Subsequent to the closing date of the acquisition we expensed that increase into cost of goods sold, of which approximately $3 million was recorded in the fourth quarter of 2015 and $3 million will be recorded in the first quarter of 2016 as the acquired work-in-progress and finished goods inventory is sold.
