Ongoing aim in producing this data is to provide market participants with an indication of the ongoing reinsurance capacity available in each market. Hence, we try to exclude intragroup reinsurance, as far as possible. Companies that have not been able to exclude intragroup reinsurance are highlighted in the footnotes.
