INSURANCE PRACTICE

Insurance practice Underwriting and rate making The two basic functions in insurance are underwriting and rating, which are closely related to each other. Underwriting deals with the selection of risks, and rating deals with the pricing system applicable to the risks accepted. Underwriting principles Underwriting has to do with the selection of subjects for insurance in such a manner that general company objectives are met. The main objective of underwriting is to see that the risk accepted by the insurer corresponds to that assumed in the rating structure. There is often a tendency toward adverse selection, which the underwriter must try to prevent. Adverse selection occurs when those most likely to suffer loss are covered in greater proportion than others. The insurer must decide upon certain standards, terms, and conditions for applicants, project estimated losses and expenses through the anticipated period of coverage, and calculate reasonably accurate rates to cover these losses and expenses. Since many factors affect losses and expenses, the underwriting task is complex and uncertain. Bad underwriting has resulted in the failure of many insurers. In some types of insurance major underwriting decisions are made in the field, and in other types they are made at the home office. In the field of life insurance the agent's judgment is not accepted as final until the home-office underwriter can make a decision, for the life insurance contract is usually noncancelable, once written. In the field of property and liability insurance, on the other hand, the contract is cancelable if the home-office underwriter later finds the risk to be unacceptable. It is not uncommon for a property and liability insurer to accept large risks only to cancel them at a later time after the full facts are analyzed. The insurance underwriter must tread a thin line between undue strictness and undue laxity in the acceptance of risk. The underwriter's position is not unlike that of the credit manager in a business corporation, in which unreasonably strict credit standards discourage sales but overly weak credit standards invite losses. An important initial task of the underwriter is to try to prevent adverse selection by analyzing the hazards that surround the risk. Three basic types of hazards have been identified as moral, psychological, and physical. A moral hazard exists when the applicant may either want an outright loss to occur or may have a tendency to be less than careful with property. A psychological hazard exists when an individual unconsciously behaves in such a way as to engender losses. Physical hazards are conditions surrounding property or persons that increase the danger of loss. An underwriter may suspect the existence of a moral hazard on applications submitted by persons with known records of dishonesty or when excessive coverage is sought or the replacement value of the property exceeds its value as a profit-making enterprise. Underwriters are aware that fire losses are more likely to occur during business depressions. The underwriter can detect moral hazard in various ways: An applicant's credit may be checked; courthouse and police records may reveal a criminal history or a history of bankruptcy; and other insurance companies can be queried for information when it is suspected that an individual is trying to obtain an excessive amount of coverage or has been turned down by other insurers. The psychological type of hazard can take a number of forms. Some persons are said to be accident-prone because they have far more than their share of accidents, suggesting that unconsciously they want them. It is well known that persons applying for annuities tend to have longer than average lives, and consequently a special mortality table is used for annuitants. Certain types of insanity have to be watched fornotably the impulse to set fires. Physical hazards include such things as wood-frame construction in buildings, particularly in areas where such properties are densely concentrated. Earthquake insurance rates tend to be high where geologic faults exist (as in San Francisco, which is built almost directly over such a fault). Each kind of insurance has its characteristic hazards. In fire insurance the physical hazards are analyzed according to four major factors: type of construction, the protection rating of the city in which the property is located, exposure to other structures that may spread a conflagration, and type of occupancy. In underwriting automobile insurance, the underwriter considers the following factors: the age, sex, and marital status of the driver and members of the driver's household; length of driving experience; occupation; stability of employment and residence; physical impairments; accident and conviction record; extent of use of alcohol and drugs; customary use of the vehicle; age, condition, and maintenance of the vehicle; and records of insurance cancellation or refusal. In some cases tests of emotional maturity are administered. Some underwriters even consider such factors as the school records of student drivers and whether or not driving courses have been taken. The hazards considered in the underwriting of general liability insurance depend on the type of business and the record of the person applying for coverage. In the field of contracting, for example, the underwriter is interested in the type of equipment owned or rented by the applicant; the applicant's losses in the past, attitude toward safe practice, cooperation with building inspectors, and financial position and credit standing; the stability of supervisory employees; and the degree to which the applicant has been a successful contractor in the past.
