However, some debt instruments contain “original issue discount” which is a type of interest. These include debt instruments in which the maturity price exceeds the purchase price. The difference is the interest component.
Example: Asher purchases an original issue discount debt for $1,000 that matures two years later for $1,250. The difference between the maturity amount and the purchase amount, $250, is essentially interest.
Original issue discount interest is reportable as ordinary income. Such ordinary income may be realized, however, in some transactions where there was an intention to call the obligation before maturity at the time the obligation was originally issued.3 If this is the case, any gain realized in the transaction must be treated as ordinary income to the extent that the amount of gain does not exceed the sum of (a) the original issue discount, reduced by (b) the portion of original issue discount previously included in the gross income of any holder of the obligation.4
