Question juridique clé
Whether the issuance discount on the option bond was taxable as investment income at redemption.
Solution extraite
Yes. The option part and bond part must be treated separately; the issuance discount attributable to the bond part is taxable investment income upon redemption under the rule for interest from assets.
Motifs extraits
An option bond is not a discount bond. The discount compensates for the low coupon and is economically the price of the warrant. Since the bond part is not an obligation with predominantly one-time interest, the discount is taxed at redemption under the ordinary interest provision.
