Applying accounting theory    LO1, 4, 5, 6 In June 2018 Great Southern Ltd built a submarine under a contract with the Australian Navy. The contract required Great Southern Ltd to provide a 1‐year warranty. The accountant was unsure how to measure the warranty because the design of the submarine differed from those previously built by Great Southern Ltd. The trainee accountant was asked to obtain more information, so she asked some engineers for their advice on the expected cost of servicing the warranty. The trainee’s report is summarised below. Engineers’ estimates and accompanying explanations Worst‐case scenario $3 000 000 Best‐case scenario $ 600 000 Most probable scenario $1 500 000 Quote from a Japanese company to take on the warranty $2 000 000 Recommendation: The provision for warranty should not be recognised because it is too difficult to measure. The accountant needs to decide whether to recognise a provision for warranty and, if so, how to measure it. Required 1. Describe two principles from AASB 137/IAS 37 that are relevant to the accountant’s decision. 2. Use the principles identified in requirement 1, above, to evaluate the trainee accountant’s recommendation. 3. Describe an accounting policy to account for the provision for warranty. 4. Explain how the policy that you proposed in requirement 3 is consistent with AASB 137/IAS 37. 5. Identify assumptions made in the exercise of judgement in proposing an accounting policy for the warranty.
