Meaning
A debt instrument carries a difference between its face value at maturity and its lower initial price. Financial markets use original issue discount to provide investors with a return that functions like interest and compensation for the time value of money. This discount accounts for the risk of the loan.
Tax Treatment
The internal revenue service requires the holder of the bond to recognize a portion of the discount as income every year. Even though no cash interest is paid, the original issue discount must be reported as taxable interest on an accrual basis. This creates a phantom income situation where the investor pays taxes on money not yet received.
The issuer conversely takes a deduction for the same amount. This tax treatment prevents the deferral of liability on long term debt instruments.
Yield Calculation
Investors determine the effective interest rate by spreading the discount over the life of the security using a constant yield method. Because the original issue discount represents a fixed gain, it provides a predictable return relative to the purchase price. This calculation is vital for comparing the bond to other interest bearing assets.
Debt Issuance
Companies with limited cash flow may prefer to issue zero coupon bonds to preserve capital during the growth phase. By utilizing original issue discount, the firm avoids the need for periodic interest payments while still attracting lenders. This strategy shifts the entire cash outflow to the maturity date.
It is a common tool in high yield or distressed debt markets.
