Members of the board of directors of Security Systems have received the following operating income data for the year just ended:

Members of the board are surprised that the industrial systems product line is losing money. They commission a study to determine whether the company should drop the line. Company accountants estimate that dropping industrial systems will decrease fixed cost of goods sold by $80,000 and decrease fixed marketing and administrative expenses by $12,000.
Requirements
1. Prepare an incremental analysis to show whether Security Systems should drop the industrial systems product line.
2. Prepare contribution margin income statements to show Security Systems€™ total operating income under the two alternatives: (a) With the industrial systems line and (b) Without the line. Compare the difference between the two alternatives€™ income numbers to your answer to Requirement 1. What have you learned from this comparison?
