Final answer:
The correct statement is (c). Under the completed-contract method, when billings exceed accumulated costs, the estimated loss is reported as a current liability, and not recognized until the contract is completed.
Step-by-step explanation:
When cost estimates at the end of the second year indicate a loss on the completion of a contract, there are different implications depending on the accounting method used. With the completed-contract method, a loss is not recognized until the project is completed, therefore statements (a) and (c) could be plausible. However, under the percentage-of-completion method, if a loss is anticipated, it must be fully recognized immediately, disagreeing with statement (b). For the completed-contract method, when billings exceed accumulated costs, the loss is recognized as a current liability, making statement (c) correct. This means that the amount of the estimated loss is reported as a current liability rather than being added to the accumulated costs, as suggested in statement (d).
