Answer:
The theory of calculating business interruption losses is relatively easy, but the application is very difficult and subjective. Theoretically the insured, based on the most common policy wordings, is entitled to lost profits plus continuing normal operating expenses incurred. Another popular version is lost revenue less saved expenses (or those expenses not necesarily incurred). Ordinary payroll may or may not be covered as a continuing expense based upon the wording of the policy. Insurance companies generally take the position that no depreciation is a continuing expense if the asset is destroyed or idle during the suspension of the business.
