26 C.F.R. § 1.471-4

(a) In general—(1) Market definition. Under ordinary circumstances and for normal goods in an inventory, market means the aggregate of the current bid prices prevailing at the date of the inventory of the basic elements of cost reflected in inventories of goods purchased and on hand, goods in process of manufacture, and finished manufactured goods on hand. The basic elements of cost include direct materials, direct labor, and indirect costs required to be included in inventories by the taxpayer (e.g., under section 263A and its underlying regulations for taxpayers subject to that section). For taxpayers to which section 263A applies, for example, the basic elements of cost must reflect all direct costs and all indirect costs properly allocable to goods on hand at the inventory date at the current bid price of those costs, including but not limited to the cost of purchasing, handling, and storage activities conducted by the taxpayer, both prior to and subsequent to acquisition or production of the goods. The determination of the current bid price of the basic elements of costs reflected in goods on hand at the inventory date must be based on the usual volume of particular cost elements purchased (or incurred) by the taxpayer.

(2) Fixed price contracts. Paragraph (a)(1) of this section does not apply to any goods on hand or in process of manufacture for delivery upon firm sales contracts (i.e., those not legally subject to cancellation by either party) at fixed prices entered into before the date of the inventory, under which the taxpayer is protected against actual loss. Any such goods must be inventoried at cost.

(3) Examples. The valuation principles in paragraph (a)(1) of this section are illustrated by the following examples:

(b) Inactive markets. Where no open market exists or where quotations are nominal, due to inactive market conditions, the taxpayer must use such evidence of a fair market price at the date or dates nearest the inventory as may be available, such as specific purchases or sales by the taxpayer or others in reasonable volume and made in good faith, or compensation paid for cancellation of contracts for purchase commitments. Where the taxpayer in the regular course of business has offered for sale such merchandise at prices lower than the current price as above defined, the inventory may be valued at such prices less direct cost of disposition, and the correctness of such prices will be determined by reference to the actual sales of the taxpayer for a reasonable period before and after the date of the inventory. Prices which vary materially from the actual prices so ascertained will not be accepted as reflecting the market.

(c) Comparison of cost and market. Where the inventory is valued upon the basis of cost or market, whichever is lower, the market value of each article on hand at the inventory date shall be compared with the cost of the article, and the lower of such values shall be taken as the inventory value of the article.

(d) Effective date. This section applies to inventory valuations for taxable years beginning after December 31, 1993. For taxable years beginning before January 1, 1994, taxpayers must take reasonable positions on their federal income tax returns with respect to the application of section 263A, and must have otherwise complied with § 1.471-4 (as contained in the 26 CFR part 1 edition revised April 1, 1993). For purposes of this paragraph (d), a reasonable position as to the application of section 263A is a position consistent with the temporary regulations, revenue rulings, revenue procedures, notices, and announcements concerning section 263A applicable in taxable years beginning before January 1, 1994. (See § 601.601(d)(2)(ii)(b) of this chapter.)
