Step-by-step explanation:
The condition for accruing a liability for the cost of compensation for future absences is all of these options mentioned in the question: a) The obligation relates to the rights that vest or accumulate, b) Payment of the compensation is probable, and c) The obligation is attributable to employee services already performed.
Workman's compensation insurance is a type of liability that employers accrue to cover the cost of compensating employees for future absences due to work-related injuries. When an employee gets injured on the job, the compensation is paid from the funds funded by employers.
For example, if an employee breaks their leg while working, the employer may have a liability to compensate them for the medical expenses, lost wages, and other costs associated with the injury. This liability is accrued when the obligation meets the conditions mentioned above.
