Answer:
an accrual.
Step-by-step explanation:
Accruals are a type of liability. They are expenses that have been incurred by the company, but have not been paid yet.
The accident resulted in a loss contingency and since it was probable and could be reasonably estimated, it must be included in the balance sheet. Balance sheets must be adjusted when certain relevant events are known after the year ended, but before the balance sheet is presented.
