RG produces a specialised building tool in three factories throughout Ireland. The output produced in the Dublin, Cork and Belfast factories per year is 88 000, 52 800, and 35 200 units, respectively. This level of output represents the typical level of output. The specialised building tool is sold to customers for 8 per unit. The profit or loss for the last financial year is shown below: Sales () Dublin Cork Belfast Total 704 000 422 400 281 600 1 408 000 Cost of sales () 264 000 158 400 105 600 528 000 Gross profit () 440 000 264 000 176 000 880 000 Factory costs () 220 000 112 000 104 000 436 000 Administration costs () 84 000 54 000 50 000 188 000 Depreciation of factory equipment () 60 000 36 000 24 000 120 000 Total operating costs 364 000 202 000 178 000 744 000 Operating profit/loss 76 000 62 000 (2 000) 136 000 As a result of the loss showing in the Belfast factory, RG is considering various options as follows: Option 1: RG would make no changes and keep all factories open. Option 2: RG would close the Belfast factory. Under this option, the production in the other two factories (Dublin and Cork) would remain unchanged. Option 3: RG would close the Belfast factory but move some of the Belfast production to the Cork factory and outsource some additional output. Under this option the Cork factory would take 20% of the existing Belfast production (that is, 7 040 units), and outsource 20 000 units from an external supplier outside Ireland. RG can purchase 20 000 units from the external supplier for 6 per unit. Production in the Dublin factory would remain unchanged. The following additional information is available: 1. The cost of sales consists of the variable costs to produce the building tool, including direct materials (1 per unit) and specialised direct labour required to build the tool (2 per unit). 2. The factory and administration costs are fixed costs associated specifically with each factory 3. The depreciation of factory equipment (120 000) is a corporate level cost that is allocated to the factories proportionally based on the output produced.
