If self insurance is approached as a serious risk management technique, money is set aside using actuarial and insurance information and the law of large numbers so that the amount set aside (similar to an insurance premium) is enough to cover the future uncertain loss.

Self insurance is possible for any insurable risk, meaning a risk that is predictable and measurable enough in the aggregate to be able to estimate the amount that needs to be set aside to pay for future uncertain losses. For a risk to be insurable, it must represent a future, uncertain event over which the insured has no control. Other characteristics which assist in making a risk self-insurable include the ability to price or rate the risk. If the insurable event is one in a large number of similar risks, the aggregate risk can be estimated according to the law of large numbers and the probability of that event occurring in the future can be quantified. Normally, catastrophic risks are not self-insured as they are highly unpredictable and high in loss-value. Catastrophic risks are normally underwritten by the re-insurance or wholesale insurance market. Any risk where the potential loss is so large that no one could afford to pay the market premium required to provide cover would not be commercially insurable. An example is that earthquakes cannot be fully insured against because an earthquake can cause more damage than any insurer or the combined insurance market is willing to risk in total assets. However, captives and self-insurance programmes are often designed to provide for a part of a risk that would be catastrophic to the business concerned, or catastrophic risks that are often commercially uninsurable, such as tobacco litigation liability risks.

Full or exclusive self-insurance is rare, as a combination of self-insurance and commercial insurance usually provides the best cover for the self-insured. Usually the predictable losses of the risk are retained and self-insured, forming a first or “working” layer of cover, and a stop-loss or stop-gap policy is purchased from the commercial insurance market. The commercial insurance market then pays for losses above the specified self-insurance limit per loss, thereby stopping the cost of losses to the self-insured above the retained values. Effectively the losses paid for by the insured before the stop-loss policy pays becomes the deductible layer. Depending on the level at which risks are stopped, commercial insurance cover should become less and less expensive the further away the commercial insurer moves from the working layer of paying claims each year.

A popular and cost-effective form of self-insurance can be found in various types of employee benefits insurance offered by corporations with many thousands of employees. Employee benefits self-insurance programmes are often underwritten by captive insurance companies formed, owned and managed by corporations in both on-shore and off-shore captive domiciles. The reason for this is that hundreds of thousands of employees constitute a large enough risk pool for the corporation to be able to predict and price the risk of losses from benefits offered to employees. In this way, corporations are able to manage their financial exposure to the self-insurance programme without buying commercial insurance.

The idea of self insurance is that by retaining, calculating risks, and paying the resulting claims or losses from captive or on-balance sheet financial provisions, the overall process is cheaper than buying commercial insurance from a commercial insurance company. Cost savings to the self-insured entity are usually realised through the elimination of the carrying-costs that commercial insurers are obliged to pass on to their insurance consumers.

Another example of this is a self-funded health care plan under which a smaller employer helps finance the health care costs of its employees by contracting with a Third Party Administrator (TPA) to administer many aspects of the plan. The employer may also contract with a reinsurer to pay amounts in excess of a certain threshold, in order to share the risk for potential catastrophic claims experience.

Self insurance is less readily available for individuals because individuals rarely gain sufficient cost-savings on small premiums to justify specialised self-insurance captives, interventions and negotiations with insurers. However, many small businesses are now using self-insurance mechanisms such as cell captives and rent-a-captives with considerable success.

More colloquially, the term “self-insured” is used as a euphemism for uninsured.[1]

HOW TO BECOME SELF INSURED [1] How to determine if your company should become self-insured? Add up the premiums your company paid to insurance companies for the past 5 years. Subtract what the insurance companies paid out in losses for the past 5 years. If the insurance company collected more premiums dollars than they paid out, your company is a candidate for becoming self-insured.

Advanced economies account for the bulk of global insurance. With premium income of $1,485bn, Europe was the most important region, followed by North America ($1,258bn) and Asia ($801bn). The top four countries accounted for nearly two-thirds of premiums in 2006. The U.S. and Japan alone accounted for 43% of world insurance, much higher than their 7% share of the global population. Emerging markets accounted for over 85% of the world’s population but generated only around 10% of premiums. The volume of UK insurance business totalled $418bn in 2006 or 11.2% of global premiums.

Life insurance companies, which sell life insurance, annuities and pensions products.
Non-life, General, or Property/Casualty insurance companies, which sell other types of insurance.
General insurance companies can be further divided into these sub categories.

Standard Lines
Excess Lines
In most countries, life and non-life insurers are subject to different regulatory regimes and different tax and accounting rules. The main reason for the distinction between the two types of company is that life, annuity, and pension business is very long-term in nature — coverage for life assurance or a pension can cover risks over many decades. By contrast, non-life insurance cover usually covers a shorter period, such as one year.

In the United States, standard line insurance companies are “mainstream” insurers. These are the companies that typically insure autos, homes or businesses. They use pattern or “cookie-cutter” policies without variation from one person to the next. They usually have lower premiums than excess lines and can sell directly to individuals. They are regulated by state laws that can restrict the amount they can charge for insurance policies.

Excess line insurance companies (aka Excess and Surplus) typically insure risks not covered by the standard lines market. They are broadly referred as being all insurance placed with non-admitted insurers. Non-admitted insurers are not licensed in the states where the risks are located. These companies have more flexibility and can react faster than standard insurance companies because they are not required to file rates and forms as the “admitted” carriers do. However, they still have substantial regulatory requirements placed upon them. State laws generally require insurance placed with surplus line agents and brokers not to be available through standard licensed insurers.

Insurance companies are generally classified as either mutual or stock companies. Mutual companies are owned by the policyholders, while stockholders (who may or may not own policies) own stock insurance companies. Demutualization of mutual insurers to form stock companies, as well as the formation of a hybrid known as a mutual holding company, became common in some countries, such as the United States, in the late 20th century. Other possible forms for an insurance company include reciprocals, in which policyholders ‘reciprocate’ in sharing risks, and Lloyds organizations.

Insurance companies are rated by various agencies such as A. M. Best. The ratings include the company’s financial strength, which measures its ability to pay claims. It also rates financial instruments issued by the insurance company, such as bonds, notes, and securitization products.

Reinsurance companies are insurance companies that sell policies to other insurance companies, allowing them to reduce their risks and protect themselves from very large losses. The reinsurance market is dominated by a few very large companies, with huge reserves. A reinsurer may also be a direct writer of insurance risks as well.

Captive insurance companies may be defined as limited-purpose insurance companies established with the specific objective of financing risks emanating from their parent group or groups. This definition can sometimes be extended to include some of the risks of the parent company’s customers. In short, it is an in-house self-insurance vehicle. Captives may take the form of a “pure” entity (which is a 100% subsidiary of the self-insured parent company); of a “mutual” captive (which insures the collective risks of members of an industry); and of an “association” captive (which self-insures individual risks of the members of a professional, commercial or industrial association). Captives represent commercial, economic and tax advantages to their sponsors because of the reductions in costs they help create and for the ease of insurance risk management and the flexibility for cash flows they generate. Additionally, they may provide coverage of risks which is neither available nor offered in the traditional insurance market at reasonable prices.

The types of risk that a captive can underwrite for their parents include property damage, public and product liability, professional indemnity, employee benefits, employers’ liability, motor and medical aid expenses. The captive’s exposure to such risks may be limited by the use of reinsurance.

Captives are becoming an increasingly important component of the risk management and risk financing strategy of their parent. This can be understood against the following background:

heavy and increasing premium costs in almost every line of coverage;
difficulties in insuring certain types of fortuitous risk;
differential coverage standards in various parts of the world;
rating structures which reflect market trends rather than individual loss experience;
insufficient credit for deductibles and/or loss control efforts.
There are also companies known as ‘insurance consultants’. Like a mortgage broker, these companies are paid a fee by the customer to shop around for the best insurance policy amongst many companies. Similar to an insurance consultant, an ‘insurance broker’ also shops around for the best insurance policy amongst many companies. However, with insurance brokers, the fee is usually paid in the form of commission from the insurer that is selected rather than directly from the client.

Neither insurance consultants nor insurance brokers are insurance companies and no risks are transferred to them in insurance transactions. Third party administrators are companies that perform underwriting and sometimes claims handling services for insurance companies. These companies often have special expertise that the insurance companies do not have.

The financial stability and strength of an insurance company should be a major consideration when buying an insurance contract. An insurance premium paid currently provides coverage for losses that might arise many years in the future. For that reason, the viability of the insurance carrier is very important. In recent years, a number of insurance companies have become insolvent, leaving their policyholders with no coverage (or coverage only from a government-backed insurance pool or other arrangement with less attractive payouts for losses). A number of independent rating agencies, such as Best’s, Fitch, Standard & Poor’s, and Moody’s Investors Service, provide information and rate the financial viability of insurance companies.

Directors and officers liability insurance protects an organization (usually a corporation) from costs associated with litigation resulting from mistakes made by directors and officers for which they are liable. In the industry, it is usually called “D&O” for short.
Environmental liability insurance protects the insured from bodily injury, property damage and cleanup costs as a result of the dispersal, release or escape of pollutants.
Errors and omissions insurance: See “Professional liability insurance” under “Liability insurance”.
Prize indemnity insurance protects the insured from giving away a large prize at a specific event. Examples would include offering prizes to contestants who can make a half-court shot at a basketball game, or a hole-in-one at a golf tournament.
Professional liability insurance, also called professional indemnity insurance, protects insured professionals such as architectural corporation and medical practice against potential negligence claims made by their patients/clients. Professional liability insurance may take on different names depending on the profession. For example, professional liability insurance in reference to the medical profession may be called malpractice insurance. Notaries public may take out errors and omissions insurance (E&O). Other potential E&O policyholders include, for example, real estate brokers, Insurance agents, home inspectors, appraisers, and website developers.

Automobile insurance, known in the UK as motor insurance, is probably the most common form of insurance and may cover both legal liability claims against the driver and loss of or damage to the insured’s vehicle itself. Throughout the United States an auto insurance policy is required to legally operate a motor vehicle on public roads. In some jurisdictions, bodily injury compensation for automobile accident victims has been changed to a no-fault system, which reduces or eliminates the ability to sue for compensation but provides automatic eligibility for benefits. Credit card companies insure against damage on rented cars.
Driving School Insurance insurance provides cover for any authorized driver whilst undergoing tuition, cover also unlike other motor policies provides cover for instructor liability where both the pupil and driving instructor are equally liable in the event of a claim.
Aviation insurance insures against hull, spares, deductibles, hull wear and liability risks.
Boiler insurance (also known as boiler and machinery insurance or equipment breakdown insurance) insures against accidental physical damage to equipment or machinery.
Builder’s risk insurance insures against the risk of physical loss or damage to property during construction. Builder’s risk insurance is typically written on an “all risk” basis covering damage due to any cause (including the negligence of the insured) not otherwise expressly excluded.
Crop insurance “Farmers use crop insurance to reduce or manage various risks associated with growing crops. Such risks include crop loss or damage caused by weather, hail, drought, frost damage, insects, or disease, for instance.”[12]
Earthquake insurance is a form of property insurance that pays the policyholder in the event of an earthquake that causes damage to the property. Most ordinary homeowners insurance policies do not cover earthquake damage. Most earthquake insurance policies feature a high deductible. Rates depend on location and the probability of an earthquake, as well as the construction of the home.
A fidelity bond is a form of casualty insurance that covers policyholders for losses that they incur as a result of fraudulent acts by specified individuals. It usually insures a business for losses caused by the dishonest acts of its employees.
Flood insurance protects against property loss due to flooding. Many insurers in the U.S. do not provide flood insurance in some portions of the country. In response to this, the federal government created the National Flood Insurance Program which serves as the insurer of last resort.
Home insurance or homeowners’ insurance: See “Property insurance”.
Landlord insurance is specifically designed for people who own properties which they rent out. Most house insurance cover in the U.K will not be valid if the property is rented out therefore landlords must take out this specialist form of home insurance.
Marine insurance and marine cargo insurance cover the loss or damage of ships at sea or on inland waterways, and of the cargo that may be on them. When the owner of the cargo and the carrier are separate corporations, marine cargo insurance typically compensates the owner of cargo for losses sustained from fire, shipwreck, etc., but excludes losses that can be recovered from the carrier or the carrier’s insurance. Many marine insurance underwriters will include “time element” coverage in such policies, which extends the indemnity to cover loss of profit and other business expenses attributable to the delay caused by a covered loss.
Surety bond insurance is a three party insurance guaranteeing the performance of the principal.
Terrorism insurance provides protection against any loss or damage caused by terrorist activities.
Volcano insurance is an insurance that covers volcano damage in Hawaii.
Windstorm insurance is an insurance covering the damage that can be caused by hurricanes and tropical cyclones.
