Nil paid rights are short-lived, tradable entitlements a company hands to its existing shareholders during a rights issue, letting each one buy new shares at a set discount before any money changes hands. “Nil paid” means exactly that: you hold the right, but you haven’t paid the subscription price yet. The right itself has market value because of the built-in discount, and before the subscription deadline you have three choices. Pay the subscription price and take the new shares, sell the rights on the exchange for cash, or do nothing and watch them expire worthless.
What “Nil Paid” Means and Where It Comes From
A rights issue is how a publicly traded company raises fresh capital from the people who already own it. Rather than selling new stock to the public or to institutions, the company offers additional shares to current shareholders at a discount to the market price. The discount is the incentive to participate. Companies typically do this to pay down debt, fund an acquisition, or shore up the balance sheet.
The offer is structured around a ratio. A 1-for-5 rights issue means you can buy one new share for every five you already own. Hold 500 shares, receive rights to buy 100 more at the fixed subscription price. The ratio and the subscription price are set before the offering opens and don’t move.
“Nil paid” refers to the payment status of the right itself. When the rights land in your account, no cash has changed hands. You hold a voucher to buy shares at the subscription price, and until you pay that price the instrument stays nil paid. Pay it and the right converts to a fully paid share; the nil paid instrument disappears.
During the subscription window, the nil paid right trades as its own security, with its own price and its own ticker, separate from the underlying stock. Someone who doesn’t own the original shares can buy the rights on the open market, acquiring the embedded discount and the obligation to decide what to do with it before expiration. The right exists only for the length of the subscription period. There’s no federal minimum duration, but most rights offerings stay open a couple of weeks, with standby offerings sometimes running 16 to 60 days.
What One Nil Paid Right Is Worth
The starting point for valuing a nil paid right is the Theoretical Ex-Rights Price (TERP), which is where the stock should theoretically settle once the new shares are in circulation, assuming full subscription. TERP is a weighted average that blends the pre-issue share price with the lower subscription price, adjusted for the new shares entering the float.
The formula: take the market value of all existing shares, add the cash raised if every right is exercised, then divide by the total share count after the issue. Suppose a company has 10 million shares trading at $15 each and announces a 1-for-5 rights issue at $10 per share. That creates 2 million new shares and raises $20 million. TERP equals ($150 million + $20 million) รท 12 million shares, or $14.17 per share.
The theoretical value of one nil paid right is the gap between TERP and the subscription price. In the example, $14.17 minus $10.00, or $4.17 per right. That’s the theoretical profit from exercising one right and selling the resulting share at TERP.
In practice, the market price of the rights moves throughout the trading window. Movements in the underlying stock, investor sentiment, and the approaching deadline all push the price around. If the underlying rallies, the rights become more valuable. If it drops toward the subscription price, the rights lose value quickly. If the stock falls below the subscription price, the rights become effectively worthless, because anyone wanting shares can buy them cheaper on the open market.
One point worth absorbing before you decide anything: the discount is not free money. On the ex-rights date, the share price drops to reflect the dilution of new shares entering the market, and that’s what the TERP calculation captures. A shareholder who exercises ends up with more shares at a lower per-share price, but the total value of the position is roughly unchanged. Whether the deal turns out well depends on what the company does with the cash it raises.
Your Three Choices Before the Deadline
Once nil paid rights appear in your account, you have three paths, and each one has different consequences for your ownership stake, your cash, and your taxes.
Exercise the Rights
Exercising means paying the subscription price and taking the new shares. This is the move for shareholders who want to maintain their proportional ownership. If you held 2% of the company before the issue and exercise all your rights, you still hold 2% after. Your total investment grows by the subscription payment, and you avoid dilution.
Sell the Rights
You can sell the nil paid rights on the exchange during the trading window. That gives you cash reflecting the embedded discount without putting up any additional capital. Selling makes sense when you still believe in the company but don’t want to commit more money. Your ownership percentage drops, but the sale proceeds partially offset the dilution.
Liquidity tends to thin out as the deadline approaches, and bid-ask spreads widen in the final days. If you intend to sell, doing it earlier in the subscription period usually gets you a better fill.
Let the Rights Lapse
Doing nothing is the worst outcome. If the deadline passes without you exercising or selling, the rights expire worthless. No cash, no new shares, and your ownership percentage shrinks because the shareholders who did participate now hold a bigger slice. The hit to your portfolio value is real, and you get nothing in return. This is how shareholders who stop opening their brokerage statements end up losing money without a single trade.
Oversubscription and Fractional Entitlements
Many rights offerings include an oversubscription privilege, which lets you apply for additional shares beyond your basic entitlement. If other shareholders decline to exercise, the unused shares get allocated proportionally among oversubscribers based on existing holdings. It isn’t guaranteed. If demand exceeds the supply of unused rights, you may receive a partial allocation or nothing extra. The subscription price for oversubscribed shares is the same discounted rate, so it’s worth asking for if you want to grow your position.
When the rights ratio doesn’t divide evenly into your holding, you end up with a fractional entitlement. Own 17 shares in a 1-for-5 issue, and you’re entitled to 3.4 new shares. The 0.4 is the problem, since exchanges don’t trade partial shares. Companies handle this one of three ways: distribute the fractional share directly (increasingly common at brokerages that support fractional trading), round up to the nearest whole share, or aggregate the fractional pieces across all shareholders, sell them, and distribute cash proportionally. The approach is set by the board and disclosed in the offering documents.
Risks If You Buy or Hold Nil Paid Rights
Nil paid rights carry outsized risk relative to their price. The right’s value comes entirely from the gap between the market price and the subscription price, so even a modest drop in the underlying stock can cut a large percentage off the right’s value. Pay $4 for a right, watch the stock fall $2, and the right can lose half its value or more. The leverage runs both ways, but the downside is what blindsides people.
The expiration deadline adds pressure of its own. Common stock you can hold indefinitely while waiting for a recovery. Nil paid rights vanish on a fixed date. If the stock is below the subscription price at expiration, the rights are worth nothing. No extension, no recovery period, no consolation. Treat the expiration date the way an options trader does: as an absolute wall.
How Nil Paid Rights Are Taxed
When a company distributes rights to its shareholders, the distribution itself generally isn’t a taxable event. Federal tax law provides that distributions of a corporation’s own stock or stock rights to its shareholders are excluded from gross income, subject to certain exceptions involving disproportionate distributions or distributions of preferred stock.1Office of the Law Revision Counsel. 26 USC 305 – Distributions of Stock and Stock Rights
The 15% Basis Rule
Your tax basis in the rights depends on their value relative to the stock that generated them. If the fair market value of the rights at distribution is less than 15% of the fair market value of your old stock, the rights automatically take a basis of zero. You can override this by electing on your tax return to allocate a portion of your old stock’s basis to the rights, but that election is irrevocable once made.2Office of the Law Revision Counsel. 26 USC 307 – Basis of Stock and Stock Rights Acquired in Distributions
If the rights are worth 15% or more of the old stock’s value, allocation isn’t optional. You must split the basis of your old stock between the stock and the rights in proportion to their fair market values on the distribution date. That reduces your basis in the original shares and gives the rights a positive basis, which affects the gain or loss when you sell or exercise them.2Office of the Law Revision Counsel. 26 USC 307 – Basis of Stock and Stock Rights Acquired in Distributions
If You Sell the Rights
Selling the rights produces a capital gain equal to sale proceeds minus your basis in the rights. For most shareholders that basis is zero under the 15% rule, which makes the full sale price a taxable gain. The holding period of the rights is determined by how long you held the original stock, not how long you’ve held the rights. If you owned the underlying shares for more than a year before the distribution, the gain qualifies as long-term.3Office of the Law Revision Counsel. 26 USC 1223 – Holding Period of Property
If You Exercise
When you exercise, the basis of your new shares is the subscription price you paid plus whatever basis was allocated to the rights. If the rights had a zero basis, the new shares’ basis is simply the cash you paid. The holding period for the newly acquired shares starts fresh on the exercise date, regardless of how long you held the old stock or the rights.3Office of the Law Revision Counsel. 26 USC 1223 – Holding Period of Property
If You Let Them Lapse
If the rights expire unexercised and had a zero basis, there’s no capital loss to claim. Nothing was invested, so nothing is deductible. If you did elect to allocate basis to the rights under the 15% rule, a lapse may generate a recognizable loss, but how it plays out depends on your overall tax picture. The interactions here are specific enough that professional advice is worth the cost if the dollars involved are meaningful.
