amount includible as original issue discount for each accrual period by (i) calculating the amount of original issue discount allocable to each accrual period in the foreign currency using the constant yield method described above and
(ii) translating that foreign currency amount at the average spot exchange rate in effect during that accrual period (or, with respect to an interest accrual period that spans two taxable years, at the average spot exchange rate for each
partial period). Alternatively, you may translate the foreign currency amount at the spot exchange rate on the last day of the accrual period (or the last day of the taxable year, for an accrual period that spans two taxable years) or at the spot
exchange rate on the date of receipt, if that date is within five business days of the last day of the accrual period, provided that you have made the special election described above under “— Payments or Accruals of Interest.”
Because exchange rates may fluctuate, if you are the holder of an Original Issue Discount Debt Security that is also a foreign currency debt security, you may recognize a different amount of original issue discount income in each accrual period than
would be the case if you were the holder of an otherwise similar Original Issue Discount Debt Security denominated in U.S. dollars. Upon the receipt of an amount attributable to original issue discount (whether in connection with a payment of an
amount that is not qualified stated interest or the sale or retirement of the Original Issue Discount Debt Security), you will recognize ordinary income or loss measured by the difference between the amount received (translated into U.S. dollars at
the spot exchange rate in effect on the date of receipt or on the date of disposition of the Original Issue Discount Debt Security, as the case may be) and the amount accrued (using the spot exchange rate applicable to such previous accrual).

If you purchase an Original Issue Discount Debt Security outside of the initial offering at a cost less than its remaining redemption amount
(i.e., the total of all future payments to be made on the debt security other than payments of qualified stated interest), or if you purchase an Original Issue Discount Debt Security in the initial offering at a price other than the debt
security’s issue price, you generally will be required to include in gross income the daily portions of original issue discount, calculated as described above. However, if you acquire an Original Issue Discount Debt Security at a price greater
than its adjusted issue price, but less than its remaining redemption amount, you will be required to reduce your periodic in
