To advise the managing director on whether the research contract should proceed, we need to identify and quantify all relevant costs and benefits. Relevant costs are future, incremental cash flows that differ between the decision to proceed and the decision to discontinue. Sunk costs (past costs) and unavoidable fixed costs are irrelevant. Step 1: Identify and explain the treatment of each item. Contract cost to date (GH¢150,000): This is a sunk cost* incurred in the past. It is irrelevant to the current decision of whether to proceed, as it cannot be recovered or changed by any future action. Revenue from selling results (GH¢300,000): This is a future cash inflow that will only be realized if the contract proceeds. Therefore, it is a relevant benefit*. Materials: Cost of material just purchased (GH¢60,000): This is a sunk cost* as it has already been incurred. It is irrelevant to the decision. Disposal cost if not used (GH¢5,000): If the contract proceeds, the company avoids this GH¢5,000 disposal cost. Avoiding a cost is a benefit. Therefore, GH¢5,000 is a relevant benefit* of proceeding. Skilled labour: The workers, if returned to the production department, could generate sales of GH¢150,000 with a prime cost of GH¢100,000. The contribution foregone from this alternative work is GH¢150,000 (sales) - GH¢100,000 (prime cost) = GH¢50,000. This is an opportunity cost* of using the skilled labour for the research contract. The overhead absorbed into this production (GH¢20,000) is likely a fixed overhead allocation and not an incremental cash outflow. Therefore, it is irrelevant. Relevant cost: GH¢50,000. Research staff: Research wages for the year (GH¢60,000): This is a future cash outflow that will be incurred only if the contract proceeds for another year. Therefore, it is a relevant cost*. Redundancy and severance pay: If the contract is discontinued now, the cost is GH¢15,000. If the contract proceeds for one year, the cost will be GH¢35,000. The incremental cost of redundancy if the contract proceeds is GH¢35,000 - GH¢15,000 = GH¢20,000. This is a relevant cost*. Total relevant cost: GH¢60,000 + GH¢20,000 = GH¢80,000. Equipment (Microscope): Original cost (GH¢18,000) and residual value in two years (GH¢3,000) are irrelevant (sunk cost and future value not directly impacted by this one-year decision). Current disposal value (GH¢8,000): This is the amount that could be received if the microscope is sold now. Disposal value in one year (GH¢6,000): This is the amount that could be received if the microscope is used for the contract and then sold. The opportunity cost of using the microscope for the contract is the reduction in its disposal value: GH¢8,000 (current sale) - GH¢6,000 (future sale) = GH¢2,000. This is a relevant cost*. Share of general building services: Charged GH¢35,000 pa: This is a fixed cost that will be incurred regardless of the decision to proceed or discontinue the contract. Therefore, it is irrelevant. Annual rental if space is sublet (GH¢7,000): If the contract proceeds, the company foregoes this potential rental income. This is an opportunity cost* of proceeding. Relevant cost: GH¢7,000. Step 2: Calculate the net financial impact of proceeding with the contract. Benefits of Proceeding: Revenue from selling results: GH¢300,000 Avoided material disposal cost: GH¢5,000 Total Benefits: GH¢305,000 Costs of Proceeding: Opportunity cost of skilled labour: GH¢50,000 Research staff wages: GH¢60,000 Incremental redundancy cost for research staff: GH¢20,000 Opportunity cost of microscope: GH¢2,000 Opportunity cost of building space: GH¢7,000 Total Costs: GH¢139,000 Net Benefit of Proceeding = Total Benefits - Total Costs Net Benefit = GH¢305,000 - GH¢139,000 = GH¢166,000 Step 3: Advise the managing director. Since the net benefit of proceeding with the contract is positive (GH¢166,000), the managing director should allow the contract to proceed. The final answer is The managing director should allow the contract to proceed, as it yields a net benefit of GH¢166,000. 3 done, 2 left today. You're making progress.
