Management, verbatim
Book value per share was up 4% in the quarter, driven by strong operating company results and solid investment returns.
Liam Caffrey, CEO
Gross premiums were down 5% in the quarter driven by rate softening in property lines, which offset solid growth in specialty lines. The Iran war losses to date have been manageable but uncertainty remains.
Ian Beaton, CEO of Ark
We delivered a strong second quarter and start to the year, generating a 4% return in the quarter and a 15% return on a trailing 12 months basis.
Rob Jakacki, CEO of Kudu
