1. On a high layer, the cedant has nothing left to lose above its attachment and can settle fast and dear to preserve a commercial relationship. Which clause corrects that, and what does it cost the cedant?
Claims control, which hands the decision to the reinsurer but can cost the cedant its client relationship
A claims control clause hands the reinsurer the conduct of files above an agreed threshold: it appoints the adjuster, runs the defence, and its consent conditions any settlement. The cedant remains the sole debtor towards its policyholder, but loses control of how the file is resolved. The problem addressed is an asymmetry of interest worth seeing clearly to understand the clause: above its attachment the cedant bears nothing further, so every extra euro of settlement is paid by someone else while the commercial benefit of a quick and generous resolution accrues entirely to it. Control restores the interest of the party that pays, and that is its whole purpose. Its counterpart is heavy and is not written in the treaty: control exercised clumsily costs the cedant its client relationship, and exposes it to the charge of having abandoned a file for which it remains legally answerable both to the policyholder and to its regulator. Finally it must not be confused with the cooperation clause, gentler, which requires information and consultation without ever granting the decision.
Glossary entry · claims-control2. A cedant reports a construction claim eighteen months after the writ, where the clause required thirty days. The arbitral tribunal reduces the recovery by 900,000 euros instead of denying the five million above the attachment. What decided that outcome?
How the sanction is drafted: proportionate to the prejudice caused the reinsurer, not forfeiture of the recovery
A cooperation clause requires the cedant to report without delay losses above a threshold, to pass on documents, and to consult the reinsurer before any significant settlement. It stops short of control: the decision stays with the cedant, which must listen but need not obey. It thus occupies the middle ground between the follow the fortunes clause, which binds the reinsurer to the cedant's decisions almost blindly, and control, which dispossesses it. The problem solved is late information, which deprives the reinsurer of any chance to act usefully, to reserve correctly and to adjust its own retrocession. But what decides the clause's real reach is not the obligation, it is the sanction, and that lies entirely in the drafting. Depending on the words chosen, failure to cooperate brings outright forfeiture of the recovery, or only compensation for the prejudice that failure caused the reinsurer. The first drafting is formidable, since it turns an administrative oversight into a dead loss of several million, and arbitrations on the point are many. Reading a cooperation clause without reading its sanction is therefore to have read only its less important half.
Glossary entry · claims-cooperation3. An industrial site insured for twelve million was never carried on the cession bordereaux, through a configuration failure during a system migration. A fire occurs three months later. On what does the errors and omissions clause turn?
On the line between a good faith clerical error and a withholding that would have changed the reinsurer's decision
An errors and omissions clause provides that a good faith error or oversight in administering the treaty does not deprive the cedant of its cover, provided it corrects on discovery and regularises the corresponding cession premium. It aims at clerical failures: a risk not carried on the bordereau, a cession entry keyed wrongly, an amount transcribed askew. The problem solved is the disproportion between fault and sanction, and it deserves stating in those terms: a treaty covering thousands of policies is run by systems and by people, error is statistically certain over time, and losing cover worth millions over one badly copied line would turn reinsurance into an administrative lottery. The clause never covers bad faith, however, nor adverse selection dressed as error, nor an omission that would have changed the reinsurer's underwriting decision had it been known. That is exactly where all the litigation sits, not on the principle: the line between the protected clerical error and the culpable withholding, which the clause does not cover and which belongs to the good faith owed the reinsurer.
Glossary entry · erreurs-et-omissions4. An industrial group insures its sites through a captive reinsured at ninety percent, and wants certainty that the reinsurer's strength will benefit it should the captive fail. It obtains a cut-through clause. What does its value actually depend on?
On the insolvency law of the likely place of liquidation, which may treat it as an unlawful preference
A cut-through clause breaks the normal privity of a reinsurance contract, which binds only cedant and reinsurer and creates no right in favour of the policyholder. It provides that on the cedant's insolvency the reinsurer will pay the ultimate insured or a named beneficiary directly, up to its share. The problem solved is quality of security: a policyholder writing with a weakly rated carrier, often because a fronting arrangement or a captive requires it, wants certainty that the reinsurer's strength will actually benefit it. Without cut-through that strength is useless to it, since the reinsurance recovery falls into the liquidation estate and is shared among all creditors. The decisive point sits elsewhere than where it is usually sought, and that is the whole purpose of the question: the clause's validity depends not on the law chosen in the contract but on the insolvency law applicable to the failed carrier. Some regimes treat it as an unlawful preference among creditors and set it aside, others allow it. A cut-through clause therefore has value only when backed by a legal opinion on the likely place of liquidation, and more than one jurisdiction may be conceivable for the same carrier, in which case the protection is worth what the least favourable opinion says.
Glossary entry · cut-through5. A liquidator admits one hundred and twenty million of claims and can pay policyholders only fifty five percent. On what basis do reinsurers owe their share, and why does the answer decide the very point of reinsurance?
On the loss admitted in the estate, failing which the cover would vanish just when it is most needed
An insolvency clause states that the reinsurer's obligation is not conditional on the cedant actually paying the loss. In liquidation the reinsurer owes the estate its full share computed on the amount admitted, not on the reduced dividends the liquidator will pay. Without it, the reinsurer could argue its cover indemnifies an outlay the cedant never made, and pay only the distribution percentage. It is worth measuring what that would produce: reinsurance would empty of meaning exactly when it is most needed, and the policyholder's recovery rate would collapse rather than rise. With the clause the effect is the reverse and it is arithmetic: reinsurers pay on the admitted amount, the difference returns to the estate, and the distribution rate paid to policyholders rises accordingly. Reinsurance thus remains a fully recoverable asset of the liquidation, which is its whole reason for existing. Many jurisdictions impose it by statute or by regulator, notably in the United States where its absence simply deprives the treaty of any reinsurance credit on the cedant's balance sheet. It combines, finally, with the offset clause, whose articulation decides what the reinsurer may withhold for unpaid premium.
Glossary entry · insolvency-clause6. A reinsurer owes fourteen million of claims to a cedant in liquidation, which owes it nine million of premium across three separate treaties. What decides whether it pays five million or fourteen?
Insolvency law, which may confine set off to debts arising under the same contract
An offset clause lets cedant and reinsurer discharge only the balance of their mutual debts, premium against claims, commission against recoveries, and often across treaties where the drafting allows. In normal times it simplifies cash flow, which is its visible use; on a failure it becomes decisive, and that is where its real interest lies. A reinsurer owed unpaid premium would rather set off than pay its claims in full and then stand as an unsecured creditor for its premium, a position in which it would recover only the distribution rate. The clause therefore works in practice as security without collateral, which explains the attention it receives in negotiation. Its actual reach does not depend on drafting alone, however: the applicable insolvency law may confine set off to connected debts, meaning those arising under one contract, and refuse cross treaty set off. The gap between the two situations is worth nine million here. This is why serious drafting always states whether the clause operates contract by contract or across the whole relationship, and why its articulation with the insolvency clause is examined in negotiation rather than in litigation.
Glossary entry · offset-clause7. A professional liability treaty carries a five year sunset clause. The cedant's actuary estimates that around seven percent of the line's claims are reported beyond that delay. What must be done with that, and why do regulators watch it?
Reserve it as an implicit retention, failing which the cedant treats a real risk as nil
A sunset clause sets a date beyond which a loss can no longer be presented to the reinsurer, even if it occurred during the cover period and even if it would be covered on the merits. The period runs from expiry of the treaty and typically spans three to ten years. The problem solved is the indefinite tail: a losses occurring treaty on a long tailed line leaves the reinsurer exposed to notifications that may arrive fifteen or twenty years later, tying up reserves and capital with no closing horizon and preventing any underwriting year from being shut. By bounding the reporting window, the clause lets an account be closed. Its counterpart falls entirely on the cedant, and that is the point to keep: it alone retains losses reported out of time, including those whose lateness is in no way its doing, since a policyholder who discovers late has committed no fault. That retention is real, quantifiable from the line's distribution of reporting delays, and must be reserved as such. This is precisely why regulators and auditors watch it: the risk is not that the clause exists, it is that it should be treated as costing nothing.
Glossary entry · sunset-clause8. A motor bodily injury claim occurring in 2012 settles in 2026 for 4.2 million. The attachment was 1 million in 2012 and the chosen index has risen thirty eight percent. What does indexation correct, and what does it apply to?
The erosion of the attachment in real terms, which would transfer a growing share of losses to the reinsurer with no premium
An index clause indexes the attachment, and sometimes the limit, of a non proportional treaty to a price or wage index, so that the economic split between cedant and reinsurer stays the one negotiated. The mechanism it corrects is silent and is best understood by following it: without indexation an attachment set at one million protects a little less in real terms each year, so the reinsurer is handed a growing share of losses that have not in fact worsened, and with no premium in return. The transfer is real, it is free, and nobody decided it. The problem is sharpest on long tailed lines, liability, motor bodily injury, construction, where twelve to fifteen years may separate occurrence from final settlement: in the case described the indexed attachment moves from one million to 1.38 million, and the reinsurer's share from 3.2 to 2.82 million on a single file. The clause comes in three forms worth telling apart: full indexation, at the whole pro rata of the index drift; indexation with a franchise, operating only beyond a drift threshold often set at ten or twenty percent; and capped indexation. It is the most technical negotiating point of a liability renewal, and the one whose financial effect is most often understated on both sides of the table.
Glossary entry · clause-de-stabilite9. A New York cedant places a layer with foreign reinsurers. Two of them refuse the service of suit clause, and it must post collateral of one hundred percent of their share. What links the clause to that requirement?
The regulator conditions reinsurance credit on a workable route to enforcement, which the clause supplies and collateral replaces
A service of suit clause binds the reinsurer, should it fail in its obligations, to submit to a jurisdiction chosen by the cedant and to appoint there an agent authorised to receive process. It is American in origin and answers a very concrete difficulty: getting a reinsurer established abroad to appear, then enforcing a judgment against it, can take years and cost more than the receivable. By naming a forum and an agent in advance, the clause removes most of that obstacle. The link with collateral rests on a substantive regulatory requirement, and that is what the question asks you to see: a cession is recognised on the cedant's balance sheet, as reinsurance credit, only if the receivable from the reinsurer is genuinely recoverable. A workable route to enforcement is one proof of that, full collateral is another, and the absence of the first makes the second a requirement. One last drafting point is worth knowing, since it is easily neglected: the articulation with an arbitration clause demands care. Well drafted, the two coexist, arbitration settling the merits while service of suit serves to compel arbitration and then to have the award recognised; badly drafted, they cancel each other and open a preliminary dispute over the forum, which is exactly what they were meant to prevent.
