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, 2015, 2014 and 2013 were $306,000, $249,000 and $184,000, respectively. We match U.S. employee contributions to a 401k retirement plan up to a maximum of six percent (6%) of an employee’s annual salary. Contributions relating to the matching 401k contributions for the years ended December 31, 2015, 2014 and 2013 were $89,000, $81,000 and $66,000, 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, 2015, were $10,000.
