Unpaid loss and LAE reserves represent management estimates of what the ultimate settlement and administration of claims will cost, generally utilizing actuarial expertise and projection techniques, at a given accounting date. The process of estimating loss reserves involves a high degree of judgment and is subject to a number of variables. These variables can be affected by both internal and external events, such as: changes in claims handling procedures, including automation; adverse changes in loss cost trends, including inflationary pressures, technology or other changes that may impact medical, auto and home repair costs (e.g., more costly technology in vehicles resulting in increased severity of claims); economic conditions, including general and wage inflation; legal trends, including adverse changes in the tort environment that have continued to persist for a number of years (e.g., increased and more aggressive attorney involvement in insurance claims, increased litigation, expanded theories of liability, higher jury awards, lawsuit abuse and third-party litigation finance, among others); and legislative changes, among others. The impact of many of these items on ultimate costs for loss reserves could be material and is difficult to estimate, particularly in light of ongoing disruptions to the supply chain and labor market. Loss reserve estimation difficulties also differ significantly by product line due to differences in claim complexity, the volume of claims, the potential severity of individual claims, the determination of occurrence date for a claim and lags in reporting of events to insurers, among other factors.
The increase in inflation in recent periods has increased our loss costs in our auto and property businesses. It is possible that, among other things, past or future steps taken by the federal government and the Federal Reserve to stimulate or support the U.S. economy, including actions taken in response to COVID-19, supply chain issues and labor shortages, could lead to higher and/or prolonged inflation, which could in turn lead to further increases in our loss costs. The impact of inflation on loss costs could be more pronounced for those lines of business that are considered "long tail," such as general liability, as they require a relatively long period of time to finalize and settle claims for a given accident year or require payouts over a long period of time. The estimation of loss reserves may also be more difficult during extreme events, such as a pandemic, or during volatile or uncertain economic conditions, due to unexpected changes in behavior of claimants and policyholders, including an increase in fraudulent reporting of exposures and/or losses, reduced maintenance of insured properties, increased frequency of small claims or delays in the reporting or adjudication of claims.
We refine our loss reserve estimates as part of a regular, ongoing process as historical loss experience develops, additional claims are reported and settled, and the legal, regulatory and economic environment evolves. Business judgment is applied throughout the process, including the application of various individual experiences and expertise to multiple sets of data and analyses. Different experts may apply different assumptions when faced with material uncertainty, based on their individual backgrounds, professional experiences and areas of focus. As a result, these experts may at times produce estimates materially different from each other. This risk may be exacerbated in the context of an extreme event or an acquisition. Experts providing input to the various estimates and underlying assumptions include actuaries, underwriters, claim personnel and lawyers, as well as other members of management. Therefore, management often considers varying individual viewpoints as part of its estimation of loss reserves.
Due to the inherent uncertainty underlying loss reserve estimates, the final resolution of the estimated liability for claims and claim adjustment expenses will likely be higher or lower than the related loss reserves at the reporting date. In addition, our estimate of claims and claim adjustment expenses may change. These additional liabilities or increases in estimates, could vary significantly from period to period and could materially and adversely affect our results of operations and/or our financial position.
