Water stands ankle-deep everywhere. The computers are fried and the contents of all the filing cabinets are soaked. Your own office where most of the records were stored, has the worst damage. The practice carries valuables papers insurance coverage for an amount up to $250,000. it is your responsibility to prepare an estimate of the financial loss so that a claim can be filed with the insurance company. How would you go about it? What would your summary of the losses look like?
