13. Employee Benefit Plans

We participate in a number of individual defined contribution pension plans for our employees in Sweden. We contribute between 4.5% and 30% of the employee’s annual salary to these pension plans depending on age and salary level. Contributions relating to these defined contribution plans for the years ended December 31, 2022 and 2021 were $555,000 and $587,000, 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, 2022 and 2021 were $6,000 and $10,000, respectively. In Taiwan, we contribute six percent (6%) of the employee’s annual salary to a pension fund which agrees with Taiwan’s Labor Pension Act. Contributions relating to the Taiwanese pension fund for the years ended December 31, 2022 and 2021 were $4,000 and $2,000, respectively.
