(1) During the quarter ended June 30, 2016 we completed the start-up and have commenced commercial manufacturing operations at our activated carbon manufacturing facility in Zhuhai, China. As such, we have placed those assets in-service resulting in the decrease in construction in progress and a corresponding increase in machinery and equipment and buildings from December 31, 2015 to June 30, 2016.
