Workers Compensation Â鶹Éç
Workers compensation insurance provides for the cost of medical care and rehabilitation for injured workers and lost wages and death benefits for the dependents of persons killed in work-related accidents. Workers compensation systems vary from state to state. Workers compensation combined ratios are expressed in two ways. Calendar year results reflect claim payments and changes in reserves for accidents that happened in that year or earlier. Accident year results only include losses from a particular year.
