Barbour Corporation, located in Buffalo, New York, is a retailer of high-tech products and is known for its excellent quality and innovation. Recently, the firm conducted a relevant cost analysis of one of its product lines that has only two products, T-1 and T-2. The sales for T-2 are decreasing and the purchase costs are increasing. The firm might drop T-2 and sell only T-1. Barbour allocates fixed costs to products on the basis of sales revenue. When the president of Barbour saw the income statements (see below), he agreed that T-2 should be dropped. If T-2 is dropped, sales of T-1 are expected to increase by 10% next year, but the firm's cost structure will remain the same. T-1 T-2 Sales $280, 000 $324, 000 Variable costs: Cost of goods sold 86, 000 162, 000 Selling & administrative 12, 000 66,000 Contribution margin $182, 000 $ 96, 000 Fixed expenses: Fixed corporate costs 76, 000 91, 000 Fixed selling and administrative 28, 000 37,000 Total fixed expenses $104, 000 $128, 000 Operating income $ 78, 000 $ (32, 000) Required: 1.
