Activity-Based Costing (ABC) is a cost allocation method that assigns overhead costs based on activities that drive costs rather than using a single volume-based measure like labor hours or machine hours. It provides a more accurate allocation of indirect costs to products or services.
* ABC Costing and Its Flexibility (Correct Answer: C)
* ABC can be applied to both job order costing (which tracks costs for individual products or projects) and process costing (which tracks costs across continuous production processes).
* IIA Standard 2120 - Risk Management suggests that internal auditors evaluate whether cost allocation methodologies align with business objectives and financial accuracy.
* ABC improves cost accuracy by assigning overhead to specific activities, making it useful in different costing systems.
* Why the Other Options Are Incorrect:
* A. "ABC is similar to conventional costing in how it treats overhead allocation." (Incorrect)
* Traditional costing allocates overhead based on a single cost driver, such as direct labor or machine hours.
* ABC allocates overhead based on multiple activity drivers, making it more precise.
* B. "ABC uses a single unit-level basis to allocate overhead." (Incorrect)
* ABC does not rely on a single unit-level measure.
* Instead, it uses multiple cost drivers at different levels (unit-level, batch-level, product- level, and facility-level).
* D. "The primary disadvantage of ABC is less accurate product costing." (Incorrect)
* ABC is actually more accurate than traditional costing in assigning overhead costs.
* The primary disadvantages of ABC are its complexity and cost of implementation, not reduced accuracy.
* IIA Standard 2120 - Risk Management (Assessing the appropriateness of costing methodologies)
* IIA Standard 2130 - Compliance (Ensuring financial management practices align with standards)
* IIA Standard 2210 - Engagement Objectives (Evaluating financial controls and cost allocation methods) Step-by-Step Justification:IIA References for This Answer:Thus, the best answer is C. An ABC costing system may be used with either a job order or a process cost accounting system, as ABC is flexible and can be applied in both costing environments.
