Understanding Proximate Cause
In the world of insurance adjusting, particularly within the scope of the complete CAT Adjuster exam guide, the Doctrine of Proximate Cause stands as a fundamental pillar. It is the legal and contractual principle used to determine whether a loss was caused by a peril covered under the policy.
Proximate cause is defined as the active, efficient cause that sets in motion a train of events which brings about a result, without the intervention of any force started and working actively from a new and independent source. For a catastrophe adjuster, identifying the proximate cause is not always straightforward, especially when multiple perils—such as wind, hail, and rising water—occur simultaneously or in quick succession.
The 'But For' Test
A common method for determining proximate cause is the 'But For' test. The adjuster asks: 'But for the occurrence of Peril A, would the loss have occurred?' If the answer is no, Peril A is often considered the proximate cause. However, this is further complicated by the presence of concurrent causation and policy exclusions.
Efficient Proximate Cause (EPC) vs. Concurrent Causation
When two or more perils contribute to a loss, adjusters must distinguish between Efficient Proximate Cause and Concurrent Causation. These concepts are frequently tested on the practice CAT Adjuster questions because they dictate whether a claim is paid or denied.
- Efficient Proximate Cause: This refers to the dominant cause that set the loss in motion. If the dominant cause is a covered peril, the entire loss is typically covered, even if an excluded peril contributed to the damage later in the chain.
- Concurrent Causation: This occurs when two perils happen at the same time to cause a single loss. If one peril is covered and the other is excluded, the outcome depends on state law and specific policy language.
EPC vs. Anti-Concurrent Causation (ACC)
| Feature | Efficient Proximate Cause (EPC) | Anti-Concurrent Causation (ACC) |
|---|---|---|
| Focus | The dominant 'trigger' event | Exclusionary language regardless of order |
| Coverage Result | Covers loss if the primary cause is covered | Denies loss if an excluded peril is involved at all |
| Common Peril | Fire leading to water damage | Flood occurring with Hurricane winds |
The Role of Anti-Concurrent Causation Clauses
Modern insurance policies, especially Homeowners (HO-3) forms, often include an Anti-Concurrent Causation (ACC) clause. This clause is a direct response to legal rulings that favored policyholders under the EPC doctrine. An ACC clause explicitly states that if an excluded peril (such as an earthquake or flood) contributes to a loss, the loss is excluded regardless of any other cause or event contributing concurrently or in any sequence to the loss.
For a catastrophe adjuster, this is vital. If a hurricane brings both high winds (covered) and a storm surge (excluded flood), and the policy contains an ACC clause for flood, the adjuster must carefully segregate the damage. Damage caused solely by wind may be covered, but any damage where the flood contributed may be excluded entirely under the ACC provision.
Key Adjuster Considerations
Practical Application in Catastrophes
In a catastrophe scenario, the sequence of events is paramount. Consider a tornado that lifts a roof, followed by a torrential downpour. The proximate cause is the wind (tornado). Because wind is a covered peril, the subsequent water damage to the interior is also covered, as it is part of an unbroken chain of events initiated by the wind.
Conversely, if a pipe bursts (covered) and causes a small amount of water damage, but then a massive flood (excluded) inundates the home, the adjuster must determine which damage was caused by which peril. Without an ACC clause, the 'burst pipe' might be seen as the proximate cause for certain areas, but with an ACC clause, the flood's involvement might preclude coverage for overlapping damage.
