26 C.F.R. §§ 1.985-1–1.985-6

In general. For taxable years beginning after August 24, 1994, except as otherwise provided in paragraph (b)(2)(ii)(B) of this section, any QBU that otherwise would be required to use a hyperinflationary currency as its functional currency must use the dollar as its functional currency and compute income or loss or earnings and profits under the rules of § 1.985-3.

Exceptions— (1) Certain QBU branches. The functional currency of a QBU that otherwise would be required to use a hyperinflationary currency as its functional currency and that is a branch of a foreign corporation having a non-dollar functional currency that is not hyperinflationary shall be the functional currency of the foreign corporation. Such QBU's income or loss or earnings and profits shall be determined under § 1.985-3 by substituting the functional currency of the foreign corporation for the dollar.

Change in functional currency— (1) In general. If a QBU is required to change its functional currency to the dollar under paragraph (b)(2)(ii)(A) of this section, or chooses or is required to change its functional currency to the dollar for any open taxable year (and all subsequent taxable years) under § 1.985-3(a)(2)(ii), the change is considered to be made with the consent of the Commissioner for purposes of § 1.985-4. A QBU changing functional currency must make adjustments described in § 1.985-7 if the year of change (as defined in § 1.481-1(a)(1)) begins after 1987, or the adjustments described in § 1.985-6 if the year of change begins in 1987. No adjustments under section 481 are required solely because of a change in functional currency described in this paragraph (b)(2)(ii)(C).

Hyperinflationary currency. For purposes of sections 985 through 989, the term hyperinflationary currency means the currency of a country in which there is cumulative inflation during the base period of at least 100 percent as determined by reference to the consumer price index of the country listed in the monthly issues of the “International Financial Statistics” or a successor publication of the International Monetary Fund. If a country's currency is not listed in the monthly issues of “International Financial Statistics,” a QBU may use any other reasonable method consistently applied for determining the country's consumer price index. Base period means, with respect to any taxable year, the thirty-six calendar months immediately preceding the first day of the current calendar year. For this purpose, the cumulative inflation rate for the base period is based on compounded inflation rates. Thus, if for 1991, 1992, and 1993, a country's annual inflation rates are 29 percent, 25 percent, and 30 percent, respectively, the cumulative inflation rate for the three-year base period is 110 percent [((1.29 × 1.25 × 1.3)−1.0 × 1.10) × 100 = 110%] and the currency of the country for the QBU's 1994 year is considered hyperinflationary. In making the determination whether a currency is hyperinflationary, the determination for purposes of United States generally accepted accounting principles may be used for income tax purposes provided the determination is based on criteria that is substantially similar to the rules previously set forth in this paragraph (b)(2)(ii)(D), the method of determination is applied consistently from year to year, and the same method is applied to all related persons as defined in § 1.985-3(e)(2)(vi).

Change in functional currency when currency ceases to be hyperinflationary— (1) In general. A QBU that has been required to use the dollar as its functional currency under paragraph (b)(2) of this section, or has elected to use the dollar as its functional currency under paragraph (b)(2)(ii)(B)(2) of this section or § 1.985-2, must change its functional currency as of the first day of the first taxable year that follows three consecutive taxable years in which the currency of its economic environment, determined under paragraph (c)(2) of this section, is not a hyperinflationary currency. The functional currency of the QBU for such year shall be determined in accordance with paragraph (c) of this section. For purposes of § 1.985-4, the change is considered to be made with the consent of the Commissioner. See § 1.985-5 for adjustments that are required upon a change in functional currency.

In general. Amounts representing items included in the closing inventory balance shall be translated at the exchange rate for the translation period in which the cost of such items was incurred. However, if amounts representing items included in the closing inventory balance are either valued at market or written down to market value, they shall be translated at the exchange rate existing on the last day of the taxable year. For purposes of determining lower of cost or market, items of inventory included in the closing inventory balance shall be translated into dollars at the exchange rate for the translation period in which the cost of such items was incurred and compared with market as determined in the QBU's hyperinflationary currency translated into dollars at the exchange rate existing on the last day of the taxable year.

Determination of translation period. The method used to determine the translation period of amounts representing items of closing inventory for purposes of paragraph (c)(3)(iii)(A) of this section may be based upon reasonable approximations and averages, including rates of turnover, provided that the method is used consistently from year to year.

QBUs that are branches of United States persons. For the first year in which this election is effective, in the case of a QBU branch of a United States person, a statement shall be attached to the United States person's timely filed Federal income tax return (taking extensions into account). The statement shall identify the QBU (or QBUs) for which the election is being made by describing its business and its country of residence, state the adjusted basis of the assets of the QBU (and any related same-country QBUs) to which the election applies, and include a statement that the election is being made pursuant to § 1.985-3(e)(2).

Other QBUs. In the case of a QBU other than one described in paragraph (e)(2)(iii)(A) of this section, an election must be made in the manner prescribed in § 1.964-1. The statement filed with the Internal Revenue Service as required under § 1.964-1 must include the information required under paragraph (e)(2)(iii)(A) of this section.

General rule. The taxpayer shall determine the dollar amount of DASTM gain or loss attributable to assets in each group identified in paragraph (e)(3)(iii) of this section (Step 3) as follows:

Weighting to prevent distortion. If averaging the adjusted basis of assets in a group at the beginning and end of a balance sheet period results in an allocation of DASTM gain or loss that does not clearly reflect income, as might be the case in the event of a purchase or disposition of an asset that is not in the normal course of business, the taxpayer must use a weighting method that reflects the time the assets are held by the QBU during the translation period.

Example. The provisions of this paragraph (e)(3)(iv) are illustrated by the following example:

General rule. The taxpayer shall determine the dollar amount of DASTM gain or loss attributable to liabilities identified in paragraph (e)(3)(ii) of this section (Step 2), and described in paragraph (e)(3)(vi)(B) of this section as follows:

Separate calculation. The calculation shall be made separately for interest-bearing liabilities described in paragraph (e)(3)(vii) of this section (Step 7) and for each of the classes of non-interest-bearing liabilities described in paragraph (e)(3)(viii) of this section (Step 8).

Weighting to prevent distortion. Where a distortion would result from averaging the amount of liabilities at the beginning and end of a balance sheet period, as might be the case where a taxpayer incurs or retires a substantial liability, the taxpayer must use a different method that more clearly reflects the average amount of liabilities weighted to reflect the time the liability was outstanding during the balance sheet period.

In general. The taxpayer shall apply the amount of DASTM gain on interest-bearing liabilities computed under paragraph (e)(3)(vi) of this section (Step 6) to reduce interest expense generated by such liabilities (e.g., prior to the application of § 1.861-9T or its successor regulation). To the extent DASTM gain on such liabilities exceeds interest expense, it shall be sourced or otherwise classified in the same manner that interest expense is allocated and apportioned under § 1.861-9T or its successor regulation. The amount of DASTM loss on interest-bearing liabilities computed under paragraph (e)(3)(vi) of this section (Step 6) shall be allocated and apportioned in the same manner that interest expense is allocated and apportioned under § 1.861-9T or its successor regulation (without regard to the exceptions to fungibility in § 1.861-10T or its successor regulation). For purposes of this section, an interest-bearing liability is a liability that requires payment of periodic interest (whether fixed or variable), has original issue discount, or would have interest imputed under subtitle A.

Allocation of DASTM gain or loss from interest-bearing liabilities that generate related person interest expense. DASTM gain or loss from interest-bearing liabilities that generate related person interest expense (as provided in section 954(b)(5)) shall be allocated for purposes of subtitle A (including sections 904 and 952) in the same manner that the related person interest expense of that debt is required to be allocated under the rules of section 954(b)(5) and § 1.904-5(c)(2).

Modified gross income method. In applying the modified gross income method described in § 1.861-9T(j) or its successor regulation, gross income shall be adjusted for any DASTM gain or loss from assets as provided in paragraph (e)(3)(v) of this section (Step 5) and any DASTM gain or loss with respect to short-term, non-interest-bearing trade payables as provided in paragraph (e)(3)(viii)(A) of this section.

Short-term, non-interest-bearing trade payables. The taxpayer shall allocate DASTM gain or loss on short-term non-interest-bearing trade payables for purposes of subtitle A (including sections 904 and 952) to the same category or type of gross income as the cost or expense to which the trade payable relates. For this purpose, a short-term, non-interest-bearing trade payable is a non-interest-bearing liability with a term of 183 days or less that is incurred to purchase property or services to be used by the obligor in an active trade or business.

Excise tax payables. The taxpayer shall allocate DASTM gain or loss on excise tax payables for purposes of subtitle A (including sections 904 and 952) to the same category or type of gross income as would be derived from the activity to which the excise tax relates.

Other non-interest-bearing liabilities— (1) In general. Except as provided in paragraphs (e)(3)(viii)(A), (e)(3)(viii)(B), and (e)(3)(viii)(C)(2) of this section, DASTM gain or loss on non-interest-bearing liabilities shall be allocated under paragraph (e)(3)(ix) of this section (Step 9).
