Self-insurance is a risk management technique wherein an individual or organization sets aside its own money to cover potential future losses, rather than purchasing conventional insurance policies from commercial insurers. It typically involves establishing a separate fund into which funds are deposited on a regular basis. This approach is often chosen to manage high-frequency, low-severity losses.
How Self-Insurance Works
Mathematical Basis of Self-Insurance
Self-insurance can be approached on a mathematical basis, where calculations are made to estimate the amount of money that needs to be set aside periodically. The key elements include:
- Expected Loss Calculation: Estimating the average loss amount based on historical data.
- Funding Policy: Depositing funds regularly into a dedicated self-insurance pool.
- Reserve Establishment: Building a sufficient reserve to cover potential claims.
The formula to calculate the required periodic contribution can be expressed as:
Types of Losses Covered
Self-insurance is practical for:
- High-Frequency, Low-Severity Losses: Such as minor property damage or small claims that occur frequently.
- Predictable Losses: Where the likelihood and magnitude can be estimated with reasonable accuracy.
Special Considerations
Self-insurance may not be suitable for all types of risk due to:
- Insufficient Funds: A significant loss may exceed the funds available.
- Unpredictable Losses: Certain risks might be too unpredictable to self-insure.
Examples
- Businesses: Companies might self-insure for employee health benefits by setting aside money to pay for claims directly.
- Municipalities: Local governments may establish self-insurance pools for workers’ compensation or public liability.
- Consumers: Individuals may self-insure by maintaining an emergency fund to cover minor accidents or damages.
Historical Context
Evolution of Self-Insurance
Self-insurance has been practiced for centuries, particularly among early businesses and governments before the widespread availability of commercial insurance. Over time, the approach has evolved, incorporating sophisticated financial and actuarial techniques to improve efficiency and reliability.
Applicability
Self-insurance is suitable for:
- Organizations with sufficient financial stability and resources.
- Entities that have predictable and manageable risks.
- Businesses seeking to reduce insurance premiums by retaining part of the risk.
