Every individual and his integrity, property and economic activity are constantly exposed to certain dangers from which they are insured, and it is not possible to prevent them in advance. The purpose of insurance is not to make money on insurance, but to protect against the consequences of future harmful events. Insurance is an economic activity which provides interested persons with economic protection from various risks that endanger their life, health or property, in the event of an accident that causes damage from which the interested persons are insured. The basic function of insurance is considered to be compensation for damages, while the basic participants in insurance are the insurer, the policyholder, the insured and the reinsurer. The subject of the insurance can be a material object, property, person or anything else that can be injured, damaged or destroyed. The insurance market is the overall relationship between providers and seekers of insurance products, and the Republic of Croatia, by joining the European Union, has become part of the largest insurance market in the world, the European insurance market. One of the largest insurance companies in Croatia are Croatia osiguranje, Allianz, Euroherc and Adriatic osiguranje.
