According to federal securities law, employees are not allowed to receive more than $100,000 worth of exercisable incentive stock options (ISOs) in one calendar year. If a company grants a number of options to an employee that exceeds this amount, any options over the limit will be treated as Non-Qualified Stock Options (NSOs). The $100,000 limit is calculated using the fair market value of the stock for which the options are exercisable, as of the grant date. An important component to the $100,000 limit is that it applies to options that become exercisable for the first time during a calendar year.
For example, let’s say you are the CFO at Company X, and want to grant some options to your employee Thomas Edison. We’ll assume that at the time of the grant (1/1/2020), the fair value of common stock (and by consequence, the strike price of the options) is $.50 per share. If you grant Thomas 500,000 incentive stock options (ISOs), are you violating the $100k limit? It depends on the vesting schedule. If the options granted to Thomas vest monthly for 48 months (with the first vesting occurring on 2/1/2020), during the first year (2020) roughly 114,500 (11 months’ worth) options will vest, or become exercisable. The aggregate value of the vested options for that year (2020) is 125,000 * .5, or $62,500. Since this is below the $100k limit, all of the vested options are treated as ISOs.
Now let’s look at a slightly different example. Just as above, we’ll assume that Company X grants 500,000 ISOs with a strike price of $.50 to Thomas Edison. In this example, however, the vesting schedule is a little different. Instead of monthly vesting for four years, you use a four-year plan with a one-year cliff. 1/4 of Thomas’ options will vest and become exercisable on the 1-year anniversary of the vesting commencement date (1/1/2021), with the remaining 3/4 vesting monthly for 3 years after that. In this case, during the first year (2020) no options vest, because Thomas hasn’t hit his one-year cliff yet. The second year, however, about 239,500 options will vest – 1/4 on 1/1/2021 and 1/48 a month for 11 months. The aggregate value of the vested options for 2021 is 239,500 * .5, or $119,750. Uh oh, an ISO 100k violation. What this means is that the last $19,750 of options must be changed to NSOs to comply with law.
Capshare automatically detects and notifies you in the event of an ISO 100k violation on your cap table.
Note: If the option grant is marked as early exercisable, the full value of the option is applied on the grant date.
