On the reinsurance side, what type of premiums have you seen these companies move into or out of?  

If you're utilizing this model, it's better suited for long-tail scenarios, where payouts are not immediate but predictable. This is typical for sectors like life reinsurance. Markel, for instance, doesn't deal in life reinsurance at all, which is surprising given the significant amount they still have on their books from the acquisition of Max Re. Initially, Alterra, known as Max Re, engaged heavily in reinsurance deals for life insurance because it's very predictable. You generally know the annual mortality rates and the approximate payouts. Additionally, life reinsurance isn't significantly impacted by natural disasters like hurricanes or earthquakes, though there are some effects. The payouts are also deferred over a long period.
