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.

Debt securities that provide for interest at variable rates (“Variable Interest Rate Debt Securities”) generally will either bear interest at a “qualified floating rate”, or they will bear interest at an “objective rate” and thus may be treated as “variable rate debt instruments” under Treasury regulations governing accrual of OID. A Variable Interest Rate Debt Security will qualify as a “variable rate debt instrument” if (a) its issue price does not exceed the total noncontingent principal payments due under the Variable Interest Rate Debt Security by more than a specified de minimis amount, (b) it provides for stated interest, paid or compounded at least annually, at (i) one or more qualified floating rates
