Distinguishing direct vs. indirect labour for accurate overhead absorption

Steps:

• In absorption costing, overheads are absorbed using a predetermined rate based on direct labour hours only.
• Direct labour is traceable to products; indirect labour is part of overhead costs, not the absorption base.
• Distinguishing ensures the absorption rate (total overheads ÷ budgeted direct labour hours) accurately reflects product costs.
• This precise costing supports full cost pricing, directly aiding quote preparation.

Why A is correct:

• Absorption costing formula requires overhead rate = budgeted overheads ÷ budgeted direct labour hours; distinguishing labour types ensures only direct hours are used as the base for product costing in quotes.

Why the others are wrong:

• B includes 2 and 3, but production planning and material purchasing do not rely on labour type distinction for overhead absorption.
• C omits 1; planning and purchasing are unrelated to calculating direct labour-based rates.
• D ignores 1 and 2; purchasing materials involves costs unrelated to labour classification.

Final answer: A
