Everest Group provides property and casualty insurance and reinsurance, including catastrophe reinsurance that helps other insurance companies manage their exposure to large-scale losses from hurricanes, earthquakes and other major disaster events. As a reinsurer, Everest essentially provides insurance to other insurance companies, taking on a portion of the risk that primary insurers would otherwise have to bear entirely themselves, letting those primary insurers write more policies than their own capital would otherwise support. Its catastrophe reinsurance business can produce volatile results in any given year, since a single major hurricane or earthquake season can generate substantial claims, though pricing for this coverage typically reflects that inherent volatility over time. Everest Group's profitability depends on collecting sufficient premiums to cover eventual claims and expenses across market cycles, a relationship tracked through the combined ratio, while also investing its premium float to generate additional investment income.
