Underwriting a sprinklered spinning mill: deductible, capacity and outstanding impairments
Ridgeway Textiles runs a single-site spinning mill and seeks a combined property and business interruption policy: buildings CNY 45m, plant and machinery CNY 30m, stock CNY 12m, and gross profit CNY 18m over a 12-month indemnity period. The five-year loss history is four claims totalling CNY 2.1m: two bearing failures, one sprinkler leak causing CNY 800,000 of water damage, and a waste-store fire extinguished by staff. The sprinkler system was extended to a new warehouse last year but the extension has never been hydraulically tested, and there have been three unresolved impairment notices in twelve months, the longest lasting nine days. The underwriter's model shows a 1-in-200-year loss of CNY 78m with sprinklers working and CNY 140m without. The property treaty gives CNY 60m per-risk capacity, facultative capacity is available but flat, and the insured has grown turnover 18% since the gross profit sum was last reviewed. The broker asks for a 15% rate reduction for the sprinkler upgrade and offers to raise the deductible from CNY 25,000 to CNY 100,000.
1. Set the deductible and the main terms, and explain how the modelled loss and treaty capacity drive your answer.

Start from the loss numbers, not from the broker's offer. The unprotected 1-in-200 loss of CNY 140m exceeds treaty capacity of CNY 60m by CNY 80m; the protected loss of CNY 78m still exceeds it by CNY 18m. Either way, the risk cannot be written on treaty alone. That single fact governs the negotiation.
Deductible. Decline CNY 100,000 as too low; seek CNY 250,000, or CNY 500,000 with a rate credit, because four claims in five years totalling CNY 2.1m is attritional, not catastrophic. Two bearing failures point to maintenance quality, and a higher deductible buys the insured an incentive to improve it. A CNY 25,000 deductible on a CNY 87m value at risk is indefensible.
Terms to impose.
- Hydraulic test and certification of the warehouse extension within 30 days as a condition precedent to liability.
- A protective-safeguards warranty requiring impairment notification and restoration within 24 hours, with a maximum 72-hour suspension of cover.
- An inner sub-limit for sprinkler leakage and water damage (say CNY 1m) given the CNY 800,000 loss already incurred.
- An agreed-value or margin clause on stock and machinery.
Rate. Refuse the 15% reduction. Either hold rate, or grant a modest credit on the tested section while loading for the untested section. Facultative cover for the layer above CNY 60m to at least CNY 140m is essential, at flat pricing, and should be placed before binding.
2. The gross profit sum insured is CNY 18m and has not been reviewed for three years. What is the exposure, and what do you require before renewal?
Read the worked answer
The exposure is average, not coverage. With turnover up 18% and no review, the declared gross profit almost certainly sits well below the required figure. If the audited gross profit is, for example, CNY 24m, the sum insured is 75% of the requirement and the average condition will cut every business interruption claim by 25%. Because the shortfall is invisible in a good year, the insured will not discover it until the first large loss - which is exactly when it hurts.
Before renewal, require:
- Audited financial statements for the last two years, and a calculation of gross profit on the policy's own definition (turnover less uninsured working expenses), not the accountant's profit figure.
- A re-set sum insured based on the correct gross profit plus a margin (typically 110%) for growth between renewal and loss.
- A review of the indemnity period. A single-site spinner needs replacement plant; if spinning frames have a lead time of six to nine months, a 12-month indemnity period leaves little room for rebuild and re-commissioning. Recommend 18 months and price it.
- Consideration of a professional accountant's report or an agreed-value endorsement for the first year to remove the average argument entirely.
Note the professional risk. The three-year gap is a broker issue as well as an underwriting one. If the broker held itself out as reviewing sums insured, an errors and omissions notification may follow - flag it in file notes without comment to the insured, and confirm the position in writing to the client at renewal.
3. The three impairment notices and the sprinkler leakage claim: how do they affect the warranty and the price?
Read the worked answer
What the notices tell you. Three impairments in twelve months, the longest nine days, means the system was materially out of service for a meaningful part of the year. A sprinkler warranty typically requires the system to be in complete working order; a loss occurring while the system was impaired may be excluded or the claim declined altogether. Nine days unprotected at a CNY 140m unprotected PML is not a technicality - it is the difference between a manageable and an unmanageable loss.
The CNY 800,000 leakage claim. Separate the two questions. Leakage from a system in working order is ordinary water damage and is covered, subject to any water-damage sub-limit. Leakage caused by, or occurring during, an impairment is a warranty question. Obtain the impairment logs, the dates, who notified them, the restoration times and whether isolation valves were used. If the loss coincided with an outstanding impairment, coverage is at risk and the claim file must be reviewed before the renewal is quoted.
Underwriting response. Do not simply accept the upgrade as a credit. Either:
- Warrant compliance with a 24-hour restoration rule, with a 72-hour suspension of cover, and verify by requiring monthly impairment reporting; or
- If the insured cannot demonstrate compliance, rate the risk as non-sprinklered and price to the CNY 140m PML, with capacity arranged accordingly.
Also check the maintenance contract for the compressor room and any hot-work controls, since the waste-store fire shows housekeeping is variable.
