The period of indemnity is the maximum length of time for which a business interruption insurance policy will pay lost income and continuing expenses after a covered loss. If a fire forces your business to close, the period of indemnity defines the window during which the insurer compensates you for revenue you cannot earn while operations are suspended or reduced. Once that window closes, payments stop even if your business has not fully recovered.
Choosing the right period of indemnity is one of the most consequential coverage decisions you make when buying business interruption insurance.
The clock on the period of indemnity typically starts on the date of the physical damage, not the date you file the claim. It runs until either the business is fully restored to its pre-loss operating condition or the maximum indemnity period expires, whichever comes first.
Your insurer pays your actual loss of income during this period, calculated as the revenue you would have earned minus the variable costs you did not incur because operations were suspended. Continuing fixed costs like rent, loan payments, and essential payroll also qualify for coverage during the period.
Most commercial property insurers offer several standard options. The right choice depends on how long your specific business would realistically take to rebuild and recover revenue.
Most business owners dramatically underestimate how long physical restoration takes. Supply chain delays for materials, contractor availability issues, permitting backlogs, and compliance with current building codes all add time. A twelve-month period of indemnity that seemed adequate when purchased can expire before construction even finishes on a complex commercial property.
The 2024 and 2025 wildfire claims in California demonstrated this repeatedly. Businesses that purchased twelve-month indemnity periods were left without coverage long before their premises were reconstructed, because permitting and materials shortages stretched rebuild timelines well past twelve months.
Physical reconstruction is only part of the problem. Even after you reopen, revenue often takes additional months to return to pre-loss levels as customers have shifted to competitors. An extended period of indemnity endorsement extends coverage beyond the restoration period to address this revenue recovery lag.
Standard extended indemnity periods run 90 to 360 additional days beyond physical reopening. You purchase this as an endorsement on your base policy. Businesses with strong customer loyalty and market position often skip this coverage. Those in highly competitive markets, where customers substitute quickly, benefit most from it.
