401
(K) RETIREMENT PLAN
 
We have a
401
(k) profit sharing plan (the
401
(k) Plan) for our employees. The
401
(k) Plan is a defined contribution plan covering substantially all of our U.S. employees. Employees are eligible to participate in the Plan after completing
three
months of service and attaining the age of
18.
Employees are allowed to contribute up to
60%
of their wages to the
401
(k) Plan. Historically we have matched
25%
of the employees’ contributions up to
6%
of covered compensation. We made contributions, net of forfeitures, of approximately
$152
and
$286
during the years ended
December 
31,
2019
and
2018,
respectively.
