The Answer in 60 Seconds
Insurance limit structure framework distinguishes per-occurrence limits (cap per individual incident) and aggregate limits (cap across policy period). Public Liability cover conventionally provides both per-occurrence limit and aggregate limit. Professional Indemnity and Cyber Liability cover typically operate on aggregate-only basis. Commercial implications include limit erosion scenarios where multiple claims during policy period may exhaust aggregate limit, considerations on limit reinstatement provisions where applicable, specific defence cost allocation scope (within or outside limits), and framework for limit selection given commercial scope. Singapore commercial cover operates within Insurance Act 1966 framework administered by MAS, with industry conventions documented by General Insurance Association of Singapore (GIA).
The Sourced Detail
Insurance limit structure framework operates as commercial scope mechanism.
The per-occurrence limit framework
Per-occurrence limit caps insurer liability per individual incident / occurrence. Operational scope considerations:
Per-occurrence resilience: per-occurrence limits provide resilience for substantive single incidents.
The aggregate limit framework
Aggregate limit caps insurer liability across policy period. Operational scope considerations:
The combined limit structure framework
Combined per-occurrence + aggregate — Public Liability conventionally provides per-occurrence limit (cap per incident) plus aggregate limit (cap across policy period). Aggregate limit typically substantial multiple of per-occurrence limit.
Aggregate-only structure — Professional Indemnity, Cyber Liability conventionally provide aggregate limit only. Framework for continuing exposure across policy period.
Per-claim + aggregate — considerations on per-claim limit plus aggregate framework.
The defence cost allocation framework
Defence costs within limits — defence costs erode aggregate limit. Framework for scenarios where substantial defence costs may exhaust aggregate limit.
Defence costs outside limits — defence costs do not erode aggregate limit; insurer pays defence costs in addition to indemnity limit. Framework for premium implications.
Hybrid frameworks — considerations on hybrid frameworks combining elements.
The limit reinstatement framework
Automatic reinstatement — considerations on automatic reinstatement provisions. Limit reinstates automatically after exhaustion subject to operational provisions.
The commercial scenario analysis
Commercial scenarios under limit structure framework:
Single substantive incident — considerations on per-occurrence limit adequacy.
Multiple smaller claims — considerations on aggregate limit erosion.
Substantive defence cost scenario — considerations on defence cost allocation scope.
Late-policy-period claim scenario — considerations on scenarios where late-policy-period claim faces eroded aggregate.
The commercial sophistication framework
Specific broker engagement — commercial relationships supporting limit structure analysis.
Commercial counsel engagement — commercial relationships for operational scope.
Common Mistakes / What Goes Wrong
- Inadequate per-occurrence vs aggregate distinction.
- No aggregate erosion scenarios.
- Inadequate defence cost allocation.
- No limit reinstatement provisions where applicable.
- Inadequate occurrence definition framework.
- No batch / event aggregation provisions.
- Inadequate limit appropriateness assessment.
- No broker engagement for limit structure analysis.
- No commercial counsel engagement for operational scope.
- No annual review covering limit structure adequacy.
What This Means for Your Business
For Singapore SMEs:
Limit structure framework substantively shapes commercial scope. Public Liability conventionally provides combined per-occurrence + aggregate structure. Professional Indemnity and Cyber Liability conventionally operate aggregate-only. Considerations on defence cost allocation, limit reinstatement provisions, occurrence definition framework, and limit appropriateness assessment matters substantially.
For substantive operations, specific broker engagement and commercial counsel engagement form the foundation.
