26 CFR §1.988-6

1. (a)In general
   1. (1)Scope. This section determines the accrual of interest and the amount, timing, source, and character of any gain or loss on nonfunctional currency contingent payment debt instruments described in this paragraph (a)(1) and to which § 1.1275-4(a) would otherwise apply if the debt instrument were denominated in the taxpayer's functional currency. Except as provided by the rules in this section, the rules in § 1.1275-4 (relating to contingent payment debt instruments) apply to the following instruments—
      1. (i)A debt instrument described in § 1.1275-4(b)(1) for which all payments of principal and interest are denominated in, or determined by reference to, a single nonfunctional currency and which has one or more non-currency related contingencies;
      2. (ii)A debt instrument described in § 1.1275-4(b)(1) for which payments of principal or interest are denominated in, or determined by reference to, more than one currency and which has no non-currency related contingencies;
      3. (iii)A debt instrument described in § 1.1275-4(b)(1) for which payments of principal or interest are denominated in, or determined by reference to, more than one currency and which has one or more non-currency related contingencies; and
      4. (iv)A debt instrument otherwise described in paragraph (a)(1)(i), (ii) or (iii) of this section, except that the debt instrument is described in § 1.1275-4(c)(1) rather than § 1.1275-4(b)(1) (e.g., the instrument is issued for non-publicly traded property).
   2. (2)Exception for hyperinflationary currencies
      1. (i)In general. Except as provided in paragraph (a)(2)(ii) of this section, this section shall not apply to an instrument described in paragraph (a)(1) of this section if any payment made under such instrument is determined by reference to a hyperinflationary currency, as defined in § 1.985-1(b)(2)(ii)(D). In such case, the amount, timing, source and character of interest, principal, foreign currency gain or loss, and gain or loss relating to a non-currency contingency shall be determined under the method that reflects the instrument's economic substance.
      2. (ii)Discretion as to method. If a taxpayer does not account for an instrument described in paragraph (a)(2)(i) of this section in a manner that reflects the instrument's economic substance, the Commissioner may apply the rules of this section to such an instrument or apply the principles of § 1.988-2(b)(15), reasonably taking into account the contingent feature or features of the instrument.
2. (b)Instruments described in paragraph (a)(1)(i) of this section
   1. (1)In general. Paragraph (b)(2) of this section provides rules for applying the noncontingent bond method (as set forth in § 1.1275-4(b)) in the nonfunctional currency in which a debt instrument described in paragraph (a)(1)(i) of this section is denominated, or by reference to which its payments are determined (the denomination currency). Paragraph (b)(3) of this section describes how amounts determined in paragraph (b)(2) of this section shall be translated from the denomination currency of the instrument into the taxpayer's functional currency. Paragraph (b)(4) of this section describes how gain or loss (other than foreign currency gain or loss) shall be determined and characterized with respect to the instrument. Paragraph (b)(5) of this section describes how foreign currency gain or loss shall be determined with respect to accrued interest and principal on the instrument. Paragraph (b)(6) of this section provides rules for determining the source and character of any gain or loss with respect to the instrument. Paragraph (b)(7) of this section provides rules for subsequent holders of an instrument who purchase the instrument for an amount other than the adjusted issue price of the instrument. Paragraph (c) of this section provides examples of the application of paragraph (b) of this section. See paragraph (d) of this section for the determination of the denomination currency of an instrument described in paragraph (a)(1)(ii) or (iii) of this section. See paragraph (e) of this section for the treatment of an instrument described in paragraph (a)(1)(iv) of this section.
   2. (2)Application of noncontingent bond method
      1. (i)Accrued interest. Interest accruals on an instrument described in paragraph (a)(1)(i) of this section are initially determined in the denomination currency of the instrument by applying the noncontingent bond method, set forth in § 1.1275-4(b), to the instrument in its denomination currency. Accordingly, the comparable yield, projected payment schedule, and comparable fixed rate debt instrument, described in § 1.1275-4(b)(4), are determined in the denomination currency. For purposes of applying the noncontingent bond method to instruments described in this paragraph, the applicable Federal rate described in § 1.1275-4(b)(4)(i) shall be the rate described in § 1.1274-4(d) with respect to the denomination currency.
      2. (ii)Net positive and negative adjustments. Positive and negative adjustments, and net positive and net negative adjustments, with respect to an instrument described in paragraph (a)(1)(i) of this section are determined by applying the rules of § 1.1275-4(b)(6) (and § 1.1275-4(b)(9)(i) and (ii), if applicable) in the denomination currency. Accordingly, a net positive adjustment is treated as additional interest (in the denomination currency) on the instrument. A net negative adjustment first reduces interest that otherwise would be accrued by the taxpayer during the current tax year in the denomination currency. If a net negative adjustment exceeds the interest that would otherwise be accrued by the taxpayer during the current tax year in the denomination currency, the excess is treated as ordinary loss (if the taxpayer is a holder of the instrument) or ordinary income (if the taxpayer is the issuer of the instrument). The amount treated as ordinary loss by a holder with respect to a net negative adjustment is limited, however, to the amount by which the holder's total interest inclusions on the debt instrument (determined in the denomination currency) exceed the total amount of the holder's net negative adjustments treated as ordinary loss on the debt instrument in prior taxable years (determined in the denomination currency). Similarly, the amount treated as ordinary income by an issuer with respect to a net negative adjustment is limited to the amount by which the issuer's total interest deductions on the debt instrument (determined in the denomination currency) exceed the total amount of the issuer's net negative adjustments treated as ordinary income on the debt instrument in prior taxable years (determined in the denomination currency). To the extent a net negative adjustment exceeds the current year's interest accrual and the amount treated as ordinary loss to a holder (or ordinary income to the issuer), the excess is treated as a negative adjustment carryforward, within the meaning of § 1.1275-4(b)(6)(iii)(C), in the denomination currency.
      3. (iii)Adjusted issue price. The adjusted issue price of an instrument described in paragraph (a)(1)(i) of this section is determined by applying the rules of § 1.1275-4(b)(7) in the denomination currency. Accordingly, the adjusted issue price is equal to the debt instrument's issue price in the denomination currency, increased by the interest previously accrued on the debt instrument (determined without regard to any net positive or net negative adjustments on the instrument) and decreased by the amount of any noncontingent payment and the projected amount of any contingent payment previously made on the instrument. All adjustments to the adjusted issue price are calculated in the denomination currency.
      4. (iv)Adjusted basis. The adjusted basis of an instrument described in paragraph (a)(1)(i) of this section is determined by applying the rules of § 1.1275-4(b)(7) in the taxpayer's functional currency. In accordance with those rules, a holder's basis in the debt instrument is increased by the interest previously accrued on the debt instrument (translated into functional currency), without regard to any net positive or net negative adjustments on the instrument (except as provided in paragraph (b)(7) or (8) of this section, if applicable), and decreased by the amount of any noncontingent payment and the projected amount of any contingent payment previously made on the instrument to the holder (translated into functional currency). See paragraph (b)(3)(iii) of this section for translation rules.
      5. (v)Amount realized. The amount realized by a holder and the repurchase price paid by the issuer on the scheduled or unscheduled retirement of a debt instrument described in paragraph (a)(1)(i) of this section are determined by applying the rules of § 1.1275-4(b)(7) in the denomination currency. For example, with regard to a scheduled retirement at maturity, the holder is treated as receiving the projected amount of any contingent payment due at maturity, reduced by the amount of any negative adjustment carryforward. For purposes of translating the amount realized by the holder into functional currency, the rules of paragraph (b)(3)(iv) of this section shall apply.
   3. (3)Treatment and translation of amounts determined under noncontingent bond method
      1. (i)Accrued interest. The amount of accrued interest, determined under paragraph (b)(2)(i) of this section, is translated into the taxpayer's functional currency at the average exchange rate, as described in § 1.988-2(b)(2)(iii)(A), or, at the taxpayer's election, at the appropriate spot rate, as described in § 1.988-2(b)(2)(iii)(B).
      2. (ii)Net positive and negative adjustments
         1. (A)Net positive adjustments. A net positive adjustment, as referenced in paragraph (b)(2)(ii) of this section, is translated into the taxpayer's functional currency at the spot rate on the last day of the taxable year in which the adjustment is taken into account under § 1.1275-4(b)(6), or, if earlier, the date the instrument is disposed of or otherwise terminated.
         2. (B)Net negative adjustments. A net negative adjustment is treated and, where necessary, is translated from the denomination currency into the taxpayer's functional currency under the following rules:
            1. (1)The amount of a net negative adjustment determined in the denomination currency that reduces the current year's interest in that currency shall first reduce the current year's accrued but unpaid interest, and then shall reduce the current year's interest which was accrued and paid. No translation is required.
            2. (2)The amount of a net negative adjustment treated as ordinary income or loss under § 1.1275-4(b)(6)(iii)(B) first is attributable to accrued but unpaid interest accrued in prior taxable years. For this purpose, the net negative adjustment shall be treated as attributable to any unpaid interest accrued in the immediately preceding taxable year, and thereafter to unpaid interest accrued in each preceding taxable year. The amount of the net negative adjustment applied to accrued but unpaid interest is translated into functional currency at the same rate used, in each of the respective prior taxable years, to translate the accrued interest.
            3. (3)Any amount of the net negative adjustment remaining after the application of paragraphs (b)(3)(ii)(B)(1) and (2) of this section is attributable to interest accrued and paid in prior taxable years. The amount of the net negative adjustment applied to such amounts is translated into functional currency at the spot rate on the date the debt instrument was issued or, if later, acquired.
            4. (4)Any amount of the net negative adjustment remaining after application of paragraphs (b)(3)(ii)(B)(1), (2) and (3) of this section is a negative adjustment carryforward, within the meaning of § 1.1275-4(b)(6)(iii)(C). A negative adjustment carryforward is carried forward in the denomination currency and is applied to reduce interest accruals in subsequent years. In the year in which the instrument is sold, exchanged or retired, any negative adjustment carryforward not applied to interest reduces the holder's amount realized on the instrument (in the denomination currency). An issuer of a debt instrument described in paragraph (a)(1)(i) of this section who takes into income a negative adjustment carryforward (that is not applied to interest) in the year the instrument is retired, as described in § 1.1275-4(b)(6)(iii)(C), translates such income into functional currency at the spot rate on the date the instrument was issued.
      3. (iii)Adjusted basis
         1. (A)In general. Except as otherwise provided in this paragraph and paragraph (b)(7) or (8) of this section, a holder determines and maintains adjusted basis by translating the denomination currency amounts determined under § 1.1275-4(b)(7)(iii) into functional currency as follows:
            1. (1)The holder's initial basis in the instrument is determined by translating the amount paid by the holder to acquire the instrument (in the denomination currency) into functional currency at the spot rate on the date the instrument was issued or, if later, acquired.
            2. (2)An increase in basis attributable to interest accrued on the instrument is translated at the rate applicable to such interest under paragraph (b)(3)(i) of this section.
            3. (3)Any noncontingent payment and the projected amount of any contingent payments determined in the denomination currency that decrease the holder's basis in the instrument under § 1.1275-4(b)(7)(iii) are translated as follows:
               1. (i)The payment first is attributable to the most recently accrued interest to which prior amounts have not already been attributed. The payment is translated into functional currency at the rate at which the interest was accrued.
               2. (ii)Any amount remaining after the application of paragraph (b)(3)(iii)(A)(3)(i) of this section is attributable to principal. Such amounts are translated into functional currency at the spot rate on the date the instrument was issued or, if later, acquired.
         2. (B)Exception for interest reduced by a negative adjustment carryforward. Solely for purposes of this § 1.988-6, any amounts of accrued interest income that are reduced as a result of a negative adjustment carryforward shall be treated as principal and translated at the spot rate on the date the instrument was issued or, if later, acquired.
      4. (iv)Amount realized
         1. (A)Instrument held to maturity
            1. (1)In general. With respect to an instrument held to maturity, a holder translates the amount realized by separating such amount in the denomination currency into the component parts of interest and principal that make up adjusted basis prior to translation under paragraph (b)(3)(iii) of this section, and translating each of those component parts of the amount realized at the same rate used to translate the respective component parts of basis under paragraph (b)(3)(iii) of this section. The amount realized first shall be translated by reference to the component parts of basis consisting of accrued interest during the taxpayer's holding period as determined under paragraph (b)(3)(iii) of this section and ordering such amounts on a last in first out basis. Any remaining portion of the amount realized shall be translated by reference to the rate used to translate the component of basis consisting of principal as determined under paragraph (b)(3)(iii) of this section.
            2. (2)Subsequent purchases at discount and fixed but deferred contingent payments. For purposes of this paragraph (b)(3)(iv) of this section, any amount which is required to be added to adjusted basis under paragraph (b)(7) or (8) of this section shall be treated as additional interest which was accrued on the date the amount was added to adjusted basis. To the extent included in amount realized, such amounts shall be translated into functional currency at the same rates at which they were translated for purposes of determining adjusted basis. See paragraphs (b)(7)(iv) and (b)(8) of this section for rules governing the rates at which the amounts are translated for purposes of determining adjusted basis.
         2. (B)Sale, exchange, or unscheduled retirement
            1. (1)Holder. In the case of a sale, exchange, or unscheduled retirement, application of the rule stated in paragraph (b)(3)(iv)(A) of this section shall be as follows. The holder's amount realized first shall be translated by reference to the principal component of basis as determined under paragraph (b)(3)(iii) of this section, and then to the component of basis consisting of accrued interest as determined under paragraph (b)(3)(iii) of this section and ordering such amounts on a first in first out basis. Any gain recognized by the holder (i.e., any excess of the sale price over the holder's basis, both expressed in the denomination currency) is translated into functional currency at the spot rate on the payment date.
            2. (2)Issuer. In the case of an unscheduled retirement of the debt instrument, any excess of the adjusted issue price of the debt instrument over the amount paid by the issuer (expressed in denomination currency) shall first be attributable to accrued unpaid interest, to the extent the accrued unpaid interest had not been previously offset by a negative adjustment, on a last-in-first-out basis, and then to principal. The accrued unpaid interest shall be translated into functional currency at the rate at which the interest was accrued. The principal shall be translated at the spot rate on the date the debt instrument was issued.
         3. (C)Effect of negative adjustment carryforward with respect to the issuer. Any amount of negative adjustment carryforward treated as ordinary income under § 1.1275-4(b)(6)(iii)(C) shall be translated at the exchange rate on the day the debt instrument was issued.
   4. (4)Determination of gain or loss not attributable to foreign currency. A holder of a debt instrument described in paragraph (a)(1)(i) of this section shall recognize gain or loss upon sale, exchange, or retirement of the instrument equal to the difference between the amount realized with respect to the instrument, translated into functional currency as described in paragraph (b)(3)(iv) of this section, and the adjusted basis in the instrument, determined and maintained in functional currency as described in paragraph (b)(3)(iii) of this section. The amount of any gain or loss so determined is characterized as provided in § 1.1275-4(b)(8), and sourced as provided in paragraph (b)(6) of this section.
   5. (5)Determination of foreign currency gain or loss
      1. (i)In general. Other than in a taxable disposition of the debt instrument, foreign currency gain or loss is recognized with respect to a debt instrument described in paragraph (a)(1)(i) of this section only when payments are made or received. No foreign currency gain or loss is recognized with respect to a net positive or negative adjustment, as determined under paragraph (b)(2)(ii) of this section (except with respect to a positive adjustment described in paragraph (b)(8) of this section). As described in this paragraph (b)(5), foreign currency gain or loss is determined in accordance with the rules of § 1.988-2(b).
      2. (ii)Foreign currency gain or loss attributable to accrued interest. The amount of foreign currency gain or loss recognized with respect to payments of interest previously accrued on the instrument is determined by translating the amount of interest paid or received into functional currency at the spot rate on the date of payment and subtracting from such amount the amount determined by translating the interest paid or received into functional currency at the rate at which such interest was accrued under the rules of paragraph (b)(3)(i) of this section. For purposes of this paragraph, the amount of any payment that is treated as accrued interest shall be reduced by the amount of any net negative adjustment treated as ordinary loss (to the holder) or ordinary income (to the issuer), as provided in paragraph (b)(2)(ii) of this section. For purposes of determining whether the payment consists of interest or principal, see the payment ordering rules in paragraph (b)(5)(iv) of this section.
      3. (iii)Principal. The amount of foreign currency gain or loss recognized with respect to payment or receipt of principal is determined by translating the amount paid or received into functional currency at the spot rate on the date of payment or receipt and subtracting from such amount the amount determined by translating the principal into functional currency at the spot rate on the date the instrument was issued or, in case of the holder, if later, acquired. For purposes of determining whether the payment consists of interest or principal, see the payment ordering rules in paragraph (b)(5)(iv) of this section.
      4. (iv)Payment ordering rules
         1. (A)In general. Except as provided in paragraph (b)(5)(iv)(B) of this section, payments with respect to an instrument described in paragraph (a)(1)(i) of this section shall be treated as follows:
            1. (1)A payment shall first be attributable to any net positive adjustment on the instrument that has not previously been taken into account.
            2. (2)Any amount remaining after applying paragraph (b)(5)(iv)(A)(1) of this section shall be attributable to accrued but unpaid interest, remaining after reduction by any net negative adjustment, and shall be attributable to the most recent accrual period to the extent prior amounts have not already been attributed to such period.
            3. (3)Any amount remaining after applying paragraphs (b)(5)(iv)(A)(1) and (2) of this section shall be attributable to principal. Any interest paid in the current year that is reduced by a net negative adjustment shall be considered a payment of principal for purposes of determining foreign currency gain or loss.
         2. (B)Special rule for sale or exchange or unscheduled retirement. Payments made or received upon a sale or exchange or unscheduled retirement shall first be applied against the principal of the debt instrument (or in the case of a subsequent purchaser, the purchase price of the instrument in denomination currency) and then against accrued unpaid interest (in the case of a holder, accrued while the holder held the instrument).
         3. (C)Subsequent purchaser that has a positive adjustment allocated to a daily portion of interest. A positive adjustment that is allocated to a daily portion of interest pursuant to paragraph (b)(7)(iv) of this section shall be treated as interest for purposes of applying the payment ordering rule of this paragraph (b)(5)(iv).
   6. (6)Source of gain or loss. The source of foreign currency gain or loss recognized with respect to an instrument described in paragraph (a)(1)(i) of this section shall be determined pursuant to § 1.988-4. Consistent with the rules of § 1.1275-4(b)(8), all gain (other than foreign currency gain) on an instrument described in paragraph (a)(1)(i) of this section is treated as interest income for all purposes. The source of an ordinary loss (other than foreign currency loss) with respect to an instrument described in paragraph (a)(1)(i) of this section shall be determined pursuant to § 1.1275-4(b)(9)(iv). The source of a capital loss with respect to an instrument described in paragraph (a)(1)(i) of this section shall be determined pursuant to § 1.865-1(b)(2).
   7. (7)Basis different from adjusted issue price
      1. (i)In general. The rules of § 1.1275-4(b)(9)(i), except as set forth in this paragraph (b)(7), shall apply to an instrument described in paragraph (a)(1)(i) of this section purchased by a subsequent holder for more or less than the instrument's adjusted issue price.
      2. (ii)Determination of basis. If an instrument described in paragraph (a)(1)(i) of this section is purchased by a subsequent holder, the subsequent holder's initial basis in the instrument shall equal the amount paid by the holder to acquire the instrument, translated into functional currency at the spot rate on the date of acquisition.
      3. (iii)Purchase price greater than adjusted issue price. If the purchase price of the instrument (determined in the denomination currency) exceeds the adjusted issue price of the instrument, the holder shall, consistent with the rules of § 1.1275-4(b)(9)(i)(B), reasonably allocate such excess to the daily portions of interest accrued on the instrument or to a projected payment on the instrument. To the extent attributable to interest, the excess shall be reasonably allocated over the remaining term of the instrument to the daily portions of interest accrued and shall be a negative adjustment on the dates the daily portions accrue. On the date of such adjustment, the holder's adjusted basis in the instrument is reduced by the amount treated as a negative adjustment under this paragraph (b)(7)(iii), translated into functional currency at the rate used to translate the interest which is offset by the negative adjustment. To the extent related to a projected payment, such excess shall be treated as a negative adjustment on the date the payment is made. On the date of such adjustment, the holder's adjusted basis in the instrument is reduced by the amount treated as a negative adjustment under this paragraph (b)(7)(iii), translated into functional currency at the spot rate on the date the instrument was acquired.
      4. (iv)Purchase price less than adjusted issue price. If the purchase price of the instrument (determined in the denomination currency) is less than the adjusted issue price of the instrument, the holder shall, consistent with the rules of § 1.1275-4(b)(9)(i)(C), reasonably allocate the difference to the daily portions of interest accrued on the instrument or to a projected payment on the instrument. To the extent attributable to interest, the difference shall be reasonably allocated over the remaining term of the instrument to the daily portions of interest accrued and shall be a positive adjustment on the dates the daily portions accrue. On the date of such adjustment, the holder's adjusted basis in the instrument is increased by the amount treated as a positive adjustment under this paragraph (b)(7)(iv), translated into functional currency at the rate used to translate the interest to which it relates. For purposes of determining adjusted basis under paragraph (b)(3)(iii) of this section, such increase in adjusted basis shall be treated as an additional accrual of interest during the period to which the positive adjustment relates. To the extent related to a projected payment, such difference shall be treated as a positive adjustment on the date the payment is made. On the date of such adjustment, the holder's adjusted basis in the instrument is increased by the amount treated as a positive adjustment under this paragraph (b)(7)(iv), translated into functional currency at the spot rate on the date the adjustment is taken into account. For purposes of determining the amount realized on the instrument in functional currency under paragraph (b)(3)(iv) of this section, amounts attributable to the excess of the adjusted issue price of the instrument over the purchase price of the instrument shall be translated into functional currency at the same rate at which the corresponding adjustments are taken into account under this paragraph (b)(7)(iv) for purposes of determining the adjusted basis of the instrument.
   8. (8)Fixed but deferred contingent payments. In the case of an instrument with a contingent payment that becomes fixed as to amount before the payment is due, the rules of § 1.1275-4(b)(9)(ii) shall be applied in the denomination currency of the instrument. For this purpose, foreign currency gain or loss shall be recognized on the date payment is made or received with respect to the instrument under the principles of paragraph (b)(5) of this section. Any increase or decrease in basis required under § 1.1275-4(b)(9)(ii)(D) shall be taken into account at the same exchange rate as the corresponding net positive or negative adjustment is taken into account.
3. (c)Examples. The provisions of paragraph (b) of this section may be illustrated by the following examples. In each example, assume that the instrument described is a debt instrument for federal income tax purposes. No inference is intended, however, as to whether the instrument is a debt instrument for federal income tax purposes. The examples are as follows:
4. (d)Multicurrency debt instruments
   1. (1)In general. Except as provided in this paragraph (d), a multicurrency debt instrument described in paragraph (a)(1)(ii) or (iii) of this section shall be treated as an instrument described in paragraph (a)(1)(i) of this section and shall be accounted for under the rules of paragraph (b) of this section. Because payments on an instrument described in paragraph (a)(1)(ii) or (iii) of this section are denominated in, or determined by reference to, more than one currency, the issuer and holder or holders of the instrument are required to determine the denomination currency of the instrument under paragraph (d)(2) of this section before applying the rules of paragraph (b) of this section.
   2. (2)Determination of denomination currency
      1. (i)In general. The denomination currency of an instrument described in paragraph (a)(1)(ii) or (iii) of this section shall be the predominant currency of the instrument. Except as otherwise provided in paragraph (d)(2)(ii) of this section, the predominant currency of the instrument shall be the currency with the greatest value determined by comparing the functional currency value of the noncontingent and projected payments denominated in, or determined by reference to, each currency on the issue date, discounted to present value (in each relevant currency), and translated (if necessary) into functional currency at the spot rate on the issue date. For this purpose, the applicable discount rate may be determined using any method, consistently applied, that reasonably reflects the instrument's economic substance. If a taxpayer does not determine a discount rate using such a method, the Commissioner may choose a method for determining the discount rate that does reflect the instrument's economic substance. The predominant currency is determined as of the issue date and does not change based on subsequent events (e.g., changes in value of one or more currencies).
      2. (ii)Difference in discount rate of greater than 10 percentage points. This § 1.988-6(d)(2)(ii) applies if no currency has a value determined under paragraph (d)(2)(i) of this section that is greater than 50% of the total value of all payments. In such a case, if the difference between the discount rate in the denomination currency otherwise determined under (d)(2)(i) of this section and the discount rate determined under paragraph (d)(2)(i) of this section with respect to any other currency in which payments are made (or determined by reference to) pursuant to the instrument is greater than 10 percentage points, then the Commissioner may determine the predominant currency under any reasonable method.
   3. (3)Issuer/holder consistency. The issuer determines the denomination currency under the rules of paragraph (d)(2) of this section and provides this information to the holders of the instrument in a manner consistent with the issuer disclosure rules of § 1.1275-2(e). If the issuer does not determine the denomination currency of the instrument, or if the issuer's determination is unreasonable, the holder of the instrument must determine the denomination currency under the rules of paragraph (d)(2) of this section. A holder that determines the denomination currency itself must explicitly disclose this fact on a statement attached to the holder's timely filed federal income tax return for the taxable year that includes the acquisition date of the instrument.
   4. (4)Treatment of payments in currencies other than the denomination currency. For purposes of applying the rules of paragraph (b) of this section to debt instruments described in paragraph (a)(1)(ii) or (iii) of this section, payments not denominated in (or determined by reference to) the denomination currency shall be treated as non-currency-related contingent payments. Accordingly, if the denomination currency of the instrument is determined to be the taxpayer's functional currency, the instrument shall be accounted for under § 1.1275-4(b) rather than under this section.
5. (e)Instruments issued for nonpublicly traded property
   1. (1)Applicability. This paragraph (e) applies to debt instruments issued for nonpublicly traded property that would be described in paragraph (a)(1)(i), (ii), or (iii) of this section, but for the fact that such instruments are described in § 1.1275-4(c)(1) rather than § 1.1275-4(b)(1). For example, this paragraph (e) generally applies to a contingent payment debt instrument denominated in a nonfunctional currency that is issued for non-publicly traded property. Generally the rules of § 1.1275-4(c) apply except as set forth by the rules of this paragraph (e).
   2. (2)Separation into components. An instrument described in this paragraph (e) is not accounted for using the noncontingent bond method of § 1.1275-4(b) and paragraph (b) of this section. Rather, the instrument is separated into its component payments. Each noncontingent payment or group of noncontingent payments which is denominated in a single currency shall be considered a single component treated as a separate debt instrument denominated in the currency of the payment or group of payments. Each contingent payment shall be treated separately as provided in paragraph (e)(4) of this section.
   3. (3)Treatment of components consisting of one or more noncontingent payments in the same currency. The issue price of each component treated as a separate debt instrument which consists of one or more noncontingent payments is the sum of the present values of the noncontingent payments contained in the separate instrument. The present value of any noncontingent payment shall be determined under § 1.1274-2(c)(2), and the test rate shall be determined under § 1.1274-4 with respect to the currency in which each separate instrument is considered denominated. No interest payments on the separate debt instrument are qualified stated interest payments (within the meaning of § 1.1273-1(c)) and the de minimis rules of section 1273(a)(3) and § 1.1273-1(d) do not apply to the separate debt instrument. Interest income or expense is translated, and exchange gain or loss is recognized on the separate debt instrument as provided in § 1.988-2(b)(2), if the instrument is denominated in a nonfunctional currency.
   4. (4)Treatment of components consisting of contingent payments
      1. (i)General rule. A component consisting of a contingent payment shall generally be treated in the manner provided in § 1.1275-4(c)(4). However, except as provided in paragraph (e)(4)(ii) of this section, the test rate shall be determined by reference to the U.S. dollar unless the dollar does not reasonably reflect the economic substance of the contingent component. In such case, the test rate shall be determined by reference to the currency which most reasonably reflects the economic substance of the contingent component. Any amount received in nonfunctional currency from a component consisting of a contingent payment shall be translated into functional currency at the spot rate on the date of receipt. Except in the case when the payment becomes fixed more than six months before the payment is due, no foreign currency gain or loss shall be recognized on a contingent payment component.
      2. (ii)Certain delayed contingent payments
         1. (A)Separate debt instrument relating to the fixed component. The rules of § 1.1275-4(c)(4)(iii) shall apply to a contingent component the payment of which becomes fixed more than 6 months before the payment is due. For this purpose, the denomination currency of the separate debt instrument relating to the fixed payment shall be the currency in which payment is to be made and the test rate for such separate debt instrument shall be determined in the currency of that instrument. If the separate debt instrument relating to the fixed payment is denominated in nonfunctional currency, the rules of § 1.988-2(b)(2) shall apply to that instrument for the period beginning on the date the payment is fixed and ending on the payment date.
         2. (B)Contingent component. With respect to the contingent component, the issue price considered to have been paid by the issuer to the holder under § 1.1275-4(c)(4)(iii)(A) shall be translated, if necessary, into the functional currency of the issuer or holder at the spot rate on the date the payment becomes fixed.
   5. (5)Basis different from adjusted issue price. The rules of § 1.1275-4(c)(5) shall apply to an instrument subject to this paragraph (e).
   6. (6)Treatment of a holder on sale, exchange, or retirement. The rules of § 1.1275-4(c)(6) shall apply to an instrument subject to this paragraph (e).
6. (f)Rules for nonfunctional currency tax exempt obligations described in § 1.1275-4(d)
   1. (1)In general. Except as provided in paragraph (f)(2) of this section, section 1.988-6 shall not apply to a debt instrument the interest on which is excluded from gross income under section 103(a).
   2. (2)Operative rules. [Reserved]
7. (g)Effective date. This section shall apply to debt instruments issued on or after October 29, 2004.
