What is a Stock Option Expense?

A stock option expense refers to the cost incurred by a company when it grants stock options to its employees. This expense is recognized in the financial statements and is crucial for understanding the overall compensation costs associated with employee stock options.

How to Calculate Stock Option Expense?

The stock option expense can be calculated using the following formula:

Total Expense (E) is given by:

§§ E = (M - X) * N * (1 - T) * e^{-rT} §§

where:

  • § E § — total expense
  • § M § — market price of the stock
  • § X § — exercise price of the option
  • § N § — number of options granted
  • § T § — tax rate (as a decimal)
  • § r § — discount rate (as a decimal)
  • § T § — option term (in years)
  • § e § — base of the natural logarithm (approximately equal to 2.71828)

This formula calculates the total expense by considering the difference between the market price and the exercise price, adjusted for tax and discounted over the term of the option.

Example Calculation

Let’s say a company grants 100 stock options with the following parameters:

  • Market Price (M): $12
  • Exercise Price (X): $10
  • Number of Options (N): 100
  • Tax Rate (T): 20% (0.20)
  • Discount Rate (r): 5% (0.05)
  • Option Term (T): 5 years

Using the formula:

§§ E = (12 - 10) * 100 * (1 - 0.20) * e^{-0.05 * 5} §§

Calculating this gives:

  1. Difference in price: $2
  2. After-tax value: $2 * (1 - 0.20) = $1.60
  3. Discount factor: e^{-0.25} ≈ 0.7788
  4. Total Expense: $1.60 * 100 * 0.7788 ≈ $124.61

  • Exercise Price (X): The price at which the employee can purchase the stock under the option agreement.
  • Number of Options (N): The total number of stock options granted to the employee.
  • Tax Rate (T): The percentage of tax that will be applied to the income generated from exercising the options.
  • Discount Rate (r): The rate used to discount future cash flows to their present value.
  • Option Term (T): The duration for which the stock options are valid before they expire.
