Having spent many years as an investigator for an international insurance company-I note the airport had a duty to mitigate the loss by taking immediate action to prevent further damage. Lesley is right on the money with the airport dragging their feet. The building was left open to the elements allowing further water damage and eventually mold. The mitigate clause is standard language in property insurance policy's. The roof needed to be closed to the weather-NAGICO will use this clause in their defense before the court. Insurance companies will pay for mitigation expense. I suspect NAGICO has had a forensic accountant combing the airport books to show the loss of use and profits have been inflated-that's assuming the airport books were in good order. It will be interesting to see the courts ruling in this case.
