Portia Ltd is a specialist manufacturer of components for luxury yachts. A contract has been offered to Portia by Nerrisa Supermarine plc for the supply over the next twelve months of 400 identical components, ZK44. The data relating to the production of each component ZK44 is as follows: (1) Material requirements: (2) (3) (a) 3 kg material M1 - see note (i) below. 2 kg material P2 - see note (ii) below 1 part No. 678 - see note (iii) below. (b) Note (i) Material M1 is in continuous use by the company. 1,000 kg are currently held in stock at a book value of 4.70 per kg but it is known that future purchases will cost 5.50 per kg. Note (ii) 1,200 kg of material P2 are held in stock. The original cost of this material was 4.30 per kg but, as the material has not been required for the last two years, it has been written down to 1.50 per kg scrap value. The only foreseeable alternative use is as a substitute for material P4 (in current use) but this would involve further processing costs of 1.60 per kg. The current cost of material P4 is 3.60 per kg. Note (iii) It is estimated that Part No. 678 could be bought for 50 each. Labour requirements: Each component would require five hours of skilled labour and five hours of semi-skilled. An employee possessing the necessary skills is available and is currently paid 5 per hour. A replacement would, however, have to be obtained at a rate of 4 per hour for the work which would otherwise be done by the skilled employee. The current rate for semi-skilled work is 3 per hour and an additional employee could be appointed for this work. Overhead: Portia Ltd absorbs overhead by a machine hour rate, currently 20 per hour of which 7 is for variable overhead and 13 for fixed overhead.
