Claims data

What Is Claims Data?

Claims data refers to the comprehensive collection of information related to requests made by policyholders to an insurer for compensation under an insurance policy. This data encompasses everything from the initial report of a loss to the final settlement or denial of the claim. Within the broader field of Insurance and Risk Management, claims data is a critical asset, providing insights into the frequency, severity, and nature of insured events. Insurers collect and analyze this data to understand past liabilities, project future obligations, and inform various operational and strategic decisions.

History and Origin

The systematic collection of claims data evolved alongside the formalization of the insurance industry itself. Early forms of insurance, such as marine insurance in the 17th century, relied on basic records of losses. As insurance expanded to cover more diverse risks, the need for more granular and accurate data became evident. The advent of statistical methods and later, computing, revolutionized how insurers processed and analyzed claims. Major catastrophic events, for example, have historically highlighted the importance of robust claims data for assessing financial impact and improving future preparedness. Superstorm Sandy in 2012, for instance, incurred an estimated $30 billion in insured losses, emphasizing the critical role of detailed claims data in understanding the financial consequences of large-scale disasters for the industry⁵.

Key Takeaways

• Claims data includes details on reported losses, investigations, and payouts.
• It is essential for insurers to assess risk, price premiums, and manage reserves.
• The analysis of claims data helps identify trends, detect fraud, and improve customer service.
• Regulatory standards, such as IFRS 17, mandate specific disclosures and calculations based on comprehensive claims data.
• Technological advancements continue to enhance the collection and analysis of claims data.

Formula and Calculation

While claims data itself is a dataset, it forms the basis for numerous actuarial calculations. One fundamental calculation that heavily relies on claims data is the loss ratio, which measures the proportion of premiums paid out in claims.

The formula for the loss ratio is:

Where:

• Total Incurred Claims represents the sum of paid claims and the change in reserves for unpaid claims over a period.
• Earned Premiums are the portion of the premium that applies to the expired part of the policy period.

This ratio provides a crucial indicator of an insurer's underwriting profitability.

Interpreting Claims Data

Interpreting claims data involves examining various metrics and trends to gain actionable insights. Analysts look at metrics such as claim frequency (how often claims occur), claim severity (the average cost per claim), and claims duration (how long it takes to settle a claim). For instance, a rising claim frequency for a specific type of coverage might indicate an emerging risk, while an increase in claim severity could point to inflationary pressures on repair costs or medical expenses. The insights derived from claims data inform underwriting guidelines, helping insurers refine their risk selection processes. It also guides the development of new insurance products and the adjustment of existing ones to reflect current market conditions and risk landscapes.

Hypothetical Example

Consider "SafeDrive Auto Insurance," a fictional company that wants to analyze its claims data for small fender-bender accidents in a specific geographic area.

1. Data Collection: SafeDrive collects all reported claims for fender-benders over the past year. This includes the date of the accident, the estimated damage cost, the actual payout, and details about the vehicles and drivers involved.
2. Analysis: They observe 1,500 such claims, with an average payout of $2,500. A closer look at the claims data reveals that accidents reported on rainy days have, on average, 15% higher damage costs. Furthermore, claims involving drivers under 25 tend to have a 10% longer settlement period.
3. Actionable Insight: Based on this, SafeDrive might consider adjusting premium rates for drivers in areas with high rainfall or for younger drivers, or they might implement targeted risk management campaigns for these groups. They might also streamline their claims processing for specific claim types to improve efficiency.

Practical Applications

Claims data is fundamental across numerous facets of the financial services industry:

• Product Development and Pricing: Insurers use claims data to accurately price new policies and adjust existing ones, ensuring that premiums reflect the underlying risk. This involves detailed statistical analysis and often sophisticated actuarial science to forecast future losses.
• Risk Assessment and Management: Companies utilize historical claims data to identify emerging risks, assess their potential impact, and develop strategies for mitigation. This is crucial for disciplines such as catastrophe modeling, where claims from events like hurricanes or earthquakes are analyzed to predict future scenarios. As noted by Swiss Re, access to detailed claims statistics is indispensable for model building, especially as climate change effects become more apparent⁴.
• Fraud Detection and Prevention: Patterns in claims data can highlight suspicious activities. Insurers employ advanced fraud detection analytics to flag potentially fraudulent claims, thereby protecting their financial integrity. Regulatory bodies, such as the City of London Police's Insurance Fraud Enforcement Department (IFED), actively use claims intelligence to combat insurance fraud through enforcement actions³.
• Reinsurance and Capital Management: Reinsurers rely heavily on claims data from primary insurers to assess the risks they assume. For primary insurers, robust claims data helps optimize their reinsurance arrangements and manage capital effectively to maintain solvency.
• Regulatory Reporting and Financial Statements: Regulatory bodies require detailed reporting based on claims data to ensure the financial stability and transparency of insurance companies. For example, International Financial Reporting Standard 17 (IFRS 17) significantly alters how insurers recognize and measure insurance contracts, requiring granular claims data for new calculations and disclosures².

Limitations and Criticisms

Despite its immense value, claims data has limitations. One significant challenge is its backward-looking nature; it reflects past events and may not always accurately predict future trends, especially in rapidly changing environments like those influenced by climate change or emerging technologies. There can also be issues with the completeness or accuracy of claims data, particularly if claims reporting systems are inconsistent or prone to human error.

Furthermore, relying solely on claims data can sometimes lead to an incomplete picture. For instance, while claims data can show the insured economic loss from an event, it may not capture the total economic disruption or social impact that was uninsured or underinsured. Regulators also face challenges in ensuring that claims data reported by insurers provides a true reflection of the industry's health, with some noting that "closed" claims statistics might include denied claims, potentially skewing perceived efficiency¹. Over-reliance on historical patterns without considering future probabilities or external factors can lead to mispricing of risk or inadequate reserving.

Claims Data vs. Policy Data

While both are crucial for insurance operations, claims data and policy data serve distinct purposes. Claims data focuses on the losses incurred and the payouts made under existing policies. It details the event of a claim, its investigation, and its financial resolution. Key elements of claims data include the date of loss, type of loss, amount claimed, amount paid, and status of the claim.

In contrast, policy data pertains to the characteristics of the insurance contracts themselves. This includes information about the policyholder, coverage limits, deductibles, premiums, effective dates, and insured assets or liabilities. Policy data is generated before a loss occurs and is used for initial underwriting, pricing, and administrative purposes.

The confusion between the two often arises because they are inextricably linked. Policy data defines the terms under which claims data is generated. Insurers analyze claims data in relation to policy data to understand profitability per policy type, demographic, or geographic area, informing better regulatory compliance and strategic decisions.
