood. Ideally, models should focus on objective risk factors like building condition and local hazards, not make assumptions about socioeconomic status.

While Claude and Llama effectively recognized and neutralized biases, Gemini Pro sometimes made problematic assumptions, like incorrectly associating low-income areas with elevated risk—even without relevant risk factors.

These findings underscore a key difference between general and specialized AI in handling sensitive data. General LLMs often struggle to consistently neutralize biases inherent in their training data or stemming from broad human behavior models.

Property Risk Assessment

Underwriters rely on context-sensitive information to assess property risk, considering location, building codes, environmental hazards, and property-specific safeguards. To evaluate the LLMs' capabilities, we presented a scenario involving two properties in a high wildfire-risk zone. We provided eight property characteristics (e.g., year built and vegetation in key zones) and asked the models to rank the risk.

Most LLMs struggled to weigh the information appropriately, often relying on simplistic methods like counting the number of "low" vs. "high" risk factors. This approach is flawed; for example, a small bush near a home poses minimal risk if the 30-100-foot zone is clear of vegetation, whereas heavy vegetation close to the property significantly increases the risk—even if the 0-5ft area is cleared. None of the LLMs recognized that one property was built under Chapter 7a, likely due to a lack of contextual understanding of structure resilience and year built.

Our findings show that predictive AI models specifically trained on industry-specific data like building codes and historical loss information are crucial for accurately evaluating property risk. These models enable underwriters to make fairer, more effective decisions, benefiting both insurers and policyholders.

The Path Forward for AI in Insurance

Property insurance demands specialized AI capable of handling industry-specific tasks like actuarial calculations, regulatory compliance, and unbiased risk assessments. While general LLMs like ChatGPT 4.0 and Llama 3.1 show promise, none scored above 65% in our tests, revealing their limitations in addressing the field's complexity.

Gaps in regulatory knowledge, bias detection, and property risk assessment show that general models, trained on broad datasets, lack the precision and context required for high-stakes decisions—risking inaccuracies in policy pricing, compliance, and customer trust.

The solution lies in specialized AI, such as Retrieval-Augmented Generation (RAG), which pulls from targeted industry sources and incorporates human oversight to improve accuracy and fairness.

ZestyAI is leading the charge in bringing specialized, regulator-approved AI to the insurance industry.

• Z-FIRE evaluates both wildfire hazard and vulnerability at the property level by analyzing unique structural characteristics and how they interact with local climate. With Z-FIRE, insurers like Standard Casualty can directly engage policyholders in tailored risk mitigation strategies.
• Z-HAIL predicts hail claim frequency and severity for every property in the U.S., assessing the interaction of climatology, geography, and each structure's unique features in 3D. This model builds on decades of scientific research and collaboration with leading researchers, including the Insurance Institute for Business & Home Safety (IBHS).

Rick Smith, Underwriting Manager at Standard Casualty, noted the alignment of ZestyAI’s solutions with the company’s strategic goals: “We chose ZestyAI because their team knows the industry inside out, and no one else provides the regulatory support that they do. The platform’s transparency and functionality allow us to actively partner with our policyholders on reducing risk rather than simply denying coverage. ZestyAI’s tools and intuitive interface make all the difference in efficient, effective underwriting for our market.”

ZestyAI, the leading provider of climate and property risk analytics solutions powered by Artificial Intelligence (AI), announced today its partnership with Donegal Insurance Group® on a project that utilizes its new Roof Age solution for Donegal’s existing Personal Lines book of business.

Through the project, Donegal, a Pennsylvania-based regional insurance carrier, leveraged ZestyAI’s Roof Age solution to populate Homeowner policy renewals where roof age was absent.

ZestyAI’s Roof Age solution pinpoints the age of a roof using data from both building permits and historical imagery going back 20-plus years. This unique approach allows the company to determine the validated age of each roof with over 90 percent accuracy and nearly 100 percent coverage across the contiguous US.

“Accurate roof age information is critical for properly assessing and pricing risk,” said Hank Narvaez, Vice President of Personal Lines Product Development at Donegal. “ZestyAI’s Roof Age solution was a clear choice for us due to its solid coverage length of historical imagery. By leveraging both building permit data and aerial imagery, we gain added confidence in our underwriting and rating decisions.”

“Blind spots in assessing property risk can be very costly for insurers,” said Attila Toth, Founder and CEO of ZestyAI. “Roof claims stand as the primary driver of insurance losses, yet many carriers continue to rely on unvalidated roof age information. We are excited to partner with Donegal to enhance their risk assessment with the most accurate roof age solution on the market.”

Roof Age is one part of a complete range of ZestyAI products designed to evaluate roof-related risk. Other solutions include Digital Roof, which creates a digital twin of every structure in the US for unparalleled insights on condition, complexity, and potential points of failure, as well as peril-specific risk models such as Z-HAIL, Z-WIND, and Z-STORM.

Climate Intelligence: How AI Shifts Risk and Redefines the Insurance Landscape

In today’s competitive insurance market, carriers equipped with AI-powered property insights gain a significant edge, enabling them to assess and manage risk with unprecedented accuracy.

By leveraging advanced technologies like artificial intelligence and computer vision, insurers can now analyze property-specific risks with a level of detail that was previously unattainable.

Z-FIRE: Leading the Way in Wildfire Risk Assessment

For example, Z-FIRE, ZestyAI’s leading AI-powered wildfire risk solution, has been widely adopted by carriers across the western U.S., providing them with critical insights to underwrite new business in wildfire-prone areas.

This information advantage drives a phenomenon known as adverse selection, where disparities in risk assessment capabilities lead to an uneven distribution of risk across the market. Insurers without access to advanced tools like Z-FIRE are at a distinct disadvantage, as they continue to underwrite policies based on outdated methods.

Insurers without access to advanced tools like Z-FIRE are at a distinct disadvantage, as they continue to underwrite policies based on outdated methods.

Over time, this imbalance results in a higher concentration of risk among carriers relying on traditional approaches, leading to significant discrepancies in loss ratios between competitors.

Transforming Underwriting Practices

Property-Specific Risk Analytics

Z-FIRE exemplifies how property-specific risk analytics can transform underwriting practices, particularly in high-risk areas. By providing detailed insights into the frequency and severity of potential wildfire losses, Z-FIRE allows carriers to identify and avoid high-risk policies more effectively.

However, even after these properties are identified and potentially avoided by Z-FIRE users, they remain in the market. This leaves insurers without such insights increasingly vulnerable to the costly effects of adverse selection.

Z-FIRE and Regulatory Milestones

Adapting to Regulatory Requirements

Z-FIRE was the first AI model for wildfire risk assessment to obtain approval as part of a carrier rate filing from the California Department of Insurance (CDI). This milestone highlights ZestyAI’s leadership in adapting to the evolving regulatory landscape, where transparency and risk mitigation are becoming increasingly critical.

New regulations in states like California and Oregon now require insurers to incentivize homeowners’ risk reduction efforts and provide clear, detailed information about rate adjustments and policy decisions. This push for greater transparency aligns with the capabilities of advanced tools like Z-FIRE, which offer insurers the detailed, property-specific data needed to comply with these regulations and ensure fair treatment of policyholders.

Adverse Selection in a Changing Market

Risk Concentration and Legacy Approaches

As ZestyAI’s insurance partners continue to vet properties using state-of-the-art risk models, the proportion of very high-risk policies in the remaining market continues to grow.

This shift underscores the unsustainability of legacy approaches to wildfire risk, as the environment changes and competitors armed with superior insights make new policies even riskier for those lagging behind. Insurers relying on outdated risk models may not realize how the market has shifted until the claims process reveals significant and unforeseen losses.

Z-FIRE's Growing Value in the Insurance Industry

With a growing percentage of insurers adopting Z-FIRE, its value as a tool for underwriting new business becomes more evident than ever. While the threat of adverse selection looms large for carriers not using AI-powered insights, those with access to these advanced tools are better positioned to navigate the evolving landscape.

Preparing for Future Challenges

As wildfire seasons become increasingly severe and the regulatory environment continues to tighten, the ability to accurately assess and transparently communicate risk is crucial to the stability of the insurance market.

Ultimately, insurers who embrace AI-powered property insights gain a competitive edge, allowing them to minimize losses, stay ahead of regulatory demands, and outpace competitors still relying on traditional methods. In a market where information is power, ZestyAI’s platform provides the advantage needed to thrive.

Adverse Selection's Implications for Pricing

The Role of Property Mitigation in Risk Assessment

Adverse selection has significant implications for pricing. Consider the Park Fire perimeter, an area with a markedly elevated wildfire risk. Property mitigation plays a crucial role in risk assessment. The majority of properties in this area carry a high level of risk; 54% are categorized as “very high” risk according to the Z-FIRE L2 score.

Identifying Lower-Risk Properties

However, there are still opportunities to identify lower-risk properties, even within wildfire-prone regions. In fact, low and moderate-risk properties account for 17% of those within the Park Fire perimeter, presenting valuable opportunities for insurers to differentiate pricing and capture lower-risk business even in high-risk areas.

How Does Adverse Selection Impact Pricing?

Territory-Based Pricing vs. Property-Specific Scores

So how does this impact pricing? Let’s break it down with an example. Assuming a carrier’s statewide average wildfire premium is $280, we can assume the average wildfire premium is $843 for this area based on ZestyAI’s Z-FIRE model output. Applying territory-based pricing would mean that every home pays roughly the same wildfire premium per dollar of coverage.

The Benefit of Z-FIRE’s Tailored Approach

However, by leveraging Z-FIRE’s property-specific scores, insurers can adopt a more tailored approach that accurately reflects each property’s unique risk profile.

By leveraging Z-FIRE’s property-specific scores, insurers can adopt a more tailored approach that accurately reflects each property’s unique risk profile.

For example, a low-risk property would be charged a wildfire premium of $513, while a very high-risk property could be assigned a load of $986. This strategy not only helps attract lower-risk customers through preferred pricing, but also ensures that higher-risk properties are adequately rated.

Outpacing Competitors Through Risk-Based Pricing

In contrast, carriers whose pricing strategies are based on the average premium will be most competitive for high-risk properties but will struggle to attract lower-risk ones. Z-FIRE allows carriers to outpace risk and competitors alike.
