5. The equipment to be used on the contract cost£80,000 five years ago. It wasplanned to keep it for ten years after which its scrap value was expected to be£10,000. The depreciation charge in the cost estimate is based on this data. Atpresent, the equipment is worth£30,000. If used on the contract, its realisablevalue is likely to decline to about£28,000. The company has no further use forthe equipment and, if the contract is not accepted, they would sell it now.6. The new contract is so specialised that it has now been realised that one of thesupervisors will have to be recruited from a competitor. She will be expected tobe paid a premium salary of£2,000 per month. The second supervisor, who iscurrently paid£1,000 per month, can be transferred from another department.However, he will only transfer to the project if he is offered a one-off bonuspayment of£500. His role will be replaced by a temporary upgrading of anexisting worker which is estimated to cost an additional£200 per month.7. The management accountant has allowed fixed overheads for the contract usingthe company’s pre-determined policy of 40% of direct labour. The general fixedoverhead recovery rate consists of allocated rent, rates, general expenses andsimilar fixed costs. However, it is anticipated that this additional contractwould make general expenses increase by£500 per month for the duration ofthe contract.Required:(a) Define opportunity cost.(2 marks)(b) Prepare a revised cost estimate for the contract in the light of the aboveinformation. Clearly explain for each item why your calculations differ from theoriginal estimate submitted by the management accountant.(19 marks)(c) Identify two other considerations which should be taken into account indeciding whether to tender for the contract.(4 marks)Reading for this questionSubject guide, Chapter 10.Perks, R. and D.
