The $3 Million Blanket That Wasn't
Ridgeline Precision Parts operates a single plant built in 1974. A recent appraisal puts building replacement cost at $4.0 million (actual cash value $2.4 million) and contents replacement cost at $1.0 million. The commercial property policy carries a $3.0 million blanket limit on building and contents, an 80% coinsurance clause, no agreed value provision, and a $10,000 per-occurrence deductible. Business income is written separately at a $500,000 limit with a 72-hour waiting period. In March a plating-room fire causes $600,000 of building damage and $250,000 of contents damage, both at replacement cost. Production is down for five months, and the accountant documents $1.1 million of business income loss. The owner's broker tells him, "You carry $3 million, so you're fully covered."
1. Calculate what the insurer pays for the direct property damage and what the insured absorbs. Show the coinsurance mechanics explicitly.

Step 1 - What the clause requires. The coinsurance test compares the limit carried with 80% of the value of the covered property, measured on the policy's valuation basis (replacement cost, given the RC endorsement).
- Building RC $4,000,000 + contents RC $1,000,000 = $5,000,000
- Required limit = 0.80 × $5,000,000 = $4,000,000
- Limit carried = $3,000,000 → underinsured
Step 2 - Penalty factor.
- Factor = 3,000,000 ÷ 4,000,000 = 0.75
Step 3 - Settlement.
- Covered damage = $600,000 + $250,000 = $850,000
- Coinsurance-adjusted = $850,000 × 0.75 = $637,500
- Less $10,000 deductible = $627,500 paid
- Insured absorbs $850,000 − $627,500 = $222,500
Judgment point. The $3 million blanket limit is not a promise to pay any loss up to $3 million. Because $5 million of replacement value exists and only $3 million was reported, the insured is effectively a 25% coinsurer of every loss, partial losses included. With a $4,000,000 limit the payment would have been $840,000 - the reporting decision, not the fire, cost $212,500. The blanket form helps when values shift among locations; it does not cure aggregate underinsurance.
2. Apply the business income coverage to the five-month shutdown and assess whether the limit is adequate. State any assumptions.

Calculation.
- Documented BI loss over five months = $1,100,000
- The 72-hour waiting period removes roughly three days of loss: $1,100,000 ÷ ~150 days ≈ $7,300/day × 3 ≈ $22,000
- Covered BI ≈ $1,078,000
- Limit = $500,000 → payment $500,000
- Insured absorbs roughly $578,000–$600,000, plus any loss beyond the period of restoration
Assumptions. The period of restoration runs five months, no extended period of indemnity applies, and the insured does not continue partial operations that would reduce the loss.
Judgment point. The limit funds about 2.3 months of this single event. A proper limit is built from 12 months of gross earnings plus continuing expenses plus extra expense - not from a round number chosen at binding. Also check whether the insured bought extra expense, dependent-property, or civil-authority coverage; a plating operation with a single plant has high contingent business interruption exposure, and the uninsured $600,000 is a solvency issue for a company of this size.
3. What should the producer recommend now - before, during, and after the claim - and what professional exposure exists?

Immediately.
- Do not promise a coinsurance waiver. Ask the insurer for a mid-term limit increase on a pro rata basis; the coinsurance test is applied at the time of loss, so an increase now helps only future losses.
- Preserve the appraisal and the client's value records; if the insurer disputes the RC figures, the settlement hinges on documentation.
- Put the broker's "fully covered" statement in writing to the agency's E&O carrier. A reasonable insured who relied on that statement to skip a limit review has a plausible errors-and-omissions claim, and notice is time-sensitive.
At renewal.
- Raise the property limit to at least the $4 million required figure, ideally to full $5 million value, and consider agreed value so coinsurance is suspended for the term (usually subject to a current appraisal on file).
- Rebuild the BI limit from a 12-month earnings worksheet, not from premium budget; add extra expense and consider an extended period of indemnity if customers must be requalified.
- Re-test deductibles against cash flow - the insured just demonstrated it cannot absorb $800,000 of uninsured loss.
Judgment point. The fix is not "buy more insurance." It is aligning reported values, the coinsurance clause, the BI limit, and the insured's actual risk-bearing capacity, then documenting the recommendation and the client's decision in the file.
