Reportable Segments
 
In accordance with ASC Topic 280, “Segment Reporting,” (“ASC 280”), we have determined our reportable business segments based upon an assessment of product types, organizational structure, customers and internally prepared financial statements. The primary factors used by us in analyzing segment performance are net sales and income from operations.

None of our customers accounted for 10% or more of our consolidated net sales during fiscal 2018, 2017 and 2016.

Our reportable segments are as follows:
 
Endoscopy: designs, develops, manufactures, sells and installs a comprehensive offering of products and services comprising a complete circle of infection prevention solutions. Our products include endoscope reprocessing and endoscopy procedure products.
 
Water Purification and Filtration: designs, develops, manufactures, sells, and installs water purification systems for medical, pharmaceutical and other bacteria controlled applications. We also provide filtration/separation and disinfectant technologies to the medical and life science markets through a worldwide distributor network.

Two customers collectively accounted for approximately 48.0%, 50.2% and 43.7% of our Water Purification and Filtration segment net sales in fiscal 2018, 2017 and 2016, respectively.
 
Healthcare Disposables: designs, manufactures, sells, supplies and distributes a broad selection of infection prevention healthcare products, the majority of which are single-use products used by dental practitioners.
 
Three customers collectively accounted for approximately 45.1% and 43.4% of our Healthcare Disposables segment net sales in fiscal 2018 and 2017, respectively. Four customers collectively accounted for approximately 49.1% in fiscal 2016.
 
Dialysis: designs, develops, manufactures, sells and services reprocessing systems and sterilants for dialyzers (a device serving as an artificial kidney), as well as dialysate concentrates and supplies utilized for renal dialysis.
 
Two customers collectively accounted for approximately 40.6%, 44.2% and 42.6% of our Dialysis segment net sales in fiscal 2018, 2017 and 2016, respectively. These customers are the same two customers noted above under our Water Purification and Filtration segment.
