Inventory

ASC 330 establishes that inventory is initially measured at cost — all direct and indirect expenditures incurred to bring an article to its existing condition and location — with fixed overhead allocated on normal capacity and abnormal freight, handling, spoilage, and idle-capacity overhead expensed as period charges (330-10-30-1 through 30-8). Cost may be assigned using FIFO, average cost, LIFO, standard cost, or the retail inventory method, applied consistently to most clearly reflect periodic income; subsequent measurement is bifurcated, with LIFO and retail-method inventory subject to lower of cost or market (replacement cost capped at NRV and floored at NRV less normal profit) and all other inventory measured at lower of cost and net realizable value, a write-down creating a new cost basis that cannot be reversed (330-10-35-1B through 35-14). Industry subtopics tailor these rules: agriculture (330-905) accumulates growing-crop costs to harvest and permits NRV/market valuation for readily marketable products; mining (330-930) treats production-phase stripping costs as variable production costs of the ore extracted; airlines (330-908) carry expendable parts at cost with an obsolescence allowance; software (330-985), films (330-926), time-shares (330-978, relative sales value method), oil and gas (330-932), government contractors (330-912), and retail land (330-976) add narrow recognition, measurement, or disclosure rules, while construction contractor guidance (330-910) is fully superseded. The unifying idea is that inventory is carried at cost until cost exceeds the value recoverable through sale, at which point the loss is recognized immediately.
Subtopics
- 10Overall89 ¶
ASC 330-10 governs the accounting for inventory: inventory is initially measured at cost (all expenditures and charges, direct and indirect, incurred to bring an article to its existing condition and location), with fixed production overhead allocated based on normal capacity and unallocated overhead, abnormal freight, handling, and spoilage expensed as incurred. Cost may be assigned using FIFO, average cost, LIFO, standard cost, or the retail inventory method, chosen to most clearly reflect periodic income and applied consistently. Subsequent measurement is bifurcated: inventory measured under LIFO or the retail inventory method uses lower of cost or market, while all other inventory (FIFO, average cost) uses lower of cost and net realizable value.
- 905Agriculture32 ¶
ASC 330-905 applies Inventory guidance to the agricultural industry, covering producers (growing crops, developing animals, harvested crops, livestock held for sale, secondary products), pooling cooperatives, and cooperative patrons. Direct and indirect costs of growing crops are accumulated until harvest, with pre-planting costs deferred and post-harvest cultural costs estimated and accrued to the harvested crop. Harvested crops and animals held for sale may be carried at net realizable value if they have a reliable, readily determinable market price, insignificant and predictable disposal costs, and immediate availability for delivery; otherwise Subtopic 330-10 measurement applies.
- 908Airlines9 ¶
ASC 330-908 governs inventory accounting for airlines, where "inventory" consists of expendable spare parts, materials, and supplies held for internal consumption rather than sale. Expendable parts are recorded at cost in a current asset account akin to a prepaid expense, carry an allowance for obsolescence tied to the lives of the related fleets, and are charged to expense as used.
- 910Contractors—Construction5 ¶
ASC 330-910 was the inventory guidance specific to construction contractors, addressing how contractors accounted for inventoried costs (e.g., uninstalled materials and precontract costs) under Topic 330. All of its substantive paragraphs — Sections 05 (Overview and Background), 15 (Scope), 25 (Recognition), and 40 (Derecognition) — were superseded by Maintenance Update No. 2019-01, so the subtopic contains no operative guidance. Contractors now look to the general inventory guidance in Topic 330 and to the revenue and contract cost guidance in Topics 606 and 340-40.
- 912Contractors—Federal Government7 ¶
This Subtopic gives government contractors narrow guidance on inventory affected by contracts terminated for the convenience of the government, plus disclosure of the accounting policy for costs included in contract inventory. If inventory whose costs are in the termination claim is later reacquired by the contractor, the reacquisition value is recorded as a purchase; in "no-cost settlements," where the contractor waives its claim, no sale transaction arises and retained inventory is accounted for under ordinary inventory methods rather than as a purchase.
- 926Entertainment—Films3 ¶
This subtopic applies inventory accounting to film production and distribution entities that hold physical products for sale, such as videocassettes and digital video discs. Its core rule is that at each balance sheet date the entity must evaluate these product inventories for net realizable value and obsolescence exposure and record appropriate adjustments (330-926-35-1). Scope follows the Entertainment—Films Overall Subtopic scope in Section 926-10-15.
- 930Extractive Activities—Mining4 ¶
This subtopic governs how mining entities account for stripping costs — the costs of removing overburden and waste materials to access ore — incurred during the production phase of a mine. The core rule is that post-production-phase stripping costs are variable production costs that must be capitalized into the cost of the inventory (ore) extracted in the same period the stripping costs are incurred. Stripping costs incurred before the production phase (i.e., during development) are outside the scope of this subtopic.
- 932Extractive Activities—Oil and Gas5 ¶
This Subtopic governs inventory accounting for entities in the oil and gas (extractive activities) industry, borrowing the scope of ASC 932-10-15. Its core rules are prohibitions: energy trading contracts that are not derivatives under Topic 815 may not be subsequently measured at fair value through earnings, and physical inventories may not be measured at fair value unless another Topic permits it. Exchanges (buying and selling inventory with the same counterparty) are directed to ASC 845-10-15-5 through 15-9.
- 976Real Estate—Retail Land3 ¶
This Subtopic sets the inventory-related disclosure requirements for entities engaged in retail land sales operations, focusing on future expenditures for land improvements. Entities must disclose the estimated total costs and timing of improvement expenditures for major selling areas for each of the five years after the balance sheet date, plus any recorded obligations for improvements (330-976-50-1).
- 978Real Estate—Time-Sharing Activities16 ¶
ASC 330-978 governs how time-share sellers measure time-sharing inventory (intervals) and cost of sales. Sellers must use the relative sales value method, applied phase by phase, with common costs (including amenities) allocated among benefited phases, and must recalculate total estimated time-sharing revenue and total costs at least quarterly. Changes in estimate are recorded as current-period adjustments, and rental/other activity during the holding period is treated as incidental operations that reduce the pool of inventory costs.
- 985Software4 ¶
This subtopic governs how a software vendor accounts for the costs of producing physical copies of software to be sold, leased, or otherwise marketed. Costs of duplicating the software, documentation, and training materials from the product masters and of physically packaging the product for distribution are capitalized as inventory on a unit-specific basis (330-985-25-1). Those capitalized costs are charged to cost of sales when revenue from the sale of the related units is recognized (330-985-40-1).
