(1) Other revenues in the table above include revenues generated from sales of the Company’s respiratory and urology products.

The product categories listed above are presented on a global basis; in contrast, the Company’s North American reportable segments generally are defined based on the particular products sold by the segments, and its non-North American reportable segments are defined exclusively based on the geographic location of segment operations (with the exception of the Original Equipment and Development Services ("OEM") reportable segment, which operates globally). The Company’s EMEA and Asia reportable segments, as well as its Latin America operating segment, include net revenues from each of the product categories listed above.

The methodology used to determine the product revenues included within certain of the product categories listed in the table above differs from the methodology used to classify revenues in our reportable segments, including the similarly named North American reportable segments. The differences are due to the fact that segment classification generally is determined based on the call point within the customer's organization from which the purchase order resulting in the sale originated, while the classification of products within the product categories listed in the table above includes all sales of products within the listed product category, regardless of the call point within the customer's organization from which the sale originated.
