Insurance Study Guide

📖 Core Concepts Insurance – financial protection against loss in exchange for a premium. Policyholder – the buyer of a policy; insured – the person/entity covered. Insurer / Underwriter – company that assumes the risk and issues the insurance policy. Deductible (excess/copayment) – out‑of‑pocket amount the insured must pay before the insurer pays a claim. Risk Pooling – premiums from many insureds are combined to fund the few who experience a covered loss. Insurability Requirements – many similar exposure units, definite loss, accidental cause, calculable probability & cost, affordable premium, and loss not catastrophically large. Legal Doctrines Indemnity – insurer pays only up to the insured’s actual loss/interest. Utmost Good Faith (Uberrima fides) – both sides must disclose all material facts. Insurable Interest – the insured must have a legitimate stake in the property or life. Subrogation – insurer may pursue third‑party recovery after paying a claim. Contribution – multiple insurers share payment of a single loss. Proximate Cause – the dominant cause of loss must be a covered peril. Mitigation – insured must act reasonably to limit loss severity. 📌 Must Remember Combined Ratio = \(\dfrac{\text{Expenses} + \text{Losses}}{\text{Premiums}}\); < 100 % = underwriting profit. Float – premium money held before claims are paid; generates investment income. Condition of Average – if policy limits are below the value of the loss, insurer pays proportionally (under‑insurance). Moral Hazard – insured may become less careful because they are not fully bearing the loss. Reinsurance – transfer of part of an insurer’s risk to another insurer to limit large‑loss exposure. No‑Fault Insurance – each party’s own insurer pays regardless of fault (common in auto). Contribution vs. Subrogation – contribution splits payment among insurers; subrogation lets an insurer chase a third party after paying. 🔄 Key Processes Underwriting & Premium Setting Gather risk data → calculate claim frequency & severity → apply actuarial ratemaking → set premium → decide accept/reject. Claims Handling Claim filed → assigned adjuster → verify coverage → assess loss value → apply deductible & policy limits → authorize payment. Reinsurance Ceding Primary insurer identifies excess risk → negotiates treaty or facultative reinsurance → cedes portion of premium & loss exposure → retains retained risk. Risk‑Management Collaboration Insured implements loss‑control measures → insurer may lower premium or offer discounts → both parties monitor outcomes. 🔍 Key Comparisons Indemnity vs. Benefit Insurance – Indemnity restores loss; benefit pays a fixed amount regardless of actual loss. Co‑insurance vs. Dual Insurance – Co‑insurance shares risk among insurers by design; dual insurance provides overlapping coverage with contribution determining each insurer’s share. Captive vs. Traditional Insurer – Captive is owned by its insured (risk‑retention for a single group); traditional insurers serve the public market. Admitted vs. Non‑Admitted Insurers – Admitted are state‑licensed and must follow local regulations; non‑admitted can write when admitted carriers cannot meet a need but lack regulatory oversight. ⚠️ Common Misunderstandings “Insurance eliminates risk.” It only transfers financial impact; the probability of loss stays the same. Deductible = premium discount – the deductible reduces insurer’s exposure per claim, not the overall premium (though higher deductibles often lead to lower premiums). All losses are covered if a policy exists. Exclusions (e.g., nuclear, war) and proximate cause rules can deny coverage. Reinsurance means the original insurer never pays. Primary insurer still pays up to its retained limit; reinsured portion is reimbursed later. 🧠 Mental Models / Intuition “Insurance = a shared bucket.” Imagine many people pouring water (premiums) into a bucket; only when it rains (a loss) does the bucket pour out to those who get wet. “Moral hazard = safety blanket effect.” The softer the blanket (more coverage, low deductible), the more likely you’ll take risks you otherwise wouldn’t. “Combined ratio < 1 = profit” – think of it as a “spending vs. income” score; stay below 1 to be in the black. 🚩 Exceptions & Edge Cases Condition of Average applies only when the policy is under‑insured relative to the actual value of the property. War/Nuclear exclusions override other coverage; even a “all‑risk” policy can be denied for these perils. Non‑admitted insurers may be used for surplus lines (e.g., hard‑to‑place risks) but policyholder loses certain state protections. Contribution only triggers when policies overlap and are not excluded by a primary policy clause. 📍 When to Use Which Choose Reinsurance when the insurer’s loss‑exposure exceeds its capital or when large‑catastrophe risk threatens solvency. Apply No‑Fault for auto policies where rapid payment is prioritized over fault determination. Select Captive if a large organization wants to retain risk, achieve tax benefits, and customize coverage unavailable in the standard market. Use Dual Insurance when a policyholder seeks redundancy for critical risks (e.g., large property) and is willing to manage contribution calculations. 👀 Patterns to Recognize High‑frequency, low‑severity loss → low deductible, higher premium; low‑frequency, high‑severity loss → high deductible, lower premium. Policy language that is vague → courts interpret against insurer (contra proferentem). Exclusion clause headings (e.g., “War”) → any loss tied to that cause is automatically denied, regardless of other wording. Combined ratio > 100 % repeatedly signals an underwriting cycle entering a loss‑making phase → expect premium hikes. 🗂️ Exam Traps Distractor: “Insurance eliminates the chance of loss.” – Wrong; it only transfers the financial burden. Distractor: “Deductible is the same as a copayment.” – In health policies a copayment is per service; deductible is the total amount before any payment. Distractor: “Subrogation and contribution are interchangeable.” – They address different scenarios (third‑party recovery vs. multiple insurers). Distractor: “All‑risk policies have no exclusions.” – All‑risk still lists specific exclusions (e.g., war, nuclear). Distractor: “A higher premium always means better coverage.” – Premium reflects risk; higher premiums may simply reflect higher expected loss, not broader coverage.
