Segment Reporting [Abstract]

Segment Reporting

Note 14. Segment Reporting

We operate primarily through three business segments: diagnostic and information technology-based products and services for the veterinary market, which we refer to as the Companion Animal Group ("CAG"), water quality products ("Water") and products for livestock and poultry health, which we refer to as Livestock and Poultry Diagnostics ("LPD"). We also operate two smaller operating segments that comprise products for milk quality and safety ("Dairy") and products for the human point-of-care medical diagnostics market ("OPTI Medical"). Financial information about our Dairy and OPTI Medical operating segments is combined and presented with one of our remaining pharmaceutical product lines and our out-licensing arrangements in an "Other" category because they do not meet the quantitative or qualitative thresholds for reportable segments.

The following is a summary of segment performance for the three months ended March 31, 2012 and 2011 (in thousands):
