At face value, the most direct approach to equity compensation would be for the company to award stock to an employee in exchange for work. In practice, it turns out a company will only want to do this with restrictions on how and when the stock is fully owned.
Even so, this is actually one of the least common ways to get equity. We mention it first because it is the simplest form of equity compensation, useful for comparison as things get more complex.
Definition A restricted stock award is when a company grants someone stock as a form of compensation. The stock awarded has additional conditions on it, including a vesting schedule, so is called restricted stock. Restricted stock awards may also be called simply stock awards or stock grants.
technical What restricted means here is actually complex. It refers to the fact that the stock (i) has certain restrictions on it (like transfer restrictions) required for private company stock, and (ii) will be subject to repurchase at cost pursuant to a vesting schedule. The repurchase right lapses over the service-based vesting period, which is what is meant in this case by the stock “vesting.”
Typically, stock awards are limited to executives or very early hires, since once the value of the shares increases, the tax burden of receiving them (without paying the company for their value) can be too great for most people. Usually, instead of restricted stock, an employee will get stock options.
