Study guide
Every question on the property and casualty exam ultimately rests on a shared vocabulary: what risk is, how insurers measure a loss, and who owes what when someone is legally responsible for harm. This chapter builds that foundation, from the difference between a peril and a hazard to the way liability limits and damages are structured.
Risk, Peril, and Hazard
Risk is uncertainty about loss. Insurance deals only with pure risk, where the outcomes are loss or no loss, such as the chance a house burns. Speculative risk, like buying stock or opening a restaurant, includes the possibility of gain and is not insurable. A peril is the actual cause of loss: fire, windstorm, theft, collision. A hazard is anything that increases the likelihood or severity of a loss from a peril, and the exam expects you to distinguish three types. A physical hazard is a tangible condition, like frayed wiring, an unfenced swimming pool, or icy front steps. A moral hazard arises from dishonesty, such as an insured who exaggerates a claim or deliberately sets a fire to collect insurance. A morale hazard, sometimes called an attitudinal hazard, is carelessness or indifference because insurance exists, like leaving the car unlocked with the keys inside because theft is covered. Try a quick drill: Marta stores oily rags next to her furnace. The rags are a physical hazard; the fire they could start is the peril; the uncertainty about whether her shop will burn is the risk. Insurers make pure risk manageable through the law of large numbers, the principle that as the number of similar exposure units grows, actual losses come closer to predicted losses, allowing accurate premium pricing. That is why insurers want large pools of homogeneous exposures rather than a handful of unique ones.
Insurable Interest, Indemnity, and Loss Valuation
Insurable interest means the policyholder would suffer a genuine financial loss if the insured event happened. In property and casualty insurance, insurable interest must exist at the time of loss; without it, a policy would be a wager. Ownership, a mortgage, a lease, or lawful possession can all create insurable interest. Indemnity is the companion principle: insurance should restore the insured to the approximate financial position held before the loss, no better and no worse. The insured should not profit from a claim. Valuation methods put indemnity into practice. Actual cash value, or ACV, is generally defined as replacement cost minus depreciation, though courts in some states apply a broader fair market or broad evidence standard. Replacement cost pays the amount needed to replace damaged property with new property of like kind and quality, with no deduction for depreciation. Consider a ten-year-old roof that would cost 20,000 dollars to replace and has lost half its useful life: ACV pays about 10,000 dollars, replacement cost pays 20,000 dollars. Stated value and agreed value approaches are used for hard-to-price property such as antiques or classic cars. Under an agreed value policy, the insurer and insured settle on the property's worth when the policy is written, and that amount is paid at a total loss, avoiding disputes after the fact. Functional replacement cost, used for older buildings, pays to replace with less costly modern materials that serve the same function, such as drywall in place of plaster.
Coinsurance, Insurance to Value, and Direct Versus Indirect Loss
Most property losses are partial, so an owner might be tempted to insure a building for far less than its value and still collect in full on small claims. Coinsurance discourages this underinsurance. A coinsurance clause, commonly 80 percent for buildings, requires the insured to carry coverage equal to at least that percentage of the property's value at the time of loss. If the insured falls short, the insurer pays only a proportion of the loss, calculated by the formula: amount carried divided by amount required, multiplied by the loss, minus any deductible. Suppose Devon owns a building valued at 500,000 dollars with an 80 percent clause, so 400,000 dollars of coverage is required. He carries only 300,000 dollars and suffers a 100,000 dollar fire loss. The insurer pays 300,000 over 400,000, or three quarters, of the loss: 75,000 dollars before the deductible. Devon absorbs the rest as a penalty for underinsuring. The exam also tests the distinction between direct and indirect loss. A direct loss is physical damage to property from a covered peril, like the fire damage itself. An indirect loss, also called a consequential loss or loss of use, flows from the direct loss: lost rental income while the building is repaired, the cost of a hotel while a home is uninhabitable, or a business's lost profits. Property forms treat these separately, with time element coverages such as business income and additional living expense responding to the indirect side.
Negligence, Liability, and Damages
Casualty insurance responds when the insured becomes legally liable to someone else, and most liability arises from negligence: the failure to exercise the degree of care a reasonably prudent person would use in the same circumstances. To recover, an injured party generally must show four elements: a duty owed, a breach of that duty, actual injury or damage, and proximate cause, meaning an unbroken chain between the breach and the harm. Some liability attaches without proving negligence. Strict liability applies to inherently dangerous activities and to defective products, so a manufacturer can be liable even if it used reasonable care. Absolute liability is imposed by law regardless of fault; workers compensation is the classic example, since employers owe benefits for workplace injuries without any showing of negligence. Vicarious liability makes one party responsible for another's conduct, such as an employer answering for an employee acting within the scope of employment, or, in many states, a parent for a minor driver. Damages come in two broad categories. Compensatory damages reimburse the injured party and include special damages, the measurable out-of-pocket costs like medical bills and lost wages, and general damages for intangible harm like pain and suffering. Punitive damages punish egregious conduct rather than compensate, and whether liability insurance may pay them varies by state; some states prohibit insuring punitive damages as against public policy. Liability policies are written to cover the sums the insured becomes legally obligated to pay as compensatory damages, plus the cost of defending the insured.
Limits of Liability, Binders, and Endorsements
A limit of liability is the most the insurer will pay, and the exam tests several structures. Split limits state separate maximums for bodily injury per person, bodily injury per accident, and property damage per accident. Limits of 100/300/50 mean 100,000 dollars per injured person, 300,000 dollars total bodily injury per accident, and 50,000 dollars for property damage. If two people are each awarded 120,000 dollars, the per-person cap holds each recovery to 100,000 dollars even though the combined 200,000 dollars is well under the 300,000 per-accident limit. A combined single limit, or CSL, provides one pool, such as 300,000 dollars, that applies flexibly to any mix of bodily injury and property damage in one occurrence. An aggregate limit caps what the insurer pays for all losses during the policy period; commercial general liability policies carry aggregates, and once exhausted, no further claims are paid until the limits reset at renewal. Two transactional tools round out the basics. A binder is temporary evidence that coverage is in force before the policy is issued, commonly effective for a short period and often oral or written; it can be terminated when the insurer issues or declines the policy. An endorsement, called a rider in life insurance, is a written amendment that adds, deletes, or modifies coverage, and its terms override conflicting language in the base policy. Producers should remember that a binder obligates the insurer immediately, which is why binding authority is granted carefully in agency agreements.

- — The statistical principle that actual losses approach expected losses as the number of similar exposure units increases, enabling accurate premium pricing.
Exam tips
- When a question describes a person or condition, sort it fast: cause of loss is the peril, anything increasing the chance of loss is the hazard, and dishonesty points to moral hazard while carelessness points to morale hazard.
- Memorize the coinsurance formula, did over should times the loss, then subtract the deductible; exam questions almost always make the insured underinsured so you must apply the penalty.
- With split limits, apply the per-person bodily injury cap to each claimant first, then check the per-accident total; many answer choices bait you into paying the full aggregate.
- Remember that property insurable interest is required at the time of loss, and that indemnity means no profit, which is why ACV deducts depreciation.
- Absolute liability means no fault needs to be proven (workers compensation), strict liability attaches to dangerous activities and defective products, and vicarious liability transfers responsibility to a supervising party.
