13. Segment Information

Beginning January 1, 2017, the Company realigned its internal management reporting structure to incorporate the New Business into the existing business, and reorganized its current reportable segments. The realigned internal management reporting structure resulted in three new reportable segments for review by the CODM. Beginning January 1, 2017, the Company’s CODM, its chief executive officer, receives and reviews financial information in this format. The Company is reporting its results using the new reportable segment structure and has restated prior periods to conform to the change in reportable segments. Those segments are Activated Carbon, Advanced Water Purification, and Alternative Materials.

The manufacturing and marketing of granular and powdered wood-based activated carbon and coal-based activated carbon reactivation portions of the New Business were combined with the existing Activated Carbon and Service segment and renamed the Activated Carbon segment. In addition, sales of carbon adsorption equipment and associated costs previously reported in the Equipment segment were combined into the new Activated Carbon segment, as this activity is now aligned with the associated leasing of this same equipment. Diatomaceous earth and perlite filtration media sales and associated costs of the New Business are being reported in the newly created Alternative Materials segment, which also includes the carbon cloth sales and associated costs that were previously reported in the Consumer segment. The previously reported Equipment segment has been renamed the Advanced Water Purification segment, and now excludes any carbon related equipment sales. In addition, some product sales and services related to the ultraviolet light and advanced ion exchange separation technologies that were previously included in the Activated Carbon and Service segment are all now reported in the Advanced Water Purification segment.

The Activated Carbon segment manufactures and markets granular and powdered activated carbon for use in applications to remove organic compounds from liquids, gases, water, and air. This segment also consists of activities related to activated carbon including reactivation of spent carbon and the sale or leasing of related equipment, and maintenance at customer sites. The Alternative Materials segment supplies diatomaceous earth and perlite filtration media for use in applications for decolorization, purification, decontamination, and filtration of liquids in various applications including food and beverage, industrial and pharmaceuticals, as well as carbon cloth for use in military, industrial, and medical applications. The Advanced Water Purification segment provides solutions to customers’ water process problems through the design, fabrication, and operation of systems, as well as the sale of materials and services that utilize the Company’s enabling technologies: ultraviolet light and advanced ion exchange separation. Intersegment net sales are not material.

During the third quarter of 2017, the Company incurred expenses associated with the Pending Merger. These expenses have not been allocated to a reportable segment, but are separately identified in the table below which shows the results of operations:

As a result of the change in the segments, a portion of goodwill previously included in the Activated Carbon segment related to the ion exchange business was reassigned to the Advanced Water Purification segment. As of September 30, 2017, goodwill balances were $44.5 million in the Activated Carbon segment, $19.5 million in the Alternative Materials segment, and $12.1 million in the Advanced Water Purification segment. During the nine months ended September 30, 2017, goodwill increased by $2.5 million and $1.7 million in the Activated Carbon and Alternative Materials segments, respectively, as a result of post-closing adjustments made during the measurement period relating to the New Business acquisition. Additional fluctuations in the goodwill balance since December 31, 2016 reflect the effect of foreign currency translation.

Segment assets, which are reviewed by management, consist of the total of the net property, plant and equipment, intangibles, and goodwill balances on the Company’s condensed consolidated balance sheets as follows:
