(1)

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 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.

(2)

Products included within certain of the product categories listed in the table above differ from those included within the similarly named reportable segment. 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 those sales originated, while the classification of products within the product categories listed above includes sales originating from multiple call points within the customer's organization.

(3) Other revenues in the table above comprise the Company’s respiratory, urology and cardiac product categories.
