§ 1.987-3. Determination of section 987 taxable income or loss of an owner of a section 987 QBU.

¶(A) In general. A taxpayer may elect to apply the section 988 mark-to-market method of accounting described in this paragraph (b)(4)(ii) with respect to all section 988 transactions that are properly attributable to a section 987 QBU and that are not otherwise accounted for under a mark-to-market method of accounting under section 475 or section 1256 (other than a section 988 transaction described in paragraph (b)(4)(ii)(B) of this section). Under the section 988 mark-to-market method of accounting, the timing of section 988 gain or loss on section 988 transactions described in the preceding sentence is determined under the principles of section 1256. Only section 988 gain or loss is taken into account under the foreign currency mark-to-market method of accounting. Appropriate adjustments must be made to prevent the section 988 gain or loss from being taken into account again after it is recognized under this paragraph (b)(4)(ii). A section 988 transaction subject to the foreign currency mark-to-market method of accounting is not subject to the netting rule of section 988(b) and § 1.988-2(b)(8) (under which exchange gain or loss is limited to overall gain or loss realized in a transaction) in taxable years before the taxable year in which section 988 gain or loss would be recognized with respect to the section 988 transaction but for this election.

¶(B) Built-in loss transactions contributed to a section 987 QBU. Paragraph (b)(4)(ii)(A) of this section does not apply to a section 988 transaction if—

¶(A) General rule—simplified inventory method. Except as otherwise provided in paragraph (c)(2)(iv)(B) of this section, cost of goods sold (COGS) for a taxable year is translated into the functional currency of the owner at the yearly average exchange rate for the taxable year in which the sale of inventory occurs (or the COGS is otherwise taken into account in computing taxable income) and adjusted as provided in paragraph (c)(3) of this section.

¶(B) Election to use the historic inventory method. In lieu of using the simplified inventory method described in paragraph (c)(2)(iv)(A) of this section, the owner of a section 987 QBU may elect under this paragraph (c)(2)(iv)(B) to translate inventoriable costs (including current-year inventoriable costs and costs that were capitalized into inventory in prior years) that are included in COGS at the historic rate for each such cost.

¶(A) In general. The translated COGS amount computed under paragraph (c)(2)(iv)(A) of this section is increased or decreased (as appropriate) by the amount described in paragraph (c)(3)(ii)(B) of this section. The adjustment is included as an adjustment to translated COGS computed under paragraph (c)(2)(iv)(A) of this section in full in the year to which the adjustment relates and is not allocated between COGS and ending inventory.

¶(B) Amount of adjustment. With respect to each cost recovery deduction attributable to a historic asset that is included in inventoriable costs for a taxable year, the adjustment is equal to—

¶(A) In general. In the case of non-LIFO inventory, the translated COGS amount computed under paragraph (c)(2)(iv)(A) of this section is increased or decreased (as appropriate) by the amount described in paragraph (c)(3)(iii)(B) of this section.

¶(B) Amount of adjustment. The adjustment is equal to—

¶(C) Exchange rate—

¶(A) In general. In the case of inventory with respect to which a section 987 QBU uses the LIFO inventory method, the translated COGS amount computed under paragraph (c)(2)(iv)(A) of this section is increased or decreased (as appropriate) by the amount described in paragraph (c)(3)(iv)(B) of this section.

¶(B) Amount of adjustment. With respect to each LIFO layer liquidated in whole or in part during the taxable year, the adjustment is equal to:

¶(A) Gross sales. Business A's gross sales are translated under paragraph (c)(1) of this section at the yearly average exchange rate for the year of the sale. Business A's dollar gross sales will be computed as follows:

¶(B) Translated basis of inventory. The purchase price for each inventory unit was €1.50. Under § 1.987-1(c)(3)(i) and paragraph (c)(2)(iv)(B) of this section, the basis of each item of inventory is translated into dollars at the yearly average exchange rate for the year the inventory was acquired.

¶(C) COGS. Because Business A uses a FIFO method for inventory, Business A is considered to have sold in year 2 the 100 units of opening inventory purchased in year 1 ($153.00), the 300 units purchased in January year 2 ($472.50), the 300 units purchased in April year 2 ($472.50), the 300 units purchased in July year 2 ($472.50), and 200 of the 300 units purchased in November year 2 ($315.00). Accordingly, Business A's translated dollar COGS for year 2 is $1,885.50. Business A's opening inventory for year 3 is 100 units of inventory with a translated dollar basis of $157.50.

¶(D) Gross sales income. Accordingly, for purposes of section 987, Business A has gross income in dollars of $1,894.50 ($3,780.00−$1,885.50) from the sale of inventory in year 2.

¶(A) Gross sales. Business A's dollar gross sales will be computed as described in paragraph (e)(3)(ii)(A) of this section (Example 3). Therefore, Business A has gross sales of $3,780.

¶(B) COGS. Business A sold 1,200 units of inventory in year 2, and the purchase price for each unit was €1.50. The total purchase price for the inventory sold in year 2 was €1,800. Under the simplified inventory method provided in paragraph (c)(2)(iv)(A) of this section, COGS for a taxable year is translated into the functional currency of the owner at the yearly average exchange rate for the taxable year in which the sale of inventory occurs. Therefore, before making the adjustments required under paragraph (c)(3) of this section, Business A's dollar COGS for year 2 is equal to $1,890 (the purchase price for the inventory sold in year 2 (€1,800), translated at the yearly average exchange rate of €1 = $1.05).

¶(C) Adjustments required. Because the simplified inventory method applies, Business A's COGS must be adjusted under paragraph (c)(3) of this section. No adjustment is required under paragraph (c)(3)(ii) of this section because no cost recovery deduction attributable to a historic asset is included in inventoriable costs for year 2. However, an adjustment for beginning inventory is required under paragraph (c)(3)(iii)(A) of this section because Business A uses a FIFO method of accounting for inventory.

¶(D) Adjustment for beginning inventory. The adjustment required under paragraph (c)(3)(iii)(A) of this section is equal to: the ending non-LIFO inventory included on Business A's closing balance sheet for the preceding taxable year (€150), translated at the yearly average exchange rate for year 1 (€1 = $1.02), which is $153; less the ending non-LIFO inventory included on Business A's closing balance sheet for the preceding taxable year (€150), translated at the yearly average exchange rate for year 2 (€1 = $1.05), which is $157.50. Therefore, there is a negative adjustment to COGS of $4.50. Business A's COGS for year 2 is reduced from $1,890 to $1,885.50.

¶(E) Gross sales income. Accordingly, for purposes of section 987, Business A has gross income in dollars of $1,894.50 ($3,780.00−$1,885.50) from the sale of inventory in year 2.

¶(A) Under paragraph (b)(2) of this section, the $100 earned by Business A is translated into €100 at the spot rate on January 1, 2021, as defined in § 1.987-1(c)(1) without the use of a spot rate convention. In determining U.S. Corp's taxable income, the €100 of services income is translated into $150 at the yearly average exchange rate for 2021, as provided in paragraph (c)(1) of this section.

¶(B) Under paragraph (b)(4)(i) of this section, section 988 gain or loss for Business A's section 988 transactions is determined in, and by reference to, the euro, the functional currency of Business A. Accordingly, section 988 gain or loss must be determined on Business A's holding of the $100 demand deposit in, and by reference to, the euro. Under § 1.988-2(a)(2), Business A is treated as having an amount realized of €50 when the $100 is marked to market at the end of 2021 under paragraph (b)(4)(ii) of this section. Marking the dollars to market gives rise to a section 988 loss of €50 (€50 amount realized, less Business A's €100 basis in the $100). In determining U.S. Corp's taxable income, that €50 loss is translated into a $75 loss at the yearly average exchange rate for 2021, as provided in paragraph (c)(1) of this section.
