Insurance companies

Insurance companies may be classified into two groups:

* Life insurance companies, which sell life insurance, annuities and pensions products.
* Non-life or general 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 differenttax 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.

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 do 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 to not be available through standard licensed insurers.

Insurance companies are generally classified as either mutual or stock companies. This is more of a traditional distinction as true mutual companies are becoming rare. Mutual companies are owned by the policyholders, while stockholders (who may or may not own policies) own stock insurance companies. Other possible forms for an insurance company include reciprocals, in which policyholders 'reciprocate' in sharing risks, and Lloyds organizations.

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.

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 theflexibility 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.
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.
