Note 16 — Business segments and other information

An operating segment is a component of an enterprise (a) that engages in business activities from which it may earn revenues and incur expenses, (b) whose operating results are regularly reviewed by the enterprise's chief operating decision maker to make decisions about resources to be allocated to the segment and to assess its performance, and (c) for which discrete financial information is available. Based on these criteria, the Company has determined that during 2011 it had a single operating segment.

The Company businesses design, manufacture and distribute medical devices primarily used in critical care, surgical applications and cardiac care. Additionally, the Company designs, manufactures and supplies devices and instruments for other medical device manufacturers. Over 90 percent of the Company's net revenues are derived from devices that are considered disposable or single-use. The Company's products are largely sold and distributed to hospitals and healthcare providers and are most widely used in the acute care setting for a range of diagnostic and therapeutic procedures and in general and specialty surgical applications.

As a result of a reorganization of the Company's internal business unit reporting structure and related internal financial reporting, effective January 1, 2012, the Company is changing from one operating segment to four operating segments and from six reporting units to ten reporting units. The change will include converting the Company's current North America Medical business, which will be one of the four operating segments, from one reporting unit to five reporting units. This change in reporting units requires the Company to allocate the assets and liabilities of North America Medical to the new reporting units, and then allocate goodwill using a relative fair value approach. The goodwill attributable to the North America Medical reporting unit was $973.2 million at December 31, 2011. The Company is currently completing the allocation process, and will perform goodwill impairment tests on these new reporting units in the first quarter of 2012. This could result in impairment charges being recognized for one or more of these new reporting units in the first quarter of 2012, which could be material.
