Kernrechtsfrage
Whether the issuance discount on the option bond was taxable as investment income at redemption.
Extrahierter Entscheid
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.
Extrahierte Begründung
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.
