Reinsurance is typically defined as the process of buying insurance from other insurance companies, by any insurance company to mitigate or minimise the own risk. The process is generally used by insurance companies to share risk with others to limit their own loss in case if a risk is having a high probability of demanding compensation.
Facultative reinsurance as the name suggests offers protection against a risk or a block of risks to the primary insurer's book of business.
