The Nature of Insurance Review

Key Terminology

• Risk: The uncertainty regarding the possibility of loss.

• Peril: The specific event or cause that results in a loss.

• Hazard: A condition that increases the likelihood of a loss occurring.

• Loss: An unintentional decrease in value due to a covered peril.

• Pure Risk: A risk that involves only the possibility of loss, with no chance of gain; this is the only type of risk that is insurable.

• Speculative Risk: A risk that involves the possibility of both loss and gain; these risks are not insurable.

• Adverse Selection: The tendency of higher-risk individuals to seek insurance coverage more frequently than lower-risk individuals.

• Law of Large Numbers: The principle that the larger the number of similar risks insured, the more accurately future losses can be predicted.

The Nature of Insurance

• Definition: In generic terms, insurance is the transfer of risk from one party to another through a legal contract.

• Mechanics of Transfer: The insurer assumes the risk in exchange for the payment of premiums.

• Risk Spreading: Insurance spreads one person's risk of loss among a large number of individuals through the pooling of premiums.

• Policyowner Benefit: When purchasing a policy, the owner obtains a large quantity of coverage in return for a small fee (premium).

• Risk Pooling (Loss Sharing): This fundamental concept distributes risk by spreading the cost of possible losses over a large number of similar (homogeneous) exposure units.

• Requirements for Effective Risk Pooling:

  • Combine a large number of exposure units (people or properties).

  • Ensure exposure units face similar types of risks.

  • Ensure losses that occur are accidental and unintentional.

  • Ensure exposure units are independent of each other.

• Mutual Benefits:

  • Policyholders: Benefit by transferring the financial uncertainty of large losses to the insurance company in exchange for a known premium.

  • Insurance Companies: Benefit by using statistical principles like the law of large numbers to predict losses and set appropriate premiums.

• Example: A life insurance company pools the mortality risk of $10,000$ people of similar age, health status, and risk classification. The company can accurately estimate overall expected losses for the group, even if it cannot predict which specific individuals will incur a loss.

Learning Objectives

Upon completion of this material, students should be able to:

• Explain how risk pooling works in insurance operations.

• Explain how adverse selection affects insurance operations and methods to control it.

• Describe how the law of large numbers enables insurance companies to predict losses.

• Apply the principle of indemnity to insurance situations.

• Define and differentiate between perils, hazards, and losses in insurance contexts.

• Identify the three types of hazards (physical, moral, and morale) and their impact on insurance.

• Distinguish between pure risks and speculative risks in insurance contexts.

• Explain the different methods of handling risk (sharing, transfer, avoidance, reduction, retention, and prevention).

Adverse Selection

• Definition: Broadly defined as "selection against the insurance company." It occurs when high-risk individuals are more likely to seek or maintain insurance coverage than lower-risk individuals, often because they have more accurate information about their own risks.

• Management: To remain profitable, companies use underwriting to evaluate risks and set premiums. A successful operation maintains a balanced distribution including preferred risks (below average), average risks, and a limited number of higher-risk individuals.

• Tools to Minimize Adverse Selection:

  • Thorough underwriting practices.

  • Charging higher premiums for higher-risk individuals.

  • Offering group insurance coverage where the law of large numbers helps balance the pool.

• Life and Health Examples:

  • A person seeking health insurance without disclosing a known serious health condition.

  • An individual with a family history of early death purchasing a large amount of life insurance.

  • A person waiting until they become ill to purchase coverage.

• Protection Methods:

  • Medical underwriting (where permitted).

  • Waiting periods for certain conditions.

  • Preexisting condition limitations.

  • Requiring complete and truthful health information on applications.

Adverse Selection Warning Signs

Law of Large Numbers (Spread of Risk)

• Statistical Principle: States that as the number of similar and independent exposure units increases, the actual loss experience will more closely match the expected loss experience.

• Purpose: Allows insurers to predict future losses with greater accuracy, which is essential for pricing products.

• Key Conditions:

  1. Independence: Each unit must be independent; a fire at one home should not increase the likelihood of fires at other insured homes.

  2. Similarity: Exposure units must face similar types of risks (e.g., a group of homes in the same geographic area built to similar standards).

  3. Large Number: A sufficiently large number is required. Insuring $100,000$ homes provides more predictable results than insuring only $100$ homes.

• Numerical Example: If an insurer covers $100,000$ homes and collects $1,000$ in premiums from each, the fund should cover losses, overhead, and profit. If that insurer only covered $100$ homes and five suffered total losses, the insurer could be bankrupted.

Principle of Indemnity (Indemnification)

• Definition: The goal is to "restore" an insured to the same financial position they were in prior to the loss.

• Core Tenet: An insured shall not profit or gain from their loss; they will not receive more than they lost.

• Application by Policy Type:

  • Indemnity Contracts: Most accident, health, property, and casualty insurance contracts are designed to provide reimbursement for a loss.

  • Valued Contracts: Life insurance policies pay a predetermined amount regardless of the actual loss incurred and are not considered indemnity contracts.

• Exam Terminology: Watch for terms like "make whole" and "restore."

Perils (Causes of Loss)

• Definition: The immediate, specific event that causes a loss.

• Perils by Insurance Line:

  • Property Insurance: Fire, lightning, windstorm, hail, earthquake, and vandalism.

  • Liability Insurance: Negligence (the legal obligation to compensate a third party for harm).

  • Accident and Health: Illnesses and accidents (sudden and gradual onset conditions).

  • Life Insurance: Mortality (premature death).

  • Annuities: Living too long (outliving assets when death is delayed).

Named vs. Open Perils

• Specified (Named) Perils: These policies list the specific perils covered. If a peril is not listed, the loss is not covered. These define covered losses narrowly (e.g., a policy only covering cancer or only covering fire and lightning).

• Special (Open) Perils: These policies cover all direct causes of loss except for those specifically excluded. They stipulate what is NOT covered; everything else is covered (e.g., comprehensive medical insurance and standard life insurance).

Loss

• Definition: An unintended and unforeseen reduction or destruction of financial or economic value.

• Classifications:

  • Direct Loss: Occurs when a person or property is damaged, destroyed, or killed by a peril without any intervening cause. The peril is the "proximate cause."

  • Indirect Loss (Consequential Loss): Results as a consequence of a direct loss.

• Accident vs. Occurrence:

  • Accident: An unforeseen, unexpected, unintended, and sudden event occurring at a specific time and place (e.g., a knee injury from a car accident occurring at $2:00\,PM$ on Friday).

  • Occurrence: Any event that causes a loss, including accidents, injuries, or losses caused by repeated/continuous exposure over time (e.g., a knee replacement needed after years of physical activity).

  • Exam Tip: Every accident is an occurrence, but not every occurrence is an accident.

Hazards

• Definition: A condition that increases the possibility that a peril will occur.

Types of Hazards

• Physical Hazards: Tangible or physical conditions that make a loss more likely. These can be seen, touched, tasted, smelled, or tripped over.

  • Examples: Icy roads, faulty electrical wiring, poor health conditions (high blood pressure, obesity), dangerous occupations (mining, construction), or hazardous hobbies (skydiving).

• Moral Hazards: Arise from the dishonest character of the insured; the insured is more intentional and conscious of participation in wrongdoing.

  • Examples: Lying on an insurance application, faking medical symptoms, insurance fraud, or a business owner disconnecting a sprinkler system to save money.

• Morale Hazards: Arise from a state of mind or indifference to loss because insurance exists; the insured unintentionally creates a loss situation due to carelessness.

  • Examples: A homeowner who rarely changes smoke detector batteries, skipping preventive medical care, or not following a prescribed treatment plan because "insurance will pay anyway."

Risk Classifications and Management

Risk Types

• Speculative Risk: Involves a chance for both loss and gain (e.g., gambling, investing in the stock market). Not insurable.

• Pure Risk: Potential for loss only; no possibility of gain (e.g., injuries, illnesses, death). These are the only types of risk that are potentially insurable.

Elements of Insurable Risk

For a pure risk to be insurable, it must be:

1. Due to Chance (Accidental): Outside the insured's control; randomly selected.

2. Definite and Measurable: The time, place, and amount must be documentable.

3. Predictable: Frequency and severity can be calculated using the law of large numbers.

4. Not Catastrophic: From the insurer's perspective, the exposure must be reasonable (e.g., no war or nuclear disaster coverage).

5. Substantial Units: The number of exposures must be large enough for actuaries to predict loss.

6. Economically Feasible: The premium must be affordable and small in comparison to the loss exposure (e.g., a healthy $45$-year-old male paying less than $500$ per year for a $250,000$ policy).

Insurance Risk Classifications

• Standard Risk: Average potential for loss; insured for a predetermined standard premium.

• Substandard Risk: Poor risk with higher-than-average loss potential; may result in higher premiums, lower benefits, or being declined.

• Preferred Risk: Better-than-average risk with lower loss potential; qualifies for lower-than-average premiums.

Methods of Handling Risk (STARR)

• Sharing: Spreads risk among multiple parties.

  • Examples: Reciprocal insurance companies (inter-insurance exchanges like USAA); coinsurance in medical policies (e.g., an $80\%/20\%$ split where the insurer carries $80\%$ and the insured $20\%$).

• Transfer: Features a legal contract moving risk from one party to another. Buying insurance is the best way to transfer risk.

  • Reinsurance: Method where insurers transfer risk to other insurers to prevent catastrophic loss.

  • Other Examples: Incorporation and hold-harmless clauses.

• Avoidance: Eliminating an activity or condition that exposes a person to loss. The most complete form of risk management (e.g., choosing not to build in a flood zone).

• Reduction: Deliberate actions to reduce the frequency or severity of a loss without eliminating the risk entirely (e.g., installing smoke alarms and sprinkler systems).

• Retention: A conscious strategy to maintain reserves for unexpected expenses.

  • Examples: Deductibles in health or auto insurance ($1,000$ deductible means the insured retains $1,000$ of the risk).

  • Self-Insurance: A planned strategy based on holding reserves (different from "no insurance," which is a refusal to acknowledge risk).

• Loss Prevention: Actions taken to identify, analyze, and control/eliminate loss potential (e.g., de-icing aircraft wings or using masonry instead of wood for construction).

Questions & Discussion

Q: Which principle prevents insurance from being a source of profit?A: The Principle of Indemnity.

Q: Which type of policy is NOT subject to the principle of indemnification?A: Life Insurance (Valued contracts).

Q: What is the difference between an accident and an occurrence?A: An accident is sudden and happens at a specific time/place. An occurrence is broader and can include gradual losses through repeated exposure. Every accident is an occurrence, but not every occurrence is an accident.
