Final answer:
In the situation where Hanna Company is being sued, the contingency should be treated as a contingent liability and disclosed in the financial statements. Alijah Oil Refinery should also disclose their situation as a contingent liability since they believe they will have to pay for clean-up costs and damages due to the gas explosion. Lambert Enterprises' estimation of warranty repairs is not a contingent liability, but a known and probable liability.
Step-by-step explanation:
Part a: In the case of Hanna Company being sued by a former employee, since Hanna Company believes that there is a remote chance that the employee will win, the situation should be disclosed in the notes to the financial statements as a contingent liability. Contingent liabilities are potential liabilities that may arise in the future depending on the outcome of uncertain events. In this case, the potential liability is $20,000 in damages if the employee wins the lawsuit.
Part b: For Alijah Oil Refinery, since they believe it is likely that they will have to pay environmental clean-up costs and damages due to the gas explosion, but cannot estimate the amount, the situation should be disclosed in the notes to the financial statements as a contingent liability. In this case, the contingency is the obligation to pay for clean-up costs and damages, and the amount is uncertain.
Part c: In the case of Lambert Enterprises estimating that they will have to pay $20,000 in warranty repairs next year, this is not a contingent liability. It is a known and probable liability because Lambert Enterprises has a legal or constructive obligation resulting from a past event, and it is probable that an outflow of resources will be required to settle the obligation.
