We provide a retirement savings plan for the benefit of our employees, including our named executive officers. The plan is intended to qualify as a 401(k) plan so that contributions, and income earned on such contributions, are not taxable to participants until withdrawn or distributed from the plan (except in the case of contributions under the 401(k) plan designated as Roth contributions). The 401(k) plan provides that each participant may contribute up to an annual statutory limit. Participants who are at least 50 years old can also contribute additional amounts based on statutory limits for contributions. Under the plan, each employee is fully vested in his or her deferred salary contributions. Employee contributions are held and invested by the plan’s trustee as directed by participants. We also fully match employee contributions up to the first 4% of salary, which amounts are fully vested.
