Definition:Particular average (PA)
⚓ Particular average (PA) is a marine insurance term for a partial loss that affects only a specific interest — a single cargo owner's goods or the shipowner's vessel — rather than being shared among all parties to the maritime venture. It stands in contrast to general average, where a sacrifice or expenditure is deliberately made for the common safety of the voyage and the resulting loss is apportioned among all stakeholders. A PA loss might arise from storm damage to a particular consignment of goods, seawater ingress into one hold, or localised hull damage from striking a submerged object — situations where the financial burden falls on the party whose property was damaged and, by extension, on that party's insurer.
📐 Under the Institute Cargo Clauses widely used in London and many international markets, coverage for particular average depends on which set of clauses has been selected. Institute Cargo Clauses (A) — the broadest form — cover PA losses on an "all risks" basis, subject to stated exclusions. Institute Cargo Clauses (B) and (C) cover PA only when caused by specifically listed perils such as fire, vessel stranding, or collision, and many historic policies contained a "free of particular average" (FPA) warranty that excluded PA claims entirely unless the vessel had been involved in a major casualty. On the hull side, hull and machinery policies typically cover PA losses for physical damage to the ship itself, with the shipowner bearing a deductible — often significant — before the insurer's liability attaches. Adjusters and marine surveyors assess the extent of damage and determine whether costs qualify as PA or fall under another category, such as salvage or general average contribution.
🔍 Understanding the distinction between particular average and general average is essential for anyone involved in marine underwriting, claims handling, or cargo trade finance. A buyer of cargo insurance who selects a narrower set of clauses to save on premium may find that routine transit damage — crushed packaging, moisture damage, temperature fluctuation — falls outside cover because it constitutes a PA loss from an unlisted peril. Conversely, underwriters pricing marine cargo books must model the frequency and severity of PA claims, which far outnumber general average events. The concept also carries practical importance in jurisdictions from Scandinavia to East Asia, where local marine insurance codes and plan wordings define particular average with slight terminological variations but the same underlying principle: partial losses borne by the individual interest rather than shared across the voyage community.
