Definition:Adjusting and other expense (A&O)
đ° Adjusting and other expense (A&O) is a component of loss adjustment expense that captures the internal costs an insurer incurs to investigate, manage, and settle claims. These costsâsalaries of staff adjusters, rent for claims offices, internal claims-management system expenses, and related overheadâare sometimes referred to as unallocated loss adjustment expenses (ULAE) because they cannot be traced to a single claim the way a legal bill or an independent adjuster's invoice can.
đ Carriers track A&O expenses as part of their broader expense management and reserving processes. Actuaries estimate future A&O liabilities using methods such as the paid-to-paid ratio approach, which relates cumulative A&O spending to cumulative paid losses. Because A&O costs are influenced by staffing decisions, technology investments, and operational efficiency, they can shift significantly when an insurer restructures its claims department or outsources work to a third-party administrator. These estimates feed into the loss reserves reported on the insurer's annual statement and are scrutinized during statutory examinations.
đ A&O expenses directly affect an insurer's combined ratio and, by extension, its competitive positioning. Insurers that invest in automationâ straight-through processing for simple claims, AI-assisted triage, digital FNOL intakeâcan drive down A&O costs per claim while maintaining or improving service quality. For insurtechs pitching claims technology, demonstrating measurable A&O savings is often the most persuasive argument in a carrier's procurement conversation.
