a a) Delat(DT) ltd acquired an item of plant at a cost of GHS800,000 on 1 April 2010. The plant had an estimated residual value of GHS50,000 and an estimated life of five years, neither of which has changed. DT ltd uses straight-line depreciation. On 31 March 2012, DT ltd was informed by a major customer (who buys products produced by the plant) that it would no longer be placing orders with DT Ltd. Even before this information was known, DT Lid had been having difficulty finding work for this plant. It now estimates that net cash inflows earned from the plant for the next three years will be: GHS'000 Year ended: 31 March 2013 220 31 March 2014 180 31 March 2015 170 DT Lid has confirmed that there is no market in which to sell the plant at 31 March 2012, but is confident that it can still be sold for its original estimated realisable value on 31 March 2015. DT Ltd's cost of capital is 10% and the following values should be used: GHS Value of GHS1 at: End of year 1 0.91 End of year 2 0.83 End of year 3 0.75 b) DT ltd owns a 100% subsidiary, S, that is treated as a cash generating unit. On 31 March 2012, there was an industrial accident (a gas explosion) that caused damage to some of S's plant. The assets of T immediately before the accident were: GHS'000 Goodwill 1,800 Patent 1,200 Factory building 4,000 Plant 3,500 Receivables and cash 1,500 12,000 As a result of the accident, the recoverable amount of S is GHS6.7m. The explosion destroyed (to the point of no further use) an item of plant that had a carrying amount of GHS500,000. S has an open offer from a competitor of GHS1m for its patent. The receivables and cash are already stated at their fair values less costs to sell (net realisable values). Required: Calculate the carrying amounts of the assets in (i) and (ii) above at 31 March 2012 after applying any impairment losses
