What it means
Reinsurance contracts, in which one insurer buys cover from another to protect itself against large losses, usually have a limit. A loss that falls within the layer reduces the remaining cover.
Without a reinstatement clause, the insurer would be exposed to further losses until the next renewal. With the clause, the limit is topped up after a loss, so the buyer has full cover again for the rest of the contract period.
This is vital in catastrophe cover, where a single hurricane or earthquake could be followed by another event. The clause allows a limited number of reinstatements, such as one or two.
The extra premium is called the reinstatement premium. It is normally calculated in proportion to the amount of limit reinstated, and sometimes also in proportion to the time left in the contract.
Some clauses provide free reinstatements for the first one, while others require payment for all. The clause matters for pricing and for accounting.
The insurer must budget for the reinstatement premium that will become due after a loss, which reduces the net benefit of the recovery. Reinsurers include the possibility of reinstatement in their pricing of the cover.
The phrase also appears in other contexts, such as property policies that restore the sum insured after a claim. The principle is the same: coverage is rebuilt, and the policyholder may have to pay for the restored amount.
It is always worth checking the wording on how many reinstatements are allowed and at what price. It is worth comparing the cost of the reinstatement premium with the cost of buying a higher limit up front.
Sometimes a larger single layer is cheaper than a smaller layer with paid reinstatements, and sometimes the opposite is true. Buyers and brokers model both options against the loss scenarios they most fear.
In practice
Real-world examples.
Example
A property insurer has catastrophe reinsurance with one reinstatement. After a hurricane uses half of the layer, the clause restores the limit so that a second storm in the same season is also covered.
Example
A shipping company's marine policy includes a clause that restores the sum insured after a partial loss. It pays an extra premium for the restored amount, calculated pro rata to the loss.
Example
A reinsurer reviews its portfolio and notes that many contracts include free first reinstatements. It increases its base rates to offset the cost of restoring cover without charging extra. The pricing team records the effect so that renewals reflect it consistently.
Formula
Calculation
Reinstatement premium = original premium x (amount of limit reinstated / layer limit)
Some contracts also scale the premium by the time left in the contract, but this example uses the amount only. An insurer buys a $5,000,000 layer of catastrophe cover for an annual premium of $400,000. A storm causes a $2,000,000 loss to the layer, and the clause reinstates the used limit at 100% as to amount. Reinstatement premium = $400,000 x ($2,000,000 / $5,000,000) = $400,000 x 0.40 = $160,000. The reinsurer pays the $2,000,000 loss, and the insurer pays $160,000 to restore the full $5,000,000 of cover.Case study
Seen in the real world.
Marlow Mutual is an illustrative, fictional insurer that writes home policies along a coastline. It bought $10,000,000 of catastrophe reinsurance with two paid reinstatements, and early in the season a storm produced a $6,000,000 loss to the layer.
The reinstatement clause restored the used limit, and Marlow paid a reinstatement premium on the portion used. When a second storm arrived a month later, Marlow still had the full layer available. The illustrative lesson is that the extra premium is cheap compared with being uncovered in the middle of the season.
Marlow's risk committee later modelled a larger single layer with no reinstatements against the existing structure. The comparison showed that the existing layer with paid reinstatements gave the same protection for a lower upfront cost, so the company kept it.
Watch out
Common mistakes.
- Assuming that reinstatement is free, when most clauses require an additional premium for the restored amount.
- Forgetting that the number of reinstatements is limited, when after the last one is used the cover will not be restored again.
- Ignoring the reinstatement premium in budgets, when it can be a large cash outflow right after a loss event.
Questions
People also ask.
What is the difference between reinstatement and renewal?
Reinstatement restores cover during the current contract period, while renewal starts a new contract at the end of it.
Is the reinstatement premium calculated on time?
Sometimes the premium is adjusted for the portion of the contract period remaining, but many catastrophe contracts charge pro rata to amount only.
Why do reinsurers include reinstatement clauses?
They let buyers keep full protection through the period and give the reinsurer additional premium when losses occur, which is a fair exchange because the reinsurer is again exposed to the full limit.
