Birch Company normally produces and sells 40,000 units of RG-6 each month. RG-6 is a small electrical relay used in the automotive industry as a component part in various products. The selling price is $42 per unit, variable costs are $34 per unit, fixed manufacturing overhead costs total $200,000 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 Companys sales to temporarily drop to only 28,000 units per month. Birch Company estimates that the strikes will last for about two months, after which time sales of RG-6 should return to normal. Due to the current low level of sales, however, Birch Company is thinking about closing its own plant during the two months that the strikes are on. If Birch Company does close its plant, it is estimated that fixed manufacturing overhead costs can be reduced to $140,000 per month and that fixed selling costs can be reduced by 10%. Startup costs at the end of the shutdown period would total $28,000. Since Birch Company uses just-in-time production methods, no inventories are on hand.
