We are accounting and reporting for our business as a single operating segment entity engaged in the development, manufacturing and sale on a global basis of surgical devices and related equipment. Our chief operating decision maker (the executive management team) evaluates the various global product portfolios on a net sales basis and evaluates profitability, investment, cash flow metrics and allocates resources on a consolidated worldwide basis due to shared infrastructure and resources.

Beginning in fiscal year 2017, we adjusted our product line disclosures to align with the way we review net sales. In doing so, we consolidated our surgical visualization product line into our orthopedic surgery product line for all periods presented. Our product lines consist of orthopedic surgery and general surgery. Orthopedic surgery consists of sports medicine instrumentation and small bone, large bone and specialty powered surgical instruments as well as imaging systems for use in minimally invasive surgery procedures including 2DHD and 3DHD vision technologies and service fees related to the promotion and marketing of sports medicine allograft tissue. General surgery consists of a complete line of endo-mechanical instrumentation for minimally invasive laparoscopic and gastrointestinal procedures, a line of cardiac monitoring products as well as electrosurgical generators and related instruments. These product lines' net sales are as follows:
