11. Restructuring Activities

In December 2018, we announced a restructuring plan to improve efficiencies and reduce costs within the Company, which impacted a total of 21 positions. We expect to incur total restructuring expenses of approximately $1.5 million, of which $0.7 million had been incurred for the year ended December 31, 2018. We anticipate the majority of restructuring activities to be completed by the end of first quarter 2019.

The following table summarizes the accrual balance and utilization for the year ended December 31, 2018 (in thousands):
