Cash Equities

Rights Issue

Also known as: Subscription right, Nil-paid rights, Bezugsrecht

A short-dated option handed to every shareholder for free — and the one corporate action where doing nothing is the only guaranteed way to lose money.

1 · SnapshotThe one idea to remember
Key intuition: a rights issue hands you a short-dated in-the-money option for free. Exercise it, sell it, or lose it — but never ignore it, because the third option is the only one that destroys value with certainty.
2 · BeginnerWhat is it, really?

When a listed company needs new equity, one route is to offer it to existing shareholders first, at a discount, in proportion to what they already own. That entitlement is a right, and it has real value.

A typical structure: 1 new share for every 4 held, at €8 when the shares trade at €12. Every shareholder gets rights they can use in one of three ways:

  • Subscribe — pay €8 per new share, keep the same percentage of the company.
  • Sell the rights — they trade on-exchange during the offer period; take the cash, accept dilution.
  • Do nothing — and this is the trap. Unexercised rights usually expire worthless, which means giving away something with a real market price for nothing.

The share price falls when the rights start trading, and this alarms people who should not be alarmed: the fall is arithmetic, not bad news. Value moved out of the share and into the right, and shareholders hold both.

3 · IntermediateHow it works in practice

The arithmetic: TERP

The theoretical ex-rights price is the weighted average of old and new shares:

$$ \text{TERP} = \frac{N_{\text{old}} \cdot P_{\text{cum}} + N_{\text{new}} \cdot P_{\text{sub}}}{N_{\text{old}} + N_{\text{new}}} \qquad \text{Right value} = \frac{\text{TERP} - P_{\text{sub}}}{\text{rights per new share}} $$

With 1-for-4 at €8 against a €12 price: TERP = (4 × 12 + 1 × 8) / 5 = €11.20. Each right is worth (11.20 − 8) / 4 = €0.80. A holder of 400 shares sees the price drop €0.80 and holds 400 rights worth €0.80 each — exactly neutral.

Pre-emption rights are a legal entitlement in much of Europe and a matter of custom elsewhere — one reason rights issues dominate European recapitalisations while US companies more often place shares directly.

Worked example: a deeply discounted 3-for-1 at €2 against a €10 price gives TERP = (1 × 10 + 3 × 2) / 4 = €4. The 60% "price collapse" on the ex-date is pure arithmetic. Financial media reliably reports it as a crash, and the discount's size signals urgency rather than value.
4 · AdvancedPricing & valuation

The right as an option, priced properly

A nil-paid right is a call on the share, struck at the subscription price, expiring at the end of the offer period. It trades above intrinsic value by a time premium the Black–Scholes pricer will quantify — small, because the period is two to three weeks, but real, and larger the more volatile and the closer to the strike:

$$ V_{\text{right}} \;=\; \frac{1}{n}\,C_{BS}\!\left(S, K = P_{\text{sub}}, T = T_{\text{offer}}, \sigma\right) $$
  • Rights are leveraged: at €0.80 against an €11.20 share, a 5% share move is a 70% move in the right. This makes them a favourite of short-term traders and a genuine hazard for holders who buy them without understanding the gearing.
  • Rights arbitrage is a standard desk trade — buy nil-paid rights, short the shares against the delta, exercise at expiry. It is one of the mechanisms that keeps rights priced close to theoretical value.

The underwriting layer

Most rights issues are underwritten: banks guarantee the proceeds and take the unsubscribed shares. This produces a specific dynamic worth understanding:

  • Fees run to 2–4% of gross proceeds — expensive, and a live subject of governance criticism.
  • A deeper discount makes the issue more certain to be taken up and the underwriting less risky. Underwriters therefore push for discounts, and the discount is not primarily a valuation signal.
  • Rump shares — those not taken up — are placed in the market afterwards, and the proceeds above the subscription price are usually returned to the non-participating holders in developed markets. This partially rescues shareholders who ignored the whole thing, which is a mitigation and not a plan.

What a rights issue actually tells you

The information content is in the use of proceeds, not the discount. Equity raised to fund an identified investment is a different event from equity raised to repair a balance sheet, and the market prices them very differently. A deeply discounted rescue rights issue from a leveraged company is one of the clearest signals available that lenders have stopped extending credit — the pattern behind the 2008 bank recapitalisations.

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.

5 · Desk notesHow practitioners think about it
Practitioner note: the immediate task is mechanical — decide before the deadline, and never let rights lapse. The analytical task is separate: read the use of proceeds and ask whether this is a company investing or a company patching.
