General Overview
Exchange Gains/Losses on Payables and Receivables Denominated in a Nonfunctional
Currency
This Concept Unit addresses the following issues related to computing an exchange gain or loss on payables and receivables of a
taxpayer:
1. General Rule
2. Booking Date
3. Details
4. Receivables
5. Payables
6. Spot Rate
Except as provided in regulations, a U.S. taxpayer’s functional currency is the U.S. dollar (USD). A Qualified Business Unit (QBU -
any separate and clearly identified unit of a taxpayer that maintains separate books and records) may have a non USD functional
currency if (1) the economic environment in which a significant part of the QBU’s activities are conducted is not the USD and (2) the
QBU is not keeping its books and records in the USD. See IRC 985(b); Treas. Reg. 1.985-1(b) and (c); note that U.S. Corporations
must generally have the USD as their functional currency, although their foreign branches that are QBUs may have non USD
functional currencies. A QBU can have a functional currency that is different from its owner. The functional currency is relevant for
taxpayers or QBU’s that have transactions in multiple currencies. Transactions are generally to be accounted for in the taxpayer's or
QBU’s functional currency. Certain non-functional currency transactions, called “Section 988 transactions” give rise to functional
currency gain or loss.

Transactions of U.S. corporations that require the use of a currency other then U.S. dollar have dramatically increased as more
taxpayers do business globally. Generally, when U.S. resident taxpayers invest and do business transactions in non US currency, all
federal tax determinations must be made in USD. Thus, Section 988 transactions, which are certain monetary transactions
denominated in (or determined by reference to the value of) a nonfunctional currency, may give rise to foreign exchange gains or
losses under Section 988.
General Overview cont’d
Exchange Gains/Losses on Payables and Receivables Denominated in a Nonfunctional
Currency
IRC 988 includes accruing, or otherwise taking into account, any item of expense or gross income or receipts which is to be paid or
received after the date on which such items is accrued or take into account if the amount the taxpayer is entitled to receive or is
required to pay is denominated in terms of a nonfunctional currency or is determined by reference to the value of one or more
nonfunctional currencies (e.g. payables and receivables held by a taxpayer or QBU that is denominated in nonfunctional currency.)

Relevant Key Factors
Exchange Gains/Losses on Payables and Receivables Denominated in a Nonfunctional
Currency
Key Factors
IRC 985 to 989 provide rules for determining a taxpayer or QBU’s functional currency, determining taxpayer’s income in its functional
currency and measuring foreign currency gain and losses. In general:
IRC 985 - Defines functional currency including hyperinflationary currency
IRC 986 - Addresses the determination of foreign taxes and foreign corporation’s earning and profits
IRC 987 - Addresses Branch transactions when the branch has a different functional currency from its owner
IRC 988 - Describes treatment of certain foreign currency transactions
IRC 989 - Defines a qualified business unit (QBU) and other terms
This Concept Unit will focus on the computation of exchange gains or losses on payables and receivables held by a taxpayer or QBU
in a currency other than its functional currency. See other concept, transaction, and process units for IRC 989, IRC 987 and other
foreign currency issues.
Note: The Internal Revenue Code (IRC) refers to “foreign currency gains and losses” while the Treasury Regulations use the
term “exchange gain or loss”.

Transaction #1: CFC1 provides
Service to USC resulting in an account
payable on USC books in Yen.
Both Transaction #1 and #2 will result in an exchange gain or loss under Section 988. In Transaction #1, USC will recognize an
exchange gain or loss on the account payable denominated in the Yen, a nonfunctional currency for USC. In Transaction #2, USC will
recognize an exchange gain or loss on the account receivable denominated in the Euro, a nonfunctional currency for USC. CFC1 and
CFC2 will not have Section 988 transactions since the transaction is denominated in each CFC’s respective functional currency.

Facts of Concept
Exchange Gains/Losses on Payables and Receivables Denominated in a Nonfunctional
Currency
Facts of Concept
It is very common for U.S. Companies to transact business in currencies other then the US dollar. An examiner needs to
understand:
the cash flow of these transactions
how they are recorded for financial accounting and tax purposes
any foreign currency gain or loss that should be reported, as well as the source (US or foreign) and character (ordinary or capital)
of the transaction.
Non-functional currency transaction amounts have to be translated into functional currency. An example of this type of transaction is
paying an invoice in a non-functional currency.
When the US taxpayer owns, or has a position in, a non US currency asset or liability; an examiner should be able to measure,
translate and establish when foreign currency gains and losses should be determined. This unit will focus on the exchange gains
and losses recognized by a taxpayer or QBU on the receipt or payment of an invoice, recorded on the books of the taxpayer or QBU
as an accounts receivable or payable respectively, that is denominated in a nonfunctional currency.

Detailed Explanation of the Concept
Exchange Gains/Losses on Payables and Receivables Denominated in a Nonfunctional
Currency
The starting point to applying the foreign currency tax rules is to determine the Taxpayer’s or QBU’s “functional currency.” This is the
currency in which all of the taxpayer’s or QBU’s taxable income and earnings and profits must be computed. Transactions, income
and foreign taxes in any other currency then must be translated back into the taxpayer’s functional currency under the rules of IRC
986, 987, 988 or 989.
Analysis Resources
Foreign Currency Gains and Losses (a.k.a. Exchange Gains and Losses):
The taxpayer or QBU computes foreign currency gains or losses on certain transactions
identified in IRC 988(c)(1)(B) and (C). Included in the listing of these transactions is the
accrual of any item of expense or income receipts that is paid or received after the accrual
date that is denominated in a currency other than the taxpayer or QBU’s functional currency
as defined in IRC 988(c)(1)(B)(ii) and Treas. Reg. 1.988(a)(2)(ii).
The description and computation of
exchange gains and losses on other
types of transactions discussed in
IRC 988(c)(1)(B) are discussed in
other IPS units listed at the end of
this unit.
Recognition Date on Payables and Receivables:
The exchange gain or loss on the above identified transaction (accruals of items of expense
or income) is recognized on the date that the payment of nonfunctional currency is made or
received. Such gain or loss is recognized in accordance with the applicable recognition
provisions of the IRC. If a taxpayers or QBU’s right to receive income or pay an expense is
transferred or modified in a transaction in which gain or loss would otherwise be recognized,
exchange gain or loss is recognized only to the extent of total gain or loss on the
transaction.
See Treas. Reg. 1.988-2(c)(1).

currency in which all of the taxpayer’s or QBU’s taxable income and earnings and profits must be computed. Transactions, income
and foreign taxes in any other currency then must be translated back into the taxpayer’s functional currency under the rules of IRC
986, 987, 988 or 989.
Analysis Resources
Source of Section 988 gain:
The source of foreign currency gain or loss is determined by reference to the residence of
the taxpayer or QBU of the taxpayer on whose books the underlying asset, liability, or item
of income or expense is properly reflected. Whether an asset, liability, or item of income or
expense is properly reflected on the books of a QBU is a question of fact.
For further discussion regarding the
identification and determination of a
taxpayer’s QBUs, please see IPS
Concept Unit “Definition of a QBU”.
See Treas. Reg. 1.988-4(a) and (b).
Computation of Exchange Gain/Loss on Item of Gross Income or Receipt (Accounts
Receivable):
The exchange gain loss on an item of gross income or receipt (recorded as an account
receivable) that is denominated in a nonfunctional currency is computed by subtracting the
nonfunctional currency accrued as an account receivable (multiplied by the spot rate at the
booking date) from the nonfunctional currency received as payment on the account
receivable (multiplied by the spot rate on the payment date).
See Treas. Reg. 1.988-2(c)(2).

transaction, and the relevant authority.
Analysis Resources
Computation of Exchange Gain/Loss on Item of Expense (Accounts Payable):
The exchange gain or loss on an item of expense (recorded as an accounts payable) that is
denominated in a nonfunctional currency is computed by subtracting the nonfunctional
currency paid on the account payable (multiplied by the spot rate at the payment date) from
the nonfunctional currency accrued as an account payable (multiplied by the spot rate on
the booking date).
NOTE: Payment of a payable might result in a separate Section 988 transaction for
disposition of nonfunctional currency.
See Treas. Reg. 1.988-2(c)(3).
Spot Rate Option: The Treasury Regulation allows a taxpayer or QBU to utilize a spot rate
convention to be determined at intervals of one quarter year or less (versus the spot rate at
the actual booking or payment dates) when computing exchange gains and losses on
nonfunctional currency accounts receivables and payables.
See Treas. Reg. 1.988-1(d)(3).
Recognition Date: The date that payment is made or received. Treas. Reg. 1.988-2(c)(1)
Exchange Gain or Loss on item of gross income or receipt (receipt of account receivable):
[(Nonfunctional currency received) x (spot rate on payment date)] [(nonfunctional currency
accrued) x (spot rate on booking date)]
Treas. Reg. 1.988-2(c)(2)
Exchange Gain or Loss on item of expense (payment of account payable): [(Nonfunctional
currency accrued) x (spot rate on booking date)] [(nonfunctional currency paid) x (spot rate

Examples of the Concept
Exchange Gains/Losses on Payables and Receivables Denominated in a Nonfunctional
Currency
Example Exchange Gain/Loss on Payment of an Account Payable in Nonfunctional Currency
USC is a calendar year corporation with the
USD as its functional currency.
On 01/15/20x9, USC purchases inventory on
account from CFC1 for LC $10,000. The spot
rate on 01/15/20x9 is LC $1.00 = US $0.55.
On 02/23/20x9, when USC makes payment of
the LC $10,000 payable, the spot rate is LC
$1.00 = US $0.50.
On 02/23/20x9, USC will realize an exchange
gain on the LC $10,000 account payable.
USC’s gain is computed by multiplying the LC
$10,000 by the spot rate on the booking date
(LC $10,000 x 0.55 = US $5,500) and
subtracting from such amount, the amount
computed by multiplying the LC $10,000 by the
spot rate on the payment date (LC $10,000 x
0.50 = US $5,000).
Thus, USC’s exchange gain on the transaction
is US $500 (US $5,500 US $5,000). The
character of the exchange gain is ordinary.
NOTE: There could be an exchange gain or loss
on the disposition of LC by USC depending on
when USC acquires LC.

Examples of the Concept
Exchange Gains/Losses on Payables and Receivables Denominated in a Nonfunctional
Currency
USC is a calendar year corporation with the
USD as its functional currency.
On 01/15/20x9, USC sells inventory to CFC2
for LC $10,000. The spot rate on 01/15/20x9 is
LC $1.00 = US $0.55.
On 02/23/20x9, when USC receives payment,
of the LC $10,000, the spot rate is LC $1.00 =
US $0.50.
On 02/23/20x9, USC will realize an exchange
loss. USC’s loss is computed by multiplying
the LC $10,000 by the spot rate on the date the
LC $10,000 are received (LC $10,000 x 0.50 =
US $5,000) and subtracting from such amount,
the amount computed by multiplying the LC
$10,000 by the spot rate on the booking date
(LC $10,000 x 0.55 = US $5,500).
Thus, USC’s exchange loss on the transaction
is US $500 (US $5,000 US $5,500). The
character of the exchange loss is ordinary.

Examples of the Concept
Exchange Gains/Losses on Payables and Receivables Denominated in a Nonfunctional
Currency
Example Spot Rate Convention Option (Monthly Basis)
USC is a calendar year corporation with the
USD as its functional currency.
USC uses a spot rate convention to determine
the spot rate as provided in Treas. Reg. 1.988-
1(d)(3)
The spot rate determined under the spot rate
convention for the month of January is LC
$1.00 = US $ 0.54, and for the month of
February is LC $1.00 = US $ 0.51.
On 01/15/20x9, USC sells inventory for LC
$10,000. On 02/23/20x9, USC receives
payment of the LC $10,000.
On the last date in February, USC will realize
exchange loss. USC’s loss is computed by
multiplying the LC $10,000 by the spot rate
convention for the month of February (LC
$10,000 x US $0.51 = US $5,100) and
subtracting from such amount, the amount
computed by multiplying the LC $10,000 by the
spot rate convention for the month of January
(LC $10,000 x US $0.54 = US $5,400)
USC’s exchange loss is $300 (US $5,100 US
$ 5,400). (Source: Treas. Reg. 1.988-2(c)(4),
