Sec. 1.985-1  Functional currency.

    (a) Applicability and effective date--(1) Purpose and scope. These 
regulations provide guidance with respect to defining the functional 
currency of a taxpayer and each qualified business unit (QBU), as 
defined in section 989(a). Generally, a taxpayer and each QBU must make 
all determinations under subtitle A of the Code (relating to income 
taxes) in its respective functional currency. This section sets forth 
rules for determining when the functional currency is the United States 
dollar (dollar) or a currency other than the dollar. Section 1.985-2 
provides an election to use the dollar as the functional currency for 
certain QBUs that absent the election would have a functional currency 
that is a hyperinflationary currency, and explains the effect of making 
the election. Section 1.985-3 sets forth the dollar approximate separate 
transactions method that certain QBUs must use to compute their income 
or loss or earnings and profits. Section 1.985-4 provides that the 
adoption of a functional currency is a method of accounting and sets 
forth conditions for a change in functional currency. Section 1.985-5 
provides adjustments that are required to be made upon a change in 
functional currency. Finally, Sec. 1.985-6 provides transition rules 
for a QBU that uses the dollar approximate separate transactions method 
for its first taxable year beginning after December 31, 1986.
    (2) Effective date. These regulations apply to taxable years 
beginning after December 31, 1986. However, any taxpayer desiring to 
apply temporary Income Tax Regulations Sec. 1.985-0T through Sec. 
1.985-4T in lieu of these regulations to all taxable years beginning 
after December 31, 1986, and on or before October 20, 1989 may (on a 
consistent basis) so choose. For the text of the temporary regulations, 
see 53 FR 20308 (1988).
    (b) Dollar functional currency--(1) In general. The dollar shall be 
the functional currency of a taxpayer or QBU described in paragraph 
(b)(1)(i) through (v) of this section regardless of the currency used in 
keeping its books and records (as defined in Sec. 1.989(a)-1(d)). The 
dollar shall be the functional currency of--
    (i) A taxpayer that is not a QBU (e.g., an individual);
    (ii) A QBU that conducts its activities primarily in dollars. A QBU 
conducts its activities primarily in dollars if the currency of the 
economic environment in which the QBU conducts its activities is 
primarily the dollar. The facts and circumstances test set forth in 
paragraph (c)(2) of this section shall apply in making this 
determination;
    (iii) Except as otherwise provided by ruling or administrative 
pronouncement, a QBU that has the United States, or any possession or 
territory of the United States where the dollar is the standard 
currency, as its residence (as defined in section 988(a)(3)(B));

[[Page 541]]

    (iv) A QBU that does not keep books and records in the currency of 
any economic environment in which a significant part of its activities 
is conducted. Whether a QBU keeps such books and records is determined 
in accordance with paragraph (c)(3) of this section; or
    (v) A QBU that produces income or loss that is, or is treated as, 
effectively connected with the conduct of a trade or business within the 
United States.
    (2) QBUs operating in a hyperinflationary environment--(i) Taxable 
years beginning on or before August 24, 1994. For taxable years 
beginning on or before August 24, 1994, see Sec. 1.985-2 with respect 
to a QBU that elects to use, or is otherwise required to use, the dollar 
as its functional currency.
    (ii) Taxable years beginning after August 24, 1994--(A) 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 Sec. 
1.985-3.
    (B) 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 Sec. 1.985-3 by substituting the functional currency 
of the foreign corporation for the dollar.
    (2) Corporation that is not a controlled foreign corporation. A 
foreign corporation (or its QBU branch) operating in a hyperinflationary 
environment is not required to use the dollar as its functional currency 
pursuant to paragraph (b)(2)(ii)(A) of this section if that foreign 
corporation is not a controlled foreign corporation as defined in 
section 957 or 953(c)(1)(B). However, a noncontrolled section 902 
corporation, as defined in section 904(d)(2)(E), may elect to use the 
dollar (or, if appropriate, the currency specified in paragraph 
(b)(2)(ii)(B)(1) of this section) as its (or its QBU branch's) 
functional currency under the procedures set forth in Sec. 1.985-
2(c)(3).
    (C) 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 Sec. 1.985-3(a)(2)(ii), the change is 
considered to be made with the consent of the Commissioner for purposes 
of Sec. 1.985-4. A QBU changing functional currency must make 
adjustments described in Sec. 1.985-7 if the year of change (as defined 
in Sec. 1.481-1(a)(1)) begins after 1987, or the adjustments described 
in Sec. 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).
    (2) Effective date. This paragraph (b)(2)(ii)(C) applies to taxable 
years beginning after April 6, 1998. However, a taxpayer may choose to 
apply this paragraph (b)(2)(ii)(C) to all open years after December 31, 
1986, provided each person, and each QBU branch of a person, that is 
related (within the meaning of Sec. 1.985-2(d)(3)) also applies to this 
paragraph (b)(2)(ii)(C).
    (D) 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,

[[Page 542]]

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 x 1.25 x 1.3)-1.0 x 
1.10)x100=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 Sec. 1.985-3(e)(2)(vi).
    (E) 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 Sec. 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 Sec. 1.985-4, the change is 
considered to be made with the consent of the Commissioner. See Sec. 
1.985-5 for adjustments that are required upon a change in functional 
currency.
    (2) Effective Date. This paragraph (b)(2)(ii)(E) of this section 
applies to taxable years beginning after April 6, 1998.
    (c) Functional currency of a QBU that is not required to use the 
dollar--(1) General rule. The functional currency of a QBU that is not 
required to use the dollar under paragraph (b) of this section shall be 
the currency of the economic environment in which a significant part of 
the QBU's activities is conducted, if the QBU keeps, or is presumed 
under paragraph (c)(3) of this section to keep, its books and records in 
such currency.
    (2) Economic environment. For purposes of section 985 and the 
regulations thereunder, the economic environment in which a significant 
part of a QBU's activities is conducted shall be determined by taking 
into account all the facts and circumstances.
    (i) Facts and circumstances. The facts and circumstances that are 
considered in determining the economic environment in which a 
significant part of a QBU's activities is conducted include, but are not 
limited to, the following:
    (A) The currency of the country in which the QBU is a resident as 
determined under section 988(a)(3)(B);
    (B) The currencies of the QBU's cash flows;
    (C) The currencies in which the QBU generates revenues and incurs 
expenses;
    (D) The currencies in which the QBU borrows and lends;
    (E) The currencies of the QBU's sales markets;
    (F) The currencies in which pricing and other financial decisions 
are made;
    (G) The duration of the QBU's business operations; and
    (H) The significance and/or volume of the QBU's independent 
activities.
    (ii) Rate of inflation. The rate of inflation (regardless of how it 
is determined) shall not be a factor used to determine a QBU's economic 
environment.
    (iii) Consistency. A taxpayer must consistently apply the facts and 
circumstances test set forth in this paragraph (c)(2) in evaluating the 
economic environment of its QBUs, e.g., its branches, that engage in the 
same or similar trades or businesses.
    (3) Books and records presumption. A QBU shall be presumed to keep 
books and records in the currency of the economic environment in which a 
significant part of its activities are conducted. The presumption may be 
overcome only if the QBU can demonstrate to the satisfaction of the 
district director that a substantial nontax purpose exists for not 
keeping any books and records in such currency. A taxpayer

[[Page 543]]

may not use this presumption affirmatively in determining a QBU's 
functional currency.
    (4) Multiple currencies. If a QBU has more than one currency that 
satisfies the requirements of paragraph (c)(1) of this section, the QBU 
may choose any such currency as its functional currency.
    (5) Relationship of United States accounting principles. In making 
the functional currency determination under this paragraph (c), the 
currency of the QBU for purposes of United States generally accepted 
accounting principles (GAAP) will ordinarily be accepted as the 
functional currency of the QBU for income tax purposes, provided that 
the GAAP determination is based on facts and circumstances substantially 
similar to those set forth in paragraph (c)(2) of this section.
    (6) Effect of changed circumstances. Regardless of any change in 
circumstances, a QBU may change its functional currency determined under 
this paragraph (c) only if the QBU complies with Sec. 1.985-4 or the 
Commissioner's consent is considered to have been granted under Sec. 
1.985-2(d)(4) or Sec. 1.985-3(a)(2)(ii). For special rules relating to 
the conversion to the euro, see Sec. 1.985-8.
    (d) Single functional currency for a foreign corporation--(1) 
General rule. This paragraph (d) applies to a foreign corporation that 
has two or more QBUs that do not have the same functional currency. The 
foreign corporation shall be treated as having a single functional 
currency for the corporation as a whole that is different from the 
functional currency of one or more of its QBUs. The determination of a 
foreign corporation's functional currency shall be made by first 
applying paragraph (d)(1)(i) and then paragraph (d)(l)(ii) of this 
section.
    (i) Step 1. Each QBU of the foreign corporation determines its 
functional currency in accordance with the rules set forth in paragraphs 
(b) and (c) of this section and Sec. 1.985-2.
    (ii) Step 2. The foreign corporation determines its functional 
currency applying the principles of paragraphs (b) and (c) of this 
section to the corporation's activities as a whole. Thus, if a foreign 
corporation has two branches, the corporation shall determine its 
functional currency by applying the principles of paragraphs (b) and (c) 
of this section to the combined activities of the corporation and the 
branches. For purposes of this paragraph (d)(1), if a QBU of a foreign 
corporation has the dollar as its functional currency under paragraph 
(b)(2) of this section, the QBU's activities shall be considered dollar 
activities of the corporation.
    (2) Translation of income or loss of QBUs having different 
functional currencies than the foreign corporation as a whole. Where the 
functional currency of a foreign corporation as a whole differs from the 
functional currency of one or more of its QBUs, each such QBU shall 
determine the amount of its income or loss or earnings and profits (or 
deficit in earnings and profits) in its functional currency under the 
principles of section 987 (relating to branch transactions). The amount 
of income or loss or earnings and profits (or deficit in earnings and 
profits) of each QBU in its functional currency shall then be translated 
into the foreign corporation's functional currency using the appropriate 
exchange rate as defined in section 989(b)(4) for purposes of 
determining the corporation's income or loss or earnings and profits (or 
deficit in earnings and profits).
    (e) Translation of nonfunctional currency transactions. Except for a 
QBU using the dollar approximate separate transactions method described 
in Sec. 1.985-3, see section 988 and the regulations thereunder for the 
treatment of nonfunctional currency transactions.
    (f) Examples. The provisions of this section are illustrated by the 
following examples:

    Example 1. P, a domestic corporation, operates exclusively through 
foreign branch X in Country A. X is a QBU within the meaning of section 
989(a) and its residence is Country A as determined under section 988 
(a)(3)(B). The currency of Country A is the LC. All of X's purchases, 
sales, and expenses are in the LC. The laws of A require X to keep books 
and records in the LC. It is determined that the LC is the currency of X 
under United States generally accepted accounting principles. This 
determination is based on facts and circumstances substantially similar 
to those set forth in paragraph (c)(2) of this section. Under these 
facts, while the functional currency of P is the dollar since its 
residence

[[Page 544]]

is the United States, the functional currency of X is the LC.
    Example 2. P, a publicly-held domestic regulated investment company 
(as defined under section 851), operates exclusively through foreign 
branch B in Country R. B is a QBU within the meaning of section 989(a) 
and its residence is Country R as determined under section 988(a)(3)(B). 
The currency of Country R is the LC. B's principal activities consist of 
purchasing and selling stock and securities of Country R companies and 
securities issued by Country R. It is determined that the dollar is the 
currency of B under United States generally accepted accounting 
principles. This determination is not based on facts and circumstances 
substantially similar to those set forth in paragraph (c)(2) of this 
section. Under these facts, while the functional currency of P is the 
dollar since its residence is the United States, B may choose the LC as 
its functional currency because it has significant activities in the LC 
provided it keeps books and records in the LC. The fact that the dollar 
is the currency of B under generally accepted accounting principles is 
irrelevant for purposes of determining B's functional currency because 
the GAAP determination was not based on factors similar to those set 
forth in paragraph (c)(2) of this section.
    Example 3. P, a domestic bank, operates through foreign branch X in 
Country R. X is a QBU within the meaning of section 989(a) and its 
residence is Country R as determined under section 988(a)(3)(B). The 
currency of Country R is the LC. The laws of R require X to keep books 
and records in the LC. The branch customarily loans dollars and LCs. In 
the case of its LC loans, X ordinarily fixes the terms of the loans by 
reference to a contemporary London Inter-Bank Offered Rate (LIBOR) on 
dollar deposits. For instance, the interest on the amount of the 
outstanding LC loan principal might equal LIBOR plus 2 percent and the 
amount of the outstanding LC loan principal would be adjusted to reflect 
changes in the dollar value of the LC. X is primarily funded with 
dollar-denominated funds borrowed from related and unrelated parties. 
X's only LC activities are paying local taxes, employee wages, and local 
expenses such as rent and electricity. Under these facts, X's activities 
are primarily conducted in dollars. Thus, although X keeps its books and 
records in LCs, X's functional currency is the dollar.
    Example 4. S, a foreign corporation organized in Country U, is 
wholly-owned by P, a domestic corporation. The currency of Country U is 
the LC. S's sole function is acting as a financing vehicle for P and 
domestic corporations that are affiliated with P. All borrowing and 
lending transactions between S and P and its domestic affiliates are in 
dollars. Furthermore, primarily all of S's other borrowings are dollar-
denominated or based on a dollar index. S's only LC activities are 
paying local taxes, employee wages, and local expenses such as rent and 
electricity. S keeps its books and records in the LC. Under these facts, 
S's activities are primarily conducted in dollars. Thus, although S 
keeps its books and records in LCs, S's functional currency is the 
dollar.
    Example 5. D is a domestic corporation whose primary activity is the 
extraction of natural gas and oil through foreign branch X in Country Y. 
X is a QBU within the meaning of section 989(a) and its residence is 
Country Y as determined under section 988(a)(3)(B). The currency of 
Country Y is the LC. X bills a significant amount of its natural gas and 
oil sales in dollars and a significant amount in LCs. X also incurs 
significant LC and dollar expenses and liabilities. The laws of Country 
Y require X to keep its books and records in the LC. It is determined 
that the LC is the currency of X under United States generally accepted 
accounting principles. This determination is based on facts and 
circumstances substantially similar to those set forth in paragraph 
(c)(2) of this section. Absent other factors indicating that X primarily 
conducts its activities in the dollar, D could choose either the dollar 
or the LC as X's functional currency because X has significant 
activities in both the dollar and the LC, provided the books and records 
requirement is satisfied. If, instead, X's activities were determined to 
be primarily in the dollar, then X would have to use the dollar as its 
functional currency.
    Example 6. S, a foreign corporation organized in Country U, is 
wholly-owned by P, a domestic corporation. The currency of U is the LC. 
S purchases the products it sells from related and unrelated parties, 
including P. These purchases are made in the LC. In addition, most of 
S's gross receipts are generated by transactions denominated in the LC. 
S attempts to determine its LC price for goods sold in such a manner as 
to obtain an LC equivalent of a certain dollar amount after reduction 
for all LC costs. However, local market conditions sometimes result in 
pricing adjustments. Thus, changes in the LC-dollar exchange rate from 
period to period generally result in corresponding changes in the LC 
price of S's products. S pays local taxes, employee wages, and other 
local expenses in the LC. It is determined that the dollar is the 
currency of S under United States generally accepted accounting 
principles. This determination is not based on facts and circumstances 
substantially similar to those set forth in paragraph (c)(2) of this 
section. Under these facts, S could choose either the dollar or the LC 
as its functional currency because S has significant activities in both 
the dollar and the LC, provided that the books and records requirement 
is satisfied.

[[Page 545]]

    Example 7. S, a foreign corporation organized in Country X, is 
wholly-owned by P, a domestic corporation. S conducts all of its 
operations through two branches. Branch A is located in Country F and 
branch B is located in Country G. S, A, and B are QBUs within the 
meaning of section 989(a). Branch A's and branch B's residences are 
Country F and Country G respectively as determined under section 
988(a)(3)(B). The currency of Country F is the FC and the currency of 
Country G is the LC. The functional currencies of S, A, and B are 
determined in a two step procedure.
    Step 1: The functional currency of branches A and B. Branch A and 
branch B both conduct all activities in their respective local 
currencies. The FC is the currency of branch A and the LC is the 
currency of branch B under United States generally accepted accounting 
principles. This determination is based on facts and circumstances 
substantially similar to those set forth in paragraph (c)(2) of this 
section. Under these facts, the functional currency of branch A is the 
FC and the functional currency of branch B is the LC.
    Step 2: The functional currency of S. S's functional currency is 
determined by disregarding the fact that A and B are branches. When A's 
activities and B's activities are viewed as a whole, S determines that 
it only conducts significant activities in the LC. Therefore, S's 
functional currency is the LC. See Examples 9, 10, and 11 for how the 
earnings and profits of a foreign corporation, which has branches with 
different functional currencies, are determined.
    Example 8. Assume the same facts as in Example 7, except that S does 
not exist and P conducts all of its operations through branch A and 
branch B. In this instance P's functional currency in Step 2 is the 
dollar, regardless of the fact that its branches' activities viewed as a 
whole are in the LC, because P is a taxpayer whose residence is the 
United States under section 988(a)(3)(B)(i). Therefore, while the 
functional currency of branch A is the FC and the functional currency of 
branch B is the LC, the functional currency of P is the dollar because 
its residence is the United States.
    Example 9. The facts are the same as in Example 7. ln addition, 
assume that in 1987 branch A has earnings of 100 FC and branch B has 
earnings of 100 LC as determined under section 987. The weighted average 
exchange rate for the year is 1 FC/2 LC. Branch A's earnings are 
translated into 200 LC for purposes of computing S's earnings and 
profits in 1987. Thus, the total earnings and profits of S from branch A 
and branch B for 1987 is 300 LC.
    Example 10. (i) X, a foreign corporation organized in Country W, is 
wholly-owned by P, a domestic corporation. Both X and P are calendar 
year taxpayers that began business during 1987. X operates exclusively 
through two branches, A and B both of which are located outside of 
Country W. The functional currency of X and A is the LC, while the 
functional currency of B is the DC as determined under section 985 and 
Sec. 1.985-1. The earnings of B must be computed under section 987, 
relating to branch transactions. In 1987, A earns 900 LCs of nonsubpart 
F income and B earns 200 DCs of nonsubpart F income. Under section 
904(d)(2), A's income is financial service income and B's income is 
general limitation income. In order to determine X's earnings and 
profits, B's income must be translated into LCs (the functional currency 
of X). The weighted average exchange rate for 1987 is 1 LC/2 DC. Thus, 
in 1987 X's current earnings and profits (and its post-1986 
undistributed earnings) are 1000 LCs consisting of 900 LCs of financial 
services income earned by A and 100 LCs (200 DC/2) of general limitation 
income earned by B. Neither A nor B makes any remittances during 1987.
    (ii) In 1988, neither A nor B earns any income or generates any 
loss. On December 31, 1988, A remits 50 LCs directly to P. The 
remittance to P is considered to be remitted by A to X and then 
immediately distributed by X as a dividend. The 50 LC remittance does 
not result in an exchange gain or loss under section 987 to X because 
the functional currency of X and A is the LC. See section 987(3). Under 
section 904(d)(3)(D), the 50 LC dividend is treated as income in a 
separate category to the extent of the dividend's pro rata share of X's 
earnings and profits in each separate limitation category. Thus, 90 
percent, or 45 LCs, is treated as financial services income, and 10 
percent, or 5 LCs, is treated as general limitation income. After the 
dividend distribution, X has 950 LCs of accumulated earnings and profits 
(and post-1986 undistributed earnings) consisting of 855 LCs of 
financial service limitation income and 95 LCs of general limitation 
income.
    Example 11. The facts are the same as in Example 10, except that A 
makes no remittance during 1988 but B remits 120 DCs to X on December 
31, 1988, which X immediately converts into LCs, and X makes no dividend 
distribution during 1988. Assume that the appropriate exchange rate for 
the remittance is 1 LC/3 DCs. B's remittance triggers exchange loss to 
X. See section 987(3). Under section 987, the exchange loss on the 
remittance is 20 LCs calculated as follows: 40 LCs, which is the LC 
value of the 120 DC remittance (120 DCs/3), less 60 LCs, their LC basis 
(120 DCs/2). This loss is sourced and characterized under section 987 
and regulations thereunder.
    Example 12. F, a foreign corporation, has gain from the disposition 
of a United States real property interest (as defined in section 
897(c)). The gain is taken into account as if F were engaged in a trade 
or business within the United States during the taxable year

[[Page 546]]

and as if such gain were effectively connected with such trade or 
business. F's disposition activity shall be treated as a separate QBU 
with a dollar functional currency because such activity produced income 
that is treated as effectively connected with a trade or business within 
the United States. Therefore, F must compute its gain from the 
disposition by giving the United States real property interest an 
historic dollar basis.
