Under a blanket limit the coinsurance test runs against the combined values on the statement of values, not building by building. The amount required is 80 percent of $1,200,000, or $960,000, and only $900,000 was carried, so the insurer pays $900,000 / $960,000 x $250,000 = $234,375. Dividing by the full $1,200,000 of values gives $187,500 and skips the 80 percent step, and multiplying the loss by 80 percent gives $200,000, which misreads the clause as a flat copayment.
