(a) A director of Enca, a public listed company, has expressed concerns about the accounting treatment of some of the company’s items of property, plant and equipment which have increased in value. His main concern is that the statement of financial position does not show the true value of assets which have increased in value and that this ‘undervaluation’ is compounded by having to charge depreciation on these assets, which also reduces reported profit. He argues that this does not make economic sense. Required: Respond to the director’s concerns by summarising the principal requirements of IAS 16 Property, Plant and Equipment in relation to the revaluation of property, plant and equipment, including its subsequent treatment. (b) The following details relate to two items of property, plant and equipment (A and B) owned by Delta which are depreciated on a straight-line basis with no estimated residual value: At 31 March 2014 item A was still in use, but item B was sold (on that date) for $70 million. Note: Delta makes an annual transfer from its revaluation surplus to retained earnings in respect of excess depreciation. Required: Prepare extracts from: (i) Delta’s statements of profit or loss for the years ended 31 March 2013 and 2014 in respect of charges (expenses) related to property, plant and equipment; (ii) Delta’s statements of financial position as at 31 March 2013 and 2014 for the carrying amount of property, plant and equipment and the revaluation surplus. The following mark allocation is provided as guidance for this requirement: (i) 5 marks (ii) 5 marks (10 marks)
