The Company offers casualty and specialty reinsurance products to insurance and reinsurance companies and provides coverage for specific geographic regions or on a worldwide basis. Principally all of the business is reinsurance, although the Company also writes insurance business. As with the Company’s Property segment, its Casualty and Specialty segment reinsurance contracts can include coverage for relatively large limits or exposures. As a result, the Company’s casualty and specialty reinsurance business can be subject to significant claims volatility. In periods of low claims frequency or severity, the Company’s results will generally be favorably impacted while in periods of high claims frequency or severity the Company’s results will generally be negatively impacted. The Company’s processes and methodologies in respect of loss estimation for the coverages offered through its Casualty and Specialty segment differ from those used for its Property segment. For example, the Company’s casualty and specialty coverages are more likely to be impacted by factors such as long- term inflation and changes in the social and legal environment, which the Company believes gives rise to F-47
