A reinsurer is an entity that provides reinsurance coverage, assuming part or all of the risk liability held by a primary insurer. Essentially, a reinsurer enables insurance companies to mitigate risk exposure, maintain financial stability, and expand their underwritten policies by transferring parts of their potential losses to the reinsurer.
Types of Reinsurance
Proportional Reinsurance
In proportional reinsurance, also known as pro-rata reinsurance, the reinsurer and the insurer share the premiums and losses in a pre-agreed ratio. For instance, in a 50/50 treaty, both parties equally share the premiums and the claims.
Example:
If the primary insurer underwrites a policy with a premium of $1,000 and a claims expense of $600, a 50/50 reinsurance agreement would mean the reinsurer gets $500 in premiums and pays $300 in claims.
Non-Proportional Reinsurance
Non-proportional reinsurance, often referred to as excess of loss reinsurance, is where the reinsurer covers the losses exceeding a specified threshold. The reinsurer does not share the premiums but takes on any significant losses above the set point.
Example:
If a primary insurer has an excess of loss agreement with a threshold of $200,000 and a claim of $300,000 occurs, the reinsurer would cover $100,000 (i.e., the amount exceeding the threshold).
Historical Context
Reinsurance has been integral to the insurance industry since the 14th century with earliest records in Genoa, Italy. It evolved significantly through the centuries, driven by major risk events such as natural disasters and economic disasters which necessitated broader risk-sharing mechanisms.
Applicability
Risk Management
Reinsurers play a crucial role in risk management by helping primary insurers manage large exposures and stabilize their financial positions. By transferring risk, insurers can underwrite more policies than their capital would otherwise support.
Financial Solvency
Reinsurers aid in maintaining the solvency of primary insurers. They ensure that insurers have the financial backing to cover high magnitude claims, thereby protecting policyholders and maintaining market confidence.
Market Expansion
Reinsurers enable insurers to expand their market reach by accepting large numbers of policies without increased risk.
