1. Analyzing Unprofitable Product Segments
When a departmental performance report shows a product line, branch office, or store location running at a net loss, management’s first instinct is often to close it down immediately. This can be a costly mistake if the decision is based on traditional absorption reports.
2. The Contribution Margin Assessment Rule
A segment should only be shut down if the contribution margin it generates is lower than the specific fixed costs that would be completely eliminated by its closure.

   SEGMENT DISCONTINUATION ANALYSIS EVALUATION
=============================================================================
  Reported Segment Sales Revenue:                     $ 100,000
  Less: Total Variable Operating Costs:              ($  70,000)
                                                      ---------
  Segment Contribution Margin:                        $  30,000  <-- POSITIVE MARGIN
  Less: Allocated General Corporate Head Office Rent: ($  45,000)
                                                      ---------
  Reported Accounting Net Profit / (Loss):           ($  15,000)
=============================================================================

Financial Diagnostic: Although this segment reports an accounting loss of $15,000, it contributes $30,000 toward covering the company’s shared corporate rent. Because the corporate rent bill will not change if the branch closes, shutting down this segment will cause total corporate net profits to drop by $30,000. The segment should remain open.
3. Non-Financial Shut Down Factors
Before finalizing a shutdown or product discontinuation, management must look beyond the numbers and consider long-term business impacts:
  • Product Complementarity: Discontinuing a low-margin product (like razor handles) might ruin sales for a high-margin companion product (like replacement razor blades).
  • Customer Goodwill: Closing a regional branch office can alienate loyal long-term clients and damage the company’s reputation.
  • Staff Severance Costs: Immediate layoffs can trigger expensive legal severance packages and damage remaining employee morale.
