The National Association of Insurance Commissioners has issued a new in-depth report on the 2021 market share data for insurers within the Property & Casualty marketplace. A total of 33 lines of business have been analyzed both at the national and state level. In response to the publication of this data, Agency Checklists is providing a distillation of the report over the coming weeks featuring the top insurers in various marketplaces in both Massachusetts as well as the rest of the New England states.
The NAIC states that the in-depth report may have a variety of useful purposes for individuals and entities by giving them an “understanding of the overall size of the market”. In addition, the NAIC notes that it may help:
Assess an insurer’s competitive position
Create benchmarks to compare companies
Identify the top writers
Analyze the overall size of the market
Identify premium volume trends
Evaluate market penetration potential
Evaluate post-merger market implications
