Valuation Methods

Replacement Cost

Definition: Cost to replace property with new property of similar kind and quality

Requirements:

  • Must insure to at least 80% of replacement value
  • No deduction for depreciation
  • More expensive premium
  • Recommended for most properties

Actual Cash Value (ACV)

Definition: Replacement cost minus depreciation

Formula: ACV = Replacement Cost - Depreciation

When Used:

  • Older properties where replacement cost excessive
  • Lower premium option
  • Some property types mandated by insurers

Coinsurance

What is Coinsurance?

Coinsurance - A provision requiring the insured to carry coverage equal to a specified percentage of property value or face a penalty at loss.

Standard Coinsurance Formula

If Property Underinsured:

Amount Paid = (Amount of Insurance Carried ÷ Amount of Insurance Required) × Loss - Deductible

Example

ItemValue
Building Replacement Cost$1,000,000
80% Coinsurance Required$800,000
Insurance Carried$600,000
Loss Amount$200,000

Calculation:

  • Insurance Required: $1,000,000 × 80% = $800,000
  • Insurance Carried: $600,000
  • Payment: ($600,000 ÷ $800,000) × $200,000 = $150,000
  • Insured receives only $150,000 (plus pays deductible)

Exam Tip: Coinsurance penalties apply when property is underinsured below the coinsurance percentage. Most commercial property policies have 80% coinsurance requirements.

Business Income Coverage

Coverage Provided

Business Income (and Extra Expense) coverage pays:

  • Net income that would have been earned
  • Continuing normal operating expenses
  • Extra expenses to minimize business interruption
  • Coverage during restoration period

Key Features

FeatureDescription
Waiting PeriodTypically 72 hours after loss before coverage begins
Restoration PeriodPays until property restored with reasonable speed
Extra ExpenseCosts to minimize interruption (temporary location, overtime)
Extended PeriodContinues 30 days after restoration to regain business

Business Income Calculation

Business Income = Net Profit + Continuing Expenses

Continuing Expenses include:

  • Payroll (if insured with coverage)
  • Rent or mortgage payments
  • Utilities
  • Insurance premiums
  • Loan payments

Exam Tip: Business income coverage requires 72-hour waiting period and covers loss during the restoration period. Know that extra expenses to minimize interruption are covered.
