Question

Birch Company normally produces and sells 41,000 units of RG-6 each month. The selling price is $30 per unit, variable costs are $10 per unit, fixed manufacturing overhead costs total $160,000 per month, and fixed selling costs total $40,000 per month.

Employment-contract strikes in the companies that purchase the bulk of the RG-6 units have caused Birch Company’s sales to temporarily drop to only 11,000 units per month. Birch Company estimates that the strikes will last for two months, after which time sales of RG-6 should return to normal. Due to the current low level of sales, Birch Company is thinking about closing down its own plant during the strike, which would reduce its fixed manufacturing overhead costs by $46,000 per month and its fixed selling costs by 10%. Start-up costs at the end of the shutdown period would total $13,000. Because Birch Company uses Lean Production methods, no inventories are on hand.

Required:

1. What is the financial advantage (disadvantage) if Birch closes its own plant for two months?

2. Should Birch close the plant for two months?

3. At what level of unit sales for the two-month period would Birch Company be indifferent between closing the plant or keeping it open?

Answer 1

Solution 1:

Differential Analysis - Continue plant for 2 months (alt 1) or Shutdown plant for 2 months (Alt2)
Particulars	Continue plant for 2 months (Alt 1)	Shut down plant for 2 months (Alt 2)	Increase (Decrease) in income of shutdown (Alternative 2)
Revenue (11000*2*$30)	$6,60,000	$0	-$6,60,000
Costs:
Variable cost (11000*2*$10)	$2,20,000	$0	$2,20,000
Fixed manufacturing overhead cost	$3,20,000	$2,28,000	$92,000
Fixed selling cost	$80,000	$72,000	$8,000
Startup cost at the end of shutdown period	$0	$13,000	-$13,000
Income / (Loss)	$40,000	-$3,13,000	-$3,53,000

Financial disadvantage = - $353,000

Solution 2:

No, Birch should not close the plant for two months.

Solution 3:

Level of sales to be indifferent = (Avoidable Fixed Cost - Startup cost) / Contribution margin per unit

= ($92000+ $8000 - $13000) / ($30- $10)

= $87,000 / $20

= 4350 units
