Company stock compensation plans are a great way for companies to reward and retain their employees. Restricted stock units (RSUs) are one of the more common forms of this type of compensation. RSUs are granted to an employee and generally vest over specific lengths of time. The longer the employee stays with the company, generally, the more RSUs the employee receives. Individuals who are fortunate enough to receive these benefits should develop a strategy to ensure that they do not become overly concentrated in a single stock position.
