Answer:
The answer is: Probable and the amount of the loss can be reasonably estimated.
Explanation:
Losses should be recorded as soon as possible (conservatism principle) as long as they are probable and can be reasonably estimated. A loss doesn't have to occur to be recorded, that is why they are recorded as contingency losses. If the company finds it probable that a loss will happen but can't estimate it, then it can't record it as a contingency loss.
