The Allocation of Unabsorbed Overhead
Unabsorbed overhead costs can occur in many circumstances, including business cycles that experience reduced activity and hence results in lower absorption of costs than planned. These unabsorbed costs can include raw materials, spare parts, payroll costs, indirect labor, administrative expenses, etc. When the cause of the unabsorbed costs can be identified and definitively attributed to one or more business units or divisions, the way in which the costs are allocated is to determine the proper amount to be allocated to the respective business unit.
Methods for allocating unabsorbed overhead costs depend on the circumstances causing the unabsorbed costs, the amount involved and the impact of the allocation among the divisions or business units within the organization. One of the more common methods is to use a prorated basis which takes into consideration the unit’s level of contributions to the overhead costs. This may be determined by sales, production levels or other measure of activity. Other factors may be considered, such as the degree of control exercised by the unit over the costs or the cost sensitivity of the unit.
Another method for allocating unabsorbed overhead costs is to use a gradual approach, where the costs are spread over a multi period in a systematic manner. This approach helps to reduce the impact of large unabsorbed costs and allows for more equitable sharing of the burden among the respective divisions or business units. For example, if there were $100,000 in unabsorbed costs that was determined to be spread out over four periods, the cost allocation would be $25,000 for each period.
The last method of allocating unabsorbed overhead is the lump-sum approach, which requires that each affected division or business unit accept a portion of the unabsorbed costs based on the activity or contribution in proportion to the other divisions. This approach may be suitable when the cause of the unabsorbed costs is difficult to measure, such as sudden and unexpected changes in the marketplace. However, the lump-sum method of allocation is often unfair because the least affected unit may be forced to absorb more than its pro rata share of the unabsorbed costs.
Regardless of the method chosen, it is essential that the allocation of unabsorbed overhead costs be fair, equitable and properly supported. The allocation process should be well documented and reviewed by all parties involved, both before and after the process is completed. The allocation should also be in accordance with accepted accounting principles, including any specific guidelines prescribed by the applicable organization or external body.
In conclusion, the allocation of unabsorbed overhead costs is a critical task for any organization experiencing this situation. When properly done, the allocation of unabsorbed overhead cost can serve to fairly, equitably, and systematically spread the burden among the respective business units. Establishing and documenting the appropriate allocation of unabsorbed overhead costs is essential in order to ensure accuracy, reduce risk, and provide a clear understanding of the financial impact of the situation.
