During the fourth quarter 2016, the Company recognized approximately $1,908 of year-end performance-based bonus expense included in cost of goods sold and operating expenses in the consolidated statement of operations. Such bonus expenses were recognized only in the fourth quarter rather than ratably over each quarter in 2016 as the Company’s board of directors did not approve a bonus plan until the fourth quarter.
