23. Notion and purpose of reinsurance. Types of reinsurance contracts.

Reinsurance is a method used by an insurance company in order to reduce its liability for a policyholder. This method consists of transferring a part of the policyholder’s coverage to another insurance company.

The purpose of reinsurance is to share large risks with other companies. It also allows an underwriter to assume more liability.

Benefits of reinsurance are:

• Expansion of an insurance company capacity

• Stabilization of its underwriting results

• Financing of its expanding volume

• Securitization of catastrophic protection against shock losses

Reinsurance absorbs and distributes the effects of the insurance industry’s losses so that no single company is overburdened with the financial responsibility of offering coverage to its policyholders. Without reinsurance, the effects of unexpected catastrophes, unanticipated liabilities or a series of large losses could be too great for an insurer to absorb, forcing it into insolvency.

Reinsurance serves to limit liability on specific risks, to increase individual insurers’ capacity, to share liability when losses overwhelm the insurer’s resources, and to help insurers stabilize their business

Direct Insurer, who transfers a part of its obligations to a reinsurance company, is called a ceding company.

Functions of reinsurance

  • Risk transfer: the main use of any insurer that might practice reinsurance is to allow the company to assume greater individual risks than its size would otherwise allow, and to protect a company against losses. Reinsurance allows an insurance company to offer higher limits of protection to a policyholder than its own assets would allow.

  • Income smoothing: reinsurance can help to make an insurance company’s results more predictable by absorbing larger losses and reducing the amount of capital needed to provide coverage.

  • Surplus relief: an insurance company's writings are limited by its balance sheet. When that limit is reached, an insurer can stop writing new business, increase its capital or buy "surplus relief" reinsurance. The latter is usually done on a quota share basis and is an efficient way of not having to turn clients away or raise additional capital.

  • Arbitrage: an insurance company may be motivated by arbitrage in purchasing reinsurance coverage at a lower rate than what they charge the insured for the underlying risk.

  • Contract Types

  • Reinsurance contracts can be split between two basic types that can further be subdivided into three different subcategories. The first two basic types of reinsurance contract that exist are

  • the treaty (automatic risks) : under a treaty contract, a reinsurer agrees to cover all risks that the insured is writing during the specified period within the stated parameters set out in the treaty. The ceding company, in this case, provides the reinsurers with a list of risks ceded to the treaty- bordereau.

  • the facultative (individual risks): under a facultative contract, the reinsurance contract will cover risks on an individual basis.

The form the coverage takes can be split into either of

  • excess-of-loss,

  • proportional,

  • loss portfolio transfer.

An excess-of-loss approach covers losses arising above a specified loss threshold that the ceding insurer retains.

Under a proportional approach, the ceding insurer will simply share all losses, fees and premium on a pre-determined basis with the reinsurer.

A transfer of portfolio losses is an agreement under which the ceding company will transfer all reserves that it has accumulated for a block of policies to the reinsurer.

Types of reinsurance cover:

• Proportional- premiums and claims are divided between insurer and reinsurer at a defined ratio

- Surplus treaty- reinsurer agrees to accept some amount of insurance on each risk in excess of a specified net retention.

- Quota-share- a fixed proportion of every risk is reinsured.

• Non-proportional- premiums and claims are not fixed when the cover starts (based on losses rather than sums insured)

- Excess of loss- when a claim exceeds an agreed amount

- Stop loss- protects a cedent against an aggregate amount of claims over a period, in excess of a specified percentage of the earned premium income.
