method based on daily compounding. If you are not required, and do not elect, to include discount in income currently, any gain you realize on the sale, exchange, retirement or other taxable disposition of a short-term debt security will generally be ordinary income to you to the extent of the discount accrued by you through the date of the sale, exchange, retirement or other taxable disposition. In addition, if you do not elect to currently include accrued discount in income, you may be required to defer deductions for a portion of your interest expense with respect to any indebtedness incurred or continued to acquire or carry the short-term debt securities.
Market Discount
If you purchase a debt security for an amount that is less than its stated redemption price at maturity (or, in the case of an original issue discount debt security, its adjusted issue price), the amount of the difference will be treated as “market discount” for United States federal income tax purposes, unless that difference is less than a specified de minimis amount. Under the market discount rules, you will be required to treat any principal payment on, or any gain on the sale, exchange, retirement or other taxable disposition of, a debt security as ordinary income to the extent of the market discount that you have not previously included in income and are treated as having accrued on the debt security at the time of the payment or disposition (as described below).
In addition, you may be required to defer, until the maturity of the debt security or its earlier disposition in a taxable transaction, the deduction of all or a portion of the interest expense on any indebtedness incurred or continued to acquire or carry the debt security. You may elect, on a security-by-security basis, to deduct the deferred interest expense in a tax year prior to the year of disposition. You should consult your own tax advisors before making this election.
Any market discount will be considered to accrue ratably during the period from the date of acquisition to the maturity date of the debt security, unless you elect to accrue on a constant interest method. You may elect to include market discount in income currently as it accrues, on either a ratable or constant interest method, in which case the rule described above regarding deferral of interest deductions will not apply. An election to accrue market discount on a current basis will apply to all debt instruments acquired with market discount that you acquire on or after the first day of the first taxable year to which the election applies. The election may not be revoked without the consent of the Internal Revenue Service (the “IRS”).
Acquisition Premium, Amortizable Bond Premium
If you purchase an original issue discount debt security for an amount that is greater than its adjusted issue price but equal to or less than the sum of all amounts payable on the debt security after the purchase date other than payments of qualified stated interest, you will be considered to have purchased that debt security at an “acquisition premium.” Under the acquisition premium rules, the amount of OID that you must include in gross income with respect to the debt security for any taxable year will be reduced by the portion of the acquisition premium properly allocable to that year.
If you purchase a debt security (including an original issue discount debt security) for an amount in excess of the sum of all amounts payable on the debt security after the purchase date other than payments of qualified stated interest, you will be considered to have purchased the debt security at a “premium” and, if it is an original issue discount debt security, you will not be required to include any OID in income. You generally may elect to amortize the premium over the remaining term of the debt security on a constant yield method as an offset to interest when includible in income under your regular accounting method. Special rules limit the amortization of premium in the case of convertible debt instruments. If you do not elect to amortize bond premium, that premium will decrease the gain or increase the loss you would otherwise recognize on retirement or other disposition of the debt security.
Sale, Exchange and Retirement of Debt Securities
Upon the sale, exchange, retirement or other taxable disposition of a debt security, you will recognize gain or loss equal to the difference between the amount you realize upon the sale, exchange, retirement or other
