Fully Diluted Shares: Treasury Stock Method

From M&I Equity vs Enterprise Value Question 6: "Let's say a company has 100 shares outstanding, at a share price of $10 each. It also has 10 options outstanding at an exercise price of $5 each - what is its fully diluted equity value?

The answer basically says that we take $1000 from the current basic shares. But then it says that when the options are executed, 10 additional shares go to the company so that it has 110 shares outstanding. This confuses me, as I thought that if the company is exercising the options, the company is essentially buying its 10 options at a lower price (giving shareholders $50, which are subsequently reinvested). But then wouldn't that reduce "shares outstanding" by 10 since "shares outstanding" refers to what shareholders, not the company, has of shares? Or are we assuming that these shares outstanding are treasury stock? Thank you in advance.

The key mistake you're making is thinking that that the options are being exercised by the company. This is not the case; they're owned and being exercised by employees. A company itself doesn't hold its own options and exercise them. When the options are exercised, the 10 additional shares aren't going to the company; they're going to the employees who exercised them. The company receives $50 from that event and uses that $50 to buy back as many shares as it can, which is 5 in this case. That's why the final diluted share count is 105 (100+10-5)

 

You say that the company would receive 50 dollars, which means that the shareholders must be buying options. This makes sense: the shareholders would want to buy options when cheaper than market price/“in the money” I think was the terminology I found on the web.
 

So is this the process: the investors buy 10 options, so there are 110 shares outstanding, then the company buys back 5 shares of stock from the shareholders using its newfound cash for 105 outstanding). (Whereupon I am admittedly confused why the company just decides to buy back shares). Thanks for the patience.

Buying options is not the same thing as exercising options, and it's not the only way to get options. You're confusing options activity in the market with stock-based compensation. There need not be investors directly involved here. It's all about employees.

When employees receive stock-based compensation in the form of options, they aren't buying it. (When we talk about options in the context of share dilution, we're only talking about call options) A call option is just an agreement between a buyer (employee in this case, who doesn't actually spend money to buy the option) and the seller (the company, who isn't actually selling anything but is instead using the option as a means of compensation for labor): up until a certain expiration date set by the seller, the buyer can purchase a share of the company at $X price. $X is the exercise price, or strike price. If the company's shares are worth over $X in the market, the employee can exercise the option to buy a share at $X price and make an instant profit that is equal to the difference between $X and the current market price of the company.

So this is the process that is required by GAAP for companies to calculate fully diluted share count for calculating diluted EPS

  • Company has 100 share outstanding
  • Employee does something for the company and receives 10 stock options as part of their compensation
  • Stock price is already high enough that those options are in-the-money (i.e., exercise price is below the market price for a call option)
  • From here on, to calculate fully diluted share count, we don't actually care about what has happened, but will happen. The employees have yet to exercise or sell (not the same "selling" as earlier, they're just swapping someone else as the "buyer" in the agreement) their options, but people don't usually just let their options expire for no reason and leave money on the table. Therefore, we assume that the options will end up being exercised one way or another. Exercising these options means that the employees give $50 to the company and receive 10 shares. There we go, share count is 110 for now
  • This is where we make another key assumption. GAAP assumes the company buys back as many shares as possible with the cash from people exercising the options. So to minimize share dilution, the company buys 5 shares back from shareholders in the market from that $50 cash. Now we have 105 fully diluted shares outstanding
