Answer: Higgins should report this litigation as a contingent liability.
Explanation: A liability that is contingent upon an event, that is, dependent on a future event that may or may not happen is called contingent liability. Potential law suits, pending investigations are some of the examples of contingent liability.
A contingent liability will only be recorded if there is likely probability that the event on which such liability depends will occur and the amount of liability could be reasonably estimated.
