Operating Segment And Geographic Information
OPERATING SEGMENT AND GEOGRAPHIC INFORMATION
Our chief operating decision-maker is our Chief Executive Officer, who regularly evaluates our performance based on net sales and net loss before taxes. The preparation of this segment analysis requires management to make estimates and assumptions around expenses below the gross profit level. While we believe the segment information to be directionally correct, actual results could differ from the estimates and assumptions used in preparing this information.
The accounting policies of the segments are the same as the policies discussed in Note 2 – "Summary of Significant Accounting Policies".
In the first quarter of 2013, we consolidated our Clinical Laboratories and Pharmacogenomic Services business segments into a single segment and, going forward, it will be referred to as our Laboratory Services segment. We now have two reportable operating segments, Laboratory Services and Diagnostic Tools. Accordingly, segment results of the prior period have been reclassified to reflect these changes.
