401(k) SAVINGS PLAN

We sponsor a 401(k) savings plan that allows eligible employees to contribute a certain percentage of their salary. Employees are automatically enrolled within the first month of employment and have the ability to opt out. As a safe harbor plan sponsor, we are subject to non-discretionary matching contributions. Currently, we match 100% of the employee's first 1% of eligible pay contributed plus 50% of eligible pay contributed on the next 5%, for a maximum employer matching of 3.5%. Employees vest in the employer matching portions at 25% after the first year of employment, and 100% after two years of employment. Our matching contributions for the savings plan were as follows (in thousands):
