Business interruption: data model

The entities, fields, enumerated values and relationships. The endpoints over them are in Business interruption: API, and the terms used throughout are defined in Insurance concepts.

One entity, businessInterruptionCoverage. It has the shape of a property policy with a financial exposure base added, and it reuses propertyType and propertyPeril from property because the events that stop a business are the events that damage its premises.

Where a property claim is settled against the cost of physical things, this one is settled against accounts: what the business would have earned, less what it did earn, over a defined period.

Selected fields

Entity	Field	Type	What it means
BICoverage	typeBusinessInterruption	enum	Which form of cover this is. Standard business interruption, increased cost of working alone, or contingent loss of profit, which covers an interruption at a supplier or customer rather than at the insured’s own premises
BICoverage	IndemnityPeriod	Number/integer	Days the policy keeps paying after an interruption starts. Not the policy term. A twelve-month policy can carry a 24-month indemnity period, because rebuilding outlasts the policy year. Set too short, the business is underinsured and nobody finds out until the claim
BICoverage	grossAnnualProfit	Number/integer	Profit before the interruption, and the usual basis for the loss calculation
BICoverage	netAnnualProfit	Number/integer	Profit after overheads
BICoverage	grossAnnualTurnover	Number/integer	Revenue before the interruption
BICoverage	totalPayroll	Number/integer	Wage cost, which usually continues while the business is stopped and is therefore part of the loss
BICoverage	fixedExpenses	Number/integer	Costs that run whether or not the business trades: rent, leases, insurance
BICoverage	icwLimit	Number/integer	Increased cost of working. Money spent to keep trading through the interruption, such as temporary premises or an extra shift. Separate from lost profit, because spending it reduces the eventual claim
BICoverage	contingencyLossLimit	Number/integer	Cap where the interruption happened at a supplier or customer instead of at the insured
BICoverage	denialOfAccessLimit	Number/integer	Cap where nothing is damaged and the business still cannot trade because access is blocked
BICoverage	closureByPublicAuthority	Number/integer	Cap where an authority orders the premises shut. The source field name contains spaces and cannot travel as written
BICoverage	limitOfLiability	Number/integer	The most the policy pays across the year
BICoverage	deductible	Number/Float	The excess in days. Cover begins once the interruption has run past this waiting period
BICoverage	deductibleAmount	Number/integer	The excess in money, applied separately
BICoverage	claimsOccurrence	enum (claimsOccurrence)	Claims-occurring or claims-made basis
BICoverage	propertyType	enum (propertyType)	Reused from property
BICoverage	product	ref (Product)	The product this policy was written against
BICoverage	propertyRef	ref (Property)	The premises this cover attaches to. Business interruption only makes sense against a place, and this is the link to it. The property entity is defined in property

What to watch

propertyRef points at a property this module does not create. The premises is created through property and referenced here. There is no property endpoint on this module.

deductible is measured in days, not money. The monetary excess is deductibleAmount, and both can apply.

closure by public authority contains spaces at source and cannot travel as a field name. This page shows closureByPublicAuthority.

IndemnityPeriod is the only PascalCase field on the entity and is kept as written.

Most numeric fields here are typed Number/fFloat at source, with a lower-case f in the middle. Read them all as Number/Float.
