Nil-Paid Rights: What They Are and How They Trade

When a company issues nil-paid rights, it gives existing shareholders the free privilege to buy new shares at a fixed price (usually below market). Those who don’t want to exercise that right can sell it to someone else on a public market. The value of a nil-paid right depends on the gap between the fixed subscription price and the market price of the underlying share, and on how much time is left to exercise.

What a rights issue is

A rights issue (also called a rights offering) is a company’s way of raising capital directly from existing shareholders. Rather than issuing new shares on the open market (which dilutes existing shareholders proportionally), a company grants each shareholder the right to buy a specified number of new shares at a fixed, usually discounted, price.

For example: Apple has 16 billion shares outstanding. It announces a rights issue of 1 share for every 10 held, at £150 per share, when the market price is £180. A shareholder with 1,000 shares gets the right to buy 100 new shares at £150 each—a £3,000 investment for shares worth £18,000 at market price. That right has obvious value.

The company sets an exercise price (the price at which the right-holder can buy) and a record date (who qualifies for rights). It also sets an expiry date, typically 4–8 weeks out, after which the right disappears.

Nil-paid vs paid-up

When a company issues rights, it sometimes issues them in two forms: nil-paid and paid-up.

A nil-paid right is tradeable and costs the shareholder nothing to receive. The holder can sell it at any time before expiry, or exercise it, or let it expire worthless.

A paid-up right (sometimes called a “fully paid-up right”) usually arises after a nil-paid right is exercised, or is issued directly in some schemes. It is already “paid for” at the exercise price; the holder can exercise it immediately without further payment.

In most jurisdictions, nil-paid rights are the primary form traded; they are the instrument of choice for speculation and trading.

The value of a nil-paid right

A nil-paid right has value because the exercise price is below the market price. If the market price is £180 and the exercise price is £150, exercising the right yields an immediate £30 gain per share (before accounting for transaction costs and taxes).

But the value of the nil-paid right itself (the tradeable security) is less than that. Here’s why:

1. Time risk: The right expires in 6 weeks. If the share price falls below £150 before expiry, the right becomes worthless—you would not exercise it. The longer the time to expiry, the more time for good news to support the price, and the more the right is worth.

2. Dilution: Once the rights are exercised (especially if many shareholders exercise), the company’s equity will be diluted. New shares will be issued; earnings per share will drop slightly. The market may price this in by marking down the existing share price on the ex-rights date. The nil-paid right’s value reflects that expected dilution.

3. Share price volatility: If the share is very volatile, the right is worth more. A high-volatility share is more likely to surge above the exercise price before expiry, magnifying the gain from the right.

A rough formula for the value of a nil-paid right is:

Nil-paid right value ≈ (S − E) / (S + 1 + E / n)

where S = current share price, E = exercise price, n = number of ordinary shares you own per right (e.g., 10 if the ratio is 1 for 10). This formula accounts for dilution and time, but is simplified; real pricing also includes the time value of money and volatility.

For example: Share price £180, exercise price £150, ratio 1 for 10:

• Right value ≈ (180 − 150) / (180 + 10) ≈ 30 / 190 ≈ £0.16 per right.

If the share price shoots to £200, the right value rises to roughly (200 − 150) / (200 + 10) ≈ 50 / 210 ≈ £0.24. The right captured part of the upside.

How nil-paid rights trade

Nil-paid rights are issued as separate securities and trade on stock exchanges during the exercise window. In London, they might trade on the London Stock Exchange; in Hong Kong, on HKEX. Each nil-paid right is given a distinctive code or ticker; it is as tradeable as the underlying share.

A shareholder who receives rights but does not want to exercise them can immediately sell them at the market price. If you receive 100 nil-paid rights worth £0.16 each, you can sell them for £16 (less fees) and pocket the cash—or buy more and exercise them in bulk.

Speculators enter nil-paid rights as a leveraged bet. If you believe a share will rise substantially, buying 1,000 nil-paid rights for £160 is a cheaper way to get exposure to a 1,000-share position (which might cost £18,000) than buying the shares outright. If the share rises, the right captures some of that move. If it falls below the exercise price, you lose the £160.

Arbitrageurs also trade nil-paid rights. They might short the underlying share and buy the nil-paid right, profiting if the right-and-share combo is temporarily mispriced. Or they might buy rights when the ex-rights date is imminent, betting that late-arriving traders have not yet priced in dilution.

The mechanics of exercise

To exercise a nil-paid right, a shareholder typically:

1. Instructs their broker or the company’s registrar before the expiry date.
2. Pays the exercise price per share in full.
3. Receives the new shares, usually within 2–5 business days, in their portfolio.

Some companies allow brokers to collect the exercise price electronically; others require a manual transfer. Large institutional shareholders often exercise through their custodians.

If a shareholder does nothing by expiry, the right becomes worthless. There is no obligation to exercise; the company cannot force shareholders to buy shares at a loss. The right simply ceases to exist.

Rights issues and shareholder value

Rights issues are common in the UK, Commonwealth countries, and parts of continental Europe. They are rarer in the US, where companies more often issue shares via a registered secondary offering.

A rights issue dilutes the shareholding of anyone who does not exercise. If 20% of shareholders don’t exercise, their stake shrinks by 2% (if the rights-issue is a 10% capital increase). However, all shareholders benefit from the capital raised, which the company uses for investment, debt reduction, or other corporate purposes.

The net effect on share price depends on what the company does with the money. If it invests in high-return projects, the dilution is more than offset, and existing shareholders come out ahead. If capital is wasted, shareholders lose.

From an issuer’s perspective, a rights issue is cheaper than an underwritten secondary offering. It avoids the underwriting discount (typically 5–10%) and ensures that capital is raised only from those who believe in the company enough to exercise their rights.
