Segment Reporting [Abstract]  
Business Segments Information BUSINESS SEGMENT INFORMATION
The Company operates its business in two distinct reportable segments: “Stormwater” and “Wastewater”, which are primarily organized based on products. The CODM for ADS is the Chief Executive Officer (“CEO”). The CEO reviews financial information and makes operational decisions based on Net sales and a measure of operating profit, Segment Adjusted EBITDA, a non-GAAP financial measure.
Certain selling and general and administrative expenses are not allocated to the segments, including non-operating functions such as legal, facilities management, and investor relations. A measure of assets is not applicable, as segment assets are not regularly reviewed by the CODM for evaluating performance or allocating resources. The Company does not aggregate operating segments to form reportable segments.
The following table sets forth reportable segment information with respect to the amount of Net sales contributed by each class of similar products for the periods presented:
