What it does
IH 99 28 appears in a carrier forms schedule with a 06 14 edition (titled there "Business Income and Extra Expense Coverage Form"). ISO's cyber incident exclusion IH 99 33 refers to a Coverage Extension – Interruption Of Computer Operations of the Business Income And Extra Expense Coverage endorsement, and the Computer Systems form IH 00 75 lets its virus coverage extend to business income when that coverage applies.
Who needs it
Businesses whose revenue depends on the insured equipment: data centers, imaging centers, broadcasters, contractors with critical equipment.
Quoting and selling notes
Ask for revenue tied to the equipment, period of restoration, and extra expense such as renting replacement equipment. Compare with the rental reimbursement already in IH 00 68.
Before presenting it
Ask the carrier for the specimen of this endorsement and read it with the coverage form it modifies, since the endorsement only changes the provisions it names. Note it on the proposal so the insured knows how it changes the base form.
