Business owner's policy (BOP) explained: a beginner's guide

A business owner's policy is a package. It puts the two coverages nearly every small business needs, property insurance for what it owns and general liability for what it might owe, into a single policy with a single premium, and it adds business income coverage that a business buying the parts separately often forgets. Carriers built it for low-hazard operations such as offices, shops, small restaurants, salons and light service businesses, and they price it below the sum of its parts because the risk is predictable.

The package is convenient and it is also opaque; owners tend to know they have a BOP without knowing what is inside it. This guide opens the package, part by part, explains the two mechanisms on the property side that decide how a claim pays, and lists what the policy does not include so that the gaps are chosen rather than discovered.

The property part: building and business personal property

The property section insures two things. The building, if the business owns it, including permanently installed fixtures, and business personal property, which is everything else the business owns at the premises: furniture, equipment, computers, stock, tenant improvements the business paid for. A tenant insures only the second. Most BOP forms are written on a special, open-peril basis, so any cause of loss not excluded is covered; flood, earthquake, wear and tear, and in some territories wind-driven rain and certain roof losses are the usual exclusions.

Valuation is replacement cost on most BOP forms, which means the carrier pays what it costs to replace the damaged property with new, once it is replaced. Stock is an exception; it is valued at cost, not at selling price. Property away from the premises, in transit or at a job site, is covered only up to a small sublimit, and a business whose equipment travels needs an inland marine floater in addition.

Coinsurance: the mechanism that quietly reduces a claim

Many BOP forms apply a coinsurance clause to the building and contents limits, and it is the single most misunderstood feature in commercial property. The clause requires you to insure the property to a stated share of its full replacement value. If the limit is below that share at the time of a loss, the carrier reduces every partial claim in the same proportion by which you are underinsured. Some BOP forms replace coinsurance with a simpler requirement to insure to full value with a periodic inflation adjustment; check which yours has.

Suppose the contents of a shop would cost $200,000 to replace, the coinsurance requirement is eighty percent, and the owner bought a $100,000 limit to save premium. The required limit was $160,000. A $40,000 fire claim is paid at the ratio of what was carried to what was required, $100,000 over $160,000, so the carrier pays $25,000 less the deductible, not $40,000. Those are round hypothetical figures, and they are the reason the limit on a BOP should come from a real replacement estimate rather than a guess.

Business income and extra expense: paying the bills while closed

The part of a BOP that separates it from a plain property policy is business income coverage. After a covered property loss shuts the business, it pays the net income the business would have earned plus the expenses that continue while it is closed, such as rent, payroll and loan payments, for the period it reasonably takes to repair and reopen. Extra expense pays the added cost of staying open, a temporary location, rented equipment, overtime, when that is cheaper than closing. Most BOP forms write this on an actual-loss-sustained basis for a set number of months rather than to a fixed dollar limit.

Two features matter here. The waiting period, usually a few days, before income coverage begins. And whether the policy includes civil authority coverage, which pays when a government order closes access to the premises because of damage nearby, and utility service interruption, which most forms require as an endorsement. A business that depends on one supplier or one anchor customer should also ask about contingent business income, since the BOP responds to damage at your premises, not theirs.

The liability part

The liability section of a BOP is a general liability policy in all but name: bodily injury and property damage to others from your premises, operations, products and completed work; personal and advertising injury; medical payments to the public; and defence. It carries a per-occurrence limit and an aggregate, and it is subject to the same exclusions, including professional services, pollution, autos, employee injury and most contractual liability. If a landlord or a client asks for a certificate of insurance, a BOP is usually what stands behind it, and additional insured and waiver of subrogation endorsements can be added to it as to a stand-alone liability policy.

Who qualifies, and who does not

Carriers restrict the BOP to classes whose risk fits the package price. The rules vary by carrier, but the pattern is consistent.

• Usually eligible: offices, retail shops, small restaurants and cafes without heavy cooking, salons, small wholesalers, light service businesses, small apartment buildings, and many home-based businesses.
• Usually limited by size: carriers set maximums on square footage, annual sales and building value; beyond them the business moves to a commercial package policy.
• Usually ineligible: contractors with significant field operations, manufacturers, auto dealers and repair shops, bars, businesses with fleets, and anything in a high-hazard class. Some carriers have contractor BOPs for small trades; ask.
• Often excluded from the package but available by endorsement: liquor liability for a restaurant serving alcohol, and professional liability for classes such as salons, opticians or bookkeepers.

What still has to be bought separately

A BOP is not a complete insurance programme. Workers' compensation is a separate policy in every state. Commercial auto for owned vehicles is separate, though hired and non-owned auto liability can often be endorsed onto the BOP for a business with no vehicles. Professional liability, sometimes called errors and omissions, is separate for any business that gives advice or provides a professional service. Flood and earthquake are separate. Cyber liability, employment practices liability and equipment breakdown are frequently available as endorsements on the BOP, and a restaurant should ask specifically about spoilage coverage for a walk-in cooler after a power failure. A commercial umbrella sits above the BOP's liability limits if a contract or the size of the business calls for more.

What decides the premium

The property side is rated on the building and contents limits, the construction type, the age of the roof, wiring, plumbing and heating, the fire protection class of the location, and whether the premises has sprinklers and a central alarm. The liability side is rated on the class of business and its sales or square footage. Claims history and years in business apply to both. Deductibles on the property side are chosen per policy, and raising one is the simplest way to lower the premium. In Arizona and Nevada, building age and roof condition draw particular scrutiny; in Utah and Idaho, freeze and snow load questions come up for older buildings.

How to use this

Find the declarations page and note the building and contents limits, the coinsurance clause or its replacement, the business income basis and months, the liability limits, and the endorsements attached. Then estimate honestly what the contents would cost to replace and how long the business would take to reopen after a fire. If the limits match the estimates and the endorsements cover the gaps listed above, the policy is right and our recommendation is to renew it. If not, we can compare it against the carriers we represent in Arizona, Nevada, Utah and Idaho, at no cost for the analysis.
