 “Market Discount Debt Security”) if the debt security’s stated redemption price at maturity or, in the case of a Discount Debt Security, the debt security’s “revised issue price”, exceeds the amount for which the U.S. Holder purchased the debt security by at least 0.25% of the debt security’s stated redemption price at maturity or revised issue price, respectively, multiplied by the number of remaining complete years to the debt security’s maturity (or, in the case of a debt security that is an installment obligation, possibly multiplied by the debt security’s weighted average maturity). If this excess is not sufficient to cause the debt security to be a Market Discount Debt Security, then the excess constitutes “de minimis market discount”. For this purpose, the “revised issue price” of a debt security generally equals its issue price, increased by the amount of any OID that has accrued on the debt security and decreased by the amount of any payments previously made on the debt security that were not qualified stated interest payments.

Any gain recognized on the sale or retirement of a Market Discount Debt Security (including any payment on a Market Discount Debt Security that is not qualified stated interest) generally will be treated as ordinary income to the extent of the accrued market discount on the Market Discount Debt Security. Alternatively, a U.S. Holder of a Market Discount Debt Security may avoid such treatment by electing to include market discount in income currently over the life of the Market Discount Debt Security. This election will apply to all debt instruments with market discount acquired by the electing U.S. Holder on or after the first day of the first taxable year to which the election is made. This election may not be revoked without the consent of the IRS. A U.S. Holder of a Market Discount Debt Security that does not elect to include market discount in income currently will generally be required to defer deductions for interest on borrowings incurred to purchase or carry a Market Discount Debt Security. Such interest is deductible when paid or incurred to the extent of income from the debt security for the year. If the interest expense exceeds such income, such excess is currently deductible only to the extent that such excess exceeds the portion of the market discount allocable to the days during the taxable year on which such debt security was held by the U.S. Holder.
