Quota Share Treaty
A quota share treaty is a proportional reinsurance contract that allows an insurance company to transfer a fixed percentage of each risk it underwrites to one or more reinsurers, establishing a proportional sharing of premiums, losses, and expenses.
What is a Quota Share Treaty?
A quota share treaty is a type of reinsurance contract that allows an insurance company (the cedent) to transfer a fixed percentage of each risk it underwrites to one or more reinsurers. This arrangement establishes a proportional sharing of premiums, losses, and expenses between the cedent and the reinsurer(s) based on the agreed-upon quota share percentage.
The primary purpose of a quota share treaty is to manage the cedent’s overall risk exposure and enhance its underwriting capacity. By ceding a portion of its business, the insurer can write larger policies or a greater volume of business than its own capital would typically allow, thereby diversifying its risk and stabilizing its financial results.
This type of treaty is characterized by its automatic nature, where all risks falling within the scope of the treaty are automatically shared. The reinsurer assumes a proportional part of the cedent’s liability, receiving a corresponding portion of the premium. This creates a direct and continuous relationship for all covered business.
A quota share treaty is a proportional reinsurance agreement where the ceding insurer transfers a fixed percentage of its risks, premiums, and losses to a reinsurer.
Key Takeaways
- A quota share treaty is a proportional reinsurance contract involving the automatic sharing of risks, premiums, and losses.
- It allows the ceding insurer to increase its underwriting capacity and manage exposure by transferring a fixed percentage of each policy.
- The reinsurer receives a proportional share of premiums and pays a proportional share of claims and expenses, creating a direct relationship for all covered business.
- This treaty type helps stabilize financial results and diversify risk for the primary insurer.
Understanding Quota Share Treaty
In a quota share treaty, the reinsurer acts as a partner, sharing in every policy written by the cedent within the treaty’s parameters. For example, if a cedent has a 50% quota share treaty with a reinsurer, for every policy written, the cedent retains 50% of the risk and transfers the other 50% to the reinsurer. This means the cedent also transfers 50% of the premium earned on that policy and is responsible for 50% of any claims paid.
The fixed percentage applies to all risks covered by the treaty, irrespective of their size or nature, as long as they fall within the predefined classes of business and geographical areas specified in the contract. This automatic sharing simplifies administration compared to facultative reinsurance, where each risk must be offered individually. The primary insurer benefits from immediate capacity enhancement and risk diversification without the need for individual risk assessment by the reinsurer.
The reinsurer’s compensation typically includes a share of the written premium, often adjusted by a commission or allowance to cover the cedent’s acquisition costs and administrative expenses. This commission is usually a percentage of the ceded premium, intended to offset the cedent’s underwriting expenses and provide the reinsurer with a net profit margin.
Formula
While specific calculations can vary, the fundamental principle of a quota share treaty involves direct proportional sharing. The basic calculations for ceded premium and ceded losses are:
Ceded Premium = Total Premium x Quota Share Percentage
Ceded Loss = Total Loss x Quota Share Percentage
Ceded Expenses = Total Expenses x Quota Share Percentage
The reinsurer also typically receives a ceding commission, which is a percentage of the ceded premium, to help cover the cedent’s expenses.
Real-World Example
Imagine an insurance company, “SecureHome Insurance,” specializing in homeowner’s policies. SecureHome enters into a 30% quota share treaty with “Global Reinsurance Company.” If SecureHome underwrites a new homeowner’s policy with a premium of $1,000 and a potential maximum loss of $100,000:
Under the 30% quota share treaty, SecureHome will retain 70% of the risk and premium, while ceding 30% to Global Reinsurance. This means SecureHome keeps $700 of the premium and transfers $300 to Global Reinsurance. If a claim occurs and the payout is $10,000, SecureHome will pay $7,000, and Global Reinsurance will pay $3,000.
This arrangement allows SecureHome to write more policies, knowing that a significant portion of the risk is automatically transferred. Global Reinsurance gains a diversified portfolio of business without having to select individual risks.
Importance in Business or Economics
Quota share treaties are vital for the stability and growth of the insurance industry. For primary insurers, they provide essential capital relief, enabling them to underwrite larger risks and expand their market reach without overextending their financial resources. This capacity enhancement is crucial for economic development, as it supports businesses and individuals by providing insurance coverage for a wider array of assets and liabilities.
From a macroeconomic perspective, widespread use of reinsurance, including quota share treaties, helps to smooth out the financial impact of catastrophic events. By spreading risks globally, the insurance industry is better equipped to absorb large losses, preventing insolvencies and maintaining confidence in the financial system. This contributes to overall economic resilience by ensuring that businesses and individuals can recover more quickly after major disasters.
Reinsurers, in turn, benefit from diversified portfolios and stable income streams from premiums. The predictable nature of proportional treaties like quota share allows reinsurers to manage their own capital effectively and participate in various markets. This interdependency strengthens the global insurance ecosystem.
Types or Variations
While the core concept of a quota share treaty involves a fixed percentage, variations exist primarily in how the quota share is applied or what types of business are included. Common variations might include:
- Specific Quota Share: Applies to a particular line of business or a defined portfolio.
- Excess of Loss Quota Share: A combination where a quota share applies up to a certain loss retention limit, and then excess of loss reinsurance kicks in.
- Adjusted Quota Share: The percentage may be adjusted based on certain factors, although this deviates from the strict definition of a fixed percentage for all risks.
These variations allow for tailored risk management strategies depending on the cedent’s specific needs and the reinsurer’s appetite for risk.

Frequently Asked Questions (FAQs)
What is the main benefit of a quota share treaty for a primary insurer?
The primary benefit is increased underwriting capacity. It allows the insurer to write more business or larger policies than its own capital base would normally permit, by transferring a predetermined portion of the risk and premium to a reinsurer.
How does a quota share treaty differ from excess of loss reinsurance?
In a quota share treaty, the insurer and reinsurer share a fixed percentage of every risk, premium, and loss within the treaty’s scope. In excess of loss reinsurance, the reinsurer only pays claims that exceed a predetermined retention level set by the primary insurer.
Can a quota share treaty cover all types of insurance policies?
Generally, quota share treaties are designed to cover specific lines of business or classes of insurance as defined in the treaty contract. It is not typically used for every single policy an insurer underwrites unless the treaty is extremely broad.
