What it means
A traditional corporate bond owes its coupon on schedule, and missing a payment is a default. An income bond changes that deal: the coupon is owed only if the issuer earns enough, as defined in the bond's terms.
For the issuer, this is breathing room. A company with shaky solvency can raise capital without committing to fixed interest it may not be able to pay in a bad year.
For the investor, the risk is obvious. The principal is promised back at maturity, but the income stream is conditional, so buyers demand a much higher rate than on ordinary bonds to compensate.
The closest cousin is the preferred share, which also pays only when declared. The difference is that missed preferred dividends usually accumulate and must be caught up later, while missed income bond interest typically does not, unless the terms say otherwise.
Income bonds show up most often in restructurings. A company in or emerging from Chapter 11 may issue them, in that context often called adjustment bonds, to replace debt it could not service.
A common restructuring term requires interest only in years with positive earnings. If the year is negative, no coupon is due and no default occurs.
These instruments are rare. They exist to solve a specific problem: keeping a strained company funded and operating while creditors wait for better years.
For an investor, the analysis is less about the coupon and more about survival. The real question is whether the issuer's future earnings can service the debt at all, which is credit analysis of a distressed business, not a yield comparison.
In practice
Real-world examples.
Example
A retailer emerging from Chapter 11 issues adjustment bonds to its old creditors in place of debt it could not service. Interest is owed only in profitable years while the chain rebuilds its stores and supplier relationships. Creditors accept the conditional coupon because the alternative may be liquidation.
Example
A manufacturer with volatile earnings raises $20,000,000 through income bonds rather than bank debt. In a loss year it owes no coupon and avoids default, which protects it from lenders demanding immediate repayment. In a strong year it pays the full interest out of earnings.
Example
A bondholder reviews an income bond that skipped its coupon last year. Because the issuer reported a loss, the skip was permitted by the bond's terms and is not a default event. She notes that the missed interest does not accumulate, so she checks current earnings before deciding whether to hold.
Formula
Calculation
A simple illustration: an income bond has a face value of $1,000 and a stated coupon of 9%, payable only in years with positive earnings.
In a profitable year the holder receives $90 per bond ($1,000 x 9%). In a loss year the holder receives $0 and the issuer is not in default.
Over five years with three profitable years, the holder collects $270 of interest (3 x $90) plus the $1,000 face value at maturity, a total of $1,270, assuming the issuer survives. That survival assumption is the real risk being priced, which is why the stated 9% sits far above rates on sound issuers.
For comparison, a conventional bond with the same 9% coupon would have paid $450 over the same five years (5 x $90). The income bond holder therefore receives $180 less in this scenario ($450 - $270), which is the price of the flexibility the issuer was given.Case study
Seen in the real world.
The following is an illustrative and fictional case. Meridian Rail, a fictional regional freight company, emerged from a debt restructuring with its tracks and contracts intact but its credibility spent. Banks would not lend to it at tolerable rates. As part of the reorganisation plan, it issued adjustment bonds to former creditors, promising repayment of face value in ten years with interest owed only in profitable years. The first two years were lean, and no coupons were paid.
Bondholders grumbled but had no default to declare, because the terms had always said interest followed earnings. In the third year freight volumes recovered and the company posted a profit. Coupons were paid in full that year, and the bonds, once deeply distrusted, began trading closer to their face value. Meridian eventually refinanced the bonds away. The income bond structure had done its narrow job: it kept the company alive through years when a fixed coupon would have finished it.
The lesson for investors in this invented story lies in how the risk was priced. Those who bought at a steep discount during the lean years collected both the later coupons and the price recovery, while those who had expected a guaranteed coupon were disappointed. No outcome is implied for any real bond.
Watch out
Common mistakes.
- Treating the coupon as guaranteed. Interest on an income bond is conditional on earnings, and a skipped coupon is usually not a default.
- Comparing its yield to normal bonds without context. The high stated rate prices the risk that little or no interest is ever paid.
- Assuming missed interest accumulates. Unlike cumulative preferred dividends, unpaid income bond coupons typically do not pile up for later.
Questions
People also ask.
Is the principal guaranteed?
The face value is promised at maturity, but if the issuer fails entirely, recovery depends on the bankruptcy process like any other creditor claim.
What is an adjustment bond?
An income bond issued in a corporate reorganization, typically paying interest only in years with positive earnings.
Who buys income bonds?
Investors comfortable with distressed credit who judge the issuer will survive and earn enough to pay, in exchange for a high stated rate.
