Segment Reporting [Abstract]

Industry Segment Information

Industry Segment Information

The Company discloses information about its operating segments based on the way that management organizes the segments within the Company for making operating decisions and assessing financial performance. The Company evaluates the performance of its operating segments based on revenue and operating income. Intersegment revenue and transfers are not significant. The Company’s management reviews the results of the Company’s operations by the Human Health and Environmental Health operating segments. The accounting policies of the operating segments are the same as those described in Note 1 to the audited consolidated financial statements in the 2011 Form 10-K. The principal products and services of these operating segments are:

• Human Health.    Develops diagnostics, tools and applications to help detect diseases earlier and more accurately and to accelerate the discovery and development of critical new therapies. The Human Health segment serves both the diagnostics and research markets.

• Environmental Health.    Provides technologies and applications to facilitate the creation of safer food and consumer products, more secure surroundings and efficient energy resources. The Environmental Health segment serves the environmental, industrial and laboratory services markets.

The Company has included the expenses for its corporate headquarters, such as legal, tax, audit, human resources, information technology, and other management and compliance costs, as well as the expense related to mark-to-market and curtailments on postretirement benefit plans, as “Corporate” below. The Company has a process to allocate and recharge expenses to the reportable segments when these costs are administered or paid by the corporate headquarters based on the extent to which the segment benefited from the expenses. These amounts have been calculated in a consistent manner and are included in the Company’s calculations of segment results to internally plan and assess the performance of each segment for all purposes, including determining the compensation of the business leaders for each of the Company’s operating segments.

Revenue and operating income (loss) by operating segment, excluding discontinued operations, are shown in the table below:
