17. Restructuring Costs

In

May 2019,

we approved a severance plan that included a workforce elimination of approximately

38

positions in the U.S. and internationally. In

October 2019,

we determined to close our Taiwan branch office by

December 31, 2019,

which resulted in elimination of approximately

17

additional positions by the end of

2019.

An involuntary termination benefit plan was provided to employees of the Taiwan branch in order to reduce go-forward operating costs and re-align our go-forward business model. The costs associated with these actions consisted primarily of charges for restructuring costs related to severance and benefits, and a non-cash impairment charge related to certain software development cost assets. We incurred aggregate restructuring charges of approximately

$2.3

million associated with these actions during

2019,

beginning in the

second

quarter of

2019.

During the

twelve

months ended

December 31, 

2020,

we did

not

incur charges for restructuring costs under this plan. For the

twelve

months ended

December 31, 2020

,

$0.5

million in restructuring costs were paid and there is

no

remaining balance of accrued restructuring charges on our consolidated balance sheet at

December 31, 2020.
