Physical inventory count under ASC 330: shrinkage and cut-off entries
A year-end physical inventory count turns the perpetual inventory ledger into a number that can be defended. Under US GAAP the count itself is an operational procedure, but every difference it reveals has an accounting consequence: missing units are a loss recognized in cost of goods sold in the period in which they occur, goods counted in the wrong period move revenue, cost of sales and payables across the year-end line, and any shrinkage reserve booked during the year has to be trued up to the counted result.
ASC 330 Inventory does not contain a dedicated "shrinkage" subtopic. The answer comes from three pieces working together: the measurement rules of ASC 330 (inventory carried at cost, written down when cost cannot be recovered, abnormal waste charged to the period), the control-transfer rules that decide who owns goods in transit at the balance sheet date, and the auditing standard that makes the count observable evidence for public companies. IFRS reaches the same economic result through IAS 2 Inventories, which states directly that all losses of inventories are recognized as an expense in the period the loss occurs.
For a December year-end company the practical work is the reconciliation from "book" (perpetual records) to "physical" (counted quantities at cost), adjusted for cut-off items, with the residual recorded as shrinkage. In the worked example below that residual is $15,780 on a $1.28 million inventory, of which $12,000 had already been reserved during the year and $3,780 is the year-end true-up to cost of goods sold.

PHYSICAL INVENTORY COUNTS UNDER ASC 330 AND PCAOB AS 2510.
ASC 330 measures inventory at cost and requires a write-down when cost exceeds what the entity expects to recover. After ASU 2015-11, inventory measured using FIFO or average cost is carried at the lower of cost and net realizable value, while inventory measured using LIFO or the retail inventory method stays under the lower of cost or market model. The FASB text is explicit that when net realizable value falls below cost, the difference is recognized as a loss in earnings in the period in which it occurs. A physical count does not change these measurement rules; it supplies the quantities to which they are applied.
The count matters because quantities are the one input the general ledger cannot verify by itself. Perpetual systems record purchases, transfers and sales, but they do not record theft, breakage, evaporation, mis-picks, unrecorded scrap or data-entry errors. Only a count finds them. For a company with a periodic system the count is even more central, because ending inventory is determined by the count and cost of goods sold is the residual.
For public companies the auditing standard reinforces the timing. PCAOB AS 2510 Auditing Inventories says it is ordinarily necessary for the auditor to be present at the time of the count, which may be taken as of the balance sheet date or as of a single date within a reasonable time before or after it. When well-kept perpetual records are checked periodically against physical counts, AS 2510 allows the auditor's observation to take place during or after the period under audit. When the auditor was not present, tests of the accounting records alone are not sufficient, and some physical counts plus tests of intervening transactions are required.
The practical consequence for controllers is that a count taken on a date other than December 31 is acceptable only when the entity can roll the counted balance forward (or backward) to the balance sheet date through reliable perpetual records. The year-end close under US GAAP depends on that roll-forward being as well controlled as the count itself.
··········
INVENTORY CUT-OFF: GOODS IN TRANSIT, CONSIGNMENT AND UNRECORDED RECEIPTS.
A count records what is physically on the floor. The balance sheet must instead show what the entity owns and controls at the reporting date. The gap between the two is the cut-off adjustment, and it is where most year-end inventory errors start.
Goods in transit from suppliers belong to the buyer once control has passed. Shipping terms are the usual indicator: under FOB shipping point the buyer typically obtains control when the goods leave the supplier, so goods shipped on December 29 and received on January 3 are the buyer's December 31 inventory even though nobody could count them. Under FOB destination the goods remain the supplier's until delivery.
Goods in transit to customers follow the same logic from the seller's side. Under ASC 606 revenue is recognized when control transfers, and shipping terms are one of the indicators of when that happens. If a sale was shipped FOB destination on December 30 and delivered on January 2, the goods were still the seller's inventory at year-end. If the system recorded the sale and relieved inventory on the shipping date, both the revenue and the cost of goods sold must be reversed into the next period.
Consignment stock reverses the physical picture. Goods held in the warehouse on behalf of a consignor are counted by the warehouse team but belong to someone else, so they are removed from the physical total. Goods the company has placed with consignees are its own inventory even though they sit in another company's premises.
Unrecorded receipts are the fourth common item. Goods that arrived on December 31 and were counted, but were not entered in the perpetual system until the supplier invoice was processed in January, make the physical count higher than book. The correction is an entry to inventory and to a goods-received-not-invoiced accrual, with no effect on cost of goods sold. Earlier coverage on inventory errors and their effects shows how an uncorrected cut-off error reverses through the following year's gross margin.

HOW INVENTORY SHRINKAGE IS RECORDED UNDER US GAAP.
Shrinkage is the residual difference between the cut-off-adjusted book balance and the cut-off-adjusted physical balance, both valued at cost. Because the missing units no longer exist, there is no asset to carry forward, and the loss is recognized in the period it occurs. Most companies present it within cost of goods sold, since normal shrinkage is a recurring cost of holding and selling inventory.
ASC 330 adds a related rule for production. The guidance that came from FASB Statement No. 151 requires abnormal amounts of idle facility expense, freight, handling costs and wasted material (spoilage) to be recognized as current-period charges rather than capitalized into inventory. Normal production scrap can remain in the cost of good units; abnormal spoilage cannot. A manufacturer that discovers at the count that a batch was scrapped but never recorded must decide whether the loss was normal or abnormal, which affects whether it flows through standard cost variances or is charged directly to the period.
Many retailers and distributors do not wait for the annual count to record shrinkage. They accrue a shrinkage reserve each month at an estimated rate (for example a percentage of cost of sales based on prior counts) and true it up when a count is completed. The reserve is a contra-inventory account, and the true-up goes to cost of goods sold. If the estimated rate was too high, the true-up reduces cost of goods sold; if it was too low, it increases it. An estimate based on historical shrink is consistent with US GAAP so long as it is updated for the actual count result before the annual financial statements are issued.
Shrinkage is a quantity loss. It differs from a write-down for obsolete, damaged or slow-moving goods that still exist, which is a valuation loss under the lower of cost and net realizable value test. The two often surface in the same count, since counters also tag damaged and aged items, but they should be recorded and analyzed separately. The site's analysis of how inventory write-downs affect profitability and financial ratios covers the valuation side.

INVENTORY COUNT DIFFERENCES UNDER IAS 2.
IAS 2 Inventories measures inventories at the lower of cost and net realisable value (paragraph 9) and states in paragraph 34 that the amount of any write-down to net realisable value and all losses of inventories are recognized as an expense in the period the write-down or loss occurs. Shrinkage found at a count is therefore expensed immediately, with the same practical result as under US GAAP.
IAS 2 paragraph 16 lists abnormal amounts of wasted materials, labour or other production costs among the costs excluded from inventory and expensed as incurred, which mirrors the ASC 330 treatment of abnormal spoilage. Paragraph 21 allows the standard cost method or the retail method for convenience if the results approximate cost, which is relevant because count differences in retail environments are often valued at retail and converted to cost with a cost-to-retail ratio.
The main structural difference is the cost formula. IAS 2 paragraph 25 allows only FIFO or weighted average cost for interchangeable items, while US GAAP still permits LIFO. For a LIFO company, shrinkage reduces LIFO quantities, and a large count loss can contribute to the liquidation of older, lower-cost layers. An IFRS reporter never faces that interaction. The broader measurement comparison is covered in how inventory is measured and reported under IAS 2 and ASC 330.

WORKED EXAMPLE: YEAR-END INVENTORY COUNT RECONCILIATION AND JOURNAL ENTRIES.
The following example is illustrative. A US distributor with a December 31 year-end uses a perpetual FIFO system and accrues a shrinkage reserve monthly at an estimated rate. Before the count, the reserve balance is $12,000. The perpetual records show inventory at cost of $1,248,600. The physical count on December 31, priced at FIFO cost, totals $1,246,520. The cut-off review finds four items.
First, goods costing $18,400 were shipped by a supplier FOB shipping point on December 29 and arrived on January 3; the invoice was entered on January 4, so they are neither in book nor in the count. Second, a customer order shipped FOB destination on December 30 and delivered on January 2 was recorded as a $15,000 sale with $9,800 cost on December 30. Third, the warehouse holds consigned goods of $6,200 belonging to a supplier, and they were counted. Fourth, goods costing $7,500 were received and counted on December 31 but entered in the perpetual system only in January.
........
Reconciliation line | Book (perpetual) | Physical count |
Balance before adjustments | 1,248,600 | 1,246,520 |
Inbound in transit, FOB shipping point | 18,400 | 18,400 |
Outbound in transit, FOB destination | 9,800 | 9,800 |
Consigned goods held for supplier | 0 | (6,200) |
Received and counted, not yet recorded | 7,500 | 0 |
Adjusted balance | 1,284,300 | 1,268,520 |
Shrinkage (book less physical) | 15,780 |
........
The shrinkage of $15,780 is 1.23% of the adjusted book balance. The reserve accrued during the year covered $12,000 of it, so the year-end true-up adds $3,780 to cost of goods sold. After the entries below, the inventory account equals the adjusted physical balance of $1,268,520 and the shrinkage reserve is zero.
........
Entry | Account | Debit | Credit |
1. Inbound goods in transit | Inventory | 18,400 | |
Accounts payable | 18,400 | ||
2. Reverse premature sale | Sales revenue | 15,000 | |
Accounts receivable | 15,000 | ||
2. Reinstate inventory | Inventory | 9,800 | |
Cost of goods sold | 9,800 | ||
3. Unrecorded receipt | Inventory | 7,500 | |
Accrued liabilities (goods received not invoiced) | 7,500 | ||
4. Shrinkage true-up | Inventory shrinkage reserve | 12,000 | |
Cost of goods sold | 3,780 | ||
Inventory | 15,780 | ||
Total | 66,480 | 66,480 |
........
The consigned goods need no entry, because they were never in the books; they are only removed from the count sheet. The revenue reversal in entry 2 is recognized again in January when the customer obtains control. Total shrinkage cost for the year in cost of goods sold is $15,780: $12,000 through the monthly reserve accruals and $3,780 through the true-up. Under IFRS the entries would be the same, since the cut-off analysis and the expense recognition of losses follow the same logic.

COUNTS BEFORE YEAR-END: ROLL-FORWARD TO THE BALANCE SHEET DATE.
Many companies count in November to free up the December close. The counted balance is then rolled forward through December activity recorded in the perpetual system, and shrinkage for December is estimated at the reserve rate. In the illustrative case below, a separate company counted on November 30 and accrues December shrinkage at 1% of cost of sales.
........
Roll-forward line | Amount |
Adjusted physical count, November 30 | 1,190,000 |
December purchases received | 412,300 |
December cost of sales | (356,800) |
December shrinkage accrual at 1% of cost of sales | (3,568) |
Expected inventory, December 31 | 1,241,932 |
........
The roll-forward is only as good as the December transaction data. Auditors following AS 2510 test the intervening transactions, so receiving logs, shipping documents and the December cut-off need the same attention they would get with a December 31 count. A large unexplained difference at the November count is also a reason to reconsider whether the reserve rate used for December is still realistic.
··········
PRESENTATION AND DISCLOSURE OF INVENTORY SHRINKAGE.
Normal shrinkage is presented within cost of goods sold, and the shrinkage reserve is netted against inventory on the balance sheet. ASC 330 requires disclosure of the basis on which inventories are stated, including the cost method, and SEC registrants typically describe their shrinkage estimation policy in the inventory accounting policy note when the reserve is significant. Retailers often discuss shrink as a driver of gross margin in management's discussion and analysis.
A shrinkage loss that is unusual in size, such as a theft or a warehouse incident, may call for separate disclosure, and an insured loss raises a separate question about when the insurance recovery can be recognized. Under IFRS, IAS 2 paragraph 36 requires disclosure of the accounting policies adopted in measuring inventories, including the cost formula used.
··········
COMMON INVENTORY COUNT ERRORS AND JUDGMENT AREAS.
The most frequent error is treating every book-to-physical difference as shrinkage without first resolving cut-off. A goods-in-transit item recorded as shrinkage overstates cost of goods sold in the current year and understates it in the next, while a misclassified consignment item inflates inventory and gross margin.
The second is valuing the count at the wrong cost. Count quantities must be priced with the same cost formula as the ledger (FIFO, average or LIFO) and with standard costs that have been updated for capitalized variances. A count priced at an outdated standard produces an artificial difference that is a costing error, not a physical loss.
Judgment is needed in four places: whether a loss is normal shrinkage or an abnormal event to be separately analyzed, whether a manufacturing scrap loss is normal or abnormal spoilage, whether the estimated reserve rate reflects current conditions, and whether a count away from year-end can be rolled forward reliably. Control weaknesses discovered at the count, such as receipts not recorded promptly, should also feed into the assessment of internal control over financial reporting.

PHYSICAL INVENTORY AND SHRINKAGE UNDER ASC 330: FIRM RULES AND JUDGMENT CALLS.
The rules are firm on three points. Shrinkage is a loss of the period in which it occurs, recognized in earnings and normally presented in cost of goods sold, under both ASC 330 and IAS 2. Abnormal spoilage and waste are charged to the period rather than capitalized under both frameworks. Goods belong in inventory when the entity controls them at the reporting date, regardless of where they physically sit during the count.
The judgment calls are in the estimates and the evidence: the shrinkage rate accrued between counts, the split between normal and abnormal losses, the reliability of a roll-forward from a count taken before year-end, and the cut-off review of goods in transit and consignment stock. A reconciliation that clears cut-off first, prices the count at the ledger cost formula and only then books the residual as shrinkage produces an inventory balance and a cost of goods sold figure that hold up in the audit.
