2.5 Valuation Methods, Coinsurance & Loss Settlement Formulae

Valuation Methods & Coinsurance

Once an adjuster determines a loss is covered, they must determine how much to pay. This is governed by the Valuation clauses in the policy. Understanding the math behind loss settlement is one of the most critical skills for passing the exam and working in the field.

Primary Valuation Methods

Actual Cash Value (ACV)

Actual Cash Value is the foundational method of property valuation. It reinforces the principle of indemnity (making the insured whole, but not better off). ACV takes into account the age, wear and tear, and obsolescence of the item.

The standard ACV Formula: ACV = Replacement Cost (RCV) - Depreciation

• Replacement Cost (RCV): The cost to buy a brand-new item of like kind and quality today, at current market prices.
• Depreciation: The loss of value due to age, use, wear and tear. Usually calculated based on the item's expected life span.

Example: An insured bought a television 5 years ago. A fire destroys it. A brand-new TV of the exact same size and quality today costs $1,000 (RCV). TVs have a life expectancy of 10 years, so it has depreciated by 50% ($500). ACV = $1,000 (RCV) - $500 (Depreciation) = $500 payout.

Replacement Cost Value (RCV)

Replacement Cost is paying the cost to replace the damaged property with new property of like kind and quality, without any deduction for depreciation.

• This goes against strict indemnity, as the insured gets a new item for an old one. Therefore, it requires an endorsement or is built into specific policies (like HO-3 Dwelling coverage).
• The Holdback: Insurers usually pay the ACV first. The insured only receives the "recoverable depreciation" (the difference between ACV and RCV) after they actually repair or replace the property and submit receipts.

Functional Replacement Cost

Used when the property is older or uses obsolete materials. It pays to repair or replace the damaged property with less costly, but functionally equivalent, modern materials. (e.g., replacing lath-and-plaster walls with drywall).

Agreed Value (Valued Policy)

The insurer and insured agree on the value of the property at the time the policy is written. If a total loss occurs, the insurer pays the agreed amount, regardless of depreciation or market fluctuations. Common in fine arts, antiques, and classic cars.

Valued Policy Laws

Many states have "Valued Policy Laws" which apply specifically to real property (buildings) destroyed by fire (and sometimes other specified perils like tornado). These laws state that if a building is a total loss, the insurer must pay the full face amount of the policy limits, regardless of what the ACV or Replacement Cost was at the time of loss.

The Coinsurance Clause

The coinsurance clause is a mechanism designed to encourage policyholders to carry insurance close to the full value of the property. It is most prevalent in commercial property policies, but the concept (often called the "80% rule") exists in homeowners policies as well.

Insurers price their premiums assuming a building is insured to value. Most losses are partial. If a $1,000,000 building only has $200,000 of insurance, the insurer is not collecting enough premium for the risk of paying frequent $50,000 partial losses.

If the insured fails to carry the required amount of insurance, they become a "co-insurer" and must share in the loss penalty.

The Coinsurance Formula

To determine the claim payout when a coinsurance penalty applies, use this formula (memorize it!):

(Did Carry / Should Carry) x Loss Amount = Settlement

• Did Carry: The limit of insurance actually purchased by the insured on the policy declarations.
• Should Carry: The minimum amount of insurance required. Calculated as: Value of the Property at Time of Loss x Coinsurance % Requirement.

(Note: The settlement is always subject to the policy limit. The insurer never pays more than the limit of liability, regardless of the formula).

Coinsurance Math Problem: Step-by-Step

Let's walk through a classic exam scenario.

The Facts:

• Building Value at time of loss: $500,000
• Coinsurance requirement in policy: 80%
• Insurance limit purchased (Did Carry): $300,000
• Amount of loss (Fire damage): $100,000
• Deductible: Ignore for this formula unless asked.

Step 1: Calculate the "Should Carry" amount.

• $500,000 (Value) x 0.80 (Requirement) = $400,000 (Should Carry)
• The insured was required to carry at least $400,000 to avoid a penalty.

Step 2: Compare "Did" to "Should".

• Did Carry ($300,000) is less than Should Carry ($400,000). A penalty applies.

Step 3: Apply the Formula.

• ($300,000 / $400,000) x $100,000 Loss = Settlement
• (0.75) x $100,000 = $75,000

Result: The insurer pays $75,000. The insured absorbs a $25,000 coinsurance penalty because they were underinsured.

The Homeowners "80% Rule"

In HO-2 and HO-3 policies, the coinsurance concept is applied to Coverages A (Dwelling) and B (Other Structures).

If the insured carries coverage equal to at least 80% of the dwelling's replacement cost at the time of loss, partial losses are paid at full Replacement Cost (no depreciation applied).

If the insured carries less than 80%, the insurer will pay the greater of:

1. The Actual Cash Value (ACV) of the damaged part of the building.
2. The amount calculated using the coinsurance formula: (Did Carry / Should Carry) x Loss.
