spin-offs, mergers, and what happens to your shares

In short

A friend of mine once opened his brokerage statement and found a stock he never bought. He thought it was a mistake. It was a spin off, and it was legitimate. If you own shares in a company that splits itself in two, you will usually end up holding shares in both pieces. In a merger, your old shares may turn into cash, new shares, or a mix of the two. The company will send you a notice that explains your choice, and it pays to read it. Your broker will track your cost basis, but the number can need checking. Taxes depend on how the deal is built, so look for the words tax free or taxable in the notice.

The whole of it

What it is

I once watched a neighbor take apart an old clock on his porch, and he laid every gear out on a towel. That is a decent picture of a spin off. A company takes one of its businesses, sets it up as its own separate company, and hands out shares of the new company to the people who already own the old one. The parent company keeps going. A brand new company is born. You end up holding both.

A merger works the other way around. Two companies join together. In an acquisition, one company buys another. The buyer might pay in cash, in its own shares, or in some of each. If the company you own is the one being bought, your shares go away, and something else takes their place.

You have probably wondered what you actually get out of these deals. Here is the plain answer. You get whatever the deal paperwork says you get, and not a penny more or less. The paperwork is public, and it is written for people like you.

Think of it this way. Your ownership has a total value before the deal. After the deal, that value gets sliced up or swapped. Nothing magic happens to it. Splitting a pie does not make the pie bigger.

How it works

If you are holding shares in a company that plans a spin off, the board of directors first announces it. The company sets a record date. If you own the shares on that date, you qualify. Then comes a distribution date, which is the day the new shares land in your account.

The ratio matters a great deal. A company might say it will give one new share for every four old shares. If you own 100 shares, you divide 100 by 4 and get 25 new shares. What if you own 102 shares? Then 102 divided by 4 is 25.5. The half share is usually paid out in cash instead, which is called cash in lieu of a fractional share.

A neighbor of mine once told me a merger is just a swap with more paperwork, and he had a point. In a stock deal, the buyer offers a set number of its own shares for each of yours. In a cash deal, the buyer pays a set price per share, and your shares are cashed out. Some deals are a blend. You may even get a choice between the two, with a deadline. Miss the deadline and the plan picks for you.

The company files its plans with the Securities and Exchange Commission. A spin off may use a registration document called Form 10, though the company could choose another SEC form. Mergers often use a proxy statement or Form S-4. These are free to read on the SEC website, at sec.gov, through a tool called EDGAR. The language is heavy, but the summary pages near the front are kinder than you might fear.

Shareholders may get a vote on a merger. A proxy statement is the packet that asks for your vote. Your vote counts in proportion to your shares. Reading it takes an evening. Voting takes a minute.

The numbers, and where to find yours

Let me be honest about something. The numbers that matter most to you are the ones in your own account, and nobody can guess them from a distance. Your cost basis is what you paid for your shares, and it sets your gain or loss later. After a spin off, that basis is usually split between the old shares and the new ones. The company will publish how it splits, often as a percent for each. Your broker applies it.

Look for the company's tax notice. It often appears on the investor relations page of the company website. The Internal Revenue Service also sends everyone to Form 8937, which companies file to describe how a deal changes basis. Companies post it publicly.

Your broker reports the sale of shares on Form 1099 B. Basis after a corporate action can be hard to record, so it helps to compare the broker figure with the company notice. The IRS explains how stock basis works in Publication 550, titled Investment Income and Expenses. It also covers the tax rules for dividends and sales.

If a cash payment comes with the deal, whether for a fractional share or a full buyout, it may be taxable. The holding period matters too. The rule for the long term capital gains rate depends on how long you held the shares, and the IRS sets that rule. The tax rate brackets change by year, so look them up as the current figure, which the official source publishes each year. The IRS also publishes the holding period that qualifies for the lower rate, at the current figure, which the official source publishes each year.

A worked example

Let me tell you about a retired mail carrier named Dorothy Wilkins. She owned 200 shares of a company called Harbor Foods. She had paid $40 a share, so her total cost was 200 shares times $40, which is $8,000.

Harbor Foods announced a spin off of its snack division. The plan gave one new share for every five old shares. So Dorothy took 200 divided by 5 and got 40 new snack shares. Her old shares stayed put.

The company's tax notice said 85 percent of the old basis stayed with Harbor Foods and 15 percent moved to the new snack company. Dorothy did the math slowly, with her coffee. The old shares kept 85 percent of $8,000, which is $6,800. The new shares took 15 percent of $8,000, which is $1,200. Add them together and you get $8,000 again. That check matters.

Her per share basis came out like this. For Harbor Foods, $6,800 divided by 200 shares is $34 a share. For the snack company, $1,200 divided by 40 shares is $30 a share. Notice that she paid nothing extra. Her original cost simply got divided up.

Some months later, the snack company was bought. The buyer paid $38 a share in cash. Dorothy's 40 shares brought in 40 times $38, which is $1,520. Her basis was $1,200. So her gain was $1,520 minus $1,200, which is $320. Because she had held the original shares for years, the holding period carried over.

She checked her broker statement against the company notice. They matched. Good news for Dorothy.

Where it goes wrong

I have seen smart people trip on this, and I have tripped myself. Basis is the first trap. A broker may leave the old basis on the old shares and show nothing for the new ones. Then a sale looks like pure gain, and the tax bill looks bigger than it should. Check it.

Missed deadlines are the second trap. In a deal that offers a choice between cash and stock, a missed date means the default applies. Read the notice early.

Fractional shares trip people up as well. The cash paid for a fraction is a sale, and it can be taxed even when the rest of the deal is not. The amount is often small, but it still shows up on the tax form.

Scam notices are the fourth trap. When a deal makes news, fake letters and calls follow. A real company or its transfer agent will never demand payment to give you your new shares. If something feels off, contact the company or your broker directly, using a number you found yourself.

Last, there is the assumption that every deal is tax free. Many spin offs and stock mergers are built to be tax free, but not all of them are. A deal with cash in it may be taxed in part. The company notice says which one applies. Trust the notice over any rumor.

Questions to answer before you leave this page

Which date does the company set as the record date for owning the shares, and does the date on your own statement match it? Does your broker show a basis for both the old and the new shares, and do the two add up to what you originally paid? Is the deal in your notice described as tax free, taxable, or a mix, and where did you read that? If there is a cash and stock choice, what is the deadline, and what happens if you miss it? Have you found the Form 8937 or the tax notice on the company website? And if a letter or call about the deal asks you for money, who will you phone to confirm it is real?
