Which concept requires using uniform accounting methods from period to period, with changes clearly explained?

• A. Materiality
• B. Adequate Disclosure
• C. Historical Cost
• D. Consistency

Answer: (D)

Consistency means using the same accounting methods from one period to the next so financial statements stay comparable over time. When a change in method is necessary, it must be clearly explained in the notes, along with its effect on the financial statements, so users can understand and adjust their comparisons.

This differs from materiality, which is about whether an item is significant enough to disclose; adequate disclosure, while important for transparency, focuses on providing sufficient information rather than enforcing uniform methods; and historical cost, which is a measurement basis based on the original purchase price, not the requirement to apply the same method year after year with explanations for changes.
