History of insurance

In some sense we can say that insurance appears simultaneously with the appearance of human society. We know of two types of economies in human societies: natural or non-monetary economies (using barter and trade with no centralized nor standardized set of financial instruments) and more modern monetary economies (with markets, currency, financial instruments and so on). The former is more primitive and the insurance in such economies entails agreements of mutual aid. If one family's house is destroyed the neighbours are committed to help rebuild. Granaries housed another primitive form of insurance to indemnify against famines. Often informal or formally intrinsic to local religious customs, this type of insurance has survived to the present day in some countries where modern money economy with its financial instruments is not widespread.
Turning to insurance in the modern sense (i.e., insurance in a modern money economy, in which insurance is part of the financial sphere), early methods of transferring or distributing risk were practised by Chinese and Babylonian traders as long ago as the 3rd and 2nd millennia BC, respectively. Chinese merchants travelling treacherous river rapids would redistribute their wares across many vessels to limit the loss due to any single vessel's capsizing. The Babylonians developed a system which was recorded in the famous Code of Hammurabi, c. 1750 BC, and practised by early Mediterranean sailing merchants. If a merchant received a loan to fund his shipment, he would pay the lender an additional sum in exchange for the lender's guarantee to cancel the loan should the shipment be stolen or lost at sea.

Claims

Claims

Claims and loss handling is the materialized utility of insurance; it is the actual "product" paid for. Claims may be filed by insureds directly with the insurer or through brokers or agents. The insurer may require that the claim be filed on its own proprietary forms, or may accept claims on a standard industry form, such as those produced by ACORD.
Insurance company claims departments employ a large number of claims adjusters supported by a staff of records management and data entry clerks. Incoming claims are classified based on severity and are assigned to adjusters whose settlement authority varies with their knowledge and experience. The adjuster undertakes an investigation of each claim, usually in close cooperation with the insured, determines if coverage is available under the terms of the insurance contract, and if so, the reasonable monetary value of the claim, and authorizes payment.
The policyholder may hire their own public adjuster to negotiate the settlement with the insurance company on their behalf. For policies that are complicated, where claims may be complex, the insured may take out a separate insurance policy add on, called loss recovery insurance, which covers the cost of a public adjuster in the case of a claim.

Underwriting and investing

Underwriting and investing

The business model is to collect more in premium and investment income than is paid out in losses, and to also offer a competitive price which consumers will accept. Profit can be reduced to a simple equation: Profit = earned premium + investment income - incurred loss - underwriting expenses.
Insurers make money in two ways:

1. Through underwriting, the process by which insurers select the risks to insure and decide how much in premiums to charge for accepting those risks;
2. By investing the premiums they collect from insured parties.

The most complicated aspect of the insurance business is the actuarial science of ratemaking (price-setting) of policies, which uses statistics and probability to approximate the rate of future claims based on a given risk. After producing rates, the insurer will use discretion to reject or accept risks through the underwriting process.
