Sec. 1.163-3 Deduction for discount on bond issued on or before May 27, 1969.

(1) If bonds are issued by a corporation at a discount, the net amount of such discount is deductible and should be prorated or amortized over the life of the bonds. For purposes of this section, the amortizable bond discount equals the excess of the amount payable at maturity (or, in the case of a callable bond, at the earlier call date) over the issue price of the bond (as defined in paragraph (b)(2) of section 1.1232-3).

(2) In the case of a bond issued by a corporation after December 31, 1954, as part of an investment unit consisting of an obligation and an option, the issue price of the bond is determined by allocating the amount received for the investment unit to the individual elements of the unit in the manner set forth in subdivision (ii)(a) of section 1.1232-3(b)(2). Discount with respect to bonds issued by a corporation as part of investment units consisting of obligations and options after December 31, 1954, and before Dec. 24, 1968--

should be amortized, starting with the first taxable year ending on or after Dec. 24, 1968 over the remaining life of such bonds.

Example (1). M Corporation, on January 1, 1960, the beginning of its taxable year issued for $95,000, 3 percent bonds, maturing 10 years from the date of issue, with a stated redemption price at maturity of $100,000. M Corporation should treat $5,000 ($100,000-$95,000) as the total amount to be amortized over the life of the bonds.

Example (2). Assume the same facts as example (1), except that the bonds are convertible into common stock of M Corporation. Since the issue price of the bonds includes any amount attributable to the conversion privilege, the result is the same as in example (1).

Example (3). Assume the same facts as example (1), except that the bonds are issued as part of an investment unit consisting of an obligation and an option. Assume further that the issue price of the bonds as determined under the rules of allocation set forth in subdivision (ii)(a) of section 1.1232-3(b)(2) is $94,000. Accordingly, M Corporation should treat $6,000 ($100,000-$94,000) as the total amount to be amortized over the life of the bonds.

Example (4). Assume in example (3), that prior to Dec. 24, 1968, M Corporation had only treated $5,000 as the bond discount to be amortized and deducted only $4,000 of this amount. Starting with the first taxable year ending on or after Dec. 24, 1968, M Corporation should amortize $2,000 ($6,000 discount, less $4,000 previously deducted) over the remaining life of the bonds.

Example (5). N Corporation, on January 1, 1956, for a consideration of $102,000, issued 20-year bonds in the face amount of $100,000, together with options to purchase stock of N Corporation. The issue price of the bonds as determined under the rules of allocation set forth in subdivision (ii)(a) of section 1.1232-3(b)(2) is $99,000. Until Dec. 24, 1968, N Corporation has treated as bond premium, $2,000, representing the excess of the consideration received for the bond-option investment units over the maturity value of the bonds, and has accordingly prorated and included in income $1,200 of such amount. Starting with the first taxable year beginning on or after Dec. 24, 1968, N Corporation may amortize as a deduction over the remaining life of the bonds the amount of $2,200 ($1,000 discount, plus $1,200 previously included in income).

Example (6). O Corporation, on January 1, 1956, for a consideration of $100,000, issued 20-year bonds with a $100,000 face value, together with options to purchase stock of O Corporation, which could be exercised at any time up to 5 years from the date of issue. The issue price of the bonds as determined under the rules of allocation set forth in subdivision (ii)(a) of section 1.1232-3(b)(2) is $98,000. O Corporation, upon the exercise of the options prior to Dec. 24, 1968, had deducted from income their fair market value at the time of exercise, which is assumed for purposes of this example to have been $3,000. Even though the bonds are considered to have been issued at a discount under paragraph (a)(1) of this section, O Corporation would have no deduction over the remaining life of the bonds, inasmuch as O Corporation, in computing the amount of such deduction, is required under paragraph (a)(2)(iii) of this section to reduce the amount which would otherwise be treated as bond discount, $2,000 ($100,000-$98,000), by the amount deducted from income upon the exercise of the options, in this case, $3,000.

(1) Except as provided in subparagraphs (2) and (3) of this paragraph, if bonds are issue by a corporation and are subsequently repurchased by the corporation at a price in excess of the issue price plus any amount of discount deducted prior to repurchase, or (in the case of bonds issued subsequent to Feb. 28, 1913) minus any amount of premium returned as income prior to repurchase, the excess of the purchase price over the issue price adjusted for amortized premium or discount is a deductible expense for the taxable year.

(2) In the case of a convertible bond (except a bond which the corporation, before Sept. 5, 1968, has obligated itself to repurchase at a specified price), the deduction allowable under subparagraph (1) of this paragraph may not exceed an amount equal to 1 year's interest at the rate specified in the bond, except to the extent that the corporation can demonstrate to the satisfaction of the Commissioner or his delegate that an amount in excess of 1 year's interest does not include any amount attributable to the conversion feature.

(3) No deduction shall be allowed under subparagraph (1) of this paragraph to the extent a deduction is disallowed under subparagraph (2) of this paragraph or to the extent a deduction is disallowed by section 249 (relating to limitation on deduction of bond premium on repurchase of convertible obligation) and the regulations thereunder. See paragraph (f) of section 1.249-1 for effective date limitation on section 249.
