Managing Property and Liability Risk
| Back to Final Home | Next: Investment Fundamentals → |
Risk Management Overview
Why it matters
- Protects resources/assets from financial loss (accidents, acts of nature, illness/injury, death)
- Preserves the benefits of all your other financial planning
Two major loss types
- Property loss: your stuff gets damaged/destroyed → property insurance
- Liability loss: you’re legally responsible for someone else’s loss → liability insurance
Risk: Key Ideas
Definition
- Risk: uncertainty about an outcome (actual outcome may differ from expected)
Two types of risk
- Speculative risk: possibility of gain or loss (e.g., stocks)
- Pure risk: possibility of loss only (fire, theft, illness, injury)
Important nuance about “chance”
- Very high chance (98%) or very low chance (0.000001%) → low uncertainty
- Moderate chance (e.g., 5%) → higher uncertainty (hard to predict who is affected)
The Risk-Management Process (5 Steps)
Step 1: Identify exposures (sources of risk)
Exposures usually fall into five categories:
- Property loss (house fire, theft)
- Legal liability (car accident, injury to others)
- Illness/injury healthcare costs
- Loss of income due to illness/accident
- Death: family expenses + lost income
Step 2: Estimate risk + potential losses
- Loss frequency: how often a loss might occur
- Loss severity: how big the loss could be
Key idea:
- Don’t focus only on “low frequency.” Focus on severity.
Step 3: Choose a risk-handling method
Four ways:
- Risk avoidance: avoid the activity (don’t skydive)
- Risk retention: accept the risk (small losses you can afford)
- Loss control: reduce frequency/severity (locks, safe driving)
- Risk transfer: transfer to insurer via insurance policy
Step 4: Implement the program
- Select policies/coverage amounts/insurers
- Use the large-loss principle:
- Insure what you can’t afford to lose
- Retain what you can afford
Step 5: Evaluate and adjust
- Review regularly (life changes, new assets, new risks)
- Annual review is common for car ownership exposures
How Insurance Works
What insurance does
- Transfers/reduces pure risk via risk pooling
- Replaces uncertain large loss with a certain smaller cost (premium)
Premium components (high-level)
- Share of group losses
- Reserves for future losses
- Admin costs
- Profit allowance
Policy basics
- Insurance policy: contract between insured and insurer
- Coverage is paid for in advance (annual/semiannual)
Hazards, Insurability, and Indemnity
Hazards (make perils more likely)
Hazard = a condition that increases the probability a peril will occur.
Three hazard types:
- Physical hazard: characteristic of person/property that increases loss chance (e.g., high blood pressure)
- Morale hazard: carelessness/indifference because insurance exists (e.g., stop locking doors)
- Moral hazard: wanting the peril to occur to collect insurance money
Insurance companies may limit/deny coverage when a loss is driven by morale or moral hazard.
Only certain losses are insurable
Insurable losses must be:
- Fortuitous: unexpected timing/magnitude (e.g., lightning fire)
- Financial: measurable money loss (insurers cover $ losses, not inconvenience)
- Personal: suffered by specific individuals/organizations (not society as a whole)
Principle of indemnity
- Insurance pays no more than the actual financial loss.
- Policies also have policy limits (maximum payout). There is no true “full coverage.”
Lowering Premiums (Without Losing the Big Protection)
Deductibles
- Deductible: initial part of a loss you pay before the insurer pays.
- Higher deductible → lower premium.
Coinsurance
- Coinsurance: insured and insurer share losses by percentage (common in health insurance).
- Example: you pay 20%, insurer pays 80%.
Deductible + coinsurance reimbursement
Use this text formula (no special math symbols):
Reimbursement = (1 – coinsurance %) × (Loss – Deductible)
Where:
- Reimbursement = amount insurer pays
- Loss = total loss amount
- Deductible = amount you pay first
- Coinsurance % = share you must pay (for example 0.20 = 20%)
Example
- Deductible = 100
- Coinsurance = 20% (0.20)
- Loss = 1,350
Calculation:
- Loss minus deductible = 1,350 – 100 = 1,250
- Insurer share = (1 – 0.20) × 1,250 = 0.80 × 1,250 = 1,000
- Out-of-pocket = 1,350 – 1,000 = 350
Hazard reduction vs. loss reduction
- Hazard reduction: reduce probability of loss (e.g., nonsmoker discount)
- Loss reduction: reduce severity if peril occurs (smoke alarms, fire extinguishers)
Homeowner’s Insurance (Property + Liability Package)
What it covers (high level)
Homeowner’s insurance bundles:
- Property insurance: dwelling, other structures, personal property/contents, loss-of-use expenses
- Liability insurance: bodily injury/property damage claims from visitors (even “regardless of who was at fault” in many guest-injury situations described in lecture context)
Buying homeowner’s insurance: 4 key questions
- How much coverage to replace the dwelling?
- How much coverage for contents/personal property?
- How much coverage for special limits items (jewelry, money, antiques)?
- How much liability protection is needed?
Replacement-cost requirement (common rule)
- Policies often require you to insure the dwelling for 80% (sometimes 100%) of replacement value (RV).
- Example: RV = 200,000 → required insurance = 160,000 at 80%.
Replacement-cost reimbursement (partial loss)
Use this text formula:
Reimbursement = (Loss – Deductible) × (Insurance carried ÷ (Replacement value × required %))
Where:
- Loss = amount of damage
- Deductible = what you pay first
- Insurance carried = your policy’s dwelling limit
- Replacement value = cost to rebuild the home
- Required % = 0.80 (80%) or 1.00 (100%), depending on policy

| Risk avoidance | Avoid the risk entirely |
| Risk retention | Accept/keep the risk |

Exam Tips
- ✅ Pure vs. speculative risk shows up everywhere (insurance vs. investing).
- ✅ For “Should I insure this?” focus on severity, then apply the large-loss principle.
- ✅ Know the difference between hazard reduction (prevention) vs. loss reduction (damage control).
- ✅ Be able to compute reimbursement with deductible + coinsurance quickly.
Common Mistakes to Avoid
- ❌ Buying insurance based only on low frequency (“it probably won’t happen”) while ignoring severity.
- ❌ Thinking “full coverage” exists (policy limits always exist).
- ❌ Forgetting to subtract the deductible before applying coinsurance.
- ❌ Mixing up morale hazard (carelessness) vs. moral hazard (fraud/incentive).
Practice Problems
Problem 1: Deductible + coinsurance
Given: Loss = 5,000; Deductible = 250; Coinsurance = 20%
Find: reimbursement
Solution:
- Loss – Deductible = 5,000 – 250 = 4,750
- Reimbursement = (1 – 0.20) × 4,750 = 0.8 × 4,750 = 3,800
Problem 2: Large-loss principle (concept)
You have a phone you could replace tomorrow, and a potential liability claim that could bankrupt you.
Which do you insure and why?
Answer: insure the catastrophic exposure (liability) and retain small affordable losses.
