Coinsurance, Business Income, and Code Upgrades

Step 1 - Required limit: 80% × $4,000,000 = $3,200,000.

Step 2 - Coinsurance factor: limit carried ÷ required = $2,400,000 ÷ $3,200,000 = 0.75.

Step 3 - Apply to the loss: $40,000 × 0.75 = $30,000.

Step 4 - Deductible: $30,000 − $5,000 = $25,000 paid. (Never more than the limit, and the deductible applies after the penalty.)

The larger lesson: the $15,000 penalty here looks tolerable because the loss is small. On a total loss the insured is a 25% coinsurer of its own building - roughly $800,000 of unfunded exposure - and the policy still only pays $2,400,000.

Options to present:

• Raise the limit to $3,200,000 (simplest, and it fixes the total-loss gap too).
• Agreed value - suspends the coinsurance clause if the insured accepts the submitted value; requires a signed form and periodic revaluation.
• Margin clause - caps recovery per location at a percentage of the reported value; improves the small-loss outcome but does not fix a total loss.
• Reporting form - appropriate only if values genuinely fluctuate and the insured will actually report monthly; a reporting form with bad reports is worse than a coinsurance clause.

Also check the valuation basis: if the $4M figure is stale, both the coinsurance penalty and the limit are wrong at the same time.

Loss of income need:

• 7 months at 100%: 7 × $150,000 = $1,050,000
• 3 months ramping, 35% shortfall: 3 × $150,000 × 0.35 = $157,500
• Total need ≈ $1,207,500

What the policy delivers:

• Period of indemnity is 6 months. Recovery is cut off at 6 × $150,000 = $900,000 - and then the $500,000 limit caps it first.
• Recoverable: $500,000. Shortfall against the actual loss: roughly $707,500, plus any waiting period and the deductible.

Two separate defects, both must be fixed:

1. Limit - $500,000 is less than four months of income. Set the limit on a proper business income worksheet: projected income for the selected period of indemnity plus the ramp-up, not a round number.
2. Period of indemnity - 6 months is shorter than this insured's demonstrated restoration time. Extend to 12 months, 18 if the reconstruction is specialized.

Also address:

• Extra expense - the insured will rent space, subcontract, or pay overtime to shorten the outage. Without extra expense coverage, spending to save income is unreimbursed.
• Ordinary payroll - confirm whether payroll is included; if it is excluded, the insured must lay off staff to avoid a continuing expense, which destroys the ramp-up.
• Contingent BI - if a key customer or supplier is damaged, there is no direct property loss and no recovery.

Ordinance or law: the base property form typically covers little or nothing for the increased cost of construction required by code. Even where a 10% O&L allowance exists, it is 10% of the limit, and here the limit is already understated.

• Add an ordinance or law - increased cost of construction endorsement with a limit set to a realistic upgrade estimate, not a default percentage.
• Confirm whether the endorsement covers demolition cost and the value of the undamaged portion that must be torn down. Losing the undamaged portion is a total-loss exposure the ICC limit alone does not solve.
• Code-triggered upgrades also extend the restoration period - which feeds straight back into the business income period of indemnity.

Vacancy/vacancy permit: with the building unusable for 7 months, the vacancy condition is in play. Unendorsed, vacancy for the stated period (commonly 60 consecutive days) can suspend or reduce coverage for perils like vandalism, glass, water damage, and theft - precisely the losses a dark construction site attracts. Obtain a vacancy permit before the building sits empty, and confirm it applies to the under-construction period.

Other gaps worth raising now:

• Inflation guard - construction costs moved during the claim; the limit should index.
• Debris removal - check whether the sublimit is adequate for a 40,000 sq ft structure.
• Fine arts / valuable papers / EDP - not mentioned in the facts and often forgotten in a fabrication shop.
• Builders risk vs. property - if the insured is doing the rebuild as owner-builder, confirm which form responds during construction to avoid a gap between them.
