Segment Reporting [Abstract]  
SEGMENT INFORMATION SEGMENT INFORMATION
 
Our President and Chief Executive Officer is the chief operating decision maker ("CODM"). The three operating segments were determined based primarily on how the CODM views and evaluates our operations. The CODM uses segment net revenue and income from operations to assess the performance of the segments by reviewing budget to actual variances on a monthly basis. The CODM also uses segment net revenue and income from operations when making decisions about allocating capital and personnel resources predominantly during the annual strategic planning process. The CODM does not evaluate the segments using asset or liability information.
Description of Segments. We are a global leader in life sciences, diagnostics and applied markets, providing application focused solutions that include instruments, software, services and consumables for the entire laboratory workflow.
A description of our three reportable segments is as follows:
Our Life Sciences and Diagnostics Markets segment is comprised of seven areas of activity.

A portion of the segments' expenses arises from shared services and infrastructure that we have historically provided to the segments in order to realize economies of scale and to efficiently use resources. These expenses, collectively called corporate charges, include finance, tax, treasury, legal, real estate, insurance services, workplace services, human resources, information technology services, corporate development and other corporate infrastructure expenses, costs of centralized research and development and joint sales and marketing costs. Charges are allocated to the segments, and the allocations have been determined on a basis that we consider to be a reasonable reflection of the utilization of services provided to or benefits received by the segments. In addition, we do not allocate certain costs to the operating margin for each segment because management does not include this information in its measurement of the performance of the operating segments. Unallocated costs consist of asset impairments, amortization of acquisition-related intangible assets, acquisition and integration costs, transformational initiatives expenses, restructuring and other related costs and certain other charges. Transformational initiatives include expenses associated with targeted cost reduction activities such as manufacturing transfers including costs to move manufacturing, site consolidations, legal entity and other business reorganizations, in-sourcing or outsourcing of activities. Included in this category are also expenses associated with the recent transformation and company programs to transform our product lifecycle management system and human resources and financial systems.
