The Answer in 60 Seconds

Property All Risks (PAR) policies operate on an "all risks" basis — covering any sudden and accidental physical loss / damage except specifically excluded. The exclusions are therefore foundational: they define where coverage ends. Standard PAR exclusions include: wear and tear / gradual deterioration, inherent vice / latent defect, mechanical / electrical breakdown (often, with separate Equipment Breakdown cover available), faulty design / workmanship (varies), specific consequential losses, war / nuclear / radioactive, specific cyber-related exclusions (evolving), and specific other defined exclusions. For Singapore SMEs evaluating PAR cover (per Article 158), understanding the exclusions explains both what's actually covered and where complementary covers (Equipment Breakdown, Cyber, specific specialty covers) become essential. The 2017-2024 period has seen significant evolution in cyber-related exclusions across the global property market — Singapore-issued PAR policies have followed these trends.

The Sourced Detail

PAR's broad coverage scope is defined negatively — through what's excluded rather than what's listed. Understanding the exclusions in detail is therefore foundational for SMEs procuring PAR cover, both for understanding actual coverage and for identifying complementary cover needs. PAR operates within the Insurance Act 1966 framework administered by MAS, with industry conventions documented by the General Insurance Association of Singapore (GIA). Specific exclusion case law and dispute resolution treatment is available through eLitigation.

Wear and tear / gradual deterioration

The exclusion. Loss / damage from wear and tear, gradual deterioration, ordinary use is excluded.

The rationale. Insurance is designed for sudden and accidental events. Predictable deterioration is operational cost, not insurable risk.

Common application scenarios:

  • Roof gradually deteriorating and beginning to leak — excluded
  • Specific equipment showing age-related decline — excluded
  • Specific materials reaching end of useful life — excluded
  • Specific floor wear from regular use — excluded

The boundary issue. The line between "gradual deterioration" and "sudden and accidental" can be disputed:

  • Gradual deterioration that culminates in sudden failure (e.g. accumulating roof damage that finally fails during storm) — typically the sudden failure portion is covered, the gradual portion is not
  • Specific maintenance-related issues — typically excluded if attributable to inadequate maintenance
  • Specific industrial wear patterns — typically excluded

Operational implications. Maintenance discipline matters substantially:

  • Regular inspection regimes
  • Specific maintenance documentation
  • Considerations on equipment lifecycle

Without maintenance discipline, claims may face wear-and-tear exclusion challenges.

Inherent vice / latent defect

The exclusion. Loss / damage attributable to inherent vice (qualities of the insured property that cause it to deteriorate) or latent defect (defects existing at insurance inception not discoverable through reasonable inspection) is excluded.

The rationale. Property's intrinsic characteristics that cause deterioration are not insured perils.

Common application scenarios:

  • Specific commodity inherent characteristics (e.g. specific food spoilage, specific chemical instability) — excluded
  • Specific manufacturing defects existing at inception — excluded if latent
  • Specific structural issues from original construction — excluded if latent
  • Specific equipment design characteristics — excluded

The boundary with manufacturing defect. Specific manufacturing defects can cross between latent (excluded) and patent (covered if accidentally manifesting):

  • Latent defect existing at inception, manifesting as gradual deterioration — excluded
  • Patent defect causing sudden accidental damage — typically covered (subject to specific manufacturing defect exclusions where applicable)

Operational implications.

For specific industries (manufacturing, food, specific equipment-heavy):

  • Quality assurance documentation
  • Specific supplier qualification
  • Specific incoming inspection
  • Operational considerations

Mechanical / electrical breakdown

The exclusion. Mechanical or electrical breakdown of equipment is typically excluded from standard PAR. The rationale: breakdown is generally a function of equipment lifecycle and operation, not external sudden events.

Specific scope. "Mechanical / electrical breakdown" typically includes:

  • Equipment malfunction from internal causes
  • Specific electrical short circuit damage
  • Specific motor / pump / compressor failure
  • Specific control system failure

The Equipment Breakdown (EBD) cover alternative.

Equipment Breakdown (also called Boiler & Machinery in some markets) provides specific cover for breakdown scenarios:

  • Internal breakdown causes
  • Specific resulting damage to equipment
  • Specific consequential damage to other property
  • Specific BI extension
  • Specific extra expense extension

EBD is a specialty cover separate from PAR. For SMEs with material equipment dependencies (manufacturing, hospitality with substantial kitchen equipment, specific industries), EBD is operationally essential complement to PAR.

The boundary with sudden accidental damage.

Specific scenarios cross the boundary:

  • External force causing equipment damage — typically PAR
  • Internal breakdown — typically EBD
  • Specific lightning strike causing electrical damage — depends on policy and circumstances
  • Specific power surge — depends

Faulty design / workmanship

The exclusion. Loss / damage attributable to faulty design, faulty workmanship, or faulty materials is typically excluded — at least in part.

Specific variations. Different policy forms handle this differently:

  • "Defective" property exclusions excluding cost of correcting the defect itself
  • Specific exclusions excluding consequential damage caused by the defect
  • Specific carve-outs for resulting accidental damage

Specific common scenarios:

  • Building constructed with defective materials, materials fail and damage other property:
    • Cost of replacing defective materials: typically excluded
    • Damage to other property: often covered
  • Equipment installation defective, equipment fails causing damage:
    • Cost of correcting installation: typically excluded
    • Resulting damage: often covered

Specific industry applications. Construction industry has specific frameworks; commercial relationships and contractual provisions matter.

Consequential losses

The exclusion. PAR typically excludes consequential losses — losses arising from but not directly being physical damage to insured property.

Specific scope. Consequential losses include:

  • Business interruption (handled by separate BI cover; see Article 159)
  • Specific loss of contracts
  • Specific loss of market / reputation
  • Specific loss of profit beyond BI cover
  • Specific other commercial impacts

Specific BI integration. BI typically procured alongside PAR addresses the most material consequential loss category.

Specific extra expense extension. Some PAR policies include specific extra expense provisions covering costs incurred to maintain operations during disruption.

War / nuclear / radioactive

The exclusion. Standard exclusions for war (and related perils), nuclear / radioactive incidents.

Specific scope. War exclusions typically extend to:

  • Declared war
  • Specific civil war / insurrection
  • Specific terrorism (with specific carve-outs in some markets)
  • Specific other war-adjacent

Nuclear / radioactive exclusions typically broad.

Specific terrorism considerations.

Singapore market addresses terrorism through:

  • Standard exclusions in basic policies
  • Specific terrorism extensions / standalone covers
  • Operational considerations

For specific premises types (high-profile commercial, specific high-density urban, specific industries), terrorism extension may be appropriate.

Cyber-related exclusions

The evolving area. Cyber-related exclusions have evolved substantially in the property market 2017-2024:

The pre-NMA 2914 era. Most PAR policies were silent on cyber. Specific scenarios (cyber attack causing physical damage, malware bricking equipment) generated uncertain claims responses.

The NMA 2914 / NMA 2915 era. Lloyd's market introduced specific cyber exclusions — addressing cyber attack as cause but with specific carve-outs for physical damage to insured property.

The LMA5400 / LMA5401 evolution. Subsequent evolution — the Lloyd's Market Association property cyber endorsement (LMA5400) and exclusion (LMA5401), published November 2019 — clarified scope further:

  • Specific physical damage from cyber attack — often carved back in
  • Specific cyber-only loss — excluded
  • Specific industry-specific provisions

The current Singapore market. Most Singapore PAR policies now include specific cyber exclusions with specific carve-out provisions. Standalone Cyber Liability (see Article 167) addresses the cyber-specific scope.

The integration question. For SMEs, the question is whether physical damage from cyber attack is covered:

  • Standard PAR typically excludes the cyber attack cause
  • Specific carve-outs may cover physical damage even from cyber
  • Standalone Cyber may address the operational disruption / data dimensions
  • Operational considerations required

Specific exclusions for specific commodities / equipment

Specific commodity exclusions.

Some PAR policies have specific commodity exclusions:

  • Specific high-value commodities (jewelry, watches) typically have sub-limits or specific exclusions
  • Specific perishable commodities specific provisions
  • Specific high-risk commodities specific exclusions

Specific All Risks Stock cover.

For specific high-value or substantial inventory, specific All Risks Stock cover (see Article 154) addresses commodities that PAR may underinsure.

Specific underinsurance / average

The average clause.

Most PAR policies include an "average" or "underinsurance" clause:

  • If sum insured is less than actual value, claim is reduced proportionately
  • Operational considerations required
  • Annual valuation review essential

Operational discipline.

For PAR procurement:

  • Annual asset valuation review
  • Specific replacement cost basis
  • Operational considerations
  • Specific commercial customer / lender requirements

Specific contractual exclusions / carve-backs

PAR policies often have specific provisions:

Negotiated carve-backs.

For operational scope, specific exclusions may have negotiated carve-backs:

  • Specific manufacturing defect carve-backs
  • Specific cyber-related carve-backs
  • Operational considerations

Specific industry-specific provisions.

Specific industries have specific PAR conventions:

  • Construction (specific Contract Works, specific defects liability provisions)
  • Manufacturing (specific machinery / equipment provisions)
  • Hospitality (specific premises and contents provisions)
  • Commercial conventions

Operational considerations

For SMEs evaluating PAR cover:

Comprehensive exclusion review. Each major exclusion should be understood for operational implications.

Specific complementary cover assessment. Equipment Breakdown, Cyber, specialty covers identified.

Operational discipline. Maintenance, quality assurance, commercial discipline supports defence to exclusion-based claim disputes.

Operational considerations. Specific industry-aware broker engagement.

Annual review. Specific evolving market conventions, operational scope.

Common Mistakes / What Goes Wrong

  1. Wear and tear exclusion underestimated. Specific maintenance-related claim challenges.
  2. No Equipment Breakdown for material equipment. Specific exclusion gap.
  3. Cyber-related exclusion not understood. Specific physical damage from cyber attack uncertainty.
  4. No All Risks Stock for high-value inventory. Specific underinsurance.
  5. Specific consequential losses gap. Specific BI gap exposure.
  6. No terrorism extension where appropriate.
  7. Specific average clause underestimated. Specific underinsurance discount.
  8. No commercial customer / lender certificate compliance. Specific commercial breach.
  9. No exclusion negotiation where commercially appropriate.
  10. No annual review. Specific evolving market and operational scope.

What This Means for Your Business

For Singapore SMEs:

  1. PAR's exclusions matter as much as its coverage scope. operational understanding.

  2. Identify complementary cover needs. Equipment Breakdown, Cyber, specialty covers.

  3. Maintain operational discipline supporting defence to exclusion-based disputes. Specific maintenance, QA documentation.

  4. For operational considerations, specialist broker. Specific exclusion negotiation.

  5. Annual valuation review. Specific average clause discipline.

  6. For specific industry / commercial scope, specific provisions.

  7. Coordinate PAR with BI and other related covers. Specific integrated programme.

  8. Annual review covering operational evolution.

The PAR exclusion architecture is foundational for understanding what's actually covered. SMEs that engage thoughtfully with the exclusions and procure complementary covers benefit from comprehensive protection; SMEs that treat PAR as monolithic "all risks" cover face gap exposure at claim time.
