Stock rights are short-term instruments a company issues to its existing shareholders, giving each one the option to buy additional shares at a discounted price before those shares go to the broader market. They arrive in proportion to what you already own, carry a built-in discount to the current market price, and typically expire within a few weeks. If a notice has landed in your account, the deadline is already running.
How a Rights Offering Works
In a rights offering, the company distributes subscription rights to every common shareholder in proportion to the shares they already hold. Each right entitles you to buy a set number of new shares at a fixed subscription price, set deliberately below the stock’s current market price. That discount is what makes the right worth something.
Every offering spells out the same handful of terms:
- The subscription price is the discounted price you pay per new share.
- The ratio tells you how many rights it takes to buy one new share. In a 5-for-1 offering, you surrender five rights plus the subscription price for one new share.
- The expiration date is the hard deadline. Stock exchanges generally require shareholders get at least 16 calendar days to act, and most offerings stay open for two to four weeks, though some run as long as 60 days.
Most rights are transferable, meaning you can sell them on an exchange or over-the-counter market under a separate ticker symbol. Non-transferable rights can only be exercised or allowed to expire. The distinction matters: if you can’t afford to put more money into the stock, transferable rights still let you capture some value before the deadline.
What a Right Is Worth
When a company announces a rights offering, the stock first trades “cum-rights,” meaning anyone who buys the stock also receives the attached rights. After the record date, the stock trades “ex-rights” and new buyers no longer get them. On the ex-rights date, the stock price typically drops to reflect the value that has moved from the share into the right itself.
The theoretical ex-rights price (TERP) estimates where the stock should trade after the rights detach. It’s a weighted average of the existing shares at market price and the new shares at the subscription price. If a company has 10 million shares trading at $50 and issues rights for 2 million new shares at $40, the TERP works out to roughly $48.33. For a shareholder who exercises or sells the rights, that price drop is not a loss. The value has simply moved locations.
During the cum-rights period, the theoretical value of one right is:
(Market Price − Subscription Price) ÷ (Rights needed per share + 1)
With a $50 cum-rights price, a $40 subscription price, and a 5-for-1 ratio: ($50 − $40) ÷ 6 = $1.67 per right.
Once the stock goes ex-rights, drop the “+1” because the market price has already adjusted:
(Ex-Rights Market Price − Subscription Price) ÷ Rights needed per share
Using an ex-rights price of $48.33: ($48.33 − $40) ÷ 5 = $1.67. In theory the value holds steady across the transition. In practice, rights trade above or below the calculated value as the market moves.
Your Three Choices
Once rights hit 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 provides the subscription form. Payment must arrive before the expiration deadline. If shares are in transit, a notice of guaranteed delivery may protect your right to participate for a short period, typically about three business days past expiration, while the shares are delivered.
- Sell them. If the rights are transferable, sell them on the open market like any other security. You capture the right’s market value without putting up additional cash. This is the move when you don’t want to increase your position.
- Let them expire. Doing nothing turns the rights into zero. This is only neutral if the stock has already fallen below the subscription price, which makes 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 right’s value. It shrinks your percentage ownership. When the company issues new shares and you buy none, the 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, and that dilution is permanent. If you still believe in the company, either exercising or selling and reinvesting the proceeds elsewhere beats inaction.
Fractional Rights
The ratio rarely divides evenly into every shareholder’s position. Own 47 shares in a 5-for-1 offering and you’re entitled to 9.4 rights. Companies handle the leftover differently: some round up, some pay cash in lieu of the fractional portion, and some aggregate all fractional rights, sell them on the open market, and distribute the cash to affected shareholders. Your brokerage statement or the offering circular will tell you which method applies.
Oversubscription
Many offerings include an oversubscription privilege, which lets participating shareholders request additional shares beyond their pro-rata allotment. When other shareholders let rights expire or sell them, the unsubscribed shares go into a pool, and shareholders who elected to oversubscribe get a crack at those leftovers, typically allocated on a pro-rata basis relative to the extra shares each person requested. If you want to grow your stake, check the subscription form for this option.
How Rights Differ From Warrants and Options
Rights, warrants, and options all give the holder a way to buy shares at a set price, but they aren’t interchangeable.
- Duration. Stock rights expire in weeks. Warrants last years, sometimes a decade. Exchange-traded options range 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 often packaged with new debt or preferred stock as a sweetener. Options are standardized contracts traded on exchanges or granted to employees as compensation.
- Pricing. A right’s subscription price is always below the current market price, since the purpose is to pull shareholders in. Warrants are typically issued at or above the current price, betting on future appreciation. Exchange-traded options span strike prices above and below the market.
- Purpose. Rights raise capital from the existing shareholder base at lower cost than an underwritten public offering. Warrants make a debt or preferred stock offering more attractive. Options serve hedging, speculation, or employee retention.
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 excludes distributions of a corporation’s own stock to its shareholders from gross income.1Office of the Law Revision Counsel. 26 U.S. Code 305 – Distributions of Stock and Stock Rights The IRS reads this to cover stock rights distributed in this manner, so you owe nothing when they arrive.
That exclusion has limits. If the distribution gives some shareholders cash while increasing other shareholders’ proportionate interest, or lets shareholders choose between stock and cash, it 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 in the Rights
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 instead to allocate basis between the old stock and the new rights, but you must make that election on the tax return for the year you received the rights, and it can’t 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 your original stock’s basis between the stock and the rights in proportion to their respective 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 That allocation reduces the basis of your original shares, which increases the gain (or shrinks the loss) you’ll recognize when you eventually sell them.
Selling or Exercising
When you sell rights, the difference between the sale proceeds and the allocated basis is a capital gain or loss. The holding period relates back to the date you originally acquired the underlying stock, not the date the rights arrived.3Office of the Law Revision Counsel. 26 U.S.C. 1223 – Holding Period of Property If you held the original stock more than a year, any gain on the sale of the rights qualifies for long-term rates. If the rights expire unexercised, you recognize a capital loss equal to whatever basis you allocated to them, in the year they expire.
Exercising rights is not itself a taxable event, but it sets the cost basis of the 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 Pay $100 with $5 of allocated basis on the rights, and the new shares have a $105 basis. The holding period for the 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 those new shares within a year of exercising, because the gain is short-term even if you held the original stock for decades.
Watch the Wash Sale Rule
One scenario catches people off guard. Sell shares of a stock at a loss, then within 30 days exercise rights to buy new shares of the same stock, and the IRS treats the new shares as substantially identical securities. The wash sale rule disallows the loss deduction. The disallowed loss gets added to the basis of the new shares, so it isn’t gone forever, but you can’t use it to offset gains in the current tax year. If you’re planning to harvest a loss on a stock with a pending rights offering, 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 distribution date, and the subscription price paid on exercise.5Internal Revenue Service. Instructions for Form 8949 – Sales and Other Dispositions of Capital Assets Those records are the only way to reconstruct basis if the IRS asks questions years later.
