Answer:
$300,000 amount should be accrued as a liability
Step-by-step explanation:
This is an example of a contingent liability.
A contingent liability can be described as a liability which its likely occurrence depends on the outcome of an uncertain future event.
In the accounts, the contingent liability will therefore be recorded if the contingency is probable and it is reasonably possible to estimate the amount of the liability.
In the quesion, it is stated the contingency is probable and that they estimate that the amount of the loss will be $300,000. Therefore, the proper accounting treatment for the contingency is "$300,000 amount should be accrued as a liability".
