Inventory Audit Procedures: Existence and Obsolescence

Answer A. The auditor's assessed risks of material misstatement primarily determine the nature, timing, and extent of further procedures. High inherent risk for valuation requires more persuasive substantive procedures (greater extent and more reliable evidence) regardless of control design until the operating effectiveness of those controls has been tested and supports reduced substantive work.

Why not B: This is tempting because effective inventory controls can reduce the need for substantive testing; however, control design or appearance of effectiveness cannot be relied on until the auditor tests and concludes the controls are operating effectively, so design alone should not govern selection of procedures.

Why not C: This distractor tempts because more reliable evidence is preferred, but reliability is a secondary consideration, first the auditor must determine how persuasive the evidence must be based on assessed risks, and then choose evidence sources that meet that required persuasiveness.

Why not D: Cost and practicality may influence the choice among acceptable procedures, which is why auditors consider them, but they cannot override the need to obtain sufficient appropriate evidence as required by the assessed risks of misstatement.

Answer C. The November market change materially increased the risk of misstatement for existence and valuation (obsolescence) at December 31, so interim testing alone is no longer sufficient. The auditor must obtain evidence that covers the period from the interim observation through year‑end, either by performing roll‑forward procedures, performing a year‑end count, or using appropriate alternative procedures, and must perform additional valuation testing (for example, testing subsequent sales, reviewing price reductions, and evaluating management's allowance). These steps provide the necessary corroborating evidence over cut‑off, existence, and valuation at year‑end.

Why not A: Tempting because prior controls and an interim count reduce audit effort, but incorrect because the significant market change occurred after the interim date; those procedures do not provide evidence over the intervening period or on valuation at year‑end.

Why not B: Analytical procedures are useful screening tools but are generally insufficient alone to provide persuasive evidence about existence or detailed valuation (obsolescence) when significant market changes occurred after the interim count; physical observation or appropriate alternative substantive procedures are needed.

Why not D: Written representations and schedules do not substitute for independent, corroborating audit evidence when risk increased; relying solely on management's adjustments without substantive testing (for example, subsequent sales testing or review of pricing) would be inappropriate.

Answer A. Inquiry and analytical procedures are valid but generally provide indirect evidence. For a significant inventory balance with obsolescence risk, auditors ordinarily need more direct evidence (for example, observation, inspection, physical counts, or price testing) to support existence and valuation. Analytics and management inquiry can supplement but typically do not replace those direct procedures.

Why not B: This is tempting because both procedures are legitimate; however, the question asks whether they are persuasive enough alone. For significant, obsolescence-prone inventory, those procedures by themselves are usually not sufficient to provide appropriate audit evidence.

Why not C: Relying on a knowledgeable employee's inquiry is risky because management representations are less persuasive than direct observation or counts. Without inspection or test counts, existence is not adequately supported despite the production manager's knowledge.

Why not D: A consistent gross profit percentage can support overall reasonableness but does not provide direct evidence of physical existence or the absence of obsolescence. Analytical results are complementary and cannot generally substitute for direct inventory procedures when obsolescence is a risk.

Answer A. With weak controls and clear indicators of aged inventory, the valuation assertion is at high risk and requires persuasive, item‑level evidence. Testing individual aged items (cost records, vendor price lists, subsequent sales) directly assesses whether cost exceeds NRV and supports recalculating an appropriate obsolescence reserve. Analytical procedures, confirmations, or a specialist alone would not be the best initial means to obtain sufficient appropriate evidence here.

Why not B: This is tempting because analytical procedures are efficient and may suggest overall trends, but they do not provide the item‑level, persuasive evidence needed when controls are weak and specific aged items exist. Analytical work alone would not adequately test NRV or identify obsolete items.

Why not C: A specialist can be useful for unusually complex valuations, but ordinary electronic components typically allow the auditor to obtain direct evidence (cost tests, vendor prices, subsequent sales). Engaging a specialist as the first step is unnecessary unless the valuation is technically beyond the auditor's expertise.

Why not D: External confirmations provide independent evidence about terms or whether transactions occurred, but they do not directly establish net realizable value or the extent of obsolescence. Confirmations would be complementary at best and would not substitute for item‑level NRV testing.

Answer A. Because quantity has already been tested, the remaining concern is valuation (possible obsolescence or NRV). Reviewing an aging schedule and comparing slow-moving items to subsequent selling prices directly tests whether those items can be sold for at least their recorded amounts. Subsequent selling prices are persuasive, direct evidence for valuation.

Why not B: This is tempting because inventory issues often suggest count procedures, but recounting and tracing primarily provide evidence about existence and completeness. The stem states quantity evidence is already satisfactory, so this procedure would not address valuation or NRV.

Why not C: A management representation supports other evidence but is less reliable than substantive testing and cannot substitute for direct valuation procedures. It may be obtained in addition to testing but does not provide persuasive evidence about realizable value.

Why not D: Analytical review of turnover can identify indicators of obsolescence but is indirect. Investigating changes helps locate risk areas but does not directly test whether specific slow-moving items are valued at the lower of cost and net realizable value; examining aging and subsequent sales is more conclusive.
