Stock rights are short-term instruments a corporation issues to its existing shareholders, giving each one the chance to buy additional shares at a discounted price before the company offers them to anyone else. Each right is distributed pro-rata to current holdings, carries a fixed subscription price below the market price, and expires within a few weeks. If you’ve received notice of a rights offering, you generally have three choices: exercise the rights and buy the new shares, sell the rights if they’re transferable, or let them expire worthless and watch your ownership percentage shrink.
How a Rights Offering Works
The company distributes subscription rights to every common shareholder in proportion to the shares already held. Each right entitles you to buy a set number of new shares at a fixed subscription price, deliberately set below the stock’s current market price. That built-in discount is what gives the right value.
Three terms define any offering. The subscription price is what you pay per new share. The ratio tells you how many rights you need to buy one new share; a 5-for-1 ratio means five rights plus the subscription price gets you one new share. The expiration date is the hard deadline after which unexercised rights become worthless. Stock exchanges generally require shareholders to get at least 16 calendar days to act, and most offerings stay open for two to four weeks, though some run up to 60 days.
Most rights are transferable, meaning you can sell them on an exchange or over-the-counter market under a separate ticker. Non-transferable rights must either be exercised or allowed to expire. The difference matters if you don’t want to put more money into the stock: a transferable right still lets you capture some value.
Cum-Rights and Ex-Rights
When a company announces a rights offering, the stock initially trades “cum-rights,” meaning anyone who buys the stock also receives the attached rights. Once the record date passes, the stock trades “ex-rights,” and new buyers no longer receive them. On the ex-rights date, the share price typically drops to reflect that the right is no longer bundled with the share.
The theoretical ex-rights price, or TERP, estimates where the stock should trade after the rights detach. It’s a weighted average of the current market price and the lower subscription price of the new shares. If a company has 10 million shares trading at $50 and issues rights for 2 million new shares at a $40 subscription price, the TERP works out to roughly $48.33. That drop isn’t a loss for shareholders who keep their rights; the value has simply shifted from the share price into the right itself.
What One Right Is Worth
The theoretical value of a single right depends on whether the stock is still trading cum-rights or has moved ex-rights. During the cum-rights period:
Value of one right = (Market Price − Subscription Price) ÷ (Rights needed per share + 1)
If the stock trades at $50 cum-rights, the subscription price is $40, and you need five rights to buy one share, each right is worth ($50 − $40) ÷ (5 + 1) = $1.67.
Once the stock goes ex-rights, drop the “+1” because the market price has already adjusted:
Value of one right = (Ex-Rights Market Price − Subscription Price) ÷ Rights needed per share
Using the same numbers with a $48.33 ex-rights price: ($48.33 − $40) ÷ 5 = $1.67. In theory the value stays the same across the transition. In practice, market fluctuations push the traded price above or below the calculated value.
Your Three Choices
Once the rights land in your account, you have three paths.
- Exercise them. Submit the required number of rights plus the subscription price to buy new shares. Your broker or the company’s transfer agent will provide the subscription form. Payment must arrive before the expiration deadline. If your shares are tied up in transit, a notice of guaranteed delivery may protect your participation for a short window, typically about three business days past expiration.
- Sell them. If the rights are transferable, sell them on the open market just like a regular stock trade. You capture the market value without putting up more cash. This is the move when you don’t want to increase your position.
- Let them expire. Doing nothing means the rights become worthless. This is only defensible when the stock has fallen below the subscription price, making the right valueless anyway. Even then, selling a transferable right for whatever the market will pay beats letting it vanish.
The Cost of Doing Nothing
Ignoring a rights offering doesn’t just forfeit the value of the right. It shrinks your percentage ownership. When the company issues new shares and you don’t buy any, the total share count rises while your holdings stay flat. In a typical offering where a company issues 20% more shares, a shareholder who sits out sees their ownership percentage drop by roughly one-sixth. That dilution is permanent.
Fractional Rights and Oversubscription
The ratio rarely divides evenly into every shareholder’s holdings. If you own 47 shares and the ratio is 5-for-1, you’re entitled to 9.4 rights. Some companies round up, some pay cash for the fractional portion, and some pool the fractions, sell them on the open market, and distribute cash to affected shareholders. Your brokerage statement or the offering circular will say which method applies.
Many offerings also include an oversubscription privilege, which lets participating shareholders request additional shares beyond their pro-rata allotment. If other shareholders let their rights expire, the leftover shares go into a pool allocated pro-rata among those who elected to oversubscribe.
How Rights Differ From Warrants and Options
Rights, warrants, and stock options all give the holder a chance to buy shares at a set price, but they’re not interchangeable.
- Duration. Stock rights expire in weeks. Warrants last years, sometimes a decade. Exchange-traded options run from days to a couple of years for long-dated LEAPS contracts.
- Who gets them. Rights go to existing common shareholders pro-rata. Warrants are typically packaged with new debt or preferred stock as a sweetener. Options are standardized contracts traded on exchanges or granted to employees.
- Pricing. A right’s subscription price is always set below the current market price to give shareholders an incentive to participate. Warrants are usually issued at or above the current price. Exchange-traded options span strike prices above and below the market.
- Purpose. Rights raise capital from the existing shareholder base at lower cost than a public underwritten offering. Warrants make a debt or preferred issuance more attractive. Options serve hedging, speculation, or employee compensation.
Tax Rules for Stock Rights
Receiving stock rights in a standard pro-rata distribution is not a taxable event. Section 305(a) of the Internal Revenue Code provides that gross income does not include distributions of a corporation’s own stock to its shareholders.1Office of the Law Revision Counsel. 26 U.S. Code 305 – Distributions of Stock and Stock Rights The IRS and courts read this exclusion to cover stock rights distributed this way. You owe nothing when the rights arrive in your account.
The exclusion has limits. If the distribution gives some shareholders cash while increasing others’ proportionate interest, or if shareholders can choose between stock and cash, the distribution becomes taxable under Section 305(b).1Office of the Law Revision Counsel. 26 U.S. Code 305 – Distributions of Stock and Stock Rights Most straightforward rights offerings qualify for the exclusion, but offerings with unusual features deserve a closer look.
Cost Basis Allocation
When rights qualify under Section 305(a), the next question is how to assign a cost basis to them. If the fair market value of the rights at distribution is less than 15% of the fair market value of your original stock, the default basis of the rights is zero. You can elect to allocate basis between the old stock and the new rights instead, but you must make that election on the return for the year you received the rights, and it cannot be reversed.2Office of the Law Revision Counsel. 26 U.S.C. 307 – Basis of Stock and Stock Rights Acquired in Distributions
If the rights’ value is 15% or more of the stock’s value, you must allocate the original stock’s basis between the stock and the rights in proportion to their fair market values on the distribution date.2Office of the Law Revision Counsel. 26 U.S.C. 307 – Basis of Stock and Stock Rights Acquired in Distributions This reduces the basis of your original shares, which increases the gain (or decreases the loss) you’ll eventually recognize when you sell them.
Selling the Rights
When you sell stock rights, the difference between the sale proceeds and the allocated basis produces a capital gain or loss. The holding period for the rights relates back to the date you originally acquired the underlying stock, not the date you received the rights.3Office of the Law Revision Counsel. 26 U.S.C. 1223 – Holding Period of Property If you held the original stock for more than a year, any gain on the rights qualifies for long-term capital gains rates. If the rights expire unexercised, you recognize a capital loss equal to whatever basis you had allocated to them, in the year they expire.
Exercising the Rights
Exercising is not itself a taxable event, but it sets the cost basis of your new shares. That basis equals the subscription price you paid plus any basis allocated to the surrendered rights.4Office of the Law Revision Counsel. 26 U.S. Code 1012 – Basis of Property – Cost If you paid $100 and the allocated basis of your rights was $5, your new shares have a $105 basis. The holding period for these new shares starts on the exercise date, not the date you bought the original stock.3Office of the Law Revision Counsel. 26 U.S.C. 1223 – Holding Period of Property That matters if you sell the new shares within a year: the gain would be short-term even if you held the original stock for decades.
The Wash Sale Trap
One scenario catches people off guard. Suppose you sell shares of a stock at a loss and then, within 30 days, exercise rights to buy new shares of that same stock. The IRS treats the new shares as substantially identical securities, which triggers the wash sale rule and disallows your loss deduction. The disallowed loss gets added to the basis of the new shares, so it isn’t lost forever, but you can’t use it to offset gains in the current tax year. If you’re planning to harvest a tax loss on a stock that also has a rights offering pending, watch the 30-day window carefully.
Report rights transactions on IRS Form 8949 and carry the totals to Schedule D. Keep records of the original stock’s purchase date and price, the fair market values on the rights distribution date, and the subscription price paid on exercise.5Internal Revenue Service.
