Segment Elimination Decisions: Videos & Practice Problems
Segment Elimination Decisions focus on whether a poorly performing division should be removed from the company. The key is to separate avoidable costs from unavoidable costs. Avoidable costs are costs that disappear if the segment is eliminated, including all variable costs and any fixed costs tied directly to that segment. Unavoidable costs remain even if the segment is dropped, so they are not removed from the company’s total cost structure.
A contribution margin income statement is especially useful because it separates variable and fixed costs. The segment’s contribution margin shows how much is available to cover fixed costs. For elimination decisions, a fixed cost is relevant only if it is avoidable. The central decision rule is $CM < AFC$ . If contribution margin is greater than avoidable fixed costs, dropping the segment lowers total company income because unavoidable fixed costs still remain.

Segment Elimination Decisions
When deciding whether to eliminate a segment, a fixed cost is relevant to the decision only if it is:
a fixed cost that will continue regardless of the decision.
an avoidable cost that would be eliminated along with the segment.
a cost that has already been incurred in a prior period.
an unavoidable cost that will be reallocated to other segments.
Here's what students ask on this topic:
Avoidable costs are expenses that disappear if a segment is eliminated. These include all variable costs, such as labor wages directly tied to the segment, and some fixed costs that are specific to that segment, like rent for a studio used only by that division. Unavoidable costs, on the other hand, remain even if the segment is removed. These are fixed costs that support other parts of the company and cannot be eliminated, such as office rent for shared services like legal or IT. Understanding the difference is crucial because only avoidable costs are relevant when deciding whether to drop a segment. This helps managers evaluate if removing a segment will truly reduce costs or just shift them elsewhere.
A contribution margin income statement separates variable costs from fixed costs, making it easier to analyze segment profitability. The contribution margin is calculated as sales minus variable costs and shows how much money is available to cover fixed costs. When considering segment elimination, this statement helps identify the segment's contribution margin and compare it to avoidable fixed costs. If the contribution margin is greater than avoidable fixed costs, removing the segment would reduce overall company income because unavoidable fixed costs remain. Thus, this income statement is a valuable tool for managers to make informed decisions about whether to keep or eliminate a segment.
The key rule for segment elimination is to compare the segment's contribution margin (CM) to its avoidable fixed costs (AFC). The decision rule is: eliminate the segment if . This means if the contribution margin is less than the avoidable fixed costs, the segment is not covering the costs that would disappear if it were removed, so eliminating it will increase overall company income. Conversely, if the contribution margin is greater than avoidable fixed costs, removing the segment would lower total income because unavoidable fixed costs still need to be paid elsewhere.
A segment showing negative income might still be retained if its contribution margin exceeds its avoidable fixed costs. This happens because some fixed costs are unavoidable and must be absorbed by other segments if the segment is eliminated. Removing the segment would eliminate its contribution margin but not all fixed costs, causing the overall company income to decrease. Therefore, even if a segment appears unprofitable on the surface, it can still contribute positively to the company's total income by covering part of the unavoidable fixed costs.
When a segment is eliminated, unavoidable fixed costs associated with that segment do not disappear; instead, they must be allocated to the remaining segments. This allocation can be done by dividing the unavoidable fixed costs among the other segments, often based on a reasonable method such as equal distribution or proportional to sales or contribution margin. This reallocation increases the fixed costs of the remaining segments, which can affect their profitability. Understanding this helps managers see the full financial impact of eliminating a segment beyond just the lost sales and variable costs.
