They are essentially the same thing. In relation to business interruption insurance, the period of indemnity is generally the period that begins when the physical loss or damage occurs and ends when the property is repaired or replaced and made ready for operations to resume. The period of restoration, as defined by ISO, for example, begins 72 hours after direct physical loss or damage is caused by a covered cause of loss and ends on the earlier of the date the property should be repaired, rebuilt, or replaced with reasonable speed and similar quality or when business is resumed at a new location.
