Underlying retention represents the net amount of risk or liability that an insurance company retains after transferring a portion of it to a reinsurer. This practice is instrumental in risk management for insurance companies, enabling them to mitigate potential large losses while still maintaining some level of exposure to the insured risk.
Mechanism of Underlying Retention
Definition and Core Concept
In simple terms, underlying retention is the portion of the risk that remains on the insurer’s balance sheet after reinsurance. Reinsurance is the practice where an insurance company transfers part of its risk portfolio to other insurance carriers, known as reinsurers. Despite transferring a portion of the liability, the original insurer retains a part of the risk, referred to as underlying retention.
Mathematically, if \( T \) represents the total insured amount and \( R \) is the amount reinsured, the underlying retention \( U \) is given by:
Types of Underlying Retention
- Fixed Amount Retention: A predetermined fixed amount of risk retained by the insurer.
- Proportional Retention: A percentage of each insurance policy’s risk that the insurer retains.
Factors Influencing Retained Amount
Several factors influence the decision on how much risk to retain, such as:
- Financial Strength of the Insurer: Stronger financials allow higher retention.
- Reinsurance Costs: Higher costs may lead to retaining more risk.
- Risk Appetite: A company’s willingness to accept risk impacts retention levels.
- Regulatory Framework: Legal requirements can dictate minimum retention levels.
Historical Context of Underlying Retention
The concept of reinsurance dates back several centuries, with historical records suggesting that early forms of risk-sharing and reinsurance were practiced as far back as the 14th century in Europe. The formalization of reinsurance contracts allowed insurers to better manage and distribute risks, leading to more stable and resilient insurance markets.
