U.S. The Company's U.S. sales were solely derived from its direct sales force, divided among twelve geographic sales regions.

Europe. For the year ended December 31, 2012, the Company's European sales were derived from (i) its direct European sales force (including dedicated sales agents), serving much of Western Europe, and (ii) five independent distributors serving the markets in Italy (through June 2012), Greece, Turkey, Poland, and Ireland. For the year ended December 31, 2011, the Company's European sales were derived from its direct sales force and independent distributors. For the year ended December 31, 2010, the Company's European sales were derived solely from independent distributors.

ROW. The Company's ROW sales were solely derived from independent distributors. Included in 2012 revenue for Asia/Pacific is $5.6 million of sales of IntuiTrak systems that were not shipped to the Company's distributor in Japan until January 2013 (i.e., representing 2012 “bill and hold” transactions).  Due to applicable medical device regulations in Japan, these IntuiTrak systems could not pass Japanese customs until related Shonin approval was received - which ultimately occurred in late December 2012 (the distributor was solely responsible and bore all the risk for obtaining such approval).  These IntuiTrak systems were subsequently shipped in full to Japan in January 2013. The Company assessed applicable GAAP for these transactions, beginning in the first quarter of 2012, and determined that applicable revenue recognition criteria were achieved in the correspondingquarter that the distributor's written order was fulfilled, physicallysegregated (at the distributor's request), and ready for shipment (at which time full title and risk of loss passed to the distributor, who had no right of return).
