Which losses occur due to predictable factors rather than unforeseen events?

Nonaccidental losses are defined by factors that can be anticipated, planned for, or are the result of circumstances that are not random in nature. They typically arise from predictable events, like wear and tear or maintenance issues, instead of unforeseen circumstances such as natural disasters or accidents. By focusing on losses that can be expected based on prior trends or behaviors, this category is distinct from others that often involve unexpected occurrences.

In contrast, direct losses usually refer to damages directly caused by an event, while indirect losses stem from the economic consequences that follow a direct loss. Extra-hazardous perils denote risks that materially increase the likelihood of loss, but they are associated more with unpredictability than with the predictability inherent to nonaccidental losses. Recognizing the characteristics of nonaccidental losses helps differentiate between types of losses that insurance professionals need to understand for proper coverage and risk assessment.
