(15)	Segment Information and Concentrations of Risk

Concurrent with the restructuring initiative in April 2010, we reorganized our operations, and the leadership thereof, from discrete operating business units to company-wide functions. As a result, we no longer internally report on a business unit basis. Our Chief Executive Officer assesses performance and allocates resources within Merge Healthcare based on the company-wide operational results, including revenue. Therefore, we believe that effective in the second quarter of 2010, we have a single reportable segment.

Cash in Excess of Federally Insured Amount

Substantially all of our cash and cash equivalents are held at a few financial institutions located in the U.S., Canada and the Netherlands. Deposits held with these banks exceed the amount of insurance provided on such deposits. Generally these deposits may be redeemed upon demand and, therefore, bear minimal risk.

Net Sales and Accounts Receivable

The majority of our clients are OEMs, imaging centers, hospitals, contract research organizations, health IT, device and pharmaceutical companies. If significant adverse macro-economic factors were to impact these organizations, it could materially adversely affect us. Our access to certain software and hardware components is dependent upon single and sole source suppliers. The inability of any supplier to fulfill our supply requirements could affect future results.

Foreign sales account for approximately 9%, 10%, and 23% of our net sales in 2011, 2010, and 2009, respectively, and sales in foreign currency represented approximately 2%, 1%, and 2%, respectively, of our net sales in 2011, 2010 and 2009.
