Objective Risk Definition And Meaning
What is Objective Risk
Objective risk is defined as the relative variation of actual loss from expected loss. For example, assume that a fire insurer has 5000 houses insured over a long period and, on an average, 1 percent, or 50 houses are destroyed by fire each year. However, it would be rare for exactly 50 houses to burn each year and in some years, as few as 45 houses may burn.
Thus, there is a variation of 5 houses from the expected number of 50, or a variation of 10 percent. This relative variation of actual loss from expected loss is known as objective risk.
Objective risk declines as the number of exposures increases. More specifically, objective risk varies inversely with the square root of the number of cases under observation. Now assume that 5 lacs instead 5000 houses are insured. The expected number of houses that will burn is now 5000, but the variation of actual loss from expected loss is only 50. Objective risk is now 50/5000, or 1 percent.
Objective risk can be statistically measured by some measure of dispersion, such as the standard deviation or coefficient of variation. Since objective risk can be measured, it is an extremely useful concept for an insurance company or a corporate risk manager.
As the number of exposures increases, the insurance company can predict its future loss experience more accurately because it can rely on the “Law of large numbers.” The law of large numbers states that as the number of exposure units increase, the more closely will the actual loss experience approach the probable loss experience. For example, as the number of homes under observation increases, the greater is the degree of accuracy in predicting the proportion of homes that will burn.
