Chp 7: Ratemaking Flashcards
What rating factors are commonly used in the process of ratemaking? (8)
- Age, Gender, and Marital status
- Driving Experience
- Driving Record
- Other regular drivers
- Territory and distance driven annually
- Vehicle usage
- Vehicle description
- Coverage
Age, Gender and Marital status of applicant
Historically have been used as rating factors but pressure has been growing to using them because they are considered unfair and discriminatory.
However, statistics indicate a definite relationship between these factors and loss frequency. Examples include:
-Single male drivers under 25 traditionally have worst driver records, but once they are married, it tempers their driving habits because they have to worry about others well being
-Young women historically have better driving records
Can be discriminatory as good drivers may be charged higher premiums as a result of the class of individuals they are catogorized with
Driving experience
Is the number of years a driver has been licensed. Usually newly licensed drivers are allowed credit for 3 years driving experience if they show that they have completed an approved driver training course.
Driving record
Measures how many accidents and traffic violations (of any kind except parking) the applicant has had.
Includes any driving convictions in the past 3 years and any suspensions during the past 6 years
Other regular drivers
Similar details as described above are required of other drivers who regularly use the vehicle, as is the percentage of use by each person per vehicle
Territory and Distance driven annually
Regularity and distance driven affect the extent to which a vehicle is exposed to loss. The more it is on the road, the greater its chance of being involved in an accident.
Where the automobile is driven also has an impact on the number and types of accidents, or losses it is exposed to thus affecting the rates
Give examples of different types of loss exposures in different parts of the country. (8)
- In congested urban areas - tend to be more rear end collisions and fender benders, but are less likely to be totalled
- Long distance highway driving more likely to result in accidents at high speed or multiple vehicle pile ups with severe injuries, deaths, and heavy damage or total loss to vehicle
- Driving on country roads may result in single vehicle accidents because of speed, poor road conditions, and visibility
- Gravel areas are hard on windshields and lights
- Some areas are more prone to summer hailstorms which can damage cars (Alberta)
- Pedestrian accidents more common in congested areas
- Vehicle fire more common in remote areas
- Vehicle theft more common in congested areas, as it is easier to steal when your by a heavily populated area and where you can get lost in a crown
Vehicle Usage
Is the vehicle used for business purposes or personal use?
Exposures can very when cars are used for different purposes. Some purposes require the car to be on the road more, or to be used in more hazardous areas, or to be driven by multiple drivers
Vehicle description
includes the year, make, model, and serial number of the vehicle (VIN)
Many newer models have safety technology systems which can reduce the likelihood of collisions, resulting in lower premiums.
Where as other models are known to be more susceptible to certain types of damage as a result of their construction, therefore higher rates are charged
Coverage
When insureds request more extensive coverage, higher premium will be charged, less coverage = less premium
If insured requests lower deductible, the premium will be higher than if insured requests higher deductible.
Statistical and Actuarial rating- What is the law of large numbers and how does it relate to rating?
The mathematical premise that states that the degree of uncertainty is reduced as the number of events increases
The law of large numbers can be applied to individual risks by keeping statistical loss records on a large number of such risks
What are the components of an automobile insurance rate? (2)
1) Pure premium- Portion of the total premium that is needed to pay the expected losses
2) Expense loading - the part of the premium rate that represents the costs to the insurer of producing and maintaining the policy. It is added to the pure premium.
What is included in the expense loading costs? (5)
- Acquisition costs- costs of putting business on the books and acquiring premium (Includes commission and cost of insurers sales structure)
- Processing and servicing costs (Administration)
- Insurance premium taxes
- Contingencies (Catastrophes, extra large losses, and reinsurance costs)
- Profit
Statistical body and data collection
All private insurers who write business in Canada must record and file automobile experience data to comply with the requirements of the automobile statistical plans prescribed by the superintendents of insurance.
The General Insurance Statistical Agency (GISA) acts as the statistical agent on behalf of Alb, NB, NL, NS, Ont, PEI, Yukon, NT, NWT
In Quebec, the Groupement des assureurs automobiles (GAA) is the appointed statistical agent
GISA prepares exhibits for the Automobile statistical plan (ASP)
What is the Automobile Statistical Plan (ASP)? And what information do the exhibits present?
- A collection of statistical information that all automobile insurers who write business in Canada must record and file as prescribed by the superintendent of insurance. Commonly known as the green book.
The exhibits present historical insurance statistics for the following classes of vehicles:
-Individually rated (individually rated vehicle not on fleet policy)
-Fleet rated on per vehicle bases
-Fleet rated on a bulk basis
-Miscellaneous (policies other than fleet or individual)
-Private passenger vehicles
-Commercial vehicles
-Public automobiles (ambulances, public buses, taxis, etc)
-Garages, manufacturers, and auto dealers
-Other personal use vehicles (Motorcycles, ATV’s, etc) - Driver policies and NOA insurance policies
