MB-330 Implement Inventory and Asset Management Practice Question
You are configuring inventory valuation for a company that requires precise tracking of specific item costs. You must ensure that the inventory valuation method allows for reversing transactions while maintaining cost accuracy. Which inventory model should you select?
⚠ Common exam trap
Candidates often select 'FIFO' or 'Weighted Average', failing to realize these methods do not track the cost of specific individual units, making them unsuitable for precise cost reconciliation.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Specific identification
The 'Specific identification' method is the only option that tracks the exact cost of each individual item. This is critical for high-value assets where actual cost must be reconciled against the specific purchase price. By using this method, the system ensures that when an item is issued or returned, the cost of that exact unit is reflected in the ledger, preventing inventory valuation drift.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
FIFO
Why it's wrong here
FIFO assumes that items purchased first are sold first, which does not allow for identifying the specific cost of a unique unit. This model is useful for inventory flow management but fails to satisfy requirements where unique cost tracking per serial number or specific unit is mandated.
- ✗
Weighted average
Why it's wrong here
Weighted average calculates a moving average cost based on all receipts, which effectively masks the individual cost of specific items. While this is a standard accounting method, it cannot isolate the exact cost of a unique item, making it unsuitable for requirements demanding specific unit cost tracking.
- ✓
Specific identification
Why this is correct
Specific identification maps the inventory issue directly to the corresponding inventory receipt record. This ensures that the cost of the item issued matches the cost of the item purchased, providing the highest level of accuracy for high-value inventory items where individual cost tracking is a business requirement.
- ✗
LIFO
Why it's wrong here
LIFO assumes that the items purchased last are sold first, which is primarily used for tax advantages in inflationary environments. This model relies on cost layers rather than tracking the physical cost of specific units, meaning it cannot provide the granular financial accuracy required for specific item identification.
