    -Skilled labour is hard to recruit
    -The workers concerned were transferred to the contract from production department and at a recent meeting, the production manager claimed that if the men were returned to him they could generate sales of $150,000 in the next year

    The prime cost of these sales would $100,000 including $40,000 for the labour cost itself

    The overhead absorbed into this production would amount to $20,000

    Sir, I don’t have problem to calculate the relevant costing which is $90,000. The only problem I have is why we deduct it instead of adding it?

    You have not said what it is being deducted from, and so without seeing the whole question I cannot really answer you.

    A research contract, which to date has cost the company $150,000, is under review.

    If the contract is allowed to proceed:

    it will be completed in approximately one year
    the results would then be sold to a government agency for $300,000.
    Shown below are the additional expenses which the managing director estimates will be necessary to complete the work.

    Materials

    This material for the contract has just been purchased at a cost of $60,000.
    It is toxic; if not used in this contract it must be disposed of at a cost of $5,000.
    Labour

    Skilled labour is hard to recruit.
    The workers concerned were transferred to the contract from a production department, and at a recent meeting, the production manager claimed that if the men were returned to him they could generate sales of $150,000 in the next year.
    The prime cost of these sales would be $100,000, including $40,000 for the labour cost itself.
    The overhead absorbed into this production would amount to $20,000.
    Research staff

    It has been decided that when work on this contract ceases, the research department will be closed.
    Research wages for the year are $60,000, and redundancy and severance pay has been estimated at $15,000 now, or $35,000 in one year’s time.
    Equipment

    The contract utilises a special microscope which cost $18,000 three years ago.
    It has a residual value of $3,000 in another two years, and a current disposal value of $8,000.
    If used in the contract it is estimated that the disposal value in a year’s time will be $6,000.
    Share of general building services

    The contract is charged with $35,000 pa to cover general building expenses.
    Immediately after the contract is discontinued, the space occupied could be sub-let for an annual rental of $7,000.
    Required:

    Advise the managing director as to whether the contract should beallowed to proceed, explaining the reasons for the treatment of eachitem.

    (Note: Ignore the time value of money.)

    My question is about the skilled labour which is $90,000. According to the answer we have to deduct it.

    Why we have to deduct it and not adding it instead?

    It is because taking the skilled labour for the contract is an opportunity cost of doing the contract – it is losing contribution that otherwise would be earned.

    Have you watched my free lectures on relevant costing?

    Yes, I did watch your lecture and I understand that this is an opportunity cost. I calculated it correctly.

    However, when I look at the answer given.

    (1)Costs to date of $150,000 sunk-Ignore
    (2)Materials $5,000
    (3)Labour cost ($90,000)
    (4)Research staff costs ($60,000)
    Wages for the year ($20,000)
    (5)equipment ($8,000)
    Deprival value if used in the project $6,000
    (6)general building services ($7,000)
    -Total relevant cash flow associated with the contract ($174,000)
    -Sales Value of contract $300,000
    -Increased contribution from contract $126,000

    I know how to calculate the opportunity cost for the labour which is $90,000.my problem is when we calculate the total relevant cash flow associated with the contract above, I don’t understand why we deduct the $90,000 for the labour cost? Is it because we saved money?

    As I wrote before, they are an opportunity cost because the company is losing contribution. Therefore they have been added in to arrive at the figure for the total relevant costs os 174,000.
