This report provides an analysis of Australian Accounting Standards Board (AASB) 116 in the context of plant, property, and equipment (PPE) depreciation, particularly focusing on the case of Sea Eagle Ltd. The report addresses the policies and procedures related to the leasing of assets and liabilities, especially those exceeding 12 months, as governed by AASB 16. It examines whether depreciation should be charged during periods when assets are idle, referencing AASB 116 guidelines. The analysis considers the impact of a strike at Sea Eagle Ltd on its plant operations, requiring an evaluation of PPE depreciation under AASB 16. The report, presented from the perspective of an auditing team member, provides insights into the factors influencing depreciation, including asset usage, wear and tear, and obsolescence, ultimately concluding that depreciation should be charged even during idle periods, irrespective of physical asset use. The report also touches on how events like strikes can influence the estimated life and residual value of assets, affecting depreciation calculations.
