Segment information

Note 11 — Segment information

          We report segments on the basis of services offered and have determined we have two reportable segments: PBM and EM. Our domestic and Canadian PBM operating segments have similar characteristics and as such have been aggregated into a single PBM reporting segment. During the third quarter of 2011, we reorganized our FreedomFP line of business from our EM segment into our PBM segment. Historical segment information has been retrospectively adjusted to reflect the effect of this change. As described in Note 4, our PMG line of business was classified as a discontinued operation in the second quarter of 2010. The results of operations for PMG, previously included in our EM segment, are reported as discontinued operations for all periods presented in the accompanying unaudited consolidated statements of operations in accordance with applicable accounting guidance.

          Operating income is the measure used by our chief operating decision maker to assess the performance of each of our operating segments. The following table presents information about our reportable segments for the three and nine months ended September 30, 2011 and 2010.
