Worked-example setupScope and assumptions
- Cedar Trail is fictional, and the cost classifications and normal-capacity conclusion are supplied for this exercise.
- The periodic and perpetual figures are separate illustrations and do not extend the accepted cost pool.
- The perpetual difference remains unexplained; no loss entry is authorized.
- Period
- One annual reporting period
- Units
- Inventory units and US dollars
- Rounding
- Whole units and whole US dollars; no rounding required
Cedar Trail incurred $20,000 of supplier price, $1,000 of ordinary inbound freight, and $2,500 of normal assembly cost. It also incurred $600 of emergency freight caused by its scheduling error, $700 of abnormal spoilage, and $900 of sales commissions.
The supplied facts support a $23,500 inventory-cost pool. Supplier price, ordinary inbound freight, and normal assembly bring the goods to their existing condition and location. Expense the emergency freight, abnormal spoilage, and sales commissions. ASC 330-10-30-1 through 30-8 provides those cost and abnormal-item boundaries.
For a separate periodic illustration, beginning inventory is $8,000, net purchases are $20,000, and supported ending inventory is $7,000. Cost of goods sold is $21,000:
Beginning inventory $8,000
Net purchases 20,000
Goods available 28,000
Ending inventory (7,000)
Cost of goods sold $21,000
For a separate perpetual illustration, book records show 310 units and the controlled count shows 304. The measurable difference is 6 units. Do not name it shrinkage or post a loss merely because the subtraction works. First test the count process and item ownership. Then examine transaction cutoff, consignments, returns, transfers, measurement units, repeated records, physical damage, and possible loss.
ASC 330-10-30-8 requires an adequate and consistently applied cost system. Paragraph 30-9 addresses cost-flow assumptions. The paragraphs do not make periodic or perpetual records self-validating.
The arithmetic checks $23,500, $21,000, and 6 units. It does not establish cost eligibility, normal capacity, the ending population, the cause of the difference, or the cost-flow method.
Now complete the independent Northstar close.
