Mambosasa Ltd. makes special-purpose equipment according to customer specifications. During the past year, one of its loyal customers, Monga Ltd., ordered specialized equipment to be fabricated for it. Mambosasa Ltd. finished the fabric of the equipment only to be notified that Monga Ltd, had recently gone into liquidation and will not therefore take the equipment.
The original price to Monga Ltd. had been agreed at TZS.182,160,000 which included an estimated normal profit mark up of 10% on total costs. The costs incurred to manufacture the equipment were:
TABLE
DETAILS | TZS. |
---|---|
Direct materials | 68,400,000 |
Direct wages | 43,200,000 |
Variable overheads | 10,800,000 |
Fixed production | 36,000,000 |
Fixed selling and administration | 7,200,000 |
total | 165,600,000 |
After a sustained search, the sales manager of Mambosasa Ltd has managed to locate one potential buyer, Zedwi Systems Ltd, which has indicated that it could buy the equipment if certain conversion work could be carried out.
Mambosasa Ltd's production department has made a preliminary assessment which reveals that conversion would entail extra work cost as follows:
Direct materials TZS.11,520,000.
Direct wages:
Department X: 3 men for 4 weeks at TZS.540,000 per man/week.
Department Y: 1 man for 4 weeks at TZS.432,000 per man/week.
Variable overhead: 20% of direct wages.
Fixed production overhead:
Department X: 75% of direct wages.
Department Y: 25% of direct wages.
The following additional information is provided:
- In the original equipment, there were three types of basic materials; type P, Q and R.
- Type P could now be sold to a scrap merchant for TZS.10,800,000.
- Type Q could be sold to a scrap merchant for TZS.7,200,000 but it would take 120 hours of labour paid at TZS.5,400 per hour to put it into a suitable condition for sale.
- Type R would need to be scrapped to Mambosasa Ltd. at a cost of TZS.2,160,000.
- The materials for the conversion are at present in stock. If not needed for the conversion they could be used in the production of another equipment in place of materials that would currently cost TZS.13,680,000.
- The conversion would be carried out in two departments
Department X is currently extremely busy and it is estimated that its contribution overheads and profits is TZS.50 for every TZS.1 of labour.
Department Y has idle staff, for organizational reasons its labour force cannot be reduced below its present level of four employees, all of whom are paid at the standard rate of TZS.432,000 per week. - The designs and specification of the original equipment could be sold in a neighboring country for a sum of TZS.5,400,000 if the machine is scrapped.
- An additional temporary supervisor would have to be engaged for the conversion work at a cost of TZS.3,240,000. It is the company's normal practice to charge supervision as fixed overhead.
- Monga Ltd. had paid Mambosasa Ltd. a non-returnable deposit of 12% of the selling price.
REQUIRED:
- Determine the minimum price that Mambosasa Ltd. should accept from Zedwi System Ltd, for the converted equipment and explain clearly how will you arrive at your figure by justifying the relevance of each item. (15 marks)
- Explain clearly any assumptions that you have made in arriving at your conclusions in (1) above. (5 marks)
