Most commercial property insurance includes a limit for "contingent time element" or business interruption.
Therefore, if a business indirectly suffers a loss from an insured peril, (in this case a fire and winter freeze), the insured business can claim back some or all of the loss from the insurer(s), even if the loss does not directly damage any of their properties. If the loss affects one of their suppliers (either a named supplier in the underwriting submission, or even an unnamed / unknown supplier), the property policy can respond.
The example here being a shortage of chips has delayed the delivery of completed vehicles to customers, therefore incurring extra costs (extra expense) for storage and transportation of the vehicles off-site, or even the cancellation of orders. These costs can (and will) be passed on to insurers.
As a result, we are now seeing the limits for such cover being drastically reduced or, in the case of a major vehicle manufacturer I handle, removed completely going forward from renewal (for unknown suppliers). Insurers arguement is that if the customer cannot identify exactly who their suppliers are, there is no way that the risk can be correctly rated (priced) by the insurer.
A similar situation occurred aftere the floods in Taiwan a few years ago. BMW were unable to complete orders of several models of motorbike (K1600 being one) as the factory manufacturing chips for the bike was under water.
