Options to be granted in the future represent an economic cost that you must subtract from future cash flows. We walk through both calculations below. Readers who want to calculate the cost of ESO for this Microsoft case study may also wish to download the accompanying spreadsheet. Please note that certain numbers in this tutorial may differ slightly from the book, as we have incorporated some additional steps in this more detailed analysis.

For example, in this exercise, we adjust for the fact that ESOs are really a "warrant. Readers who want to analyze the cost of Gateway's ESOs may wish to download this spreadsheet.

We can value the economic liability that outstanding stock options using information dislosed in a company's Annual Report.

Here, we walk through this calculation, using Microsoft as a case study. The first step is to value the ESOs using the Black-Scholes economic cost of employee stock options pricing method. In addition to the number of options granted and the weighted average exercise price, it is also necessary to note the " expected life of the options. Note that we are using the option's contractual life, not its expected life.

The appropriate risk-free rate is the rate associated with the risk-free zero-coupon security with the same maturity as the option. In practice, using the rate of return on five-year government treasury bonds will come close to this number. Sources for the ten-year treasury bond include: Another common practice stkck to use the risk-free rate assumed by the company.

*Economic cost of employee stock options* this may be an acceptable shortcut, the value of ESOs may change if rates fluctuate or if the company picks a inappropriate risk-free rate. Companies disclose their own estimate of volatility, which can serve emplloyee the starting point for this analysis. Alternatively, this assumption can be relaxed by assuming econlmic dividend yield is zero and lowering the stock price by the present value of future dividend payments expected during the life of the option.

We can find the dividend for any stock at many sources including Yahoo and CBS Marketwatch. The company also discloses the inputs it uses to calculate the Black-Scholes value of its annual option grants. At first glance, it seems we should multiply this value times the number of outstanding options and have our answer. Employees leaving before their options vest. Most firms use ESOs as a tool to retain valuable employees. Thus, options are typically structured so that an employee who economlc the firm has to forfeit any unvested options.

While losing a optkons employee does not help a company, shareholders do benefit in part from the resulting option forfeiture. To emplooyee this effect, we estimate how long each option group has before it becomes fully vested. Then, using our estimate of how frequently employees leave the firm, we estimate how many of the ESOs in a particular group will exist at expiration date. Stocck next econoomic is to estimate the vesting period of the typical Microsoft option.

The next step is to estimate the number of options that Microsoft employees forfeit annually. Fortunately, Microsoft discloses the number of options outstanding, along with annual option grants, cancellations, and exercises. We can then use this estimate to infer how many of these options ckst actually exist when they become fully vested. Dilutive effect of employee stock options. This is because an ESO forces the company to issue a dilutive share, which lowers the value of each existing common share.

In contrast, a regular option is "written" on existing shares, so when a regular option is exercised, the company does ecoonomic issue any dilutive additional shares. First, however, we need to estimate the dilution that occurs when employees exercise the options in each tranche of ESOs. Finally, we must take into account the benefit that the company will reap from tax savings. The IRS allows companies to deduct the intrinsic value of any option from pretax income during the year in optipns the employee exercises it.

This lowers the cost of the option to the company by the calculated Black-Scholes value times stocj marginal tax rate. Here, we detail the specific steps needed to perform this analysis. It also requires disclosure of the inputs into employde Black-Scholes formula. As with outstanding options, we can use disclosed information together with several assumptions to calculate the Black-Scholes value of option grants. Applying this churn rate to the number of ESOs granted annually, we can estimate how many options we expect will actually exist when they become fully vested.

Next, we estimate the dilutive effects of the annual ESO option grants, following the same procedure as outlined previously. This lowers the cost of the option to the company by the amount of the marginal tax rate. After estimating the historical cost of annual ESO grants, we can then attempt to place a value on future annual ESO grants.
