Employee Benefit Plans

13. Employee Benefit Plans

We participate in a number of individual defined contribution pension plans for our employees in Sweden. We contribute five percent (5%) of the employee’s annual salary to these pension plans. For the Swedish Management we contribute up to fifteen percent (15%) of the employee’s annual salary. Contributions relating to these defined contribution plans for the years ended December 31, 2016, 2015 and 2014 were $398,000, $306,000 and $249,000, respectively. We match U.S. employee contributions to a 401(k) retirement plan up to a maximum of six percent (6%) of an employee’s annual salary. Contributions relating to the matching 401(k) contributions for the years ended December 31, 2016, 2015 and 2014 were $33,000, $89,000 and $81,000, respectively. In Taiwan, we contribute six percent (6%) of the employee’s annual salary to a pension fund which agrees with Taiwan’s newly made Labor Pension Act. Contributions relating to the Taiwanese pension fund for the year ended December 31, 2016 and 2015 were $10,000 and $10,000, respectively.
