Cool Rays Ltd. is considering dropping its Tinted Glass product line. The Tinted Lens product line income statement for the last year was as follows:

The company has a total of 3 product lines. Only $200,000 of fixed manufacturing costs can be eliminated if the Tinted Lens product line is discontinued. The balance of the fixed manufactured costs have been allocated to the product line on the basis of sales.
Should Cool Rays drop the Tinted Glass product line? By how much would operating income increase or decrease if the product line is dropped? Show your work.
Irrespective of your calculation above, very briefly list two other considerations that should influence senior management's decision in decisions of this type?
Regardless of your answer above, assume the company would lose $200,000 if the Tinted Lens product line were dropped. Also assume that if the Tinted Glass product line was dropped the company could introduce a new product line Z, which is quite unique in the market place. The following information relates to this possibility:
Sales of product line Z........................................$1,000,000
Variable manufacturing costs.....................50% of selling price
Sales commissions.................................10% of selling price
Required advertising for product line Z.......................$75,000
The amount allocated to product line Z for fixed manufacturing expenses and head office expenses would remain the same.
