Turn a dense placement record into a traceable map of risk, money, claims and change
A reinsurance treaty slip compresses a portfolio risk transfer into technical clauses, defined terms, figures and endorsements. Careful English lets a reader reconstruct the deal without mistaking a market label for a guaranteed recovery.
Choose the route closest to your task, or read straight through for the complete system.
A treaty slip can look short beside a full policy wording, yet every line may point to definitions, schedules, underwriting information, market rules or later endorsements. The skilled reader slows down. First establish the document and its authority; then map the portfolio, trigger, layer and economics; finally follow claims, accounts and amendment routes.
Did You Know? A subscription placement can show more than 100 per cent in written lines before the market signs the order down to final participations. That is why an attentive reader distinguishes an underwriter’s offered share from the share finally accepted. The discovery is useful beyond insurance: a provisional response, an accepted allocation and an executed commitment are different states, even when they appear in the same file.
Singapore readers should use current supervisory material from the Monetary Authority of Singapore. International readers can use the IAIS Insurance Core Principles for regulatory context. London-market readers may also consult the Lloyd’s Market Association material on the Market Reform Contract and International Underwriting Association contract-certainty resources. These sources explain systems; the executed contract still controls the private relationship.
This guide uses educational examples. It does not place cover, assess security, calculate an actual recovery, interpret law or recommend a transaction. Those tasks belong to authorised professionals using the complete current file.
English matters because reinsurance joins underwriting, actuarial analysis, broking, finance, claims and law. Clear definitions and controlled cross-references allow those specialists to challenge the same evidence. Other languages can support understanding and negotiation; the goal is a shared, verified contract record, not the elevation of one language over another.

A reinsurance treaty slip is a compact placement record for a continuing class or portfolio of insurance business. It can summarise the risk transfer that a cedant proposes and participating reinsurers accept, but its contractual effect depends on the full document set, signatures, market practice and governing law.
Treaty reinsurance differs from facultative reinsurance because it generally responds to a defined portfolio or class rather than one individually offered risk. The word treaty therefore changes the first reading question from “Which insured asset?” to “Which stream of underlying business, written by whom, enters the agreement under what rules?”
Use the MAS insurance regulation overview for Singapore’s regulatory frame, and the IAIS Insurance Core Principles for international supervisory context. Neither source interprets a private contract.
A cover page may say “Property Catastrophe Excess of Loss Treaty”. That label suggests a structure, not a complete answer. The reader must still find the reinsured business, territorial reach, event language, retention, layer, exclusions, period and order signed.
- Name cedant, broker and reinsurers.
- Record document version and status.
- Identify treaty class and type.
- Locate signatures or order information.
- List every incorporated attachment.
A slip is not a guarantee of recovery and this guide is not underwriting or legal advice. Exact wording, endorsements and applicable law control.
Students practise genre recognition: a label gives orientation, while authority, scope and document status determine what the text can prove.
Make a two-column placement note for Know what a treaty slip is. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
The same organisation can appear as cedant, original insurer, broker, coverholder, reinsurer, claims administrator or service company. Read the capacity beside the name. An abbreviation copied without capacity can turn a communication route into a contractual duty.
In subscription placements, several reinsurers may accept percentages of one order. “Written line” and “signed line” can differ if the placement is over-subscribed or lines are adjusted. A reader should not multiply the treaty limit by every visible percentage until the basis and final signing are clear.
Check legal names, addresses, regulatory identifiers where supplied, broker reference, unique market reference, stamps, electronic acceptances and date. Reconcile the order total rather than assuming the displayed lines already equal the final participation.
If a slip shows a 120% total written line but a 100% signed order, the economic participation is normally based on the final signed shares. That conclusion still requires the actual signing record and any later line change.
- Create a party-and-capacity table.
- Distinguish written from signed line.
- Verify total order and currency.
- Check authority for each acceptance.
- Preserve the placement reference.
Do not infer solvency, licence status or security quality from the presence of a stamp. Those are separate due-diligence questions.
This is careful noun reading. In school projects and contracts alike, the same person or organisation may perform different roles; the role controls the verb that follows.
Make a two-column placement note for Fix parties, capacities and order. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
A treaty can have a placement date, inception, expiry, signing date, accounting period, premium instalment date, notice deadline and claims reporting date. Put each on a timeline. One date rarely answers when risk attaches, when loss must occur or when payment is due.
The basis of cover may be risks attaching, losses occurring, claims made or another defined trigger. Run-off, portfolio entry, portfolio withdrawal and termination provisions can change what happens at the boundary. A reader who relies only on the heading may include or exclude the wrong underlying business.
Compare the period clause with definitions, termination, special cancellation, sanctions wording and endorsements. Mark time zones if notices or catastrophe hours clauses make them material.
A one-year treaty incepting 1 January may still respond differently to a policy written on 31 December, a loss on 2 January and a claim reported in March depending on the basis. Draw the three dates before deciding.
- Build a complete treaty timeline.
- Label risk, loss and report dates.
- Check run-off and portfolio provisions.
- Mark notice deadlines.
- Verify endorsement effective dates.
Boundary questions can be legally and actuarially complex. Escalate rather than turning a timeline exercise into a coverage opinion.
Timeline literacy transfers to examinations, admissions, project schedules and laboratory work because deadlines describe different events, not a single vague “date”.
Make a two-column placement note for Read dates as a chain, not one field. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
The business-covered clause is the gate into the treaty. Read class, original policy type, cedant branch, insured location, territorial limits, jurisdiction, currency and any portfolio restrictions together. A broad title can be narrowed by a schedule or exclusion.
Terms such as “all business written or renewed” depend on definitions of written, accepted, booked, ceded and the treaty basis. The cedant’s underwriting guidelines or information may be incorporated, represented or supplied for information only. Those statuses are not interchangeable.
Build an inclusion test using actual fields from the wording. Then run borderline examples and cite the clause that admits or rejects each example.
Suppose a regional property policy covers locations in Singapore and a neighbouring country. A Singapore-only territorial clause, a worldwide policy definition and an overseas-location exclusion may pull in different directions. The answer requires the hierarchy and exact drafting.
- Quote the class of business.
- Map territories and jurisdictions.
- Check original policy conditions.
- Test mixed and borderline risks.
- Record incorporated underwriting information.
Do not assume that commercial intention overrides unambiguous text, or that a broad marketing description expands the contract.
The skill is set membership: students learn to decide whether an example satisfies every stated condition and to show which condition fails.
Make a two-column placement note for Define the business covered. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
5. Identify proportional or non-proportional structure
Back to contentsQuota share and surplus treaties share premiums and losses proportionally under defined rules. Excess-of-loss treaties respond above a retention up to a limit, often by risk, event, occurrence or aggregate. Stop-loss structures can respond to portfolio experience. The structure determines the arithmetic and the evidence needed.
A label such as “excess of loss” is incomplete without subject, retention, limit, number of lines or layers, aggregation rule and ultimate net loss definition. For proportional business, the cession percentage, retention, commission and limits on individual risks matter.
Translate the slip into one neutral sentence: who transfers what share or layer of which loss measure, after what retention, up to what limit, over what period. If the sentence cannot be completed, the reading is not finished.
A layer written “10 million excess 5 million” is commonly read as a 10 million limit above a 5 million retention, but currency, basis, aggregation, reinstatement and underlying protection can change the result.
- Name the treaty structure.
- Write retention and limit with currency.
- Identify loss measure and aggregation.
- Map underlying and overlying layers.
- Test one simple numerical scenario.
Illustrative arithmetic is not a claim calculation. Definitions, exclusions, allocation and claims provisions remain controlling.
This combines English with mathematics: accurate words tell the reader which numbers belong in the model and what the result means.
Make a two-column placement note for Identify proportional or non-proportional structure. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
6. Read definitions, exclusions and hours clauses together
Back to contentsDefinitions turn ordinary words into contractual tools. Event, occurrence, loss, risk, disaster, ultimate net loss and original insured can be specially defined. Exclusions then remove categories that might otherwise enter. An hours clause may group losses within a selected period under stated conditions.
Create a cross-reference map instead of copying isolated definitions. A catastrophe exclusion can contain write-backs; a sanctions clause can affect performance; a cyber or communicable-disease exclusion can use its own causation language. Punctuation and connectors such as arising from, caused by or contributed to can matter.
Use one fact pattern and change one variable at a time: cause, location, time, insured interest or policy type. Record which words change the provisional reading.
If storm losses begin on Monday and continue through Thursday, an hours clause may require selection of a continuous window and rules against overlapping. The slip’s exact period and event definition decide the grouping.
- List defined terms used in operative clauses.
- Map exclusion, exception and write-back.
- Mark causation connectors.
- Test hours-clause boundaries.
- Check endorsement changes.
Exclusions and aggregation disputes are specialist matters. Do not promise a coverage outcome from an educational example.
Close reading here resembles literature analysis, but the stakes differ: a connector or definition can redirect money, reporting and dispute.
Make a two-column placement note for Read definitions, exclusions and hours clauses together. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
Treaty economics may include deposit premium, minimum premium, adjustable premium, rate on line, rate on subject premium, ceding commission, profit commission, brokerage, taxes and instalments. Each figure needs a base, period, currency and adjustment rule.
A percentage without its denominator is unfinished information. “10%” might apply to gross net premium income, subject premium, written premium, earned premium, limit or profit. Read definitions and accounting schedules before calculating.
Create an economics table with amount or rate, base, payer, payee, due date, adjustment evidence and dispute route. Reconcile the table to the narrative clauses.
If a minimum and deposit premium is adjusted after year-end, the final premium may depend on declared subject premium subject to a floor. A ceding commission can be calculated on a different base and timing.
- Name every denominator.
- Separate deposit, minimum and final premium.
- Record brokerage and taxes.
- Map instalment and adjustment dates.
- Check currency conversion rule.
This guide does not assess pricing adequacy, accounting treatment or tax. Those require qualified professionals and current requirements.
The learning transfer is dimensional analysis: a rate becomes meaningful only when the reader identifies what it measures and when it applies.
Make a two-column placement note for Connect premium, commission and adjustments. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
8. Understand reinstatements and aggregate exhaustion
Back to contentsA non-proportional treaty can permit the limit to be reinstated after a loss, sometimes automatically, sometimes for additional premium and sometimes only a stated number of times. Aggregate limits and deductibles can cap or delay the treaty’s total response.
Read whether reinstatement is pro rata as to amount, time, both or neither; who gives notice; how additional premium is calculated; and whether the reinstated cover applies from the loss or another point. Then track erosion across losses.
Use a layer ledger: opening limit, each qualifying loss, retention allocation, paid or reserved erosion, reinstated amount, premium consequence and remaining aggregate.
A first loss that uses half a layer may leave half available and trigger a partial reinstatement. A second loss can interact with the restored limit and aggregate cap. The wording—not a generic diagram—controls the ledger.
- Locate number of reinstatements.
- Identify premium basis.
- Track erosion and restoration.
- Check aggregate cap or deductible.
- Reconcile paid and reserved views.
Loss allocation and reinstatement calculations can be contested. Keep assumptions visible and obtain actuarial, claims and legal review where required.
This is cumulative reasoning: students see why a later result depends on the state left by earlier events.
Make a two-column placement note for Understand reinstatements and aggregate exhaustion. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
9. Read accounts and bordereaux as treaty operations
Back to contentsBordereaux and statements of account turn the treaty into recurring information flows. They may report premiums, risks, losses, reserves, cash calls, recoveries and adjustments on monthly, quarterly or other cycles.
The clause should identify format, data fields, valuation date, currency, due date and correction process. Data quality affects administration and can affect decisions, but a late or inaccurate bordereau does not have one universal consequence; the contract must be read.
Trace one number from the cedant’s source system through the bordereau, broker account and reinsurer record. Preserve version, extraction date and reconciliation notes.
A large-loss bordereau may show an incurred amount that combines paid loss and outstanding reserve. If the treaty responds to paid loss for cash-call purposes, the same figure cannot be reused without adjustment.
- List required reports and frequency.
- Define paid, outstanding and incurred.
- Check data and currency fields.
- Reconcile revisions.
- Map consequences of error or delay.
Treat personal and confidential information according to law, contract and security policy. More data is not automatically better data.
This is spreadsheet literacy with language controls: column labels, definitions and reporting dates determine what a total actually represents.
Make a two-column placement note for Read accounts and bordereaux as treaty operations. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
10. Separate notice, cooperation, control and settlement
Back to contentsClaims clauses may require notice of losses or circumstances, information, consultation, cooperation, consent, claims control, follow-the-settlements or follow-the-fortunes wording. These concepts should not be collapsed into “tell the reinsurer”.
Read who must notify whom, what threshold triggers notice, the deadline, content, continuing updates and consequence of breach. Then distinguish the cedant’s authority over the underlying claim from any reinsurer participation rights.
Build a claims communication map and attach every message to the relevant clause, claim identifier and date. A courteous email is not necessarily contractual notice; an acknowledgement is not necessarily consent.
If a cedant settles an underlying claim after consulting reinsurers, recovery can still depend on treaty wording, good faith, coverage, allocation and any consent requirement. Avoid slogans.
- Identify notice trigger and deadline.
- Distinguish cooperation from control.
- Record consent points.
- Preserve settlement rationale.
- Check allocation across years and treaties.
Real claims require professional review. This article does not advise whether a settlement is recoverable.
English makes authority visible. The verbs inform, consult, approve, direct and settle allocate different powers and should remain distinct.
Make a two-column placement note for Separate notice, cooperation, control and settlement. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
11. Control endorsements and the contract hierarchy
Back to contentsA slip evolves through endorsements, signing-down records, line changes, premium adjustments and correspondence. Treat every change as a controlled amendment with an effective date and a target clause.
Read the precedence or entire-agreement provisions and identify which schedules, attachments and prior communications are incorporated. Do not silently merge drafts. A later endorsement may replace one phrase and leave the rest untouched.
Maintain a clause register showing original wording, amendment, effective date, acceptance evidence and downstream effects on accounts or claims.
An endorsement changing territorial scope from inception can affect risks already booked, whereas a prospective change may not. The endorsement’s wording and effective date need to be read together.
- Freeze the operative version.
- Apply endorsements only to named provisions.
- Check retrospective or prospective effect.
- Reconcile line changes.
- Archive superseded drafts without using them.
Document hierarchy and amendment disputes are legal questions. The register supports review; it does not decide enforceability.
Version control is an English skill and a digital-life skill: readers need to know which words were current when the decision was made.
Make a two-column placement note for Control endorsements and the contract hierarchy. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
12. Read law, arbitration, sanctions and expert limits
Back to contentsGoverning law, jurisdiction or arbitration, seat, rules, appointment method, confidentiality, service and language clauses shape how disagreements are handled. Sanctions, insolvency and termination provisions can affect performance and security.
Do not confuse governing law with arbitration seat, hearing location or court jurisdiction. Check inconsistent clauses across the slip and attached wording. A sanctions provision should be read with current applicable law and the parties’ actual status, not from a static checklist.
Create a dispute-route card with notice step, negotiation period, forum, seat, rules, number of arbitrators, service addresses and limitation concerns for professional review.
A clause choosing Singapore law and London arbitration can be possible; each phrase answers a different question. The operational team should not ‘correct’ the apparent mismatch without advice.
- Separate law, seat and venue.
- Verify arbitration rules and version.
- Check service and notice.
- Escalate sanctions screening.
- Preserve evidence and privilege.
Reinsurance is regulated, cross-border and legally complex. Use brokers, underwriters, actuaries, claims professionals and lawyers. Clear reading supports them; it does not replace them.
This final chapter teaches intellectual humility: precise English shows both what the document says and where specialised judgment begins.
Make a two-column placement note for Read law, arbitration, sanctions and expert limits. In the left column copy the controlling words, defined term, number, attachment reference or endorsement. In the right column write the commercial question those words answer. Then compare the result with the contract schedule, definitions, exclusions and any later endorsement. This prevents a memorable phrase in the slip from outranking the document hierarchy. If the answer still depends on underwriting intent, market practice or governing law, mark it for a broker, underwriter or lawyer instead of inventing certainty.
Read a fictional catastrophe excess-of-loss slip from first page to final endorsement
Back to contentsA fictional cedant offers a property catastrophe treaty described as SGD 20 million excess SGD 5 million, two paid reinstatements, 1 January to 31 December. The order is 100%, written lines total 125%, and an endorsement changes one territorial phrase. A storm affects several insured locations over four days.
Build the orientation card
Record parties and capacities, broker reference, version, signed lines, currency, period and incorporated wording. Do not calculate participation from written lines until the signing record is fixed.
Write the risk-transfer sentence
Complete: the reinsurers accept their signed shares of qualifying ultimate net loss from the defined property portfolio, above the cedant’s retention and up to the layer limit, subject to the event definition, hours clause, exclusions, aggregate provisions and reinstatements. Mark every word that still needs a clause reference.
Run the storm timeline
- List each location and original policy
- Plot damage times and causes
- Apply the event definition and permissible hours window
- Check retention and layer once the grouping is supportable
- Track limit erosion and reinstatement
- Record alternative groupings for specialist review
Reconcile economics and claims communication
Calculate nothing from a floating percentage. Identify the premium base, instalments, brokerage and reinstatement-premium rule. Then map notice, cooperation, consent and settlement steps for the fictional claim.
No one may call the treaty ‘confirmed’ until the operative version, final signed lines, incorporated wording and endorsement are reconciled.
A second reader should be able to reproduce the provisional map and see every assumption, clause reference and unresolved professional question.
Is a treaty slip the whole contract?
Sometimes the slip is central, but the operative contract may also include wordings, schedules, endorsements, signing records and incorporated material. Read the hierarchy and execution evidence.
What is the difference between quota share and excess of loss?
Quota share generally shares an agreed proportion of premiums and losses; excess of loss generally responds above a retention up to a limit. Exact wording controls.
Does ‘10 million excess 5 million’ guarantee 10 million of recovery?
No. It describes a layer in shorthand. Coverage, aggregation, exclusions, allocation, reinstatements, aggregate limits, signed shares and claims provisions still matter.
What is an hours clause?
It can define or constrain how catastrophe losses occurring within a selected continuous period are grouped. The period, cause and selection rules must be read exactly.
Why do written and signed lines differ?
In a subscription placement, offered lines can exceed the order. Signing down can convert written lines into final participations. Use the actual signing record.
Is this legal or underwriting advice?
No. It is a reading framework. Real placements and claims require the complete file and authorised professional judgment.

The best treaty reader does not race toward a payout figure. They build a controlled map of parties, portfolio, trigger, layer, economics, claims duties and amendments—then invite the right specialists to test it.
