Hybrid capital issue

Companies raise money in two ways: they borrow it, or they sell shares. Borrowing is cheaper but adds debt; selling shares does not add debt but dilutes the owners.

A hybrid tries to sit between the two. It is legally a bond — it pays a coupon and has a face value — but it is written with features that make it behave partly like equity: it never matures, or matures very far away; the company can stop paying the coupon without defaulting; and if the company fails, the holders are paid almost last.

Why bother? Because rating agencies will treat part of it as capital rather than as debt. That means the company can raise money without its credit rating deteriorating as much as an ordinary bond would cause.

The strange part is the call date. These bonds usually have a date, five or ten years out, on which the company may repay them but is not obliged to. Almost everybody prices them as if that date were the maturity, because almost every issuer calls. Almost.

The three features that earn equity credit

• Permanence — no maturity, or one so distant it is effectively none. A call date is permitted, and there are limits on how the issuer may signal it will call.
• Loss absorption — deep subordination, so the instrument absorbs losses before senior creditors do.
• Coupon flexibility — the ability to skip a payment without triggering a default. Whether skipped coupons accumulate matters enormously to the holder and to the equity credit.

Agencies grade these features and award a proportion of equity treatment. The structure is designed backwards from the treatment sought.

The call, and the step-up

Most hybrids carry a coupon that resets at the call date, often to a benchmark plus the original spread, sometimes with a modest increase. That reset is designed to make calling economically sensible without making it a legal obligation — because an obligation would defeat the permanence the equity credit requires.

An issuer that does not call is behaving lawfully and is read as signalling that it cannot refinance cheaply. Non-calls therefore happen rarely and move the whole sector's spreads when they do.

Bank hybrids are a different animal

For banks, the equivalent instrument is regulatory capital, and its terms are set by supervisors rather than by agencies. Additional Tier 1 instruments can be written down or converted into shares when a capital ratio falls below a trigger — a contractual loss absorption that happens while the bank is still operating. See the contingent convertible on the markets side.

Who buys them

Investors reaching for yield within an issuer they already know and are comfortable with. The credit is the same company; the position in the queue is much worse. That trade — same borrower, worse rank, more yield — is the whole proposition.

The extension risk nobody prices until it happens

If a hybrid is priced to a call five years out and the issuer does not call, the instrument's duration changes overnight from five years to something much longer. Prices fall sharply — not because the credit deteriorated but because the assumed maturity moved.

This is a clean example of a risk that is contractual, disclosed, understood by everybody and priced at almost nothing until it materialises. It is the closest thing on this desk to a short volatility position in bond clothing.

The accounting question is separate from the rating question

Whether an instrument is equity or a liability in the accounts follows accounting standards, and can differ from the rating agencies' treatment and from the tax treatment. It is entirely possible for one instrument to be equity for accounting, half equity for the rating and debt for tax — and the tax deductibility of the coupon is frequently a large part of why it was issued at all.

Which means three answers to "is this debt or equity?", all correct, all in different documents.

Deferral, and what it is worth

The right to skip a coupon sounds valuable to the issuer and is used almost never, because the signal it sends is devastating. Most structures also make deferral cumulative, and block dividends to shareholders while any coupon is unpaid — which converts a theoretical flexibility into something close to an obligation. That is deliberate: an option that would actually be used would not be worth much equity credit.

Where it sits in the structure

Just above ordinary shares and below everything else. In a restructuring this is nearly always below the value break, which means hybrid holders are negotiating for option value rather than for recovery — see restructuring. Investors know this; the extra yield is the price of that position.

The formulas above are standard textbook formulations, simplified for teaching. They explain the mechanism — they are not a valuation tool, and they will not reproduce a dealer’s price.
