Solvency II

Solvency II is a set of regulations that insurance companies in Europe have to follow. It is meant to help make sure that insurance companies have enough money to pay out the claims that they make to their customers. The rules require insurance companies to make sure they are saving up enough money to pay out any claims they might have to. They also have to report on their financial health to the regulators to make sure they are staying on top of their money situation.
