An auditor is evaluating the overall reasonableness of a client's financial statements using analytical procedures. The client operates in a highly competitive retail industry. Which of the following relationships would generally be expected to be most predictable for this type of client?
- AThe relationship between interest expense and long-term debt.
- BThe relationship between advertising expense and sales revenue.
- CThe relationship between depreciation expense and property, plant, and equipment.
- DThe relationship between research and development expense and future sales.
Show answer & explanationAnswer & explanation
Correct answer: C. The relationship between depreciation expense and property, plant, and equipment.
The relationship between depreciation expense and property, plant, and equipment (PP&E) is typically highly predictable. Depreciation is a systematic allocation based on fixed asset balances and established depreciation policies (useful lives, salvage values, methods). Unlike revenue or R&D, which are influenced by complex and unpredictable external factors, PP&E and depreciation are largely internal and stable over short periods, making this relationship very reliable for analytical procedures.
Why the other options are wrong
- A. While interest expense and long-term debt are related, interest rates can fluctuate, and debt covenants or new borrowings/repayments can introduce variability, making it somewhat less predictable than depreciation.
- B. Advertising effectiveness can vary highly in competitive industries, making the relationship with sales revenue less predictable.
- D. The link between R&D spending and future sales is inherently uncertain and long-term, making it very unpredictable for short-term analytical procedures.
Predictability of Relationships for Analytical Procedures
The effectiveness of analytical procedures depends on the predictability of relationships between data. Relationships that are stable over time, less influenced by discretion, and derived from a consistent, systematic process are generally more predictable.
- Relationships involving income statement accounts are often less predictable than balance sheet accounts, especially those affected by management discretion or external factors.
- Relationships within the same accounting cycle (e.g., sales and receivables) can be predictable.
- Non-discretionary expenses (e.g., depreciation, rent) tend to be more predictable than discretionary ones (e.g., advertising, R&D).
- Relationships in stable environments are more predictable than in volatile or competitive environments.
Memory trick: PREDICTABLE relationships are STABLE, not SUBJECTIVE or EXTERNAL.
